摘要
某5 000t/d水泥熟料生产线高温风机存在驱动端轴承轴向振动加剧的问题.介绍了振动故障检测技术的诊断流程,通过采用多通道振动分析仪检测技术,确定了高温风机、电机和风机驱动端、非驱动端水平、垂直、轴向等12个振动检测点位置,采集了各检测点振动速度并生成频谱图.通过频谱分布诊断分析,高温风机驱动端轴向振动大主要是由风压背压拍击及水泥基础初期开裂等生产工艺原因所致,拆除部分百叶阀、更换窑尾袋收尘器滤袋后,高温风机驱动端轴承轴向振动值恢复正常.
Abstract
There is a problem of intensified axial vibration of the drive end bearing in the high-temperature fan of a 5 000t/d cement clinker production line.The diagnostic process of vibration fault detection technology is introduced.By using a multi-channel vibration detection analyzer detection technology,12 vibration detection points,including the high-temperature fan,motor,and fan drive end,non-drive end horizontal,vertical,and axial positions,were determined.The vibration rates of each detection point were collected and a frequency spectrum was generated.Through spectrum distribution diagnosis analysis,it is found that the large axial vibration at the driving end of the high-temperature fan is mainly caused by production process reasons such as wind pressure back pressure impact and initial cracking of the cement foundation.After removing some louver valves and replacing the filter bag of the kiln tail bag dust collector,the axial vibration value of the bearing at the driving end of the high-temperature fan returned to normal.
