Operating principle and options:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It’s greatly enhanced series H rotary piston pump and includes four patents; its basic capabilities have a good improvement.
Rotary piston vacuum pump is actually a kind of vacuum manufacturing tools appropriate for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump needs to be fitted with suitable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in operating 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 changed repetitively, to ensure pumping objective could possibly be attained.
The series HGL, HG pump could be a backing pump when mixed with a different substantial vacuum pump also as operate singly. It truly is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
