Dry-type screw vacuum pump, is the use of a pair of screws in the pump housing for synchronous high-speed reverse rotation of the suction and exhaust air suction device, the two screws fine balance correction by the bearing support, installed in the pump Shell, there is a certain gap between the screw and the screw, so the pump work, no friction between each other, smooth operation, low noise, the working chamber without lubricating oil, therefore, the dry screw pump can extract containing a large amount of water vapor And a small amount of dust gas occasions. Exhausted gas in the work chamber with or without compression, higher ultimate vacuum, lower power consumption, with energy saving, maintenance-free advantages. It is a replacement oil seal vacuum pump products. In particular: 1) Purification and special drying of pharmaceutical products 2) Reduction of dissolved substances, such as drying, filtration, crystallization and distillation processes 3) Vacuum extraction in the food industry 4) Vacuum infusion in the beverage industry 5) Exhaust Extruder 6) Recirculation of Process Gas 7) Vacuum Separation of Boiling Point Mixture 8) Gas Evacuation in Bottle Prior to High Purity Gas Injection 9) Laboratory Center Evacuation and Aircraft Factory Vacuum Evacuation 10 ) All the vacuum reaction process with the oil If the disadvantage of rotary vane pump is the time, consider adding a Roots vacuum pump to the vane pump can greatly shorten the suction time. Roots vacuum pump is developed for this purpose, you can also reduce power consumption.
