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...
Many vacuum process installations are equipped with a Roots pump on top of the pre-stage pump, both to increase the pumping speed and to improve the vacuum. However, the following problems are ofte...
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...
