为了定量研究模型泵站水泵性能与进水口水力现象之间的关系，进行了模型试验。结果表明，当无因次水位（水位/管道管径：W/d）WL * ≥ 5. 46时，水位对泵性能的影响可以忽略，泵运行稳定。当WL *= 5.15时，泵的性能严重下降，无因次流量（标准工况下的实际流量/参考流量）Q * 可低至0.79，泵变得有噪声。最后，当WL *<5.15时，虽然叶轮仍在旋转，输入功率不变，但泵不再抽水。
In order to quantitatively study the relationship between the performance of a pump and the related hydraulic phenomena in a pump intake of a model pump station, a model test was carried out in the present paper. The results show that when the dimensionless water level (water level/diameter of the pipeline: W/d) WL*≥5.46, the influence of the water level on the performance of the pump can be ignored, and the operation of the pump is stable. When WL*=5.15, the performance of the pump decreases deeply, the dimensionless flow rate (actual flow rate/reference flow rate under standard working condition) Q* can be as low as 0.79, and the pump becomes noisy. Finally, when WL *<5.15, although the impeller is still rotating and the input power is unchanged, the pump no longer pumps water.
