5、的基礎必須有明確的標高點,坐標位置的縱橫軸線,復測結果必須符合下表規范的規定.序號項 目極限偏差1基礎各不同平面的標高+0-202基礎坐標位置(縱橫軸線)203基礎上平面外形尺寸凸臺上平面外形尺寸凹穴尺寸20-20+204基礎上平面的水平度(包括地平上需要安裝設備的部分)5/100010(全長)5豎向偏差5/100010(全高)6預留孔地腳螺栓:中心位置 深度 空壁垂直10+20102.墊板的選擇經計算后墊板規格選用16090mm每根螺栓各墊兩組墊板,滿足要求.3.設備的吊裝搬運由于平流池的水泵房土建已全部施工完畢,泵房已全部封閉,設備運進室內比較困難,由其室內的10t橋式吊車必須先安裝,因為

6、室內所有設備都靠它吊運安裝.泵房上蓋已全部封閉,大部分防雨層已做完, 但是受現場實際位置所限,只能在M N跨揭開蓋板,利用30t汽車吊站在草圖所示位置,將天車吊裝到泵房內的天車軌道上. 由于泵房已封蓋,電機、雙吸泵只能從大門口水平移進,因為室內天車只能到大門口4m處,雙吸水泵單重約4.3t配套電機重約6.15t,膜片水泵控制閥重2.5t由于室外汽車吊只能送到泵房的大門口,室內的天車又決不允許外拉斜拽,只有采取臨時措施,具體辦法如圖示用型材在室外做一平臺,與室內地平標高相等,或略高于室內,用6根鋼軌或工字鋼鋪在上面做滑道,室內設水平底滑輪,然后利用室內天車做動力,將設備拽入室內天車能吊到的位置.

7、4.雙吸泵的安裝:設備運到現場后,如果出廠日期在泵的防銹保證期內,又無明顯的缺陷,泵不宜拆卸,只作表面的清洗和檢查,泵的安裝縱向、橫向水平偏差不應大于0.10/1000mm,在泵加工面上測量,由于基礎的設計為預留孔,泵需兩次安裝,初找正時,在土建澆灌地腳螺栓時要注意檢查地腳螺栓是否碰歪,以防水泥凝固后螺栓歪斜無法處理.當泵體精找各項指標符合國標后,在安裝電機,此時應檢查兩軸的同心度,通過測查聯軸器的同心度,調整電機使聯軸器的徑向位移、端面傾斜和聯軸器的端面間隙達到標準要求.立式泵安裝時,各部件的軸線均應與泵座軸線重合,泵座法蘭面不水平偏差不應大于0.05/1000,各法蘭連接面接觸要嚴密,無滲

8、漏現象,聯軸器端面之間應無間隙,接觸應嚴密,螺栓應均勻擰緊.彈性柱銷聯軸器裝配允許偏差聯軸器外形最大直徑D(mm)兩軸心徑向位移(mm)兩軸線傾斜端面間隙s(mm)90-1600.050.2/100023195-2002.54280-3200.0835360-410464800.157540686305.設備安裝 刮油刮渣機的安裝按隨機技術文件及說明書的要求進行安裝,因設備是在軌道上運行,軌道安裝的好壞直接影響到設備的運行. 軌道安裝前應對其池面上的預埋件進行測量,記錄下各點預埋件標高的高低差,所用的鋼軌要對端面直線度,扭曲進行檢查,合格后方可使用,鋼軌鋪設時,可將一根鋼軌斷為兩截,鋪在兩條鋼

9、軌的起始端,一根在軌道的南端,一根在軌道的北端,使兩軌道的接頭錯開,兩平行的鋼軌的軌距4m,兩平行軌道端面的高低差5m,縱向不水平度10m,對于其它方面的要求按藍圖中的技術要求進行.6.工藝管道安裝所有工藝管道安裝均采用V形坡口,坡口形式如下表管道焊縫加強面標準(mm)管壁厚度s20加強面高c1.5+12+13+1焊縫寬度e1-22-32-3管道安裝的技術要求:除藍圖要求外,均按國標GB50235-97執行,需要注意的是焊縫離開支架不得小于100mm,所有管道在與泵體連接時均應處于自由狀態,絕對不允許給泵附加外力,如使用卷制鋼管,對接時焊縫要相互錯開大于100mm,不準形成十字焊縫,焊縫距離彎

10、管從起彎點算起不得小于100mm,管件制作或安裝時在焊口兩側應先刷些涂料或白粉,這樣很容易清除干凈焊后的飛濺.1600環形管制作見下圖1，下料見下圖2。7.管道的試壓,吹掃方案,設備的無負荷試車規程另行編制 圖一圖二三.人員安排工種鉚工配管鉗工電焊氣焊架工電工后勤數量62466416四.配置施工機具1.電焊機 6臺 交流2.氣焊工具 6臺套3.框式水平 2個 200mm 1個 150mm 1個4.角磨機 6臺5.水平儀 1臺6.經緯儀 1臺7.電動水壓泵 1臺 1.0MPa8.彈簧秤 1個 200N9.千斤頂 3臺 (5t、10t、30t)10安全燈變壓器 1臺11.鏈式起重機 12臺 (2t
