Способ относится к эксплуатации насосов и может быть использован для прогнозирования глубины кавитационной эрозии их деталей. Цель изобретения - повышение точности прогнозирования глубины кавитационной эрозии деталей насоса при его эксплуатации. Для этого предлагаемый способ прогнозирования глубины кавитационной эрозии деталей насоса включает измерение кавитационной эрозии за первоначальный промежуток времени работы насоса с последующим вычислением интенсивности кавитационной эрозии по известной формуле; как в первоначальный, так и в последующие промежутки времени проводят регулярные измерения давлений на входе в насос, по значениям которых вычисляют новые величины интенсивности кавитационной эрозии, а прогноз глубины кавитационной эрозии проводят по последнему значению интенсивности.The method relates to the operation of pumps and can be used to predict the depth of cavitation erosion of their parts. The purpose of the invention is to improve the accuracy of predicting the depth of cavitation erosion of pump parts during its operation. To this end, the proposed method for predicting the depth of cavitation erosion of pump parts involves measuring cavitation erosion over the initial period of time of pump operation, followed by calculating the intensity of cavitation erosion using the well-known formula; both in the initial and in the subsequent periods, regular measurements of the inlet pressure to the pump are made, according to the values of which new values of the intensity of cavitation erosion are calculated, and the forecast of the depth of cavitation erosion is carried out using the last intensity value.
