基于细化分析的风机故障诊断研究

Study of Ventilator Fault Diagnosis Based on Zooming Analysis

介绍了细化分析技术,利用细化分析的高频率分辨率特性对一风机的运行状态进行监测和诊断,分析出风机叶片、不对中及轴承几种的故障以及产生故障的原因。

The zooming analysis technology is introduced in this paper. By its characteristic of high frequency resolution, the running state of ventilator is monitored and diagnosed,and ventilator vane fault、shaft-misalignment、bearing fault and their causes are analyzed.
