The experimental research on the on-line vibration monitoring tor the vertical axial tlow pump units with bi-di- rectional passages is made in Jiangsu Province. Through installing the vibration sensors on the key components of pump, and using the advanced data acquisition and analysis software, the main rotating parts of pump unit could be found out, especially the natural frequency' s vibration values and varying laws of the underwater parts under different working condi- tions. In the daily operation and management of pump, according to the changing condition of characteristic frequency' s vibration value, the fault location could be pinpointed accurately, and the fault size could be determined, at last to adopt timely and effective measures to solve problems.
