So we can know the equipments information under working through the analyses of lubricants . the author heavily elucidates that how to forecast the failure of the equipment and how to look for fault source according to the lubricant " s variation . the specific failure cases have been analyzed by the diagnosing method based on the lubricating oil 本论文着重阐述如何从润滑油使用中的变化预测设备故障及寻找故障原因,明确提出以润滑油作为设备故障诊断技术的主题,分析了以润滑油为主体的故障诊断方法,并就具体事例进行分析。
The technique of equipment fault diagnosis is very important to avoid accident in producing , avert economy losing , establish and perfect the maintenance plan . so large numbers of scientific researchers are attracted to research on the crossed discipline of equipment fault diagnosis , so as to keep it on being developed and perfected . the technique of distributed remote fault diagnosis expert is part and parcel of the new crossed discipline 设备故障诊断技术对于生产实践中防止事故发生、避免经济损失、制定与完善维修计划等具有重要意义,从而吸引了大量科研人员从事这方面的研究工作,使得这一新兴的交叉学科不断发展与完善,分布式远程故障诊断专家技术就是新兴交叉学科的重要内容。
Main content described in this article is as follows : ( 1 ) the present status and trending of equipment fault diagnosis technology ; ( 2 ) the composition of on - line monitor and fault diagnosis system of d . c . motors , and data acquisition system in silicon rolling mill of wuhan iron & steel corporation ; relative knowledge of hardware and software configuration in systematic flowchart ; ( 3 ) what role the sensing technology plays in monitor and fault diagnosis and how to apply ; ( 4 ) through representing the development of wavelet analysis theory and knowledge , especially stressing on illustrating in feature of wavelet analysis theory and explanation of engineering , the wavelet technology , as coordinated analysis method of a signal , is gradually adopted in fault diagnosis system ; at last , it discussed the set up of expert system in the diagnosis system , and obtaining & improving relative knowledge of expert system 本论文主要内容有:首先,介绍了设备故障诊断技术的发展现状及趋势;第二,详细介绍了武钢硅钢厂直流电机在线监测与故障诊断系统、数据采集系统组成、系统工作流程等软、硬件方面的相关知识;第三,围绕本系统展开,介绍了传感器检测技术在监测与故障诊断系统中的地位及具体应用;第四、通过介绍小波分析理论的发展、小波分析理论知识,着重阐明小波分析理论的特点及工程解释,说明小波技术作为一种信号调和分析方法,正逐渐在故障诊断系统中得到应用;最后,本论文还讨论了诊断系统中专家知识系统的建立、专家知识的获取、完善专家知识系统等有关内容。
