介绍国内、外１０种常用的多级离心泵轴向力计算公式，分别用这些公式计算了日本产ＴＰ－４１１３－Ｐ５－１．２型泵的轴向力。通过轴向力在线监测装置对此泵的轴向力进行了在线监测，将计算结果与实测结果进行了比较，确定了比较准确的轴向力计算公式，从而为多级离心泵的设计提供了一定的理论依据。
The formulas for calculating the axial force of 10 commonly used multistage centrifugal pumps at home and abroad are introduced. The axial forces of TP-4113-P5-1.2 pump made in Japan are calculated by these formulas respectively. The axial force of the pump was monitored online by the on-line monitoring device of axial force. The calculation results were compared with the measured results to determine the more accurate axial force calculation formula, which provided the design of multistage centrifugal pump A certain theoretical basis.
