Working principle and options:
The series HGL, HG pump is usually a sort of single-stage and single-cylinder rotary piston vacuum pump. It’s tremendously improved series H rotary piston pump and contains 4 patents; its general capabilities have a good improvement.
Rotary piston vacuum pump is a sort of vacuum production gear appropriate for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump needs to be fitted with acceptable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in operating 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 changed repetitively, in order that pumping objective can be accomplished.
The series HGL, HG pump is usually a backing pump when mixed with yet another high vacuum pump too as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
