Working principle and features:
The series HGL, HG pump is often a sort of single-stage and single-cylinder rotary piston vacuum pump. It’s greatly improved series H rotary piston pump and consists of four patents; its common abilities have a fantastic improvement.
Rotary piston vacuum pump is usually a type of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(when a fuel ballast employed). The pump needs to be fitted with suitable add-ons if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in operating 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 altered repetitively, in order that pumping function may very well be attained.
The series HGL, HG pump may be a backing pump when combined with a different large vacuum pump likewise as operate singly. It really is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
