介绍对立式和卧式两种轴流泵模型装置进行的飞逸转速特性试验研究,试验结果表明在-6°～+6°叶片角范围内,单位飞逸转速随叶片角度减小而增加,飞逸转速随扬程提高而增加,飞逸转速是额定转速的0.83～1.4倍。
The experimental study on runaway speed characteristics of two axial flow pump model devices is presented. The experimental results show that the unit runaway speed increases with the decrease of the vane angle within the range of -6 ° ~ + 6 ° blade angle , Runaway speed increases with lift headway, runaway speed is 0.83 to 1.4 times the rated speed.
