Abstract：A L9(34) orthogonal experiment was designed with four factors and three values respectively,including splitters bias angle in peripheral direction,deflection angle,its inlet diameter and blades numbers.Fused Deposition Modeling craft was adopted to make the nine impellers and three impellers with different blade numbers and without splitter blades.Performance tests were conducted.The test results show the common effects of splitter blades as follows: the curves of Q-H are more flat,the curves of Q-η move to the larger flow rate,the district with high is efficient broadened,and the curves of Q-P are steeper.By range analysis,the primary and secondary sequence of the four design parameters of splitter blades were obtained,meanwhile the test results in larger flow rate were also analyzed,which has the same primary and secondary sequence,and more schemes that can meet the design request.It shows that the pump with splitter blades can be operated in larger flow rate.
