Working principle and attributes:
The series HGL, HG pump is a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is drastically improved series H rotary piston pump and incorporates four patents; its general abilities have a excellent improvement.
Rotary piston vacuum pump is usually a kind of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a gasoline ballast employed). The pump must be fitted with acceptable accessories if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in functioning principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within 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 that pumping goal could possibly be attained.
The series HGL, HG pump is often a backing pump when combined with one more high vacuum pump likewise as operate singly. It is actually widely used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
