not need once again to talk about why we need the compressor, because it is so clear.But homemade compressor of the refrigerator with their own hands to make not everyone's strength.However, zapasshis patience necessary tools and theoretical knowledge, this task can be dealt with, and quickly.You can use such equipment with the airbrush, spray gun, etc.tool.Key features of it is that the work is almost silent, and the dimensions are small.But the pressure of a compressor creates very good.
Why is homemade, not a professional?
You probably already know the answer to this question.Often the case in the price.Professional compressors have a high price.And if you have an old refrigerator that is not the case, then why not take yourself for a few hours and did not make the compressor itself.As for design, it is different, but not much.Purchased models have an electric motor that transmits a job through a belt transmission.In this case, the motor and the working chamber will be in the same housing, but no belt transmission.
least in a homemade product and automation.While that's overheating protection must be installed.This releshka save your engine from high temperatures and prevent breakage.As to lubrication, the professional compressors may be dry, that is have no lubrication.These models work by graphite rings.In our case, the lubricant will be many that directly affect the durability of the equipment.
worth noting that homemade compressor of the refrigerator with their hands do not so difficult.But you must understand that there is attention to detail is required.In any case, if you succeed, then at the exit you will have a functional station, which can be adjusted as you like and link the way you want.All this, unfortunately, you can not do with the purchased equipment.
Disassembly
Before using the compressor, it is necessary to remove from the refrigerator and suitably equipped.But more about that later.Who is actually about how to execute dismantling works.Nothing complicated here.You will need a small set of tools: pliers, two screwdrivers (flat and Phillips), a pair of spanner.Probably everyone knows where the compressor is located.This is usually the lower back of the refrigerator.
Now you're ready for removal.You will see the copper tubes that lead to the cooling system.Using pliers, they must bite.Preferably with a maximum release.In the future you will be able to use them for their own purposes.It is necessary to draw your attention to what you need to bite the tube, rather than trying to cut them with a file."Why?"- You ask.Quite simply, when cutting is required to form small chips, which in a certain amount enters the compressor, which may lead to a deterioration of its technical condition until breakage.
This work is not finished, we need to remove the least responsible element - starting relay.This is usually a small white or black boxes of incoming and outgoing wires from it.Carefully unscrew the mounting and bite wires leading to the fork.In advance, mark where the top of the relay, and where the bottom.It can be stated on the package, check.Spanner needed to remove the carcass of the compressor.So we removed the compressor of the refrigerator with their own hands.Another point to take away all of the fasteners with you, they will be useful.
Verifies equipment
first step after removing the need to ensure that the compressor is not "dead" and you can use it for their own purposes.To do this, flatten the copper tube using pliers.This is done so that through them freely leaving and entering the air.In the next step we need to put the starter switch in this position, in which it was before removal.This is extremely important.The fact that the relay works on the principle of heating plates and due to gravity.Wrong orientation will cause it to malfunction.Even winding can burn the compressor, which is not good.
relay wires are included.They need to fasten the wire with a fork.The junction, in order to avoid electric shock, you must tighten the tape.Then you can stick a fork into a socket.If the compressor is currently rumbles quietly and out of the tube is the air, so you have done everything correctly and the equipment can be used.At this stage, it is recommended to mark the tube in order to know some of the air out, and what is included.If during operation there were problems, for example, the compressor is not switched on or off after a while, you have to execute a dial switch and find the weak link.This procedure requires a minimum of knowledge of electrical circuits and electronics in general.
necessary materials
before a compressor of the refrigerator, you need to get all the necessary work.Firstly, this compressor.We've already figured out how to remove the motor (compressor) with the refrigerator, so it must be right at your fingertips.By the way, on different models of refrigeration compressors installed different.Typically, they are the product of a cylindrical shape, or so-called pot.
In order to produce high-quality compressor, which would perform its function at 100%, you must acquire a receiver.In fact, it is the capacity in which the engine with cooler air will be pumped.In principle, there is some specific requirements for the receiver.Suitable old empty fire extinguisher tank with truck.The volume may be different - from 3 liters or more.Also, before a compressor of a refrigerator, to find a suitable hose.The length of the two of them must be 10 cm or more, the latter must be at least 50-60 cm. It is very convenient to take automotive hoses.The fact that they will be attached to the filters, and the size of their excellent for this purpose.
As for consumables, this two filters - gasoline and diesel, clamps, wire, epoxy resin, a pressure gauge.With regard to the instrument, it exists in every host in the studio.We need a drill, knife, screwdriver and pliers.Once you have gathered all of this together, you can begin to perform work.
Compressor with their hands from the refrigerator: step by step instructions
Most compressor outlet has three copper tube.Two of them are open, those that you bit off a pair of pliers and one sealed.Usually it is the shortest.Accordingly, the tube from which the air blowing - off, and the one that sucks - entrance.The third is not concerned, but a little later, we understand, for what it is and what to do with it.So, after checking the entry and exit make the appropriate mark and disconnect the compressor from the mains.Then take the prepared board.It will be our foundation.With the help of screws fasten the compressor to the board.Before connecting tubes must be further processed.It is advisable not to use a saw blade for metal, better take the pliers.
