转炉ID风机振动故障分析与处理

Fault Analysis and Treatment of ID Fan Vibration of Converter

ID风机是转炉系统正常冶炼的关键设备之一。首先对该风机的故障过程及情况进行介绍,通过运用频谱分析法对振动异常进行分析,并经过动平衡分析计算,结合多次检修情况,逐一排查,最终确定其故障是由垫板与机架基础之间产生局部微变形和转子组主轴轴承安装轴段磨损所引起,并分别提出用研磨垫板、轴承座及机架基础和修复转子组主轴安装轴承轴段的处理措施,解决了ID风机振动大的故障,保证了转炉的正常生产。

ID fan is one of the key equipment in normal smelting converter system. This paper firstly introduces the failure process and conditions of ID fan. By using spectrum analysis method, this paper analyzes abnormal vibration. Through dynamic balance analysis and calculation, combined with several maintenance situation, this paper ultimately determines that the fault is produced by micro deformation between plate and frame base and rotor spindle bearing shaft section of wear and tear caused by installation, and puts forward treatment measures respectively with grinding plate, bearing, frame based group and spindle bearing segment repair of rotor shaft, which solves the fault of ID fan vibration and ensures the normal production of the converter.
