What can be made from a car compressor. Powerful savings: Collect the compressor for painting cars yourself. Adjustment and testing

Recently, compressors have gained popularity among lovers to make. They are made on the basis of almost any engines, calculating the capacity of the basic unit depending on the number of consumers. For domestic workshops, self-made compressor settings made by their own hands are in demand.
Compressors from refrigerators often remain workable after breakdown or obsolescence of the refrigerator itself. They are low, but it is unpretentious in work. And many masters of them make quite worthy homemade installations. Let us see how it can be done with your own hands.

Details and materials

Required details:

• 11-kilogram propane cylinder;
• 1/2 inches coupling with internal thread and plug;
• Metal plates, width - 3-4 cm, thickness - 2-4 mm;
• Two wheels with a mounting platform;
• Refrigerator compressor from the refrigerator;
• Adapter by 1/4 inches;
• The return valve connector from brass;
• Copper coupling connector pipe on ¼ inches - 2 pcs;
• Instrument for adjusting the pressure of the compressor;
• Bolts, screws, nuts, fumalent.

Instruments:

• Welding inverter;
• Screwdriver or drill;
• Millet metal with titanium coating;
• Turbine or bormer with abrasive nozzles;
• Metal brush;
• Roller for copper tubes;
• Deploy keys, pliers.

  Collect compressor

  Step One - Cooking Receiver

  Empty cylinder from liquefied propane rinse good water. It is very important to remove all the remnants of the explosive gas mixture.
  

  

  
  

  

  
  In the end hole of the balloon, I put a 1/4-inch adapter adapter. Write it from all sides with welding, and drown out the screw.
  

  

  
  

  

  
  

  

  
  The receiver put on the wheels and the suborary. To do this, take the segments of metal plates, bend them at an angle and weld on the body from the bottom side. To the corners weld the wheels with the mounting platform. In front of the receiver, mount the bracket.
  

  

  
  

  

  
  

  

  Step second - Mount the compressor

  From above, we exhibit the fastener for the compressor made of metal plates. Check them with a bubble level, and dislike. Sadim compressor on clamping bolts through rubber shock absorbing pads. This type of compressor will be involved only one removal through which the air is injected into the receiver. The remaining two suction air will remain intact.
  

  

  
  

  

  
  

  

  Step Three - fix the check valve and adapter to the equipment

  We choose the milling milling metal in the diameter, and do a screwdriver or a drill hole in the housing under the coupling. If there are protruding forms on the coupling housing, stepping them bormer (you can apply the usual electrofolding or grinder with a grinding disk).
  

  

  
  

  

  
  I exhibit the coupling into the hole and dislike it around the circle. The internal thread should correspond to the step and the diameter of the landing thread on the check valve.
  

  

  
  

  

  
  Use brass check valve for small compressors. Pressure descent removal removal with a suitable bolt, since the adjusting assembly is already provided a trigger valve.
  

  

  
  

  

  
  

  

  
  To install a pressure relay or press space with all regulating equipment, mount another 1/4 inches adapter. The hole under it is done in the center of the receiver, not far from the compressor.
  

  

  
  

  

  
  

  

  
  Spin the check valve with a 1/2 inches adapter.
  

  

  
  

  

  
  

  

  
  Connect a copper tube with a compressor cylinder and check valve. To do this, the ends of copper tubes are fragmented by a special tool, and connect them with brass threaded adapters. Tighten the connection with divorce keys.
  

  

  
  

  

  
  

  

  
  

  

  Step fourth - install adjustment equipment

  The assembly of adjusting equipment consists of a pressure switch (press service) with a control sensor, a safety valve or pressure reset valve, an external thread adapter and several cranes and pressure gauges.
  

  

  
  The first thing is mounted by the pressure relay. It must be slightly lifted to the compressor level. We use an extender-coupling with an outdoor thread, and tighten the relay through the sealing fumlet.
  

  

  
  

  

  
  Through the adapter, we set the pressure adjustment sensor with pressure gauges. Complete the assembly of pressure relief valve and two cranes for hose exit.
  

  

  
  

  

  
  

  

  
  

  

  
  

  

  Pitch Fifth - We connect the electrics

  A screwdriver disassemble the pressure switch housing, opening access to contacts. Summing up the 3-wire cable to the contact group, and distribute each of the wires according to the connection scheme (including ground).
  

  

  
  

  

  
  

  

  
  

  

  
  

  

  
  Similarly, we make a supply of a feed cable equipped with a fork for a power outlet. We spin the relay cover back, in its place.
  

  

  
  

  

  Step Six - Refinement and Trial Start

  For carrying the compressor installation, we attach a special handle to the compressor framework. We make it from cutting a profile square and round tube. Fresh it on the clamping bolts and paint the compressor color.
  

  

  
  

  

  
  We connect the installation to the 220 V network, and check its performance. According to the author, to obtain pressure in 90 psi or 6 atm, this compressor needs 10 minutes. Using the adjusting sensor, the enable compressor after the pressure drop is also adjustable from a specific indicator displayed on the pressure gauge. In its case, the author configured the installation so that the compressor is again connected from 60 PSI or 4 atm.
  

  

  
  

  

  
  

  

  
  Last operation remained - oil change. This is an important part of the maintenance of such installations, because the audit window is not provided in them. And without oil, such cars can work at all long.
  We unscrew the drain bolt at the bottom of the compressor, and drain the work on the bottle. Turning the compressor on the side, pour some clean oil, and twist the plug back. Now everything is in order, you can use our compressor unit!
  

  

Good day! In this article, on the example of its compressor assembly, I want to show a methodology for building compressors from available parts for model airbrushing.

Main elements

The first step must be issued the technical requirements for our fetus of Goblin Engineering.
Since I acquired a new double-acting airbrush, a compressor with the receiver was needed. The fact is that, unlike the airbrush, the single, the new airbrush is capable of driving the flow of air, lock it, and open the air duct. In European countries, many use such an airbrush together with a separate cylinder for compressed air, disposable or reusable, the economic side of this case will be left aside. Air Capacity - receiver- allows you to collect air like such a balloon. If the air will be charged in the air duct hose continuously, then at some point the fitting may not withstand and the hose will fly out. Get the resulting hose on some part of the body - the bearer hurt and unpleasant. And so - the airbrush uses air from the cylinder. So, double-acting airbrush implies the use of the receiver. We will come back to him.

