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(zhǎng)而喪失緊度，導(dǎo)致泄漏；壓緊度過緊，曲陽熱水泵機(jī)械密封件，對(duì)靜密封的墊片來講，會(huì)喪失彈力，曲陽熱水泵機(jī)械密封件，引起墊片早期失效；對(duì)動(dòng)密封來講，會(huì)引起發(fā)熱、加速磨損，曲陽熱水泵機(jī)械密封件、增大摩擦功率等不良后果。蘇州109-25機(jī)械密封件。曲陽熱水泵機(jī)械密封件</p><div

把動(dòng)環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤(rùn)滑油量不足引起干摩擦或拉毛密封端面。對(duì)策：油室腔內(nèi)潤(rùn)滑油面高度應(yīng)加到高于動(dòng)、靜環(huán)密封面。（3）轉(zhuǎn)子周期性振動(dòng)。原因是定子與上、下端蓋未對(duì)中或葉輪和主軸不平衡，汽蝕或軸承損壞（磨損），這種情況會(huì)縮短密封壽命和產(chǎn)生滲漏。對(duì)策：可根據(jù)維修標(biāo)準(zhǔn)來糾正上述問題。2、由于壓力產(chǎn)生的滲漏（1）高壓和壓力波造成的機(jī)械密封滲漏由于彈簧比壓力及總比壓設(shè)計(jì)過大和密封腔內(nèi)壓力超過3MPa時(shí)，會(huì)使密封端面比壓過大，液膜難以形成，密封端面磨損嚴(yán)重，發(fā)熱量增多，造成密封面熱變形。對(duì)策：在裝配機(jī)封時(shí)，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，高壓條件下的機(jī)械密封應(yīng)采取措施。為使端面受力合理，盡量減小變形，可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料，并加強(qiáng)冷卻的潤(rùn)滑措施。（2）真空狀態(tài)運(yùn)行造成的機(jī)械密封滲漏泵在起動(dòng)、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(huì)引起密封端面干摩擦，內(nèi)裝式機(jī)械密封會(huì)產(chǎn)生漏氣（水）現(xiàn)象，真空密封與正壓密封的不同點(diǎn)在于密封對(duì)象的方向性差異，而且機(jī)械密封也有其某一方向的適應(yīng)性。曲陽熱水泵機(jī)械密封件常熟波紋管機(jī)械密封件。</p><div

填料密封是靠盤根的壓緊在軸上或軸套上起作用的。填料密封與軸直接摩擦，填料壓的越緊摩擦力就越大、消耗功率也就越大。而機(jī)械密封的摩擦是處于半液摩擦狀態(tài)，摩擦系數(shù)非常的小，機(jī)械密封的功率損失是填料密封的10～50%。（6）波紋管密封軸或軸套不受磨損，對(duì)旋轉(zhuǎn)軸的振擺和軸對(duì)殼體的偏斜不敏感。（7）適用范圍廣。當(dāng)介質(zhì)易燃、易爆、有毒有害時(shí)，采用機(jī)械密封可保證密封。它還適用于高溫、低溫、高壓、真空各種轉(zhuǎn)速的及腐蝕介質(zhì)的設(shè)備密封。2、缺點(diǎn)（1）如結(jié)構(gòu)比填料密封復(fù)雜，加工精度要求高，并要求一定的安裝技術(shù)等，特別是干氣密封的安裝要求更高。而且密封技術(shù)發(fā)展的很快，新技術(shù)不斷出現(xiàn)給我們維修帶來了新的課題。（2）結(jié)構(gòu)復(fù)雜、拆裝不便。與其它密封比較，機(jī)械端面密封的零件數(shù)目多，要求精密，結(jié)構(gòu)復(fù)雜。特別是在裝配方面較困難，拆裝時(shí)要從軸端抽出密封環(huán)，必須把機(jī)器部分（聯(lián)軸器）或全部拆卸。這一問題目前已作了某些改進(jìn)，例如采用拆裝方便并可保證裝配質(zhì)量的剖分式和集裝式機(jī)械密封等。三、機(jī)械密封的工作原理機(jī)械密封亦稱端面密封，是靠一對(duì)或數(shù)對(duì)垂直于軸作相對(duì)滑動(dòng)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。</p><p> 國(guó)產(chǎn)碳化鎢硬質(zhì)合金的物理—力學(xué)性機(jī)械密封對(duì)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(duì)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109-25機(jī)械密封件。</p><div
