Working principle and characteristics:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It can be significantly enhanced series H rotary piston pump and includes four patents; its general capabilities possess a good improvement.
Rotary piston vacuum pump is really a sort of vacuum production products appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast made use of). The pump must be fitted with proper add-ons if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in doing work 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 modified repetitively, in order that pumping goal might be attained.
The series HGL, HG pump might be a backing pump when mixed with a further substantial vacuum pump likewise as operate singly. It’s broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,etc.
