Abstract
By using the CFX technology in ANSYS Workbench, based on the different operation conditions, the numerical simulation of three dimension steady turbulent flow is carried on the D type mine drainage pump. The pump includes first impeller and guide vane, secondary impeller and guide vane, inlet, outlet. The results will reveals the distribution law of flow field and static pressure, and it further forecasts the performance curve of the multistage pump by means of choosing standard model and setting frozen interface. This method can provide certain theory basis for the energy saving work of the multistage pump.
