The receiver for the compressor do it yourself from the fire extinguisher. How to make an air compressor with your own hands: design options. Semi-professional air supercharger

Hi friends! Are you happy car owners who have a fire extinguisher is not used for destination and is ejected after the expiration date? I wish you, and I wish you all such happiness.) In general, if you had an old fire extinguisher, do not hurry to throw it away, because it can get a great compressor from it, not inferior in power and the quality of the purchase.

To begin with, we need to release air and powder or foam from the fire extinguisher, shorter to empty it. Then we swing the head and rinse the fire extinguisher, let dry.

Now we need an adapter, a half-day tee, a sixmillimeter Christmas-tree fitting for air supply, for the release of air we take an adapter with a floor of a quarter to a quarter of an inches and from it for a quick-consuming adapter for pneumatic tool.

We will collect it all on an anaerobic sealant, it freezes very quickly and is designed for pressure up to 50 atmospheres, just what we need.

To supply the air, we will need an electro pump, you can automobile compressor, we connect it to the "Christmas tree" stacker.

Well, everything, it remains to embroider the hose for air output and the compressor is ready.

On your hands you have a working compressor, but in order to bring it to the ideal, and you can make it similar to the purchased, you can make it a pressure gauge and make a body, it is already at your discretion. I did it and that happened.

It is not necessary to buy a compressor for painting works or packed wheels - you can make it with your own hands from the used parts and knots taken from the old technology.

We will tell you about the designs that are collected from the primary materials.

In order to make a compressor from parts and used components, you need to prepare well: examine the scheme, find in the farm or buy some details. Consider several possible options for self-constructing an air compressor.

Air compressor from the details of the refrigerator and fire extinguisher

This unit works almost silently. Consider a scheme of a future design and make a list of necessary nodes and parts.

1 - tube for pouring oil; 2 - launch relay; 3 - compressor; 4 - copper tubes; 5 - hoses; 6 - diesel filter; 7 - gasoline filter; 8 - air inlet; 9 - pressure relay; 10 - Cross; 11 - Safety valve; 12 - tee; 13 - Receiver from the fire extinguisher; 14 - pressure reducer with pressure gauge; 15 - moisture meadow; 16 - Pneummatore

Required parts, materials and tools

The main elements are taken: a motor-compressor from the refrigerator (better than the production of the USSR) and a fire extinguisher's balloon that will be used as a receiver. If there is no available, then the compressor from the broken refrigerator can be searched in workshops on repair or in metal reception locations. The fire extinguisher can be purchased in the secondary market or attract familiar to finding, at work, which can be written off OKHA, OVP, OU by 10 liters. The body of the fire extinguisher must be safely emptied.

In addition, you will need:

pressure gauge (as for a pump, water heater);
diesel filter;
filter for gasoline motor;
pressure switch;
electric toggle switch;
pressure regulator (reducer) with pressure gauge;
reinforced hose;
plumbing, tees, adapters, fittings + clamps, hardware;
materials for creating a frame - metal or wooden + furniture wheels;
safety valve (for resetting overpressure);
pneumature with self-painting (for connecting, for example, to the airbrush).

Another viable receiver turned out of a car without a carless wheel. Extremely budget, although not too productive model.

Receiver from the wheel

We offer you about this experience. Watch the video from the author of the structure.

With the help of a 12 volt compressor, you can pump the tires, remove garbage and dust, blow (clean) the lattice elements, pump the balls, feed the compressed air into the crash and so on.
If the compressor is equipped with a receiver, then its operation mode will be facilitated. After all, such a container creates a supply of compressed air, which allows you to take breaks in the compressor.

At the same time, the quality of the supplied air will increase, since the receiver aligns pressure, smoothes the pulsation, cools the compressed air coming from the compressor, and the condensate collects.

Necessary accessories

Our installation will consist of two main parts: compressor and receiver - fire extinguisher housing. For the safe and reliable operation of the device, it is important that the pressure generated by the compressor (140 psi ≈ 10 Bar ≈ 10 kg / sq. Cm), there was no longer the pressure on which the fire extinguisher body is calculated (20 bar ≈ 20 kg / sq. Cm).

