Operating principle and options:
The series HGL, HG pump is a sort of single-stage and single-cylinder rotary piston vacuum pump. It is actually enormously improved series H rotary piston pump and consists of four patents; its general abilities possess a good improvement.
Rotary piston vacuum pump can be a sort of vacuum production tools suitable for pumping ordinary gases and condensable gases(when a gasoline ballast applied). The pump must be fitted with suitable accessories 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 inside the housing. Piston pole can slide and swing freely in arch track. The entire 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, so that pumping purpose may be achieved.
The series HGL, HG pump could be a backing pump when combined with one more large vacuum pump likewise as operate singly. It really is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