The main thing is actually compressor. We will use the compressor from the refrigerator. Type "Pot" - because, the "cylinder" type compressors are no longer found in the afternoon, and they are all old. We are determined with the choice of the compressor using various sites for the sale of refrigeration equipment. Probably the main criterion will be their price, since the parameters for the injection of air they are approximately equal. There is help, there is weaker. By acquisition - you can go to the store yourself, you can order delivery if they have no retail shop and they work only on the Internet. Before ordering, we look at the compressor model, and write the name of the company, which is producing it, you can using Ctrl + C, you can on a piece of paper. And go to the manufacturer's website. The manufacturer of that compressor, which turned out to be from me - Danfoss, you can download a PDF file with a technical description of the compressor. Download, it is necessary, we will need it!

Let's go back to the receiver. The receiver must serve a container made for the content of gases or fluids under high pressure. It is desirable that it meets the requirements of GOST. Immediately make a reservation - a plastic bottle, plastic tanks, tanks and canisters do not belong to such things. Their use is a blatant security infringement! Consider the containers:

Option first - carbon dioxide fire extinguisher. A good option is tested, keeping up to 10 atm. Very wide selection of capacity - 3,5,10 liters. - Just get enough to get (you can buy, you can get "exhaled"). However, one substantial minus has a metric carving at the entrance. I used it.

Option second - hydroaccumulator. Decent selection of capacity, however, has a small working pressure. At the entrance - a comfortable 1 inch thread. It requires adjustment before use, since inside is divided into a membrane containing carbon dioxide, holding water under pressure. It must be pulled out. Get it - it is elemental to buy in a construction hypermarket or at a stroke.

Option Third - oxygen balloon. Some samples can keep a huge amount of atmospheres, however, in accessibility or cylinders with extremely small capacity, or heavy, massive, for welding works, and get other options is extremely difficult. But if you get some of the medical equipment (I'm afraid it is very expensive ), you can arrange an oxygen bar before assembly !!! \u003d)))

Four option - Cylinders from various gases (propane, etc.) - to get it simple, otherwise similar to the fire extinguisher. However, they say that for compressed air use is not recommended.

Binding links between the gearbox and the receiver, the air preparation unit

Now, when the compressor is defined and what will be the receiver, it is necessary to think about how they will be connected, and how the compressed air will go to the airbrush.
The first is the node that is attached directly to the receiver and provides air distribution between the highways (it is necessary to mention that one of its main characteristics is compatible with the connector on the receiver, about the methods of screwing, I mention later).
Second - pressure switch. The pressure relay must ensure the compressor shutdown when a certain pressure is reached in the receiver and include it when the pressure drops to the minimum value. As a pressure relay, the optimal option is the RDM-5 relay for water supply systems. It is very easy to find it, it is sold in most shopping stores with water pipes. It is necessary to pay attention - the connecting element of the RDM-5 is designed for the outer thread of 1 inches.

The third is needed indexing pressure in the receiver. We buy a pressure gauge with a measurement limit of 10 atm. Such have a connecting size 1. Important - a static device is needed.

Fourth - air preparation unit. In the hose leading to the airbrush, it is necessary to submit a certain pressure. Consequently, a gearbox is needed. The gearbox must have a pressure control limit from zero and up to 8-10 atmospheres. Also, it is necessary that a pressure gauge is attached to it to see the value of the adjustable pressure, as well as the filter oil separator. Because, even from the receiver can fly particles of compressor oil. Attention - in no case, do not buy a filter-lubricator - it performs a diametrically opposite function.

Fifth - consumables, fittings, turns, tees. The main fitting size is 1 inches, in order to calculate their number, it is necessary to build a diagram of the distribution and air preparation node. In addition to them, we will need several adapters from 1 per 1 inches, external and internal.
Looking at all the details and nodes, make a drawing of how it all will look like, for example, like this:

Now we think about the placement of the whole design. As an option - the usual chipboard plate. In order to do not carry the entire design of the apartment in the apartment, let's see the legs, which are easy to find in any furniture store. So that the installation does not occupy a lot of space, I decided to place everything in two floors. So that it was easier to work, draw such a scheme:

You will need either very long M8 bolts or short studs. As well as nuts and washers.
Now, to sum up the planning stage, write a list of required materials.

• Compressor - 1pc.
• Receiver (fire extinguisher) 1 pc.
• Pressure switch - 1pc.
• Manometer - 1pc.
• Filter reducer - 1pc.
• Emergency valve -1pc.
• Fittings, adapters - based on the selected scheme
• Various plumbing pads, fum-tape, sealant.
• Cables, switch, plug + different trifles for styling and connecting.
• Flexible hose (desirable oil-stable), a diameter of coinciding with an external diameter of the air fitting at the compressor.
• Chipboard -plates for stand, 4 legs-roller, 4 bolts M8X25 or hairpins M8, nuts, washers and other small hardware, as well as a different tool.

Start assembling!

Compressor assembly

So, the running shopping is completed, the diagram was drawn, attempted the desire \u003d). The first difficulty - with which I encountered is a node at the outlet of the fire extinguisher. There are several options here - dismantle the node, and find masters-welded so that he welded the desired fitting the driver. Due to the consideration, I did not want to look for someone, so I did simply - twisted part of the valve (leaving the inner mechanics, removed the control element). To one of the outputs, an adapter with an internal thread of 1 inches came up, to another with a creak, the adapter was made from 1 to 38. Put the hand on the heart - this (yes, as well as the entire receiver), it was done in violating the rules for the operation of blood vessels. Better still qualitatively weld a new adapter (which, too, of course, not quite according to the rules ...).

The first stage of the compressor assembly is simple - armed with a plumbing adjustable key, a fum-ribbon, sealant (attention, he subsequently freezes - want to do on the century - do not spare!), And twist the adapters for the planned plan. Important note - In order to ensure a hermetic compound, it is not necessary to wrap everything "to the screen" - according to the law of meanness - tees and turns will never stand on the desired angle. Mount the gearbox, pressure gauge, pressure switch, adapter on a flexible hose. Each stage of the process must certainly be accompanied by a fitting to the fire extinguisher receiver.

