Working principle and features:
The series HGL, HG pump is a type of single-stage and single-cylinder rotary piston vacuum pump. It is tremendously improved series H rotary piston pump and consists of four patents; its common abilities possess a fantastic improvement.
Rotary piston vacuum pump is actually a kind of vacuum manufacturing equipment ideal for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilized). The pump should be fitted with acceptable equipment if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show 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 transformed repetitively, so that pumping purpose may be achieved.
The series HGL, HG pump can be a backing pump when combined with another high vacuum pump as well as operate singly. It truly is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
