The equipment that can expel gas from a closed container or keep the number of gas molecules in the container decreasing is usually called vacuum obtaining equipment or vacuum pump. According to th...
After working for a long time on a Liquid ring vacuum pump, there will be some dirt on the outside or inside of the pump. In this case, we have to clean it. External cleaning is relatively easy, bu...
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...
When delving deeper into the differences between suction pumps and vacuum pumps, it becomes evident that despite some superficial similarities in their names, these two types of pumps exhibit disti...
I. Mechanical pumps
The main function of the mechanical pump is to provide the necessary pre-stage vacuum for the start-up of the turbomolecular pump. Commonly used mechanical pumps include mainly ...
The molecular pump is a vacuum pump that uses a high-speed rotor to transfer momentum to the gas molecules so that they gain directional velocity and are thus compressed, driven towards the exhaust...
