Working principle and capabilities:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It truly is drastically enhanced series H rotary piston pump and incorporates 4 patents; its common abilities have a excellent improvement.
Rotary piston vacuum pump is usually a type of vacuum manufacturing equipment suitable for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump must be fitted with ideal accessories if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working 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 changed repetitively, in order that pumping function may very well be accomplished.
The series HGL, HG pump can be a backing pump when combined with one more high vacuum pump also as operate singly. It truly is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
