Working principle and capabilities:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It really is drastically enhanced series H rotary piston pump and includes 4 patents; its basic abilities possess a good improvement.
Rotary piston vacuum pump can be a sort of vacuum manufacturing equipment suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast made use of). The pump need to be fitted with acceptable equipment if gas 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 inside 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 function could possibly be attained.
The series HGL, HG pump could be a backing pump when mixed with another substantial vacuum pump at the same time as operate singly. It truly is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
