Working principle and attributes:
The series HGL, HG pump is a kind of single-stage and single-cylinder rotary piston vacuum pump. It’s drastically enhanced series H rotary piston pump and consists of four patents; its general abilities possess a great improvement.
Rotary piston vacuum pump is really a type of vacuum production gear appropriate for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump must be fitted with appropriate accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate 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 transformed repetitively, so that pumping purpose can be accomplished.
The series HGL, HG pump is often a backing pump when mixed with an additional substantial vacuum pump likewise as operate singly. It really is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
