Detection of cavitation phenomenon in a centrifugal pump using audible sound
TL;DR: In this article, the authors have shown that there is a discrete frequency tone within the audible noise spectra, at 147 Hz or BPF/2, which is strongly dependent on the cavitation process and its development.
Journal ArticleDOI
Noise as an indicator of cavitation in a centrifugal pump
TL;DR: In this paper, the authors used a noise spectra structure to detect the beginning of cavitation and its development and determined the required net positive suction head (NPSH) required to prevent cavitation.
Journal ArticleDOI
Improving centrifugal pump efficiency by impeller trimming
TL;DR: A method to improve efficiency of centrifugal pump by trimming the impeller, which is not strictly similar to the initial pump because only a few parameters are modified, while all the others remain unchanged.
Journal ArticleDOI
Investigation of effect of pump rotational speed on performance and detection of cavitation within a centrifugal pump using vibration analysis
TL;DR: This work investigated the cavitation phenomenon within centrifugal pumps using vibration technique and the results obtained for vibration signal in both time and frequency domains were analysed in order to gain a better understanding about the detection of cavitation in the pumps in question.
