Operating principle and functions:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It’s tremendously enhanced series H rotary piston pump and incorporates four patents; its common abilities have a wonderful improvement.
Rotary piston vacuum pump is actually a type of vacuum production products ideal for pumping ordinary gases and condensable gases(whenever a gasoline ballast applied). The pump have to be fitted with proper equipment if fuel 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 within the housing. Piston pole can slide and swing freely in arch track. The entire 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, so that pumping function could be attained.
The series HGL, HG pump may be a backing pump when mixed with a different large vacuum pump too as operate singly. It really is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
