The gas compressor is used to compress a certain amount of matter in the third state of aggregation. The process is carried out by means of mechanical action. The compressor gas is used in different spheres of household and industrial economy. For example, devices are used to move gas through pipes to private houses and apartments, to reduce the volume of air in turbines, to transfer heat in refrigeration equipment. Another application is in automotive service. With its help, the brake hoses are filled with compressed air. If we consider a gas compressor of larger volumes, then such units are used to provide breathing mixture for aircraft and submarines, as well as to store natural gas.
Performance types
The gas compressor is manufactured in different modifications.
Each of the devices is freely available insale in any construction market. So, they are produced in the following types:
- centrifugal;
- diagonal;
- axial;
- piston;
- screw;
- spiral;
- diaphragm.
Features of different types of products
As mentioned earlier, gas devices are found in seven versions. Let's consider each of them in detail.
- Centrifugal. It is usually used in the industrial sector for the processing of gas and oil products, that is, in various chemical plants. This is where continuous work is needed, which he provides. Such units are used at various ski resorts to create artificial snow.
- Diagonal type gas compressor device is the same. like the previous one. However, there is a difference: different diffuser sizes.
- Axial type compressors are capable of compressing large amounts of gas. It consists of blades that perform continuous rotational movements. This gas compressor layout is used for gas turbines.
- Rotary are used in the industrial sector, where continuous operation is needed. They are used in military affairs, as well as for various mechanisms in the repair of roads. They are a popular replacement for car engines as they are easy to tune and have the same horsepower as pistons.
- Gas piston compressor. Compression of fuel occurs due to the work of the pistons during the rotation of the crankshaft. They are also used in large industrial plants, as they arereliable and economical equipment.
- Scroll compressors work by compressing gas with two interlocking blades. Their main advantages are high reliability and quiet operation.
- Diaphragm compressors are upgraded reciprocating equipment. That is, diaphragms are used instead of continuous pistons.
Fuel type
A huge advantage of gas compressors is the ability to use different types of fuel.
Manufacturers manufacture equipment that works not only with natural gas, but also with nitrogen, hydrogen, chlorine, argon, carbon dioxide and many others. Such equipment is used to transport and supply fuel.
Main types of equipment
There are three most common types of compressors:
- Piston gas element. This device is the most common, although it has many disadvantages. First of all, this is a high oil consumption and wear of working elements. But with proper use, it will last a long time. Such a device is capable of compressing gas to pressures from 50 to 4000 bar.
- Screw compressor. It is used in cases where it is necessary to achieve a pressure of 3 to 30 bar. Used in automotive turbines. Due to its design, it can compress not only natural gas, but also that obtained from organic waste.
- Booster compressors. They are used forincrease in pressure in the working areas. If at standard operating moments the pressure indicator reaches 15 bar, then with the use of equipment it increases to 4000 bar. It is used for pumping natural gas, as well as for filling cylinders.
Preparatory work before assembly
Many people are wondering how to make a gas compressor with their own hands. This is quite labor intensive work.
Therefore, before starting it, you should collect the necessary fixtures and tools. In addition, it is necessary to familiarize yourself with the principles of welding and metalwork. We will assemble the product from a conventional refrigerator.
How to make a gas compressor?
The finished equipment will work completely silently. Therefore, it can be used even at night and not worry about the sleep of the neighbors.
But there is also a significant disadvantage. The device will have low power. So, in order to make a gas compressor, you must do the following:
- For these purposes, any compressor from an old refrigerator will do. You can remove it yourself. To do this, cut the wires and remove the relay.
- Next, the necessary receiver is selected, which can be a cylinder from a fire extinguisher. It should not have mechanical damage, as well as traces of corrosion.
- Then you need to buy a number of fixtures and tools: hose, engine oil, filter, wrenches, reversevalve, sealant, relay.
- Tubes are removed from the old compressor to drain it from the factory oil and fill in the new one. This procedure can be performed with a hacksaw.
- Take a fire extinguisher and install a tap instead of a locking mechanism. The joints are treated with sealant. A valve is inserted into the hole, which serves to connect the hose.
- Attach the shut-off valve and reducer to this hole, and then the hose itself.
- A filter is installed in front of the hole through which air is taken in, so that dirt and dirt do not get into gasoline and oil.
- After completion of all work, it is necessary to fix the device with a homemade frame or other elements.
The result is an excellent device that can solve various everyday tasks.
Gas compressor for car refueling
This fixture can also be made by yourself.
And there are several devices. One runs on compressed gas, and the other on liquefied gas. For the first type, fuel can be taken from an ordinary household pipeline. But the pressure is low. Therefore, to refuel a car, a compressor with several circuits is needed, capable of increasing the pressure to 200 atm.
The principle of operation is as follows. Natural gas from the domestic pipeline passes through the filter and enters the inlet valve. Then it is compressed and moved to another circuit, where it is compressed to high pressure. Quantitycircuits can reach up to five, and in each of them similar processes are performed.
After being compressed, the gas with a pressure of about 200 atm passes through the switch.
Then it is cleaned in the filter. Gas enters the cylinder through a safety valve. The greater the capacity of the compressor unit, the faster the cylinder will fill up.
Conclusion
The gas compressor is a versatile equipment, as it can be used not only in industry, but also for domestic needs. Its main task is to compress the gas and supply it to various devices. Such an installation can (if you have certain skills) be assembled at home and used to refuel a car. That is why many users choose these types of compressors.
Its cost is in the range from 5 to 70 thousand rubles, depending on the technical characteristics. If there are no such funds, you can try to assemble the product yourself. The starting material is an old refrigeration compressor.
So, we found out what this equipment is for and how you can make it yourself.
