摘要
高速线材厂轧机具有运转速度高、载荷变化频繁、所轧制轧件温度低的特点,设备的主要故障是主传动设备的轴承、齿轮失效故障,占总设备故障时间的50%以上。以某高速线材厂的一台预精轧机为研究对象,对其状态进行监测,并根据得到的频谱图进行故障诊断。现场实际检查结果与诊断结果基本一致,说明:将设备状态监测与故障诊断技术应用于高速线材轧机,能达到预防为主的目的,有效避免了过维修和欠维修,既减少了设备故障又降低了维修费用,大大提高了作业率,为生产的顺利进行提供了可靠的保障。
With the features of high running speed, high frequency of load change and low roiling temperature of roll piece, the high-speed wire rod mill device's main faults are focused on the bearing failure and gear failure of main driving equipments, which account for above 50 percent of total fault time. Taking a pre-finishing mill in a high-speed wire rod mill factory as a research object, its condition was monitored and fault diagnosis was made according to the obtained spectrum. The on-site practical inspection results were basically in consistent with the diagnosis results. It is indicated that to apply the technology of equipment condition monitoring and fault diagnosis to high-speed wire rod mill, the purpose of prevention is achieved, the over and less maintenance are effectively avoided. Not only equipment failures are reduced, but also the maintenance cost is reduced. The operating rate is improved greatly. It provides a reliable guarantee for smooth production.
