通过实验证明用加大后密封环直径并配以适当平衡孔直径的方法,可使单级单吸离心泵轴向力从原来基础上进一步减小到趋近零.这对进一步完善离心泵轴向力理论及寻求后密封环、平衡孔直径的最佳设计值具有重要意义.
The experimental results show that the axial force of the single-stage single-suction centrifugal pump can be further reduced to nearly zero from the original by increasing the diameter of the seal ring and matching the diameter of the balance hole, which is of great value to the further improvement of the centrifugal pump shaft To force theory and seek the best after the seal ring, the balance hole diameter design value is of great significance.
