Operating principle and functions:
The series HGL, HG pump is a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is drastically improved series H rotary piston pump and includes four patents; its common capabilities have a wonderful improvement.
Rotary piston vacuum pump is really a type of vacuum manufacturing gear suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilized). The pump has to be fitted with acceptable add-ons 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 in 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 modified repetitively, to ensure pumping goal could be accomplished.
The series HGL, HG pump might be a backing pump when combined with an additional high vacuum pump too as operate singly. It really is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so forth.
