Working principle of screw compressor

Working principle of screw compressor The screw compressor cylinder is equipped with a pair of interlocking helical male and female rotors. Both rotors have several concave teeth, and the two rotate in opposite directions. The gap between the rotors and the casing and the rotor is only 5 ~ 10 filaments. The main rotor (also called the male rotor or the convex rotor) is driven by the engine or motor (mostly driven by the motor), and the other rotor (also called The female rotor or female rotor) is driven by the oil film formed by the main rotor through oil injection, or by the synchronous gears at the main rotor end and the female rotor end. So there is no metal contact (in theory) in the drive. The length and diameter of the rotor determine the compressor displacement (flow rate) and discharge pressure. The longer the rotor, the higher the pressure; the larger the rotor diameter, the greater the flow.
