The Effect of the Operating Point on the Pressure Fluctuations at the Blade Passage Frequency in the Volute of a Centrifugal Pump

Abstract: An experimental investigation is presented which analyzes the unsteady pressure distribution existing in the volute of a conventional centrifugal pump with a nondimensional specific speed of 0.48, for flow-rates from 0% to 160% of the best-efficiency point. For that purpose, pressure signals were obtained at 36 different locations along the volute casing by means of fast-response pressure transducers. Particular attention was paid to the pressure fluctuations at the blade passage frequency, regarding both ampl… Show more

“…The shape and location of the volute tongue also significantly affecting the pump performance such as the measurement done by Lipski [19]. Parrondo-Gayo et al [20] experiment with mounting of pressure transducers on front side of volute circumferentially around impeller outlet, found that pressure fluctuations and amplitudes are to be very dependent on both angular position and flow rate, maximum values corresponded to the tongue region for off-design conditions.…”

“…Up to now, lots of numerical and experimental investigations have been carried out, and the fast Fourier transform (FFT) method has been proved to be the most powerful tool to unveil the frequency characteristics of pressure fluctuations. Yao et al [8] analysed both frequency domain and time-frequency domain in a double suction centrifugal pump based on fast Fourier transform (FFT) and time-frequency representation methods. Parrondo et al [9] also investigated the unsteady pressure distribution in a conventional centrifugal pump, and particular attention was paid on pressure fluctuations at blade passage frequency.…”
