Operating principle and capabilities:
The series HGL, HG pump is really a form of single-stage and single-cylinder rotary piston vacuum pump. It is actually drastically improved series H rotary piston pump and involves 4 patents; its common abilities possess a excellent improvement.
Rotary piston vacuum pump is actually a sort of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump have to be fitted with appropriate add-ons if fuel is rich 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 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 changed repetitively, in order that pumping function could be attained.
The series HGL, HG pump may be a backing pump when mixed with one more substantial vacuum pump likewise as operate singly. It is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
