What Are the Parts of Compressor?

Air compressors are similar in construction to water pumps. Most of them belong to the reciprocating piston, and the compressor is directly driven by the motor to make the crankshaft rotate, and the connecting rod is driven to make the piston reciprocate, causing the cylinder volume to change.

Because the pressure changes in the cylinder, air enters the machine through the air filter. In the process of pressure reduction, due to the reduction of air volume, air enters the air storage tank through the air exhaust pipe and the one-way valve. When the exhaust pressure reaches the rated pressure, the compressor will automatically stop. The air compressor is to provide power for the air source. It is the core equipment of the pneumatic system and the main body of the intake system. Therefore, it is very important to choose the appropriate air compressor at a professional compressor parts store.

 

What is an air compressor used for？

What Are The Parts of Compressor？ The air compressor is a device used to compress air. The following are the types of compressors:

1. According to its working principle, it can be divided into positive displacement compressor, dynamic compressor, and thermal compressor.

2. According to the lubrication method, it can be divided into oil-free air compressors and oil-lubricated air compressors.

The main function of an air compressor:

1. Controls the braking system of a car.

2. Cool down the brakes to avoid brake failure.

3. The heart of the A/C compressor, helps the refrigerator change from gas to liquid.

4. Provides aerodynamic power to the machine.

 

Main Parts of Air Compressor

The following air compressor parts often need to be maintained and replaced in daily use:

Compressor: Suck and compress the air.

Air cooler: As the parts of an air compressor, during the air compression process, the temperature will rise. In order to avoid damage to the equipment, the air needs to be cooled and then transported to the place where the equipment is needed.

Air receiver tank: Used to store compressed air.

Filter: Filter the impurities in the air and prolong the service life of the compressor.

Dryer: As the parts of an air compressor, the purpose of the air dryer is to suppress the dew point of the compressed air by removing the moisture in the compressed air, preventing it from condensing into harmful liquid and causing corrosion to the equipment.

Condensate trap: Used to discharge the water and oil generated during the use of the compressor.

Distribution System: As the parts of an air compressor, air transmission system, which continuously delivers air to the place where the equipment needs to operate while ensuring the quality, pressure, and flow of air.

 

Types of Compressor

Fixed displacement compressor: Fixed displacement compressors increase displacement proportionally to engine speed. It cannot automatically change the power output according to the cooling demand, which has a great impact on engine fuel consumption. Generally, it is controlled by collecting the temperature signal at the outlet of the evaporator. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released, and the compressor stops working.

Variable displacement air compressor: Variable displacement compressors automatically adjust power output based on temperature. The air-conditioning control system does not collect the temperature signal of the air outlet of the evaporator but controls the compression ratio of the compressor according to the pressure change signal in the air-conditioning pipeline to automatically adjust the temperature of the air outlet.

Crankshaft connecting rod compressor: The working process of this compressor can be divided into four parts, namely compression, exhaust, expansion, and suction. When the crankshaft rotates, the connecting rod drives the piston to reciprocate, and the working volume composed of the inner wall of the cylinder, the cylinder head, and the top surface of the piston changes periodically. Finally, playing the role of compressing and transporting refrigerant in the refrigeration system.
