ROTARY PISTON VACUUM PUMPS

Working principle and functions:
The series HGL, HG pump is actually a kind of single-stage and single-cylinder rotary piston vacuum pump. It truly is tremendously improved series H rotary piston pump and contains 4 patents; its common capabilities have a good improvement.
Rotary piston vacuum pump is actually a type of vacuum production gear ideal for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump have to be fitted with suitable accessories if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in doing work 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 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 transformed repetitively, to ensure pumping purpose could be accomplished.
The series HGL, HG pump is often a backing pump when mixed with another high vacuum pump as well as operate singly. It can be broadly used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
