ROTARY PISTON VACUUM PUMPS

Working principle and features:
The series HGL, HG pump is usually a sort of single-stage and single-cylinder rotary piston vacuum pump. It’s tremendously enhanced series H rotary piston pump and contains 4 patents; its common capabilities have a terrific improvement.
Rotary piston vacuum pump is a sort of vacuum production gear appropriate for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump must be fitted with acceptable add-ons if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in operating 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, in order that pumping objective could be accomplished.
The series HGL, HG pump can be a backing pump when mixed with one more high vacuum pump too as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