One important point: the compressor must be fixed to the basis of exactly the same as it was installed on the refrigerator.Installation sideways or upside down is not allowed.This is due to a familiar starting relay, which is operated by the forces of gravity.Our compressor with their hands out of the refrigerator has not been made.Now we need to make the receiver.Suitable plastic container.In its upper part two drill holes corresponding to the tube diameter.Then insert them in there and fill it all with epoxy resin for sealing.One of the tubes (input) should not get to the bottom of the receiver a few centimeters.A short tube (output) run about 10 cm. Such manipulations need for better air mixing.
receiver Iron
"How to make a compressor for painting out of the fridge?"- You ask.It's very simple to do this, use the instructions above.But there is one but, for such purposes, it is best to take iron receiver.Between plastic and metal is not much of a difference, but only on the iron receiver, we can install a pressure gauge.In addition, the hoses are soldered or welded, but not filled with resin.This provides better airtightness of the container.
to install a pressure gauge, it is necessary to drill a hole of appropriate diameter, to install the device and solder this place.Although it would be more humane to the following way.We drilled a hole in the right place and this place brew nut.Then just have to fasten the pressure gauge, and it's done.In fact, not much difference, only the replacement of faulty pressure gauge is made significantly easier.Once done, you can attach the receiver to the base.For this use the steel strip or wire.In fact, the compressor of the refrigerator with their own hands, we are almost done.Only a few small details.
How to make a mini-compressor: the last part of the installation
Most of the way we have already passed.Now we have a few strokes.For starters take a piece of hose (10 cm) and put on it the fuel filter.If you are using the car hose, the problems with putting on should arise.If the hoses are thin and on the union not to wear, how they can be an option to heat.The free end of the hose should be put on an inlet compressor.If a strong connection, the clamps may not be used, especially since there is almost no pressure.It is not hard to guess that the filter is required to eliminate the ingress of dust into the compressor.The second segment of the hose connected to the outlet of the compressor and the input of the receiver.There will be a lot of pressure, so put the clamps.On the third hose put on the diesel filter and the other end inserted into the outlet receiver.Exhaust fitting Filter (Diesel) is attached to a working hose sprayer, airbrush or other equipment.You probably do, and decide how to use the compressor from the refrigerator and for what purposes.
Specifications and equipment maintenance
As for the pressure generated by the compressor, then here is difficult to talk about specific numbers.Much depends on the model and equipment age.Incidentally, the "old" more powerful compressors.They are able to give the order of 2-3 bar.Both imported and Soviet models work virtually silently, though there are exceptions.
As for service, it is quite important if you want to quickly repair the compressor of the refrigerator needed.The hands to take care of such equipment is not difficult.The main rule is that you need to periodically change the gasoline and diesel filters.In addition, it is advisable to drain accumulated in the oil reservoir.A decisive role in the longevity of the equipment plays a high frequency of oil change in the compressor.This should be done not as often as the appointed time.To merge the refinement, it is necessary to cut off a piece of a sealed tube.Remember, we mentioned about it at the very beginning of the article.Through it, the old oil is drained and filled with new.
Needless to repair the compressor?
often the engine cooler fails.Strangely enough, but often there is no sense to repair.But when the matter hladgene, the question is decided by his replacement.As for other cases, for example, dust or combustion inside the coil, it is better to ignore.Really it is easier and cheaper to buy a new engine.But the replacement of the compressor of the refrigerator with their hands makes sense.This is difficult to nothing.Especially because of how to remove the compressor from the refrigerator, you already know.It is installed in reverse order.What matters is that the installation was performed correctly.That is, the joints must be sealed tubes and wires - reliable, that is isolated.In general, the process of replacement takes less than 20 minutes.If you decide to repair the compressor of a refrigerator with his hands, then get ready for difficulties.First rung relay possible, the matter is in it, and so the equipment does not start.Then replace the oil in the compressor.If this does not work, the equipment can be thrown, special sense to mess with him there.
Conclusion
So we figured out how to make the compressor on the refrigerator with their own hands.Generally, during the execution of the works may have a variety of difficulties.Starting with the fact that the filter does not fit hoses, and ending with bad connections or a lack of response from the compressor.But most problems can be solved.In general, a compressor - a very useful thing.With it, you can do painting and other useful things.More important is how the airbrush or spray you use, rather than a compressor.The main purpose of this equipment - to ensure constant pressure.If there was a need for high pressure, say 3.5 bar and above, to find a suitable compressor is not difficult.Rather, it is the Soviet model.This is due to the fact that modern engines refrigerators, though not strong, very productive.That's all on this topic you can now get down to business.
