| 摘 要： | 针对东深三期泵站轴流术式水泵叶片出现的裂纹，采用了有限元法对叶轮进行流体动力分析、结构刚强度与振动模态分析，并结合现场振动与压力脉动试验分析，判断叶片裂纹的成因，提出切割叶片出水边与轮比交点区的角和在叶片背面轮缘增加裙边的处理对策，取得了初步的效果。

| Abstract: | Due to the cracks of axial pump blades in Dongshen pump station, analysis on flow dynamics, structure strength and vibration for the pump runner, is finished by finite element method. Furthermore, the vibration and pressure fluctuation of the pump at site are measured. The measures are adopted such as cutting the sharp angles between the blades outlet and the runner hub, welding support bands with the edges of the suction side of the blades. The cracks are effectively prevented. |
