Working principle and characteristics:
The series HGL, HG pump is usually a form of single-stage and single-cylinder rotary piston vacuum pump. It really is considerably improved series H rotary piston pump and consists of 4 patents; its standard capabilities possess a great improvement.
Rotary piston vacuum pump is often a sort of vacuum production products appropriate for pumping ordinary gases and condensable gases(whenever a gasoline ballast made use of). The pump have to be fitted with appropriate equipment if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working 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 transformed repetitively, so that pumping purpose may be accomplished.
The series HGL, HG pump can be a backing pump when combined with a different substantial vacuum pump also as operate singly. It really is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
