Operating principle and options:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It truly is enormously enhanced series H rotary piston pump and consists of 4 patents; its general capabilities possess a fantastic improvement.
Rotary piston vacuum pump can be a type of vacuum production products suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast used). The pump must be fitted with acceptable accessories if gas 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 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 objective may be attained.
The series HGL, HG pump could be a backing pump when mixed with one more substantial vacuum pump likewise as operate singly. It is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
