The screw vacuum pump has a simple structure, but its processing technology requires higher requirements. It must ensure that the height between rotors is parallel, and that between rotors and between rotors and the inner wall of the pump body, there is a very small gap and no friction caused by contact, so as to ensure the realization of gas transmission and reduce gas backflow without the need for oil lubrication and sealing.The screw vacuum pump has a simple structure, but its processing technology requires higher requirements.

Summary
The dry screw vacuum pump is a rotor that uses a pair of parallel screws to make synchronous, high-speed and reverse rotation in the pump housing. The rotor and the inner wall of the pump body form a number of sealing spaces. During the rotation, the continuous transmission of gas is formed to achieve the purpose of suction and exhaust.
