ROTARY PISTON VACUUM PUMPS

Operating principle and options:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It’s drastically enhanced series H rotary piston pump and incorporates 4 patents; its general capabilities have a excellent improvement.
Rotary piston vacuum pump is actually a sort of vacuum production equipment ideal for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump has to be fitted with proper accessories if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in functioning 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 modified repetitively, to ensure that pumping objective may be attained.
The series HGL, HG pump may be a backing pump when combined with an additional substantial vacuum pump too as operate singly. It is actually broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so on.
