iào)整墊，一般都放置在地腳螺栓處，如果底座或設備較長，在兩地腳螺栓的中間可放置一塊墊鐵。5.1.4.2檢查底座或設備下面的地基，清洗灰塵，油和其它雜物。5.1.4.3起重吊鉤吊住底座或設備的吊耳或吊孔，把底座或設備吊在地基上方，慢慢地安放底座或設備，并對準每個地腳螺栓孔的位置。5.1.4.4用一個刀口平尺和機械水平儀放到安裝泵和電機底腳加工平面上或地基上，用調(diào)整楔鐵或調(diào)整墊的厚度來確定底座或設備在各個方位上的水平，推薦每100mm長度不平度小于0.25mm，這時地腳螺栓的螺母擰到適當?shù)某潭龋ú荒苓^緊），楔鐵或調(diào)整墊片應緊固。5.1.4.5底座或設備找平，而且和地基配合較緊后再灌漿。5.1.5底座或設備的灌漿5.1.5.1混凝土基礎至少應固化7天后，才能灌漿。5.1.5.2為了保證除去灌漿部位低強度的，疏松的混凝土，在灌漿之前，應當用一把尖錘把水泥基礎材料的頂部刨掉約10～25mm。5.1.5.3所有的潤滑脂、潤滑油、油漆、水泥面上的沫狀物和其它無用雜物都應當從需要灌漿的表面上除去。粗糙的混凝土表面應當用油壓縮空氣吹去灰塵和松散的顆粒。如果采用水泥砂漿，混凝土表面應當用水浸透，直到不再吸水為止，多余的水應該除去。5.1.5.4底座或設備應該放置在要求的位置上，把底座或設備支承在楔形調(diào)整墊上或調(diào)水平的螺釘上，并用地腳螺栓把底座或設備固定，在底座或設備邊沿的底部和刨鑿過的基礎頂部之間允許有約25～50mm的灌漿空隙。5.1.5.5在灌漿之前，地腳螺栓預留孔中的所有積水和外來雜物都應該除去。5.1.5.6如果在灌漿之后還存在空洞，可以使用環(huán)氧砂漿來充填這些空洞，如果灌漿用的是水泥砂漿，則在應用環(huán)氧砂漿補空洞之前，建議讓水泥砂漿先經(jīng)過整28天的固化。在已發(fā)現(xiàn)的空洞處通常用手壓泵來灌補環(huán)氧砂漿。應當極其小心以保證不使壓力過大以免把底座或設備頂翹曲，每個空洞至少應該鉆一個通氣小孔以防壓力過大。5.1.5.7當灌漿材料固化后，擰緊地腳螺栓的螺母，然后再對灌漿材料涂油漆防潮。5.1.5.8灌漿后，進行泵和電動機的調(diào)正工作。5.2設備的調(diào)整設備調(diào)正包括角度調(diào)正和中心線位置的調(diào)正，至少應在下面三個時期檢查設備，進行調(diào)正：第一次，泵的底座已經(jīng)擰緊，但電動機沒擰緊；第二次，泵和電動機已緊固，但吸入和吐出管路法蘭的螺栓沒緊固；第三次，在運轉24小時后，再檢查一次，檢查后把泵和電動機最后緊固。在調(diào)正工作中應注意以下事宜：a）在調(diào)正以前，檢查全部的管路，保證它們不對泵底座或設備產(chǎn)生作用力或力矩；b）在調(diào)正泵和電動機軸中心線對正時，墊片應墊在電動機的下面。角度調(diào)正是保證聯(lián)軸器的兩個平面的平行度。用一塊千分表去檢查聯(lián)軸器法蘭端上四個點，千分表讀數(shù)為0.02~0.03mm。檢查其平行度也可用塞尺，兩聯(lián)軸器平面間的差值（a－b）≤0.06mm。中心線對中是指泵和電動機軸中心線的對正程度，應使c≤0.08mm（見圖2）。