Based on the layout of piping and supports and the structural features of turbine-driven pump, and combined with the onsite measuring results in power station, the analysis of vibration frequency spectrum was carried out. With the optimization in the layout and structure of turbine-driven pump inlet piping, the vibration intensity can be reduced. Also, with the methods of adding expansion joint at inlet and changing support structure and its layout, from the comparison of the vibration analysis, it was found better performance of the system can be obtained.
