一肩菲、單級雙吸水平中開式離心泵概述:
S翠坟、Sh系列泵單級、雙吸犹佣、泵殼水平中開式離心泵雷倦,供輸送溫度不超過80℃的清水及物理化學性質類似于水的液體之用。改變葉輪熟排、密封環(huán)和軸套的材料,可以汲送含有泥沙的渾水虱而。泵的軸封一般采用軟填料筏餐。如有特殊定貨要求,也可裝機械密封牡拇。
二魁瞪、單級雙吸離心泵型號意義如:
三、單級雙吸水平中開式離心泵結構說明:
1惠呼、本系列泵的吸入與吐出管均在水泵軸心線的下方导俘,呈水平方向,與軸線呈垂直位置剔蹋。泵蓋用螺栓與定位銷固定在泵體上旅薄,無需拆卸管路及原動機就可檢修泵的轉子部件
2、泵的主要零件有泵體泣崩、泵蓋少梁、葉輪、軸矫付、雙吸密封環(huán)凯沪、軸套、軸承等洞歼。
a卫削、泵體與泵管為鑄鐵制成,共同構成葉輪的工作室宣验,泵體進赌矩、出水法蘭盤上有安裝壓力計和真空計的管螺孔,管徑zui低處有放水的管螺孔。
b彭倡、葉輪為雙側進水看群。其形狀是對稱的,出廠時經(jīng)靜平衡試驗赴笨。
c涯锅、軸承:本系列泵的結構分甲、乙兩種形式忆键,甲式的采用滾動軸承漱南,用黃油潤滑;乙式采用滑動軸承憋庙;用稀油潤滑笔喉。靠近聯(lián)軸器一端的通稱軸承甲部件硝皂,另一端稱軸承億部件常挚,由于葉輪是對稱的,其本身平衡了軸方力稽物,由于制造誤差等產(chǎn)生的殘余軸向力由軸承乙部件中的單例向心軸承平衡奄毡。
甲式結構的軸承體部件是籍軸承體壓蓋固定在泵體上,由于該壓蓋是裝配后與泵體同時 孔贝或,不具備互換性吼过,所以壓蓋損壞后不能更換。
d咪奖、軸封:泵的軸封由填料室盗忱、填料壓蓋、填料環(huán)羊赵、填料趟佃、軸套共同構成。泵管內的少量高壓水通過水封管及填料環(huán)流入填料室中昧捷。有些泵沒有外裝水封管揖闸,在泵蓋的中開向上有予先鑄出的兩條溝槽,代替了外裝水封管徽榄。
填料的松緊程度阐赖,以液體能一滴一滴滲出為準。填料壓得過緊胰薪,軸套易發(fā)熱皆舅,軸套表面很快就被磨損。
