Working principle and characteristics:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It is considerably improved series H rotary piston pump and involves 4 patents; its standard abilities have a good improvement.
Rotary piston vacuum pump is really a type of vacuum manufacturing tools suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast made use of). The pump should be fitted with ideal equipment if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in operating 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 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 altered repetitively, to ensure pumping goal may be achieved.
The series HGL, HG pump is usually a backing pump when mixed with a different high vacuum pump likewise as operate singly. It really is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
