九、波紋管式機(jī)械密封波紋管式機(jī)械密封的應(yīng)用范圍很廣，從低溫到高溫，從中性介質(zhì)到腐蝕性介質(zhì)，從低速到高速，從普通到苛刻的工作條件都可選用。所有這些可通過變更波紋管的幾何形狀（如內(nèi)外徑、波片厚度和波數(shù)等）與材料彈性模量，改變波紋管的彈率。根據(jù)介質(zhì)的腐蝕性能，選用不同的波紋管材料等。例如對工作壓力和溫度都不高的中性介質(zhì)（油和水等），太原205釜用機(jī)械密封件，可選用橡膠制造的簡易波紋管密封；在腐蝕性介質(zhì)中（酸或減等），可選用四氟制造的波紋管密封；高溫和高速下，可采用焊接金屬波紋管機(jī)械密封等。焊接金屬波紋管密封的特點(diǎn)焊接金屬波紋管機(jī)械密封用的波紋管是由軋制的金屬薄板沖裁成環(huán)形波紋狀的型面，波形多采用S形，將許多個波片重疊起來，分別在環(huán)形的外緣和內(nèi)緣進(jìn)行焊接，組成一個波紋管，兩端再與傳動座和動環(huán)焊接成整體。除了不用輔助密封圈外，太原205釜用機(jī)械密封件，還具備使用溫度范圍廣的特點(diǎn)，高可達(dá)600度，低可到一200度，太原205釜用機(jī)械密封件。此外高速下對軸的振動和振擺適應(yīng)性較強(qiáng)，有很好的補(bǔ)償能力，保證密封端面良好地貼合。但是長期在高溫下工作的焊接金屬波紋管密封，波紋管的彈率有減小的趨勢（俗稱“失彈”），使用受到一定的限制。威海M481釜用機(jī)械密封件。太原205釜用機(jī)械密封件</p><div

圖29）旋轉(zhuǎn)式機(jī)械密封軸套和傳動座傳動方式：l）頂絲傳動（圖30）。傳動座用1～2個頂絲固定在軸套表面上，結(jié)構(gòu)簡單，但是安裝時軸套需從軸上取出，方能緊固頂絲。這種結(jié)構(gòu)要求在軸套表面（與頂絲接觸的部位）劃一凹坑，否則運(yùn)轉(zhuǎn)中易出現(xiàn)傳動失效，傳動座會發(fā)生軸向串動。在直徑較大和溫度較高時，不能采用單純的頂絲傳動。2）頂絲一臺階傳動（圖31）。為了克服單純頂絲傳動時，傳動座軸向串動，可在軸套上設(shè)一臺階，傳動座頂靠在幼查臺階端面，體傳動成無法串動定位，用鍵來帶動軸套旋轉(zhuǎn)。這種結(jié)構(gòu)簡單，安裝方便，現(xiàn)場施工時可不用拆卸軸套即可安裝傳動座，使用可靠，運(yùn)動中不會產(chǎn)生傳動失效。3）鍵傳動。4）撥叉?zhèn)鲃樱▓D33）。是鍵傳動基礎(chǔ)上改進(jìn)的，軸套上仍有臺階，傳動座為沖壓件，上面有兩個小“爪”（撥叉）伸到軸套臺階的槽中實(shí)現(xiàn)傳動，結(jié)構(gòu)也很簡單。由于是沖壓件，撥叉徑向尺寸小（較?。?，沖壓后冷作硬化，撥叉易斷裂。在中性介質(zhì)中尚可使甩。5)彈簧傳動。這種傳動方式不用傳動座，傳動彈簧依靠過盈值旋緊在軸套上，并傳遞扭矩，彈簧的端部靠緊軸套的臺階處（圖34），防止軸向位移。這種方式結(jié)構(gòu)簡單，安裝方便，但對彈簧的旋向有要求，泵軸旋轉(zhuǎn)時。大同國標(biāo)釜用機(jī)械密封張家口FMY212釜用機(jī)械密封廠家。</p><div