The second stage of assembly is carpentry work. I took the ready-made chipboard of the plates "from stocks" and screwed furniture wheels on self-drawing to them, pre-crabmed by a thin drill of seats for them (so they screw themselves exactly at the place and much easier). Be sure to go to the newly made product on the apartment (it is necessary to check it out! \u003d)) - ATTENTION AND INDEPENDED TO THE DOMEST TO YOU is provided to you (from the category of harmful councils, and then it would be worth it to leave the prescription "Never repeat it yourself"). As I did a two-level stand, then the next step was stated and drilled holes for the heels. Approximately the middle of each heel screwed the nuts, measured the perforated tape with the margin (so that it turned out the "bed" for the fire extinguisher) and reedded the last place to be intended for it.
Attention!!! All filth places perflectors are sure to become a tape or other soft material in order to avoid injury, or treat, so that there are no sharp edges and burrs.

After the positioning of the fire extinguisher from above, there were two more perforated tapes and fixed nuts.
If you are using a prepared hydroaccumulator as a receiver, then most of the small (5, 6, 8 l) models of the "horizontal" type are available, there are remarkable brackets from below and from above. The lower can be fastened to the base, and to the top to put the compressor.

In my case, which I use as an example, the design consists of two levels. "Second floor" designs before installing must be prepared. We find suitable holes on the boom of the compressor (there are many of them), and, withsting geometry, place and drill them on the "second floor". Nothing, if the holes are somewhat more than the diameter of the bolts (I used M8), wherever I needed I used wide washers. Mount the "second floor" plate, depending on the scheme that we talked about in the first part.
Put a compressor. In order to reduce vibration, it is necessary to provide some damping elements. I have adapted the usual plumbing silicone gaskets as them, making the shock absorber from them. Fix the compressor, do not forget to put the washers.

We try to receive the air distribution module. If something rests, or just unsuccessfully located, the design can be changed. After fitting - screw. With the help of a flexible hose, fum-ribbons and clamps connect the compressor outlet and the inlet of the air preparation unit. The clamps must be well tightened, providing a dense fit of the hose - from the compressor side, otherwise, can ride and splashing oil, and from the side of the air distribution module - tors, respectively, the air.

First, a little theory about the engine used by the compressor. The compressor, which we consider as an example, uses a single-phase asynchronous machine. Therefore, to run it, you need different auxiliary devices. In our case, this is a launcher with a capacitor. Carefully learn the instructions for the compressor! Types of devices that ensure the drive start can vary greatly from different models.
Now the most basic - you need to work with the installation scheme. There are several pitfalls here:

1. The compressor is extended from the usual connection scheme. To earn it, you need to install a jumper.
2. It is advisable to provide protective elements (circuit breaker) - the question is controversial, in principle, under any excesses, a machine gun should be triggered to a group of sockets, to which the compressor is connected - to put another machine, in my opinion it is not necessary.
3. The connection line must necessarily go through the relay and switch.
4. Sometimes, a condenser must be connected to the compressor. It depends on its type. Be sure to see the characteristics and guide for the compressor used.

Connection must be carried out according to the following scheme:

From the plug-fork, we conduct a phase wire (L) to the switch. Next, we connect the phase wire to the desired terminal of the relay. The zero wire (N) remains intact, in case there is a ground wire, if there is no last, we bring the zero wire to the terminal for grounding the relay (the protective reinforcement is obtained), from the relay we carry the phase and zero wire to the compressor drive launcher (such a box It is on the housing), and by the scheme we connect to the appropriate terminals. It turns out something like this:

General view of the connection scheme. Connection diagram RDM-5 relay. Please note - we use the L1 terminal for connecting the phase, as well as the appropriate terminal on the top of the pipe - the wire will go to the compressor. L2 is not used! Also, in any case, do not connect the pads with each other - then the relay will not work.

From the ordinary plug (2.5 mm2 cable), through the switch, to the pressure switch (there is marked where to connect) and to the compressor. The cable at the fork can be of two types - with the ground, phase and zero, if you have a new home, or just with a phase and zero if the house is old. In principle, you can not bathe, and start the land on the zero conductor, as is done in old houses.
So, now so that the system will earn - set the jumper. It is installed directly on the terminal block of the starter. It is best to connect to soldering, but you can use the crimp contacts of a suitable type (they are specified in the compressor description). The jumper is shown in blue:

Connection diagram of jumper in the starting device.
This jumper is very important, as it provides the connection of the windings to the phase.
At the end, neatly lay cables using plastic ties and self-adhesive sites for them. Carefully inspect the cables for the integrity of the isolation, as well as check each connection to the mechanical strength. Carefully check if there are no possibilities for short circuit - each wire must be carefully cleaned and have contact only with a terminal intended for him.

Now - check everything, launch, and begin to paint the model! \u003d)

In contact with

Private house or in the garage requires compressed air. But the main problem is that the equipment capable of providing its required amount has a rather high cost. At the same time, if the Master does not do similar works professionally, it makes sense to spend big money, which means you need to look for more cheap options for solving the issue. One of these is the manufacture of an air compressor with your own hands from the girlfriend. It is about this that will be discussed in today's article.

The main node of such equipment is a supercharger consisting of an electric motor and pistons. However, it is worth noting that compressors can be intended for various purposes. For example, a car device intended for tire swap is also called a compressor, but it cannot be applied to supply air to the crash. The thing is that the air is unevenly supplied by a similar device, which is unacceptable when the surfaces are painted. For uniform feeding to the paintopult, the device is completed with a special reservoir - the receiver.

Preparation for the manufacture of an air compressor with your own hands

Work on the manufacture of a self-made compressor, with their own hands begins with the main node - the supercharger. Therefore, first of all, it should be declared that it will serve its base. The supercharger can be dismantled not only with various home appliances, which served his age, but also from the engines of some cars.

Photo: DRIVE2.RU

Many masters professionally engaged in airbrushing or other works that require compressed air, in small rooms, prefer precisely by air electrical compressors 220 V, made with their own hands. This is due to their more quiet (in comparison with the factory options) work.

Receiver for compressor with your own hands: what to do it

The easiest option here will be the use of a tubeless wheel from the car, but it is worth remembering that the disk for traveling after modernization will be already unsuitable. But such a homemade receiver for the compressor is most used as simple as possible, and therefore more acceptable for small workshops, such as aerography.

Photo: krsk.au.ru.

If a larger air is required, it is best to use a fire extinguisher or an old gas cylinder as a receiver in the manufacture of a compressor.

