| Abstract: | The mechanism and diagnosis method of mass unbalanced fault are investigated and special cases are analyzed in this paper.A bearing vibration fault of 600 MW supercritical unit is monitored and analyzed.The fault reason is the increasing of mass unbalance.According to the fault diagnosis results,dynamic balancing is carried out,and high-medium pressure rotor is returned to the manufactory.The case will be as a reference for the similar vibration faults process of the same type super-critical units. |
