吸入式離心泵（非自灌式離心泵）：泵軸高于吸水池池面。啟動(dòng)前，需要先用水灌滿泵殼和吸水管道，然后驅(qū)動(dòng)電機(jī)，使葉輪高速旋轉(zhuǎn)運(yùn)動(dòng)，水受到離心力作用被甩出葉輪，葉輪中心形成負(fù)壓，吸水池中水在大氣壓作用下進(jìn)入葉輪，又受到高速旋轉(zhuǎn)的葉輪作用，被甩出葉輪進(jìn)入壓水管道。 </p> <p>

但在處理泵的振動(dòng)問題時(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)速問題——這類問題實(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題相類似?？刹捎脙煞N方法糾正臨界轉(zhuǎn)速問題，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。江蘇地區(qū)生產(chǎn)離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div

泵軸的作用是借聯(lián)軸器和電動(dòng)機(jī)相連接，將電動(dòng)機(jī)的轉(zhuǎn)矩傳給葉輪，所以它是傳遞機(jī)械能的主要部件。 </p> <p> 滑動(dòng)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(yùn)行過程中軸承的溫度比較高在85度，一般運(yùn)行在60度左右。 </p> <p> <br /> </p> <p> 密封環(huán)又稱減漏環(huán)。 </p> <p> 填料函主要由填料、水封環(huán)、填料筒、填料壓蓋、水封管組成。填料函的作用主要是為了封閉泵殼與泵軸之間的空隙，不讓泵內(nèi)的水流流到外面來也不讓外面的空氣進(jìn)入到泵內(nèi)。始終保持水泵內(nèi)的真空！當(dāng)泵軸與填料摩擦產(chǎn)生熱量就要靠水封管住水到水封圈內(nèi)使填料冷卻！保持水泵的正常運(yùn)行。所以在水泵的運(yùn)行巡回檢查過程中對(duì)填料函的檢查是特別要注意！在運(yùn)行600個(gè)小時(shí)左右就要對(duì)填料進(jìn)行更換。

安裝原因：基礎(chǔ)螺栓松脫、校調(diào)的水平度沒有調(diào)整好，在離心泵工作之前，要檢查一下其基礎(chǔ)螺栓是否有松動(dòng)的現(xiàn)象，以及離心泵的安裝是否水平。這些也會(huì)造成離心泵在工作的時(shí)候發(fā)生振動(dòng)的情況。 </p> <p> 離心泵內(nèi)有異物。在離心泵工作之前，要檢查下泵內(nèi)部，由于長期使用，在離心泵的內(nèi)部可能存在一些例如水中的雜草等異物。 </p> <p> 由于長時(shí)間的使用造成離心泵內(nèi)部的氣蝕穿孔。 </p> <p> 離心泵的設(shè)計(jì)方面存在不合理的情況，例如零件大小尺寸等問題。不過這種情況相對(duì)較少。離心泵在出廠之前，都會(huì)在車間內(nèi)部進(jìn)行多次的檢測工作，以保證出廠離心泵的合格率。安徽耐磨離心泵參數(shù)</p><p
