RMD dry variable pitch screw vacuum pump

Dry screw vacuum pump is a high-tech product with very high technical content. It is mainly used in high-purity vacuum process. The vacuum is extremely high and can be adapted to harsh working conditions. It has the ability to extract condensable and particulate gas, and is especially suitable for electronics. Chemical and biomedical fields. The dry screw vacuum pump is a pumping device that uses a pair of screws to perform synchronous high-speed and reverse rotation in the pump casing to produce suction and exhaust. The two screws are adjusted by fine dynamic balance and are supported by bearings. In the shell, there is a certain gap between the screw and the screw...
