产品概述
  GDD型低噪音管道式离心泵属于立式单级单吸清水离心泵,主要用来输送稀释清洁无腐蚀性的清水及物理化学性质类水的液体。该泵采用专门设计制造的低速低噪音电机驱动,电机和叶轮转动部件作了平衡试验,特别适用于对噪音要求比较高的场合。广泛用于农业给排水、自来水加压、高层建筑消防以及生活供水系统、高层大厦空调冷暖系统的循环供水。GDD型泵是管道式安装的立式单级(单吸或双吸)清水离心泵,由于采用了低转速电机,大幅度降低了运行噪音及振动,延长了轴承及其易损件的使用寿命。本型泵效率高,己获得中国节能产品称号。
 
相关配件及服务
  长期底价提供广一牌GDD管道泵及相关配件(机械密封、水封、电机、泵体等)。
 
具体用途
  广泛应用於工农业给排水、自来水加压、高层建筑生活供水以及中央空调、暖气循环系统中冷冻水及暖水的输送。
 
输送介质
  主要供吸送清洁的、无腐蚀的清水及物理化学性质类似水不含固体颗粒或纤维的液体。
 
性能范围
流量:3.5-1440m3/h
扬程:4.6-71m
功率:0.55-132Kw
转速:1480r/min
最高工作温度:80°C
最大工作压力:1.6MPa
  其他说明:使用温度高于105°C时,需要在订货时特别说明以便于更换耐高温的机械密封。若抽取液体中含有杂质,则可以更换耐磨机械密封。
 
泵说明
采用专门设计制造的低转速低噪声电动机驱动,电机和叶轮等转动部件作了平衡试验,特别适用於对环境噪音要求高的场合。该型泵功率在30kW以下的泵的叶轮直接安装在电机加长轴上,37kW以上的泵采用夹式联抽器与电机连接。拆开泵盖和叶轮时不需拆卸吸进和排出管路即可更换密封和叶轮。
出水口处于同一轴线上,而且口径相同,可以象阀门一样安装在管路上,安装方便简单。
旋转方向
  从电机往泵方向看,水泵为顺时针方向旋转。
 
配置
电动机配用特别设计的Y型加长轴立式低速低噪声电机,装夹式联轴器为标准Y型电机,在尺寸上和功率等级上符合IEC和DIN42673标准,运行平稳、安装方便。
电机参数
防护等级:IP44
绝缘等级:E
标准电压:380V
  ▲客户如对电机有特殊要求,在订货时提出。
