Abstract:A light and small flow-ejecting self-priming spray pump which can prime faster with high efficiency is introduced.The new self-priming pump is designed with the self-priming equipment which can accelerate the mixture of air.The design method can enlarge the diameter of the vane by 4%~6%,the width of outlet by 10% and the Ⅷ section of volute by 4 times.The test result indicates that compared with the traditional self-priming pump,the performance curve of the new one is stable and smooth,the range of high efficiency is wide and the pump operates under the optimum condition.All the technical indexes of the pump are satisfied.The efficiency of the new type has been raised by 10.5%~11.1%,the self-priming time shortened by 37~48 s and the weight reduced by an average of 20%
