Operating principle and features:
The series HGL, HG pump is often a kind of single-stage and single-cylinder rotary piston vacuum pump. It is enormously improved series H rotary piston pump and consists of 4 patents; its standard abilities have a great improvement.
Rotary piston vacuum pump is actually a type of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump must be fitted with ideal equipment if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in doing work 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, in order that pumping function could be accomplished.
The series HGL, HG pump might be a backing pump when mixed with a further substantial vacuum pump also as operate singly. It truly is widely used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
