摘要:Recently, cavitation surge was one of cavitation instabilities in high performance turbopumps and it damaged to a hydraulic system. In the present research, the experiments were carried out in order to investigate the influences of the branch-type and slit-type accumulators installed at a discharge pipe on cavitation surge. The experiments were conducted by the closed-type water tunnels. As a result, the occurrence region of cavitation surge in the V-shaped suction performance curve was reduced by the branch-type accumulator and the pressure amplitudes due to cavitation surge were decreased by the slit-type accumulator.