5.3主要管路的聯(lián)接泵灌漿后且緊固在地基上以后，在不受外力條件下對正聯(lián)接泵法蘭和管路的法蘭，這個對正聯(lián)接不能領先法蘭螺栓的力。對管路支撐（附加）應避免管路系統(tǒng)的振動，應減少管路對泵的外加力。為了防止泵的損壞，在泵管路聯(lián)接以前要對管路系統(tǒng)進行清洗。安裝管路，應注意下列事項：a）使用管路的規(guī)格和長度應合適，且有足夠的承壓能力，盡量減少管路的轉彎和附件；b）泵的吸入管路應是短而直，管路直徑應大于或等于泵的吸入口的直徑，泵的吸入管路的彎曲半徑應盡量大。如采用錐管，則采用偏心錐管，以免沉氣而發(fā)生汽蝕。5.4輔助設備—壓力計的聯(lián)接在吸入管路和吐出管路上用的壓力計必須是質量好，性能合格的儀表。吸入壓力計一般裝配在與泵入口同心同直徑的管路上，正當情況下是裝配在泵進口法蘭2倍入口管徑處，并在入口直管段中心線的水平位置。吐出壓力計最好裝配在泵吐出法蘭2倍的泵出口管徑處，并垂直于蝸殼平面或泵殼所形成的彎管平面的位置上。不能裝在彎管和閥的旁邊，以防受不穩(wěn)定流動的干擾。5.5泵聯(lián)軸器和電機聯(lián)軸器聯(lián)接以后，重新檢查其對中性；檢查電動機的轉向是否符合泵軸的轉向：從聯(lián)軸器方向看泵，為順時針方向旋轉，如果電動機轉向不符泵的轉向，必須把電動機轉向調(diào)正過來。5.6如果需要，在泵運轉以前重新調(diào)整軸封或重新裝配。6、使用、操作6.1使用、操作注意事項6.1.1泵只允許在規(guī)定的參數(shù)范圍內(nèi)運轉。6.1.2泵不允許在吐出閥門關閉或關到很小開度下運轉，否則導致泵發(fā)熱，降低壽命。如果泵是安裝在一個并了解統(tǒng)中，每臺泵都要在特定的參數(shù)下運行以保證泵的流量。6.1.3泵不能關吸入閥運行，否則使泵發(fā)生干轉，導致泵零件損壞。6.1.4泵輸送的介質不能含有空氣或氣體，否則會使泵的流量和揚程不能準確地測出，同時會產(chǎn)生研磨損壞零件。6.1.5本型泵不能輸送超過0.1%顆粒的介質，否則會降低泵的效率和零件的壽命。6.1.6絕對禁止平衡水管堵塞。檢查方法：看平衡水管里不流是否暢通，測定平衡水管處溫度是否正常。6.1.7泵在運轉時注意軸承溫度，最高溫度不得高于70℃，泵在使用過程中，必須保持油室清潔，并經(jīng)常注意加潤滑油脂或潤滑油。6.1.8有軸向竄動量的泵，檢查泵軸竄動是否在允許范圍內(nèi)。6.1.9泵的填料壓緊程度可隨時調(diào)整，調(diào)至溫升和泄漏量適宜為止。6.1.10水泵工作一定時間后進行檢修，密封環(huán)與葉輪的間隙因磨損超過最大值的兩倍時，應更換密封環(huán)。6.1.11用戶可根據(jù)現(xiàn)場實際情況及技術水平訂出比較細致的操作規(guī)程。6.1.12開泵以前按6.2條對泵進行開車前檢查。6.2啟泵前檢查6.2.1啟泵前，檢查全部螺栓、管路及儀器儀表引線的聯(lián)接是否緊固。6.2.2檢查全部儀表，閥門及儀器是否正常。6.2.3檢查油位計的油位是否正常。6.2.4泵在起動前必須用手轉動泵軸，感覺靈活。6.2.5檢查電動機的轉向是否與泵的轉向一致。