沖洗液可以是熱水或蒸汽。九，岳陽CLS60157-744231格蘭富機械密封件、機械密封典型失效原因分析（一）機械密封本身問題1、鑲裝不到位或不平整。2、載荷系數(shù)太大或端面比壓設(shè)計不合理。3、材質(zhì)選用不當(dāng)。4、密封面不平，岳陽CLS60157-744231格蘭富機械密封件。5、密封面太寬或太窄。（二）輔助系統(tǒng)問題1、工況條件復(fù)雜，但沒有沖洗等輔助設(shè)施。2、沖洗管堵塞。3、冷卻管結(jié)垢。（三）介質(zhì)及工作條件問題1、介質(zhì)腐蝕性強。2、介質(zhì)中有固體顆粒。3、設(shè)備抽空。4、密封面結(jié)晶。5、介質(zhì)粘度太大。（四）泵的問題1、軸的加工精度不佳、串軸、跳動、安裝間隙過大。2、泵開啟后振動太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機械密封安裝沒有達到應(yīng)有的壓縮量。十、常見的滲漏現(xiàn)象機械密封滲漏的比例占全部維修泵的50%以上，機械密封的運行好壞直接影響到水泵的正常運行，現(xiàn)總結(jié)分析如下：1、周期性滲漏（1）泵轉(zhuǎn)子軸向竄動量大，輔助密封與軸的過盈量大，動環(huán)不能在軸上靈活移動。在泵翻轉(zhuǎn)，動、靜環(huán)磨損后，得不到補償位移。對策：在裝配機械密封時，軸的軸向竄動量應(yīng)小于0．1mm，岳陽CLS60157-744231格蘭富機械密封件，輔助密封與軸的過盈量應(yīng)適中，在保證徑向密封的同時，動環(huán)裝配后保證能在軸上靈活移動（把動環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤滑油量不足引起干摩擦或拉毛密封端面。懷化格蘭富機械密封件。岳陽CLS60157-744231格蘭富機械密封件</p><div

機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，機械密封失效導(dǎo)致泵的故障占設(shè)備故障率的50%以上，所以有必要對離心泵的機械密封泄漏進行分析改進，以降低泵的故障率。一、離心泵工作原理及機械密封裝置的作用離心泵通過電機、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，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，中心處形成了低壓區(qū)，由于進泵前的液體壓強大于泵吸入口處的壓強，在壓強差的作用下，液體便經(jīng)吸入管連續(xù)地吸入泵內(nèi)，以補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。泵軸穿過泵殼時，動靜之間有間隙存在時，泵內(nèi)的液體就會從間隙漏至泵外，若吸入端是真空，則外界空氣會漏入泵內(nèi)，嚴重影響泵的工作，為了減少泄漏，一般在動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械密封。二、機械密封原理機械密封是一種依靠彈性元件對動、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到密封的軸向端面密封裝置。機械密封通常由靜環(huán)、動環(huán)、壓緊元件和密封元件組成。長春格蘭富機械密封件TP125-420/4遼寧格蘭富機械密封件。</p><div
