Operating principle and features:
The series HGL, HG pump is a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be enormously improved series H rotary piston pump and consists of 4 patents; its standard capabilities have a great improvement.
Rotary piston vacuum pump is usually a kind of vacuum manufacturing tools appropriate for pumping ordinary gases and condensable gases(when a fuel ballast utilized). The pump must be fitted with ideal accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in doing work 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 modified repetitively, to ensure pumping objective may very well be achieved.
The series HGL, HG pump is often a backing pump when combined with yet another high vacuum pump as well as operate singly. It is actually widely used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
