介绍了一种内装式结构的矿用潜水泵的设计方法,分析了底座进水孔、泵盖高度、涡室流道及泵出水口位置对泵水力性能的影响,并优化了这些过流部件的设计;叶轮设置浮动密封环,减少了密封环的泄漏量,可提高泵的容积效率;主轴底端设置导轴承,可减少转子的径向跳动;油室内特殊设计了一种双端面机械密封,保证双端面机械密封摩擦副端面比压始终大于弹簧比压。
补充资料：机械零件:浮环密封
浮环密封
靠浮动金属圆环与轴或壳体间的极小间隙限制流体泄漏的非接触式动密封(见图 
浮环密封 )。浮环可在壳体内自由浮动﹐因此轴高速旋转和產生振动时对密封的影响较小﹐摩擦﹑磨损也很小。浮环密封是一种高速密封﹐可用以密封气体和液体。密封气体时﹐浮环装置中应充满润滑油﹐以利密封和润滑。
