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***的特點，**高可達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，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。</p><p> 還與軸徑尺寸有關(guān).當摩擦副環(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、高溫機械密封實例芳烴裝置循環(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，進口壓力，出口壓力~175MPa，機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.(圖3-22)Y4D型金屬波紋管密封是Eagle公司用于低壓(()。嘉峪關(guān)襄樊五二五泵用機械密封選型。</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.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節(jié)低溫泵輔助系統(tǒng)。二、低溫甲烷泵機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)，不必擔心低溫時發(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。延安格蘭富泵用機械密封選型。內(nèi)蒙古潛污泵用機械密封</p><p
