Working principle and attributes:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It’s significantly improved series H rotary piston pump and involves four patents; its general capabilities have a terrific improvement.
Rotary piston vacuum pump is often a kind of vacuum production equipment suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast employed). The pump must be fitted with ideal equipment if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in doing work 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 transformed repetitively, to ensure pumping purpose can be achieved.
The series HGL, HG pump is usually a backing pump when combined with a further higher vacuum pump too as operate singly. It is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
