Operating principle and capabilities:
The series HGL, HG pump is usually a sort of single-stage and single-cylinder rotary piston vacuum pump. It truly is significantly improved series H rotary piston pump and incorporates four patents; its common abilities have a good improvement.
Rotary piston vacuum pump is really a kind of vacuum manufacturing tools appropriate for pumping ordinary gases and condensable gases(when a fuel ballast applied). The pump must be fitted with ideal accessories if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display 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 changed repetitively, to ensure that pumping goal could possibly be attained.
The series HGL, HG pump may be a backing pump when mixed with a further higher vacuum pump too as operate singly. It’s broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so forth.
