摘　　要：转炉煤气回收系统一次除尘风机改造完成后,对风机进行了试机,当风机转速在1150r/min以下时,轴向振动基本随转速呈线性增加;转速超过1200r/min后轴向振动呈非线性增加,振动值严重超标。分析与排查结果表明,除尘风机轴向振动偏大的根本原因是新轴承座强度偏低、轴承箱结构单薄引起的。采取相应措施后,问题圆满得到解决。After the transformation of the dust removal fan of the converter gas recovery system is completed, tested the fan. When the fan speed was below 1150 r/min, the axial vibration basically increases with the speed.When the speed exceeds 1200 r/min, the axial vibration increases non-linearly, and the vibration value exceeds the standard seriously.Analysis and investigation results show that, the root cause of the large axial vibration of the dust removal fan is the low strength of the new bearing seat and the thin structure of the bearing box.After taking corresponding measures, the problem was satisfactorily resolved.
