Pressure Pulsation in a Centrifugal Pump-Piping System : Experimental Examination of Characteristics of Pressure Pulsation

• GOTO Masanori

抄録

In piping systems including centrifugal pumps, a pressure pulsation is generated. In this report, a centrifugal pump is assumed to have two characteristics: the generation of pulsation and the propagation of waves. The latter is described by a transfer matrix. The values of these characteristics are obtained through experimentation, and the above assumption is confirmed. A better understanding of the role of the pump in pressure pulsation is achieved. The pulsation source of a centrifugal pump is the pulsating pump head. The experiments make it clear that the strength of the pulsation souce is independent of piping systems, and that its amplitude and phase are both almost constant at constant revolutions of the impeller. The pressure distributions in a pump-piping system may be explained clearly based on the propagation and generation phenomena of pressure waves in a simple pipe system instead of in a pump.
