Development Of Rotating Machinery Condition Monitoring And Fault Diagnosis System

Along with the modern industrial production equipment developing towards large scale, continuous, high speed and automatization, more and more people pay attention to the breakdown diagnosis technology of mechanical device. Keeping continuity of the production and reducing the down time of equipment, especially the important equipment, is the base of the high economic efficiency that the enterprise pursues. And the condition monitor of the equipment and the breakdown diagnosis technology provides an effective key to the situation for this.The topic is proposes according to requirement of Panzhihua New Steel Vanadium Co in the situation of equipment management and safety of Heating furnace combustion air blower. For insuring the Combustion furnace blower system not to break down, reducing the manual interference, and increasing the automation and the auto-adapted ability, proposed uses the computer real-time monitor and the automatic diagnosis. In order to make the product have certain versatility, the hesis studies at all kinds of rotating machine to make the product adapt to all kinds of rotating machine or Major part rotating machine.On the basis of studying a lot of relation information and the work other people had done before, the thesis has developed the rotating machine's computer real-time condition monitored and failure diagnosis system, according to the rotating machine's characteristics. The thesis has studied the composing of monitored and diagnosis system by computer, the signal collection of the failure diagnosis technology, the methods of signal analysis, particularized the whole process of the signal collection and the signal analysis, include the process of the hardware choice and software Application. The development system merges signal gathering, the signal processing, the signal analysis, the breakdown diagnosis and the tendency forecasts into one organic whole, has certain versatility in the revolving machinery. The man-machine contact surface is friendly, the operation is simple, the function is perfect, the automaticity is high, and it has the good feasibility and the usability, has certain specialization and the commercialization level. This set of system has been normal use already in the Panzhihua New Steel Vanadium Co, and obtains the very good effect.
