腐蝕失效機(jī)械密封因腐蝕引起的失效為數(shù)不少，常見(jiàn)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(guò)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。</p><p> 防止工作介質(zhì)從泵內(nèi)泄漏出來(lái)或者防止外界雜質(zhì)或空氣侵入到泵內(nèi)部的裝置或措施稱為密封，被密封的介質(zhì)一般為液體、氣體或粉塵。泵的密封裝置主要分兩類：一類為靜密封，一類為動(dòng)密封。靜密封通常有墊片密封、O型圈密封、螺紋密封等型式。動(dòng)密封則主要有軟填料密封、油封密封、迷宮密封、螺旋密封、動(dòng)力密封和機(jī)械密封等。造成泄漏的原因主要有兩個(gè)方面：一是密封面上有間隙。二是密封部位兩側(cè)存在壓力差，消除或減小任何一個(gè)因素都可以阻止或減小泄漏，達(dá)到密封的目的。泵的設(shè)計(jì)壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內(nèi)部的間隙。機(jī)械密封機(jī)械密封是現(xiàn)代泵軸封的主要方法，雖然利用它實(shí)現(xiàn)完全不泄漏不大容易，但是達(dá)到微小的，令人完全可以接受的泄漏量卻是完全可能的。但在泵的運(yùn)行中卻經(jīng)常出現(xiàn)令人尷尬的局面，那么機(jī)械密封失效的原因是什么呢?1、械密封的材質(zhì)選擇不合適。機(jī)械密封的材質(zhì)與所輸送的介質(zhì)不相匹配。在工作時(shí)，密封元件很快被腐蝕，溶解或磨損，因而失去密封能力。所以根據(jù)輸送介質(zhì)的性質(zhì)而選擇機(jī)械密封的材質(zhì)是保證其密封功能和正常壽命的先決條件。山西格蘭富機(jī)械密封件。</p><div

如油渣泵、回?zé)捰捅?、常減壓塔底泵等常見(jiàn)的失效現(xiàn)象。在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)進(jìn)入密封面、抽空等情況下，都會(huì)導(dǎo)致環(huán)面出現(xiàn)徑向裂紋；b）石墨炭化是使用碳-石墨環(huán)時(shí)密封失效的主要原因之一。由于在使用中，如果石墨環(huán)一旦超過(guò)許用溫度（一般在-105～250℃）時(shí)，其表面會(huì)析出樹(shù)脂，摩擦面附近樹(shù)脂會(huì)發(fā)生炭化，當(dāng)有粘結(jié)劑時(shí)，會(huì)發(fā)泡軟化，使密封面泄漏增加，密封失效；c）輔助密封件（如氟橡膠、乙丙橡膠、全橡膠）在超過(guò)許用溫度后，將會(huì)迅速老化、龜裂、變硬失彈?，F(xiàn)在所使用的柔性石墨耐高溫、耐腐蝕性較好，但其回彈性差。而且易脆裂，安裝時(shí)容易損壞。6、由于密封端面的磨損而造成的密封失效a）摩擦副所用的材料耐磨性差、摩擦系數(shù)大、端面比壓（包括彈簧比壓）過(guò)大等,都會(huì)縮短機(jī)械密封的使用壽命。對(duì)常用的材料，按耐磨性排列的次序?yàn)椋禾蓟?碳石墨、硬質(zhì)合金-碳石墨、陶瓷-碳石墨、噴涂陶瓷--碳石墨、氮化硅陶瓷--碳石墨、高速鋼--碳石墨、堆焊硬質(zhì)合金--碳石墨。b）對(duì)于含有固體顆粒介質(zhì)，密封面進(jìn)入固體顆粒是導(dǎo)致使密封失效的主要原因。固體顆粒進(jìn)入摩擦副端面起研磨劑作用，使密封發(fā)生劇烈磨損而失效。密封面合理的間隙。沈陽(yáng)格蘭富機(jī)械密封件。福州CL40101-533221
