4、端支承，壳体部分为节段式，泵的传动方式是通过柱销弹性联轴器与电机联结，泵的旋转方向，从驱动端看，泵为顺时针方向旋转。泵的结构见图lo2.1定子部分主要由吸入段（进水段）、中段、吐出段（出水段）、导叶、填料函体（尾盖）和轴承体等分别用拉紧螺栓联接成一体，从联轴器端看，泵吸入II为水平右方向，吐出丨1为垂直向上。2.2转子部分主要由轴、叶轮、平衡盘、轴承及轴套等组成。2.3泵的密封2.3.1泵吸入段（进水段）、中段、吐出段（出水段）之间的静止结合面用纸垫或二硫化钳来密封。2.3.2泵各级间采用节流密封。2.3.3泵的两侧轴封采用软填料密封。2.3.4采用挡水圈扌当水，防止水进入轴承。2.4轴承部分

5、除MD6-25、MD12-25型泵轴承采用GB/T292-94角接触球轴承以外，其余泵型的整个转子由两端的圆柱滚子轴承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平衡部分由于叶轮前后盖板受压面枳不等，产生轴向力，此轴向力由平衡装置承担。泵的平衡装置由平衡盘、平衡套、平衡坏组成。泵的平衡室由吐出段（出水段）、填料函体（尾盖）、平衡水管部件所组成,平衡水管部件绝对不允许堵塞，可用闸阀调节平衡水管部件内水的流动。-i0IT78910111213141
