正确识别转动设备轴承金属温度异常及轴承故障

Identification of Rotating Equipment Bearing Metal Temperature Anomaly of Authenticity for Correct Diagnosis for Bearing Fault

针对某机组一次因非计划停运事件所暴露出轴承温度保护误动问题,根据本人长期从事汽轮机专业工作所积累的经验,总结分析测量设备故障和机务设备故障所具有的不同的特征和规律,提出判别金属温度异常的真伪的方法,以便为改进完善轴承金属温度保护提供参考依据。也可以抛砖引玉,用类似的方法来判别其他测量参数的异常情况,为开展设备状态检测工作开拓新思路。

For one unit at a time for unscheduled shutdown incident has exposed the bearing temperature protection misoperation problem. According to my long - term professional work experience for the steam turbine, the Summary analysis has been made for measurement equipment failure and maintenance equipment have different characteristics and laws, it presents the method of judging the authenticity of a metal temperature bearing anomaly. In order to provide reference for improved metal temperature protection, and the author use a similar approach to identifying other measuring parameters of the abnormal situation, exploring a new way of thinking for equipment state inspection working.
