三、D、DG型單吸多級臥式離心泵型號意義
四、D、DG型單吸多級臥式離心泵結(jié)構(gòu)型式
D、DG、MD、DF系列泵為臥式安裝,吸入口水平(DG型進(jìn)出口都垂直向上),排出口垂直向上。泵的吸入段、中段、吐出段用拉緊螺栓聯(lián)結(jié)成一體。泵由吸入段、中段、吐出段、葉輪、軸、導(dǎo)葉、導(dǎo)葉套和平衡盤等主要零部件組成。轉(zhuǎn)子的軸向力由平衡盤平衡,軸承采用滾動軸承,用黃油潤滑。軸封采用填料密封,在填料腔中通入有一定壓力的水起水封作用。從驅(qū)動端方向看,泵為順時針方向旋轉(zhuǎn)。
五、D、DG型單吸多級臥式離心泵主要用途
D型供輸送清水或物理化學(xué)性質(zhì)類似于清水的其它液體之用。介質(zhì)溫度不大于80℃,適用于礦山排水和工廠、城市建筑供水,遠(yuǎn)距離輸水等場合。
DG型供輸送清水或物理化學(xué)性質(zhì)類似于清水的其它液體之用。介質(zhì)溫度不大于105℃,適用于小型鍋爐給水或輸送熱水和類似熱水的介質(zhì)。
MD型是在D型基礎(chǔ)上改進(jìn)設(shè)計的一種耐磨多級離心泵。MD型泵高效節(jié)能,耐磨性好,壽命長,特別適用于礦山排水,抽送固體顆粒含量不大于1.5%(顆粒直徑小于0.5mm)的礦井水及其它類似液體,液體溫度不大于80℃。
DF型單吸多級耐腐蝕泵供輸送溫度-20∽105℃,不含固體顆粒,有腐蝕性的液體。泵的進(jìn)口允許壓力為0.6MPa,主要用于化工、石油、冶金、輕工、印染、制藥、環(huán)保、海水淡化、海上采油及礦山等工業(yè)部門。
