摘要:
为对废泵进行利用,在现有蜗壳的基础上设计新的高效低噪叶轮。结合叶轮的外径、叶片出口角、叶片包角和叶片数4个因素,按照L9(34)正交试验方案设计9个叶轮,将其与现有蜗壳配套成9台泵,采用Fluent软件对泵进行数值模拟,分析离心泵内流场和外特性,并对满足设计扬程要求的泵进行稳定性分析。结果表明:4号泵(叶轮外径为246.2 mm,叶片出口角27.35°,叶片包角110°,叶片数7)效率最高,轴功率最小并且内流场和稳定性表现都较为优秀; 因素分析表明:出口角对离心泵效率的影响最大,包角对离心泵轴功率、扬程和叶轮扭矩的影响最大。
Abstract:
To make use of waste pump, a new impeller with high efficiency and low noise was designed based on the existing volute. Four factors about impeller diameter, blade outlet angle, blade wrap angle and blade number were considered in the orthogonal experimental design. Nine impellers, fitted with the existing volute, were designed according to the scheme L9(34). The flow fields in these pumps were simulated by using Fluent software. The inner flow fields and the external performances of these centrifugal pumps were analyzed, and the stability analyses were carried out with regard to the pumps meeting the design requirement. The results showed that No.4 pump(impeller diameter 246.2 mm, blade outlet angle 27.35°, blade wrap angle 110°, and blade number 7)performed excellently on inner flow field and stability, and it had the minimum shaft power and the maximum efficiency. From the factor analysis results, it could be seen that blade outlet angle had the greatest influence on centrifugal pump efficiency and the blade wrap angle had the greatest impact on centrifugal pump shaft power, head and impeller torque.
