煤矿主通风机振动故障预警装置的分析与应用

Analysis and Application of Vibration Fault Early Warning Device of Main Ventilation Fan in Coal Mine

王家岭煤业东回风井主通风机以往的故障预警装置只能对异常振动进行预警,无法对异常振动的强度大小进行预警,存在一定的安全隐患。针对性设计了一种新型故障预警装置,其可对通风机的异常振动及振动强度进行预警反馈,方便监控人员采取针对性预案,实践应用效果理想,具有较好的安全经济效益。

Wangjialing coal industry east back to the wind wells of the main ventilator failure warning device in the past can only be abnormal vibration over the line of warning,can not be abnormal vibration intensity size,there are certain safety hazards.Targeted design of a new type of fault warning device,ventilation fan abnormal vibration and vibration intensity of early warning feedback,to facilitate the monitoring staff to take targeted programs,the practical application of the effect is ideal,with better safety and economic benefits.
