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)械密封件會發(fā)生表面腐蝕，嚴(yán)重時也可發(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.點腐蝕彈簧套常出現(xiàn)大面積點蝕或區(qū)域性點蝕，有的導(dǎo)致穿孔，此類局部腐蝕對密封使用尚不會造成很嚴(yán)重的后果，不過大修時也應(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，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> 各種墊片材質(zhì)的壓緊力大小通常在密封墊片生產(chǎn)廠家樣本或產(chǎn)品說明書中給出，也可通過實驗決定。由于裝配時達(dá)不到墊片所需的壓緊力或由于在常期運行中的振動使壓緊螺栓松動而使壓緊力降低以及由于墊片材質(zhì)的老化變形而喪失原來的彈性都會使墊片失效而產(chǎn)生泄漏。O型圈密封泵中常用的是橡膠O型圈。由于其形狀十分簡單，因而制造容易，成本低廉，不論O型圈的整體尺寸有多大，其截面尺寸都很小(只有幾毫米)所以重量輕，消耗材料少，使用方法簡單，安裝、拆卸方便，更為突出的優(yōu)點還在于O形圈具有良好的密封能力，使用范圍很寬。靜密封工作壓力可達(dá)100MPa以上，動密封也可達(dá)30Mpa。適用溫度為-60～200℃，可滿足多種介質(zhì)的使用要求。因此在泵的設(shè)計中得到越來越廣的應(yīng)用。O形密封圈安裝在溝槽和被密封面之間，有一定壓縮量，由此產(chǎn)生的反彈力給予被密封的光滑面和溝槽底面以初始的壓縮應(yīng)力。從而起到密封作用。當(dāng)被密封的液體壓力增大時，O形圈的變形也隨之增大，從而傳遞給密封面的壓力也增大，密封的作用也增大。這就是O形密封圈具有良好密封能力的原因。O形密封圈雖然密封可靠，但如果不注意使用條件，也會發(fā)生泄漏，通常有以下幾種情況：1、裝O形圈的溝槽尺寸超差。馬鞍山格蘭富機(jī)械密封件。</p><div

通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤滑的作用。然而，在填料盒內(nèi)，采用彈簧負(fù)載和液體壓力相結(jié)合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會影響接觸面之間形成液體薄膜，導(dǎo)致熱量增加和過早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進(jìn)行研磨。然后，采用單色光源的光柵板對其檢測。從這一觀點出發(fā)，對這些密封接觸面必須小心處理，并嚴(yán)格按照安裝說明，保證密封面得到適當(dāng)?shù)谋Ｗo(hù)和正確就位，這一點是非常重要的。密封的靈活性選擇主軸的軸向和徑向運動需要與彈簧之間保持一定的靈活性，以保證接觸面之間的密封。然而，只能提供一定程度的靈活性。液泵的機(jī)械狀況及其長度直徑比(一種主軸的直徑與其延伸長度之比的衡量方式，比值越低越好)對密封的可靠性起著重要的作用。密封的靈活性一般由一個大型主彈簧和一系列小彈簧或波紋密封裝置提供保證。橋東區(qū)格蘭富機(jī)械密封件。江蘇格蘭富機(jī)械密封件CRN20-6</p><p
