Working principle and functions:
The series HGL, HG pump is usually a sort of single-stage and single-cylinder rotary piston vacuum pump. It truly is significantly enhanced series H rotary piston pump and consists of four patents; its general capabilities have a great improvement.
Rotary piston vacuum pump is a type of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(whenever a gasoline ballast applied). The pump has to be fitted with ideal accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in doing work 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 modified repetitively, to ensure that pumping goal may very well be accomplished.
The series HGL, HG pump is usually a backing pump when combined with an additional large vacuum pump at the same time as operate singly. It is actually widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
