DL、DLR、立式热水多级泵用途
DL、DLR型系列泵适用于工业和城市给排水、高层建筑增压送水、消防增压供水、远距离送水以及采暖、浴室、锅炉冷暖水循环增压、空调制冷系统送水及工业设备配套等各种场合。DL型介质使用温度不超过80℃。DLR型介质使用温度不超过120℃。
DL、DLR、立式热水多级泵外形结构图说明
DL型泵由电机和泵两部分组成,电机为Y型三相导步电机,泵和电机采用联轴器连接,整体为刚性连接,使用时无需校正。泵由定子部分和转子部分组成。泵定子部分由进水段、中段、导叶、出水段、填料函体等零件组成。为防止定子磨损,定子上装有密封环、平衡套等,磨损后可用备件更换。转子下端为水润滑轴承,上部为角接触球轴承,泵的轴向力绝大部分由平衡鼓来承担,其余小部分残余轴向力由角接触球轴承来承受。进水段、中段和出水段的结合面用纸垫通过拉紧达到密封。轴封采用填料或机械密封,用户可根据需要选择。
泵旋转方向从驱动端向下看为逆时针方向转动。
DL、DLR、立式热水多级泵型号意义
DL、DLR、立式热水多级泵主要特点
1、 泵结构紧凑、体积小、外形美观,其立式结构决定安装占地面积小,其重心重合于泵脚中心,因而增强了泵的运行稳定性和使用寿命。
2、 泵吸入口和吐出口均为水平方向,简化了管路的连接。
3、 可根据需要,吸入口和吐出口可安装成同方向或900、1800、2700几个不同方向以满足不同的连接场合。
4、 泵扬程可根据需要增减水泵级数并结合切割叶轮外径予以满足,而不改变安装占地面积,这是其它泵类所不具有的。
5、 电机外加防雨罩,泵可置于户外使用,取消泵房,节省建筑费用。
DL、DLR、立式热水多级泵的安装
1、 安装前检查水泵和电机的完好情况。
2、 泵安装位置应尽可能靠近水源处。
3、 泵与底座安装有两种方式,一种是直接装在水泥基础上的刚性连接,另一种是采用JGD型减振器安装的柔性连接,具体方法见安装示意图所示。
4、 直接安装可将泵安放在基础上垫高30~40毫米(准备充填水泥浆之用),然后进行校正,并穿好地脚螺栓,充填水泥砂浆,经3~5天水泥干涸后,拧紧地脚螺栓的螺母。
5、 安装管路时,进、出水管路都应有各自的支承,不应使泵的法兰承受过大的管路重量。
6、 泵用于有吸程场合,进水管端应装有底阀,并且进出口管路不应有过多弯道,同时不得有漏水、漏气现象存在。
7、 在进口管路上最好装有过滤网,以防杂质进入叶轮内部。滤网的有效面积应是进水管面积的3~4倍,以保证液体的自由畅通。
8、 为了维护和使用方便安全,在泵的进、出口管路上各安装一只调节阀及在泵出口附近安装一只压力表,以保证泵在额定范围内运行,确保泵的正常运行和使用寿命。
9、 进口如需扩径连接,请选用偏心异径管道接头。

DL、DLR、立式热水多级泵常见故障分析及其排除方法
故障现象 | 可能产生的原因 | 解决方法 |
水泵不吸水压力表和真空表指针剧烈跳动 | 1、灌注引水不够2、管路与仪表联接处漏气3、吸程过高 | 1、检查底阀是否漏水,再灌足引水2、拧紧漏气处3、降低吸水高度 |
水泵不吸水真空表表示高度真空 | 1、底阀没有打开或已堵塞2、吸水管路阻力太大3、过滤器堵塞 | 1、检查底阀2更换吸水管3、清理过滤器 |
压力表有压力但仍不出水 | 1、出水管阻力太大2、旋转方向不对3、出口管阀门未开4、叶轮堵塞 | 1、检查或缩短水管2、检查电机,两相互调3、打开出口阀4、清除叶轮内的污物 |
达不到设计流量 | 1、有空气吸入2、由于水位降低,淹没深度不够3、叶轮内有异物堵塞4、转子部分严重磨损 | 1、检查漏气部位并排除2、延长吸水管,加深淹深度3、拆卸并清除异物4、更换密封环 |
泵消耗功率过大 | 1、填料压得过紧,并发热2、流量过大3、回转体与壳体有碰擦4、泵轴承磨损5、泵轴弯曲 | 1、适当放松2、关小闸阀开度3、修整4更换轴承5更换或校正 |
泵振动加大 | 1、叶轮局部有堵塞2、叶轮破损3、流量过小4、泵轴与电动机不同心5、轴承破损6、混入空气,发生汽蚀 | 1、拆卸清除异物2、更换3、稍开出口阀4、定点找正5、更换6、改变吸入位,改善吸水管 |
