三 从机械设备诊断技术的起源与发展来看,机械设备诊断技术的目的应是“保证可靠地高效地发挥机械设备应有的功能”。这里包含了三点:一是保证设备无故障,工作可靠;二是保证物尽其用,设备要发挥其最大的效益;三是保证设备如将有故障或已有故障时,能及时诊断出来,正确地加以维修,以减少维修时间、提高维修质量、节约维修费用,应使重要的设备能按设备状态进行维修(即视情维修或预知维修),改革目前按时维修的体制。应指出,设备诊断技术应为 Third, from the origin and development of mechanical equipment diagnostic techniques, the purpose of mechanical equipment diagnostic techniques should be “to ensure that the proper functions of mechanical equipment are exerted reliably and efficiently.” Here are three points: First, to ensure trouble-free equipment, reliable work; Second, make the best use of equipment, equipment to play its greatest benefits; Third, to ensure that equipment, such as there will be fault or fault, can be diagnosed in time , To be properly repaired in order to reduce maintenance time, improve the quality of maintenance and save maintenance costs, should make important equipment can be repaired according to the equipment status (that is, depending on the situation or predicted maintenance), the reform of the current maintenance system on time. It should be noted that equipment diagnostic techniques should be
