The screw air compressor is an oil-injected single-stage twin-screw compressor. It adopts high-efficiency pulley (or shaft) transmission to drive the main engine to rotate for air compression. It cools and lubricates the compression chamber of the main engine through oil injection, and the air discharged from the compression chamber The gas mixed with oil undergoes coarse and fine separation to separate the oil in the compressed air, and finally obtain clean compressed air. It has excellent reliability performance. The unit's biggest advantages are light weight, low vibration, low noise, easy operation, few wearing parts and high operating efficiency.

The core component of the screw air compressor is the compressor main unit, which is a type of positive displacement compressor. The compression of air is achieved by the volume change of the tooth grooves of the male and female rotors installed in the casing and meshing in parallel with each other. The rotation of the rotor pair in the casing that is precisely matched with it causes the gas between the rotor tooth slots to continuously produce periodic volume changes and push from the suction side to the discharge side along the rotor axis, completing the three processes of suction, compression and exhaust. a work process. Therefore, the profile technology of the twin-screw rotor determines the grade of screw air compressor product positioning.
