Paper Title:
Design and Test for High Specific Speed Mixed Flow Pump with Volute
  Abstract

The characteristics and research actuality on mixed flow pumps are introduced simplely. A mixed flow pump with volute as diffusion part is designed and its specific speed is 556.8. The axial velocity circulation and blade angle variety with linearity distribution are used to deisign the impeller. The fixed diffeuser between impeller and volute is deigned by arc airfoil.The cross sections of volute are all asymmetry. The commercial code FLUENT is applied to simulate the inner flow in the mixed flow pump and its energy characteristics are predicted according to the simulation results. The inner flow analysis indicates that the flow in the pump is good and the characteristic prediction shows that the pump performance can meet the design demand. The experiment test of the pump are done. When the blade angle is about 0°, the maximum efficiency of the pump is up to 85.76% and the actual efficiency at design point is about 3% higher than demand efficiency. The study fruits can instruct the hydraulic design of higher specific speed mixed flow pump with volute as diffusion part.
