Working principle and attributes:
The series HGL, HG pump is really a sort 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 wonderful improvement.
Rotary piston vacuum pump is usually a kind of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(when a fuel ballast employed). The pump should be fitted with acceptable accessories if gas is wealthy 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 transformed repetitively, to ensure that pumping goal may be attained.
The series HGL, HG pump is often a backing pump when combined with a different high vacuum pump as well as operate singly. It is actually widely used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
