***節(jié)機(jī)械密封原理機(jī)械密封是一種旋轉(zhuǎn)機(jī)械的軸封裝置。比如離心泵、離心機(jī)、反應(yīng)釜和壓縮機(jī)等設(shè)備。由于傳動(dòng)軸貫穿在設(shè)備內(nèi)外，這樣，軸與設(shè)備之間存在一個(gè)圓周間隙，設(shè)備中的介質(zhì)通過該間隙向外泄漏，如果設(shè)備內(nèi)壓力低于大氣壓，則空氣向設(shè)備內(nèi)泄漏，因此必須有一個(gè)阻止泄漏的軸封裝置。軸封的種類很多，由于機(jī)械密封具有泄漏量少和壽命長(zhǎng)等優(yōu)點(diǎn)，所以當(dāng)今世界上機(jī)械密封是這些設(shè)備主要的軸密封方式。機(jī)械密封又叫端面密封，在國(guó)家有關(guān)標(biāo)準(zhǔn)中是這樣定義的：“由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置?！币弧C(jī)械密封的分類機(jī)械密封近年來發(fā)展很快，根據(jù)不同的工況出現(xiàn)了各種各樣的結(jié)構(gòu)，但無論哪種結(jié)構(gòu)都由以下四部分組成：一部分是由動(dòng)環(huán)和靜環(huán)組成的密封端面，有時(shí)也稱為摩擦副。第二部分是由彈性元件為主要零件組成的緩沖補(bǔ)償機(jī)構(gòu)，其作用是使密封端面緊密貼合。第三部分是輔助密封圈，其中有動(dòng)環(huán)和靜環(huán)密封圈。第四部分是使動(dòng)環(huán)隨軸旋轉(zhuǎn)的傳動(dòng)機(jī)構(gòu)。機(jī)械密封實(shí)現(xiàn)的原理如圖所示：軸通過傳動(dòng)座（6）和推環(huán)（4），帶動(dòng)動(dòng)環(huán)（2）旋轉(zhuǎn)，靜環(huán)(1)固定不動(dòng)。</p><p> 專門進(jìn)行詳細(xì)介紹。四、機(jī)械密封泄漏的原因分析新安裝(或更換)的機(jī)械密封投入運(yùn)轉(zhuǎn)時(shí)泄漏量應(yīng)在允許范圍內(nèi)。如果密封本身的結(jié)構(gòu)、制造質(zhì)量、安裝和使用等方面都無問題，其壽命要超過8000h。實(shí)際工作中，不少密封的使用壽命遠(yuǎn)沒有達(dá)到該值前就失效了，這是由于工藝條件、設(shè)備運(yùn)行狀況和操作存在一定的問題造成的。根據(jù)近幾年來機(jī)械密封運(yùn)行工況和失效后的拆檢情況來看，其常見原因如下：1、密封環(huán)熱裂紋機(jī)械密封拆開時(shí)可發(fā)現(xiàn)，硬環(huán)表面有過熱回火色，石墨環(huán)表面有環(huán)狀溝紋、橡膠圈老化等。主要原因是：①由于介質(zhì)溫度過高泵體內(nèi)形成汽蝕，汽蝕發(fā)生后，水力沖擊帶動(dòng)密封做迅速的軸向振蕩，使動(dòng)靜環(huán)及輔助密封圈等零件嚴(yán)重的磨損，使機(jī)械密封裝置損壞。②潤(rùn)滑不良，密封環(huán)端面沒有形成液體潤(rùn)滑膜或密封環(huán)端面間液膜汽化，形成干摩擦；③冷卻系統(tǒng)散熱不良；2、離心泵的振動(dòng)由于制造和安裝精度等原因，所有的離心泵都存在著振動(dòng)。振動(dòng)的原因主要為轉(zhuǎn)子不平衡、機(jī)泵不同心、滾動(dòng)軸承故障等。從軸承箱表面測(cè)到的大振幅不能大于，超過該值就要停泵處理。振動(dòng)可分解為三個(gè)方向：垂直、水平和軸向，其中以軸向振動(dòng)對(duì)密封的危害大。當(dāng)泵振動(dòng)加劇時(shí)，動(dòng)靜環(huán)之間發(fā)生分離。