Working principle and features:
The series HGL, HG pump is really a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is enormously enhanced series H rotary piston pump and consists of four patents; its standard capabilities have a wonderful improvement.
Rotary piston vacuum pump is actually a sort of vacuum manufacturing products ideal for pumping ordinary gases and condensable gases(when a fuel ballast made use of). The pump needs to be fitted with suitable equipment if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in doing work 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 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, to ensure that pumping objective could be attained.
The series HGL, HG pump may be a backing pump when combined with a further high vacuum pump also as operate singly. It is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
