20.500.12556/DKUM-53221 Analiza obratovalnega hrupa in vibracij okrova radialne črpalke Radial pump operating noise and casing-vibration analyses V prispevku je podana teoretična in eksperimentalna študija dinamičnih tekočinskih vibracij in hrupa. Eksperimentalne meritve so izvedene na enostopenjski radialni črpalki, ki obratuje s čisto hladno vodo. Pri različnih obratovalnih režimih (vrtalnih frekvencah rotorja) so izvedene meritve naslednnjih obratovalnih karakteristik: dušilna krivulja, pretok - izkoristek, pretok - obratovalni hrup in pretok - amplituda vibracij okrova. Rezultati meritev so podani v časovnem in frekvenčnem prostoru. This paper surveys theoretical and experimantal studies of fluid mechanic vibration and noise. The experimental measurements were carried out in a radial one-stage pump which operates with clean cold water. Several experimental measurements were carried out on a radial one-stage pump which operates with clean cold water. Several experimental measurements on the operating characteristics such as capacity-head, capacity-efficiency, capacity-operating noise and capacity-pump casing vibration amplitudes under different operating regimes (different impeller speed) were performed. Measurement results are given in time and frequency domains. radial pumps pump noise vibration measurements noise minimization true true false Association of Mechanical Engineers and Technicians of Slovenia et al.
