The scroll vacuum pump evolved from the scroll compressor. Its structural principle was first invented by the French engineer Cruex in 1905, but due to technological limitations at the time, it was...
1. Raw Material Annealing (Primary Annealing)
Application Stage
Performed after the initial processing of raw materials (e.g., copper rods, plates via rolling, drawing, or casting) and before...
Rotary vane vacuum pumps are used as oil sealed pumps most of the time. During the use, some oil and gas will be expelled together with the pumped gas, resulting in oil spray. Therefore, rotary van...
The quality of vacuum pump oil depends on the viscosity and vacuum degree, and the vacuum degree depends on the value at different temperatures. The higher the temperature is, the more stable the v...
The rotary vane vacuum pump is an oil-sealed mechanical vacuum pump and is one of the most basic vacuum-acquiring devices in vacuum technology.
The rotary vane vacuum pump can pump out dry gases in...
