Working principle and characteristics:
The series HGL, HG pump can be a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is significantly improved series H rotary piston pump and consists of 4 patents; its common capabilities have a excellent improvement.
Rotary piston vacuum pump can be a kind of vacuum manufacturing gear suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast employed). The pump need to be fitted with acceptable add-ons if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in functioning principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within 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 objective may be achieved.
The series HGL, HG pump might be a backing pump when combined with an additional substantial 
vacuum pump too as operate singly. It truly is extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
