Screw screw rotation speed of the selection of a linear relationship between the flow and speed of the screw vacuum pump maintenance, with respect to the low speed screw and high speed screw, been able to increase the flow and head, but significantly increased power, high-speed acceleration of the rotor and wear three-screw pumps between the stator, will make screw premature failure, and high speed screw pump rotor length is very short, easy to wear screw vacuum pumps, thus shortening the life of the screw pump. By variable speed reduction mechanism or institution to reduce speed, its rotational speed is maintained at $ 300 per rotation within reasonable range of the following screw vacuum pump repair, compared with the high-speed operation of the screw pump, life can be extended several times. Overview screw screw vacuum pumps is the use of a pair of screw for high-speed synchronous reverse rotation of the pump housing and the suction and discharge action generates extraction equipment, it is oil-sealed vacuum pump replacement products, can contain a large number of extraction dust, water vapor and a small amount of gas applications, the major pharmaceutical and chemical enterprises are widely used.
