Role: pumping out gas molecules from the vacuum chamber, reducing the gas pressure inside the vacuum chamber to achieve the required vacuum level. Uses: vacuum pumps are widely used in petrochemical, energy, metallurgical manufacturing, food processing industry and other fields.
Vacuum pump is a kind of equipment used to generate and maintain vacuum, which is widely used in various industrial, scientific research and medical fields. The main function of the vacuum pump is to pump out the gas inside the container, thus creating a vacuum environment below atmospheric pressure. This vacuum environment can be used in a variety of experimental, production and manufacturing processes, such as semiconductor manufacturing, vacuum cooling, vacuum drying, vacuum distillation, vacuum packaging and so on.
Vacuum pumps play a vital role in semiconductor manufacturing. Semiconductor manufacturing needs to be carried out at very low pressures to avoid the effects of impurities and gases on semiconductor devices. Vacuum pumps can pull gases out of the manufacturing chamber to produce a highly pure manufacturing environment. In addition, vacuum pumps can be used in the testing and packaging of semiconductor devices to ensure device quality and stability.
History of Development
With the development of vacuum applications, a wide variety of vacuum pumps have been developed, with pumping speeds ranging from a fraction of a liter per second to hundreds of thousands and millions of liters per second. With the vacuum technology in the field of production and scientific research on the application of the pressure range of the requirements of the wider and wider, most of the need for several kinds of vacuum pumps composed of vacuum pumping system *** with the pumping in order to meet the requirements of the production and scientific research process.
Because of the wide range of working pressures involved in the vacuum application sector, any one type of vacuum pump cannot be completely suitable for all working pressure ranges, and can only be used according to different working pressure ranges and different working requirements, using different types of vacuum pumps. For the convenience of use and the needs of various vacuum processes, sometimes various vacuum pumps are combined according to their performance requirements to be applied in unit type.
