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.
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 measurements show that the airfoil blade fan prevails over the plate one in the aspects of total pressure efficiency, stable operation range and high efficient operation range.
