4、转方向，从驱动端看，泵为顺时针方向旋转。泵的结构构见图11。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
5、挡水，防防止水进进入轴承承。2.4轴轴承部分分除MD66-255、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
6、体（尾盖盖）、平平衡水管管部件所所组成，平平衡水管管部件绝绝对不允允许堵塞塞，可用用闸阀调调节平衡衡水管部部件内水水的流动动。3、技术术特性性能曲曲线及性性能表性能表型 号号流量Q(m3/h)扬程H(m)转速n(r/mmin)效率(%)功率(kkW)必需汽蚀余量NNPSHHR(m)叶轮直径(mm)质量(kg)轴功率P电机功率MD6-2533.7556.37.5807570.442950033.0042.0043.882.4883.0663.2885.52.02.02.214386MD6-254106.810093.883.3004.0884.3777.596MD6-255133.5125117
