摘要	Based on the four main factors influencing the design of short-blade of complex impeller which contains the number of short-blade, the radial inlet position, the bias angle in peripheral direction and the deflection angle, 16 different types of complex impellers with different combinational form of short-blades have been designed. By range analysis of the orthogonal designing scheme, the sequence affecting pump head and efficiency of the four main factors were obtained, the number of short-blade, the deflection angle, the bias angle in peripheral direction, the radial inlet position and the number of short-blade, the radial inlet position, the bias angle in peripheral direction, and the deflection angle, meanwhile the best design scheme of short-blade was given. Performance tests were conducted by the CFD software. The test results show that the distribution of pressure field and velocity field of the compound impeller designed by orthogonal design are reasonable, the φQ-Hφ curve is more flat and the φQ-μφ curve shifts to the larger flow rate. In the same design conditions, the centrifugal pump with complex impeller works with good performance at larger flow rate.
