How do Rotary Screw Air Compressors Work？

Rotary screw air compressor working principle is :The spiral rotor groove is filled with gas as it passes through the suction port,when the rotor rotates, the rotor groove is closed by the wall of the casing, forming a compression chamber, when the rotor groove is closed, the lubricating oil is sprayed into the compression chamber to seal and cool. When the rotor rotates and compresses the oil-gas mixture, the volume of the compression chamber decreases and the oil-gas mixture is compressed towards the exhaust port. When the compression chamber reach to the exhaust port, the oil and gas mixture from the compressor discharge, complete a suction – compression – exhaust process.

How to Size Suitable Air Compressor？

To find out the suitable size air compressor, the first thing you should know is the major factors that determine the working competence of an air compressor, and then consider the type of air compressor based on your actual situation and requirements for compressed air,such as caculate the pressure and CFM requirements of your pnuematic tools.
