To study influence of run?time on dynamic characteristics of water/oil separation, a mathematical model is established to describe flow field in vacuum oil purifier. Evaporation of droplet phase transition equations are established, considering effect of three?phase flow of oil/water/vapor and water droplets evaporation phase change. Influences of run?time on oil/water/vapor three?phase volume fraction distribution and axial dehydration rate are analyzed. Dynamic characteristics of oil/water/vapor three?phase flow at different run?time is indicated. Efficiency of dehydration of water/oil separation is enhanced with run?time. It provides a foundation for further research on water/oil separation mechanism in vacuum oil purifier.
