基于故障检测次序的供料单元故障诊断

针对气动PLC自动生产线中供料单元,在一次供料过程时,上电后却无法运作,通过观察其故障现象,分析其故障原因,提出设定故障检查次序,综合利用假设验证法、替换法、经验法和测量法等故障诊断方法,排除设备的故障,继而通过实践证明合理设定故障检查次序对设备故障排除的重要性.

Feeding unit fault diagnosis based fault detection order

According to the PLC pneumatic automatic production line feeding unit, in a feeding process, feeding unit cannot op eration after powering, through the observation of the phenomenon, analyzing the fault reason,puts forward setting fault check order, comprehensive utilization of hypothesis testing method, replacement method, experience method and measuring method of fault di agnosis method, rules out the failure of equipment.it is proved by practice the importance of rational setting fault check order to ex clude the equipment fault.
