Operating principle and options:
The series HGL, HG pump can be a type of single-stage and single-cylinder rotary piston vacuum pump. It is enormously improved series H rotary piston pump and includes 4 patents; its general capabilities have a great improvement.
Rotary piston vacuum pump is usually a type of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a fuel ballast utilized). The pump need to be fitted with appropriate accessories if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in operating 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 altered repetitively, in order that pumping goal may be attained.
The series HGL, HG pump can be a backing pump when combined with one more large vacuum pump at the same time as operate singly. It’s broadly used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
