摘  要：
结合冲压泵的工艺特点,针对100XQJ8-43/9型不锈钢冲压潜水井泵,进行了基于Fluent软件的数值模拟。为了提高数值模拟的精度,考虑用不同的网格数与不同级数模型,对不同叶片厚度的不锈钢冲压井泵进行了全流场数值模拟,分别从泵的外特性及内部流场分析了叶片厚度对泵整机性能的影响规律,得出:随着叶片厚度的增加,泵的最高效率点向小流量方向偏移,设计工况下的泵内部湍流损失逐渐递增。通过样机试制及试验,发现在设计工况下采用两级全流场的数值模拟值与试验值接近,误差在1%以内,验证了数值模拟计算的可行性。

摘  要：
Combined with the technological features of stamping pump,numerical simulation based on Fluent was made for 100XQJ8-43/9 stamping well pump.In order to improve the accuracy of numerical calculation,numerical calculation of stamping well pump model of different blade thicknesses was carried out by using different grid numbers and different stage models.The relationship between the blade thickness and the overall performance of pump was analyzed from the external characteristics and internal flow field.In conclusion,with the increase of blade thickness,the best efficiency point of pump shifts to the small flow direction and the internal turbulence losses of pump were increasing gradually.Through the experiment of the mode pump,the numerical simulation values under the whole flow field are much closed to the experimental values and the error is less than 1%,which verified the feasibility of numerical simulation.The text would be instructive to the optimization of new-type well pump which is designed by the impeller diameter maximum approach.
