采用数学方法，对美国水力学会标准（AHIS）中给出的粘性泵性能换算图进行了反复计算，提出了输送粘性介质离心泵性能换算公式。计算结果与图线换算法的数值完全一致，可以替代图线法，为计算机编程和研究，创造了条件。
Mathematical methods were used to calculate the viscous pump performance conversion chart given by the American Society of Hydraulic Engineers (AHIS) repeatedly, and the performance conversion formula of viscous medium centrifugal pump was proposed. The calculation result is completely consistent with the figure of the line conversion method, which can replace the graph line method and create the conditions for computer programming and research.
