The invention relates to a centrifugal pump structural design with an inducer with long and short vanes. The vanes of the inducer comprise long vanes and short vanes which are arranged alternately. The inducer with the long and short vanes is arranged in front of an inlet of an impeller of the centrifugal pump. By the inducer with the structure, the flow condition of an inlet of a main impeller can be improved, and anti-cavitation performance of the inducer can be improved. The centrifugal pump structure with the inducer with the long and short vanes can effectively improve the anti-cavitation performance of a pump effectively.
