Working principle and characteristics:
The series HGL, HG pump is often a type of single-stage and single-cylinder rotary piston vacuum pump. It can be drastically enhanced series H rotary piston pump and incorporates 4 patents; its standard capabilities possess a excellent improvement.
Rotary piston vacuum pump is a sort of vacuum manufacturing equipment suitable for pumping ordinary gases and condensable gases(whenever a gas ballast utilized). The pump needs to be fitted with ideal equipment if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display 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 transformed repetitively, in order that pumping goal might be attained.
The series HGL, HG pump is usually a backing pump when mixed with an additional high vacuum pump too as operate singly. It is actually extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
