Working principle and options:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It can be greatly improved series H rotary piston pump and includes 4 patents; its common abilities possess a fantastic improvement.
Rotary piston vacuum pump is usually a sort of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gasoline ballast made use of). The pump must be fitted with ideal add-ons if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in working 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 transformed repetitively, to ensure pumping objective can be achieved.
The series HGL, HG pump can be a backing pump when combined with an additional large vacuum pump as well as operate singly. It truly is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
