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...
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 primary objective of a vacuum pump is to generate, maintain, or improve a vacuum state within an enclosed space. By removing air or other gases, the vacuum pump reduces the pressure within the ...
A vacuum bellow is an axisymmetric tubular shell that whose bus bar is corrugated in shape and which has a certain bendability. Therefore it is also referred to as a flexible or flexural tube. Due ...
