Operating principle and characteristics:
The series HGL, HG pump is actually a type of single-stage and single-cylinder rotary piston vacuum pump. It is actually tremendously enhanced series H rotary piston pump and contains 4 patents; its standard capabilities possess a great improvement.
Rotary piston vacuum pump is a type of vacuum production gear ideal for pumping ordinary gases and condensable gases(when a fuel ballast used). The pump have to be fitted with proper accessories if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in working 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 transformed repetitively, to ensure pumping function can be achieved.
The series HGL, HG pump could be a backing pump when mixed with a different higher vacuum pump too as operate singly. It truly is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so forth.
