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 contains four patents; its standard capabilities have a excellent improvement.
Rotary piston vacuum pump can be a kind of vacuum production gear ideal for pumping ordinary gases and condensable gases(when a gasoline ballast employed). 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 show 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 altered repetitively, in order that pumping goal can be attained.
The series HGL, HG pump is usually a backing pump when mixed with an additional large vacuum pump too as operate singly. It is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
