Working principle and options:
The series HGL, HG pump is actually a type of single-stage and single-cylinder rotary piston vacuum pump. It is actually greatly improved series H rotary piston pump and incorporates four patents; its standard capabilities possess a great improvement.
Rotary piston vacuum pump can be a type of vacuum manufacturing equipment ideal for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump should be fitted with appropriate accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in working 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, so that pumping objective can be achieved.
The series HGL, HG pump could be a backing pump when mixed with an additional substantial vacuum pump likewise as operate singly. It is actually broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
