Industry Dry Vacuum Pump Manufacturer
There are many manufacturers of Industry dry vacuum pumps on the market. Before choosing manufacturers, we should know what the role of such pumps is. Dry vacuum pump is a mechanical vacuum pump that can start pumping at atmospheric pressure and directly discharge the pumped gas into the atmosphere. There is no oil or other working medium in the pump chamber, and the limit pressure of the pump is the same or close to that of the oil-sealed vacuum pump. There are mainly dry screw vacuum pump, oil-free reciprocating vacuum pump, claw vacuum pump and oil-free scroll vacuum pump, which are widely used.
Dry vacuum pump applications:
1. Distillation, drying, defoaming and packaging in chemical industry, pharmaceutical industry and food industry should prevent pollution caused by organic solvents and be suitable for dry vacuum pumps.
2. In addition to semiconductor technology, some processes that produce particulate matter do not want particulate matter to be mixed into the pump oil, but want particulate matter to be discharged from the pump. A certain type of dry vacuum pump can meet the requirements.
3. Dry vacuum pump can be used as the front pump of general oil-free clean vacuum system to prevent oil pollution.
4. Semiconductor etching process. Corrosive gases and abrasive particles are often used or generated in these processes.
5. Polycrystalline silicon in low pressure chemical vapor deposition.
With the development of science and technology, the technology of dry vacuum pump manufacturer has been improved constantly, which is less affected by reactants and has good stability. Choose a good manufacturer to buy, the quality is more guaranteed.
