低比转速泵几何参数对扬程的影响，应当侧重于综合影响的研究。
The influences of geometrical parameters on low specific pump head should be emphasized on comprehensive influence.
低比转速泵的高扬程决定了叶片流道内逆压梯度比较高，这种压力分布使得水流易于在叶片表面脱流分离，这一现象甚至在泵的设计点也难以避免。
The high head produced by the impeller means high adverse pressure gradient within blade passage and because of this the flow often separates from the blade surfaces even at the design point.
解决泵行业一直依据经验统计值确定面积比而不能使低比转速离心泵在设计点效率最高这一问题。
