Operating principle and attributes:
The series HGL, HG pump is actually a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is enormously enhanced series H rotary piston pump and consists of four patents; its basic abilities possess a fantastic improvement.
Rotary piston vacuum pump is actually a sort of vacuum production tools ideal for pumping ordinary gases and condensable gases(whenever a gas ballast used). The pump must be fitted with appropriate accessories if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in operating 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 purpose can be accomplished.
The series HGL, HG pump can be a backing pump when mixed with an additional high vacuum pump likewise as operate singly. It really is widely used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
