 Basic introduction

Roots vacuum pump has been tested by long-term operation in petroleum, chemical industry, plastics, pesticides, 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, metallurgical, textile and other industries. Vacuum pump accessories for noise control of vacuum pump, vacuum pump.
Performance characteristics:
Roots vacuum pump is characterized by fast start-up, low power consumption, low operation and maintenance costs, high pumping speed and efficiency, insensitive to a small amount of water vapor and dust contained in the pumped gas, large pumping rate in the pressure range of 100-1 Pa, and rapid elimination of sudden gas release. This pressure range is just between the oil-sealed mechanical vacuum pump and the diffusion pump. Therefore, it is often connected in series between the diffusion pump and the oil-sealed mechanical vacuum pump to increase the pumping capacity in the middle pressure range. At this time it is also called mechanical booster pump.
Roots vacuum pump is widely used in vacuum metallurgy, such as smelting, degassing, rolling, vacuum distillation, vacuum concentration and vacuum drying in chemical, food and pharmaceutical industries. Vacuum pump accessories for noise control of vacuum pump, vacuum pump.
Matters needing attention:
The working principle and performance characteristics of Roots pump are essentially the same as that of cam pump, but the rotor is Roots type. It can transport liquids with viscosities of tens of thousands of centimeters. Roots pump mainly has two rotors with opposite rotating directions in the pump body, which are driven by a pair of synchronous gears. For the rotors of Roots pump, they mesh with each other in the pump body, but have clearance. The size of the gap depends mainly on the liquid viscosity. The clearance must be adjusted and increased beyond a certain range of viscosity.
