Working principle and characteristics:
The series HGL, HG pump is actually a form of single-stage and single-cylinder rotary piston vacuum pump. It’s drastically enhanced series H rotary piston pump and contains 4 patents; its basic abilities have a terrific improvement.
Rotary piston vacuum pump is often a type of vacuum production products appropriate for pumping ordinary gases and condensable gases(whenever a gas ballast employed). The pump has to be fitted with proper add-ons if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display 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 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 function might be accomplished.
The series HGL, HG pump might be a backing pump when combined with a further high vacuum pump as well as operate singly. It is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so forth.
