The judging methods of best efficiency point and cavitation degrees of the pump were proposed. 提出了利用振动法识别泵最优工况点、判断空化的不同发展阶段的方法。
A minimum difference of head loss curves between design and off-design conditions appears in the vicinity of the best efficiency point of the pump. 在水泵最高效率点附近,设计工况与设计工况下水力损失的差值有最小值。
