摘要
Abstract
Centrifugal pumps using in ships have an evident vibration and noise in operation. It is improved on design and man-ufacture process of a certain type centrifugal pump using in ships for the sake of controlling the noise index, considering the fac-tors which result in vibration and noise. The pump body is changed from single-shell into double-shells and the connection form of pump is changed from rigid connection into elastic connection. While the arrangement mode of the bearing is used in reason, the axial thrust of pump is supported by the pump rather than the electromotor. The pump is designed strengthening the baseboard, changed the weldments into foundry goods of the base and bracket and also improved on fabrication technology. Numerical simula-tion of interior flow in the improved pump and frequency analysis of the pump base structure are carried out and as well the vibra-tion and noise experimentation of the pump in operation. From the experimentation results it can be concluded that the improved pump satisfies the requirements of the vibration and noise indices.关键词
