Working principle and characteristics:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It truly is tremendously enhanced series H rotary piston pump and incorporates 4 patents; its basic capabilities have a wonderful improvement.
Rotary piston vacuum pump is usually a sort of vacuum production equipment appropriate for pumping ordinary gases and condensable gases(when a gas ballast applied). The pump have to be fitted with proper add-ons if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show 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 changed repetitively, to ensure that pumping objective may be achieved.
The series HGL, HG pump can be a backing pump when combined with yet another higher vacuum pump likewise as operate singly. It’s extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
