(Summary description)Air compressors are one of the necessary power equipment for many enterprises, and screw air compressors are the mainstream products in the air compressor market today. For an air compressor, the main function is to produce gas, which makes the air compressed with pressure. The working principle of the screw air compressor is mainly divided into three processes: suction, compression, and exhaust.

Inhalation process. The screw-type intake side intake port must be designed so that the compression chamber can be fully inhaled. The screw air compressor does not have an intake and exhaust valve group. The intake air is only regulated by the opening and closing of a regulating valve. When the rotor rotates, the tooth groove space of the main and auxiliary rotors turns to the opening of the intake end wall. , and its space is the largest. At this time, the cogging space of the rotor is the same as the free air in the air inlet, because the air in the cogging is completely excluded when exhausting.

When the exhaust is completed, the tooth groove is in a vacuum state. When it is turned to the air inlet, the outside air is sucked in and flows into the tooth groove of the main and auxiliary rotors in the axial direction. When the air fills the entire tooth groove, the end face of the intake side of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed.

Compression process. In the process of gas delivery, the meshing surface gradually moves towards the exhaust end, that is, the gap between the meshing surface and the exhaust port gradually decreases, the gas in the tooth groove is gradually compressed, and the pressure increases, which is the compression process.

Exhaust process: When the meshing end face of the rotor turns to communicate with the exhaust of the casing, the compressed gas starts to be discharged, until the meshing surface of the tooth crest and the tooth groove moves to the exhaust end face, at this time the meshing surface of the two rotors and the casing are The tooth gap space of the exhaust port is zero, that is, the exhaust process is completed.
