離心泵是利用葉輪旋轉(zhuǎn)而使水發(fā)生離心運(yùn)動(dòng)來(lái)工作的。水泵在啟動(dòng)前，必須使泵殼和吸水管內(nèi)充滿(mǎn)水，然后啟動(dòng)電機(jī)，使泵軸帶動(dòng)葉輪和水做高速旋轉(zhuǎn)運(yùn)動(dòng)，水發(fā)生離心運(yùn)動(dòng)，被甩向葉輪外緣，經(jīng)蝸形泵殼的流道流入水泵的壓水管路。 </p> <p> 離心泵的基本構(gòu)造是由六部分組成的分別是葉輪，泵體，泵軸，軸承，密封環(huán)，填料函。 </p> <p> 葉輪是離心泵的主要部分，它轉(zhuǎn)速高出力大，葉輪上的葉片又起到主要作用，葉輪在裝配前要通過(guò)靜平衡實(shí)驗(yàn)。葉輪上的內(nèi)外表面要求光滑，以減少水流的摩擦損失。 </p><p> 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(lèi)原因的主要原因包括：a.臨界轉(zhuǎn)速問(wèn)題——這類(lèi)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(lèi)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(lèi)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(xún)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(lèi)情況出現(xiàn)，但隨著系統(tǒng)老化以及管道改變這類(lèi)情況仍可發(fā)生。靖江市瑞鑫泵業(yè)有限公司——給您質(zhì)量服務(wù)。</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(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?chē)纬烧婵?，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>
