Operating principle and attributes:
The series HGL, HG pump is really a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is considerably enhanced series H rotary piston pump and includes 4 patents; its standard abilities have a fantastic improvement.
Rotary piston vacuum pump is really a sort of vacuum manufacturing products ideal for pumping ordinary gases and condensable gases(when a gas ballast used). The pump have to be fitted with appropriate accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show 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 goal might be accomplished.
The series HGL, HG pump may be a backing pump when mixed with another large vacuum pump as well as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so on.
