Description
Summary:[...]it is crucial to have a better understanding of radiation noise frequency characteristics, to provide theoretical guidance for research on radiation noise prediction and control technology at different frequencies of centrifugal pumps. According to the above literature review, previous experimental research has mainly focused on the internal flow noise characteristics in centrifugal pump pipes, while little experimental research has focused on radiation noise outside the pumps. In general, pumps work in various conditions with various working demands and the radiation noise at different frequencies changes accordingly, so it is also necessary to study various operational conditions for radiation noise. [...]a centrifugal pump radiation noise measurement system was established in a soundproof room. According to the similarity law, the relationship between rotational speed and flow rate is defined as, Q1Q2=n1n2 where Q and n represent the flow rate and rotational speed, while the subscript 1 and 2 represent two different operation conditions.
