4、1。2.1定定子部分分主要由吸吸入段（进进水段）、中中段、吐吐出段（出出水段）、导导叶、填填料函体体（尾盖盖）和轴轴承体等等分别用用拉紧螺螺栓联接接成一体体，从联联轴器端端看，泵泵吸入口口为水平平右方向向，吐出出口为垂垂直向上上。2.2转转子部分分主要由轴轴、叶轮轮、平衡衡盘、轴轴承及轴轴套等组组成。2.3泵泵的密封封2.3.1泵吸吸入段（进进水段）、中中段、吐吐出段（出出水段）之之间的静静止结合合面用纸纸垫或二二硫化钼钼来密封封。2.3.2泵各各级间采采用节流流密封。2.3.3泵的的两侧轴轴封采用用软填料料密封。2.3.4采用用挡水圈圈挡水，防防止水进进入轴承承。2.4轴轴承部分分除MD66
5、-255、MD112-225型泵泵轴承采采用GGB/TT2922-944角接接触球轴轴承以外外，其余余泵型的的整个转转子由两两端的圆圆柱滚子子轴承GB/T283-94支承；轴承采用3号通用锂基润滑脂润滑。由于MD6-25、MD12-25型泵轴承采用了GB/T292-94角接触球轴承，所以转子无轴向窜动量，其余泵型的转子应有轴向窜动量。2.5平平衡部分分由于叶轮轮前后盖盖板受压压面积不不等，产产生轴向向力，此此轴向力力由平衡衡装置承承担。泵泵的平衡衡装置由由平衡盘盘、平衡衡套、平平衡环组组成。泵泵的平衡衡室由吐吐出段（出出水段）、填填料函体体（尾盖盖）、平平衡水管管部件所所组成，平平衡水管管部件
