Definition and principle of air compressor
The air compressor is the main body in the air source device, which is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pneumatic generating device for compressed air. The core component of the air compressor is the compressor main engine, which is one of the volumetric compressors. The compression of the air is achieved by the volume change of the tooth grooves of the male and female rotors that are arranged in parallel with each other in the casing. Rotating the rotor pair in the housing with its precise fit causes the gas between the rotor slots to continuously produce a periodic volume change along the rotor axis, from the suction side to the discharge side, completing the suction, compression, and exhaust Work process. Therefore, the profile technology of the twin-screw rotor determines the grade of the screw air compressor product positioning.