6.2.6泵起動前需向泵內(nèi)注水或抽真空，并關閉出口閘閥及壓力表旋塞。6.3泵的啟動6.3.1泵啟動時注意事項：a）啟動時觀察壓力計和開關的指示，以便調(diào)整。b）泵吸入閥沒有完全打開以前不能開泵。c）啟動后，不能使吐出閥關閉或接近關閉較長時間，否則會使泵內(nèi)液體過熱。6.3.2啟泵步驟a）按6.2條內(nèi)容進行開車前檢查。b）打開泵的吸入閥和水封水管路的閥。c）關閉吐出管路的閥，使泵內(nèi)充滿液體。d）啟動電機。接著逐漸打開吐出管路的閥。e）起動水泵打開壓力表、真空表旋塞，逐漸打開出口閘閥到壓力表指針指到泵規(guī)定參數(shù)范圍的位置為止，當泵的壓力上不來時，立刻停車，以免平衡機構磨損。6.4泵運轉檢查泵運轉后，應立即按6.2條的程序每隔一定的時間檢查儀表。以此確定泵的工作是否正常，而且要檢查泵的轉速。此外，監(jiān)測泵的流量、揚程、溫度及潤滑狀況。泵在發(fā)生故障時，應停泵。且參考第7條泵的故障分析與排除進行維修。6.5停泵6.5.1關閉吸入壓力計和吐出壓力計。6.5.2慢慢關閉泵的吐出閥。6.5.3關閉電動機。6.5.4當泵停穩(wěn)后，再關閉泵的吸入閥。7、故障分析與排除故障現(xiàn)象原因分析排除方法1、水泵不吸水，吸入壓力計顯示值劇烈波動。注入水泵的水不夠。進水管與儀表等處漏氣。再往水泵內(nèi)注水，擰緊堵塞漏氣處。2、水泵不吸水，吸入壓力計顯示高度真空。底閥沒有打開或已淤塞，吸水管阻力太大，吸水高度太高。校正或更換底閥，清洗或更換吸水管，降低吸水高度。3、泵出口壓力計顯示有壓力，而水泵不出水。出水管阻力太大，旋轉方向不對，葉輪淤塞。水泵零件損壞，轉數(shù)不夠。檢查或縮短出水管，檢查電機轉向，應與泵軸轉向一致，清洗葉輪或更換零件，提高轉數(shù)。4、流量不足。水泵淤塞，密封環(huán)磨損過多，轉數(shù)不足。清洗水泵及管子，更換密封環(huán)，提高轉數(shù)。5、水泵消耗的功率過大。填料壓蓋壓得太緊，填料室發(fā)熱，泵旋轉部分發(fā)生磨擦，水泵供水量增加。擰松填料壓蓋或更換填料，檢查泵內(nèi)各旋轉零件并加以修正，調(diào)節(jié)閘閥降低流量。6、水泵內(nèi)部聲音反常，水泵不上水。流量太大，吸水管內(nèi)阻力過大，吸水高度過高。在吸水處有空氣滲入，所輸送液體溫度過高。調(diào)節(jié)閘閥降流量，檢查吸水管和底閥，降低吸水高度，擰緊堵塞漏氣處，降低輸送液體溫度。7、水泵振動泵軸與電機軸線不在同一條中心線上，臟物或水浸入軸承。把水泵和電機的軸中心線對準，清洗軸承更換潤滑脂、潤滑油。8、軸承過熱。潤滑脂、潤滑油干固或臟了，水泵軸與電機軸不在一條中心線上。檢查或清洗軸承體，更換潤滑脂、潤滑油，把軸中心對準。9、平衡水終斷，平衡室發(fā)熱，電機功率增加。水泵在大流量低揚程下運轉，平衡盤與平衡環(huán)產(chǎn)生研磨。關小出口閘閥至泵的規(guī)定參數(shù)范圍內(nèi)運轉，拆卸平衡盤與平衡環(huán)進行檢修。8、保養(yǎng)、維修8.1概述為了保持泵高效穩(wěn)定的工作狀況，泵必須經(jīng)常保養(yǎng)、維修，維修的項目和每次維修間隔時間取決于泵的工作條件和泵的運行狀況。