其主要原因是制造金屬波紋管的材料欠佳，大都用181型不銹鋼制造。這種材料耐腐蝕，但強度和彈性較差，特別是在高溫下，使用一段時間后出現(xiàn)“失彈”。國外大都用AM350制造，這是一種沉淀硬化不銹鋼，高溫下仍有足夠的強度和彈性，先彈的機會較少。但是，經(jīng)過長期使約后也暴露了一些缺陷，在波片的焊縫附近開裂。究其原因是在受壓狀態(tài)下。一軸向斷面上各處應(yīng)力分布不均勻，有較嚴重的應(yīng)力集中現(xiàn)象，從而降低了使用壽命?，F(xiàn)有的焊接金屬波紋管其斷面的內(nèi)外緣處（或稱波谷和波峰）、幾何形狀和尺寸是相同的，故也稱為“對稱型”波紋管。它具有上述缺陷，為克服此缺陷，出現(xiàn)了“非對稱型”波紋管。所謂非對稱型波紋管是波谷（內(nèi)緣處）和波峰（外緣處）購肉率半徑不同，波峰大于波谷。在介質(zhì)壓力作用下，迫使其向低壓側(cè)變形，工作時斷面形狀趨于對稱，應(yīng)力趨于均勻（圖44）。同時由于采用了特殊結(jié)構(gòu)的波紋管，焊縫長度縮短。據(jù)國外資料介紹一種13/4英寸的T15WTO型密封，焊縫總長度超過4000mm，而同樣尺寸的非對稱型波紋管密封，焊縫長度*87mm，使密封的可靠性提高，密封能力提高30%，波紋管的彈性提高了40%。非對稱型波紋管在國外已投放市場?；幢盞SB泵用機械密封件維修麗江凝結(jié)水泵泵用機械密封件廠家。</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荷的允許偏差為該負荷的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。O形橡膠密封圈產(chǎn)品非工作面上用標記膠或油漆點表示膠料種類，標記見表9-16。</p><p> 九、波紋管式機械密封波紋管式機械密封的應(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械密封等。焊接金屬波紋管密封的特點焊接金屬波紋管機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，可達600度，可到一200度。此外高速下對軸的振動和振擺適應(yīng)性較強，有很好的補償能力，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。焊接金屬波紋管的彈率的計算由于焊接金屬波紋管機械密封不用彈簧。南寧襄樊五二五泵用機械密封件廠家。</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。為減少泄漏量和機械雜質(zhì)進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械變形和熱變形。動環(huán)做補償環(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。朝陽區(qū)凝結(jié)水泵泵用機械密封件選型?；幢盞SB泵用機械密封件維修</p><p
