The dry screw vacuum pump is a pumping device that uses a pair of screws to make a synchronous high-speed reverse rotation in the pump casing, and the two screws are corrected by fine dynamic balance, supported by bearings, and installed in the pump. In the shell, there is a certain gap between the screw and the screw. Therefore, when the pump is working, there is no friction between each other, the operation is stable, the noise is low, and the working chamber does not need lubricating oil. Therefore, the dry screw pump can remove a large amount of water vapor. And a small amount of dust gas. The pumped gas has no compression in the working chamber, the ultimate vacuum is higher, the power consumption is lower, and the utility model has the advantages of energy saving and maintenance-free. It is a new generation of oil-sealed vacuum pumps.
especially in:
1) purification and special drying treatment of pharmaceutical industry products 2) reduction of dissolved substances, such as drying, filtration, crystallization and distillation treatment process 3) vacuum extraction of food industry 4) vacuum infusion in beverage industry 5) suction extrusion Machine 6) Recycling of process gas 7) Vacuum separation of mixture with boiling point 8) Emptying of gas in bottle before high-purity gas injection 9) Vacuuming in laboratory center and vacuum pumping in aircraft factory laboratory 10) All with oil The vacuum process in which the reaction takes place If the disadvantage of using the rotary vane pump is time, consider adding a Roots vacuum pump to the rotary vane pump, which can greatly shorten the pumping time. The Roots vacuum pump was developed for this purpose and also reduces power consumption.
