泵用機(jī)械密封種類繁多，型號(hào)各異，但泄漏點(diǎn)主要有五處：1)、軸套與軸間的密封；2)、動(dòng)環(huán)與軸套間的密封；3)、動(dòng)、靜環(huán)間密封；4)，赤峰格蘭富機(jī)械密封件CR64-2-2、對(duì)靜環(huán)與靜環(huán)座間的密封；5)、密封端蓋與泵體間的密封；1、安裝靜試時(shí)泄漏機(jī)械密封安裝調(diào)試好后，一般要進(jìn)行靜試，觀察泄漏量。如泄漏量較小，多為動(dòng)環(huán)或靜環(huán)密封圈存在問題；泄漏量較大時(shí)，則表明動(dòng)、靜環(huán)摩擦副間存在問題。在初步觀察泄漏量、判斷泄漏部位的基礎(chǔ)上，再手動(dòng)盤車觀察，赤峰格蘭富機(jī)械密封件CR64-2-2，若泄漏量無明顯變化則靜、動(dòng)環(huán)密封圈有問題；如盤車時(shí)泄漏量有明顯變化則可斷定是動(dòng)、靜環(huán)摩擦副存在問題；如泄漏介質(zhì)沿軸向噴射，則動(dòng)環(huán)密封圈存在問題居多，泄漏介質(zhì)向四周噴射或從水冷卻孔中漏出，則多為靜環(huán)密封圈失效。此外，泄漏通道也可同時(shí)存在，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。2、試運(yùn)轉(zhuǎn)時(shí)出現(xiàn)的泄漏泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時(shí)高速旋轉(zhuǎn)產(chǎn)生的離心力，介質(zhì)的泄漏。因此，試運(yùn)轉(zhuǎn)時(shí)機(jī)械密封泄漏在排除軸間及端蓋密封失效后，基本上都是由于動(dòng)、靜環(huán)摩擦副受破壞所致。引起摩擦副密封失效的因素主要有：1)，赤峰格蘭富機(jī)械密封件CR64-2-2、操作中，因抽空、氣蝕、憋壓等異?，F(xiàn)象，引起較大的軸向力，使動(dòng)、靜環(huán)接觸面分離。運(yùn)城格蘭富機(jī)械密封件。赤峰格蘭富機(jī)械密封件CR64-2-2</p><div

安裝程序**簡(jiǎn)化，同時(shí)密封面和密封彈性體都得到很好的保護(hù)，可防止意外的損壞。這些優(yōu)點(diǎn)也意味著可縮減密封的維修和更換時(shí)間。各種彈筒式密封幾乎都可以在市場(chǎng)上購得，因此可以減少使用中出現(xiàn)的風(fēng)險(xiǎn)因素，而且還可以節(jié)約使用普通密封件所固有的維修時(shí)間。雙重密封和液體阻隔裝置采用雙重密封面的密封來代替單一的密封件具有更高程度的防漏特性。這類雙重密封大都應(yīng)用于揮發(fā)性強(qiáng)、有毒、危險(xiǎn)和潤(rùn)滑性很差的液體。雙重密封一般有三種設(shè)計(jì)型式，每種型式都要求在雙重密封面之間使用一種液體阻隔系統(tǒng)，以防止液體或氣體外泄。比較常用的低成本雙重密封是一種以背靠背方式安裝的密封，其旋轉(zhuǎn)密封面以相反的方向排列。它往往需要一種阻隔液體，其壓力應(yīng)高于填料盒壓力，大約為20psi，這樣就可保證內(nèi)部的密封始終能得到阻隔液體的潤(rùn)滑，而且也可保證密封面達(dá)到一定的密封壓力。圖5這類密封的旋轉(zhuǎn)面采用面對(duì)面方式進(jìn)行安裝，并采用高壓或低壓阻隔液體系統(tǒng)。在結(jié)構(gòu)比較復(fù)雜的面對(duì)面型式密封中，旋轉(zhuǎn)密封面之間是以面對(duì)面方式排列的(見圖5)，它們往往在同一靜止密封面的相反方向上動(dòng)作。這類密封既可采用高壓阻隔液體系統(tǒng)，也可采用低壓阻隔液體系統(tǒng)。