6、室內(nèi)所有設(shè)備都靠它吊運(yùn)安裝.泵房上蓋已全部封閉,大部分防雨層已做完, 但是受現(xiàn)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(nèi)的天車軌道上. 由于泵房已封蓋,電機(jī)、雙吸泵只能從大門口水平移進(jìn),因為室內(nèi)天車只能到大門口4m處,雙吸水泵單重約4.3t配套電機(jī)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(nèi)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(nèi)地平標(biāo)高相等,或略高于室內(nèi),用6根鋼軌或工字鋼鋪在上面做滑道,室內(nèi)設(shè)水平底滑輪,然后利用室內(nèi)天車做動力,將設(shè)備拽入室內(nèi)天車能吊到的位置.

7、4.雙吸泵的安裝:設(shè)備運(yùn)到現(xiàn)場后,如果出廠日期在泵的防銹保證期內(nèi),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(yīng)大于0.10/1000mm,在泵加工面上測量,由于基礎(chǔ)的設(shè)計為預(yù)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(dāng)泵體精找各項指標(biāo)符合國標(biāo)后,在安裝電機(jī),此時應(yīng)檢查兩軸的同心度,通過測查聯(lián)軸器的同心度,調(diào)整電機(jī)使聯(lián)軸器的徑向位移、端面傾斜和聯(lián)軸器的端面間隙達(dá)到標(biāo)準(zhǔn)要求.立式泵安裝時,各部件的軸線均應(yīng)與泵座軸線重合,泵座法蘭面不水平偏差不應(yīng)大于0.05/1000,各法蘭連接面接觸要嚴(yán)密,無滲

8、漏現(xiàn)象,聯(lián)軸器端面之間應(yīng)無間隙,接觸應(yīng)嚴(yán)密,螺栓應(yīng)均勻擰緊.彈性柱銷聯(lián)軸器裝配允許偏差聯(lián)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(shè)備安裝 刮油刮渣機(jī)的安裝按隨機(jī)技術(shù)文件及說明書的要求進(jìn)行安裝,因設(shè)備是在軌道上運(yùn)行,軌道安裝的好壞直接影響到設(shè)備的運(yùn)行. 軌道安裝前應(yīng)對其池面上的預(yù)埋件進(jìn)行測量,記錄下各點(diǎn)預(yù)埋件標(biāo)高的高低差,所用的鋼軌要對端面直線度,扭曲進(jìn)行檢查,合格后方可使用,鋼軌鋪設(shè)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(lán)圖中的技術(shù)要求進(jìn)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(qiáng)面標(biāo)準(zhǔn)(mm)管壁厚度s20加強(qiáng)面高c1.5+12+13+1焊縫寬度e1-22-32-3管道安裝的技術(shù)要求:除藍(lán)圖要求外,均按國標(biāo)GB50235-97執(zhí)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(yīng)處于自由狀態(tài),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(zhǔn)形成十字焊縫,焊縫距離彎

10、管從起彎點(diǎn)算起不得小于100mm,管件制作或安裝時在焊口兩側(cè)應(yīng)先刷些涂料或白粉,這樣很容易清除干凈焊后的飛濺.1600環(huán)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(shè)備的無負(fù)荷試車規(guī)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(shù)量62466416四.配置施工機(jī)具1.電焊機(jī) 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(jī) 6臺5.水平儀 1臺6.經(jīng)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?zhǔn)狡鹬貦C(jī) 12臺 (2t
