WT5,5”BZ]This paper discusses mainly the structure of the new type of static flow mixer and its mixing mechanism of Mid Volume Vacuum Resin Dosing Equipment. Through dynamic analysis of small hole shooting flow, the distributing diagram of velocity of shooting fluid and the mathematical model of the pressure loss in mixer are derived. In this paper, the influence of flow velocity and the number of mixing units on mixing effect are also analyzed and the evaluation method of mixing effect of mixer is presented. Using this method, the results of theoretical analysis and the mixing effect of the new type of static flow mixer are proved experimentally. The results indicate that the mixing effect of the new type of static flow mixer is satisfied.
