Operation principle show in functioning principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft in the housing. Piston pole can slide and swing freely in arch track. The whole pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are modified repetitively, so that pumping goal could be accomplished.
The series HGL, HG pump is usually a backing pump when combined with a different large vacuum pump likewise as operate singly. It truly is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
