Operating Principle of Roots Pump
Roots pump with overflow valve (hereinafter referred to as roots pump) realizes the air extraction function through a pair of “8” shaped rotors that interact with each other and rotate synchronously and reversely. When the rotor and the pump body form a suction chamber, the two rotors are always sealed with each other. So as to ensure that the gas at the exhaust port does not flow back to the air inlet, so as to realize the function of air extraction.
The reverse synchronous rotation of the rotor is realized by a pair of gears installed on the rotor shaft. Because there is no friction in the pump chamber, the roots pump can run at a high speed of 1500 ~ 3000 revolutions per second without lubrication in the pump chamber. In addition, to keep the roots pump running smoothly at high speed, it is necessary to carry out a good dynamic balance on the rotor.
There is no direct contact between the rotors rotating at high speed and between the rotor and the pump body. And a certain clearance is maintained between the moving parts.
Application
The roots pump with an overflow valve is equipped with a built-in overflow valve between the inlet and outlet. Its function is: when the pressure difference at the inlet and outlet reaches a certain value. The overflow valve will automatically open. And part of the gas at the outlet will flow back to the inlet through the opened overflow valve. Which greatly reduces the operating load of roots pump and front-stage vacuum pump. (hereinafter referred to as front stage pump) under high-pressure difference.
At the same time, because the opened overflow valve has a strong discharge function. It can ensure that the Roots pump with the overflow valve. And the front stage pump can be started at the same time without overloading the roots pump and the front stage pump. And can improve the pumping speed of roots pump unit under high inlet pressure.
