【Abstract】 The rotary shaft pump aerator is a kind of aerator for the seedling production. It has high efficiency and has no harm to the seedlings. The paper analysed theoretically the fluid dynamic performances of the spread cap. It also analysed the factors which influence the amount of air pumped into water and the power consumed. Two series and four types of spread cap were selected to make comparative experiments. The experimental results approximately matched the theoretical prediction. From the theoretical analysis and the experiments, the best technical specifications of the spread cap were selected.更多还原
