| Abstract: | Using the self-priming fundamentals of outer recirculation,a common centrifugal pump with multistage segments is successfully reformed innovated into one with self-priming function. And its characteristics and installation sizes are kept totally unchanged. Besides , the benefits from energe saving and operation simplicity in the multistage self-priming pump is expounded in this paper. The reasons of air leakage in the seal of both end journals are analyzed, also. The elimination measures for the leakage are presented. |
