First super - low specific - speed centrifugal pump has a long and narrow flow passage for its high head and low capacity , and the power absorbed by disc friction is too high , so the efficiency is very low ; secondly the diffusion of flow passage is so high , that the reserved flow often emerges at the inlet and outlet of impeller . therefore the h ~ q characteristic curve is often hump - shaped , and at the low - capacity operating condition the instability often occurs ; thirdly the centrifugal pump at high - capacity operating condition is easy to overload because the n ~ q curve appears a rising trend 首先由于它的扬程较高、流量较小，所以它的流道狭长，圆盘摩擦损失较大，效率相对较低；其次由于它的流道扩散较严重，易在叶片进口产生回流和在出口产生脱流，扬程流量特性曲线易出现驼峰，在小流量工况下易产生不稳定现象；第三，由于其功率流量曲线呈现上升趋势，在大流量区运行时电机易过载。
