寒冬压气站离心式压缩机振动故障诊断及预防措施

Vibration Fault Diagnosis and Preventive Measures of Centrifugal Compressor in Cold Winter

摘要: 介绍了离心式压缩机启机失败的诊断过程，用实例说明了故障诊断技术的应用。当通过故障诊断软件识别出的设备故障与实际故障不相符时，要改变视角，通过相互关联的外部条件查找故障原因并提出有效的解决措施。

Abstract: The diagnostic process of startup failure of centrifugal compressor was introduced. The applica-tion of fault diagnosis technology of centrifugal compressor was illustrated by using example. When the equipment fault identified by fault diagnosis software does not match the actual equipment fault situation, we should change the perspective and find out the cause of the fault through interrelated external conditions, and finally put forward effective solutions.
