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...
Edwards has expanded its range of nEXT turbomolecular pumps with two larger models that provide faster pumping performance and excellent compression ratios for longer cycle times and lower ultimate...
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 ...
This series of Roots-type vacuum pumps cannot be used alone. It needs to be used in series with the pre-stage vacuum pump to increase the pumping rate of the pre-stage vacuum pump when the pressure...
I. Introduction of valve
Vacuum valve is a vacuum system component used to change the direction of airflow, adjust the size of gas flow, cut off or connect the pipeline in the vacuum system. The c...
