| Abstract: | According to the technical problems of the moving crosshead bearing temperature monitoring problems of a reciprocating compressor in petrochemical industry, combined with the characteristics of reciprocating compressor crosshead reciprocating motions, an wireless optical fiber sensing online-monitoring method for crosshead bearings of reciprocating compressors was presented. The wireless mechanism, monitoring method and the characteristics of wireless fiber sensing output were studied. The results show that the method may still monitor temperature with the 20% energy transfer efficiency, which shows the feasibity of the wireless fiber sensing online-monitoring method. |
