Operation Guidance of ZJ/ZJP Series Roots Vacuum Pump
This series of Roots pump has a pair of synchronous high-speed rotors inside the pump, which achieve suction and discharge when the rotors are rotating. Since it works in the low pressure intensity range, the free path of gas molecules is larger and the resistance of gas leakage through tiny gaps is large, thus a high compression ratio can be obtained.
It can be used as a booster pump in series with the pre-stage pump, which can be used as a slide valve pump or rotary vane pump, water ring pump, oil ring pump and other vacuum pumps, but cannot directly discharge the gas into the atmosphere.
Wide range of applications: such as chemical medicine, food, electrical equipment manufacturing, vacuum metallurgical industry, vacuum degassing, vacuum melting, vacuum treatment of steel, and insensitive to small amounts of dust, high ultimate vacuum. when it is used in series with the former pump, the ultimate vacuum is between 0.0004 ~ 0.0001 Torr.
