Working principle and characteristics:
The series HGL, HG pump can be a sort of single-stage and single-cylinder rotary piston vacuum pump. It really is significantly improved series H rotary piston pump and incorporates four patents; its general abilities possess a wonderful improvement.
Rotary piston vacuum pump is actually a type of vacuum manufacturing equipment ideal for pumping ordinary gases and condensable gases(whenever a gasoline ballast made use of). The pump need to be fitted with proper equipment if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in operating principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within 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 goal might be accomplished.
The series HGL, HG pump could be a backing pump when combined with a further large vacuum pump at the same time as operate singly. It truly is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
