600MW机组炉水循环泵电机故障处理及改进措施

Fault Treatment and Improvement of 600MW Boiler Water Circulation Pump Motor

针对600 MW亚临界机组锅炉炉水循环泵电机运行中发生故障的情况,从解体检查和现场检查两方面进行分析,认为上导向瓦工作面分层脱落是导致炉水循环泵电机振动大和异音的主要原因,提出改进导向瓦结构的处理措施,处理后炉水循环泵电机振动符合标准,异音消除。

For 600 MW subcritical units failure occurs in the operation of the boiler water circulating pump motor problem,from two aspects of the collapse of the inspection and on-site inspection is analyzed,the guide tile face layer falls off as lead to furnace water pump motor vibration and the main reason for the different sound,put forward treatment measures for the improvement of guide tile structure,furnace water pump motor vibration conforms to the standard after processing,different sound.
