在参考文献[1]基础上,本文阐述将平衡孔位置外移至叶轮叶片进水边境内后,单级单吸离心泵轴向力变化规律获得改善的实验事实。分析引起这种改变的原因。得出了这种改变对泵的△γ-α数对最佳值必然产生有利影响的结论。
Based on the reference [1], this paper expounds the experimental fact that the variation of the axial force of the single-stage single-suction centrifugal pump is improved after the position of the balance hole is shifted out to the inflow boundary of the impeller blade. Analyze the reasons for this change. It is concluded that this change has a positive effect on the optimal value of the pump △ γ-α.
