烟道机设备诊断技术全部介绍（All diagnostic techniques of flue gas turbine equipment are introduced） Equipment diagnosis technology of flue machine The diagnosis technology of flue gas turbine equipment is developed on the basis of equipment management and maintenance. In China since 1979 was the initial contact with the development of diagnostic technology, 1984 started business promotion of vibration fault diagnosis, then the instrument is very simple, can only measure the displacement velocity and acceleration vibration, without the function of spectrum analysis, with the development of technology, the instrument will later have manual analysis of vibration frequency. The instrument is a simple one, can not automatically record the vibration spectrum, but at the time of the fault diagnosis in the field of personnel, can analyze the vibration frequency components at any time in the field, engineers have been very satisfied, this instrument is simple and practical, can solve the vibration problem of most of the. At the end of twentieth Century, with the development of computer technology, completely changed the appearance of hardware and software for vibration analysis of a variety of instruments, data acquisition, analysis and diagnosis functions have been developed, various expert systems have emerged, for engineering and technical personnel to provide a more effective means to analyze and solve problems. But the problems also arise, by professional knowledge limitation due to the field of engineering and technical personnel, face analysis, curve interface, a superb collection of beautiful things, know not why. The reliability and accuracy of the expert system are also questioned because of the influence of the number of samples. In recent years, the editor and the scene engaged in equipment management of extensive communication engineering and technical personnel, aware of the current fault diagnosis work to promote the application of the biggest obstacle is the field staff en
