| Abstract: | The causes and aftereffect of axial thrust that rising from working impellers of single-suction high-pressure centrifugal fans is analyzed simply. By comparing the testing results of axial force produced by medium at impeller, main shaft and bearings before and after adding a disc blade on the experimental model fan, how the adding accessional blade can reduce axial thrust and the practical significant to the optimized reform of the product performance is showed. |
