Abstract：With the use of RNG turbulent model in the CFD software Fluent,the inner flow of double suction centrifugal pump with semi-spiral suction chamber was calculated.It was found that the flow rate is increasing from inlet to outlet in the impeller at the first half of impeller channel;the velocity beside the pressure side of blade is larger than that beside the suction side.The flow field distribution of impeller is uniform.But in the semi-spiral suction chamber,swirls occur beside the tongue and sealed block at the designed flow rate,and the swirls become more obviously when the flow rate increases,which has effect on the inlet condition of the impeller.The above analysis provides references for the improvement of the double suction pump with semi-spiral suction chamber.
