Working principle and attributes:
The series HGL, HG pump is really a form of single-stage and single-cylinder rotary piston vacuum pump. It truly is greatly enhanced series H rotary piston pump and involves 4 patents; its general abilities possess a wonderful improvement.
Rotary piston vacuum pump can be a sort of vacuum production gear suitable for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump need to be fitted with appropriate equipment if fuel is wealthy 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 altered repetitively, to ensure that pumping objective may be attained.
The series HGL, HG pump is usually a backing pump when combined with yet another large vacuum pump likewise as operate singly. It truly is widely used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,etc.
