Monitoring of the technical condition of gas pumping units (GPU), including the average power of the GPA- Ts-16S type, is important during operation, since damage to its main unit - the blade apparatus can lead to significant economic losses and, in some cases, to an accident. The analysis of the methods of parametric and vibroacoustic control relative to the technical condition of the HPA blade apparatus showed that the methods of vibroacoustic control were most widely used. The paper discusses the possibility of using discriminant analysis of vibration arising during the operation of the GPA-Ts-16S to highlight the necessary information about the technical condition of its blade apparatus. One of the features of the discriminant vibration analysis method is a high sensitivity to incipient defects, which is especially important for a blade apparatus. At the same time, the sensitivity of the S-discriminant can be adjusted by changing the value of the flare threshold. A block diagram of the developed algorithm for vibration monitoring of the technical condition of a blade apparatus with adaptation to its original (normal) one based on the results of one-dimensional discriminant analysis of the experimental data of vibration of GPA-Ts-16C is given. Vibration records obtained using the developed methodology and technical means of measuring vibration based on the latest Siemens design, the vibration module SM1281. The results of the implementation of the algorithm of vibration monitoring of the technical condition of the blade apparatus using the records of vibration GPA-Ts-16S at the compressor station KS-3 "Dolina" of the management of main gas pipelines (UMG) "Prikarpattransgaz", which were obtained within two years and describes the technical condition of HPA Ts-16C before repair, after repair and during long-term operation.
