How can I use the compressor from the refrigerator: useful tips for the economy. How to make a compressor from the refrigerator as from the household refrigerator make a compressor

The homemade compressor from the refrigerator is most commonly used in a pair with an airbrush or a spray gun, as it works almost silently, takes little space and creates sufficient air pressure. He will suit and in order to punish the wheel of the machine. Next, we will tell you how to make a compressor with your own hands.

Materials and tools for a homemade refrigerator compressor

Compressor. Motor from the old refrigerator and is called the compressor, it is the central element of our product. As it looks, you can look at the photo: details different models can differ, but in general are similar to each other. A start-up relay is attached to the compressor (black box attached), from which the power wire with a fork comes out.

Receiver. The container in which the air compressor will be made. Here options are possible: any tightly closing capacity of 3 to 10 liters from iron or plastics is suitable. It can be an empty fire extinguisher, small tanks, various receivers from trucks, canisters from construction liquids.

Hoses. Three segments of the hose are required. Two 10 cm long and one - 30-70 cm, depending on the form of the receiver and the alleged attachment. It is convenient to use fuel hoses in the car, as they will connect with car filters.

One hose or tube will also be required to connect the finished homemade compressor from the refrigerator with the air consumer itself. Here is the length, the material depends on the specific needs. If you use a compressor with an airbrush, then any thin polyvinyl hose (or the one that is attached to the airbrush) is suitable. When using the compressor on the street it is better to search the hose is thickening.

Clamps. 5 pieces, size 16 or 20 mm.
Tubes. Two pieces - copper or iron, with a diameter of 6 mm or others - the main thing is to take the hoses.
One 10 cm long, the second 20-50, depending on the size of the receiver, more details.
Automotive fuel filters. One gasoline, and one diesel.
Manometer (optional).
Epoxy resin if a plastic receiver is used.
A piece of wooden board (base). The size depends on the size of the receiver and the motor. They should be placed on the board nearby.
Steel tape or wire. Need to secure the receiver.
Self-tapping screws.

Instruments:

Acute knife
Screwdriver
Drill
Pliers.
Pilochka for metal (optional).

How to make a compressor with your own hands

Now directly about how to make a compressor with your own hands.

From the compressor from the refrigerator, three tubes are coming out: two open and one short, sealed. Turn on the compressor into the socket and swipe near the outputs of the tube. The one from which the air blows will be output, and the one that retracts the input. Remember, where, and turn off the compressor from the socket. Metal sawmill cut two tubes, leaving 10 cm or more to be conveniently connecting hoses. You can bite the pliers, but you need to follow, so that the sawdresses do not get inside the tubes. Next, the compressor on the blackboard, screwing the legs with self-draws (you can use bolts, so reliable). Important: Breeping compressor in the same position in which it was fastened in the refrigerator. The fact is that the start relay on the motor works at the expense of the gravity forces, there is an arrow pointing up on the relay housing. Pluging the compressor, go to the receiver.

We make a receiver. Option If you have plastic containers. Drills in the lid two holes under our tubes. Insert them there, as shown in the figure, and the crepim epoxy resin. We leave the ends with a length of 2-4 cm. Now the length of the tubes is now. Short (10 cm) will be a day off. The second will be input, we do it as much as possible so that it does not take some centimeters to the bottom of the receiver. This is done in order to separate the input and outlet openings within the receiver for greater mixing air.

If you have an iron receiver, do the same, but not glue tubes, but we solder or weld. You can also hold nuts, and then twist the fittings for hoses.

Pressure gauge can only be installed in the metal receiver. To do this, drill in any convenient location on the receiver hole and solder a pressure gauge. More preferred option: We weld the nut on the hole and tighten the pressure gauge in the nut. So in case of failure of the pressure gauge, you are easily replaced.

Now we take a segment of the hose (10 cm) and put it on a gasoline filter. If you use hoses for gasoline, there should be no problems if you use polyvinyl tubes, then it is possible to heat it with a match or hold in boiling water that it takes it to the filter fitting. The second end of the hose put on the compressor inlet tube. This input filter is needed to filter dust. Here on the connections, the use of clamps is not necessarily, since there are no pressure here.

