氣體不會(huì)在泵的中部滯留·(5)無(wú)軸的彎曲問(wèn)題，軸封可遠(yuǎn)離泵體，減少熱的影響。電機(jī)安裝架為遮風(fēng)結(jié)構(gòu)，所以電機(jī)的溫升對(duì)泵幾乎沒(méi)有影響。(6)泵殼埋于地下，易于保冷.所以，石油液化氣用的低溫泵常用以上這種結(jié)構(gòu).2.低溫甲烷泵機(jī)械密封甲烷液化氣在-99℃時(shí)的蒸汽壓接近3MPa.乙烯裝置脫甲烷塔底泵在-53℃時(shí)出口壓力近似3MPa，采用雙端面串聯(lián)式機(jī)械密封，它是比拉公司BB81-K7+BB81B-S7型，尺寸為45x39與50x45(圖10-20)。耐腐蝕機(jī)械密封在腐蝕性介質(zhì)中，機(jī)械密封的零件受到介質(zhì)的強(qiáng)烈侵蝕，摩擦面同時(shí)受到.腐蝕和磨損，這種現(xiàn)象稱為“磨蝕“，其腐蝕速度約為無(wú)摩擦?xí)r的10~50倍.某些結(jié)構(gòu)材料具有優(yōu)良的耐蝕性能，耐磨性能卻較差;而另一些結(jié)構(gòu)材料雖具有良好的耐磨性，耐蝕性卻很差.因此，摩擦副應(yīng)選擇既要耐腐蝕又要耐磨，輔助密封圈、彈擠和結(jié)構(gòu)件也要有良好的耐蝕性能.在設(shè)計(jì)耐腐蝕機(jī)械密封時(shí)，一般采取以下一些措施:1.結(jié)構(gòu)上的隔離措施采用外裝式結(jié)構(gòu)，經(jīng)過(guò)適當(dāng)?shù)倪x擇，外裝式密封可以做到無(wú)金屬件與工藝介質(zhì)接觸，小的零件如彈簧、銷子可不受工藝介質(zhì)腐蝕.外裝式有普通型機(jī)械密封和波紋管型機(jī)械密封兩種，’以波紋管型密封結(jié)構(gòu)較好(圖10-21).如密封件材質(zhì)耐蝕能力許可。忻州2009釜用機(jī)械密封件哈爾濱207釜用機(jī)械密封件。</p><div

硬環(huán)的材質(zhì)種類很多（見(jiàn)“27”）。只有在特殊情況下，如介質(zhì)中含有固體顆粒、有結(jié)晶析出或高粘度流體中才選用硬對(duì)硬的配對(duì)。當(dāng)選用一軟一硬的配對(duì)時(shí)硬環(huán)端面的寬度比軟環(huán)寬，在硬對(duì)硬的材質(zhì)中可不受此限制。為減少泄漏量和機(jī)械雜質(zhì)進(jìn)入密封端面的可能性，盡量采用內(nèi)裝內(nèi)流式密封結(jié)構(gòu)S選擇導(dǎo)熱性良好的材料做動(dòng)環(huán)，以散出較多的熱量，降低密封端面的溫度。為保證密封環(huán)的整體強(qiáng)度和剛度，環(huán)的壁厚不可太薄。對(duì)于導(dǎo)熱性良好的材料，增加環(huán)厚有利散熱；對(duì)于導(dǎo)熱性欠佳的材料厚度可小些。對(duì)于所受壓力較高的密封環(huán)，要從力學(xué)角度另行設(shè)計(jì)，必要時(shí)采取加固措施。環(huán)的形狀要軸對(duì)稱，以減少其不對(duì)稱的機(jī)械變形和熱變形。動(dòng)環(huán)做補(bǔ)償環(huán)時(shí)，例如國(guó)產(chǎn)104和B104型密封（圖13、圖14），動(dòng)環(huán)和軸（軸套）的（直徑）間隙為0．40～0．60mm，以防止動(dòng)環(huán)在工作中卡住而失去補(bǔ)償能力；靜環(huán)內(nèi)徑要比軸（軸套）大l～2mm，避免兩者摩擦。密封端面的寬度是個(gè)重要參數(shù)，要綜合考慮。三、密封端面的寬度要考慮的因素密封端面的寬度一般是首先決定軟面的寬度，硬面寬度自不待說(shuō)。泄漏量與端面寬度關(guān)系不大。但是，從產(chǎn)生的摩擦熱量來(lái)說(shuō)窄一些較好，產(chǎn)生的熱量較少，溫度梯度小，熱變形也小。</p><p> ***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(guò)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。”一、機(jī)械密封的分類機(jī)械密封近年來(lái)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(wú)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(guò)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)。蕪湖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(duì)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(duì)密封要求更為嚴(yán)格的場(chǎng)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(diǎn)反應(yīng)釜用205型機(jī)械密封為雙端面、多彈簧、、外流、傳動(dòng)套傳動(dòng)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(lái)循環(huán)，整個(gè)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(chǎng)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(diǎn)反應(yīng)釜用206型機(jī)械密封為雙端面、多彈簧、外流、傳動(dòng)套傳動(dòng)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(lái)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(duì)密封要求極嚴(yán)的特殊場(chǎng)合。長(zhǎng)春2007釜用機(jī)械密封</p><p
