11、MD(P)型卧式多级离心泵输送的介质温度不高于80。1.2泵型号意义说明MD(P)280-65×6 100MD(P)45×8MD(P)卧式多级离心泵 100吸入口直径为100mm280设计点流量（m3/h） MD(P)卧式多级离心泵65设计点单级扬程（m） 45设计点单级扬程（m）6泵的级数 8泵的级数1.3性能范围（按设计点）流量：6.3720 m3/h扬程：501140m1.4产品执行标准：MT/T114-2005煤矿用多级离心泵，Q/CSB1-2007多级清水离心泵。警告a）本系列泵的配套电机：YB系列电机可用于井下，但不能用于采掘工作面，用于采掘工作面必须配用YBK
12、系列电机，Y系列电机不能用于井下，电机必须要可靠接地！b）泵不允许在无液体介质状态下点动或运转！c）泵组的转动部分在运行时不准触摸！1.5警告2、结构特征分段式多级离心泵为两端支承，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1。2.1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，泵吸入口为水平右方向，吐出口为垂直向上。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
13、）之间的静止结合面用纸垫或二硫化钼来密封。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采用挡水圈挡水，防止水进入轴承。2.4轴承部分除MD(P)6-25、MD(P)12-25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MD(P)6-25、MD(P)12-25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积不等，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
14、、平衡套、平衡环组成。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。3、技术特性性能曲线及性能表性能表型 号级数流量Q扬程H(m)转速n(r/min)效率(%)功率(kw)必需汽蚀余量(NPSH)r(m)叶轮直径(mm)质量(kg)(m3/h)(L/s)轴功率Pa电机功率MD(P)6-2533.756.37.51.041.752.0876.57573.5295027.842.038.82.813.063.875.52.02.02.0138864102100983.754.085.167.5965127.512
