Abstract In order to provide the theories for us to design and Investigate parameters of the pump’s three dimension flow field inside impeller centrifugal pump, This text establishes the turbulent flow model according to an internal turbulent flow flowing general equations inside pump and design parameters of the IB50-32-250 centrifugal pump’s impeller, It analyses the distribution of speed and pressure of flow field inside impeller of Centrifugal Pump and proceeded a number imitation based on ANSYS8.0, It concluded out some main characteristics and distribute regulations of flow field inside impeller centrifugal pump, It has very important consults value for studying the internal fluxion circumstance of fluid machine’s impeller.
