The invention discloses a pipe blockage overhaul prediction method for a phosphorus chemical dilute phosphoric acid supply system. The method comprises the following steps: a, constructing a phosphoric acid pump conveying capacity model containing a conveying pipeline; b, constructing a phosphoric acid pump conveying capacity regression model by utilizing the phosphoric acid pump conveying capacity model on the basis of production accumulation time; and c, adopting the phosphoric acid pump conveying capacity regression model, and predicting the next pipeline overhauling and cleaning time under a set conveying capacity threshold value through interpolation calculation. The method has the characteristics that the regular maintenance frequency is reduced, the integrating degree of the overhaul period and the actual production of the acid supply system is improved, and the equipment utilization rate is further improved. 本发明公开了一种磷化工稀磷酸供酸系统管堵检修预测方法。包括下述步骤：a.构建包含输送管道的磷酸泵输送能力模型；b.基于生产累积时间，利用所述的磷酸泵输送能力模型构建磷酸泵输送能力回归模型；
