What is a Compressor?

A compressor is a mechanical device in which the pressure and density of a gas or vapor can be increased. These machines are used all over the world for different applications.

A compressor works in the same way as a pump. The main difference is that a pump is used for incompressible fluids while a compressor is used for compressible fluids. 

Component of the Compressors

1) Rotor

All of these components rotate in a centrifugal compressor and are called rotors.

2) Shaft

The shaft is the main support of the rotating part. It is made of durable metal. Connects to other components such as impeller, level drum, thrust ring, bearings, seals.

3) Impeller

The impeller is an integral part of the centrifugal compressors. With the help of the gas molecules, they become a moving force.

4) Balance and drum

For the compressor, this part is called the balance plate. In the case of turbines, this is called a balancing drum. In the case of the pump, this part is called the balanced piston. The main function of the balancing drum is to prevent axial movement of the compressor rotor.

For compressors, the scale or drum scale is center or right. In the case of a high-pressure compressor (over 40 kg), the balance plate is in the center. For low pressures (40 kg), the scale or drum scale is on the left. When the scale or drum plate is on the right side, the compressor suction tube is connected to the right side of the scale or drum plate. The result is that the pressure in this space is equal to that of the compressor. As a result, the compressor rotor cannot be accidentally moved to the left. This is the principle of operation of the compressor graduated plate or graduated drum.

5) Seal

The high-pressure gas molecules at the opening of the hermetic compressor prevent the molecules from moving outward or under pressure. The compressor uses three-point seals.

6) Diaphragm and Diffuser

The compressor diaphragm and the diffuser are the static part of the compressor. Like other compressors in the body, the diffuser is one of the hollow spaces. The gas molecules in the impeller become a moving force to create a lot of pressure.

7) Crankshaft

The crankshaft is an integral part of the precision compressor that maintains or connects the drive system and connecting rod.

Types of Compressors

1) Positive Displacement Compressors

Positive displacement compressors include a variety of air compressors that generate energy through air replacement. The principle of operation of this type is different, but the principle is the same. The cavity inside the device stores air from the outside and then gently compresses the cavity to increase the air pressure and potential energy.

2) Rotary screw compressor

Like typical positive displacement compressors, screw comp are the simplest type of air compressors to maintain because they are equipped with an internal cooling system and do not require much maintenance. These are usually large industrial machines that can lubricate.

The screw air compressors generate power through two internal rotors that rotate in opposite directions. Air gets stuck between two opposing rotors and creates pressure in the chamber. Thanks to the internal cooling system, these air compressors are designed for continuous use, and their power is between 5 and 350 hp.

3) Reciprocating Compressor

It usually uses in smaller workplaces such as garages and home construction projects. Unlike screw compressors, reciprocating compressors are not designed for continuous use. These have more moving parts than screw compressors, and these parts are lubricated with oil to move them more smoothly.

These types of air compressors work through the pistons in the cylinders, which prevent the creation and prevention of air pressure. Reciprocating compressors can have single or multistage displacements, which can affect their pressure range.

4) Dynamic Compressors

Dynamic air compressors draw in air through rapidly rotating blades and then limit the pressure created by the air to produce power. The moving energy is then statically stored in the comp.

5) Axial compressor

Axial air compressors are not commonly used in construction projects but are used at engine speeds on ships or aircraft. They are very efficient, but they are more expensive than other types of air comp and can reach thousands of horsepower, which is why they are mainly used in aerospace research.

6) Centrifugal Compressors

The centrifugal compressor slows down and cools the incoming air through a diffuser to collect potential energy. Thanks to the multiphase compression process, centrifugal compressors can generate a lot of power in a small machine.
