It is known that low-cycle system oscillation occurs in piping systems which are used with cavitating high-speed pumps. Most available papers on this subject attempt to predict this occurrence through linear transfer matrices of pumps under cavitation both experimentally and theoretically. There are few papers, however, that discuss low-cycle system oscillation with the oscillation cavitation occurring in the reverse flow at the pump inlet. The following discusses three types of low-cycle system oscillation defined by synthetic studies and the effects of NPSH, pump flow rate, rotational speed and pipe length are clarified experimentally.
