Gas Compressor: Scheme, Device and Types

The gas compressor serves to compress a certain amount of matter in the third aggregate state. The process is carried out by means of mechanical action. The gas compressor is used in various spheres of domestic and industrial economy. For example, devices are used to move gas through pipes to private homes and apartments, to reduce the air volume in turbines, 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 a larger scale, such islets are used to provide a breathing mixture of airplanes and submarines, as well as for storing natural gas.

Types of execution

The gas compressor is manufactured in different modifications. Each of the devices is freely available for sale in 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 stated earlier, gas devices are found in seven versions. Let's consider in detail each of them.

1. Centrifugal. It is, as a rule, used in the industrial sphere for the processing of gas and oil products, that is, at various chemical plants. This is where continuous work is needed, which it provides. Such units are used at various ski resorts to create artificial snow.
2. The arrangement of a gas compressor of the diagonal type is the same. As in the previous one. However, there is a difference: different sizes of the diffuser.
3. Compressors of the axial type are able to compress a large amount of gas. It consists of blades that perform continuous rotational movements. This scheme of the gas compressor is used for gas turbines.
4. Rotary machines are used in the industrial sector, where continuous work is needed. They are used in military affairs, as well as for various mechanisms when repairing roads. They are a popular substitute for car engines, because they are easy to set up and have the same power as piston engines.
5. Reciprocating gas compressor. Compression of fuel occurs due to the work of the pistons when the crankshaft rotates. They are also used in large industrial enterprises, since they are reliable and economical equipment.
6. The principle of the action of scroll compressors is to compress gas through two interconnected blades. Their main advantages are high reliability and quiet operation.
7. Diaphragm compressors are modernized piston equipment. That is, diaphragms are used instead of continuously working pistons.

Type of fuel

A huge advantage of gas compressors is the possibility of using different types of fuel. Manufacturers produce equipment that works not only with natural gas, but also with nitrogen, hydrogen, chlorine, argon, carbon dioxide and many others. Such equipment serves for transportation and supply of fuel.

Main types of equipment

There are three most common types of compressors:

1. Piston gas element. This device is the most common, although it has many shortcomings. First of all, this is a large consumption of oil and wear of working elements. But with proper use it will last a long time. Such a device is able to compress gas to pressure values from 50 to 4000 bar.
2. Screw compressor. Used in cases where it is necessary to achieve a pressure of 3 to 30 bar. It is used in automobile turbines. Due to its design, not only natural gas can be compressed, but also that produced from organic waste.
3. Booster compressors. They are used to increase pressure in working areas. If at standard operating points the pressure indicator reaches 15 bar, then with the use of equipment it increases to 4000 bar. It serves for pumping natural gas, as well as for refueling cylinders.

Preparatory work before assembly

Many people are wondering how to make a gas compressor with their own hands. This is a rather laborious work. Therefore, before it starts, you need to collect the necessary tools and tools. In addition, it is necessary to familiarize yourself with the principles of welding and locksmithing. We will collect the product from an ordinary refrigerator.

How to make a gas compressor?

The finished equipment will work absolutely silently. Therefore, it can be used even in the dark and do not worry about sleeping neighbors. But there is a significant disadvantage. The device will have low power. So, in order to make a gas compressor, you need to do the following:

1. 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.
2. Further, the necessary receiver is selected, which can serve as a ballon from a fire extinguisher. It should not have any mechanical damage, as well as traces of corrosion.
3. Then you need to buy a number of tools and tools: a hose, engine oil, filter, keys, check valve, sealant, relay.
4. The old compressor removes the pipes to empty it from the factory oil and fill it with a new one. This procedure can be performed using a hacksaw.
5. Take the fire extinguisher and install a crane instead of the locking mechanism. The joints are treated with a sealant. A valve is inserted into the hole to connect the hose.
6. The locking valve and reducer are connected to this opening, and then the hose itself.
7. A filter is installed before the hole through which air is drawn in, so that no dirt gets into the gasoline and oil.
8. After completing all the work necessary to fix the device using a self-made frame or other elements.

The result is an excellent device that can solve various everyday tasks.

Gas Compressor for Car Refueling

Such a device can also be manufactured independently. And there are several devices. One works on compressed gas, and the other - on liquefied gas. For the first type, fuel can be taken from a conventional domestic pipeline. But the pressure in it is small. Therefore, for refueling 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 the domestic pipeline passes through the filter and enters the inlet valve. Further, it compresses and moves to another contour, where compression takes place up to a high pressure. The number of circuits can be up to five, and in each of them, similar processes are performed.

After compression, the gas with a pressure of about 200 atm passes through the switch. Then it is cleaned in the filter. The gas enters the cylinder through a safety valve. The larger the capacity of the compressor unit, the faster the balloon will fill.

Conclusion

Gas compressor is a universal equipment, as it can be used not only in industry, but also for domestic needs. Its main task is to compress the gas and feed into different devices. This installation can (if there are certain skills) to collect houses and use to refuel the car. That's why many users choose these kinds of compressors. The cost of it is in the range of 5 to 70 thousand rubles, depending on the technical characteristics. If there are no such means, you can try to assemble the product yourself. The starting material is an old refrigerant compressor.

So, we found out what the equipment is for, and how it can be done by our own hands.
