Working principle and functions:
The series HGL, HG pump can be a sort of single-stage and single-cylinder rotary piston vacuum pump. It really is drastically improved series H rotary piston pump and includes four patents; its standard capabilities have a excellent improvement.
Rotary piston vacuum pump can be a kind of vacuum production products suitable for pumping ordinary gases and condensable gases(when a fuel ballast employed). The pump has to be fitted with ideal add-ons 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 function can be accomplished.
The series HGL, HG pump is usually a backing pump when mixed with a further higher vacuum pump likewise as operate singly. It’s extensively used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
