产品详情

一、D型多级泵相关产品概述
  D型泵系单吸多级分段卧式离心泵,是在老产品DA型泵基础上大胆改进结构并采用先进的水力模型设计而成的高效节能更新换代产品,全部取代老DA型泵,根据输入介质、温度派生出DG、MD、DF系列泵。


二、卧式多级泵系列结构说明
  D、DG、MD、DF等系列泵为卧式安装,吸入口水平(DG 垂直向上),排出口垂直向上。泵的吸入段、中段、吐出段用拉紧螺栓联结成一体。泵由吸入段、中段、吐出段、叶轮、轴、导叶、导叶套和平衡盘等主要零部件组成。转子的轴向力平衡盘平衡,轴承采用滚动轴承,用黄油润滑。轴封采用填料密封。在填料腔中通入有一定压力的水起水封作用。从驱动端方向看来,为顺时针方向旋转。

三、、卧式多级泵主要用途

   1. D型泵供输送清水或物理及化学性质类似于清水的其它液体之用。介质温度不大于80℃,它适用于矿山排水和工厂、城市建筑供水,远距离输水等场合。

     2. DG型供输送清水或物理及化学性质类似于清水的其它液体之用。介质温度不大于200℃,适用于小型锅炉给水或输送热水和类似热水的介质。

     3. MD型单吸多级耐磨泵是在D型泵基础上改进设计的一种耐磨多级离心泵。MD型泵高效节能,耐磨性好,寿命长,特别适用于矿山排水,抽送固体颗粒含量不大于1.5%(颗粒直径小于0.5mm)的矿井水及其他类似液体,液体温度不高于80℃。

     4. DF型单吸多级耐腐蚀泵供输送温度-20~105℃不含固体颗粒,有腐蚀性的液体。泵的进口允许压力为0.6MPa,主要用于化工、石油、石油化工、冶金、轻工、印染、制药、环保、海水淡化、海上采油及矿山等工业部门。
