Operating principle and functions:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It is actually significantly improved series H rotary piston pump and contains 4 patents; its standard capabilities have a fantastic improvement.
Rotary piston vacuum pump is often a sort of vacuum production products suitable for pumping ordinary gases and condensable gases(when a 
fuel ballast utilised). The pump need to be fitted with acceptable equipment if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in operating 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 altered repetitively, in order that pumping goal may very well be accomplished.
The series HGL, HG pump can be a backing pump when combined with an additional substantial vacuum pump too as operate singly. It truly is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
