如何消除離心泵的軸向力？安裝軸向力平衡裝置可消除軸向力。（1）單級(jí)泵可在葉輪上開平衡孔。多級(jí)泵的葉輪可對(duì)稱安裝。裝平衡盤，如車間的G-020A/B就采用的是平衡盤。采用平衡管平衡掉各葉輪間的壓力等。.13、軸向力對(duì)泵的正常運(yùn)行有什么害處？由于軸向力的作用，可以使葉輪產(chǎn)生位移，改變了葉輪和溢流道德同心度，使流量減少，揚(yáng)程降低，嚴(yán)重時(shí)葉輪和泵體發(fā)生摩擦，直至發(fā)生設(shè)備事件。14、如何切換離心泵？（1）做好啟動(dòng)泵前的各種準(zhǔn)備后，打開入口閥，引入液體。啟動(dòng)后，待泵的轉(zhuǎn)速、聲音、泵體壓力等正常后再打開出口閥（3）泵的流量正常，壓力平穩(wěn)時(shí)關(guān)閉運(yùn)行泵的出口閥。（4）盡量減少因切換泵造成的流量、壓力波動(dòng)，維持生產(chǎn)的正常進(jìn)行。（5）檢查啟動(dòng)泵的泄漏、潤(rùn)滑等情況。15、離心泵的軸承溫度為什么會(huì)升高？（1）因?yàn)闈?rùn)滑油位過低，進(jìn)入軸承的油量少，使軸承不能充分潤(rùn)滑，所以泵在旋轉(zhuǎn)后產(chǎn)生的熱量不能被潤(rùn)滑油帶走。（3）因油孔或油溝堵塞，供油中斷，軸承形成干磨（4）滾動(dòng)軸承的滾動(dòng)體卡死，不能滾動(dòng)。（5）軸承箱進(jìn)水或進(jìn)蒸汽，潤(rùn)滑油被污染，起不到潤(rùn)滑作用。<br>安徽工業(yè)離心泵效率離心泵公司——靖江市瑞鑫泵業(yè)有限公司。</p><div

這些原因包括：a.泵和電動(dòng)機(jī)未對(duì)準(zhǔn)——這無可爭(zhēng)辯的是泵內(nèi)產(chǎn)生振動(dòng)的常見原因(其他原因，參考"外部原因引起的振動(dòng)")。應(yīng)該注意的是，按照泵生產(chǎn)商建議(而非聯(lián)軸器生產(chǎn)商的限制范圍)進(jìn)行校準(zhǔn)極為重要。(聯(lián)軸器通?？梢员缺没螂妱?dòng)機(jī)承受的未校準(zhǔn)值更大，但是負(fù)荷將傳送至泵或電動(dòng)機(jī)。)b.旋轉(zhuǎn)不當(dāng)——雖然在方向錯(cuò)誤的情況下泵也將旋轉(zhuǎn)，但是流量和轉(zhuǎn)頭將減少，且由于流體動(dòng)力學(xué)可能產(chǎn)生振動(dòng)。旋轉(zhuǎn)應(yīng)進(jìn)行檢查并校正。(改變?nèi)嚯妱?dòng)機(jī)的任意兩根導(dǎo)線，并在確認(rèn)泵能以預(yù)期旋轉(zhuǎn)運(yùn)行后檢查電動(dòng)機(jī)上的標(biāo)示牌以糾正單相電動(dòng)機(jī)上的導(dǎo)線。)c.曲軸——曲軸可能由一些與場(chǎng)地有關(guān)的問題引起并能導(dǎo)致振動(dòng)產(chǎn)生。通常情況下，曲軸將不相等負(fù)荷傳遞至軸承和閥座并引起過早磨損，即使在正常觀測(cè)實(shí)踐條件下這種磨損水平不足以被檢測(cè)到。誠(chéng)然，在底腳固定框架式泵上檢查軸的準(zhǔn)確度或"擺度"相對(duì)較容易，因?yàn)榭蚣苄纬闪艘粋€(gè)平臺(tái)，便于檢查。所有故障部件的檢查通常將顯示引起故障的原因，包括在閥座和軸承內(nèi)的故障原因。d.軸承磨損/故障——正如其他討論所示，潤(rùn)滑不足或潤(rùn)滑不當(dāng)可以加速軸承磨損并引起振動(dòng)。但是即使是在"完好"條件下，軸承也將出現(xiàn)磨損并因疲勞而出現(xiàn)故障。</p><p>

對(duì)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(dòng)發(fā)生。e.堵塞——泵堵塞后并不總會(huì)產(chǎn)生過量振動(dòng)，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(dòng)。拆卸泵以檢查其是否堵塞之前，建議檢查電動(dòng)機(jī)的電流消耗。堵塞的泵輪所消耗的安培數(shù)將比預(yù)計(jì)更低，除非堵塞產(chǎn)生的不平衡(和振動(dòng))足以使泵輪和泵殼之間產(chǎn)生摩擦。(在這種情況下，振動(dòng)極有可能伴隨摩擦和磨削噪音產(chǎn)生且安培消耗量也會(huì)增加。)外部原因引起的振動(dòng)經(jīng)驗(yàn)表明外部原因引起的問題是絕大多數(shù)振動(dòng)產(chǎn)生的原因。a.管道應(yīng)變(泵和管道之間未對(duì)準(zhǔn))——管道應(yīng)變(以及泵與電動(dòng)機(jī)之間未對(duì)準(zhǔn))無可爭(zhēng)辯地是引起泵振動(dòng)的首要原因，且在排查泵振動(dòng)原因時(shí)應(yīng)首先關(guān)注這個(gè)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(dāng)大，排空時(shí)支撐恰當(dāng)?shù)墓艿涝跐M水之后可能需要進(jìn)行調(diào)整。水的重量可能引起足夠應(yīng)變，導(dǎo)致振動(dòng)，但同樣也導(dǎo)致束縛和未對(duì)準(zhǔn)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(dāng)，(如"軟底腳"的情況一樣)有可能且會(huì)產(chǎn)生振動(dòng)。雖然在啟動(dòng)時(shí)將立即出現(xiàn)這種情況，但隨時(shí)間的推移和系統(tǒng)的穩(wěn)定。蘇州耐酸離心泵維修</p><p
