機(jī)械密封是離心泵的主要易損件之一，因而泵的故障多數(shù)是由密封失效所導(dǎo)致的。據(jù)統(tǒng)計(jì)，機(jī)械密封失效導(dǎo)致泵的故障占設(shè)備故障率的50%以上，所以有必要對(duì)離心泵的機(jī)械密封泄漏進(jìn)行分析改進(jìn)，以降低泵的故障率。一、離心泵工作原理及機(jī)械密封裝置的作用離心泵通過(guò)電機(jī)、聯(lián)軸器，使其葉輪高速旋轉(zhuǎn)，在葉片之間的液體受到葉片的推動(dòng)，在離心力的作用下，不斷地從中心被甩向四周，當(dāng)泵內(nèi)液體從葉輪中心被拋向邊緣時(shí)，中心處形成了低壓區(qū)，由于進(jìn)泵前的液體壓強(qiáng)大于泵吸入口處的壓強(qiáng)，在壓強(qiáng)差的作用下，液體便經(jīng)吸入管連續(xù)地吸入泵內(nèi)，以補(bǔ)充被排出液體的位置，只要葉輪不停地旋轉(zhuǎn)，液體便不斷地吸入和排出。泵軸穿過(guò)泵殼時(shí)，動(dòng)靜之間有間隙存在時(shí)，泵內(nèi)的液體就會(huì)從間隙漏至泵外，若吸入端是真空，則外界空氣會(huì)漏入泵內(nèi)，嚴(yán)重影響泵的工作，為了減少泄漏，一般在動(dòng)靜間隙處裝有軸端密封裝置。軸封裝置是離心泵的重要部件，它直接關(guān)系到離心泵能否正常工作。現(xiàn)在軸封裝置一般采用機(jī)械密封。二、機(jī)械密封原理機(jī)械密封是一種依靠彈性元件對(duì)動(dòng)、靜環(huán)端面密封副的預(yù)緊和介質(zhì)壓力與彈性元件壓力的壓緊而達(dá)到密封的軸向端面密封裝置。機(jī)械密封通常由靜環(huán)、動(dòng)環(huán)、壓緊元件和密封元件組成。銅仁CLS20709-722231格蘭富機(jī)械密封件丹東格蘭富機(jī)械密封件。</p><div
