Working principle and options:
The series HGL, HG pump is a form of single-stage and single-cylinder rotary piston vacuum pump. It really is drastically enhanced series H rotary piston pump and includes 4 patents; its standard capabilities possess a terrific improvement.
Rotary piston vacuum pump is really a sort of vacuum manufacturing equipment appropriate for pumping ordinary gases and condensable gases(whenever a gas ballast utilized). The pump has to be fitted with appropriate add-ons if fuel is rich 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 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 transformed repetitively, to ensure that pumping function could possibly be achieved.
The series HGL, HG pump may be a backing pump when combined with an additional large vacuum pump likewise as operate singly. It is widely used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
