The Function Of Vacuum Pump

Vacuum pump is a large quantity and wide range of products, the output is very large, the output value is not high, but it is a direct impact on the performance of vacuum equipment set of essential basic products. The market of vacuum pump changes dynamically according to the needs of users. The main driving force for market growth is the rapid development of the semiconductor industry and the increasing application of dry and molecular pumps.

Through the analysis of the global vacuum pump market, we can see that various types of vacuum pump market and application fields are constantly changing and developing. China’s vacuum pump manufacturing industry has a long history and a strong foundation, the domestic vacuum pump has been applied in various fields and verified, some pumps are exported abroad, foreign users recognized and praised, it should be said that China’s vacuum pump manufacturing industry in the domestic and foreign market is still a huge space for development. What are the functions of vacuum pumps?

The function of vacuum pump:

A device for obtaining and maintaining vacuum by means of mechanical, physical, chemical, physical and chemical methods. Vacuum pumps and other equipment (such as vacuum containers, vacuum valves, vacuum measuring instruments, connecting pipes, etc.) constitute a vacuum system, widely used in electronics, metallurgy, chemical industry, food, machinery, medicine, aerospace and other departments.

The increasing market of dry mechanical vacuum pumps abroad is mainly driven by the rapid development of semiconductor industry, chemical industry and film industry. In Japan, the semiconductor industry has all replaced oil seal mechanical pumps with dry vacuum pumps. More than 45% of the European and American semiconductor industries have replaced oil seal mechanical pumps with dry vacuum pumps, greatly improving the performance and quality of products.

In order to meet the requirements of different application fields and different working conditions, foreign countries have multi-stage Roots vacuum pump, multi-stage claw vacuum pump, screw vacuum pump, scroll vacuum pump, reciprocating piston vacuum pump and turbine oil-free vacuum pump. The limit pressure ranges from 10Pa to 10-2Pa, and the pumping speed ranges from 20m3/h to 500m3/h. According to statistics, the application of domestic dry pumps is less than 1%, and all the dry pumps used in domestic semiconductor industry are imported from abroad. The price is very expensive. Therefore, China should vigorously study and develop dry pumps, so that dry pumps become a new economic growth point of China’s vacuum industry.