We take the second segment of the hose and connect it the outlet tube on the compressor with the inlet on the receiver. In places of compound, we put the clamps.

Now the third segment of the hose (10 cm) is put on with one end to the receiver's output tube, and the second end is dressed on a diesel filter. We wear clamps. On filters (diesel and gasoline), the arrow indicates the correct direction of movement through the air filter. Connect both filters correctly. The diesel filter at the outlet is needed to filter water from the air.

For the emerging diesel filter fitting, we wear our working hose running directly to the airbrush, a pulverizer, etc.

On the bottom side of the boards, we screw the rubber legs or glue felt gaskets for furniture. If this is not done, the compressor when working can scratch the floor - it vibrates. The level of vibration and noise depend on the model of the refrigerator compressor. Motors from imported refrigerators are almost not heard, Soviet also quiet, but there are exceptions.

The pressure generated also depends on the model. Ancient motors are more powerful. Most Soviet compressors are able to pump up pressure up to 2-2.5 bar. The compressor in the photo creates pressure of 3.5 bar.

Maintenance of the homemade compressor from the refrigerator

The compressor maintenance is to regularly change both filters and merge the gathered oil in the receiver. But the main factor affecting the service life of the compressor is the frequency of oil replacement. The first time it is better to change it before assembling the compressor. On the motor there is a third sealed tube. We cut off from it the walled end and drain the oil from it, turning the motor. Paws around the glass of oil. Now the syringe through the same tube pour fresh engine oil, slightly more than the amount that was merged.

After noting the drain tube, tick the bolt in it with a suitable size. Upon the next oil replacement, simply unscrew the bolt.

The idea of \u200b\u200bmaking an air compressor to work with a refrigerator-based airbrush (hereinafter referred to as the text "device") caught fire for a long time, but before the embodiment I went to life about about a year.

The idea is attracting the fact that this device gives a low noise level (noise at the level of the ordinary refrigerator), allowing to work late in the evening (early at night), since the use of an oil-free Chinese compressor giving 94 dB of noise, somehow began to strain.

First of all, the compressor was required to embody the idea. This unit was acquired from hand in the work of the Biryuska Work Refrigerator. But then it turned out that the refrigerator itself is greater than the one that stands in the country. Therefore, "re-acquired" went to the country, and the compressor unit itself was ruthlessly learned from the "country". Here it is necessary to add that the compressor to the refrigerator was attached by pendant on the springs to the rigid plate, so I decided to save this design and apply entirely when making the device.

Then the old fire extinguisher OU-5 was found in the garage, which was subsequently by the receiver.
It was conceptually assumed that this device would be stationary, so I decided to make a rigid spatial design from the corners (whom the required amount was created in the dacha).

With such a set of basic technical requirements and began the manufacture of the device. The length of the device was determined by the size of the carrier plate compressor. The width appeared arbitrarily taking into account the placement of the receiver, compressor and the rest of the body.
Device Scheme Common: Compressor, Filter, Check Valve, Receiver, Pressure Relay, Pressure Regulator, Filter, Quick Connection.
After stripping the corners from rust and dirt, they were welded whether the household welding in the country is more appropriate. After I made a frame, I tried the receiver and outlined the air inlet duct point and the condensate drain point.

He drilled in the receiver two holes with a diameter of 9.00 mm and welded a wagon with a thread 1/2 ". Then something came about how the receiver would be placed and welded to fasten his support. The receiver posted at an angle of 5-10 degrees to accumulate condensate in one place. The same has done for fastening the compressor. As a result, I got very heavy (about 25 kg together with the compressor and the receiver) and a powerful design. But this turned out its plus - this is a complete lack of vibration, both on the case and on the concrete floor, where it costs.

