ROTARY PISTON VACUUM PUMPS

Working principle and options:
The series HGL, HG pump is really a sort of single-stage and single-cylinder rotary piston vacuum pump. It is actually considerably enhanced series H rotary piston pump and consists of four patents; its standard abilities possess a terrific improvement.
Rotary piston vacuum pump is a sort of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(whenever a fuel ballast applied). The pump should be fitted with proper add-ons if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in functioning 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 modified repetitively, so that pumping objective might be attained.
The series HGL, HG pump might be a backing pump when mixed with another large vacuum pump at the same time as operate singly. It is actually broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
