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(jì )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(yòng)工作(zuò)壓力:2.5Mpa;
介質(zhì):清水或物(wù)理(lǐ)化學(xué)性質(zhì)類似于清水的其它液體(tǐ)(固體(tǐ)顆粒≤80mg/L)。
溫度:≤105℃ 産品特點:
經設計的水力模型,不僅使泵具有水力性能(néng),并且沒有軸向力(理(lǐ)論上)這一困繞水泵特别是大型水泵運行的難題。泵體(tǐ)、泵蓋、葉輪經精(jīng)密鑄造,過流表面光滑提高了泵的抗汽蝕性能(néng)和效率。
根據輸送介質(zhì)或用(yòng)戶要求采用(yòng)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(yòng)于更換填料。 工作(zuò)條件:
1.試用(yòng)工作(zuò)壓力為(wèi)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(tǐ)和泵蓋材質(zhì)采用(yòng)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(zhì)。 
2.介質(zhì):溫度≤105℃的清水或物(wù)理(lǐ)化學(xué)性質(zhì)類似清水的其它液體(tǐ)(固體(tǐ)顆粒≤80mg/L)。 結構特點:
結構緊湊、穩定性好。該型泵為(wèi)泵殼中開結構,進出口均在泵體(tǐ)上,檢修時隻需吊出泵蓋,轉子部件便可(kě)移出進行檢修作(zuò)業,而不需拆卸管路,十分(fēn)方便。
根據需要電(diàn)動機(驅動機)可(kě)以在左端也可(kě)在右端,方便現場安(ān)裝(zhuāng)。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(kě)靠。設有泵體(tǐ)密封環,而葉輪密封環為(wèi)可(kě)選用(yòng)件。密封環磨損後可(kě)以更換,減少了運行維護費用(yòng)。
1.采用(yòng)油脂潤滑的封閉式滾動軸承,維護簡單,運行時間長(cháng)。2.配備恒定油位的油杯,也可(kě)用(yòng)稀油潤滑。3.選用(yòng)進口(SKF、NSK、NTN)高質(zhì)量軸承,運行平穩,噪音低,使用(yòng)壽命長(cháng)。
