Working principle and options:
The series HGL, HG pump can be a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be enormously improved series H rotary piston pump and incorporates four patents; its basic abilities possess a great improvement.
Rotary piston vacuum pump is really a kind of vacuum manufacturing equipment suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump has to be fitted with suitable equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present 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 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, so that pumping goal may be attained.
The series HGL, HG pump is often a backing pump when mixed with one more high vacuum pump at the same time as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