Supercharger, Pressure Gauge and Other Details

If you plan to use a powerful supercharger dismantled with old equipment, you must purchase a pressure gauge and an emergency valve that will not allow pressure in the receiver to rise above the permissible. As for the simplest compressor from the old wheel, it is quite suitable for a car device operating from the cigarette lighter and used to swing tires. However, such a supercharger can create an overpressure that will lead to a tire rupture. Such a situation is very dangerous and fraums are sometimes not compatible with life. Therefore, you can not forget about the emergency valve in any way.

Photo: DRIVE2.RU

Consider an example of the simplest compressor based on the automotive electric pump and the tubeless wheel as a receiver.

How to make the simplest compressor with your own hands

To work, you will need to purchase an emergency valve and paging fitting (nipple, spool, "nipple"). In the wheel disk, it is necessary to drill an extra hole for it, as well as for the emergency valve. Next, swap fitting and valve are installed on their place, the wheel is collected. It remains to connect a car electric pump to one of the spacing fittings, and the second hose of the removal to the paintopult or airbrush. Now, after filling the wheel with air, a mini-compressor, made with your own hands, can be used for its intended purpose.

Making compressors with your own hands based on various devices

Homemade compressors can be made using the parts from the refrigerator or vacuum cleaner as the base. Such devices, with their manufacture, will not require large labor costs, and there will also not be to spend a lot of electricity. If the master required a more powerful device, then for the manufacture of the compressor, you can use the equipment, for example, from the car ZIL 130, KAMAZ, or other machine, in which compressed air is used.

It is worthwhile to understand the manufacture of such devices.

How to make a compressor from the old refrigerator

The process of manufacturing an air compressor from the refrigerator is extremely simple. This will require:

• receiver;
• filter and moisture meter separator;
• gearbox with manometer;
• the compressor itself from the refrigerator, which is dismantled together with the relay;
• safety (emergency valve).

Air Compressor Device Scheme

For greater understanding of how such a device is going, you can look at the schematic pattern below. However, the author of this picture was made one of the main bugs of the novice. It is in order to show it, the edition of Homius and led to an example this image.

Photo: tehnika.expert.

As you can see, the author offers to install a filter between the receiver and the compressor, which is not recommended. The fact is that with an increase in pressure, the plastic case may simply break. In this place there should be an oil separator. The filter itself is mounted on the compressor tube through which the air is absorbed.

Photo: DRIVE2.RU

Also, the diagram does not specify an emergency valve that must discharge excessive pressure. It is best to install at the receiver itself.

How to make a compressor from the vacuum cleaner: is it possible

Many beginner masters, first heard the possibility of making a compressor from an old vacuum cleaner, begin to ask questions about how the receiver is connected to it. However, this is all from the series "heard the ringing, but does not know where he is." The fact is that the name "compressor" is difficult to attribute to a similar device. Rather, this is a pulverizer, which is not worth a lot. Although, if we talk about the possibility of blinking the walls in the cellar or other similar works, this device can greatly relieve work. Such nozzles that were put on the usual glass jar were complete with Soviet vacuum cleaners, and now they are much easier to order on Chinese resources or acquire from the hands than to produce themselves.

Production of the compressor for aquarium with their own hands

Such devices are pretty in demand among consumers. But you should immediately make a reservation - there is practically no meaning in such work. The cost of such equipment on the Russian market is minimal, but it can take it decent time. In addition, some details still have to acquire. Therefore, it is worth thinking first if you need to try a similar job?

Tip! Before starting manufacturing with your own hands, any device must be calculated, whether there will be a benefit from such a job, "there is a game of the candle."

Compressor for painting cars: how to make with your own hands

The most popular compressors manufactured by their own hands can be called equipment for painting a car or any other details and mechanisms. In addition to a solid receiver, it will also require a different supercharger, which will be filled with air capacity much faster than refrigeration equipment. Such a device is best made from the finished automotive compressor by connecting the electric motor to 220 or 380 V as a drive.

Scheme and procedure for assembling a piston compressor

If we consider a schematic representation of a similar compressor, it becomes clear that there is nothing overhaul in it. The main thing is not to forget to include a filter with a rigid housing that can withstand the injected pressure. It is installed at the outlet of the receiver in front of the air supply hose on the spray gun.

Photo: SAMODELKINDRUG.RU.

Many do not understand the appointments of this element, considering it completely unnecessary, but this opinion is wrong. The fact is that the air in the receiver is in a compressed state, and the change in the density of any substance, as is known, changes its temperature. As a result of compression and subsequent release of air and the occurrence of changes in temperature, condensate occurs, which can get into the paint together, which will certainly affect the quality of the final result. The filter is the same eliminating.

Homemade compressor assembly nuances for car painting

The main task here is the strength of the hoses and the density of the compounds. Therefore, it is recommended to use to transmit air from the supercharger to the receiver and further to the filter copper tubes. The use of an oxygen hose will be optimal from the filter to the most paint. It is reinforced by fiberglass, and therefore has not only necessary flexibility, but also increased strength.

Quite interesting for the manufacture of the compressor with your own hands the use of equipment from the Ikarus bus and the gas cylinder, which can be found in the picture below.

Regulatory work before launching the compressor

Having gathered with their own hands the compressor for collapse or other works, it should be experienced. However, before that, as subsequently, before each launch, certain actions should be made, namely:

• check the density and reliability of all connections;
• view visually hoses and tubes for cracks or breaks.

After the compressor engine is running, you must check the gearbox gearbox setting. The answer to the question of how to set up the compressor to the right pressure is simple. It is exhibited using a regulator installed on the pressure gauge, by turning the handle to the right and left. A maximum air pressure in the compressor receiver from the engine is controlled by an emergency valve, which is triggered by exceeding the allowable threshold.

Many craftsmen know that you can make a compressor from the refrigerator with your own hands! Can . But, few people know how to do it! In this article, we will try to present an exhaustive answer, how to make a compressor with your own hands so that everyone can create this equipment at home.

After all, if you figure it out, in fact the air compressor is needed in every garage. With the help of the compressor, you can, pump the wheels without visiting a hundred or tireage, supply air to a working pneumatic tool or simply blew dust from the surface treated. So, consider the installation option for painting.

Factory or homemade compressor

Regarding the painting station there is a list of certain requirements. The main condition is the need for uniform air intake, without any impurities. The standard defects that are due to the presence of foreign particles can be attributed to the graininess, shagreen or cavity on the enamel coating. In the case of uneven flow of paint, drums or matte heel may form.

