Operating principle and options:
The series HGL, HG pump is really a kind of single-stage and single-cylinder rotary piston vacuum pump. It is drastically improved series H rotary piston pump and consists of four patents; its basic capabilities possess a excellent improvement.
Rotary piston vacuum pump is often a kind of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(when a fuel ballast utilised). The pump need to be fitted with suitable accessories if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in doing work 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 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 transformed repetitively, to ensure that pumping goal may be accomplished.
The series HGL, HG pump is often a backing pump when combined with an additional higher vacuum pump likewise as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
