Abstract

The purpose of this paper is to investigate the clocking effect of impellers and the superposition between pump stages caused by clocking effect in a five-stage centrifugal pump. Then the best clocking scheme in terms of vibration is tried to be provided as well.Design/methodology/approachAll curves of pressure fluctuation in different impeller stages can be divided into two groups for the difference of 1/16 T in time domain. The difference is mostly in vibration frequency and amplitude, little in pump head and efficiency.FindingsAll curves of pressure fluctuation in different impeller stages can be divided into two groups for the difference of 1/16 T in time domain.
