This paper describes the basic characteristics of the variousexciting sources of the pumping set, and analyses and calculates the vibration frequencies of the sources. It also analyses the characteristics of the surface vibration signals and its spectrums of the different position in the pumping set. This is the preparation for the condition monitoring and fault diagnos ing of the pumping set in operating state using the surface vibration signals, which supplies a basis for the ‘predicting maintenance' to substite the‘regular intervals maintenance'.
