Working principle and characteristics:
The series HGL, HG pump is actually a form of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and involves four patents; its standard abilities possess a good improvement.
Rotary piston vacuum pump is usually a kind of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(whenever a gas ballast utilized). The pump needs to be fitted with suitable equipment if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in functioning 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 transformed repetitively, to ensure pumping purpose can be achieved.
The series HGL, HG pump may be a backing pump when combined with yet another large vacuum pump at the same time as operate singly. It is widely used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
