In this paper, according to the basic centrifugal pump theory, the characteristic equations of diffuser and impeller are derived and the physical meaning of characteristic curve of diffuser is brought out. Influence of the geometric parameters of diffuser inlet and impeller discharge on the characteristic curves of diffuser and impeller is described in detail. According to the above characteristic equations and curves, this paper has put forth the calculating method of optimal operating condition for well pump. It is pointed out how to predict the optimal operting condition of the same impeller in different diffuser and different impeller in the same diffuser. At last, by analysis of performance test curves which are obtained after grouping different impellers and diffusers in the 100JC/K10 type deep-well pump, the method developed is justified.
