Study of Vibration Fault Diagnosis on TRT

TRT unit is very important mechanical equipment in steel industry. It not only embodies in saving energy utilization of blast furnace gas, but also can stabilize a top pressure, reduce smelted fluctuation, and make the blast furnace more stable. Therefor, to implement TRT unit vibration monitoring and fault diagnosis is quite necessary. The vibration fault diagnosis of TRT is researched on this paper. Virtual instrument, modern signal detection and analysis technique, order analysis as well as the high-speed rotor dynamic balance technology are studied on TRT unit. At present, lots of enterprises use the vibration signal detection to ensure the safe running of the equipment and promptly eliminate the hidden danger. It has a great effect on research of TRT fault diagnosis system and security of the safe operation on TRT units.
