The Study For The Equipment Vibration Monitor And Fault Diagnose System Used In Cold Rolling Line

With the dramatic development and innovation in Bao steel, the monitor and diagnose need to be accurancy, convenience and high efficiency, to meet the target of the equipments' operation, thus fulfill the maximization for the economic benefit as well as the optimize for the social benefit.The equipment maintainance staff is hard to monitor and master the operate situation whatever necessary because of the lines are situated at closed state during the operation, however, on the other hand, the process under the normal and stable circumstance is acting as an important role for fulfilling the operation target. Secondlly, the equipment is in full production all the time for the continuity, it is easy to failure. At the same time, the manual supervisory with the character of inefficiency and difficult to monitor, and also with insecure facts for itself. Under this situation, we submit the guidelines and information system about the vibration monitor and fault diagnose system according to the development of the equipment vibration monitor and fault diagnose system indoor and outdoor, integrating the study for the main operation line in Cold Rolling Mill-mill process in steel roll line, analyzing the viabration principle for the rotate equipment, the method about the signal collection and treating, the developing for the kernel program EMONITOR Odyssey. The online viabration monitor and fault diagnose system for the cold rolling line is brought into effect at last.We achieved the following success by using the equipment viabration monitor and fault diagnose system,(1) Judging the equipment fault accurately,(2) Avoiding the outburst fault,(3) Extending the operational life span of the equipment.
