This paper explored the influence mechanism of the density, stiffness, damping, and acoustic properties of impeller materials on the vibration and noise of pumps. Combined with the measured data from typical pumping stations in hydropower engineering, the vibration and noise performance of pumps with different material impellers was analyzed, providing a theoretical basis for pump noise reduction design and material selection.

水泵作为流体输送的动力设备，广泛应用于农业灌溉、城市供水、工业循环等领域，但水泵运行中产生的振动噪声不仅影响设备使用寿命，还会对周围环境造成污染，降低操作人员的工作舒适度。叶轮作为水泵能量转换的核心部件，其材料特性直接决定了水泵的振动噪声特征，其中：材料密度影响转子系统的固有频率分布，材料刚度决定叶片在流体激励下的变形响应，材料阻尼特性控制振动能量的耗散速率，材料声学特性影响声波的辐射效率。本文探讨了叶轮材料的密度、刚度、阻尼及声学特性对水泵振动噪声的影响机制，结合景电工程典型泵站的实测数据，分析了不同材质叶轮的振动噪声表现，为水泵降噪设计与材料选择提供理论依据。
