摘要
为实时监测选煤厂振动筛的工作状态,及时准确发现设备故障,降低现场人工巡检的劳动强度,在振动筛筛体上设置三轴加速度传感器,采集振动筛实施工况数据智能分析进行实时状态监测。传感器可准确采集筛体X、Y、Z轴3个方向振动加速度参数,由智能诊断软件对其进行滤波、傅里叶变换及速度包络分析等,结合实际振动筛参数建立筛体的振动状态模型,并在设备平台形成包络值趋势图。振动筛筛体出现异常时,自有云诊断系统及时判断故障以及故障发生的准确位置,并向维护人员发送预警信息,极大提高振动筛故障诊断的效率及现场工作人员的安全性。经现场应用验证,振动筛的故障检出率及时效性均得到较大提升,促进了选煤厂生产实践的自动化、智能化。
In order to real-time monitor the working situation of vibrating screen find the equipment failure accurately,and reduce the labor intensity of the manual inspection on site,the real-time status monitoring was carried out by setting the three-axis acceleration sensor to collect the intelligent analysis of vibrating screen.The sensor can accurately collect the vibration acceleration parameters in the three directions of X,Y and Z axes of the screen body,and the intelligent diagnosis software will filter,Fourier transform and velocity envelope analysis,etc.The envelope value trend graph on the equipment platform was formed by establishing the vibration state model of the screen body in combination with the actual vibrating screen parameters.When the vibrating screen body is abnormal,the free cloud diagnostic system will judge the fault and the exact location of the fault in time,and send early warning information to the maintenance personnel,which greatly improves the efficiency of the vibrating screen fault diagnosis and the safety of the field staff.The fault detection rate of vibrating screen and its timeliness have been greatly improved by field application verification.It has a positive effect on the automation and intelligence of the production practice of coal preparation plant.
