Operating principle and functions:
The series HGL, HG pump is often a type of single-stage and single-cylinder rotary piston vacuum pump. It can be considerably enhanced series H rotary piston pump and incorporates four patents; its common abilities possess a terrific improvement.
Rotary piston vacuum pump is actually a sort of vacuum manufacturing products appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast used). The pump needs to be fitted with proper add-ons if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in working principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within 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 purpose could possibly be accomplished.
The series HGL, HG pump could be a backing pump when combined with a different higher vacuum pump likewise as operate singly. It truly is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
