Turbine units often experience failures, mainly due to prolonged operation of the turbines, which causes wear and tear on their critical components, thereby having a significant negative impact on the proper operation of the units. Research has shown that vibration is a major cause of wear in turbines. There are many factors that can lead to vibration in turbines, such as the parameters of the incoming steam, steam traps, as well as the temperature and quality of the oil used; all these factors have a significant impact on the vibration of the turbine unit. It can be seen that as long as any device or medium is related to the unit, it could be a cause of abnormal vibration in the unit. Analysis and Handling of Turbine Vibration Faults 1. Turbine Excitation and Fault Resolution Unbalanced airflow forces can cause excitation phenomena in the turbine blades ； For large units with a long final stage, the cause of steam flow excitation may be the disruption of the gas flow path at the tip of the blade. Therefore, low-frequency components with larger amplitudes, increased vibration caused by loads, and the like have a significant impact, becoming clear indicators of flow-induced excitation. In light of these two characteristics, data from long-term records of vibration for each unit are analyzed to plot the relevant curves; by observing the patterns in these curves, conclusions are drawn in written form to facilitate future work. A series of experiments have shown that, in order to avoid vapor flow excitation, it is possible to reduce the rate of load variation. 2. Characteristics and causes of abnormal vibration in the unit resulting from thermal deformation of the rotor, as well as countermeasures. 2. There are many other causes of turbine vibration, such as thermal deformation of the rotor. The occurrence of this situation depends to a large extent on the rotor temperature and steam parameters. Most of the thermal deformation of the rotor occurs during the loaded phase, that is, after the unit has started up and reached its operating speed; what increases is the amplitude of the first-order harmonic vibration. At this point, as the temperature of the rotor increases, the internal stresses in the material are released, causing the rotor to undergo thermal deformation. At the same time, as the phase of the first-order vibration increases, it also changes, which causes the rotor to bend and deform, thereby leading to abnormal vibration of the rotor.
