Working principle and features:
The series HGL, HG pump is actually a form of single-stage and single-cylinder rotary piston vacuum pump. It truly is considerably improved series H rotary piston pump and includes 4 patents; its basic capabilities possess a good improvement.
Rotary piston vacuum pump is usually a type of vacuum production tools appropriate for pumping ordinary gases and condensable gases(whenever a gasoline ballast used). The pump should be fitted with suitable equipment if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in functioning 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 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 may very well be accomplished.
The series HGL, HG pump could be a backing pump when mixed with yet another higher vacuum pump at the same time as operate singly. It can be extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,etc.