Replaced the oil in the compressor, especially without baying the bay of 250 gr. Lukoil semi-synthetic 10 W-40. To replace, carefully opened the third (oil) tube in the compressor. Through it merged and honey hung through it. syringe (20 ml). In the tube twisted the self-sealant. Oil flooded 300 ml.
The receiver fastened with two stripes cut out of roofing iron trimming. As a gasket, pieces of watering hose cramped along.
Then the queue reached the automation and air supply system. The native tee (separator) from the fire extinguisher decided not to throw away, especially since a conical thread is used in the fire extinguisher. After breaking the tee and removing from it the shut-off valve, the hole of the valve rod blocked the bolt, having pre-cutting the thread.
Now two "live" holes remained in the tee - from the safety valve and the CO2 sprayer tube. On the fitting of the safety valve (removing it naturally), the pressure relay, such as RDM-5, was very easily screwed. But with a hole under the tube, the sprayer had to be glared. No full-time pipe thread approached this hole, therefore, by overwhelming all the possible options, I had to go to the taksopark. For 200 rubles, Tokar made an adapter from steel blanks under the standard pipe thread 1/2 ". Well, then everything flowed like" by oil ". Half a day search in stores and necessary adapters, tees, pressure regulator, pressure gauge, check valve, automotive Gasoline filters (VAZ 06, 09), and a filter of fine air purification, etc. Pressure gauge bought with a "distinct" scale to visually easier to control the availability of air in the receiver. It should be noted that the pressure switch on the passport is provided for water work So I decided to progress and disobey the relay, the working chamber was put on the sealant. Just in case. The frame painted the oil paint, which was at hand.

On the assembly of the device in the amount of two hours. All threaded compounds connected with the help of a plumbing thread "Tangit-Uninfield". Describe what is screwed to and in which sequence does not make sense, because Each device in manufacturing individually and assembly algorithm collecting determines itself. Pressure relay adjusted to shutdown at 3.5 atm., Inclusion of 1.5 atm. No matter how tried to reduce the value of the boundaries of the setpoint - nothing happened.

After the assembly began to the oppression. Here I was waiting for the first disappointment. The pressure in the receiver decreased by about 0.5 kgf / cm2 per minute. By washing, I found leakage. It turned out that "etching" from under the fittings, welded to the receiver (however, a welder from me is not professional). The exit was found immediately - cold welding. After applying and excerpts during the day I tried again. Holds pressure. HOORAY. But still there is a leak from the pressure regulator. "Leaves" about 0.1 kgf / cm2 in 20 minutes. I thought and decided more device not to "treat", since this loss of air can be neglected. Such pressure losses during painting are not fundamental for me.

The test painting showed that there are no oils in the air, paint to fall smoothly, both acrylic and enamel. And the most important thing is silence when the device is working. Q.E.D.

The new device organically sod under the table in the workshop. After a couple of days, test trials decided to check the presence of condensate in the receiver. When opening a ball crane, from there with a whistle, grams of 20 oils spun. It was the second disappointment. He thought and went to read literature. After reading different storts and reflected logically, I understood one thing that the compressor oil will sleep anyway, because in the refrigerator, the system is closed, and in my device - no. Therefore, I will periodically pour oil into it, approximately in the proportions "how many spit, so much and poured." And people write that the compressor on the engine oil will not last long. Well, wait and see.
A new device strangled

When the refrigerator fails, a person prefers to immediately send it to a landfill, and acquire a new unit for freezing products. The compressor from the refrigerator still should be left, because this part of the household appliance can be a lot of useful to a person. You can use the compressor from the refrigerator to pump tires for pumping water and even in airbrushing this tool is useful. But before talking about the nuances of using the aggregate, it still needs to be mined. To do this, you need to find an aggregate similar to a large black bowler at the bottom of the refrigerator. Next, you should unscrew the bolts and nuts, with which the item is attached to the refrigerator itself. With the help of the hacksaw, the compressor must be sprinkled from the refrigerator radiator. Now it remains only to check the functionality of the compressor. It is connected to the network for this, and if the item begins to make characteristic sounds, it means it works.

The extracted compressor from the refrigerator can be used to fix other large household appliances. For example, if a person has emerged a compressor on another refrigerator, the item can safely replace and continue the use of technology. However, often craftsmen find completely different spheres for the use of this unit. For example, a very often compressor is used in garages for pumping tires and pumping oil. But before the start of its application, you will have to install a special receiver. The receiver itself is required for the unit to work normally and smoothly, not too overloading the network. Also, this nuance should be observed that in the process of work, the compressor did not spray oil. The receiver should be secured on the compressor tubes, additionally checking the strength of the connection. After that, you can move to the operation of the compressor for your own purposes.

