Operating principle and capabilities:
The series HGL, HG pump is a form of single-stage and single-cylinder rotary piston vacuum pump. It is actually tremendously improved series H rotary piston pump and includes four patents; its common capabilities possess a fantastic improvement.
Rotary piston vacuum pump is often a type of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(when a fuel ballast applied). The pump needs to be fitted with appropriate accessories if gasoline is wealthy 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 within 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 modified repetitively, to ensure that pumping objective could possibly be accomplished.
The series HGL, HG pump might be a backing pump when combined with another higher vacuum pump likewise as operate singly. It is widely used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
