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 greatly improved series H rotary piston pump and involves 4 patents; its general capabilities have a good improvement.
Rotary piston vacuum pump is actually a sort of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gasoline ballast employed). The pump needs to be fitted with ideal equipment 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 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 transformed repetitively, in order that pumping function can be attained.
The series HGL, HG pump is often a backing pump when combined with a different higher vacuum pump as well as operate singly. It is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
