12、須具有足夠的強(qiáng)度，基礎(chǔ)的質(zhì)量約等于機(jī)組質(zhì)量的35倍。(2)檢查水泵和電機(jī)，檢查泵的零件是否有嚴(yán)重磕碰現(xiàn)象。(3)檢查泵的零配件是否缺少或損壞。(4)準(zhǔn)備工具及起重機(jī)械。安裝順序：(1)在底座下面放置鋼的墊鐵和楔鐵。用起重吊鉤吊住底座的四個(gè)角，把底座吊在地基上方，慢慢地把底座放在每一個(gè)預(yù)制好的地腳螺栓孔的位置上。(2)找平底座，向地腳處灌漿，達(dá)到凝固強(qiáng)度后，擰緊地腳螺栓。(3)設(shè)備調(diào)整。泵與電機(jī)聯(lián)軸器之間應(yīng)有間隙，一般間隙應(yīng)有36毫米左右。水泵與電機(jī)的軸線應(yīng)重合，可用塞尺測量兩聯(lián)軸器端面問隙的均勻度，其允差為0.06毫米，可用直尺在兩聯(lián)軸器圓周各個(gè)方向進(jìn)行測量，兩聯(lián)軸器外圓表面間隙允差008毫米

13、。如不符以上要求，可用調(diào)整墊進(jìn)行調(diào)整。管道安裝及注意事項(xiàng)：(1)泵的出水口必須安裝壓力表，閘閥及止回閥。進(jìn)水處應(yīng)安裝真空表、底閥（用真空泵引水可不安裝底閥）。(2)進(jìn)水管道的進(jìn)口處應(yīng)安裝過濾網(wǎng)，防止大的顆粒進(jìn)入泵中，損壞設(shè)備。(3)不得將管路重量壓在泵上，使泵受力。泵停后，不得使泵承受管路中水的重力。(4)泵的平衡水管是連接進(jìn)水段和出水段的一根管，它起著平衡軸向力的作用，絕對不允許堵塞，一般泵出廠時(shí)已連接好，用戶不需要再安裝調(diào)整。(5)水封管是連接進(jìn)水段填料腔和填料函體填料腔的一根管，它起到防止泵內(nèi)進(jìn)氣、水潤滑及水冷卻的作用。(6)必須采用不小于水泵進(jìn)水口徑的管子進(jìn)行安裝，否則會(huì)影響水泵的性能

14、。(7)管道在距離1米范圍內(nèi)盡可能不拐彎，以減少阻力損失。(8)管道安裝完畢后，必須進(jìn)行沖洗方可與泵連接，防止焊渣等雜質(zhì)進(jìn)入泵內(nèi)，損壞葉輪。五、操作與使用啟動(dòng)前(1)用手轉(zhuǎn)動(dòng)聯(lián)軸器，泵的轉(zhuǎn)動(dòng)部分旋轉(zhuǎn)應(yīng)該靈活均勻。每次啟動(dòng)泵都應(yīng)重復(fù)進(jìn)行此操作，發(fā)現(xiàn)卡死現(xiàn)象應(yīng)即時(shí)維修。(2)向泵內(nèi)注滿水或抽出泵內(nèi)空氣，并關(guān)閉泵出口管路上的閘閥和壓力表旋塞。要保證泵內(nèi)充滿水，無空氣窩存。(3)瞬間啟動(dòng)一下電機(jī)，檢查泵的旋轉(zhuǎn)方向是否正確。水泵的選裝方向：從電機(jī)方向看泵為順時(shí)針方向選裝。(4)啟動(dòng)泵后，打開壓力表旋塞、真空表旋塞，并逐漸打開泵出口管路上的閘閥，待壓力表顯示壓力滿足要求即可。運(yùn)轉(zhuǎn)(1)注意水泵軸承溫度，其

15、最高溫度不得高于70，溫升不得高于35。(2)填料的松緊程度應(yīng)適應(yīng)，每分鐘的滲水量為1020滴，否則應(yīng)調(diào)整填料壓蓋。但填料不能壓的太緊，否則會(huì)使電機(jī)電流升高或燒壞填料。(3)定期檢查聯(lián)軸器，泵、電聯(lián)軸器是否出現(xiàn)裂痕，螺栓是否松動(dòng)等現(xiàn)象。(4)水泵每工作1000小時(shí)，應(yīng)進(jìn)行檢修，葉輪與密封環(huán)的間隙因磨損超過最大值的兩倍時(shí)，應(yīng)更換密封環(huán)。(5)泵只允許在說明書規(guī)定的參數(shù)范圍內(nèi)運(yùn)轉(zhuǎn)。禁止超大流量運(yùn)行，以免超負(fù)荷及振動(dòng)、噪音加劇。(6)泵不允許在出口閥門關(guān)閉或很小開度下長時(shí)間運(yùn)轉(zhuǎn)，否則導(dǎo)致泵發(fā)熱，降低壽命。(7)泵不能關(guān)吸入閥運(yùn)行，也不能用吸入閥來調(diào)節(jié)流量，以免產(chǎn)生汽蝕而損壞泵。(8)運(yùn)轉(zhuǎn)過程中，發(fā)現(xiàn)

