JOY10SC32-48B型梭车电气常见故障分析与控制探讨
|
摘要
回顾了JOY10SC32-48B型梭车在短壁机械化开采过程中的作用、结构特点、使用环境,介绍了该设备在使用过程中油泵电机无法启动、行走电机无法驱动电气方面2个常见典型故障,结合产品维修和维保实践经验,分别阐述了相应系统控制电路控制机理,详细分析了故障产生原因和判定方法、故障处理方法和注意事项,研究了降低电气系统故障率,应加强设备的日常巡检、完善元部件质量与装配工艺标准、提升元部件与整机设备性能测试、制定实际工况监测、监控及诊断方案的具体措施,揭示了对该型梭车维修管理、故障诊断方法、实践指导的现实意义。
The author reviews the role,structural characteristics and operating environment of JOY10 SC32-48 B shuttle car in short-wall mechanized coal mining,introduces two common typical faults,including oil pump motor start fault and walking motor drive electricity fault, and expounds the corresponding system control circuit combined with product repairing and maintenance respectively. The causes and judging methods,treatment methods and matters needing attention of the faults are analyzed in detail,and the reduction of the fault rate of the electrical system is studied. It is necessary to strengthen the routine inspection of the equipment,perfect the quality and assembly process standards of the components,improve the performance test of the components and the complete machine,and formulate the monitoring and control of the actual working conditions. It reveals the practical significance of maintenance management,fault diagnosis method and practical guidance for this type of shuttle.
