The roots vacuum pump is a mechanical vacuum pump with a pair of synchronous high-speed rotation sole-shaped rotors, this pump can not be pumped separately, the front stage needs to be equipped with an oil seal, water ring, etc., and can be directly discharged into the atmosphere. Its structure and working principle are similar to Roots blower, and its suction port is connected to the vacuum container or the main pump of the vacuum system when it works.
