Influence of cavitation-hydro abrasive wear and wear of vane hydraulic machines on the hydraulic resistance of the suction line of pumping units

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