單級雙吸中開泵概述
S型泵是取代Sh型單級雙吸、臥式中開離心泵,供輸送清水及物理化學性質(zhì)類似于水的液體(液體高溫度不超過80℃)。適合工廠、礦山、城市、電站的給排水,農(nóng)田排澇灌溉和各種水利工程。SM、SF、SY型泵均是在S型泵基礎上通過改變材質(zhì)、密封、結構等措施而形成的分別適應于輸送多泥砂水質(zhì)或有耐磨要求、耐腐蝕要求或油類等介質(zhì)。
單級雙吸中開泵型號意義
150S78A
150—泵進口直徑為150mm
S—臥式單級雙吸清水泵
SM—單級雙吸耐磨泵
SF—單級雙吸耐腐蝕泵
SY—單級雙吸油泵
78—設計點揚程為78m
A—葉輪外徑切割代號,Ⅰ表示葉輪外徑增大
6Sh—6A
6—泵進口直徑為6吋(150mm)
Sh—臥式單級雙吸清水泵
6—泵比轉(zhuǎn)速的1/10取整
A—葉輪外徑切割代號
單級雙吸中開泵性能范圍
流量:160~18000m3/s
揚程:12~125m
單級雙吸中開泵結構特點
1、S、SM、SF、SY型泵的吸入口與吐出口均在水泵軸心線下方,與軸線垂直呈水平方向,泵殼中開,檢修時無需拆卸進水、排出管路及電動機(或其他動機)。從驅(qū)動端向泵的方向看,水泵均為順時針方向旋轉(zhuǎn),根據(jù)需要也可生產(chǎn)為逆時針方向旋轉(zhuǎn),訂貨時應特殊提出。
2、S、SM、SF、SY型泵的主要零件有:泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。
3、葉輪經(jīng)過靜平衡校驗,用軸套和兩側的軸套螺母固定,其軸向位置可以通過軸套螺母進行調(diào)整。葉輪的軸向力利用其葉片的對稱布置達到平衡,殘余軸向力則由軸端的軸承承受。
4、泵軸由兩個單列向心球軸承或四個向心推力球軸承支承,軸承裝在泵體兩端的軸承體內(nèi),用黃油或稀油潤滑。
5、水泵通過彈性套柱銷聯(lián)軸器由電動機直接驅(qū)動。
6、軸封為軟填料密封,為了冷卻潤滑密封腔和防止空氣進入泵內(nèi),在填料之間裝有填料環(huán),水泵工作時少量高壓水通過泵蓋中開面上的梯形凹槽或外部的不封管部件流入填料腔,起水封作用。

單級雙吸中開泵結構圖
1、本型泵的吸入口與吐出口均在水泵軸心線下方,水平方向與軸線成垂直位置、泵殼.中開,檢修時無需拆卸進水,排出管路及電動機(或其他原動機)從聯(lián)軸器向泵的方向看去,水泵均為逆吋針方向旋轉(zhuǎn)。如根據(jù)用戶特殊訂貨需要也可改為順吋針旋轉(zhuǎn)。
2、本型泵的主要另件有:泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。除軸的材料為優(yōu)質(zhì)碳素鋼外,其馀多為鑄鐵制成。
3、泵體與泵蓋構成葉輪的工作室,在進出水法蘭上制有安裝真空表和壓力表的管螺孔,進出水法蘭的下部制有放水的管螺孔。
4、葉輪經(jīng)過靜平衡校驗,用軸套和兩側的軸套螺母固定,其軸向位置可以通過軸套螺母進行調(diào)整,葉輪的軸向力利用其葉片的對稱布置達到平衡,可能還有一些剩馀軸向力則同軸端的軸承承受。
5、泵軸由兩個單列向心球軸承支承,軸承裝在泵體兩端的軸承體內(nèi),用黃油潤滑,雙吸密封環(huán)用以減少水泵壓水室的水漏回吸水室。
6、水泵通過聯(lián)軸器由電動機直接傳動。
7、軸封為軟填料密封,為了冷卻潤滑密封腔和防止空氣漏入泵內(nèi),在填料之間有水封環(huán),水泵工作時小量高壓水通過水封管流入填料腔起水封作用。
