考核水电设备运行稳定性的重要指标是振动及其引起的噪声。因为噪声源很多,引起的原因也各不相同。测量表明:并非负载越大,噪声越大。介绍了水电设备振动噪声的原因及其对策。
Important indicators for assessing the operational stability of hydropower equipment are vibration and the noise they cause. Because of the many sources of noise, the causes are different. Measurement shows that: not the greater the load, the greater the noise. The causes and countermeasures of vibration and noise of hydropower equipment are introduced.
