DG锅炉给水泵使用说明书

1、DG型卧式多级锅炉给水泵产品用途：本泵标准采用JB/T6435.2-92, GB5659-85多级离心泵技术条件。DG 型卧式多级锅炉给水泵是我厂根据工业锅炉给排水有关规范开发的新产品。 由于采用 了国家推荐使用的高效节能产品的水力模型,因此 DG 型泵效率高、性能范围广、更好地满 足使用要求。用于替代老型号 GC 型离心泵,在结构上采用了卧式、多级泵分段形式,因而 运转安全、平稳、噪音低、寿命长、安装维修方便。此型泵特别适用于工业锅炉供排水、冷 却水输送等。也可以通过改变材质、密封形式和增加冷却系统用于输送热水、油品、腐蚀介 质等,广泛适用于石油化工、热水循环、环保产业、纯净水输送等行业。输

2、送介质温度为： -20 C150 C。允许进口压力为 0.6MPa。参数范围：流量： 4 750m3/h扬程：841536m （扬程由泵的级数决定并通过切割叶轮直径进行调节）产品特点：1、水力设计：采用先进的设计理论进行低比转数水力模型优化设计,叶轮流道采用特殊 的工艺手段,使其流道表面光洁,减少损失,提高效率。2、结构：在结构上采用卧式、多级分段形式,因而运转安全、平稳、噪音低、寿命长、 安装维修方便。3、泵效率高,性能范围厂,更好地满足使用要求。结构：泵壳体部分主要由轴承体、吸入段、中段、吐出段、导叶等用拉杆螺栓联接成整体。 转子部分主要由轴及安装在轴上的叶轮、轴套、平衡盘等零件组成。轴上

3、零件用平键和 轴套螺母紧固使之与轴成为一体。整个转子由两端轴承支承在泵壳体上,转子部分中叶轮个 数是根据泵的级数而定。本型泵轴承部分采用滚动轴承,部分采用滑动轴承,均不承受轴向力,泵轴向力由平衡 盘承受,泵在运行中允许转子部分在泵壳体中轴向游动。轴承采用32 号轴承油（汽轮机油）或性能类似的其它油品润滑,以获得更好的润滑性能及承受更高的温度。泵的吸入段、中段、吐出段之间密封均采用二硫化钼润滑密封,转子部分与固定部分之 间靠密封环、导叶套、填料等密封,当密封环和导叶套的磨损程度己影响泵的工作和性能时 应予及时更换。泵采用中心支撑,填料函部位设有水冷腔。轴承体内设水冷室,外表带散热片,具有很 好的

4、冷却保护,中段壳体外设有一层保护罩,以防在抽送高温介质时液体从壳体接合面之间 溅出。本型泵采用软填料密封,也可以采用机械密封。填料及机械密封的松紧程度必须适当。 从传动端看,泵为顺时针方向旋转。型号说明：例 1: DG25-50X 5DG-卧式多级锅炉给水泵25泵的流量（ m3/h）50泵的单级扬程（米）5泵的级数（叶轮个数）D G型泵材质选择表材料类别IIIIII使用温度-20 C+80 C-20 C+150 C-20 C+150 C吸入段HT200ZG230-450ZG1Cr13中段HT200ZG230-450ZG1Cr13吐出段HT200ZG230-450ZG1Cr13叶轮HT200或
