| 摘 要： | 水泵吸水池内的流动状况严重影响着水泵的运行,特别是某些流动形式如不均匀流、流速梯度较大的剪切流等会导致水泵进水口各种旋涡的生成,甚至产生空化、振动现象,从而降低泵站效率。本文用2D-PIV系统对水泵吸水池的不对称流动进行了测量,通过图像处理技术的分析,得到了吸水池自由液面高度的平均分布,揭示了不对称流动等因素对吸水池内流动状况的影响。

| Abstract: | the flow situations in the open pump influence the performance of pump system greatly. Especially non-uniform flow can induce the generation of various vortices, cavitation and vibration, and even decrease the pump efficiency. In this paper, the non-uniform flow in the open pump sump was measured by the 2D PIV system. The height distribution of free water surface was obtained by image processing technology, which showed the influence of non-uniform flow on the flow situations in pump sump. |
