但在處理泵的振動(dòng)問(wèn)題時(shí)卻通常是首先考慮的因素。引起振動(dòng)的這一類原因的主要原因包括：a.臨界轉(zhuǎn)速問(wèn)題——這類問(wèn)題實(shí)際上在以全速運(yùn)行的臥式泵內(nèi)是不存在的：生產(chǎn)商已對(duì)泵進(jìn)行了設(shè)計(jì)，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(dá)到自然頻率時(shí)便發(fā)生振動(dòng)和共振。)在立式泵(如具有各類長(zhǎng)度和轉(zhuǎn)頭的立式渦輪機(jī))內(nèi)，臨界轉(zhuǎn)速應(yīng)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(shí)，管道實(shí)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(wèn)題相類似?？刹捎脙煞N方法糾正臨界轉(zhuǎn)速問(wèn)題，將振動(dòng)減少至可接受水平：1.改變泵的自然頻率，這一操作應(yīng)咨詢泵生產(chǎn)商或在其協(xié)助下進(jìn)行。屬于常用方法。2.改變轉(zhuǎn)速(針對(duì)VFD系統(tǒng)時(shí)尤為有用)。通過(guò)臨界轉(zhuǎn)速"鎖定"或加速以預(yù)防機(jī)械運(yùn)轉(zhuǎn)。b.嚴(yán)重氣濁——?dú)鉂徇_(dá)到一定嚴(yán)重程度時(shí)(由NPSH或攜入的空氣引起)，內(nèi)爆的能量將引起整個(gè)裝置急劇振動(dòng)。當(dāng)然，隨著氣濁的繼續(xù)，泵輪材料將被腐蝕，振動(dòng)也進(jìn)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。</p><p> 04泵排液后中斷故障分析：吸入管路漏氣；灌泵時(shí)吸入側(cè)氣體未排盡；吸入側(cè)突然被異物堵住，或吸入口濾器堵塞；吸入管脫水，大量氣體吸入解決方法：檢查吸入側(cè)連接處及填料函的密封情況；重新灌泵；停泵，清洗濾芯，疏通吸入管路；檢查吸入管路是否破裂。并聯(lián)進(jìn)口管線上的閥門是否打開(kāi)（不常用的管線）。05流量不足故障分析：系統(tǒng)凈揚(yáng)程增加；阻力損失增加；口環(huán)及葉輪磨損過(guò)大；其它地方漏液；泵葉輪堵塞、磨損、腐蝕。解決方法：檢查液位高度和系統(tǒng)壓力；檢察管路及止回閥等有無(wú)故障；更換口環(huán)及葉輪；檢查軸封等地方；清洗、檢查、調(diào)換。06揚(yáng)程不夠故障分析：葉輪裝反（雙吸泵）；液體密度、黏度與設(shè)計(jì)條件不符；操作流量太大。解決方法：檢查葉輪；檢查有關(guān)物理性質(zhì)；調(diào)解閥門、減少硫量。07運(yùn)行超負(fù)荷故障分析：動(dòng)機(jī)質(zhì)量差，定轉(zhuǎn)子摩擦；葉輪與承磨環(huán)、葉輪與泵殼有摩擦；液體密度增加；填料壓得太緊或干摩擦；軸承損壞；轉(zhuǎn)速過(guò)高；泵軸彎曲；軸向力平衡裝置失效；聯(lián)軸器對(duì)中不良或軸向間隙太??；輸送液體黏度過(guò)高或密度過(guò)大。解決方法：檢查更換電動(dòng)機(jī)；檢查泵內(nèi)零件并加以修理；檢查密度；放松填料、檢查水封管；檢查與更換軸承；檢察原動(dòng)機(jī)轉(zhuǎn)速與電源；校正泵軸。江蘇質(zhì)量離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div

離心泵的特性曲線是泵本身固有的特性，它與外界使用情況無(wú)關(guān)。但是，一旦泵被安排在一定的管路系統(tǒng)中工作時(shí)，其實(shí)際工作情況就不僅與離心泵本身的特性有關(guān)，而且還取決于管路的工作特性。所以，要選好和用好離心泵，就還要同時(shí)考慮到管路的特性。 </p> <p> 在特定管路中輸送液體時(shí)，管路所需壓頭He隨著流量Qe的平方而變化。將此關(guān)系繪在坐標(biāo)紙上即為相應(yīng)管路特性曲線。 </p> <p> 若將離心泵的特性曲線與其所在管路特性曲線繪于同一坐標(biāo)紙上，如上圖所示，此兩線交點(diǎn)M稱為泵的工作點(diǎn)。選泵時(shí)，要求工作點(diǎn)所對(duì)應(yīng)的流量和壓頭既能滿足管路系統(tǒng)的要求，又正好是離心泵所提供的，即Q = Qe，H = He。江蘇地區(qū)銷售離心泵——靖江市瑞鑫泵業(yè)有限公司。徐州耐磨離心泵配件</p><p

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(dòng)時(shí)，必須先把閘閥關(guān)閉，灌水。水位超過(guò)葉輪部位以上，排出離心泵中的空氣，才可啟動(dòng)。啟動(dòng)后，葉輪周圍形成真空，把水向上吸，其閘閥可自動(dòng)打開(kāi)，把水提起。因此，必須先閉閘閥。 </p> <p> 振動(dòng)分析 </p> <p> 離心泵的轉(zhuǎn)子不平衡與不對(duì)中。這個(gè)問(wèn)題在離心泵的振動(dòng)問(wèn)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(dòng)平衡：一般也稱為單面平衡和雙面平衡。其區(qū)別就是：?jiǎn)蚊嫫胶馐窃谝粋€(gè)校正面進(jìn)行校正平衡，而雙面平衡是在兩個(gè)校正面上進(jìn)行校正。常州耐酸離心泵廠家</p><p
