摘要
对2台焦化风机进行了振动测试,通过对比2台风机的振动大小、波形、频谱,诊断出其中一台风机增速器存在对中不良,诊断结果经现场验证得到证实,经过处理后振动恢复正常。确保该风机能够长时间的安全可靠运行。本诊断方法可用于其他同类机组的现场问题处理中。
Carrying out the vibration test on two cocking fans, by comparing the vibration, waveformand spectrum of the two fans, diagnosing one fan speed increaser with bad centring, this diagnosis result was confirmed through field test. The vibration got right after being processed, it can ensure the fanruns safely and reliably for a long time. This diagnosis method can be used to other similar sets in processing the field problem.
