Acoustical characterization of external gear pumps: comparison of spur and helical gears
, 2023 The evaluation of the noise performance of hydraulic pumps is a key aspect for manufacturers as the pump often represents one of the main noise sources in hydraulic systems on end users applications. Although sound power tests are the most accurate measurement method for the acoustical characterization of a source, study relies on a more practical and ...
