Abstract:

Abstract:In domestic thermal power plants, there always were problems of excessive equipment maintenance and insufficient equipment maintenance.The precision inspection system of China Huadian Corporation was introduced. In the system, five technologies, the vibration analysis, the infrared analysis,the ultrasound analysis, the oil analysis and the motor current analysis,were combined to grasp the equipment operation situation all sidedly and exactly.The application of the system in power plantsshows that large amount of equipment defects were found and eliminated by the precision inspection.The equipment emergency repair was reduced greatly, and the unit load reducing operation and unplanned shutdown incidents were avoided repeatedly.Theequipment management level of thermal power plant was raised effectively.
