8. First,the time series data from the vibration signals of a centrifugal pump is subject to an empirical mode decomposition(EMD) followed by a Hilbert-Huang Transformation to obtain the energy of various intrinsic mode functions(IMF). Moreover,with "energy ratio" serving as an element,the eigenvector obtained from vibration signals of the centrifugal pump by utilizing the energy ratio can depict very well fault information for different vibrations.
