Analysis and Handling Practice for theVibration Fault of TRT Generator Set in Blast Furnace
The vibration fault of TRT generator set in blast furnace is analyzed from several aspects when generator set is started up. Outage maintenance of TRT with load drop
TRT
generator rotor
booting up after overhaul
vibration of loading set are the aspects analyzed. Practice indicates that low speed balance could significantly lower the vibration of TRT generator rotor within the supercritical speed range. The low-frequency vibration fault after the overhaul could be solved by fixing the contact angle of bearing. Dynamic balance analysis on site could keep the vibration of generator rotor within a good range.Thermal dynamic balance could help solve the vibration increase caused by components expansion and deformation.
