D型单吸多级分段式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*的水力模型设计而成的高效节能更新换代产品。根据输入介质、温度不同派生出DG、MD、DF系列泵。
二、D、DG型单吸多级卧式离心泵参数范围
流量Q:6.3∽450m3/h
扬程H:17.5∽670 m
三、D、DG型单吸多级卧式离心泵型号意义
四、D、DG型单吸多级卧式离心泵结构型式
D、DG、MD、DF系列泵为卧式安装,吸入口水平(DG型进出口都垂直向上),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。转子的轴向力由平衡盘平衡,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,泵为顺时针方向旋转。
五、D、DG型单吸多级卧式离心泵主要用途
D型供输送清水或物理化学性质类似于清水的其它液体之用。介质温度不大于80℃,适用于矿山排水和工厂、城市建筑供水,远距离输水等场合。
DG型供输送清水或物理化学性质类似于清水的其它液体之用。介质温度不大于105℃,适用于小型锅炉给水或输送热水和类似热水的介质。
MD型是在D型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)的矿井水及其它类似液体,液体温度不大于80℃。
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、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。
