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??；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。張家港泵用機(jī)械密封件。遼寧109-25機(jī)械密封件</p><p

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(shí)，會(huì)引起泄漏，或者在工作一段時(shí)間后，由于振動(dòng)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(huì)喪失彈力，引起墊片早期失效；對動(dòng)密封來講，會(huì)引起發(fā)熱、加速磨損、增大摩擦功率等不良后果。遼寧109-25機(jī)械密封件</p></p><br