The old refrigerator compressor finds the widest range of applications in the garage. It has already been mentioned above that the technique can be used to swing tires due to the fact that the compressor itself is able to distinguish air. To pump tires, the unit needs only to be included in the outlet and attach to the bus. But not more than two tires will be produced in this way, since the compressor from the refrigerator works quite slowly, but it may noticeably overload the network. The compressor from the refrigerator has sufficient pressure for pumping automotive tires. For the purpose of pumping the bike wheel, you can use, for example, the part from the air conditioner. Another scope of application of the compressor in the garage is for pumping out of excess oil. Here you need to unscrew the oil filter, and with the help of the compressor to pump the required amount of oil. The process itself usually takes no more than 2-3 minutes, but over the oil level you need to monitor all the time.

One of the most popular options for using an old compressor is for airbrushing purposes. The art of airbrushing implies the use of a special apparatus for drawing a picture within the framework of special equipment. The compressor will just become such an aggregate, and quite powerful. To build an airbrush, you will need an old compressor, a receiver, a rubber tube, a thin cleaning filters, a chlorvinyl tube, fastening clamps and furniture screws. Before starting an airbrush, it is necessary to replace the oil in the compressor on a simple road, as it will have a positive effect on the work of the technique. Next, connect the receiver, connect the start relay to the compressor and the refueling tube. The gasoline filter should be fixed on the compressor itself, diesel on the receiver. By connecting the entire design using existing tubes, you can connect an airbrush to the network and use it in order to create original drawings.

Effectively use the old compressor can also pump water from the water supply system. For example, when replacing or repairing water supply, it is often difficult to pump out the entire liquid from the pipes, and this complicates all further actions. That is why specialists recommend using a compressor. To create a water pumping system, you will need a simple, glass bottle, two sucking tubes and liquid in a special container. One sucking tube must be connected to the compressor, leaving the second end in the bottle. The bottle itself is then recommended to close to create a vacuum. The second tube should also be left into the bottle, and it is left to leave it in water tanks. In essence, the unit for pumping water is ready, and it can be started to use. With the help of another opening on the compressor, you can safely pump liquid from the water supply system, it is noticeable for yourself to repair the repair process.

All listed ways to use the compressor are real, but, of course, to resort to them only in the presence of special technical knowledge. If the man himself does not mean himself, as the compressor looks like, and how to create an aggregate to pump tires, then it is better not to work with this detail of the refrigerator. On the Internet, you can find a lot of instructions for converting the compressor in a wide variety of purposes, and it is very important to take into account the scope of the assembly of the unit. Also when working with it, it is necessary to follow safety, tracking and that the network is not under too much voltage. Old and rusty compressor can still serve a person for a long time. That is why if the owner of the refrigerator does not plan it to use it, it is better to immediately share the technique for disposal, where the old compressor will definitely be selected in various fields.

Often, the old unused refrigerator remains a completely efficient compressor. It can be slightly upgraded to get a full-fledged installation suitable for use for various purposes - most often they are used for painting, pumping automotive tires, performing airbrushing or feeding pneumatic devices. Consider how to make a compressor with your own hands from the old refrigerator.

Details and tools required for the manufacture of compressor

To make the compressor from the refrigerator with their own hands, the following tools will be required:

Welding machine (inverter).
Electrode, screwdriver.
Bormashina, engraving mini drill with a set of cutters.
Brush with a metal pile to remove rust.
Passatia, wrench set, adjustable key.

From materials need to cook:

Plates made of steel 2-3 mm thick 3-4 cm wide.
Two supports on wheels.
Adapter by 1/4 inches.
Deaf Halfish coupling with internal thread.
Check valve and connector for it.
Two copper shelter couplings connector under the copper tube.
Clamping bolts, nuts, other fasteners, fum-tape.

During the work, it may be necessary to use other tools or materials. So, instead of a propane cylinder, a housing from a fire extinguisher or a ready-made automotive receiver can be used. Some masters offer to install plastic containers, from which it should be refrained, since the compressor from refrigerators can create high pressure capable of breaking such a receiver.

