Vacuum pump development history
With the development of vacuum applications, many kinds of vacuum pumps have been developed, with pumping speeds ranging from a few liters per second to hundreds of thousands or millions of liters per second.
As the requirements of vacuum technology in the field of production and scientific research for its application pressure range become wider and wider, most of them need several vacuum pumps to form a vacuum pumping system to pump together to meet the requirements of production and scientific research process.
Due to the wide range of working pressure involved in the vacuum application sector, so any type of vacuum pump cannot be fully applicable to all working pressure ranges, but only according to Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements. For the convenience of use and the needs of various vacuum processes, sometimes various vacuum pumps are combined according to their performance requirements and applied as a unit.
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 main pumps essential for the application of vacuum process in various industries of national economy.
In recent years, along with the continuous high-speed development of China’s economy, vacuum pump related downstream application industries maintain rapid growth momentum, while in the vacuum pump application areas continue to expand and other factors under the joint pull, China’s vacuum pump industry has achieved a sustained and stable rapid development.
