Working principle and capabilities:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It is actually significantly enhanced series H rotary piston pump and involves 4 patents; its general abilities possess a terrific improvement.
Rotary piston vacuum pump is really a kind of vacuum manufacturing products appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast employed). The pump has to be fitted with proper accessories if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within 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 altered repetitively, to ensure that pumping objective may very well be achieved.
The series HGL, HG pump is usually a backing pump when mixed with an additional higher vacuum pump at the same time as operate singly. It’s extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
