Rotary screw air compressor working principle
How does an air compressor work? Screw air compressors are volumetric compressors, the piston of which is in the form of a screw; this is the most important type of compressor used today. The main components of the screw compression element are a convex rotor and a concave rotor, and the two rotors move close to each other, so that the volume between them and inside the cavity gradually decreases. The screw pressure ratio depends on the length and shape of the screw and the shape of the exhaust port. The screw element is not equipped with any valve and there is no mechanical force that creates an imbalance.
