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 ...
The following are some of the things that need to be noted during the use of the inline rotary vane vacuum pump. If one of them is used inadvertently, it will affect the service life of the vacuum ...
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...
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...
This week, I have compiled a list of some common vacuum terms to facilitate a better understanding of vacuum technology.
