Working principle of screw compressor


Inhalation process: As the rotor rotates, the gear volume increases. Gases from the evaporation system

enter the gear volume through the suction holes. When the rotor rotates to a certain angle, the gear passes

through the suction hole and the suction process ends.


Compression process: As the rotor continues to rotate, due to the mutual meshing of the female and male

rotors and the compression of the rotor, the gas in the originally closed tooth slot is squeezed toward the

exhaust end, and the pressure also increases, and the compression process continues. With the compression



Exhaust process: When the rotor rotates to the position where the tooth slot is connected to the exhaust port,

the gas will be discharged from the exhaust port, completing the exhaust process.Since the above three processes

occur in each tooth slot in sequence, when the compressor is running at high speed, each tooth slot undergoes

repeated cycles of suction, compression and exhaust, ensuring the continuous

stability of the compressor gas.

Features of screw compressors

1. The screw compressor has a simple structure, few parts, and no wearing parts. The friction rotor and bearings

have high strength and wear resistance, and good lubrication conditions, so the operation cycle is long, maintenance

is simple and reliable, and operation automation can be realized.
2. The screw compressor has the characteristics of forced gas transmission, and the displacement is basically not

affected by the exhaust pressure.
3. Using slide valve adjustment, it can realize stepless adjustment of energy and high volumetric efficiency.
4. The screw compressor is not sensitive to liquid inlet and can be cooled by oil injection.
