摘　　要：轴向力的预测和平衡是多级泵设计和优化中的重点和难点。以150QJ20型深井离心泵为例,在Fluent中采用标准k-ε湍流模型、SIMPLEC算法、二阶迎风方程,对包含叶轮、导叶在内的两级深井离心泵进行了全流场数值计算,对不同工况下的泵效率、单级扬程和单级轴向力进行了预测。随后对样机进行了外特性和轴向力的试验测量。将数值模拟结果与试验结果对比,分析了预测值与试验值的差异,结果表明利用数值模拟方法可以较为准确地预测深井离心泵的外特性和轴向力。The forecast and balance of axial force is the key and difficult aspect in the design of multistage pump.150QJ20 type deep-well centrifugal pump was chosen as an example;the whole flow field of two-stage deep-well centrifugal pump was simulated in Fluent by the standard k-ε turbulence model,SIMPLEC algorithm and second-order upwind scheme.The pump efficiency,single-stage head and single-stage axial force at different operating points were obtained by numerical simulations.The external performance and axial force of the prototype pump were tested by the experiments.The difference between numerical results and the experimental result were compared and analyzed.The results indicated that the numerical methods could accurately forecast the pump performance and axial force.
