/DG25-50x8型锅炉给水泵技术说明、厂家、价格一、DG25-50x8型锅炉给水泵概述：该系列泵系节段式多级离心泵，采用了国家推荐使用的高效节能水力模型，具有高效节能、性能范围广、运行平稳、低噪音、长寿命、安装维修方便等优点；通过改变泵的材质（或过流部件的材质）、密封形式和增加冷却系统，可输送热水、油类、腐蚀性和含磨料的介质等。

DG型泵供输送不含固体颗粒、温度不高于105℃的清水或物理化学性质类似于清水的液体，用于锅炉给水或输送热水或类似热水的介质。

泵的进口允许压力均不超过0.6MPa。

二、DG25-50x8型锅炉给水泵参数范围：流量：15-30m³/h扬程：144-618m三、DG25-50x8型锅炉给水泵型号说明25 -- 泵设计点流量为25m³/h50 -- 泵单级设计点扬程为50m8 -- 泵的级数为8级/四、DG25-50x8型锅炉给水泵结构说明：卧式多级离心泵主要由固定部分、转子部分、轴承和轴封四大部分组成；1、固定部分：主要由吸入段、中段、吐出段和导叶等组成，用穿杠将各段拉紧，构成工作室。

吸入口为水平方向，出口垂直向上；根据需要也可生产出入口垂直向上方向。

2、转子部分：主要由轴、叶轮、平衡盘、和轴套等组成。
