This paper used time series method to analyze the vibration faults of working compressor, and the time series model of vibration signal was setup in the paper. The characteristic normal residue square sum (NRSS) is used to identify the fault state. The result of experiment shows that NRSS is effective for compressor fault diagnasis.

本文运用时间序列方法研究工作状态下回转式压缩机的振动故障。对压缩机的振动信号进行建模,并提出用特征值归一化残差平方和(NRSS)作为识别故障状态的指标。实验结果证明:NRSS指标对回转式压缩机故障诊断是十分有效的。

In this paper, the need for expert systems (ES) for diagnosis and mainte-nance are discussed , as well as the conditions that justify the application ot expert sys-tems. Several examples of expert systems for diagnosis and maintenance are given, alsoa (partial) list of expert systems for diagnosis and maintenance that have been developedthroughout the world. The relative advantages and disadvantages of human expert andexpert systems are discussed , and also the present state and future direction of develop-ment of expert systems for diagnosis and maintenance.

专家系统就是把专家的知识技能和经验输入电子计算机,按照编制的特定程序软件,通过电子计算机处理,给用户和咨询者提供关于该问题的合理咨询和决策。同时,按用户和咨询者的需求,该系统还具有检测、推理和直接提供信息资料的功能。由于雇员的离职和退休,工厂企业需要他们的知识、技能和经验。专家系统可以帮助把这些专门知识储存起来,应用于故障诊断和维修领域。于是TexasA&M大学林学系农业实验站,1989年开发出车床专家系统(LES)。在日本,1990年又开发出汽车空调压缩机故障摄影专家系统。表1部分地列出了全世界主要的有关故障诊断和维修的专家系统。专家系统和专家是有根本区别的。专家系统是模拟人的思维过程的计算机程序,它不能包括普通数学、物理和化学等知识,也不包括某一特殊设备的故障诊断和维修,它缺乏专家的推理和想象能力。表2对专家系统和维修工程师的特点进行了比较。未来的诊断故障和维修专家系统应能同工作过程实时操作,还应扩大监测、诊断和维修的功能,并图示化。图3就是其流程图。

This paper analyses the mechanisms of the C501 compressor faults in a chem-ical works,diagnoses,the cause of the faults according to the data recorded,and puts forwardthe measures to deal with the faults, The checking result is identical with that of the diagno-sis. It is proved that the fatilt diagnostic technique is scientific、accurate and reliable.

本文对某化工厂C501压缩机故障进行了详细的机理分析,根据数据处理技术诊断出了故障原因,提出了处理故障的具体措施。停车后解体检查结果与诊断结论完全吻台,从而证明了故障诊断技术的科学性、准确性、可靠性。
