With the development of vacuum applications, the types of vacuum pumps have been developed in many ways, with pumping speeds ranging from a few tenths per second to hundreds of thousands and millions of liters per second. With the increasing requirements of vacuum technology in the field of production and scientific research, most of them need to be vacuum pumped by several vacuum pumps to meet the requirements of production and scientific research processes. The range of working pressures involved in the application department is very wide, so any type of vacuum pump cannot be fully applied to all working pressure ranges. Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements. . For ease of use and the needs of various vacuum processes, various vacuum pumps are sometimes combined according to their performance requirements for unit type applications.
Common vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. These pumps are essential for the application of vacuum processes in various industries of China's national economy. Kind. In recent years, with the sustained and rapid development of China's economy, the downstream application industry of vacuum pumps has maintained a rapid growth momentum. At the same time, with the continuous expansion of vacuum pump applications and other factors, China's vacuum pump industry has achieved sustained and rapid development.
