An Introduction to Vacuum Pump Units and Their Applications
Vacuum pump units are devices that combine vacuum pumps with corresponding vacuum components based on their performance requirements. These units are characterized by their compact structure and convenient installation and use.Vacuum pumping units can be categorized into low-vacuum units, medium-vacuum units, high-vacuum units, ultra-high-vacuum units, and oil-free vacuum units. The name of a vacuum unit is typically determined by its main pump, such as diffusion pump units, molecular pump units, etc.Low-Vacuum Pumping UnitsLow-vacuum pumping units operate within a pressure range of approximately 1330–100 Pa. Their main features include high working pressure and large exhaust volume, although their pumping speed is lower than that of medium- and high-vacuum units. These units are commonly used for rough pumping of vacuum chambers, as well as in vacuum conveying, vacuum impregnation, vacuum filtration, vacuum drying, and vacuum degassing (such as steel melt treatment) processes where th

Application of Vacuum Technology in Aerospace Industry
The main link closely related to vacuum science and aerospace technology comes from the simulation of space environment, because various spacecraft such as launch vehicles, artificial satellites, manned spacecraft, space stations, space probes, and space shuttles are all carried out in the natural vacuum of the universe during space flight.
