ROTARY PISTON VACUUM PUMPS

Working principle and options:
The series HGL, HG pump can be a kind of single-stage and single-cylinder rotary piston vacuum pump. It is considerably enhanced series H rotary piston pump and incorporates 4 patents; its basic abilities have a good improvement.
Rotary piston vacuum pump is often a kind of vacuum production products suitable for pumping ordinary gases and condensable gases(when a fuel ballast utilized). The pump needs to be fitted with suitable equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in functioning principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft in the housing. Piston pole can slide and swing freely in arch track. The entire pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are altered repetitively, to ensure pumping purpose might be achieved.
The series HGL, HG pump could be a backing pump when mixed with a different high vacuum pump also as operate singly. It really is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so on.
