ROTARY PISTON VACUUM PUMPS

Operating principle and functions:
The series HGL, HG pump can be 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 abilities possess a great improvement.
Rotary piston vacuum pump is really a sort of vacuum manufacturing products ideal for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump has to be fitted with proper accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present 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 changed repetitively, to ensure that pumping objective could be accomplished.
The series HGL, HG pump is often a backing pump when combined with one more large vacuum pump likewise as operate singly. It is actually extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