多采用以下幾種方式固定：1）螺帽固定（見圖3）。這種結(jié)構(gòu)要求軸上帶有凸臺，動環(huán)斷面為“L”形，動環(huán)裝入后用短套頂住，外面用圓螺帽旋緊。為防止介質(zhì)沿動環(huán)泄漏，在動環(huán)和軸套凸臺端面有密封圈。集裝式密封的動環(huán)也可用螺帽固定，和前者不同的是動環(huán)的螺帽從內(nèi)部旋緊，事先組裝好后再將整體機(jī)械密封向泵上安裝。2）螺釘傳動（圖38）。動環(huán)的后部端面鉆有螺釘孔并帶螺紋，軸套上帶有突緣，用螺釘將動環(huán)和軸套的突緣聯(lián)接在一起，中間設(shè)墊片防止介質(zhì)沿動環(huán)和軸套之間泄漏。3)頂絲傳動（圖39）。這種結(jié)構(gòu)實(shí)際上增加了一個傳動套，該套用頂絲固定在軸上，動環(huán)用銷釘與其傳動，在傳動套和軸以及動環(huán)和傳動套之間均設(shè)有密封圈。這種動環(huán)結(jié)構(gòu)較為復(fù)雜，但其浮動性得到了改善。4）銷釘傳動（圖40）。該種傳動省略了圖39的傳動套，動環(huán)和軸用銷釘傳動，其軸向靠臺階定位，顯然這種動環(huán)和軸沒有剛性聯(lián)接，浮動性很好。旋轉(zhuǎn)型機(jī)械密封的靜環(huán)防轉(zhuǎn)方法1）浮動型靜環(huán)。在靜環(huán)尾端設(shè)一開口，防轉(zhuǎn)銷插入此開口，起到靜環(huán)防轉(zhuǎn)作用。該結(jié)構(gòu)簡單，安裝方便，靜環(huán)的浮動性好，得到***的應(yīng)用。按防轉(zhuǎn)銷安裝位置可分為徑向和軸向兩種（圖41），其中軸向防轉(zhuǎn)銷用的較多。這種結(jié)構(gòu)有個缺點(diǎn)。</p><p> 不太適用.5.采用雜質(zhì)過濾輔助裝置，象旋液分離器分離雜質(zhì)效果較好，結(jié)構(gòu)簡單(見第七章第三節(jié)雜質(zhì)過濾裝置).二、離粘度介質(zhì)的機(jī)械密封通常液體的比重在，足夠?qū)Υ蠖鄶?shù)密封混合.液體的比重低于.粘度如同比重一樣，是表示液體的潤滑性質(zhì)，液體具有較高枯度常常具有較好的潤滑特性.液體粘度低于·S時用標(biāo)準(zhǔn)設(shè)計，不要進(jìn)行什么修改.對于粘度為·S的液體，要求密封有可靠的驅(qū)動設(shè)計一重載荷承壓裝置，這是為了補(bǔ)償在粘稠環(huán)境下的在密封面上增加的剪切力.另外，還要加強(qiáng)周圍環(huán)境控制，對密封面進(jìn)行適當(dāng)潤滑.當(dāng)摘送高粘度介質(zhì)時，密封面之間無液膜存在，必須采用單端面密封帶外沖洗，單端面密封帶外潤滑或雙端面密封帶外封液.揚(yáng)子石油化工公司各引進(jìn)裝置工藝介質(zhì)在使用溫度下的粘度都沒有超過Pa·S，只有燃料油的粘度在Pa·s之間，其它介質(zhì)的粘度很少超過·S.真空機(jī)械密封真空機(jī)械密封廣用于冶金、石油化工、醫(yī)藥、食品、電子領(lǐng)域.真空密封是指在有一定真空度的某一裝置中采用密封技術(shù)，使大氣不致滲入而保持其一定的真空度.真空技術(shù)中所采用的壓強(qiáng)單位為Torr，相當(dāng)于1/760標(biāo)準(zhǔn)大氣壓或1mm高度的汞柱()。石油化工用的機(jī)械密封以低真空較多。石家莊207釜用機(jī)械密封廠家。</p><div

硬環(huán)的材質(zhì)種類很多（見“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硬的配對。當(dāng)選用一軟一硬的配對時硬環(huán)端面的寬度比軟環(huán)寬，在硬對硬的材質(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。對于導(dǎo)熱性良好的材料，增加環(huán)厚有利散熱；對于導(dǎo)熱性欠佳的材料厚度可小些。對于所受壓力較高的密封環(huán)，要從力學(xué)角度另行設(shè)計，必要時采取加固措施。環(huán)的形狀要軸對稱，以減少其不對稱的機(jī)械變形和熱變形。動環(huán)做補(bǔ)償環(huán)時，例如國產(chǎn)104和B104型密封（圖13、圖14），動環(huán)和軸（軸套）的（直徑）間隙為0．40～0．60mm，以防止動環(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。泄漏量與端面寬度關(guān)系不大。但是，從產(chǎn)生的摩擦熱量來說窄一些較好，產(chǎn)生的熱量較少，溫度梯度小，熱變形也小。蕪湖M461釜用機(jī)械密封件。太原205釜用機(jī)械密封件</p><p style="text-indent:25px">滄州204B釜用機(jī)械密封廠家。太原205釜用機(jī)械密封件</p><p> 纏繞式波形彈簧材料可選用SU302、SUS304、SUA631J1和SUSS632等，材料的化學(xué)成應(yīng)符合GB/T3280-2008、GB/T4238-2007的規(guī)定，材料的尺寸精度要按表9-12規(guī)定。扁帶材料外表光滑，無凹坑、劃傷、斷裂、裂縫和其他物理缺陷，邊緣為圓形。纏繞式波形彈簧工作負(fù)荷的允許偏差為該負(fù)荷的10%。各種類型纏繞式波形彈簧的疲勞性能應(yīng)符合表9-13要求。3形橡膠密封圈的技術(shù)要求由于橡膠是彈性材料，在負(fù)荷作用下發(fā)生變形，尤其是在壓力高的場合合下，會使密封圈擠入密封間隙，影響浮動性而使密封失效。因此。要根據(jù)使用壓力合理選擇O形橡膠密封圈的硬度和其截面直徑。一般高壓時選擇硬度較高的密封圈.低壓時選擇硬度較低的密封圈。常用橡膠O形圈的硬度為邵氏70±5。制造機(jī)械密封用O形圈的模具分模面盡量避開內(nèi)外側(cè)及上下側(cè)的工作面，一般采用45°開模，以保證良好的密封性能。截面尺寸要均勻，其截面形狀參考圖，不得存在凹凸不平、氣泡、雜質(zhì)等缺陷。O形橡膠密封圈內(nèi)徑極限偏差見表9-14，截面直徑偏差見表915。太原205釜用機(jī)械密封件</p></p><br