Refrigerator compressor manufacturing process

The technology of manufacturing a self-made compressor from the refrigerator consists of several stages.

Receiver

To make a compressor from the refrigerator, you need a high-quality receiver. For this purpose, a metal container with a hermetically exit is an empty gas cylinder for 11 liters. First of all, it is necessary to get rid of the remnants of the gas mixture in the cylinder, for which it is peeling a pretty water from the inside. Then, 1/4 inches adapter is applied to the opening in the end and the jack with maximum sealance of the seam is caused. The finished adapter should be drowning in the bolt.

In the lower part of the cylinder welded methods are installed with wheels with wheels. For stability, the support is welded in the upper part, providing horizontal. The result is a balloon based on three points (two wheels and a support bracket), equipped with an outlet fitting.

Installation of compressor

The next step is to install the compressor on the receiver. To do this, you will need to welcome the two mounting brackets on top of the horizontally located cylinder. The distance between them corresponds to the position of the mounting holes on the compressor, which will be recorded on the brackets the clamping bolts. To ensure silent work, which is distinguished by homemade compressor installations made from old refrigerators, rubber gaskets should be installed between the body of the device and the brackets.

Important! Before installing the compressor, it is necessary to replace the oil inside it, to another, neutral to the action of air (Lukoil 10 W-40 is suitable). The oil replacement is produced through a walled removal, which then should be selected again. To eliminate oil from entering the air, you must install the filter at the output from the compressor.

Check valve and adapter to equipment

Installation of check valves - scheme

The next stage of the manufacturer of the self-made compressor is the installation of the check valve and adapter to attach the adjustment equipment. To do this, you will need to drill the corresponding holes in the receiver housing - under the check valve it is more convenient to arrange on the side, and under the equipment - from above, close to the compressor.

A coupling with internal thread is boiled in the receiver's housing, the same as that of the check valve. It is necessary to drown out a hole for resetting the pressure, since such a device is available in the control instrument block taken from the old refrigerator.

The hole is faded with a screw, under which a thread is preloaded. The screw is winding fum-ribbon and tightly screwed into the hole. Then the check valve is connected to the compressor tap, for which the copper semi-leaf coupling connector is used. The ends of the tubes with the pre-inserted parts of the coupling are flared, after which the coupling is tightly connected.

Installation of adjusting equipment

It is best to use adjustment equipment that was installed on the refrigerator complete with a compressor. They are optimally suitable for each other. The adjustment assembly usually includes pressure switch, pressure relief valves, pressure gauges and several regulators.

First set the pressure relay. This is a black box with a pressure gauge, it is joined through an extension with an external thread to the exit in the top of the balloon next to the compressor. Then all other parts of the assembly join the relay.

Adjustment equipment on the compressor

Connecting electricians

The wires of the compressor feed from the refrigerator are connected to the corresponding pressure relay contacts. To do this, remove the lid with the relay, after which the contacts will be visible. The three-core compressor wire (with ground) connects to the appropriate contacts (they are marked with a special label), in a similar way the power wire is connected, equipped with a fork for the power outlet. The strength of the contact connection is checked, the relay cover is installed in place.

Checking the work of the homemade compressor

After connecting all parts and connecting the power wiring, a trial start and configuring the operation mode is performed. The compressor is included in the network, using the adjustment assembly, the mode of switching on / off the device is configured when a set of defined pressure.

It is not recommended to immediately install high values, because it can be detected by the grinding of the welded joint on some of the fittings. Found flaws are subject to elimination, for which the device is disconnected from the network, the pressure typed during the trial start is reset, the detected flaws are eliminated. After that, the device is again connected to the network and runs into operation.

No need to once again talk about what a compressor is needed, because it is so clear. But from the refrigerator do it yourself not to do with everyone under power. Nevertheless, stamp patience, the necessary tool and theoretical knowledge, with this task you can cope, and quite quickly. You can use such equipment together with an airbrush, spray gun, etc. tool. The key features are that the work is almost silent, and the dimensions are small. But the pressure of such a compressor creates very good.

Why homemade, not professional?

