Pump systems (PC) can often operate under conditions of non-stationarity, under which cavitation and self-oscillation appear, the efficiency and service life of the equipment decrease. The complexity of determining the presence of non-stationary processes and the automated diagnostics of PC in these conditions is due to the lack of clear informative parameters by which the presence of this process can be uniquely classified. In the article, an analysis of this problem was made using the example of real industrial PC, methods for diagnosing and controlling the operating modes of PC were examined, and the dependence of non-stationary processes on the performance characteristics of PC was determined.
