這些原因包括：a.泵和電動(dòng)機(jī)未對(duì)準(zhǔn)——這無可爭辯的是泵內(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)軸器通常可以比泵或電動(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，即使在正常觀測實(shí)踐條件下這種磨損水平不足以被檢測到。誠然，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，蘇州工業(yè)離心泵效率。d.軸承磨損/故障——正如其他討論所示，潤滑不足或潤滑不當(dāng)可以加速軸承磨損并引起振動(dòng)，蘇州工業(yè)離心泵效率，蘇州工業(yè)離心泵效率。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。江蘇離心泵廠家——靖江市瑞鑫泵業(yè)有限公司。蘇州工業(yè)離心泵效率</p><div