Of course, if you pay attention to branded air compressors, such installations are equipped with all the necessary functions for high-quality airbrush. The only disadvantage of such aggregates is their cost.

In order to save money and at the same time create a functional model that will not give up professional equipment, you need to familiarize yourself with the theoretical information base or view the video on the topic "Compressor for painting a car with your own hands."

The principle of operation of any model, regardless of whether it is self-made or the factory, one and the same. The tank creates excessive pressure. Different air injection method (manual, mechanical). In the case of manual feed, there is a significant saving of money, but a lot of energy is consumed. After all, the process requires constant control.

Automatic inflation makes it possible to avoid these disadvantages, except that the oil for the air compressor requires its periodic replacement. Thus, there is a uniform air supply to the distribution device. In the theory, it looks extremely simple, so you create a working compressor station, possibly in a short time.

We do with your own hands

So, we choose the manufacture of the installation for painting from the ordinary car chamber. The list is needed:

1. Car chamber executing a receiver;
2. Pump with a pressure gauge, performing a supercharger;
3. Chamber nipple;
4. Remkomplekt;
5. Normal awl.

Now you can start making the compressor station. The camera must be checked for tightness, for this it needs to be met. If there are air leaks, it is necessary to solve this problem, or by sticking, or with the help of volcanization of raw rubber.

After that, in the manufactured receiver with a selection, you need to do a hole. A nipple will be placed here through which a uniform jet of compressed air will go.

Additional fitting is attached by attaching. Remkomplekt will help in solving this task. Then the fitting is connected to the paintopult. To check how the air flow comes to you to unscrew the nipple.

At the same time, native nipple remains, it will serve as a valve, and retain excessive pressure. In the end, it is necessary to determine the level of pressure by spraying the paint on the metal surface. If the enamel falls evenly, it means that the installation works well.

In addition, the pressure value can be checked using a pressure gauge. But, its level, even after pressing the aerator key, should not be scorching.

Describing the compressor is easy, but after its manufacture, anyone can make sure that the repair or painting of the car will become much more effective than it was with a canister.

The latter's incidence should be attributed to the fact that it is necessary to avoid water or dust into the car chamber in every way. So that these particles are not subsequently entering the paintopult, otherwise it is necessary to paint again.

As a result of the proper operation, the established installation will work for a long time, but it is better to automate the pumping of the air.

Semi-professional air supercharger

Specialists have repeatedly made feedback on the fact that homemade compressor installations have a longer service life. What the comparison was made with domestic and foreign models.

It is natural, because the installation is made by your own hands. Therefore, we consider the option how to make a compressor from a refrigerator, which will not give up even the products of famous firms. So, for its manufacture, the following list of materials is necessary:

• Receiver for compressor;
• Pressure gauge;
• Relay to control the pressure in the compressor;
• Threaded adapters;
• Fuel filter (gasoline);
• Reducer with an oil-separating filter;
• Cross plumbing with threads ¾ inches;
• Motor for compressor installation;
• Car clamps;
• Motor oil (10W40);
• Switch (220 V);
• Oil resistant hose;
• Brass tubes;
• Ordinary syringe;
• Thick board;
• Comceptor rust converter;
• Filter of the power system (diesel);
• Metal paint;
• Nuts, washers, hairpins;
• Wheels for furniture;
• Sealant, tape FUM;
• Fillet.

Working mechanism

To simplify the procedure, the engine can serve as a compressor from the old refrigeration unit of the Soviet sample. There is one positive moment here, namely, the presence of a starting relay of the compressor.

Soviet models exceed their foreign competitors, producing higher pressure. It is necessary after extracting the executive unit to put it in order, freed from the stood rust.

Rust converter will help to produce compressor processing to avoid further oxidation. Thus, the work motor body will be prepared for the subsequent painting.

Installation scheme

After performing the introductory part, you can start replacing the oil. After all, if you do not crush the soul, then little, which refrigerator managed to be subject to regularly or replacing the oil. However, such a course of events is also quite acquitted, because in this case the system is in full insulation from atmospheric effects.

So, the semi-synthetic oil is quite suitable for this procedure. Especially since it is no worse than compressor oil, and has a sufficient amount of useful additives.

We go further, and finds 3 tubes on the compressor, 2 of which are open, one is posant. In our case, open tubes will be used to circulate air (input and output). To understand how the air moves, you need to apply for a compressor for a short time. After that, remember or record, which air duct draws air, and what, on the contrary, releases.

The appointment of the sealed tube is a regulatory oil change. Therefore, the closed end should be deleted. This will help us with a supreme who need to produce inscribed in a circle of the tube. It should be viewed that the chips do not get inside the compressor.

After it is necessary to break the end of the tube and drain the oil into any capacity in order to establish its volume for subsequent replacement. Then we take the syringe, and pour semi-synthetic, but, in a larger volume than it was fused.

When the oil is flooded, you need to drown out the engine lubrication system. This can be done by selecting the screw, after which this screw is winding the FUM ribbon and tightened into the tube. It's time to remind you that from the output air tube of the supercharger will sometimes be seeded oil drops.

Therefore, an oil separator for the compressor will come to the rescue.

When the designated works are completed, time to start assembling the installation. You need to start with the strengthening of the engine with a launch relay on a wooden base, so that it is in this position as it was on the frame.

This is necessary due to the sensitivity of the compressor relay to the spatial position. To determine more precisely, an arrow must be drawn on the top cover. It is important to observe accuracy here, because, the correct switching of the modes will depend on the installation of the compressor.

Air container

An excellent solution to the problem will be cylinders from fire extinguishers. It depends on their ability to withstand high pressure, in addition, the cylinders have a significant margin of strength, are perfectly suitable as attached equipment.

So, take as the basis of the OU-10 fire extinguisher. Its working volume is 10 liters. According to the technical characteristics, the cylinder withstands the pressure - 15 MPa. Now you need to unscrew the locking device from our billet, then screw the adapter.

In this case, in the case of detection of traces of corrosion, it is necessary to remove them with a rust converter. Of course, the external deletion is simple, but internally will require patience. Therefore, we fill the converter inside the cylinder, and we take the contents.

After cleaning, you can screw the plumbing cross. Thus, two work details of our compressor installation were prepared.

