Working principle and attributes:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It can be significantly improved series H rotary piston pump and consists of 4 patents; its basic abilities possess a excellent improvement.
Rotary piston vacuum pump is a kind of vacuum production equipment ideal for pumping ordinary gases and condensable gases(when a gasoline ballast employed). The pump need to be fitted with acceptable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate 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 modified repetitively, to ensure pumping function can be accomplished.
The series HGL, HG pump may be a backing pump when mixed with a further large vacuum pump likewise as operate singly. It is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