8.2泵的維護定期檢查泵的性能（如流量、揚程、振動等）而且要做記錄，按這些記錄數(shù)據(jù)去分析泵是否工作正常，是否需要維修，或確定要修的哪一個部位。在一般條件下，如果堅持精確地測試，記錄，定期的總結記錄，那么每隔幾個月就可以得到泵是否需要維修的可靠資料。除在規(guī)定時間對泵監(jiān)測之外，下面的維護是經(jīng)常的：a）檢查泵底座、泵、電動機是否緊固，如果松動會引起泵的振動。b）檢查儀表、引線的狀況，檢查管路是否泄漏或松動，或其它形式的損壞，如果需要維修應立即檢修。c）填料壓蓋不能壓得過緊，否則會影響填料的壽命。d）軸承潤滑脂每工作100小時加注一次。8.3泵的拆卸8.3.1拆卸泵時應注意下列事項：a）按6.5條停泵程序停泵。b）將泵殼內(nèi)的液體放掉。c）如果軸承部件是稀油潤滑時，應將潤滑油放掉。d）拆去防礙拆卸的附屬管路，如平衡水管、水封水管等管路和儀器儀表。e）拆卸泵聯(lián)軸器。8.3.2拆卸順序泵的拆卸步驟應從拆下吐出側的軸承部件開始，其順序大體如下：a）擰下吐出側軸承壓蓋上的螺栓和吐出段（出水段）、填料函體（尾蓋）、軸承體三個件之間的聯(lián)接螺母，卸下軸承部件。b）擰下軸上的圓螺母，依次卸下軸承內(nèi)圈、軸承壓蓋和擋套后，卸下填料函體或尾蓋（包括填料壓蓋、填料環(huán)、填料等在內(nèi)）。c）依次卸下軸上的O型密封圈、軸套、平衡盤和鍵后，卸下吐出段或出水段（包括末級導葉、平衡環(huán)等在內(nèi)）。d）卸下末級葉輪和鍵后，卸下中段（包括導葉在內(nèi)）。按同樣方法，繼續(xù)卸下其余各級的葉輪、中段和導葉，直到卸下首級葉輪為止。e）擰下吸入段（進水段）和軸承體的聯(lián)接螺母和擰下軸承壓蓋上的螺栓后，卸下軸承部件（在這之前應預先將泵聯(lián)軸器卸下）。f）將軸從吸入段（進水段）中抽出，擰下軸上的固定螺母，依次將軸承內(nèi)圈、O型密封圈、軸套、擋套等卸下。至此拆卸工作基本完成，但在上述拆卸過程中，還有部分零件互相是聯(lián)接在一起的，一般情況下擰下聯(lián)接螺栓或螺母后即可卸下。8.4清洗和檢查8.4.1用煤油清洗全部的零件，在空氣中干燥或用布擦干。8.4.2檢查全部零件的磨損情況，對不能確保正常運轉的零件應更換新的。8.4.3檢查泵軸是否有灰塵或生銹，用千分表檢查軸的不直度（軸的徑向跳動值不大于8級精度）。8.4.4當密封間隙超過推薦值的最大值50%時，應更換密封元件。8.5泵的裝配8.5.1本型泵裝配質量的好與壞對泵的性能及運行穩(wěn)定性影響顯著。葉輪出口中心與導葉進口中心的對準，泵的轉子部分與定子部分的各個密封間隙值大小及均勻等稍有偏差，就會使水泵的性能受到影響，流量減小，揚程降低，效率差，以致降低泵的使用壽命。為此，本型泵必須有良好的同心度方能使泵運轉輕快，故在裝配時務必注意。8.5.2轉子部件技術要求：圖3轉子部件圖泵體密封環(huán)與葉輪密封環(huán)的名義徑向間隙，按下表：名義尺寸（mm）30～90＞90～120＞120～180＞180～250＞250～500＞500～800＞800～1250＞1250直徑間隙（mm）0.3～0.40.4～0.50.5～0.60.6～0.70
