Operating principle and functions:
The series HGL, HG pump is often a type of single-stage and single-cylinder rotary piston vacuum pump. It can be tremendously improved series H rotary piston pump and incorporates 4 patents; its basic abilities possess a terrific improvement.
Rotary piston vacuum pump is really a type of vacuum production gear suitable for pumping ordinary gases and condensable gases(when a gasoline ballast applied). The pump should be fitted with suitable add-ons if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in operating 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 that pumping purpose may very well be attained.
The series HGL, HG pump is usually a backing pump when mixed with another substantial vacuum pump at the same time as operate singly. It can be extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
