溪洛渡水电站离心泵电机温度偏高原因浅析

Analysis of the Abnormal High Temperature in Centrifugal Pump Motor in Xiluodu Hydropower Station

溪洛渡水电站技术供水系统自投运以来逐步出现离心泵电机温度过高、运行噪声偏大等问题。通过计算离心泵电机设计功率与实际功率之间的不同,分析离心泵电机温度过高的原因,并通过不同的试验方案,找出了最优的解决方案。

Since the operation of the technical water supply system in Xiluodu Hydropower Station, problems such as abnormal high temperature and large operating noise are observed in the centrifugal pump motor. The causes of the abnormal high temperature are analyzed by comparing the design power and the actual power of the motor. Then, the optimal treatment measure is obtained by different test schemes.
