Zinc ash pump is an important element to extract slags in the process of hot dip galvanizing in the steel enterprise currently. Using the principle of similarity to analyze the working process of the zinc ash pump in theory could simulate the actual producing process. Given the influence of relative parameters on zinc ash pump performance,the experimental device for water simulation could be constructed by using the dimensional analysis.Transparent PVC materials were used to establish a physical model of the experimental device for the water simulation of zinc ash pump. Through the analysis based on the principle of similarity,the experimental device conformed to the zinc ash pump in the working principle and the working process theoretically. Thus it could replace the zinc ash pump unit to complete the experiment of adjusting parameters and could also satisfy experimental requirements.
