Working principle and functions:
The series HGL, HG pump is a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be tremendously enhanced series H rotary piston pump and involves 4 patents; its standard abilities possess a wonderful improvement.
Rotary piston vacuum pump is actually a kind of vacuum manufacturing equipment suitable for pumping ordinary gases and condensable gases(whenever a gas ballast made use of). The pump should be fitted with acceptable equipment if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display 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, so that pumping purpose could be accomplished.
The series HGL, HG pump is often a backing pump when mixed with another high vacuum pump also as operate singly. It can be extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
