Development History Of Vacuum Pump

With the development of vacuum applications, many types of vacuum pumps have been developed, and their pumping speeds range from a few tenths of a liter per second to hundreds of thousands and millions of liters per second. As vacuum technology has wider and wider requirements for its application pressure range in the field of production and scientific research, most of them need to be composed of several vacuum pumps to pump together to meet the requirements of the production and scientific research process. The range of working pressure involved in the application department is very wide, so any type of vacuum pump cannot be completely suitable for all working pressure ranges, and only different types of vacuum pumps can be used according to different working pressure ranges and different working requirements. . For the convenience of use and the needs of various vacuum processes, various vacuum pumps are sometimes combined according to their performance requirements and applied in unit type.

Commonly used vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps, etc. These pumps are the indispensable main pumps in the application of vacuum processes in various industries of my country's national economy. kind. In recent years, with the sustained and rapid development of my country's economy, the vacuum pump related downstream application industry has maintained a rapid growth momentum. At the same time, driven by factors such as the continuous expansion of the vacuum pump application field, my country's vacuum pump industry has achieved sustained, stable and rapid development.