You probably already know the answer to this question. Often the case in price. Professional compressors have a high price. And if you have an old fridge, which costs without a case, then why not take yourself for a few hours and do not make the compressor yourself. As for the design, it differs, but not very. Purchased models have an electric motor that transmits work through belt transmission. In our case, the electric motor and the working chamber will be in one case, but there is no belt transmission.

Less in homemade product and automation. Although the protection against overheating must be installed. Such a relay will save your motor from high temperatures and prevents breakdown. As for lubrication, professional compressors can be dry, that is, not to have lubricants. Such models work at the expense of graphite rings. In our case, the lubricant will be much, which directly affects the durability of the equipment.

It is worth noting that the homemade compressor from the refrigerator do it yourself is not so difficult. But it is necessary to understand that it takes attention to the details. In any case, if you all succeed, then at the output you will have a functional station that you can adjust how you want and component as it is convenient for you. All this, unfortunately, cannot be done with purchased equipment.

Dismantling works

Before using the compressor, it must be removed from the refrigerator and appropriately equipped. But about it a little later. Now actually about how to make dismantling work. There is nothing difficult here. You will need a small set of tools: pliers, two screwdrivers (flat and cross), a couple of cape keys. Probably everyone knows where the compressor is located. Usually it is the bottom rear of the refrigerator.

Now you can start withdrawal. You will see copper tubes that lead to the cooling system. With the help of pliers, they must be bought off. Preferably with maximum vacation. In the future, you can use them for your own purposes. It is worth drawing your attention to what you need to bite the tubes, and not try to saw them using a file. "Why?" - you ask. It's simple, when sawing, a small chip is necessarily formed, which in one or another size falls into the compressor, which can lead to a deterioration of its technical condition up to breakage.

On this work is not completed, we need to remove an equally responsible element - a starting relay. It is usually white or black small boxes with wiring and coming out of it. Gently need to unscrew the mounts and bite the wires leading to the fork. Put in advance where the relay is top, and where the bottom. It can be indicated on the case, check. We need in order to remove the compressor carcass. So we removed the compressor from the refrigerator with their own hands. Another point, take all the fasteners with you, they will use you.

Check the performance of equipment

First of all, after removal, make sure that the compressor is not "died" and can be used for its own purposes. To do this, turn the copper tubes with a pliers. This is done in order to go through them freely and air. In the next step, we need to put a launch relay in such a position in which it was even before removal. It is extremely important. The fact is that the relay works on the principle of heating plates and earthly attraction. Invalid orientation will lead to his breakdown. It can even burn the compressor winding that is not good.

There are incoming wires on the relay. They need to fasten the wire with a fork. The location of the connection, to avoid damage to the current, must be tightened with a tape. After that, you can stick the plug into the outlet. If the compressor is taurated quietly, and air goes from the tube, it means that you all have done correctly and the equipment can be used. At this stage, it is recommended to mark the tubes to know which air leaves, and what it comes to. If, during operation, problems appeared, say, the compressor does not turn on or turns off after a while, then you will have to perform a relay call and find a weak link. This procedure requires minimal knowledge of electrical chains and electrical engineering as a whole.

Materials required for work

Before making a compressor from the refrigerator, you need to get all necessary for work. First, this is a compressor. We have already figured out how to remove the engine (compressor) from the refrigerator, so it should be at your hand. By the way, various compressors are installed on different models of refrigeration technology. Usually they are a cylindrical form product or so-called pot.

In order to make a high-quality compressor, which would fulfill its purpose 100%, you must get a receiver. In fact, this is a container into which the engine from the refrigerator will pump air. In principle, there are no certain requirements for the receiving. An old empty fire extinguisher is suitable, a receiver with a truck. The volume can be different - from 3 liters and more. Also before making a compressor from the refrigerator, you need to find suitable hoses. The length of two of them should be 10 cm and more, the latter should be at least 50-60 cm. It is very convenient to take automotive hoses. The fact is that they will be attached to filters, and their size is excellent for these purposes.

As for consumables, these are two filters - gasoline and diesel, clamps, wire, epoxy resin, pressure gauge. As for the tool, it is every host in the workshop. We need drill, knife, screwdriver and pliers. After you all collected in a bunch, you can start working.

