Working principle and attributes:
The series HGL, HG pump is a form of single-stage and single-cylinder rotary piston vacuum pump. It’s tremendously improved series H rotary piston pump and includes 4 patents; its basic capabilities possess a good improvement.
Rotary piston vacuum pump is a type of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a gas ballast used). The pump needs to be fitted with suitable accessories if gasoline is rich 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 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 transformed repetitively, so that pumping goal may be attained.
The series HGL, HG pump is usually a backing pump when mixed with yet another large vacuum pump as well as operate singly. It really is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
