摘　　要：本文主要对干熄焦循环风机在运行时水平振动及轴向振动逐渐加剧,致使不能正常运转维持生产。在利用状态检测诊断的手段做到提前预防,提前预知判断,对正在劣化的设备机构提前做检修处理,做到事先预防性维修,从而提高设备作业率。通常不平衡,是各种旋转机械中最普遍存在的故障。引起循环风机转子不平衡的原因是多方面的,如转子结构设计上不合理、机械加工时质量偏差、装配误差问题、材质不均匀、动平衡精度未达到标准;运行中联轴器找正相对位置的改变;转子部件缺损或磨损,如运行中由于腐蚀、磨损、介质不均匀产生结垢、耐磨层脱落等;转子受疲劳应力作用产线塑型变形转子的零部件(如叶轮、叶片、围带、拉筋、耐磨层等)局部损坏、脱落以及产生碎块飞出等。This article mainly focuses on the gradual increase of horizontal and axial vibrations during the operation of the dry quenching circulating fan,which leads to the inability to maintain normal operation and production.By utilizing state detection and diagnosis methods,we can achieve early prevention,advance prediction and judgment,and carry out maintenance and treatment of deteriorating equipment and mechanisms in advance,achieving preventive maintenance and improving equipment operation rates.Usually,imbalance is the most common fault in various rotating machinery.The causes of rotor imbalance in circulating fans are multifaceted,such as unreasonable rotor structure design,quality deviation during mechanical processing,assembly errors,uneven material,and failure to meet dynamic balance accuracy standards;Changes in the relative position of the coupling during operation;Defects or wear of rotor components,such as scaling caused by corrosion,wear,uneven media,and detachment of wear-resistant layers during operation;The components of the plastic deformation rotor in the production line,such as impellers,blades,shrouds,tension bars,wear-resistant layers,etc.,are locally damaged or detached due to fatigue stress,resulting in fragments flying out.