Installation of parts

To make it easier to store and move work items, they are best located on the same database. As it has already been previously said, we need a wooden board that will serve as a basis for reliable fastening of the engine, as well as the fire extinguisher housing.

Therefore, as the engine mount, we will use threaded studs that need to be used in pre-drilled holes. Of course, plus the nuts (washers) will also be needed.

Then you need to position the receiver in a vertical position, here there will be 3 sheets of plywood. At the same time in one sheet you need to do a hole for a balloon. The remaining sheets are mounted with self-draws to the main board and glue with the sheet that holds the receiver.

But, on the eve you still need to wipe the recess under the bottom of the receiver in the wooden base. And finally, that the design is maneuverable, you need to fasten the furniture wheels to its base.

After all made, you need to protect the system from possible dust. A gasoline filter of coarse fuel purification will come to the rescue. It will perform the function of the air intake.

The rubber hose and the supercharger inlet tube will be involved. It should be noted that at the entrance of the compressor station is low pressure, and, it means, the gain of contact with the help of automotive clamps is not necessary.

Thus, we have created an input filter for compressor installation. At the outlet of the station you need to install an oil separator, which will block the ingress of water particles. The power system filter will be used here. Due to the fact that the pressure at the output of the compressor station is increased, automobile clamps will be used from this place.

Thus, the queue reached the oil separatory filter. In this case, it needs to be connected to the input of the gearbox, which is needed for the disconnection of the tank and the output of the pressure supercharger. So, we screw out the exit to the previously prepared crossbar on the left side, and on the right we screw the pressure gauge, thanks to which you can control the balloon pressure. On top of the crossbar need to screw the adjusting relay.

The presence of an adjustment relay will give the ability to set the recruit pressure height range, as well as to interrupt the power circuit in the supercharger. When it comes to the actuator, it is recommended to use RM5 (RDM5).

With these devices, the compressor will be turned on, in the event of a drop in the air pressure in the tank below the set mark and turn off when the specified parameters are exceeded.

The desired pressure is adjusted on the relay using two springs. The function of the large spring is to create minimal pressure, while the small spring is responsible for adjusting the upper limit, actually installing the border of disabling the compressor installation.

RM5 (RDM5) was primary to use in the water supply network, in fact, these are conventional two-contact switches. In our case, one contact is used to connect zero network 220 V, while the second contact is connected to the supercharger.

We carry out the network phase through the toggle switch to connect to the second input of the compressor station. In the presence of a toggler in the electrical circuit, we will be able to make a quick disconnection of the system from the network, which will get rid of the runner towards the socket.

Naturally, all compounds must be released and carefully exhibited. After that, you can paint the finished installation and conduct test tests.

Adjust the pressure

So, after assembling the design, it is quite natural to conduct it. To do this, connect the paintopult, or as an option is a pneumatic equipment. Then, not including the toggle switch, make a plug into the network.

Adjusting relays are installed at minimum pressure, and make the power supply to the supercharger. Do not forget for a pressure gauge that allows you to control the pressure in the tank. After we managed to make sure that the relay turns off the engine, you need to check the tightness of the connections.

A classic soap solution can help here. If the system has been tested for tightness, you can make air remnants from the tank chamber. It is necessary to pay attention to that in the event of a pressure drop below the limits, the relay must start the compressor. In the event of the health of all systems, it is possible to embark on the color of any part.

It should not be loaded by pre-treatment of metal. It is important for us to establish the pressure necessary for painting.

Such experimentation will give us the opportunity to determine the atmospheric size so that the painting of any product happened to the uniform layer. In addition, it is very important that all this process takes place with a minimal number of supercharger.

Thus, you can bother the results. Production of a car compressor, lifting lesson for every motorist.

Of course, it is difficult to argue with the fact that the second version is more difficult and will take longer to manufacture, but, thanks to the system of automatic pressure control, as well as the presence of a supercharger starting work with such equipment, will become one solid pleasure.

In addition, you will not need to control the receiver camera more. Such a station will allow you to paint the car, fence in the village or garage doors.

For the continuous operation of the created compressor, it will be necessary to carry out periodic regulations. . To make a plum of oil, you can use the syringe. In this case, we unscrew the plug hole, we wear a hose on the tube and pumping outlaughter. Also, fresh oil can be downloaded using a syringe. Filters change as needed, including in the case of a decrease in the speed of filling the tank chamber.

Make or buy

Today, the market is filled with a variety of compressor equipment. There are piston installations, vibration units, screw stations and other devices that are manufactured for different purposes. Finished installations can be purchased in auto parts stores or profile sites.

A large range may make it difficult to choose the desired product. But be that as it may, if you decide to buy a finished station, make an emphasis on the study of technical parameters, cost and reviews.

To obtain quality assurance, it is better to purchase equipment of well-known brands, however, an expensive product justifies itself in the event of a professional car repair. Little-known products can bring you, so it is better not to risk.

Often, budget options have low-quality materials. There are often cases of setting facilities, due to instant breakdowns of individual parts, while the warranty repair takes a lot of time.

As already mentioned, his own assembly is often more reliable than factory. An individual plus is the technical parameters. For example, according to statistics, refrigerator compressors serve dozens of years. Regarding the fire extinguisher, it can be said that this product has a tenfold safety margin.

Therefore, it is better not to buy what you are unsure. In addition, after studying the current material, you know what to make a compressor with your own hands, you can even in domestic conditions. The well-made device will become the envy of the neighbors of the garage.

Another story

Let's start with the design of the technical requirements for the fetus of its own engineering. Suppose that it all started with the purchase of a new double-acting airbrush. Therefore, the issue of manufacturing compressor installation with the receiver became extremely necessary.

Double action airbrush has the ability to control the air flow, as well as lock it and open the air duct. In Europe, such a device is used with a separate cylinder for compressed air. So, the compressor with the reservoir serves as a capacity for collecting air, and the airbrush uses this air.

Of course, the main component is the compressor. An old refrigerator will come to the rescue, from which you can remove an excellent compressor. To do this, you can walk on sites that sell refrigeration equipment.

We define at a price, and order delivery, but before you still need to write the name of the manufacturer and visit the site. So, in our case, the manufacturer is Danfoss. On the company's website, we download the technical description of the compressor.

