Annotation:
The methodology of using functions with a finite carrier as basic functions when analyzing vibration parameters of gas pumping assemblies units is considered. In accordance with the table of operating frequency bands, the selection of the sampling frequency of the measuring stand is shown on the example of the turbogroup of the gas pumping assembly. The properties of the wavelet transform are compared with the properties of the window Fourier transform. Special attention is paid to the important property of signal decompositions by functions with a finite carrier, which consists in the possibility of increasing the resolution in frequency and time. The real prospects for using wavelet analysis to study the influence of operating modes of gas pumping assemblies on their reliability and the implementation of a predicative approach in the framework of modeling vibration processes that assess the probability of stopping the unit or an emergency situation already on a real-time scale are evaluated.
