Receiver for the compressor: pick up or do it yourself? – Setafi

How to pump your automotive or industrial pump so that it pumps twice or even three times faster? Or another one: how to get rid of rust in a car pump? These questions often appear not only on the Internet, but also in real everyday situations.

You bought a compressor, have been using it for a year or two. And then his cylinder stopped pumping air: the wall was pierced and all the air mass does not go out through the pipes, but simply into the atmosphere. No amount of tape will help.

In our article, we will take a closer look at the “panacea” for such a problem - an additional receiver for the compressor: how to choose it and whether it is possible to do it yourself. Let's start!

Compressor receiver - what is it

We will not go into details of the structure of the equipment, but we will simply and clearly tell you - this is a container (sealed) that holds air in the compressor, stabilizes the pressure in the air pumping system. The receiver is not a mandatory piece of equipment, but a "nice addition" to an existing system. But, practice shows that such an addition as a receiver in a compressor is necessary in professional production and in everyday life. And why - read on.

One of the main tasks of the receiver is to remove condensate from pressurized air. This reduces the effect of corrosion on the inner walls and tubes of the pump. The list of functions of the device does not end there.

Pressurized air collection

The performance of one pump may not be enough when you use several air tools at once. With the drive, you will have enough air with a margin.

Reduced time between pump cycles

In automatic mode, the compressor turns on when the parameter decreases and turns off when the recommended pressure is reached. Traditionally, this difference is always 2 Bar. And what are these 2 Bars? Blow through the part with a blow gun a couple of times.

With the use of a receiver, the on / off intervals of the pump increase, and we spend less electricity and the output of our device.

Elimination of pulsations in the pump tank

Piston compressors supply air not smoothly, but in pulses. Sometimes it causes inconvenience, but you won’t understand how to get rid of it. So, an additional air accumulator solves the problem once and for all - the pulsation effect disappears.

Now, we need to think about how to choose a compressor receiver for your situation? We will talk about this in the next subtopic of the article.

Where to look to get a good air receiver (receiver) for an industrial pump

You have already got acquainted with what a receiver is in general and what tasks it performs with pleasure for our compressor. It remains only to install it correctly or make it yourself.

In addition to the materials, we suggest that you familiarize yourself with all the basic characteristics that air collectors need:

• Volume. For household models and industry, the cylinder indicator is different. We start from 5 liters and up to several thousand (if you have a large production). Look also at the fact that the more powerful your pumping unit is, the more powerful the receiver is needed for it. How to calculate: the amount of addition should be from a third to a half of the performance of the compressor itself.
• Operating pressure. For a domestic receiver, this figure does not even reach 10 bar. Commercial and industrial pumps require an air receiver of 16 bar or more. This is already at your discretion and working needs.
• Bandwidth. The parameter means: how much air the receiver can drive through itself in 1 minute. The more compressed air you need to work, the stronger the throughput look for in the store.

That's all. Such a small list of parameters helps to determine whether you have purchased the right air collector. And, of course, to avoid critical errors and overpayments for unnecessary equipment.

Homemade receiver for a compressor: how to make it yourself

There is a list of works that require a large flow of air under pressure. And conventional compressors can not cope with this. One way to get out of the situation is to create a receiver for the compressor. You can do it yourself with a minimum set of knowledge.

Why is it better to make an additional receiver for the compressor? It's simple: a biting price. By the volume of the device, the cost of such an accessory starts from 10 thousand rubles or more. In addition, store receivers are focused on standard pumps - they may simply not be suitable for certain models.

How to choose a receiver for the compressor: you can connect it both independently and already to the main one. The last option is easier.

For the base, a gas cylinder or a simple fire extinguisher is used. The container is cleaned of the remnants of the products that were in it. After that, the inlet valve is removed (only with hand tools - there is a high probability of popping from gas residues).

The resulting container is filled with water and costs more than a day - it sours. Then, pipes under the hoses are welded into the cylinder. The tank is coated with anti-corrosion paint.

If you need to install additional nozzles (condensate drain or pressure gauge), then we make additional threaded connections.

The finished installation is placed on a rack or tripod made of steel. You need to use the model like this:

• A steam trap is required.
• Before loading, check the compressor itself for the ability to work with the calculation of the receiver. To do this, the pump is turned on at idle, and the difference is checked by the flow meter when turned on (you need to do the procedure for about 20 minutes). If the pressure does not jump and does not fall to the recommended value, then air can be pumped with the receiver.
• If the pressure drops, then the continuous operation of the regular compressor is reduced (from 75 to 50 percent).

Now you know how to set up and connect an additional receiver to the compressor. If you have any questions or suggestions feel free to ask them in the comments below. We are always happy to answer and supplement our materials!
