Roots Vacuum Pump

Roots vacuum pump

Roots vacuum pump (abbreviation: Roots pump) refers to a kind of variable capacity vacuum pump with two leaf-shaped rotors that rotate synchronously in opposite directions in the pump. There is a small gap between the rotors and the inner wall of the rotor and the pump housing without contact with each other.

Roots vacuum pumps have been tested for long-term operation in petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balancing, aerospace space simulation and other devices, so they should be vigorously promoted and applied in China.At the same time, it is also widely used in petroleum, chemical, metallurgical, textile and other industries.Vacuum pump accessories are used as vacuum pump silencers for noise control of vacuum pumps.

Roots pump is a kind of vacuum pump without internal compression. The compression ratio is usually very low, so high and medium vacuum pumps require a pre-stage pump.

A vacuum pump that relies on the synchronous and reverse rotation of a pair of leaf-shaped rotors in the pump chamber to move the gas and realize the pumping.

Roots vacuum pump refers to a mechanical vacuum pump with a pair of shoe-shaped rotors that rotate synchronously and at high speed. This pump cannot be pumped separately. The front stage needs to be equipped with oil seals, water rings, etc. To discharge directly into the atmosphere.
