风机振动故障诊断综述

Survey on Faults diagnosis of Fan Vibration

在风机故障诊断中,采用的基本方法是时域监测、频域诊断,通过分析图谱来判断风机的工作状况及故障所在。主要介绍风机等旋转机械的故障机理、征兆提取、诊断推理以及国内外风机状态监测与故障诊断技术的发展现状和发展趋势。

The ways of the fault diagnosis of fan in enterprise almost are monitoring in time domain and making diagnosis in frequency domain. The working state and the faults are known by analyzing the figures. Ssome new developments in fault mechanism, signature extraction, diagnosis method , the actuality of the fan monitoring allover the world and the development in the future are introduced.
