| beschreibung | The pressure pulsation is one of the main causes of vibration and noise in axial flow pump, in order to study the mechanism of pressure fluctuation induced by vortex, several pressure pulsation monitoring points were stalled at the bottom of the pump sump, the horn mouth, the impeller inlet and outlet, the outlet of the guide vane. The flow rate of 1.2Qd ( Q=38.4L/s) was selected at the speed of 2200r/min. Realizable k- epsilon turbulence model is adopted with setting up different time calculation methods by using CFX software. Changing the time step, unsteady calculation of axial flow pump device is carried out, and the pressure values of different monitoring points at different time are obtained. The frequency domain characteristics of different feature sections are obtained by FFT. The results show that the vortex position at the bottom of the inlet of the flare tube is consistent with the position of the low pressure zone, and the main frequency of the pressure fluctuation i... |
