产品简介
SOW型蜗壳式双吸清水管道泵系水平中开蜗壳式双吸泵,主要供输送温度不高于105℃的清水或理化性质类似于水的液体。作为大流量泵适用于自来水厂、泵站、电站、空调循环用水、采暖用热水循环、工业供水系统、消防系统、船舶、炼油工业(一般性液体)等输送液体的场合。
运行数据
出口直径:DN=80~500 mm
流量:50~4200 m3/h(额定点)
扬程:n=7.6~160 m(额定点)
许用工作压力:2.5 MPa;许用试验压力:3.75 MPa
介质:清水或物理化学性质类似于清水的其它液体(固体颗粒≤80 mg/L)。
温度:≤105℃
水力性能
经优化设计的水力模型,不公使泵具有优异的水力性能,并且没有轴向力(理论上)这一困绕水泵特别是大型水泵运行的难题。泵体、泵盖、叶轮经精密铸造,过流表面光滑提高警惕了泵的搞汽蚀性能和效率。
密封性能
根据输送介质或用户要求采用填料密封或机械密封,不受转向限制。对于填料密封,有足够的空间用于更换填料。
工作条件
1、SOW型蜗壳式双吸清水管道泵许用工作压力为2.5 MPa;即SOW型蜗壳式双吸清水管道泵入口压力+双吸泵扬程≤2.5 MPa。根据化工泵泵壳承受的大压力,泵体和泵盖材质采用灰口铸铁(1.6 MP a)、球墨铸铁(2.0 MPa)、铸钢(2.5 MPa)。在订货时敬请注明泵的承压情况或材质。
2、介质:温度≤105℃的清水或物理化学性质类似于清水的其它液体(固体颗粒≤80 mg/L)。
轴承
1、单级双吸泵采用油脂润滑的封闭式滚动轴承,维护简单,运行时间长。
2、蜗壳式双吸泵配备恒定油位的油杯,也可用稀油润滑。
3、选用进口(SKF、NSK、NTN)高质量轴承,运行平稳,噪音低,使用寿命长。
结构说明
结构紧凑、稳定性好。SOW型蜗壳式双吸管道泵为泵壳中开结构,进出口均在泵体上,检修时只需吊出泵盖,转子部件便可移出进行检修作业,而不需拆卸管路,十分方便。
根据需要电动机(驱动机)可以在左端也可在右端,方便现场安装。结构上缩短转子部件轴向尺寸,轴的钢性更好,运行更稳定可靠。设有泵体密封环,而叶轮密封环为可选用件。密封环磨损后可以更换,减少了运行维护费用。

小知识
泵的出品是否增加锥管加大出口管路?
我们知道,电力输送与泵的水力输送有极大的相似性。在电力输送上,线路越长、电线越细(截径越小),那么线损就越大,电压隆就越大。而在水力输送上,管路越长、管径越小,则管路损失越大、压力降低越多。那么为了减小 管路损失是否就一味地增大管路呢?这就如是否加粗输电线一样是一个经济问题。增大管路,是可以降低线损,从而节约电能,甚而可以降低水泵的扬程和所配的电机,节约设备投资,然而另一方面也增加线路投资(包括管路和各类阀门等及维修费)。所以应当从客路长度和水泵运行时间上进行综合性的经济决策。一般而言,长距离输送就不必增大(或少增大)出口管路,而应采取加压或接力输送。
水泵的开机与关机操作顺序
首次开机时,有联轴器的泵可以拆下联接部分,点动电动机试验转向。或者不拆联轴器,在泵内有水时试验电动机转向。电动机与泵直联的,也必需保证泵内有时才能试验转向。严禁在泵内无水时直接开机(泵)试验电动机转向。
开机前必须保持泵内充满引水。开机时完全打工进口阀,关闭出口阀,启动电动机,待电动机以正常转速运行后缓慢打开出口阀至所需的流量或压力。注意:不能让泵在出口阀未打工和泵所规定的小流量内长时间运行。
泵运行时禁止用进口阀调节流量,必须保持进口阀大的开度。
关机时先关闭出口阀,然后关闭电动机,安装了进口阀的在电动机停转后关闭以保证泵内存有引水(有单向阀可不关闭)。在北方防冻期(或环境温度低于液体的结冰温度)必须放尽泵内存水以防冻裂水泵。长期停用,需放尽泵内的水,必要时拆解水泵,清洗零部件防锈处理,妥善保管。