From the refrigerator: step by step instructions

Most output compressors have three copper tubes. Two of them are open, those that you bought off pliers, and one common. Usually it is the shortest. Accordingly, the tube from which air blows is the output, and the one that sucks is the entrance. We still do not touch the third, but a little later we will deal with what she is and what to do with it. So, after checking out and input, make the appropriate marks and disconnect the compressor from the network. Next, we take a pre-prepared board. She will be our basis. With the help of self-tapping screws, secure the compressor to the board. The tubes before the connection must be additionally processed. It is desirable not to use a metal pylon, it is better to take pliers.

One important point: the compressor must be based on exactly the same way as it was installed on the refrigerator. Installation of sideways or upside down is invalid. This is due to the launch relay, which works at the expense of gravity forces. Our compressor is not yet made from the refrigerator. Now we need to make a receiver. A plastic container is suitable. In its upper part, two holes under the tube of the corresponding diameter are drilled. Then we insert them there and pour it all this epoxy resin for sealing. One of the tubes (input) should not get to the bottom of the receiver a couple of centimeters. A short tube (output) runs about 10 cm. Such manipulations are needed for more convenient mixing air.

Iron Receiver

"How to make a refrigerator?" - you ask. Yes, it is very simple, for this you need to use the instruction described above. But there is one thing, for such purposes it is best to take the iron receiver. There is no special difference between plastic and metal, but only on the iron receiver we can install a pressure gauge. In addition, the hoses are searched or brewed, and not poured a resin. It provides better tightness of the container.

To install the pressure gauge, you must drill the opening of the corresponding diameter, install the device and squeeze this place. Although more humane would be followed by the following way. We drill a hole in a suitable place and you brew a nut into this place. Then it remains only to fasten the pressure gauge, and the case is done. In principle, there is no special difference, only the replacement of the failed manometer is much easier. After everything is done, you can mount the receiver to the base. To do this, use a steel tape or wire. In fact, we almost made the compressor from the refrigerator. There are several small details.

How to make a mini compressor: the last part of the installation

We have already passed most of the way. Now there are several strokes. For a start, we take the segment of the hose (10 cm) and put on it a gasoline filter. If you are using a car hose, there should be no problems with putting on. If the hoses are thin and the fitting are not put on, then as an option you can warm up. The free end of the hose needs to be put on the compressor's inlet. If the connections are durable, then the clamps can not be used, especially since there is practically no pressure here. It is easy to guess that the filter is necessary in order to exclude dust entering the compressor. The second segment of the hose is connected to the compressor outlet and the input receiver. There will already be great pressure, so we put the clamps. On the third hose we wear a diesel filter, and the second end insert the receiver to the outlet. The emerging fitting of the filter (diesel) joins the working hose of the pulverizer, an airbrush or other equipment. You will probably decide how to use the compressor from the refrigerator and in what purposes.

Specifications and maintenance of equipment

As for the pressure generated by the pressure compressor, it is difficult to talk about specific figures. Much depends on the model and age of the equipment. By the way, "ancient" compressors are more powerful. They are able to give about 2-3 bar. Both imported and Soviet models work almost silently, truth, there are exceptions.

As for the service, this is a rather important point if you do not want to quickly need a refrigerator compressor. It is not difficult to care for such equipment with your own hands. The main rule is that it is necessary to periodically change gasoline and diesel filters. In addition, it is desirable to merge oil accumulated in the receiver. The crucial role in the durability of the equipment plays a high frequency of oil replacement in the compressor. Do this need not how often, how much at the designated term. To merge through the work, you need to cut off a piece of the sealed tube. Remember, we mentioned about it at the very beginning of the article. Through it, the old oil merges and the new one is poured.

Should I repair the compressor?

Often the engine refrigerator fails. Oddly enough, but often there is no point in repair. But when it is in a coolness, the question is solved by its replacement. As for other cases, for example, dust hitting or burning the winding, it is better to leave without attention. Really easier and cheaper to buy a new engine. But with their own hands it makes sense. There is nothing difficult in this. Moreover, about how to shoot a compressor from the refrigerator, you already know. It is installed in the reverse order.
