Roots vacuum pump equipment refers to a variable-volume vacuum pump with two lobe-shaped rotors that rotate synchronously in opposite directions in the pump.

　　Roots vacuum pump equipment has been tested for long-term operation in petroleum, chemical, plastic, pesticide, steam turbine rotor dynamic balance, aerospace space simulation and other devices, so it should be vigorously promoted and applied in China. It is also widely used in petroleum, chemical, metallurgy, textile and other industries. Roots vacuum pump equipment accessories are used as vacuum pump silencers for noise control of vacuum pumps.

　　Roots pump is a vacuum pump without internal compression. Usually the compression ratio is very low, so high and medium vacuum pumps need backing pumps. It is a vacuum pump that realizes pumping by moving the gas by the pushing action of a pair of leaf-shaped rotors in the pump cavity synchronously and counter-rotating.

　　Roots vacuum pump equipment refers to a mechanical vacuum pump with a pair of sole-shaped rotors that rotate synchronously at high speed. This pump cannot be pumped alone, and the front stage needs to be equipped with oil seals, water rings, etc., which can directly exhaust the atmosphere. Its structure and working principle are similar to those of the Roots vacuum pump equipment Roots blower, and its suction port is connected to the vacuumed container or the main pump of the vacuum system during operation. There is no contact between the rotor and the rotor and between the rotor and the pump casing of the Roots vacuum pump equipment.
