Working principle and features:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It truly is tremendously enhanced series H rotary piston pump and includes 4 patents; its general capabilities have a great improvement.
Rotary piston vacuum pump is often a type of vacuum manufacturing products ideal for pumping ordinary gases and condensable gases(when a gasoline ballast applied). The pump should be fitted with proper add-ons if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in doing work 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 altered repetitively, so that pumping goal may very well be achieved.
The series HGL, HG pump is often a backing pump when mixed with another high vacuum pump at the same time as operate singly. It is actually extensively used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
