機(jī)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(qiáng)度低，因此要進(jìn)行浸漬處理以補(bǔ)隙增強(qiáng)，即經(jīng)過浸漬處理后成為不透氣性制品，強(qiáng)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(jī)樹脂、無機(jī)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?；w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(dǎo)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?yán)鋮s水泵、家用電器等低負(fù)荷的密封。3.熱解石墨，國產(chǎn)熱解石墨是用丙烯等碳?xì)浠衔镌诟邷叵陆?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%。廣西機(jī)械密封件廠高新區(qū)波紋管機(jī)械密封件。</p><div

1機(jī)械密封的工作原理機(jī)械密封是靠一對或數(shù)對垂直于軸作相對滑動的端面在流體壓力和補(bǔ)償機(jī)構(gòu)的彈力(或磁力)作用下保持貼合并配以輔助密封而達(dá)到阻漏的軸封裝置。2機(jī)械密封常用材料的選用凈水;常溫;(動)9CR18，1CR13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂石墨，青銅，酚醛塑料。河水(含泥沙);常溫;(動)碳化鎢，(靜)碳化鎢海水;常溫;(動)碳化鎢，1CR13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂石墨，碳化鎢，金屬陶瓷;過熱水100度;(動)碳化鎢，1CR13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂石墨，碳化鎢，金屬陶瓷;汽油，潤滑油，液態(tài)烴;常溫;(動)碳化鎢，1CR13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂或錫銻合金石墨，酚醛塑料。汽油，潤滑油，液態(tài)烴;100度;(動)碳化鎢，1CR13堆焊鈷鉻鎢;(靜)浸青銅或樹脂石墨。汽油，潤滑油，液態(tài)烴;含顆粒;(動)碳化鎢;(靜)碳化鎢。3密封材料的種類及用途密封材料應(yīng)知足密封功能的要求。因為被密封的介質(zhì)不同，以及設(shè)備的工作前提不同，要求密封材料的具有不同的適應(yīng)性。對密封材料的要求一般是：1)材料致密性好，不易泄露介質(zhì);2)有適當(dāng)?shù)臋C(jī)械強(qiáng)度和硬度;3)壓縮性和回彈性好，變形小;4)高溫下不軟化，不分解，低溫下不硬化，不脆裂;5)抗侵蝕機(jī)能好，在酸，堿，油等介質(zhì)中能長期工作。</p><p> 對策：采用雙端面機(jī)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(jī)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(jī)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(jī)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(dāng)污水為酸性堿性時易腐蝕。對策：對腐蝕性介質(zhì)，橡膠件應(yīng)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(jī)械密封滲漏如果固體顆粒進(jìn)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(bǔ)償磨耗位移，硬對硬摩擦副的運(yùn)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(jìn)入的位置應(yīng)選用碳化鎢對碳化鎢摩擦副的機(jī)械密封。4、因其他問題引起的機(jī)械密封滲漏機(jī)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(jìn)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。張家港橡膠波紋管機(jī)械密封件。</p><div

2非金屬環(huán)腐蝕石墨環(huán)被腐蝕也是機(jī)械密封是小的重要原因之一，斷面溫度過高、浸漬樹脂選擇不當(dāng)、浸漬樹脂深度不夠等都是導(dǎo)致石墨環(huán)被腐蝕的原因。當(dāng)石墨環(huán)處于氧化性介質(zhì)中時，出冷卻不良或產(chǎn)生摩擦?xí)r，環(huán)境產(chǎn)生三四百度會促使石墨與氧化性介質(zhì)發(fā)生氧化反應(yīng)，使端面變得失去性能。3輔助密封圈及接觸部位的腐蝕不同的材料有不同的抗腐蝕性，輔助密封圈的材料一般選取具有彈性的橡膠，而橡膠被腐蝕后會使表面變得異常粗糙，失去原有的彈性。并且橡膠的耐高溫性能比較差，一般不超過兩百度。與輔助密封圈相接觸的部位處于相對靜止的狀態(tài)，二者之間的縫隙以及摩擦等都會是腐蝕產(chǎn)生的原因，并且腐蝕面一般較寬、較深。機(jī)泵機(jī)械密封的故障表現(xiàn)生產(chǎn)過程中，機(jī)泵機(jī)械密封泄露的原因有其本身的原因及外部原因，材料的選擇以及安裝方式和使用方式都會引起機(jī)械密封的失效，失效時的故障表現(xiàn)也各有差異，學(xué)會通過不同故障表現(xiàn)并做出正確及時的判斷能夠?qū)嶋H生產(chǎn)提供強(qiáng)有力的支持。1靜壓實驗時泄露機(jī)械密封裝置在安裝時由于員工不細(xì)心，經(jīng)常會使密封端面被碰傷以至于變形和損壞，清理不夠徹底，使得機(jī)械密封夾有顆粒狀雜質(zhì)。廣西機(jī)械密封件廠</p><p
