ROTARY PISTON VACUUM PUMPS

Working principle and options:
The series HGL, HG pump can be a sort of single-stage and single-cylinder rotary piston vacuum pump. It truly is significantly improved series H rotary piston pump and contains 4 patents; its standard abilities possess a fantastic improvement.
Rotary piston vacuum pump can be a kind of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a fuel ballast applied). The pump must be fitted with suitable add-ons if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in doing work principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft inside 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, in order that pumping function may be attained.
The series HGL, HG pump may be a backing pump when mixed with a further substantial vacuum pump as well as operate singly. It is extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
