| Abstract: | Based on the characteristic curves of the imp eller and diffuser coupling of a submersible pump, their mutual effect on each o ther is analyzed. It is shown that, only when the diffuser coupling and impeller match with each other, a higher efficiency could be obtained for the submersibl e pump. The experimental results demonstrate that, provided the ratio of throat areas of diffuser coupling to the outlet areas of the impeller is maintained con stant, a modified pump with higher efficiency could be obtained. |