To create an automatic installation installation, we will need the following accessories:

shut-off node on the receiver with a system of channels with thread;
safety valve;
pressure gauge with a scale in bars;
switch-relay pressure;
valve as a ball valve;
spiral and linear hoses;
pneumatic equipment;
12 volt battery;
fittings, fittings and adapters.

To build individual nodes to a single whole, we will be needed:

keys and pliers;
drill and crimper (means for crimping wire lugs);
hacksaw and scissors;
o-rings and fum-tape;
wire knitting and tape double-sided;
a piece of plastic pipe.

Production of a receiver from fire extinguisher body for compressor 12 V

The receiver is better to choose a fire extinguisher with a large volume. In this case, its effectiveness when working in a pair with a compressor will be higher.
Next, unscrew the shut-off valve with the hose, shake out of the housing its contents (usually this substance based on ammonium phosphates, as the cheapest, but there may be other compounds).

Then we rinse the body of the fire extinguisher from the inside with clean water several times. We wipe the capacitance from the outside with a clean cloth and dried the inner volume with a hair dryer.

Receiver equipment

Before this stage of work, once again compare the characteristics of the compressor and the former fire extinguisher body, and we are convinced that our receiver in all parameters will correspond to the capabilities of the compressor.

We screw the shut-off node in the neck of the metal container with the central channel and four side drills with carvings.

In one of the side channels we screw the safety valve, adjusting it to a smaller opening pressure.

Of the two available manometers, choose the one that is touched by the bar pressure units, and also we also screw it into another side channel on the shut-off site.

In the two remaining channels, we screw the adapter and the switch-switch pressure - the main element of the automation system, including the compressor when the pressure in the receiver will become less worker.

From above to the shut-off node we screw the ball valve of the compressed air from the receiver or its overlap.

Next, using a set of rubber rings, fum-ribbons and keys, we seal and strengthen the location of the connections of all items with a shut-off knot and the last - with the body of the future receiver.

It remains to screw onto the ball valve, also using a sealing ring and a fum-tape, an adapter for installing a spiral hose, on the other end of which will be attached through the same adapter to a tool operating from compressed air (we have a pneumatic equipment).

Compressor strapping

Pre-check its performance by connecting to a 12 volt battery, and we make sure that everything is in order with him.
At the outlet compressor fitting, we put on the hose adapter. Seal with a fum-ribbon and firmly tighten the hex connector with keys.

We establish a compressor to the receiver to the place where it will be fixed later. Cut off the hose at the exit, leaving a small process that we wear a plastic rectangular fitting. It is necessary to give the desired direction of the hose, which will come out of it, and connect with the adapter on the receiver. Between the two last details in the hose, the hex connector is cut - it is the same check valve.

Installing the compressor on the receiver

We stick on the supporting surfaces of the base of the compressor strips of two-way tape. This will pre-fix nodes relative to each other, and further facilitate the strength of the connection.
Then, with the help of pliers and knitting wire, which we skip through holes at the base, firmly screw the compressor to the receiver.

Production of the reference part of the installation

To do this, you will need a piece of plastic tube, in size comparable to the outer diameter of the receiver. With the help of the knob, we cut three rings of equal width from the pipe.

In two rings we make a cross-section so that they can be put on the receiver. The third ring is cut into two equal parts. They, in fact, will be the "legs" of our installation.

In two rings in diametrically opposite cut points drill holes with a drill. Doing the same in half rings on their center.
We connect the pairs of rings with semirings through screws and drills, turning hardware from the side of the split complete ring.
On the inner part of the split rings, covering the screws of the screws, we glue the bilateral scotch strip to fix the rings on the receiver case below.

Install the rings on the receiver, squeezing them down. For the strength of fixing the rings on the surface of the receiver for each end of the ring, ranging from the cut and below, also glue through the strip.

