Bearing equipment diagnosis technology

Equipment diagnosis technology is developed on the basis of equipment management and maintenance. Equipment diagnosis technology is the control of equipment state and the relationship between the abnormal or fault, now to predict the future of technology. Content it contains two aspects: one is to run the equipment monitoring, 2 it is after the discovery of abnormal situation of equipment fault analysis and diagnosis. Equipment diagnosis technology first appeared in Europe, mainly equipment integrated diagnostics is proposed in the UK as a guide, in the last century 60 - In the 70 s, the British association of machinery health and condition monitoring technology of fault diagnosis, first after the United States is the development of study with the guidance of equipment maintenance services, the United States after the Apollo programme started in 1961, a series of accidents caused by failure. Under the advocacy of NASA in 1967, presided over by the U. S. navy lab to set up the mechanical failure prevention group, actively engaged in the development of diagnosis technology, they can in aviation, aerospace, military and nuclear etc. Pointed collar city wall is in the lead. Japan has the advantages of both Britain and America, puts forward the overall stack ( TNM) Point of view. Japan's Nippon steel since 1971 the development of diagnostic technology, in 1976 to achieve practical application. Japan iron and steel, chemical エ, electric power industries in the world's leading. Our preliminary contact development diagnosis technology since 1979, paragraph really began in 1984 to promote the enterprise diagnosis technology, and gradually formed a relatively strong fault diagnosis research team, made a lot of fruitful research results, especially since the end of last century, with the development of computer technology, completely changed the face of fault diagnosis system software and hardware, all kinds of data collection, analysis, diagnosis function of the instrument were developed successively, all kinds of expert system were also now, provides engineers with a more effective means to analyze and solve the problem. But the problem also appeared, on-site engineering and technical personnel due to the limitation of professional knowledge, by the analysis of the function, interface, curve, learning I don't know why; Expert system due to the influence of sample size, reliability, accuracy has also been questioned. This makes floating in the research of fault diagnosis technology, did not go deep into the grassroots effectively, go deep into the production of the first line. Should speak so disabled diagnosis technology is a practical application of science, the research content should be in line with 'from practice to practice' principle, to solve the problems existing in the production line.