</p><p> 腐蝕失效機(jī)械密封因腐蝕引起的失效為數(shù)不少，常見的腐蝕類型有如下幾種。1.表面腐蝕由于腐蝕介質(zhì)的侵蝕作用，機(jī)械密封件會(huì)發(fā)生表面腐蝕，嚴(yán)重時(shí)也可發(fā)生腐蝕穿孔，彈簧件更為明顯，采用不銹鋼材料，可減輕表面腐蝕。2.點(diǎn)腐蝕彈簧套常出現(xiàn)大面積點(diǎn)蝕或區(qū)域性點(diǎn)蝕，有的導(dǎo)致穿孔，此類局部腐蝕對(duì)密封使用尚不會(huì)造成很嚴(yán)重的后果，不過大修時(shí)也應(yīng)予更換。3.晶間腐蝕碳化鎢環(huán)不銹鋼環(huán)座以銅焊連接，使用中不銹鋼座易發(fā)生晶間腐蝕，為克服敏化的影響，不銹鋼應(yīng)進(jìn)行固溶處理。4.應(yīng)力腐蝕破裂金屬焊接波紋管、彈簧等在應(yīng)力與介質(zhì)腐蝕的共同作用下，往往會(huì)發(fā)生斷裂，由于彈簧的突然斷裂而使密封失效，一般采用加大彈簧絲徑加以解決。5.縫隙腐蝕動(dòng)環(huán)的內(nèi)孔與軸套表面之間、螺釘與螺孔之間，O形環(huán)與軸套之間，由于間隙內(nèi)外介質(zhì)濃度之差而導(dǎo)致縫隙腐蝕，此外陶瓷鑲環(huán)與金屬環(huán)座間也會(huì)發(fā)生縫隙腐蝕，一般在軸套表面噴涂陶瓷，鑲環(huán)處表面涂以黏結(jié)劑以減輕縫隙腐蝕。6.電化學(xué)腐蝕異種金屬在介質(zhì)中往往引起電化學(xué)腐蝕，它使鑲環(huán)松動(dòng)，影響密封，一般亦采取在鑲接處涂黏結(jié)劑的辦法予以克服。熱損失效1.熱裂如密封面處于干摩擦、冷卻突然中斷、雜質(zhì)進(jìn)入密封面、抽空等。南宮格蘭富機(jī)械密封件。</p><div

沖洗液可以是熱水或蒸汽。九、機(jī)械密封典型失效原因分析（一）機(jī)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(jì)不合理。3、材質(zhì)選用不當(dāng)。4、密封面不平。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(qiáng)。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(dòng)、安裝間隙過大。2、泵開啟后振動(dòng)太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機(jī)械密封安裝沒有達(dá)到應(yīng)有的壓縮量。十、常見的滲漏現(xiàn)象機(jī)械密封滲漏的比例占全部維修泵的50%以上，機(jī)械密封的運(yùn)行好壞直接影響到水泵的正常運(yùn)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(dòng)量大，輔助密封與軸的過盈量大，動(dòng)環(huán)不能在軸上靈活移動(dòng)。在泵翻轉(zhuǎn)，動(dòng)、靜環(huán)磨損后，得不到補(bǔ)償位移。對(duì)策：在裝配機(jī)械密封時(shí)，軸的軸向竄動(dòng)量應(yīng)小于0．1mm，輔助密封與軸的過盈量應(yīng)適中，在保證徑向密封的同時(shí)，動(dòng)環(huán)裝配后保證能在軸上靈活移動(dòng)（把動(dòng)環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤(rùn)滑油量不足引起干摩擦或拉毛密封端面。秦皇島格蘭富機(jī)械密封件。岳陽CLS80155-744231格蘭富機(jī)械密封件</p><p
