***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，三門峽M461釜用機(jī)械密封件、離心機(jī)、反應(yīng)釜和壓縮機(jī)等設(shè)備。由于傳動軸貫穿在設(shè)備內(nèi)外，這樣，軸與設(shè)備之間存在一個圓周間隙，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等優(yōu)點，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，在國家有關(guān)標(biāo)準(zhǔn)中是這樣定義的：“由至少一對垂直于旋轉(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滑動而構(gòu)成的防止流體泄漏的裝置。”一、機(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：一部分是由動環(huán)和靜環(huán)組成的密封端面，有時也稱為摩擦副。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，其中有動環(huán)和靜環(huán)密封圈。第四部分是使動環(huán)隨軸旋轉(zhuǎn)的傳動機(jī)構(gòu)。機(jī)械密封實現(xiàn)的原理如圖所示：軸通過傳動座（6）和推環(huán)（4），三門峽M461釜用機(jī)械密封件，帶動動環(huán)（2）旋轉(zhuǎn)，三門峽M461釜用機(jī)械密封件，靜環(huán)(1)固定不動。德州212釜用機(jī)械密封件。三門峽M461釜用機(jī)械密封件</p><div

釜用機(jī)械密封是解決攪拌軸密封的一種理想方式，按照密封面的對數(shù)，有單端面和雙端面機(jī)械密封之分。雙端面機(jī)械密封一般配上平衡循環(huán)系統(tǒng)，可使用在易燃、易爆、有毒及腐蝕、高真空等對密封要求更為嚴(yán)格的場合。機(jī)械密封的輔助裝置有調(diào)溫器、平衡罐(隔離流體容器)、強(qiáng)制循環(huán)平衡系統(tǒng)等。一、205型機(jī)械密封1、結(jié)構(gòu)特點反應(yīng)釜用205型機(jī)械密封為雙端面、多彈簧、、外流、傳動套傳動的釜用機(jī)械密封，采用非平衡型結(jié)構(gòu)。主要靠密封腔內(nèi)密封液與被密封介質(zhì)間的壓力差達(dá)到密封的目的，密封液另需一套裝置來循環(huán)，整個系統(tǒng)比較復(fù)雜。故*用于密封易燃易爆，有毒及較強(qiáng)腐蝕介質(zhì)的特殊場合。2、適用范圍被密封介質(zhì)：易燃、易爆有毒及較強(qiáng)腐蝕性介質(zhì)。密封腔壓力：P1≤被密封介質(zhì)壓力：P2=()Mpa密封腔溫度：-40℃~250℃線速度：≤20m/s二、206型機(jī)械密封1、結(jié)構(gòu)特點反應(yīng)釜用206型機(jī)械密封為雙端面、多彈簧、外流、傳動套傳動的釜用機(jī)械密封。206系大氣端平衡型結(jié)構(gòu)。其密封作用主要靠密封腔內(nèi)的密封液與介質(zhì)間的壓力差來達(dá)到。由于密封液的循環(huán)需另設(shè)一套循環(huán)裝置，故增加了系統(tǒng)的復(fù)雜性。所以只用于密封易燃、易爆、有毒及較強(qiáng)腐蝕性介質(zhì)對密封要求極嚴(yán)的特殊場合。咸寧高溫釜用機(jī)械密封鶴壁2009釜用機(jī)械密封件。</p><div

要將軸封部分的溫度設(shè)計為0℃，這時用作氣體密封，密封圈可用普通O形或V形密封圈。密封結(jié)構(gòu)是與泵體結(jié)構(gòu)相適應(yīng)，常用的低溫泵采用立式結(jié)構(gòu).3.輔助裝置(1)要盡可能加大沖洗量，加強(qiáng)冷卻措施，或提高密封腔內(nèi)壓力，來控制液溫升高所引起的氣化現(xiàn)象，要***避免從泵出口端裝沖洗管線來沖洗密封端面，因為在低溫下，這種沖洗管線內(nèi)液體會氣化.所以，一般采逆流沖洗方式.(2)防止單端面密封在泵停轉(zhuǎn)過程中大氣中水分與密封接觸使邊緣結(jié)冰，可用甲醇等化冰劑加以溶解，阻封部分也可通人氮氣干氣加以保護(hù).總之，既要充分冷卻又要采取保冷措施。(3)在高于密封面的部位裝設(shè)排氣管線，這樣，如果產(chǎn)生氣體也可從排氣管線逸出。有關(guān)低溫泵的輔助裝置見第七章一節(jié)低溫泵輔助系統(tǒng)。二、低溫甲烷泵機(jī)械密封低溫泵通常是立式結(jié)構(gòu)，密封腔設(shè)在泵的上部，密封結(jié)構(gòu)為雙端面平衡型機(jī)械密封。低溫泵的結(jié)構(gòu)及布置如圖10-19所示。1.低溫泵的結(jié)構(gòu)特點(1)筒形結(jié)構(gòu)，不必?fù)?dān)心低溫時發(fā)生變形.(2)一級葉輪位于底部，通過增減柱形筒體的長度(圖10-19中的葉輪只列出二級，實際有十多級)，.來適應(yīng)葉輪級數(shù)的變化。(3)液體從上向下進(jìn)人葉輪，由吸人端排氣從而起到有效的氣體分離器作用。(4)立式結(jié)構(gòu)排氣順暢。</p><p> 還與軸徑尺寸有關(guān).當(dāng)摩擦副環(huán)基體為不銹鋼、高鎳合金、欽合金時，熱鑲硬質(zhì)合金的允許使用溫度對不同軸徑的關(guān)系如圖10-9所示.5.摩擦副環(huán)與軸之間的許用間隙高溫條件下，由于摩擦副環(huán)與軸兩者的熱脹系數(shù)的差異，會出現(xiàn)摩擦副環(huán)與軸之間間隙趨近于零的現(xiàn)象，因而造成摩擦副環(huán)浮動性消失導(dǎo)致密封失效。所以在設(shè)計時必須合理和正確選擇摩擦副環(huán)與軸之間的間隙。二、高溫機(jī)械密封實例1.布格曼公司的HSHF+MFL型密封芳烴裝置循環(huán)油泵GA-102AB.功率1650kW，轉(zhuǎn)速6748r/min,輸送介質(zhì)為汽油，操作溫度262~284度，進(jìn)口壓力，出口壓力~175MPa，機(jī)械密封采用布格曼公司HSHF+MFL混合結(jié)構(gòu)，這是適合高溫、高壓和高速工作條件下的密封。這里HSHF是單端面、流體動壓式帶泵效螺旋結(jié)構(gòu)MFL是單端面金屬波紋管結(jié)構(gòu).HSHF和MFL都是彈簧靜止式，以適應(yīng)高速運轉(zhuǎn)的要求.該密封從結(jié)構(gòu)上布置成串聯(lián)式，裝于油泵的吸人端和排出端，因HSHF帶有泵效螺旋，它與軸的旋轉(zhuǎn)方向有關(guān).在吸入端的泵效套(12A)是右螺旋，泵效外殼(25A)提左螺旋;在排出端的泵效套(12B)是左螺旋，泵效外殼(25B)是右螺旋，安裝時按圖上要求裝配不能搞錯.，圖10-10為HSHF2/103+MFL65/88的結(jié)構(gòu)圖.。蕪湖204B釜用機(jī)械密封件。</p><div
