| 摘 要： | 为了优化贯流泵机组支撑结构，提高其综合性能，将贯流泵机组支撑划分为主轴系轴承座支撑、灯泡体支撑和泵体支撑3个层次．研究了3种典型贯流泵机组的支撑形式；通过受力分析，计算了主轴变形和疲劳强度安全系数；从泵机组可靠性、安装维修性、总体结构和泵装置水力性能等方面，比较了几种支撑形式．从主轴轴承数量、布置及安装、灯泡体支撑和泵体支撑等方面，提出了灯泡贯流泵机组支撑的设计原则和方法．结果表明：灯泡贯流泵机组支撑形式不但影响可靠稳定性能和安装维修性能，还严重影响系统水力性能．电机转子和水泵叶轮挠度分别为0．19～0．39mm和0．22～0．62mm，滑动轴承和滚动轴承油膜厚度分别为0．41～0．53mm和0．12～0．17mm：为了保证运行时电机空气间隙和水泵叶片间隙均匀，导轴承座安装高程应考虑转子和叶轮的挠度以及导轴承的油膜厚度．合理布置导轴承，灯泡体采用辐射板支撑，进人孔与灯泡体底部主支撑合用，采用金属管泵段式结构，可以提高灯泡贯流泵机组的可靠性能和水力性能．结果对灯泡贯流泵机组的优化设计具有参考价值．

| Abstract: | In order to optimize supporting structures of bulb tubular pump units and improve the properties,the supports of bulb tubular pump units were divided into 3 hierarchies,i.e.the bearing block support,the bulb support and the pump body support.The support forms of 3 typical bulb tubular pump units were investigated.The shaft deformations and fatigue strength safety factors were calculated through force analysis.Several typical support forms were compared in pump unit reliability,installation,maintainability a... |
