Working principle and options:
The series HGL, HG pump can be a sort of single-stage and single-cylinder rotary piston vacuum pump. It is actually tremendously enhanced series H rotary piston pump and contains 4 patents; its common abilities have a excellent improvement.
Rotary piston vacuum pump is actually a type of vacuum production products appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast applied). The pump needs to 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 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 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 transformed repetitively, in order that pumping goal could be achieved.
The series HGL, HG pump is usually a backing pump 
when mixed with yet another large vacuum pump too as operate singly. It truly is widely used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
