摘　　要：为保证石圪台煤矿旋转类设备的可靠安全运行,对矿用旋转类设备故障原因进行分析。矿用设备运行环境差和长期高负荷运行是其故障的主要原因。采用在线监测的方式对设备的振动信号进行监测,通过数据采集、处理及分析几个阶段评估设备潜在的故障及其运行状态。采用加速度传感器对高频(2~20 000 Hz)和低频(2~2 000 Hz)加速度信号进行数据采集。矿用旋转设备状态监测系统采用C/S架构,由11个采集站实现对除采煤机外的所有主要旋转类设备的监测。现场应用表明:监测系统可以有效避免设备的非计划停机,延长设备的使用寿命,保证了设备的使用效率。In order to ensure the reliable safe operation of the rotating equipment in Shigetai coal mine,the failure reasons of coal mine rotating equipment were analyzed. The bad operation environment and long-term high load operation of mining equipment are the major causes of the failure. Monitor the vibration signal of equipment with the method of on-line monitoring. Through several stages of data collection,processing and analysis, evaluate the potential fault and its running state of equipment. The acceleration sensor was adopted to high frequency(2~20 000 Hz) and low frequency(2~2 000 Hz) acceleration signal for data collection. The condition monitoring system of mine rotating equipment adopts C/S structure. All major rotating equipments except the shearer are monitored by 11 acquisition stations.The field application show that the monitoring system can effectively avoid the unplanned shutdown of the equipment,extend the service life of the equipment,and ensure the service efficiency of the equipment.
