锅炉给水泵40DG 40X6

概述D型泵是采用JB/T6435.2及GB5659-85《多级离心泵技术条件》、MT/T114-2005《煤矿用多级离心泵》制造的卧式分段式多级离心泵，它适合于输送清水（杂质含量小于1％，固体颗粒小于0.1毫米）及物理化学性质类似于清水的其它液体。

也可通过改变材质、密封型式和增加冷却系统而适用于输送热水、油品、腐蚀性介质等。

D型泵输送的介质温度不大于800C，适用于高层建筑或大型建筑的生活（增压）供水、排水和消防以及空调机组的冷却水循环等。

DG(锅炉给水泵)：输送的介质温度不大于105℃，适合于输送热水的场合。

如锅炉给水、城市和企业的供暖系统。

根据输送的介质不同D型泵可分为：DY(多级离心油泵)：输送不含固体颗粒、温度为-20~1050C、粘度小于120厘泊的油类和石油产品。

DF(耐腐蚀多级离心泵)：输送不含固体颗粒、温度为-20~1050C的腐蚀性液体。

MD(耐磨矿用多级离心泵)：输送颗粒含量≤１.５％，粘度≤０.５mm温度为-20~1050C的中性矿井水及其他类似的污水．参数范围：额定流量：6—740米3/小时额定杨程：40-690米（扬程的高低可通过增减泵的级数来达到）转速：2900转/分，1450转/分型号意义D（DG、DF、DY、MD） 4 6 — 5 0 × 1 0100 D（DG、DF、DY、MD）16 × 3泵的级数泵的级数泵的单级扬程（m）泵的单级扬程（m）泵的流量（m3/h）卧式多级泵卧式多级泵泵进口直径（m m）泵的轴承规格结构说明泵的结构参见结构图本系列多级泵为两端支承，泵通过弹性柱销联轴器与电机联接。

泵的旋转方向从驱动端看为顺时针旋转。

D型泵吸入口呈水平方向，出水口为垂直向上。

DG型泵的进出水口均为垂直向上。

多级泵存在着较大的轴向力（与泵的级数成正比），轴向力全部由平衡机构平衡，轴承不承受轴向力。

泵在运行时允许转子有轴向串动，故不能采用向心轴承。

轴承采用钙基黄油润滑。

水泵的主要参数有：流量，用Q表示，单位是M3/H ，L/S。

扬程，用H表示，单位是M。

对清水泵，必需汽蚀余量（M）参数非常重要，特别是用于吸上式供水设备时。

对潜水泵，额定电流参数（A）非常重要，特别是用于变频供水设备时。

电机的主要参数：电机功率（KW），转速（r/min），额定电压（V），额定电流（A）水泵型号代表水泵的构造特点工作性能和被输送介质的性质等。

由于水泵的品种繁多，规格不一，所以型号也较紊乱，这里只列出一些常见的水泵型号。

BA型泵单级单吸悬臂式离心泵，流量为4.5~360米³/时，扬程为8~98米，介质温度在80℃以下。

以8BA——18A为例：8——代表吸入管接头为8英寸；BA——代表单级单吸悬臂式离心泵；18——代表缩小1/10后化为整数的比转数；A——代表缩小了外径的叶轮。

SH型泵单级双吸泵壳水平中开的卧式离心泵，流量为102~12500米³/时，扬程为9～140米，介质温度小于80℃。

如48SH-22：48——代表吸入管接头为48英寸，即入口直径为1.2米；SH——代表单级双吸泵壳水平中开的卧式离心泵；22——代表缩小了1/10后化为整数的比转数，即ns≈220.DA型泵单吸多级分段式离心泵，流量为25～350米³/时，扬程为25～550米。

DG型高压锅炉给水泵安装使用说明书三昌泵业ISO9001质量体系认证企业长沙三昌泵业有限公司目录一．产品综述1二．用途及型号说明1三．技术参数及机构说明2四．辅助设备说明12五．泵的拆卸14六．泵的检修16七．泵的装配19八．安装说明21九．使用维护须知24十．给水泵安装、运行主要注意事项26十一．给水泵组热控保护29十二．间隙31十三．故障和原因31一、产品总述DG系列高压锅炉给水泵是我公司根据市场需要而开发的系列产品。

本产品为单壳体节段式多级离心泵，中心水平支撑，进水口和出水口方向均为垂直向上，用拉紧螺栓将进水段、中段和出水段联结成一体。

泵进水段、中段及出水段之间的静密封采用金属面密封和“O”形密封圈双道密封，泵轴封采用高性能苎麻软填料、机械密封或螺旋迷宫加填料密封，密封可靠、安全。

在进出水段外端设计有冷却腔可外接水冷却轴和轴封体，有效阻止热量向轴承方向传递。

泵通过膜片联轴器或弹性联轴器由电机驱动，也可以根据用户需要配用小汽轮机驱动，采用液力偶合器传动。

从传动方向看泵，泵为顺时针方向旋转。

本产品符合JB/T8059-1996<<高压锅炉给水泵技术条件>>。
