一、SF型不銹鋼雙吸中開泵結(jié)構(gòu)說明
SF型不銹鋼雙吸中開泵的吸入口與吐出口均在水泵軸心線的下方,與軸線垂直成水平方向。檢修時無需拆卸進(jìn)出口水管及電機(jī)。從傳動方向看去,離心泵為順時針方向旋轉(zhuǎn)(根據(jù)用戶需要亦可改為逆時針方向旋轉(zhuǎn))。SF型不銹鋼雙吸中開泵適用于化工、石油、冶金、電力、造紙、食品、制藥、合成纖維等行業(yè)用于輸送各種腐蝕或*的液體介質(zhì),介質(zhì)溫度為0℃~80℃,允許進(jìn)口壓力0.6MPa。
二、SF型不銹鋼雙吸中開泵結(jié)構(gòu)說明
SF型不銹鋼雙吸中開泵主要零件有:泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套等。
SF型不銹鋼雙吸中開泵泵體與泵蓋構(gòu)成葉輪的工作室。在進(jìn)出水法蘭上,制有安裝真空表和壓力表的管螺孔。水泵進(jìn)出水法蘭的下部,制有放水的管螺孔。
SF型不銹鋼雙吸中開泵經(jīng)過靜平衡校驗(yàn)的葉輪,用軸套和兩邊的軸套螺母固定在軸上,其軸向位置可通過軸套螺母進(jìn)行調(diào)整。
SF型不銹鋼雙吸中開泵泵軸由兩個單列向心球軸承支承。軸承裝在軸承體內(nèi)、安裝在泵體兩端,用黃油潤滑。
SF型不銹鋼雙吸中開泵雙吸密封環(huán)用以減少水泵壓水室的水漏回吸水室。
SF型不銹鋼雙吸中開泵通過彈性聯(lián)軸器由電動機(jī)直接傳動,必要時亦可用內(nèi)燃機(jī)傳動。
SF型不銹鋼雙吸中開泵軸封為軟填料密封(根據(jù)用戶需要可采用機(jī)械密封結(jié)構(gòu))。
三、SF型不銹鋼雙吸中開泵型號意義
例如:300S58A
300-離心泵入口直徑(mm)
SF型單級雙吸化工中開離心泵
58-設(shè)計(jì)點(diǎn)揚(yáng)程(m)
A-葉輪外徑改變標(biāo)志
