國產(chǎn)碳化鎢硬質(zhì)合金的物理—力學(xué)性機(jī)械密封對輔助密封圈材料的要求：1）材料彈性好，特別是要求良好的復(fù)原性，變形要小；2）不受流體介質(zhì)的侵蝕，而且在介質(zhì)中的膨脹和收縮都不大；3）摩擦因數(shù)小和耐磨性好；4）使用溫度范圍要廣，在高、低溫下不粘著、不變硬、脆和失彈；5）要有適當(dāng)?shù)牧W(xué)性能，如扯斷強(qiáng)度及其延伸率、耐壓等，在壓力作用下無顯著變形，有優(yōu)良的抗撕裂性、耐磨性和耐壓性等；6）便于加工并可得到高的精度；7）抗介質(zhì)腐蝕、溶解、溶脹、老化等性能好，對介質(zhì)不應(yīng)有污染等。作為輔助密封圈的材料有橡膠、塑料、石棉、膨脹石墨、石墨和金屬脹圈等。橡膠圈是使用廣的一種輔助密封圈。常用的橡膠密封圈材料有丁腈橡膠、氟橡膠、硅橡膠、氯丁橡膠、丁苯橡膠等。丁腈橡膠是常用的一種耐油橡膠。它是丁二烯和丙烯腈的共聚物。根據(jù)丙烯腈含量多少分成若干種：低丙烯腈（丁腈-18）、中丙烯腈（丁腈-26）和高丙烯腈（丁腈-40）、丙烯腈含量越高，它的耐油性越好，抗張強(qiáng)度、硬度和耐磨性、耐水性增加，透氣性減小。隨之而來，它在極性溶劑中是溶解度卻增大，耐腐蝕性也受到影響，彈性和耐寒性也變差。丁腈橡膠不耐撓曲，抗撕裂也較差。齊齊哈爾反應(yīng)釜機(jī)械密封件虎丘區(qū)109機(jī)械密封件。</p><div

2.故障二：真空狀態(tài)運行造成的機(jī)械密封滲漏產(chǎn)生原因：泵在起動、停機(jī)過程中,由于泵進(jìn)口堵塞，抽送介質(zhì)中含有氣體等原因，有可能使密封腔出現(xiàn)負(fù)壓，密封腔內(nèi)若是負(fù)壓，會引起密封端面干摩擦，內(nèi)裝式機(jī)械密封會產(chǎn)生漏氣(水)現(xiàn)象。解決方法：裝配采用雙端面機(jī)械密封，這樣有助于改善潤滑條件，提高密封性能。（二）由于介質(zhì)引起的滲漏1.故障一：靜環(huán)和動環(huán)的輔助密封件無彈性或者有的已經(jīng)腐爛，造成了機(jī)封的大量滲漏甚至有磨軸的現(xiàn)象。產(chǎn)生原因：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。解決方法：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.故障二：真空固體顆粒雜質(zhì)引起的機(jī)械密封滲漏產(chǎn)生原因：固體顆粒進(jìn)入密封端面,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)。解決方法：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。張家港109-20機(jī)械密封件。</p><div

防止將工具、多余零件密封在箱殼之中造成事故。（三）裝配工作中的密封性在機(jī)械使用中，由于密封失效，常常出現(xiàn)"三漏"（漏油、漏水、漏氣）現(xiàn)象。這種現(xiàn)象輕則造成能量損失，以至降低或喪失工作能力，造成環(huán)境污染，重則可能造成嚴(yán)重事故。因此，防止"三漏"極為重要。流體漏損的原因可能由于密封裝置的裝配工藝不符合要求，也可能是由于密封件被磨損、變形、老化、腐蝕所至，而后者也往往與裝配因素（包括選用密封件材料、預(yù)緊程度、裝配位置等）有關(guān)。為此，在裝配工作中必須給以足夠的重視。1、選用密封材料要恰當(dāng)一般要根據(jù)不同的壓力、溫度、介質(zhì)選用。紙質(zhì)墊片只用于低壓、低溫條件；橡膠耐壓、耐溫能力也不高，且要考慮各種橡膠的不同性能，如耐油、耐酸、耐堿等；塑料的耐壓能力較好，但也不耐高溫；石棉強(qiáng)度較低，卻能耐高溫；金屬則兼有耐高溫、高壓的能力。2、合理裝配.要有合適的裝配緊度，并且壓緊要均勻。當(dāng)壓緊度不足時，會引起泄漏，或者在工作一段時間后，由于振動及緊定螺釘被拉長而喪失緊度，導(dǎo)致泄漏；壓緊度過緊，對靜密封的墊片來講，會喪失彈力，引起墊片早期失效；對動密封來講，會引起發(fā)熱、加速磨損、增大摩擦功率等不良后果。臨西機(jī)械密封件選型</p><p
