摘　　要：利用正向推理,在能够引起引风机振动故障的全部原因中,采取逐个排除的方法,找出引风机轴向振动故障所在,分析了振动的机理,并从相位出发,就如何对此类故障进行诊断与分析进行了讨论,对诊断引风机振动故障和提高诊断准确率具有一定的指导意义。This paper uses forward inference with the method of removing one by one in all reasons of draft fan vibration fault to find out where the axial vibration fault in draft fan occurred. The mechanism of vibration is analyzed, and how to carry out diagnosis and analysis for this kind of fault from phase are discussed, which have certain guidance meaning for diagnosing vibration fault in draft fan and raising diagnosis accuracy rate.
