Operating principle and attributes:
The series HGL, HG pump can be a sort of single-stage and single-cylinder rotary piston vacuum pump. It is actually considerably enhanced series H rotary piston pump and incorporates 4 patents; its general capabilities have a terrific improvement.
Rotary piston vacuum pump is usually a sort of vacuum manufacturing equipment ideal for pumping ordinary gases and condensable gases(when a fuel ballast applied). The pump should be fitted with suitable accessories if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in functioning 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 altered repetitively, to ensure that pumping purpose may be achieved.
The series HGL, HG pump might be a backing pump when mixed with a different large vacuum pump as well as operate singly. It truly is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
