Operating principle and characteristics:
The series HGL, HG pump is often a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is significantly enhanced series H rotary piston pump and contains 4 patents; its standard capabilities have a excellent improvement.
Rotary piston vacuum pump is a sort of vacuum manufacturing equipment appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast utilised). The pump must be fitted with proper equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working 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 modified repetitively, to ensure pumping objective might be attained.
The series HGL, HG pump is often a backing pump when combined with a further substantial vacuum pump as well as operate singly. It is actually extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
