洗煤厂振动筛故障诊断系统的设计及应用

Design and Application of Vibrating Screen Fault Diagnosis System in Coal Preparation Plant

针对振动筛工作负荷大、工况环境差、故障率较高且识别诊断难度较大的问题,基于洗煤厂大型直线振动筛的工作原理及故障类型的分析,设计了振动筛故障诊断系统整体方案。应用结果表明,该系统实现了信号采集、故障诊断、数据管理、故障预警等功能,实现了较好的技术及经济效益。

Aiming at the problems of large working load,poor working environment,high failure rate and difficult identification and diagnosis of vibrating screen,based on the analysis of working principle and fault types of large linear vibrating screen in coal preparation plant,the overall scheme of vibrating screen fault diagnosis system is designed and applied in practice,realizing the functions of signal acquisition,fault diagnosis,data management and fault early warning.Good technical and economic benefits have been achieved.
