基于角域的往复压缩机连杆小头瓦故障诊断

Fault Diagnosis of the Small End Bushing of Connecting Rod of Reciprocating Compressor Based on Angular Domain

针对往复压缩机在线故障诊断时难以提取连杆小头瓦故障特征的实际情况,提出了一种基于角域分析原理的在线诊断方法,简述了往复压缩机连杆小头瓦无反向角和敲击故障诊断的分析方法,并通过诊断案例证明了角域分析的实用性。

Aiming at the actual situation of difficult to extract fault characteristics of the small end bushing of connecting rod when diagnosing the fault of reciprocating compressor online, a kind of online diagnosing method based on angular domain analysis principle is pointed out.The analysis method of the small end bushing of connecting rod without reverse angle and percussion fault diagnosis is simply specified.The practicality of angular domain is proved based on the diagnosis example.