Pressure selection in the receiver and relay setup

After connecting the hoses and turn on the compressor, check the increase in pressure in the receiver on the pressure gauge and the operation of the installation using a pneumatic system with a power off. We water the pressure in the receiver using a safety valve, pulling the ring on the rod.

We cut one living wire from the compressor and connect its ends to the pressure relay using tips and a crimper. We turn on the compressor again and make sure that the pressure in the receiver is growing.

Make a small compressor for the airbrush is very simple. For these purposes, you will need a small air compressor, as well as the container in which air under pressure will accumulate, in other words, the receiver. As a compressor, the author for this homemade used the compressor from the refrigerator. As for the receiver, the OKH-10 fire extinguisher has perfectly approached for these purposes, the volume of which was 10.5 liters in the measurement instead of the declared 8.5 liters of fire extinguisher for almost free. The author of the homemade cost no more than 2000 rubles.

Materials and tools for homemade:
- fire extinguisher OKH-10 or other suitable;
- PM5 pressure switch;
- two filters of the moisture separator;
- one fuel filter;
- reinforced pvc hose (internal diameter 10 mm);
- gearbox with manometer;
- pressure gauge for measuring pressure inside the receiver;
- FUM tape;
- Pliers, keys and other tools.

The process of manufacturing an airbrush:

Step one. Preparation of fire extinguisher
First of all, you need to free the fire extinguisher from the contents. It must be done in the open area.
Now it will be an empty cylinder, you need to fasten it to the base. This process will not be for anything of great work.
From the lid you need to extract all the contents, including from the fire extinguisher. As a result, a cylinder and cover should remain.

Step second. Assembly selfiem
In the cast-iron lid, you need to cut the pipe thread for 1/4 inches. You need to hide the FMU tape for tightness to a wide cylinder thread for tightness, as well as make a rubber gasket if native is lost or corrupted. It can be made of a car chamber. Well, then the cast-iron cover is screwed.

Then in the opening of the cover, the adapter is 1/4 new per 1 / 2n-inch. Then you need to screw 1/2 inches cross. Of course, all connections need to be sealed using the FUM tape.

In the adapter from 1 / 2np - 1 / 4nc, you must screw the pressure switch, also on the side of the adapter 1 / 2NP-1 / 2NR.

The author screws the side of the tee.

Subsequently, a gearbox is screwed down to the tee using an adapter 1 / 2NP-1 / 4VR, it has a thread 1 / 4n.

On the other hand, again through the adapter 1 / 2NP-1 / 4VN, the pressure gauge is screwed, it is also a thread 1 / 4n. From the opposite side of the cylinder, you must screw the valve, with the help of it from the cylinder will go down the air. The valve has a thread 1 / 2n.

A filter water separator must be connected to the gear separator, a thread is used 1 / 4n. It is important to install a filter at the right angle. The drain hole should be at the lowest point.

Then you need to make a line of another filter. On the part of the incoming hole, there is a fitting 1/2 rev., connected via an adapter 1 / 2np - 1/4 rev. It must be screwed onto the filter, which has a thread 1 / 4n. What should turn out in the end, you can see in the photo.

A 1 / 4NP-1 / 2NP adapter should be screwed into the opening of the filter 1/4), and the tee is then screwed to it. On the one hand, the tee is muffled with a plug 1 / 2np, and on the opposite side the fitting 1 / 2np is screwed.

Step Three. Final stage assembly
Now you need to take the reinforced hose and turn it on the fitting, which comes out of the fire extinguisher. The hose is fixed with the help of a clamp. On the other hand, the fitting is inserted into the hose from the filter, it is also attached to the clamp.

After that, the hose is connected again to the filter and connects to the compressor tube. Everything is tightened by clamps.

At the final stage, a similar fitting should be screwed up at the outlet opening of the filter 1/4 rev. A silicone tube is perfectly put on it, which is not even needed to fix the clamp. Well, the other end is connected directly to the airbrush.

Due to the fact that the pressure is small for the gearbox, if compared with the receiver, the tube withstands it without any problems.
