Operating principle and capabilities:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It can be enormously enhanced series H rotary piston pump and includes 4 patents; its common capabilities possess a good improvement.
Rotary piston vacuum pump is a type of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilised). The pump have to be fitted with appropriate accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in working 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, to ensure pumping function may very well be achieved.
The series HGL, HG pump can be a backing pump when combined with another higher vacuum pump too as operate singly. It really is extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
