摘　　要：为了研究同一比转数轴流泵在工程中应用的适应性,依托淮河入海水道二期工程宋潮站的设计参数,采用了等流量加大扬程的选型方法初步选型,基于同一比转数轴流泵(TJ04-ZL-11,ZM60A)分别进行装置模型试验研究,对比分析了泵装置的能量、空化、飞逸等方面性能.结果表明,TJ04-ZL-11水力模型泵装置在叶片角度为0°、泵装置设计扬程为4.61 m时,效率为73.04%;在泵装置最高扬程为8.42 m时,效率为66.17%.ZM60A水力模型泵装置在叶片角度为0°、设计扬程为4.61 m时,效率为73.96%;在泵装置最高扬程8.42 m时,效率为71.14%.空化试验结果表明,ZM60A水力模型空化性能要比TJ04-ZL-11号水力模型空化性能更好.ZM60A水力模型飞逸特性与TJ04-ZL-11号水力模型飞逸特性相比差别不大.同一比转数的轴流泵在性能方面仍存在差异,在宽扬程运行范围的工程应用中需要兼顾空化、飞逸等多方面性能进行选型.研究结果对类似工程的水泵选型具有一定的参考价值.In order to study the adaptability of axial-flow pumps with the same specific speed in engineering applications,supported by the design parameters of the Songchao Station of the Huaihe River Estuary Waterway PhaseⅡProject,the preliminary pump selection method of equal flow rate and head increase was adopted to carry out the device model test based on the axial-flow pumps(TJ04-ZL-11,ZM60A)with the same specific speed,respectively.The performance of the pumping device in terms of energy,cavitation,and runaway was compared and analyzed.The results show that when the blade placement angle of the TJ04-ZL-11 hydraulic model is 0°and the pumping device head is 4.61 m,the efficiency of the pumping device is 73.04%.When the maximum head is 8.42 m,the efficiency of the pumping device is 66.17%.When the blade placement angle of the ZM60A hydraulic model is 0°and the pumping device head is 4.61 m,the efficiency of the pumping device is 73.96%,and when the maximum head is 8.42 m,the efficiency of the pumping device is 71.14%.Cavitation test results show that the ZM60A hydraulic model cavitation performance is better than the TJ04-ZL-11 hydraulic model cavitation performance.There is little difference in the runaway performance of the ZM60A hydraulic model and the TJ04-ZL-11 hydraulic model.Axial-flow pumps with the same speci-fic speed still have differences in performance,so it is important to consider various aspects of perfor-mance such as cavitation and runaway when selecting axial-flow pumps for engineering applications.This research has certain reference value for water pump selection in similar projects.
