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。昌平區(qū)大軸徑釜用機(jī)械密封三門峽M481釜用機(jī)械密封件。</p><div

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），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，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。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。</p><p> 西德KSB泵廠選用英國克蘭公司和西德布格曼公司的產(chǎn)品。對于強(qiáng)腐蝕介質(zhì)的泵用機(jī)械密封，則采用西德Wernert、日本Eagl。和英國充蘭公司等波紋管型機(jī)械密封.第二國外機(jī)械密封特點(diǎn)揚(yáng)子石油化工公司引進(jìn)的泵和釜類設(shè)備涉及日本、’美國、英國、法國、西德、荷蘭和瑞士等國家，設(shè)備所用的機(jī)械密封以日本、美國、英國和西德等國大型的密封公司產(chǎn)品為主，其機(jī)械密封的特點(diǎn)如下:1.產(chǎn)品系列化、標(biāo)準(zhǔn)化，密封元件通用性好，按外商產(chǎn)品樣本說明，同一規(guī)格可以互換。2.品種、規(guī)格齊全，能滿足現(xiàn)代工業(yè)要求.凡石油化工生產(chǎn)中需要的高溫、高壓、高速、低溫、耐蝕和耐磨的機(jī)械密封都能供應(yīng)，表2-3列舉的是有關(guān)裝置一部分使用特種機(jī)械密封的場所.3.結(jié)構(gòu)多數(shù)采用平衡型，多彈簧，V形密封圈.例如，乙烯裝置泵用機(jī)械密封平衡型占，多彈簧結(jié)構(gòu)占,V形密封圈占%.從泵用機(jī)械密封的密封端面布置來看.單端面占92%，雙端面占8%.雙端面以背對背(back-to-back)組合為主，個別是串聯(lián)(Tandem)組合.此外，泵用密封中有80臺波紋管密封(占%).各裝置使用機(jī)械密封的型號、結(jié)構(gòu)如表2-44.材料特點(diǎn).從外商提供的資料可以看出，它們除了按照API-610,DIN24960等有關(guān)機(jī)械密封用材料的規(guī)定之外。湘潭212釜用機(jī)械密封件。</p><div

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。濰坊M461釜用機(jī)械密封件。昌平區(qū)大軸徑釜用機(jī)械密封</p><p

其缺點(diǎn)是有的波紋管彈力較小，需加輔助彈簧，如（圖8a）所示。集裝式機(jī)械密封是將普通的機(jī)械密封、軸套和密封壓蓋預(yù)先組合成一個整體，將其安裝到泵上后，不做任何調(diào)整（包括彈簧的壓縮量），只固定軸套和壓蓋，再把剖分式卡環(huán)取下（圖12中的A）即可投入使用。由此可見，卡環(huán)的（軸向）寬度等于彈簧的壓縮量，并且，從外部就可以知道該值的大小和變化情況。事先組裝，容易保證密封的安裝質(zhì)量，可減少因安裝不良引起的失效。近年來集裝式密封發(fā)展很快，因卡環(huán)的結(jié)構(gòu)、軸套與軸的傳動以及軸與軸套之間的密封等方面的不同，出現(xiàn)了許多種集裝式密封。三、國產(chǎn)104型機(jī)械密封國產(chǎn)104型機(jī)械密封為內(nèi)裝、內(nèi)流、單端面、單彈簧、非平衡型密封，輔助密封圈有V形和O形兩種型式（圖13）。3104型機(jī)械密封中的字母“B”表示平衡型密封，其余結(jié)構(gòu)和104型完全相同。B104型密封相當(dāng)于舊標(biāo)準(zhǔn)（JB1472－75）的110型(GY型)。兩種密封型式工作條件基本相同，*壓力不同。密封腔內(nèi)的溫度一20～80℃，轉(zhuǎn)速不大于3000r／min，介質(zhì)為清水、油類及其它弱腐蝕性液體。104型密封腔中的壓力為0～0．8MPa，而B104型適用壓力為0．6～3．0MPa。經(jīng)過二十多年的實(shí)踐，證明這兩種密封結(jié)構(gòu)簡單，使用可靠。因此。寶雞204型釜用機(jī)械密封</p><p
