Dry Screw Vacuum Pump Advantages

Dry screw vacuum pump mainly uses a pair of screw. Its characteristic is that the two screw are corrected by fine dynamic balance, supported by bearing and installed in the pump shell. There is a certain gap between screw and screw, so that when dry screw vacuum pump works, there is no friction between them, smooth operation, low noise and no need for working chamber. Lubricating oil, dry screw pump can remove gas containing a large amount of steam and a small amount of dust, the limit vacuum is higher. But the screw pump used in our country mainly depends on imports, and the price is very expensive.

Dry screw vacuum pump, which uses a pair of screw, in the pump shell as a synchronous high-speed reverse rotation of the suction and exhaust effect of the suction equipment. Its advantages make up for the shortcomings of oil-sealed vacuum pump, which we all call the upgraded version of oil-sealed vacuum pump. But the cost of dry screw vacuum pump is also its shortcomings. Next, it mainly introduces its advantages and disadvantages:rotary-vane-vacuum-pump-in-petrochemical-industry

Dry Screw Vacuum Pump Advantages：

1. The working chamber and the surface of the screw rotor are coated with anticorrosive coating, which can adapt to harsh working conditions.

2. Gas is not compressed in the pump, so it is suitable to extract condensable gas.

3. No fuel consumption, no drip and leakage

4. The structure is simple and easy to maintain. screw-vacuum-pump-in-metallurgical-industry

5. The pumped gas is directly discharged from the pump body, which does not pollute water, has no environmental protection pressure and makes gas recovery more convenient.rotary-vacuum-pump-application
