Vacuum leak detection is the process of detecting the leak location and size of the vacuum system. Air leakage is the phenomenon in which gas flows from the high pressure side to the low pressure side through leaks or gaps in the system. False leakage is a physical phenomenon relative to real lea...

The screw vacuum pump is a common vacuum pump that is often used in the industrial field. It is recommended to add a valve between the screw vacuum pump and the pumped cavity, because most of the time the screw pump requires air/nitrogen/liquid purging, and the valve needs to be closed before pur...
