汽轮发电机组的现场摩擦故障诊断

Site diagnosis of Friction for tubo-generator Set

摩擦是一种非线性振动故障,它对机组的安全运行有严重的威胁。本文结合现场中的摩擦诊断实例依据其在时域、频域等方面所表现出的不同特征对摩擦这一振动故障进行了分类,对故障诊断有一定的意义。

The friction causes a kind of nonlinear vibration. It threatens the safe working of steam turbo - generator seriously This paper analyzes some site friction examples,classifying them according to their different features in timedomain and frequency- domain. We hope this paper is useful to vibration diagnisis.
