The gas compressor is used to compress a certain amount of substance in the third state of aggregation. The process is carried out through mechanical action. The gas compressor is used in various fields of domestic 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, and to transfer heat in refrigeration equipment. Another application is 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 a breathing mixture for airplanes and submarines, as well as for storing natural gas.
Types of Execution
The gas compressor is manufactured in various versions.
Each of the devices is freely available for sale on any construction market. So, they are made of 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 us consider each of them in detail.
- Centrifugal. As a rule, it is used in the industrial sphere for the processing of gas and oil products, that is, in various chemical plants. This is where the continuous work that he provides is needed. Such units are used in various ski resorts to create artificial snow.
- The device of the gas compressor of the diagonal type is the same. like the previous one. However, there is a difference: different sizes of the diffuser.
- Axial type compressors are capable of compressing a large amount of gas. It consists of blades that perform continuous rotational movements. Such a gas compressor circuit 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 substitute for automotive engines, as they are easy to adjust and have the same power as piston engines.
- Gas piston compressor. The compression of the fuel occurs due to the operation of the pistons during rotation of the crankshaft. They are also used in large industrial enterprises, as they are reliable and economical equipment.
- The principle of operation of scroll compressors consists in gas compression due to two interconnected blades. Their main advantages are high reliability and quiet operation.
- Diaphragm compressors are modernized piston equipment. That is, instead of continuously operating pistons, diaphragms are used.
Type of fuel
A huge advantage of gas compressors is the ability to use various types of fuel.
Manufacturers make 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.
The 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, it is a large oil consumption and wear of working elements. But with proper operation, it will last a long time. Such an apparatus is capable of compressing gas up to pressure indicators 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. It is applied in automobile turbines. Due to its design, it can compress not only natural gas, but also one that is obtained from organic waste.
- Booster compressors. They are used to increase pressure on work sites. If at standard operating moments the pressure reaches 15 bar, then with the use of equipment it increases to 4000 bar. It serves 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 a rather laborious job.
Therefore, before it begins, it is necessary to collect the necessary devices and tools. In addition, it is necessary to familiarize yourself with the principles of welding and locksmithing. We will assemble the product from an ordinary refrigerator.
How to make a gas compressor?
Finished equipment will work completely silently. Therefore, it can be used even in the dark and not worry about the sleep of neighbors.
But there is a significant minus. The device will have low power. So, in order to make a gas compressor, you must perform the following steps:
- For these purposes, any compressor from an old refrigerator is suitable. You can remove it yourself. To do this, cut the wires and remove the relay.
- Next, the necessary receiver is selected, which can serve as 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 devices and tools: hose, engine oil, filter, keys, check valve, sealant, relay.
- At the old compressor tubes are removed to empty it from the factory oil and fill in a new one. This procedure can be performed using a hacksaw.
- Take a fire extinguisher and install a crane in place of the locking mechanism. The joints are sealed. A valve is inserted into the hole, which serves to connect the hose.
- The shut-off valve and gearbox are connected to this hole, and then the hose itself.
- A filter is installed in front of the hole through which air is drawn in to prevent dirt from entering the gas and oil.
- After completing all the work, it is necessary to fix the device using a makeshift frame or other elements.
The result is an excellent device that can solve various everyday problems.
Gas compressor for refueling a car
Such a device can also be made independently.
Moreover, 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 small. Therefore, to refuel a car, a compressor with several circuits is required, capable of increasing the pressure to 200 atm.
The principle of operation is as follows. Natural gas from a domestic pipeline passes through a filter and enters the inlet valve. Then it is compressed and moved to another circuit, where it is compressed to high pressure. The number of circuits can reach up to five, and in each of them similar processes are performed.
After compression, 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 performance of the
compressor unit, the faster the balloon will fill.
Conclusion
The gas compressor is a universal equipment, since it can be used not only in industry, but also for domestic needs. Its main task is gas compression and supply to different devices. Such an installation can (if you have certain skills) be assembled at home and used to refuel the 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 intended for and how to do it yourself.
