为解决BWY-220/9型泥浆泵十字头摩擦副耐磨性差的问题，通过有限元软件，分析了不同材质和间隙尺寸对BWY-220/9型泥浆泵十字头摩擦副磨损的影响，并根据分析结果对十字头摩擦副进行了材质与间隙尺寸优化设计，试制加工了新的十字头摩擦副。室内型式试验表明：新十字头摩擦副磨损较小，油液未见明显污浊现象，有效地减少了摩擦热的产生，泥浆泵的整体性能得到了提升，有限元分析结果的有效性和可靠性也得到了验证。利用作者提出的方法对泥浆泵十字头摩擦副的优选具有一定的指导意义。

In order to solve the crosshead friction pair problem of poor wear resistance in Model BWY-220/9 mud pump, this paper analyzed the affluence of different materials and gap sizes to friction loss of crosshead friction pair by using finite element software. According to the analysis results, this paper proposed an optimization design for crosshead friction pair and manufactured a new friction pair. The experiment shows that the new crosshead friction pair has less friction loss and the no apparent oil contaminated. Furthermore, the friction heat is reduced and the overall property of Model BWY-220/9 mud pump is promoted. Therefore, the affectivity and reliability of finite element analysis is also verified. The method proposed in this paper can be applied to optimization design for crosshead friction pair of other mud pumps.
