Working principle and attributes:
The series HGL, HG pump is actually a type of single-stage and single-cylinder rotary piston vacuum pump. It really is drastically enhanced series H rotary piston pump and includes four patents; its standard capabilities have a excellent improvement.
Rotary piston vacuum pump is actually a kind of vacuum production products suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilized). The pump has to be fitted with acceptable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present 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 whole 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 goal can be accomplished.
The series HGL, HG pump is usually a backing pump when combined with a further higher vacuum pump at the same time as operate singly. It’s extensively used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
