Working principle and capabilities:
The series HGL, HG pump is really a sort of single-stage and single-cylinder rotary piston vacuum pump. It is significantly improved series H rotary piston pump and consists of four patents; its basic capabilities have a fantastic improvement.
Rotary piston vacuum pump is actually a kind of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilized). The pump must be fitted with acceptable equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in functioning 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 changed repetitively, to ensure that pumping objective may very well be attained.
The series HGL, HG pump is usually a backing pump when mixed with an additional higher vacuum pump also as operate singly. It is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
