- W2363629304 abstract "In view of observed pumps vibration signals with noises,the multi- scale mathematical morphology spectrum and spectrum entropy are used to analyze the signals with different revolving speeds. The features of signals are extracted to recognize the vibration types,and then the feasibility and accuracy of the method are proved. The results show that with the gradually- increased speed,vibration features of the pump units with misalignment and coupling unbalance fault can be divided into three types,namely normal operation,periodic rubbing and chaotic operation. When the vibration type is same,the analysis results based on morphological spectrum and spectrum entropy are almost the same for any revolving speeds change. The observed signals with plenty of noise can be analyzed and handled effectively by the two methods,however the recognition success rate of morphological spectrum is higher,which contributes to vibration recognition." @default.
