The oil vapor of diffusion pump is completely move radially down the pump chamber. Due to random scattering or directional radiation, some molecules of steam ejected from the nozzle also move toward the pump port. This process we called Backflow. Backflow is the main contamination of diffusion pu...

Coupling alignment is also called finding a concentricity. After the pump and the motor are all installed, the last task is to find the pump and the motor to be concentric, that is, to align the pump and the axis of the prime mover on the same straight line so that it will not vibrate during oper...

The ballast valve can accelerate the extraction of steam without polluting the oil. If the rotary vacuum pump only pumping permanent gas, the gas does not liquefy due to the increase in pressure, so there is no deterioration of the pump oil. However, if the pump is used to vacuum dry or pumping h...
