Noise and Vibrations,w. The flow in the stator acts back on the velocity field in the impeller. The related phenomena are called “rotor/stator interaction” (RSI). As a consequence of the RSI, hydraulic excitation forces are generated. These give rise to pressure pulsations, mechanical vibrations and alternating stresses

Operation of Centrifugal Pumps,ich ensure that the pump operates in the range between the allowable minimum and maximum flow - in particular if pumps are operated in parallel. Proper procedures must be implemented for start and stop. Transient operation and unsteady phenomena which need attention include: dynamic instabilities ca
