Working principle and capabilities:
The series HGL, HG pump can be a kind of single-stage and single-cylinder rotary piston vacuum pump. It’s significantly improved series H rotary piston pump and consists of 4 patents; its standard capabilities possess a terrific improvement.
Rotary piston vacuum pump is usually a sort of vacuum production gear suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast applied). 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 show 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 altered repetitively, to ensure pumping function could possibly be accomplished.
The series HGL, HG pump is often a backing pump when combined with a different higher vacuum pump at the same time as operate singly. It is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
