Operating principle and options:
The series HGL, HG pump can be a type of single-stage and single-cylinder rotary piston vacuum pump. It’s enormously improved series H rotary piston pump and includes 4 patents; its common capabilities have a great improvement.
Rotary piston vacuum pump is usually a kind of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump need to be fitted with ideal add-ons 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 changed repetitively, in order that pumping goal may be attained.
The series HGL, HG pump is usually a backing pump when combined with one more large vacuum pump likewise as operate singly. It is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
