ROTARY PISTON VACUUM PUMPS

Working principle and capabilities:
The series HGL, HG pump is often a sort of single-stage and single-cylinder rotary piston vacuum pump. It is tremendously improved series H rotary piston pump and incorporates 4 patents; its basic capabilities possess a wonderful improvement.
Rotary piston vacuum pump is usually a sort of vacuum manufacturing products appropriate for pumping ordinary gases and condensable gases(when a fuel ballast utilized). The pump should be fitted with acceptable add-ons if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in working principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft inside 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 modified repetitively, to ensure pumping function could possibly be attained.
The series HGL, HG pump may be a backing pump when combined with another high vacuum pump too as operate singly. It is actually widely used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
