■D、DG型卧式多级离心泵结构说明:
D、DG型卧式多级离心泵进、出水口均为垂直向上,通过拉紧螺栓将泵的进水段、中段、出水段、轴承体等泵壳体部分联结成一体。根据泵的扬程选择泵的级数。
D、DG型卧式多级离心泵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,其中叶轮的数量根据泵的级数而定。轴上零件用平键和轴螺母紧固使之与轴联为一体。整个转子由两端滚动轴承或滑动轴承支承。轴承按型号不同而定,均不承受轴向力,其轴向力由平衡盘平衡。泵在运行中允许转子在泵壳中轴向游动,不能采用向心球轴承。滚动轴承用油脂润滑,滑动轴承用稀油润滑,并用油环进行自润滑,循环水冷却。
D、DG型卧式多级离心泵的进水段、中段、出水段之间的密封面均采用二硫化钼润滑脂密封,转子部分与固定部分之间装有密封环、导叶套等进行密封,当密封环和导叶套的磨损程度已影响泵的工作性能时应予更换。
轴的密封形式有机械密封和填料密封两种。泵采用填料密封时,填料环的位置安放要正确,填料的松紧程度必须适当,以液体能一滴一滴渗出为宜。泵各种密封元件装在密封箱内,箱内要通入一定压力的水,起水封、水冷或水润滑作用。在轴封处装有可更换的轴套,以保护泵轴。
D、DG型卧式多级离心泵一般采用滚动轴承、干油润滑结构,DG85-67、DG155-67型泵可采用滑动轴承、稀油润滑结构,也可采用滚动轴承、干油润滑结构。泵的主要零件材料一般采用优质铸铁,也可采用铸钢或不锈钢。
D、DG型卧式多级离心泵通过弹性联轴器由原动机直接驱动,从原动机方向看,泵为顺时针方向旋转。
■D、DG型卧式多级离心泵产品用途:
D、DG型卧式多级离心泵适用于工业和城市给排水、高层建筑增压供水,园林喷灌、消防增压、远距离送水、采暖、浴室等冷暖水循环增压及设备配套等,尤其适用于小型锅炉给水。

■D、DG型卧式多级离心泵使用说明:
一、启动
泵起动前应转动泵转子,检查转子是否灵活;
检查电机转向是否与泵转向一致;
打开泵吸入阀,关闭泵出口管路闸阀及压力表旋塞,使泵内充满液体,或用真空系统排除吸入管和泵内空气;
检查泵和电机联接螺栓的松紧程度和泵周围的安全情况,使泵处于准备起动状态;
起动电机,待泵运转正常后,打开压力表旋塞,慢慢开启泵出口闸阀,直到压力表指针指到所需压力为止(按出口压力表读数控制泵给定的扬程)。
二、运行
该泵靠泵内平衡机构平衡轴向力,平衡装置内有平衡液体流出,平衡液体由平衡水管接至进水段,或在平衡室外设计一短管,平衡液体经短管流向泵外。为保证泵正常运行,平衡水管不允许堵塞;
在开车和运行过程中,必须注意观察仪表读数,轴承发热、填料漏水和发热及泵的振动和声音等是否正常,如发现异常情况,应及时处理;
轴承温升变化反映了泵的装配质量,轴承温升不得高于环境温度35℃,轴承的温度不得高于75℃;
泵转子在运行中存在一定的轴向窜动,轴向窜动应在允许范围内,应保证电机和水泵两联轴器端面间的间隙值;
泵在运行期间应定期检查叶轮、密封环、导叶套、轴套、平衡盘等零件的磨损情况,磨损过大时应及时更换。
三、停机
停机前应先关闭压力表旋塞,慢慢关闭出口闸阀,待出口阀关闭完毕后再停电机,泵停稳后再关闭泵的吸入阀;泵内水放出,如长期停用,应将泵拆卸清洗上油,包装保管。
