Operating principle and capabilities:
The series HGL, HG pump is a type of single-stage and single-cylinder rotary piston vacuum pump. It’s tremendously improved series H rotary piston pump and involves four patents; its general capabilities possess a excellent improvement.
Rotary piston vacuum pump is a sort of vacuum manufacturing equipment appropriate for pumping ordinary gases and condensable gases(when a gas ballast applied). The pump needs to be fitted with ideal 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 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 modified repetitively, to ensure pumping function can be attained.
The series HGL, HG pump may be a backing pump when mixed with yet another high vacuum pump at the same time as operate singly. It can be widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
