ROTARY PISTON VACUUM PUMPS

Operating principle and options:
The series HGL, HG pump is a type of single-stage and single-cylinder rotary piston vacuum pump. It is actually significantly enhanced series H rotary piston pump and consists of 4 patents; its standard abilities possess a wonderful improvement.
Rotary piston vacuum pump is usually a type of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump need to be fitted with acceptable accessories if gas is rich 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 within the housing. Piston pole can slide and swing freely in arch track. The whole 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 accomplished.
The series HGL, HG pump can be a backing pump when mixed with a further substantial vacuum pump likewise as operate singly. It can be extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
