Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Vibration diagnostics of electrical submersible using the apparatus of the continuous wavelet transform V.N. EFANOV A.N. KITABOV The article presents a qualitative analysis of existing methods of vibration monitoring of electrical submersible equipment, describe their advantages and disadvantages. Unit of the continuous wavelet transform was sort out as the most promising for use in diagnosing problems. The main types of basic wavelets suitable for vibration analysis of electric submersible equipment were presented. The basic types of mechanical defects in this type of equipment were described. We propose a method for increasing the accuracy and quality of diagnostics submersible electrical equipment apparatus based on the use of continuous wavelet transform signals vibration sensors. It is shown that each of the defects has its own topology wavelet vibration signal measured on energized equipment. Based on the analysis of wavelet transforms scalegram received diagnostic features allowing to estimate the presence and severity of defects.
