摘要
提出一种基于十字头销载荷分析的往复压缩机故障诊断方法。通过反向角和载荷曲线判断十字头销和铜套的润滑状态及气缸压力的异常与否。详细分析了单作用往复式气压机十字头销的受力情况,给出气缸内压力测取通道的设计方法及曲轴转角的测取方法。最后通过诊断实例验证了此方法的有效性。
This paper puts forward a fault diagnosis method for reciprocating compressor based on force analysis of the crosshead pin.The abnormity of gas stress in the cylinder and the lubrication of crosshead pin and bushing are estimated through the reverse angle and force curve.Detailed force analysis is carried out for crosshead pin of a single reciprocating compressor, and the selection of the diameter of testing pressure channel and the method for measurement of crank angle are presented.Finally,the fault diagnosis method is proved highly effective through an example.