16、噪音或不尋常的聲音，應(yīng)立即停車，檢查其原因。(9)用戶應(yīng)根據(jù)說明書要求和現(xiàn)場情況，定制出合理的操作規(guī)程。停車 慢慢關(guān)閉出水管路上的閘閥和壓力表旋塞，進(jìn)水口管路上的真空表旋塞，然后切斷電動(dòng)機(jī)電源。六、泵的維護(hù)與保養(yǎng)1、用戶應(yīng)制定出泵的維護(hù)保養(yǎng)制度(1)檢查泵的底座、泵的電動(dòng)機(jī)固定螺栓是否松動(dòng)。(2)檢查儀表、引線的狀況是否損壞或老化，檢查管路是否泄漏或松動(dòng)。(3)水泵工作的第一個(gè)月內(nèi)，經(jīng)過100小時(shí)后軸承應(yīng)當(dāng)換油一次，以后每工作2000小時(shí)換油一次。(4)冬季暫停停泵時(shí)，應(yīng)將泵底部所有絲堵擰開，把泵內(nèi)的水放掉避免將水泵凍壞。(5)長期不用泵時(shí)，應(yīng)將泵卸掉，拆開，將零件涂防銹油，妥善保存。(6)每

17、次停機(jī)后，再啟動(dòng)泵時(shí)，先用手轉(zhuǎn)動(dòng)聯(lián)軸器，看泵的轉(zhuǎn)子轉(zhuǎn)動(dòng)是否靈活，有無卡死現(xiàn)象。(7)每次啟動(dòng)泵時(shí)，應(yīng)先關(guān)閉出水閘閥及壓力表旋塞，泵啟動(dòng)后，再逐漸打開出水閘閥及壓力表旋塞。(8)定期檢查泵的性能及運(yùn)行情況，并做詳細(xì)記錄，如發(fā)現(xiàn)問題應(yīng)立即維修。七、可能發(fā)生的故障及其解決方法故障原因解決方法1、泵不出水，壓力表及真空表指針劇烈跳動(dòng)。注入水泵的水不夠，進(jìn)水管路與儀表漏氣，進(jìn)水管路有空氣窩存。再往水泵內(nèi)注水，擰緊漏氣處的螺栓或旋塞，調(diào)整進(jìn)水管路。2、水泵不出水，真空表表示高度真空。底閥沒打開或已淤塞，吸水管路阻力太大，吸水高度太大。檢查或更換底閥，清洗或更換吸水管路，降低吸水高度。3、軸承或軸瓦過熱。軸

18、承潤滑不良，泵軸線與電動(dòng)機(jī)軸線不重合，冷卻水堵塞，軸瓦損傷。清洗、檢查軸承，注入適量的潤滑油，把兩軸線對準(zhǔn)，疏通冷卻水管路，修復(fù)軸瓦。4、從壓力表看泵出水處有壓力但泵仍不出水。出水管路阻力太大，旋轉(zhuǎn)方向不對，葉輪流道淤塞，水泵轉(zhuǎn)數(shù)不夠。檢查或縮短出水管路，改變旋塞方向，清理葉輪流道，增加水泵轉(zhuǎn)數(shù)到設(shè)計(jì)值。5、流量低于設(shè)計(jì)值。水泵流道、管路被堵塞，密封處間隙過大，轉(zhuǎn)數(shù)不足，管徑細(xì)。清理水泵及管路，更換密封環(huán)，增加水泵軸的轉(zhuǎn)數(shù)。6、泵消耗功率過大。填料壓得過緊，填料函體處發(fā)熱，葉輪摩擦，泵出水量增加，平衡盤摩擦。調(diào)整填料壓蓋，更換填料，調(diào)整出水管路閘閥或增加出水管路阻力，更換平衡盤、平衡環(huán)。7、泵

19、聲音反常，不出水。流量過大，吸水管路阻力大，吸水高度過高，吸水管路上有空氣滲入，所輸送液體溫度過高。降低流量；檢查吸水管路及底閥，降低吸水高度；擰緊進(jìn)漏氣處螺栓旋塞。降低液體溫度。8、泵聲音反常并發(fā)生振動(dòng)。泵流量過大；泵安裝高度過高產(chǎn)生汽蝕；泵軸線與電動(dòng)機(jī)軸線不重合；聯(lián)軸器彈性圈損壞，地腳松動(dòng)，軸承損壞。降低流量；降低安裝高度；檢查校正水泵與電動(dòng)機(jī)聯(lián)軸器處圓及端面間隙；更換彈性圈，更換軸承。9、平衡水中斷，平衡室發(fā)熱，電機(jī)功率增加。泵在大流量、低揚(yáng)程點(diǎn)運(yùn)轉(zhuǎn)，平衡盤與平衡環(huán)產(chǎn)生研磨。關(guān)小出口閘閥至設(shè)計(jì)工況運(yùn)轉(zhuǎn)，拆卸平衡盤進(jìn)行檢修或更換。八、DA泵外形圖DA型泵外形尺寸表泵型級(jí)數(shù)泵外型尺寸進(jìn)水法蘭
