Horizontal screw dry vacuum pump

Dry screw vacuum pump is the use of a pair of screw, in the pump shell for synchronous high-speed reverse rotation of the suction and exhaust effect of the extraction equipment. Between screw and screw has a certain gap, so the pump is working, no friction between each other, smooth running, low noise, working cavity without lubricating oil, therefore, dry screw pump can pump in addition to containing a large amount of water vapor and a small amount of dust gas occasions, limiting vacuum is higher, lower power consumption, energy saving, maintenance free, etc.

Characteristics of horizontal screw dry vacuum pump:

1. There is no medium in the working chamber, so a clean vacuum can be obtained;

2. Anti-corrosion coating is provided on the surface of working cavity and screw rotor, which can adapt to harsh working conditions;

3. The gas is not compressed in the pump, so it is suitable to extract condensable gas;

4. A single pump can be pumped from the atmosphere to 1Pa, and the vacuum system can be greatly simplified;

5. No oil consumption, no dripping;

6. No friction between rotating parts, high-speed operation, small machine size;

7. Simple structure and easy maintenance;

8. The pumped gas is directly discharged from the pump body, which does not pollute water and has no environmental protection pressure, making gas recovery more convenient.

Horizontal screw dry vacuum pump advantages

1. High vacuum, strong air extraction ability, higher pumping speed and vacuum degree than other vacuum pumps;

2. Low work energy consumption, which is 20%-60% lower than other pumps;

3. Strong adaptability in working conditions, liquid droplets and dust containing a small amount can be removed, and corrosive gas can be removed after material matching;

4. Good environmental protection, no industrial waste water, greatly reduce the cost of environmental protection;

5. High safety, no contact wear in internal design, no pollution of materials, no internal spark, excellent explosion-proof performance;

6. Compact structure, small site occupation and low installation cost;

7. Easy maintenance, advanced modular design, easy maintenance;

8. Solvent can be recovered. The exhaust port and condenser can recover the important chemical solvent.
