SOW蝸殼式單級雙吸離心泵

SOW蝸殼式單級雙吸離心泵SOW系列單級雙吸泵的運行數據:

  • 出口直徑:DN=80~500mm

  • 流量:50~4200 m3/h(額定點)揚程:H=7.6~160m(額定點)

  • 許用工作壓力:2.5MPa

  • 許用試驗壓力:3.75MPa

  • 介質:清水或物理化學性質類似于清水的其它液體(固體顆?!?0mg/L)

  • 溫度:≤105°C

  • 水力:經優(yōu)化設計三水力模型,不僅使泵具有優(yōu)異的水力性能,并且沒有軸向力(理論上)這一困擾水泵特別是大型水泵運行的難題。泵體、泵蓋、葉輪經精密鑄造,過流表面光滑提高了泵的抗汽蝕性能和效率。

  • 密封:根據輸送介質或用戶要求采用填料密封或機械密封,不受轉向限制。對于填料密封,有足夠的空間用于更換填料。

SOW蝸殼式單級雙吸離心泵SOW蝸殼式單級雙吸離心泵的工作條件:

  • 許用工作壓力為2.5MPa;即泵入口壓力+泵揚程≤2.5MPa。根據泵殼承受的大壓力,泵體和泵蓋材質采用灰口鑄鐵(1.6MPa)、球墨鑄鐵(2.0MPa)、鑄鋼(2.5MPa)。在訂貨時敬請注明泵的承壓情況或材質。

  • 介質:溫度≤105°C的清水或物理化學性質類似清水的其它液體(固體顆粒≤80mg/L)。軸承:

  • 采用油脂潤滑的封閉式滾動軸承,維護簡單,運行時間長

  • 配備恒定油位的油杯,也可用稀油潤滑

  • 選用進口(SKF、NSK、NTN)高質量軸承,運行平穩(wěn),噪音低,使用壽命長。

SOW蝸殼式單級雙吸離心泵SOW蝸殼式單級雙吸離心泵的結構:

結構緊湊、穩(wěn)定性好。SOW蝸殼式單級雙吸離心泵為泵殼中開結構,進出口均在泵體上,檢修時只需吊出泵蓋,轉子部件便可移出進行檢修作業(yè),而不需拆卸管路,十分方便。
根據需要電動機(驅動機)可以在左端也可在右端,方便現場安裝。結構上縮短轉子部件軸向尺寸,軸的鋼性更好,運行更穩(wěn)定可靠。設有泵體密封環(huán),而葉輪密封環(huán)為可選用件。密封環(huán)磨損后可以更換,減少了運行維護費用。
