Operating principle and options:
The series HGL, HG pump is a form of single-stage and single-cylinder rotary piston vacuum pump. It’s significantly enhanced series H rotary piston pump and incorporates 4 patents; its general capabilities have a good improvement.
Rotary piston vacuum pump is a kind of vacuum manufacturing equipment suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast applied). The pump need to be fitted with acceptable equipment if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in working 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 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 modified repetitively, in order that pumping goal may be achieved.
The series HGL, HG pump could be a backing pump when combined with a further large vacuum pump too as operate singly. It is actually extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
