300MW循环流化床锅炉双级动叶引风机常见故障原因分析及建议

Analysis and Suggestion on Common Faults of Double Stage Moving Blade Induced Draft Fan of 300 MW CFB Boiler

300MW循环流化床锅炉双级动叶引风机的常见故障是火电厂常见的问题之一,引风机联轴器的偏转、轴承磨损、油封损坏、油膜失稳和轴的挠曲变形等都会引起引风机的振动,因此需要提出有针对性的解决方案。通过对企业300 MW循环流化床锅炉双级动叶引风机的常见故障进行分析,并结合锅炉引风机在工作中的常见问题,详细分析了不同问题导致引风机振动的原因,并提出了有效的解决策略。

The common failure of the 300 MW circulating fluidized bed boiler two-stage moving blade induced draft fan is one of the common problems in thermal power plants. Deflection of the induced draft coupling, bearing wear, oil seal damage, oil film instability and shaft deflection will cause the vibration of the induced draft fan requires a targeted solution. By analyzing the common faults of the 300 MW circulating fluidized bed boiler two-stage moving blade induced draft fan, combined with the common problems of the boiler induced draft fan in the work, the reasons for the vibration of the induced draft fan caused by different problems were analyzed in detail, and the effective solution strategy were put forward.
