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感染 发表于 2025-4-1 01:11:06
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
