Operating principle and features:
The series HGL, HG pump can be a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be considerably improved series H rotary piston pump and includes 4 patents; its common capabilities have a wonderful improvement.
Rotary piston vacuum pump is really a sort of vacuum production equipment appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast employed). The pump needs to be fitted with proper equipment if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in working 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 altered repetitively, to ensure pumping goal may very well be attained.
The series HGL, HG pump is often a backing pump when combined with yet another higher vacuum pump at the same time as operate singly. It can be broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so on.
