Operating principle and characteristics:
The series HGL, HG pump is actually a form of single-stage and single-cylinder rotary piston vacuum pump. It truly is considerably enhanced series H rotary piston pump and incorporates four patents; its common capabilities possess a terrific improvement.
Rotary piston vacuum pump is a kind of vacuum production tools ideal for pumping ordinary gases and condensable gases(whenever a fuel ballast used). The pump should be fitted with appropriate add-ons if gasoline is wealthy 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 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 altered repetitively, to ensure pumping objective might be accomplished.
The series HGL, HG pump might be a backing pump when mixed with yet another substantial vacuum pump too as operate singly. It is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
