ROTARY PISTON VACUUM PUMPS

Working principle and capabilities:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It can be drastically enhanced series H rotary piston pump and includes 4 patents; its basic capabilities have a good improvement.
Rotary piston vacuum pump is a kind of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast made use of). The pump need to be fitted with acceptable add-ons if fuel 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 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, to ensure that pumping objective may very well be achieved.
The series HGL, HG pump may be a backing pump when combined with one more higher vacuum pump as well as operate singly. It really is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
