一、機(jī)械密封概述機(jī)械密封（端面密封）是一種用來(lái)解決旋轉(zhuǎn)軸與機(jī)體之間密封的裝置。它是由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面的流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用及輔助密封的配合下保持貼合下并相對(duì)滑動(dòng)而構(gòu)成防止流體泄漏的裝置，常用于泵、壓縮機(jī)、反應(yīng)攪拌釜等旋轉(zhuǎn)式流體機(jī)械，也用于齒輪箱、船舶尾軸等密封。因此，機(jī)械密封是一種通用的軸封裝置。機(jī)械密封結(jié)構(gòu)多種多樣，常用的機(jī)械密封結(jié)構(gòu)是端面密封。端面密封的靜環(huán)、動(dòng)環(huán)組成一對(duì)摩擦副，摩擦副的作用是防止介質(zhì)泄漏。它要求靜環(huán)、動(dòng)環(huán)，具有良好的耐磨性，動(dòng)環(huán)可以在軸向靈活的移動(dòng)，自動(dòng)補(bǔ)償密封面磨損，使之與靜環(huán)良好的貼合；靜環(huán)具有浮動(dòng)性，起緩沖作用。為此，密封面要求有良好的加工質(zhì)量，保證密封副有良好的貼合性能。構(gòu)成機(jī)械密封的基本元件有靜環(huán)、動(dòng)環(huán)、壓蓋、推環(huán)、彈簧、定位環(huán)、軸套、動(dòng)環(huán)密封圈、靜環(huán)密封圈軸套密封圈等。彈性元件（彈簧、波紋管）它主要起預(yù)緊、補(bǔ)償和緩沖的作用，要求始終保持足夠的彈性來(lái)克服輔助密封和傳動(dòng)件的摩擦和動(dòng)環(huán)等的慣性，保證端面密封副良好的貼合和動(dòng)環(huán)的追隨性，材料要求耐腐蝕、耐疲勞。輔助密封。</p><p> 如油渣泵、回?zé)捰捅?、常減壓塔底泵等常見(jiàn)的失效現(xiàn)象。在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)進(jìn)入密封面、抽空等情況下，都會(huì)導(dǎo)致環(huán)面出現(xiàn)徑向裂紋；b）石墨炭化是使用碳-石墨環(huán)時(shí)密封失效的主要原因之一。由于在使用中，如果石墨環(huán)一旦超過(guò)許用溫度（一般在-105～250℃）時(shí)，其表面會(huì)析出樹(shù)脂，摩擦面附近樹(shù)脂會(huì)發(fā)生炭化，當(dāng)有粘結(jié)劑時(shí)，會(huì)發(fā)泡軟化，使密封面泄漏增加，密封失效；c）輔助密封件（如氟橡膠、乙丙橡膠、全橡膠）在超過(guò)許用溫度后，將會(huì)迅速老化、龜裂、變硬失彈。現(xiàn)在所使用的柔性石墨耐高溫、耐腐蝕性較好，但其回彈性差。而且易脆裂，安裝時(shí)容易損壞。6、由于密封端面的磨損而造成的密封失效a）摩擦副所用的材料耐磨性差、摩擦系數(shù)大、端面比壓（包括彈簧比壓）過(guò)大等,都會(huì)縮短機(jī)械密封的使用壽命。對(duì)常用的材料，按耐磨性排列的次序?yàn)椋禾蓟?碳石墨、硬質(zhì)合金-碳石墨、陶瓷-碳石墨、噴涂陶瓷--碳石墨、氮化硅陶瓷--碳石墨、高速鋼--碳石墨、堆焊硬質(zhì)合金--碳石墨。b）對(duì)于含有固體顆粒介質(zhì)，密封面進(jìn)入固體顆粒是導(dǎo)致使密封失效的主要原因。固體顆粒進(jìn)入摩擦副端面起研磨劑作用，使密封發(fā)生劇烈磨損而失效。密封面合理的間隙。朝陽(yáng)區(qū)格蘭富機(jī)械密封件。</p><div

機(jī)械密封是利用兩個(gè)平面互相摩擦運(yùn)行的原理，達(dá)到密封的目的。旋轉(zhuǎn)密封面安裝于液泵的主軸上，而固定密封面安裝于密封壓蓋內(nèi)。由于一個(gè)密封面是運(yùn)動(dòng)的，而另一個(gè)密封面是靜止不動(dòng)的，因此將這類(lèi)密封稱(chēng)之為動(dòng)態(tài)密封。圖1旋轉(zhuǎn)面與靜止面之間的密封是決定密封性能關(guān)鍵的因素?；A(chǔ)的機(jī)械密封如圖1所示，其中有4個(gè)泄漏通路需要密封：1.密封面之間的通路;2.旋轉(zhuǎn)面與主軸之間的通路;3.固定面與壓蓋之間的通路;4.壓蓋與填料盒之間的通路。后兩種泄漏通路一般采用靜態(tài)密封，因?yàn)閮刹糠种g不存在相對(duì)運(yùn)動(dòng)。這部分的密封通常都稱(chēng)之為三次密封，其密封材料為墊片或與工藝流程液體相適應(yīng)的O型密封圈。在較老的密封設(shè)計(jì)中，位于旋轉(zhuǎn)面下的二次密封留有一定的間隙，可在主軸上前后運(yùn)動(dòng)，因此易于引起磨損和過(guò)早失效。然而在較新的密封設(shè)計(jì)中，二次密封處于靜止?fàn)顟B(tài)，因此可避免在主軸上出現(xiàn)磨損腐蝕問(wèn)題。在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動(dòng)和停機(jī)時(shí)，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來(lái)代替)。大部分機(jī)械密封的設(shè)計(jì)采用較軟的材料來(lái)制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來(lái)。日照格蘭富機(jī)械密封件。晉城格蘭富機(jī)械密封件CR64-2-1</p><p
