Bearing problems of the modern industrial production

Modern industrial production more and more large-scale, high speed, automation, especially in the petrochemical industry, metallurgy, electric power, equipment investment is big, of long production process, mechanical equipment downtime can be made into great economic losses, and even lead to major accidents machine apart. Modern production and some special equipment more and more dependent on people is low, more and more dependent on equipment is high, of the fault signal and clinical cure more and more important. Equipment condition monitoring and fault diagnosis as ー engineering technique, is developed in the 1960 s after. Nearly two hundred and thirty years to the research and development of the domestic equipment diagnosis technology hyperactive, development is rapid, often used in factory, unexpected effect has been made in equipment diagnosis technology enterprises should get the popularization and use in the factory. Therefore, an urgent need to provide a batch of suitable for different levels of science and technology personnel, especially enterprise first-line technical personnel practical book, at the same time also need some books of reference, suitable for use in undergraduate and postgraduate study. Professor Arthur yeung think of the 'practical mechanical equipment fault diagnosis technology is a set of should be a written demand. Of equipment condition monitoring and fault diagnosis, in fact, since the emergence of the machine has been produced. When people hear, touch, see and smell of the machine vibration, temperature, noise and other anomalies, relying on the experience of the craftsman, can determine fault and take some countermeasures or repair the machine. Equipment condition monitoring and fault diagnosis as a new engineering technology is becoming a information, monitoring, communication and integration technology such as computer and artificial intelligence, and gradually developed into a new multidisciplinary cross disciplines. I used to work in a factory for 32 years, since 1979, the application of equipment fault diagnosis technology. I appreciate the book's publication, because it already has a basic theoretical knowledge, and the engineering application technology, engineering and technical personnel of the enterprise is a rare real books with technology; For the lack of engineering practice experience of colleges and universities graduate student also is very good reference book. Equipment condition monitoring and diagnosis technology, is to run the machine as a 'live', it always in 'speak' to send a message, about the fault symptom information collection, processing, analysis, to early diagnosis, prediction, fault in the machine to find out the cause of the problem and take actions before damage repairs, prevention and improvement measures.
