Embodiment
[0063] Embodiment: The following is an example of the on-site dynamic balance of a steam turbine generator set in a power plant provided by the inventor using this method to illustrate the applicability and effectiveness of this method to the actual shaft system with multiple flexible rotors and multiple supports.
[0064] 1) Schematic diagram of unit structure and schematic diagram of sensor installation
[0065] see figure 1 The schematic diagram of the generator set (330MW) shown in the figure shows a schematic diagram of the unit structure and a schematic diagram of sensor installation, where (a) is a schematic diagram of the unit structure, and (b) is the A-direction view of (a).
[0066] 2) Unit balancing process and vibration data
[0067] This dynamic balance is passed in figure 1 The three counterweight planes shown are weighted to dynamically balance the high and medium pressure rotors. The balancing process is listed in Table 1:
