SOW蜗壳式单级双吸离心泵

SOW蜗壳式单级双吸离心泵SOW系列单级双吸泵的运行数据:

  • 出口直径:DN=80~500mm

  • 流量:50~4200 m3/h(额定点)扬程:H=7.6~160m(额定点)

  • 许用工作压力:2.5MPa

  • 许用试验压力:3.75MPa

  • 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≤80mg/L)

  • 温度:≤105°C

  • 水力:经优化设计三水力模型,不仅使泵具有优异的水力性能,并且没有轴向力(理论上)这一困扰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,过流表面光滑提高了泵的抗汽蚀性能和效率。

  • 密封: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。

SOW蜗壳式单级双吸离心泵SOW蜗壳式单级双吸离心泵的工作条件:

  • 许用工作压力为2.5MPa;即泵入口压力+泵扬程≤2.5MPa。根据泵壳承受的大压力,泵体和泵盖材质采用灰口铸铁(1.6MPa)、球墨铸铁(2.0MPa)、铸钢(2.5MPa)。在订货时敬请注明泵的承压情况或材质。

  • 介质:温度≤105°C的清水或物理化学性质类似清水的其它液体(固体颗粒≤80mg/L)。轴承:

  • 采用油脂润滑的封闭式滚动轴承,维护简单,运行时间长

  • 配备恒定油位的油杯,也可用稀油润滑

  • 选用进口(SKF、NSK、NTN)高质量轴承,运行平稳,噪音低,使用寿命长。

SOW蜗壳式单级双吸离心泵SOW蜗壳式单级双吸离心泵的结构:

结构紧凑、稳定性好。SOW蜗壳式单级双吸离心泵为泵壳中开结构,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。
