PR Roots Vacuum Pump

Roots Vacuum Pump (referred to as roots pump) is a rotary variable volume vacuum pump without internal compression. It uses two 8-shaped rotors to rotate in the pump shell to produce suction and exhaust. Its principle is similar to that of Roots blower. Because it works in the low pressure range, the free path of gas molecules is large, and the resistance of gas leakage through small gaps is large, so it can obtain a high compression ratio and can be used as a booster variable frequency vacuum pump; However, it can not discharge the gas directly into the atmosphere alone. It needs to be used in series with the front stage variable frequency screw vacuum pump, and the pumped gas is discharged into the atmosphere through the front stage vacuum pump.
