Abstract
The paper considers the issues of the appearance of cavitation in hydroabrasive flows, which can lead to rather complex phenomena, which presents difficulties for understanding the essence of the process. Until now, the wear of the working bodies of blade hydraulic machines, depending on the mode of their operation, has not been sufficiently studied, and the method for selecting the operating modes of hydroelectric power plants (HPP) and pumping stations (PS) has not been developed, taking into account the cavitation-hydroabrasive wear of their parts. Also, the work presents the results of field and laboratory studies to study the intensity of wear of the elements of the flow path of blade hydraulic machines, taking into account the effect on the hydraulic resistance of the suction line of hydropower plants.