Next, consider this option as the receiver for the compressor with your own hands. Here, of course, a reservoir is needed, which has been manufactured for gas content or can withstand high pressure. Optimally, if such a container meets the requirements of GOST. Therefore, immediately exclude the container, by type of plastic canister or bottles. Consider options for tanks:

1. Carbon dioxide fire extinguisher. Withstand pressure - 10 atmospheres. Capacity - 3 l / 5 l / 10 l. Cons - at the entrance metric thread.
2. Hydroaccumulator. Good capacity, with a small operating pressure. At the entrance convenient carving. Cons - needs to bend, since, from the inside it is divided into a membrane that contains carbon dioxide. The membrane needs to be deleted.
3. Oxygen balloon. Withstands high pressure. Cons - only extremely heavy models are available.
4. Propane cylinder. Overall, analogous to the fire extinguisher, but the manufacturer does not recommend their use for compressed air.

Binding links

After we have decided on the compressor, and chose a suitable product for the receiver, the next step will be their association. In addition, it is necessary to solve the problem to enter the airbrush.

You can start with the node that is attached directly to the receiver, and will provide air distribution. It is necessary to recall that the key factor is its compatibility with the receiver connector. Next, we draw attention to the pressure relay, which will be shutdown and turning on the compressor.

The optimal option for the relay will be RDM-5, which is used for water supply systems. This model is widely available on sale, and is good because its connecting element is designed for an external inch thread.

Then we are determined with the pressure indication in the receiver. To do this, we need a pressure gauge for 10 atmospheres, it also has a suitable connecting size. And we still need a static device.

Then we are engaged in the air preparation unit. In the hose, which leads to the airbrush, you need to submit pressure. Accordingly, there is a need for a gearbox, with the limit of pressure regulation up to 10 atmospheres, and it is desirable that a pressure gauge and filter oil separator attached to it.

Using a pressure gauge, we will control the pressure, and the filter will ensure the incomprehension of particles of the compressor oil from the receiver. But, it is not necessary to be confused with a lubricator filter, which performs the diametrically opposite function.

We will continue to collect materials, and it's time to prepare fittings, turns, tees. As a basic size, we take inch. To determine the amount, the diagram of the distribution and air preparation unit is needed.

We will also need external and internal adapters. If you wish, you can make a plan to make a compressor. The next stage is the placement of the finished design. As an option, chipboard plates can be approached.

Of course, in order not to swear with a mat during the movement of the station on the workshop, it is desirable to immediately resolve the issue with legs-rollers. Any furniture store with joy to sell them. To save space, you can make a two-story design. True, you may need long bolts. So, we summarize the planning stage, the list of components:

• Compressor;
• Receiver;
• Pressure switch;
• Pressure gauge;
• Filter gearbox;
• Emergency valve;
• Fittings, adapters;
• Plumbing pads, fum-tape, sealant;
• Cables, switch, plug;
• Flexible oil-resistant hose;
• Sheet of chipboard
• Legs, bolts, nuts, washers and tools.

We start assembly

The ideal will be the dismantling of the node of the fire extinguisher and the welding of the adapter fitting. An alternative way is to unscrew the part of the valve, leaving the inner mechanics and removing the control element, then screw the adapter to one output with an internal inch thread, to another adapter from 1 to 38.

Using the adjustable key, twist adapters according to the scheme. Next, mounted gearbox, pressure gauge, pressure switch and adapter on a flexible hose.

The next step is the screw to the wheels to the chipboard sheet. Since the design will be two-level, you need to drill holes for the studs. After that, we climb into your place a fire extinguisher.

In the case of using a hydroaccumulator, the assembly scheme is even easier, since it has brackets from above and below. Therefore, the lower mounts are screwed to the base, and the tops serve to install the compressor.

In our case, the second floor must be constructed. For this, the layout is made, the holes are drilled, and the top and bottom floors are fastened. After that, the compressor is mounted on the second floor. Silicone gaskets are suitable for decreasing vibration.

When installing the compressor, we put the washers. We screw the air distribution module to the tank. Using the hose and clamps, tightly connect the compressor output and the input of the air preparation unit.

Now it's time to work with the connection scheme. It will be a relevant jumper installation. The protective elements will not prevent. The connection line should pass through the relay and switch. The connection itself will be as follows.

From the plug, the phase wire goes to the switch. Then connects to the desired relay terminal. In the absence of a ground wire, we start the zero wire on the terminal grounding the relay.

Already from the relay, the phase wire and zero wire goes to a starting device for driveing \u200b\u200bthe compressor station and are connected according to the scheme to the desired terminals. Further, on the terminal block of the starter, we set the jumper by spike.

It will ensure the connection of the windings to the phase. Cable can be laid in plastic ties. Check and start the installation. Then paint it.

The compressor can be used in a wide variety of areas - to swing tires, airbrushes, painting parts etc. Possessing the necessary tools and certain technical knowledge, it is quite possible to manufacture this unit based on the usual refrigerator. The homemade compressor gives about 7 atmospheres, which is quite enough for the ordinary garage workshop, so many are increasingly thinking about how such a compressor can be made? Refrigerator compressor do it yourself it turns out quite quiet and, most importantly, cheap at its cost.

On average, the manufacture of this unit will require order one thousand rubles For all components.

Before trying to make our old refrigerator, you must compare two of these options, i.e. sold in specialized stores, and our homemade option. All can be highlighted several main differences Between them:

• In the design of the factory compressor, there is an electric motor that transmits torque to the working chamber through the belt transmission. As for the homemade compressor, it consists of a housing and the engine itself, without belts.
• In the factory embodiment, automatic pressure reset, input and output filters, pressure indicators, etc. have already been installed. The compressor from the refrigerator will have to install the adjusting equipment independently, given all the features.
• Despite the fact that most factory compressors are equipped with automatic systems, in some budget models, such a feature is not implemented. In other words, these aggregates will have to be turned off independently, checking the time by the clock. Homemade compressors, mainly equipped with a protective relay, turning off the engine when the risk of overheating occurs.
• In some factory models, there may be no lubricant. Of course, they have a small motor life, but there are no different exhausts. This circumstance is very important, especially if the paintopult behaves quite capriciously, without suffering different impurities. As for homemade compressors, it is plenty of oil. By the way, you need to pay attention to which it is to pour - synthetics very badly combined with usual, so it is not necessary to pour everything that fell.
• The main feature of the homemade compressor is that it works very quietly, especially if you put all the tubes on it correctly, observing tightness. As for the factory compressors, they behave more noisy, so its use is possible only outside the house.
• The cost of making a self-made compressor is very low, because the main components we take from the old technique, and the adjusting equipment will cost us one thousand rubles. As for the factory compressor, then the case is different.
• In the factory compressor it is impossible to make any technical changes. In other words, if the unit is not enough powerful, it is possible to use it only as a pump for, no more. Homemade options are good because you can add some details, such as a large receiver, thanks to which you can significantly increase the power of the device.
• The factory compressor is a complete technical device, so any improvisation is impossible with it. With the homemade unit you can do almost everything - to bring some details outside the body, or hide everything in one box, and on top to attach a handle for convenience of transportation.
• On the homemade compressor you can install the fan so that it is cooled from the outside.

