摘要
结合风机动叶调节原理及故障频发点的共性,对秦皇岛发电有限责任公司轴流风机运行中多发的动叶摆动故障进行总结分析,分析结果表明动叶调节的控制设备液压头及执行器故障是造成动叶摆动的原因,并提出了防范措施。
According to principle of adjustable rotating blade fan and common characteristics of faults occurred freguently, swing faults of rotating blade in axial-flow fan of Qinhuangdao Power Generation Co. Ltd. ,were analyzed and summarized. Results showed that malfunction of control system of hydraulic pump head and actuator caused swing faults of rotating blade. Meanwhile countermeasures were also put forward in this article.
