Operating principle and functions:
The series HGL, HG pump is a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is considerably improved series H rotary piston pump and includes four patents; its common capabilities have a good improvement.
Rotary piston vacuum pump is usually a sort of vacuum manufacturing products ideal for pumping ordinary gases and condensable gases(when a gas ballast utilized). The pump must be fitted with acceptable equipment if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show 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 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 objective could be achieved.
The series HGL, HG pump is often a backing pump when mixed with yet another large vacuum pump at the same time as operate singly. It’s extensively used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