Most refrigeration compressors possess some restrictions in terms of their work. Total shared several modes:

• Normal - from 16 to 32 C.
• Subnormal - from 10 to 32 C.
• Tropical - from 18 to 43 C.
• Subtropical - from 18 to 38 C.

However, combined modes are more common, possessing a different range.

So, homemade compressor maybe much more efficiently factoryIn terms of work with air.

Dismantling works

To make a homemade compressor from the refrigerator, it is necessary to produce initial training. It is in certain dismantling work, i.e. It is elementary to remove the compressor from the refrigerator itself. It is located behind the refrigerator, in its lower part. To remove, we need an elementary set of tools: pliers, cape keys and two screwdrivers (plus and minus).

The compressor is located between the tubes that are connected to the cooling system. These tubes need to be bought off with the help of pliers, but in no case can be cut off with their hacksaw. The fact is that with this method inevitably the fine chips are formed, which can get inside the compensator.

Then go to the removal of the start relay is the usual black box, with wiring sticking out of it. We unscrew the mounts, then snack the wires that lead to the fork. You must not forget to mark the top and bottom of the launch relay - this is useful for us later. By the way, all the fasteners elements also take together with the aggregate itself.

Checking performance

After we removed the compressor, you need check its performance.

The fact is that we remove the device from the old refrigerator, so you need to make sure that our unit is still alive. So, flatten the tube pliers - it is necessary so that air flow passed through them. Next, we need to put a start relay to the position in which it stood in the refrigerator design. This is very important, because with the wrong position there is a risk of a device breakdown, as well as the failure of the compressor winding.

On the case of the relay there are wires to which you need to screw the piece of wire with a fork. The connection site is better wrapped with a tape to eliminate the risk of lesion to the current. Turn on the device into the outlet. If you did everything right, the compressor will work, and air will go from his tubes. By the way, it is necessary to mark from which tube the air flow comes, and which goes.

Step-by-step instruction

Before proceeding with independent making, you need to make sure that you have all the necessary materials and tools.

We offer to watch video with a detailed description of the process of one of the manufacturer's options.

Read the same: We select oil for air compressor

In addition to the compressor itself, which we previously removed from the refrigerator, we will need:

• Receiver. In this case, you can use the body of the old fire extinguisher, or weld the body from sheet metal and pipes.
• Various hoses. At the same time, the length of one hose must be at least 600 mm, and the other two is about 100 mm. In this case, you can take hoses from the car.
• Various consumables - gasoline and diesel filters, wire, clamp, pressure gauge and epoxy.
• Related toolkit, i.e. Screwdrivers, pliers, drills, etc.
• In addition, we need the usual wooden board, which will be the basis of the whole design. Attach the compressor to it using conventional screws. The mount should be carried out exactly in the same position he occupied in the refrigerator design.

We take any plastic capacity of a suitable volume (from 3 liters or more). At the top you need to drill a pair of holes for the sizes of the output tubes. Insert the tubes, after which we pour all the epoxy resin. The inlet tube in which air enters must be located in such a way that there was about 200 mm from its end to the bottom of the receiver. The output tube must be immersed inside ten centimeters.

This is a description of the plastic receiver, but for greater tightness it is best to make a receiver in the iron case. In this case, there is no need to pour all the resin, and the hoses are elementary brewed. To the same, only a pressure gauge can be installed on the iron receiver.

To install it, you need to drill the hole under the nut on the receiver housing. Insert it, then brew. Only then screw the pressure gauge into this nut, after which the work is completed. Now freamed by the receiver to our base with wire. The scheme will be approximately the following:

Our homemade unit is almost ready.

On the Internet there are quite a lot of photos and video of his work, for example, it is shown how it is used in airbrushing and for painting various parts, therefore the feasibility of its manufacture is quite obvious. At the end, you need to add several additional strokes to our device.

It is necessary to take one of the hoses, the length of which is ten centimeters, and put it on the filter. If this happens with difficulty, you can slightly heat the end of the hose so that it makes it easier for the fitting. The second end of the hose put on the inlet of our device. In this case, the filter will be protected from dust from entering the housing. The second 10-centimeter hose you need to connect the receiver's inlet and the output compressor. In this case, the connection site is better to tighten the clamps. Our third hose must be put on a diesel filter, and the other end to insert the receiver outlet. At the same time, the free fitting of the filter will continue to join various equipment for airbrushing, a spray gun for painting, etc.

Some technical data and service features

It is quite difficult to definitely say what kind of pressure will show one or another compressor. Here much depends on the specific brand and the operational period of the device itself. By the way, the old aggregates show even greater indicators than modern.

Maintenance of our self-made device is a very important point in operation.

The main works will be to replace diesel and gasoline filters, as well as on the replacement of oil in the device. The design of compressors is present, as a rule, three copper tubes. Two of them we used earlier, and the third remained not touched. It is the shortest and posant at the end. So, draining oil is made through it. To do this, you need to cut off the sealed part, after which it is to drain the processing, the fill is made through it.

Do I need to repair the compressor?

As for the repair of the resulting device, then here everything is personally for yourself - Does it make sense to mess with it or not.

The repair will be in the translaimation of the relay, as well as to replace the oil in the device. If the manipulations did not help, then there is absolutely no need to invent something else. It is best to throw out the device that has served, then make a new one. Moreover, the issue price is not more than 1000-1500 rubles.

Conclusion

In principle, we figured out how to make a compressor from the refrigerator.

The feasibility of its manufacture is difficult to overestimate, because using this device you can produce various works on airbrushing, pumping tires, painting various components and other works requiring pressure.

An additional advantage is that such a device can be used at home, because it makes little noise. In fact, this is the same refrigerator, only without unnecessary parts of the housing.
