With the historical development of vacuum pump, there are many kinds of vacuum pump models. The pumping speed of vacuum pump has changed from a few liters per second to hundreds of thousands or millions of liters per second.
With the vacuum technology in the field of production and scientific research, the pressure range of its application is becoming wider and wider. Most of them need several vacuum pumps to form a vacuum pumping system to pump together to meet the requirements of the production and scientific research process. Because the working pressure range of the vacuum application department is very wide, any type of vacuum pump can not be completely suitable For all working pressure ranges, only different types of vacuum pumps can be used according to different working pressure ranges and different working requirements.
In order to use conveniently and meet the needs of various vacuum processes, various vacuum pumps are sometimes combined according to their performance requirements and applied in the form of units.
Common vacuum pumps include dry screw vacuum pump, liquid ring pump, reciprocating pump, slide valve pump, rotary vane pump, roots pump and diffusion pump. These pumps are essential main pumps in the application of vacuum technology in various industries of national economy. In recent years, with the continuous and high-speed development of China’s economy, the downstream application industry related to vacuum pump has maintained a rapid growth momentum. At the same time, driven by the continuous expansion of the application field of vacuum pump and other factors, China’s vacuum pump industry has achieved sustained, stable and rapid development.
The historical development of vacuum pump is just as mentioned above. For more product introduction, please continue to pay attention.
