SOW series volute centrifugal pump
SOW series single-stage double-suction center-open volute centrifugal pumps are mainly used to transport clear water or liquids with physical and chemical properties similar to water at a temperature not higher than 105°C. Applicable to water supply plants, pumping stations, power stations, air-conditioning circulating water, heating hot water circulation, industrial water supply systems, fire fighting systems, ships, oil refining industries (general liquids) and other occasions where liquids are transported.

技術參數:
出口直徑:DN=80~500mm
流量:50~4200m3/h(額定點)
揚程:H=7.6~160m(額定點)
試用工作壓力:2.5Mpa;
介質:清水或物理化學性質類似于清水的其它液體(固體顆粒≤80mg/L)。
溫度:≤105℃ 產品特點:
經設計的水力模型,不僅使泵具有水力性能,并且沒有軸向力(理論上)這一困繞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。
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。 工作條件:
1.試用工作壓力為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。 
2.介質:溫度≤105℃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)。 結構特點:
結構緊湊、穩定性好。該型泵為泵殼中開結構,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,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,運行更穩定可靠。設有泵體密封環,而葉輪密封環為可選用件。密封環磨損后可以更換,減少了運行維護費用。
1.采用油脂潤滑的封閉式滾動軸承,維護簡單,運行時間長。2.配備恒定油位的油杯,也可用稀油潤滑。3.選用進口(SKF、NSK、NTN)高質量軸承,運行平穩,噪音低,使用壽命長。
