超超临界锅炉脱硫湿磨机异常振动的诊断

Diagnosis on Abnormal Vibration of Desulfurization Wet Mill in Ultra-Supercritical Boiler

某型超超临界锅炉脱硫湿磨机运行中出现了振动超标现象,影响了设备的安全运行。通过对设备振动的测试与分析,查明弹性联轴器中心不正是振动故障原因,调整后消除了振动故障。

The vibration beyond standard limit appears in the operation of a desulfurization wet mill in ultra - supercritica1 boiler, which affects the safe operation of equipment. By measurements and analysis of vibration, it is concluded that the misalignment of elastic coupling is the main reason for the vibration fault, and the vibration fault is eliminated by adjustment.
