Working principle of inverter compressor

     The principle of inverter compressor inverter controller is to convert the alternating current in the power grid into a square wave pulse output. By adjusting the frequency of the square wave pulse (that is, adjusting the duty cycle), the speed of thﰸ2䀀

Maintenance of screw air compressor

1. Maintenance of intake air filter element. The air filter is a component that filters out air dust and dirt. The filtered clean air enters the compression chamber of the screw rotor for compression. Because the internal clearance of the screw machine only allows particles within 15u to filter out.
