Working principle and features:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It truly is greatly enhanced series H rotary piston pump and includes 4 patents; its general capabilities have a fantastic improvement.
Rotary piston vacuum pump can be a type of vacuum production equipment suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilized). The pump should be fitted with ideal equipment if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display 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 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, to ensure pumping goal may very well be attained.
The series HGL, HG pump may be a backing pump when mixed with a different substantial vacuum pump at the same time as operate singly. It is actually broadly used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
