id="mmjb22r" class="box"><p><p> 泵體也稱泵殼，它是水泵的主體。起到支撐固定作用，并與安裝軸承的托架相連接。 </p> <p> 泵軸的作用是借聯(lián)軸器和電動機相連接，將電動機的轉(zhuǎn)矩傳給葉輪，所以它是傳遞機械能的主要部件。 </p> <p> 滑動軸承使用的是透明油作潤滑劑的，加油到油位線。太多油要沿泵軸滲出，太少軸承又要過熱燒壞造成事件！在水泵運行過程中軸承的溫度比較高在85度，一般運行在60度左右。 </p> <p> <br /> </p> <p> 密封環(huán)又稱減漏環(huán)。 </p> <p>

離心泵的常見故障機解決辦法：故障四：離心泵流量不足（1）系統(tǒng)靜揚程增加。處理方法是檢查液體高度和系統(tǒng)壓力。（2）阻力損失增加。處理方法是檢查管路及止逆閥等障礙。（3）殼體和葉輪耐磨環(huán)磨損過大。處理方法是更換或修理耐磨環(huán)及葉輪。（4）其他部位漏液。處理方法是檢查軸封等部位。（5）泵葉輪堵塞、磨損、腐蝕。處理方法是清洗、檢查、調(diào)換。故障五：離心泵揚程不夠（1）葉輪裝反（雙吸輪）。處理方法是檢查葉輪。（2）液體密度、粘度與設(shè)計條件不符。處理方法是檢查液體的性質(zhì)。（3）操作時流量太大。處理方法是減少流量。故障六：運行過程**耗過大（1）葉輪與耐磨環(huán)、葉輪與殼有磨檫。處理方法是檢查并修理。（2）液體密度增加。處理方法是檢查液體密度。（3）填料壓得太緊或干磨擦。處理方法是放松填料，檢查水封管。（4）軸承損壞。處理方法是檢查修理或更換軸承。故障七：發(fā)生氣縛現(xiàn)象氣縛主要是由于離心泵在啟動前未充滿液體，泵殼內(nèi)存在空氣，空氣密度小，所產(chǎn)生的離心力也很小，此時在吸入口所形成的真空度不足以將液體吸入泵內(nèi)，泵氣動后不能輸送液體的現(xiàn)象。原因分析：①啟動前，未進行灌泵排氣，致使空氣竄入泵殼。②殼體的密封不嚴，使空氣竄入。蘇州離心泵揚程離心泵銷售廠家就找靖江市瑞鑫泵業(yè)有限公司。</p><div

但在處理泵的振動問題時卻通常是首先考慮的因素。引起振動的這一類原因的主要原因包括：a.臨界轉(zhuǎn)速問題——這類問題實際上在以全速運行的臥式泵內(nèi)是不存在的：生產(chǎn)商已對泵進行了設(shè)計，因此其臨界轉(zhuǎn)速將高出高轉(zhuǎn)速。("臨界轉(zhuǎn)速"指激起旋轉(zhuǎn)設(shè)備自然頻率的理論角速度。旋轉(zhuǎn)速度達到自然頻率時便發(fā)生振動和共振。)在立式泵(如具有各類長度和轉(zhuǎn)頭的立式渦輪機)內(nèi)，臨界轉(zhuǎn)速應在制造之前予以考慮。在臥式泵內(nèi)，臨界轉(zhuǎn)速通常由超速、缺少管道支撐件或未考慮的多泵組引起。(缺少管道支撐件時，管道實際上成為了"泵的一部分"，且系統(tǒng)的臨界轉(zhuǎn)速與泵的臨界轉(zhuǎn)速不同。)這與下文將討論的外部原因引起的問題相類似?？刹捎脙煞N方法糾正臨界轉(zhuǎn)速問題，將振動減少至可接受水平：1.改變泵的自然頻率，這一操作應咨詢泵生產(chǎn)商或在其協(xié)助下進行。屬于常用方法。2.改變轉(zhuǎn)速(針對VFD系統(tǒng)時尤為有用)。通過臨界轉(zhuǎn)速"鎖定"或加速以預防機械運轉(zhuǎn)。b.嚴重氣濁——氣濁達到一定嚴重程度時(由NPSH或攜入的空氣引起)，內(nèi)爆的能量將引起整個裝置急劇振動。當然，隨著氣濁的繼續(xù)，泵輪材料將被腐蝕，振動也進一步加劇。合理選用泵則可避免此類情況出現(xiàn)，但隨著系統(tǒng)老化以及管道改變這類情況仍可發(fā)生。江蘇地區(qū)離心泵廠家——靖江市瑞鑫泵業(yè)有限公司。</p><div

