锅炉补水泵,详细锅炉补水泵参数

1、DG 型锅炉补水泵锅炉补水泵 概述：DG 型泵为单吸、多级、节段式离心清水泵。适应于矿山、工厂及城市给 排水，用来输送不含固体颗粒的清水或物理、 化学性质类似于清水的液体， 被输 送的介质温度为0C80C,允许进口压力0.6MPa。锅炉补水泵 参数范围：流量 Q 10500m3/h扬程 H 33850m锅炉补水泵 型号说明：DG 型泵在型号表示方法上有三种,现分述如下：1）DG25-30*4“ DG” 表示多级锅炉补水泵。“ 25”表示泵的流量（ m3/h ）。“30”表示泵的单级扬程（ m）。“ 4”表示级数。2）DG80-30X 5 多好呀“ DG” 表示单级、多吸、节段式离心清水泵。 “

2、80”表示泵的吸入口直径（ mm）。“30” 表示泵的单级扬程（ m）。“ 5”表示级数。 这种方法表示的泵只有 DG8030。3）150DG30 X 5“150”表示泵的吸入口直径（ mm）。“ DG” 表示单级、多吸、节段式离心清水泵。“30” 表示泵的单级扬程（ m）。“ 5”表示级数。锅炉补水泵 结构型式：DG型泵为卧式安装，所有DG型泵的吐出口方向垂直向上。轴向力由平衡 盘来平衡。轴封一般采用填料密封,根据用户需要也可采用机械密封。除 DG85-67， DG155-67 型泵采用滑动轴承、稀油润滑外，其余采用滚动轴承、油 脂润滑。锅炉补水泵的装配清洗和检查：a用没有清洗全部的零件，在

3、空气中干燥或用布擦干；b、检查全部零件的磨损情况，对不能确保正常运转的零件应更换新的；c、检查泵轴是否有灰尘或生锈，用千分表检查轴的不宜度（轴的径向跳动值 不大于 8 级精度）；DG当密圭寸间隙超过推荐值的最大值 50%寸，应更换密圭寸元件。泵的装配顺序一般是按拆卸顺序反向进行； 本型泵装配质量的好坏直接影响泵能否正常运行， 并影响泵的使用寿命和性能 参数；影响机组的振动和噪音。装配中应注意以下几点：a固定部分各零件组合后的同心度靠零件制造精度和装配质量来保证，应保护零件的加工精度和表面粗糙度、 不允许磕碰、 划伤。 作密封剂用的二硫化钼应 干净，紧固用的螺钉、螺栓应受理均匀。b、叶轮出口流道

4、与倒也进口流道的对中性是依各零件的轴向尺寸来保证。流 道对中性的好坏直接影响泵的性能，故泵的尺寸不能随意调整。c、泵装配完毕后，未装填料前，用手动转动泵转子，检查转子在壳体内旋转 是否灵活，转向窜动量是否达到规定要求。DG上述检查符合要求后，在泵两端轴封处加入填料，注意填料环在填料室中 的相置。锅炉补水泵 旋转方向： 从电机端向泵看为顺时针方向旋转。锅炉补水泵 主要零件材质： 泵的过流部件材质均为铸铁，轴的材质为 45 号钢。锅炉补水泵 成套范围： 泵于电机、底座配套供应，可配功用底座或本身底座，厂方还提供附件（包 括吐出锥管、闸阀、底阀、止回阀）和备件（包括叶轮、密封环、导叶套、平衡 盘、轴

5、套）。锅炉补水泵的拆卸 拆卸时应严格保护零件的制造精度不受损伤：拆卸穿杆的同时应将各中段用垫垫起，以免各中段止口松动下沉将轴压弯?锅炉补水泵注意亊项：a、将泵壳内的液体放掉：b、如果轴承部件是稀油润滑时应将润滑油放掉；C拆去妨碍拆卸的附属管路，如平衡管、水封水管等管路和引线，拆卸顺序：泵的拆卸步骤应从拆下吐出側的轴承部件开始， 其顺序大致如下 （因泵的结构 有所差别 . 在拆卸过程中会略有不同） :a、柠下吐出侧轴承压盖上的螺栓和吐出段、填料函体、轴承体三个件之间的 联接螺母卸下轴承部件：b、拧下轴上的圆螺母，依次卸下轴承内圈、轴承压盖和挡套后，卸下填料体 （包括填料压盖、填料环和填料等） ：

6、c、依次卸下轴上的0型密封较圈、轴套、平衡盘和键后，卸下吐出段（包括 末级导叶、 平衡环等） ;DG卸下末级叶轮和键后，卸下中段（包括导叶）：按同样方法继续卸下其余 各级的叶 轮、中段和导叶，直到卸下首级叶轮为止：e、拧下吸水段与轴承体的联接螺母和轴承压通上的螺栓后， 卸下轴承部件（在 这之前 应先将泵联轴器卸下） ；O型密封f、将轴从吸入段中抽出，拧下轴上的固定螺母，依次将轴承内圈、 圈、轴套和挡套等卸下。至此拆卸工作基本完成，但在上述拆卸过程中，还有部分零件时相互联接在一 起的，一般情况下拧下联接螺栓或螺母后可卸下。本信息由三昌水泵厂发布，水泵专业技术团队，二十余年水泵制造经验，优质服务,
