【摘要】 对于矿山企业来说，大型液压机械设备是企业生产的支柱。大型液压设备安全、高效的使用则是矿山企业安全生产的关键。因此在矿山企业大型设备的维护、保养、维修中引入现代机械设备状态监测诊断技术就必不可少。本文结合贵州开磷集团的实际情况，在其生产主力TORO400E型铲运机上进行铁谱技术应用研究，取得了成功。 本文在传统油液铁谱监测诊断技术的基础上，针对开磷集团TORO400E型铲运机的工作特点和常见多发故障特征，综合分析磨损失效机理，参考现有国内外研究成果，提出了TORO400E型铲运机状态监测诊断的基本框架，在现有铁谱技术基础上，建立了常见故障图谱库，并采用目前计算机图像处理技术可以胜任的基于图像内容的图像匹配方法，解决了铁谱技术难以推广应用的难题，使铁谱诊断技术得到了完善和提高。综合起来作了以下几个方面的工作：将先进的仪器设备结合软件形成了一套完整、高效、简便、适用的TORO400E型铲运机状态监测系统；针对TORO400E型铲运机建立完善的图谱库，开放的数据库形式可以方便的为每一台被监测铲运机建立专有的图谱库，提高的监测诊断的准确性。文中列举了开磷集团无轨设备状态监测应用实例，统计分析了系统应用以来的经济及社会效益。更多还原

【Abstract】 Large hydraulic machine service is the producing base of the mine enterprise. The right working of large hydraulic machine is the key of mine enterprise’ safe production. Therefore it is necessary for mine enterprise to monitor machine service’s state with advanced technology. In terms of the reality conditions in Kailin Co., this thesis researches on the Ferrogram application technology and has got expected results on the TORO400E hydraulic system.Based on the traditional oil Ferrogram monitoring and diagnosis technology and in allusion to TORO400E’s characteristic and its ordinary faults, combining the wear invalidation mechanism with the up-to-date theories in the world, this thesis puts forward the basic frame of the state monitoring and diagnosis of TORO400E and has established the Ferrogram database of ordinary faults. Moreover, thanks to the wonderful computer image manipulation technique, this thesis sets up the picture-matching method based on the the pictures’ viscera, and thus greatly improves the Ferrogram application technology and widely promotes its use in practice.The following works have also been done in this thesis: the combination of advanced instrument and software makes an integrated, high efficiency, convenient and applicable monitor and diagnose system for TORO400E; it has established the perfect ferrogram database for TORO400E, and the open database is easy for each monitored one to set up the special database and to improve the accuracy of monitoring and diagnosing; as an illustration, this thesis offers a practical example over TORO400E state monitoring of Kailin Group, and sums up the economic and social benefits after this system has been applied.更多还原