離心泵是靠葉輪離心力形成真空的吸力把水提起，所以，離心泵啟動時，必須先把閘閥關(guān)閉，灌水。水位超過葉輪部位以上，排出離心泵中的空氣，才可啟動。啟動后，葉輪周圍形成真空，把水向上吸，其閘閥可自動打開，把水提起。因此，必須先閉閘閥。 </p> <p> 振動分析 </p> <p> 離心泵的轉(zhuǎn)子不平衡與不對中。這個問題在離心泵的振動問題中所占比例較大，約為80%的比例。造成離心泵轉(zhuǎn)子不平衡的因素：材料阻止不均勻、零件結(jié)構(gòu)不合格，造成轉(zhuǎn)子質(zhì)量中心線與轉(zhuǎn)軸中心線不重合產(chǎn)生偏心據(jù)形成的不平衡。校正離心泵的轉(zhuǎn)子不平衡又可分為兩。靜平衡與動平衡：一般也稱為單面平衡和雙面平衡。其區(qū)別就是：單面平衡是在一個校正面進行校正平衡，而雙面平衡是在兩個校正面上進行校正。離心泵廠家，歡迎您的來電——靖江市瑞鑫泵業(yè)有限公司。南京離心泵類型</p><p

對軸承的檢查以及磨損軌跡和滾道內(nèi)的"剝落"將有助于確定是否有外來力加速磨損并促使振動發(fā)生。e.堵塞——泵堵塞后并不總會產(chǎn)生過量振動，但其發(fā)生的頻率還是很高。如果泵輪部件發(fā)生堵塞(不論是部分堵塞還是全部堵塞)，泵送的液體將減少并產(chǎn)生振動。拆卸泵以檢查其是否堵塞之前，建議檢查電動機的電流消耗。堵塞的泵輪所消耗的安培數(shù)將比預計更低，除非堵塞產(chǎn)生的不平衡(和振動)足以使泵輪和泵殼之間產(chǎn)生摩擦。(在這種情況下，振動極有可能伴隨摩擦和磨削噪音產(chǎn)生且安培消耗量也會增加。)外部原因引起的振動經(jīng)驗表明外部原因引起的問題是絕大多數(shù)振動產(chǎn)生的原因。a.管道應變(泵和管道之間未對準)——管道應變(以及泵與電動機之間未對準)無可爭辯地是引起泵振動的首要原因，且在排查泵振動原因時應首先關(guān)注這個原因。引入水之后考慮調(diào)整管支架極為重要。水的重量可能相當大，排空時支撐恰當?shù)墓艿涝跐M水之后可能需要進行調(diào)整。水的重量可能引起足夠應變，導致振動，但同樣也導致束縛和未對準或重大故障。b.基礎(chǔ)或錨固不牢——如果泵的基礎(chǔ)不平或基板緊固或灌漿不當，(如"軟底腳"的情況一樣)有可能且會產(chǎn)生振動。雖然在啟動時將立即出現(xiàn)這種情況，但隨時間的推移和系統(tǒng)的穩(wěn)定。南京離心泵類型</p><p
