Working principle and features:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It really is enormously improved series H rotary piston pump and incorporates four patents; its common abilities have a wonderful improvement.
Rotary piston vacuum pump is actually a kind of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilised). The pump must be fitted with ideal add-ons if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present 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, to ensure that pumping objective could possibly be accomplished.
The series HGL, HG pump is usually a backing pump when combined with another large vacuum pump likewise as operate singly. It is actually widely used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
