摘　　要：针对具有典型结构的BRW200/31.5型乳化液泵在工作过程中经常出现的容积效率低、噪声高等问题,基于某公司的成熟产品,通过对泵进行理论分析计算,得出泵运行时柱塞的位移、速度曲线图。运用Fluent数值模拟仿真软件,对泵的液力端即泵头组件的流道进行流场仿真分析,找到影响上述问题的关键点,进而优化其结构,为今后的设计生产提供一定的参考。Aiming at the problems of low volumetric efficiency and high noise for the BRW200 /31. 5 emulsion pump with a typical structure often appeared in the course of work,we obtain the displacement of plunger and the velocity curve when the pump is running through the theoretical analysis for the mature product of a company. The fluid field of head assembly for pump is simulated by the numerical simulation software Fluent. And we find out the key point that impacts on the above problems,and optimize its structure. It provides a reference for the future design and production.
