一、單級雙吸水平中開式離心泵概述:
S、Sh系列泵單級、雙吸、泵殼水平中開式離心泵,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、密封環(huán)和軸套的材料,可以汲送含有泥沙的渾水。泵的軸封一般采用軟填料。如有特殊定貨要求,也可裝機械密封。
二、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、本系列泵的吸入與吐出管均在水泵軸心線的下方,呈水平方向,與軸線呈垂直位置。泵蓋用螺栓與定位銷固定在泵體上,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、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。
a、泵體與泵管為鑄鐵制成,共同構成葉輪的工作室,泵體進、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、葉輪為雙側進水。其形狀是對稱的,出廠時經靜平衡試驗。
c、軸承:本系列泵的結構分甲、乙兩種形式,甲式的采用滾動軸承,用黃油潤滑;乙式采用滑動軸承;用稀油潤滑。靠近聯(lián)軸器一端的通稱軸承甲部件,另一端稱軸承億部件,由于葉輪是對稱的,其本身平衡了軸方力,由于制造誤差等產生的殘余軸向力由軸承乙部件中的單例向心軸承平衡。
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,不具備互換性,所以壓蓋損壞后不能更換。
d、軸封:泵的軸封由填料室、填料壓蓋、填料環(huán)、填料、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。有些泵沒有外裝水封管,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。
填料的松緊程度,以液體能一滴一滴滲出為準。填料壓得過緊,軸套易發(fā)熱,軸套表面很快就被磨損。
