摘　　要：某厂化工装置热油炉风机首次单机试运行时,因径向推力轴承异常磨损导致风机无法正常使用。详细分析了故障产生的原因,设计了一个平衡轴向力的轴承箱,使作用在原径向推力轴承上的轴向力得以移出。运用新增轴承箱与原风机轴系能较好自对中的特性,通过增设承载支座调整平台,使设计方案得以成功实施,消除了风机径向推力轴承异常磨损的故障。Due to abnormal wear of radial thrust bearing,the thermal oil boiler fan did not work properly at first individual equipment commissioning in a chemical plant.The breakdown reasons was analyzed in detail,and a individual bearing housing for balancing axial force was designed to creatively remove the axial force acting on the original radial thrust bearing.During the construction process,this design skillfully used the character of the new bearing housing and the original shaft automatically alignment well.Through additional support bearing adjustment platform,the design has been successfully implemented,and ultimately resolved satisfactorily fan abnormal wear and tear of the radial thrust bearing failure.