天水循環(huán)泵用機(jī)械密封選型。</p><div

一般選用耐老化性能較好的丁晴橡膠。當(dāng)輸送介質(zhì)在-50～200℃時(shí)，選用氟橡膠更為合適。因?yàn)樗四陀湍蜔嵬?，機(jī)械強(qiáng)度大也是其主要特征。在化工泵中，由于所輸送介質(zhì)具有腐蝕性，所以一般選用聚四氟乙烯做為墊片材料。隨著泵使用的領(lǐng)域越來越***，所輸送介質(zhì)種類也越來越多，因此在選用墊片材質(zhì)時(shí)應(yīng)查閱相關(guān)資料或通過實(shí)驗(yàn)后再做出正確選擇。墊片失效的原因主要有下列幾種情況：1、墊片材質(zhì)內(nèi)部組織或厚度不均勻，以及使用了帶有裂縫或折皺的紙板，使墊片本身形成了間隙，當(dāng)作用在墊片上的力使墊片所產(chǎn)生的彈性變形不足以完全填充這些間隙時(shí)，泄漏也就不可避免了。2、墊片的材質(zhì)與所輸送的介質(zhì)不相適應(yīng)。由于泵所輸送化工產(chǎn)品化學(xué)性質(zhì)的多樣性，以及為提高燃油的燃燒值或改變其燃燒后的生成物而在燃油中增加入了一些少量的添加劑后而使燃油的某些性質(zhì)發(fā)生變化，所以選擇和輸送介質(zhì)相適的墊片材質(zhì)并非易事，因而也經(jīng)常發(fā)生由于不相適應(yīng)而使墊片發(fā)生侵蝕而產(chǎn)生泄漏的現(xiàn)象。3、作用在密封墊片上的壓力不足。由于密封面上總是存在著微觀的凹凸不平，有時(shí)還在密封面上加工出若干環(huán)形溝槽，若保證密封，就必須對(duì)密封墊片施加足夠大的壓力，使其發(fā)生彈性或塑性變形以填充這些間隙。貴州福斯泵用機(jī)械密封泄露。甘肅泵用機(jī)械密封尺寸</p><p

在國(guó)產(chǎn)離心泵上得到了***的應(yīng)用。本教材以這兩種國(guó)產(chǎn)機(jī)械密封為主，結(jié)合其它結(jié)構(gòu)型式（包括進(jìn)口的密封），就有關(guān)的技術(shù)問題和故障分析。第二節(jié)機(jī)械密封的基本元件密封環(huán)是動(dòng)環(huán)和靜環(huán)的總稱（下同），是構(gòu)成機(jī)械密封**主要的元件。一、密封環(huán)在很大程度上決定了機(jī)械密封的使用性能和壽命，對(duì)它提出了一些要求。1）有足夠的強(qiáng)度和剛度。在工作條件下（如壓力、溫度和滑動(dòng)速度等）不損壞，變形應(yīng)盡量的小，工作條件波動(dòng)時(shí)仍能保持密封性。2）密封端面應(yīng)有足夠的硬度和耐腐蝕性，以保證工作條件下有滿意的使用壽命。3）密封環(huán)應(yīng)有良好的耐熱沖擊能力。為此，要求材料有較高的導(dǎo)熱系數(shù)和較小的線膨脹系數(shù)，承受熱沖擊時(shí)不至于開裂。4）密封環(huán)匹配應(yīng)有較小的摩擦系數(shù)和良好的自潤(rùn)滑性，密封環(huán)材料與密封流體還要有很好的浸潤(rùn)性。工作中如發(fā)生短時(shí)間的干摩擦，不損傷密封端面。5）密封環(huán)應(yīng)力求簡(jiǎn)單、對(duì)稱并優(yōu)先考慮用整體型結(jié)構(gòu)。也可采用組合式（如鑲裝式）密封環(huán)，盡量避免用密封端面噴涂式結(jié)構(gòu)。6）密封環(huán)要容易加工制造，安裝和維修要方便，價(jià)格要低廉。二、摩擦副匹配要考慮的因素摩擦副一般都選擇一軟一硬的配對(duì)。目前軟環(huán)多選用破一石墨（以下簡(jiǎn)稱石墨）。嵐山區(qū)增壓泵用機(jī)械密封</p><p
