或者是由于定位螺釘?shù)乃蓜?、壓蓋沒有壓緊以及機器設(shè)備精度不夠高，使密封面之間沒有完全貼合，都會造成機械密封失效，介質(zhì)泄漏。如果是軸套發(fā)生泄漏，原因可能是軸套密封圈裝配時壓縮量不夠或未被壓緊，也有可能是裝置已經(jīng)損壞。2周期性泄漏機械密封組成部件中轉(zhuǎn)子組件的周期性轉(zhuǎn)動以及軸向移動量過大都會在成機械密封的泄露，機械密封的密封面要受到一定的應力作用才能起到良好的密封作用。要做到以上要求，機械密封的彈簧裝置必須有一定的壓縮量才能給端面一定的應力作用，使機械密封達到預期的密封效果。同時為了保證應力處于適當范圍，泵軸不能有較大的移動量，但是實際設(shè)計中往往出現(xiàn)不合理的因素，使得泵軸的移動量高于預期，這對機械密封的性能具有很大程度的不利影響。3機械密封經(jīng)常性泄露由密封端面的損傷引起的經(jīng)常性泄漏故障表現(xiàn)有機械密封石墨端面出現(xiàn)均勻環(huán)狀溝紋、石墨斷面處產(chǎn)生的環(huán)狀深溝、石墨內(nèi)部邊緣的磨損、石墨環(huán)臺階被磨損、石墨外邊援缺口、石墨環(huán)斷裂、石墨環(huán)上出現(xiàn)腐蝕坑、硬質(zhì)合金面裂痕以及灼傷等。輔助密封圈引起的經(jīng)常性泄漏故障表現(xiàn)有端面磨損、鑲嵌環(huán)松脫等。彈簧引起的泄漏包括轉(zhuǎn)子振動、零件松動、介質(zhì)問題以及機械密封輔助設(shè)置的損壞等。安徽離心泵機械密封件2機械密封常用材料的選用凈水;</p><div

機械密封用碳石墨材料大致分為如下幾類：1.焙燒石墨，從某種意義上來講，焙燒石墨分為硬質(zhì)碳石墨和軟質(zhì)電化石墨。它們由石油炭黑、油煙炭黑在其內(nèi)摻和焦油、瀝青等混合，經(jīng)粉碎壓制成素坯，置于高溫中焙燒而成。兩者除材料的組分不一樣外，主要區(qū)別是后者需經(jīng)2400～2800攝氏度的高溫石墨化處理。石墨在焙燒時，由于粘結(jié)劑中揮發(fā)物質(zhì)產(chǎn)生揮發(fā)以及粘結(jié)劑的聚合、分解和碳化，從而出現(xiàn)孔隙(有10%～30%的氣孔)。用作密封環(huán)會出現(xiàn)滲透性泄漏，而且強度低，因此要進行浸漬處理以補隙增強，即經(jīng)過浸漬處理后成為不透氣性制品，強度也得以提高。但耐溫和耐腐蝕性能都有不同程度的下降。所用浸漬物有三大類：有機樹脂、無機物和金屬。2.樹脂結(jié)合石墨，它是將燒結(jié)后的石墨粉碎，以酚醛樹脂或環(huán)氧樹脂等作粘結(jié)劑，混合后經(jīng)壓制燒結(jié)成制品。基體中的樹脂燒結(jié)后成為碳粒，因此是不透氣性能石墨。它的導熱性較差，線膨脹系數(shù)大；適用于大批量生產(chǎn)，成本低廉；主要用于汽車冷卻水泵、家用電器等低負荷的密封。3.熱解石墨，國產(chǎn)熱解石墨是用丙烯等碳氫化合物在高溫下經(jīng)熱解，使碳蒸汽滲透到碳石墨坯體的氣孔中，起堵孔作用，形成高密、少孔、低透氣性的純碳石墨材料。其氣孔率<1%。</p><p> 氟橡膠具有耐高溫、耐油、耐化學腐蝕的優(yōu)點。氟橡膠中應用廣的是含氟烯烴共聚物，主要是26型和23型。26型中有氟橡膠-26系偏氟橡乙烯與六氟丙烯的乳液共聚物和氟橡膠-246系偏氟乙烯、六氟丙烯與四氟丙烯的三元共聚物。23型氟橡膠由偏氟乙烯與三氟氯乙烯在室溫及。它不能用于液氨、氨水中。硅橡膠是由二甲基硅氧烷與其他有機硅單體在酸或堿性催化劑存在下聚合成的一種極性高分子聚合物。硅橡膠有很高的熱穩(wěn)定性，但它有極性，容易在酸堿作用下發(fā)生離子型裂解，因此耐腐蝕性差，不適宜用于石油系溶劑（如苯、甲苯等）、丙酮、酮醚等有機溶劑。聚四氟乙烯具有優(yōu)異的化學穩(wěn)定性和耐油、耐溶劑、抗老化、耐溫性能，并有相當?shù)偷哪Σ烈驍?shù)和一定的強度、彈性、柔性和不粘著性，因此***用作各種溫度、壓力、腐蝕性介質(zhì)條件下的密封圈。綜上所述，輔助密封材料，在一般介質(zhì)中可使用橡膠材料制成的O形圈、墊圈和波紋管等；在腐蝕性介質(zhì)中可使用聚四氟乙烯制成的V形圈、楔形環(huán)、墊圈和波紋管等；在高、低溫條件下可使用金屬波紋管。選用時應考慮材料的使用溫度和耐腐蝕性。機械密封輔助密封材料列表機械密封主要零件材料選擇機械密封各主要零件的材料應根據(jù)使用工況進行選擇，見下表。蘇州波紋管機械密封件。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽離心泵機械密封件,機械密封件" src="https://tyunfile.71360.com/UploadFile/ygebgm/637324159214443360/2833392.png"></div><p> 對策：采用雙端面機械密封，這樣有助于改善潤滑條件，提高密封性能。3、由于介質(zhì)引起的滲漏（1）大多數(shù)潛污泵機械密封拆解后，靜環(huán)和動環(huán)的輔助密封件無彈性，有的已經(jīng)腐爛，造成了機封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對靜環(huán)和動環(huán)輔助橡膠密封件的腐蝕作用，造成了機械滲漏過大，動、靜環(huán)橡膠密封圈材料為丁腈—40，不耐高溫，不耐酸堿，當污水為酸性堿性時易腐蝕。對策：對腐蝕性介質(zhì)，橡膠件應選用耐高溫、耐弱酸、弱堿的氟橡膠。（2）固體顆粒雜質(zhì)引起的機械密封滲漏如果固體顆粒進入密封端面，將會劃傷或加快密封端面的磨損，水垢和油污在軸（套）表面的堆積速度超過摩擦副的磨損速度，致使動環(huán)不能補償磨耗位移，硬對硬摩擦副的運轉(zhuǎn)壽命要比硬對石墨摩擦副的長，因為固體顆粒會嵌入石墨密封環(huán)的密封面內(nèi)。對策：在固體顆粒容易進入的位置應選用碳化鎢對碳化鎢摩擦副的機械密封。4、因其他問題引起的機械密封滲漏機械密封中還存在設(shè)計、選擇、安裝等不夠合理的地方。（1）彈簧壓縮量一定要按規(guī)定進行，不允許有過大或過小的現(xiàn)象，誤差±2mm，壓縮量過大增加端面比壓，摩擦熱量過多，造成密封面熱變形和加速端面磨損。常熟水泵機械密封件。安徽離心泵機械密封件</p><p
