Working principle and functions:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It’s enormously improved series H rotary piston pump and consists of four patents; its common abilities possess a great improvement.
Rotary piston vacuum pump is a kind of vacuum manufacturing gear ideal for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump has to be fitted with proper add-ons if fuel is wealthy 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 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 modified repetitively, in order that pumping objective may very well be accomplished.
The series HGL, HG pump is often a backing pump when mixed with a further substantial vacuum pump also as operate singly. It can be extensively used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
