摘要
为研究导流壳与叶轮相对位置对潜水泵性能的影响,以200QJ-10潜水泵为例,在保持其他参数不变的情况下,仅改变导流壳与叶轮的轴向位移来进行数值模拟。通过Fluent软件进行数值模拟计算,预测出其性能参数,从而确定出叶轮的最佳位移量。研究结果表明:随着叶轮与导流壳的轴向位移量增加,潜水泵的扬程、效率有所增加,轴功率处于周期波动状态;随着轴向位移量的继续增加,潜水泵的扬程和效率有所降低。
In order to research the influence of the relative position of the diversion shell and the impeller on the performance of the submersible pump, taking the 200QJ-10 submersible pump as an example, while keeping other parameters unchanged, only change the axial displacement of the diversion shell and the impeller to conduct numerical simulation. Numerical simulation was carried out by Fluent software to predict its performance parameters, so as to determine the optimal displacement of the impeller. The research results show that as the axial displacement of the impeller and the diversion shell increases, the head and efficiency of the submersible pump increase, and the shaft power is in a cyclical fluctuation state;as the axial displacement continues to increase, the head and efficiency of the submersible pump reduces.
