西德EKATO公司的RD13、RD23、RD200ST和日本炭研精工的2K07T型都是上裝式密封，它們用于PTA、聚乙烯和聚丙烯裝置.上裝式釜用機(jī)械密封的典型結(jié)構(gòu)如圖10-1所示，這是EKATO公司RD200ST型釜用密封的結(jié)構(gòu)圖.這種密封是雙端面帶水冷來套的密封結(jié)構(gòu)，適用操作溫度為130~180℃.如果操作溫度在130℃以下，可以不用水冷夾套，而用上部冷卻風(fēng)扇(圖3-38)，當(dāng)操作溫度至300~400℃時(shí)，必須采用底部帶法蘭冷卻器(圖10-2)的結(jié)構(gòu)，這里法蘭冷卻器起了熱阻擋層的作用.在安裝冷卻水管線時(shí)，要注意冷卻水出口管線與漏斗間高度至少在200mm以上，出口處水的溫度應(yīng)低于40~50℃。有關(guān)釜用密封的密封液貯罐及壓力平衡裝置見第七章第二節(jié)壓力裝置.聚丙烯裝置第1號(hào)、2號(hào)反應(yīng)釜用攪拌器的機(jī)械密封如圖10-3所示.三、底裝式釜用機(jī)械密封反應(yīng)釜底部傳動(dòng)的攪拌器用的機(jī)械密封是一種特殊結(jié)構(gòu)，因?yàn)槊芊馍喜恳c產(chǎn)品接觸，所以工作條件更為苛刻.底裝式釜用機(jī)械密封的要求:1.在結(jié)構(gòu)上做到不使攪拌釜內(nèi)沉積在底部的固體介質(zhì)與機(jī)械密封相接觸;2.當(dāng)密封失效時(shí)，不必排除釜內(nèi)液休也能卸除機(jī)械密封進(jìn)行維修工作，好能快速更換，并能在反應(yīng)釜帶壓下進(jìn)行更換機(jī)械密封，還要求在不拆除笨重的傳動(dòng)機(jī)構(gòu)情況下。江門凱泉泵用機(jī)械密封件廠婁底石家莊工業(yè)泵泵用機(jī)械密封件選型。</p><div

五、與釜用機(jī)械密封有關(guān)的幾個(gè)參數(shù)1.使用壽命釜用機(jī)械密封的使用壽命一般規(guī)定半年以上.其實(shí)使用壽命與攪拌軸的轉(zhuǎn)速、密封尺寸、摩擦副材料等因素有關(guān).圖10-6為EKATO公司對(duì)不同尺寸的密封在不同轉(zhuǎn)速下的使用壽命試驗(yàn)結(jié)果.2.適用范圍釜用密封的適用范圍與使用條件、何種輔助裝置有關(guān)，，每個(gè)密封公司都有其產(chǎn)品適用范圍的說明.圖10-7為EKATO公司RD023和RD200ST型密封在密封液貯罐和壓力平衡裝置兩種條件下的適用范圍圖.高溫機(jī)械密封機(jī)械密封的工作溫度超過80℃時(shí)就作為高溫機(jī)械密封(有的密封公司以工作溫度>90℃為界限)，在高溫下，密封主要間題有下列幾項(xiàng):密封端面液體汽化，摩擦副的熱應(yīng)力和熱變雍，組合件、鑲嵌件可能因配合不當(dāng)而松脫，輔助密封圈因高溫引起的老化、龜裂、粘結(jié)和彈性消失，彈簧疲勞和強(qiáng)度降低，材料的腐蝕和磨損加快.一、高溫機(jī)械密封的要求1.選用耐高溫的密封材料在高溫下，材料的耐溫性能顯得特別重要，合理選用密封材料可使一般結(jié)構(gòu)的機(jī)械密封仍能適用于高溫工作條件，簡化手續(xù)，節(jié)省開支.表10-1列出不同密封材料的使用極限溫度.2.采用金屬波紋管型機(jī)械密封或金屬波紋管與普通機(jī)械密封相結(jié)合的密封結(jié)構(gòu)從耐熱性能來看。</p><p> 熱裝式密封環(huán)進(jìn)行強(qiáng)度校核的方法從傳遞扭矩和密封性的角度可以得出環(huán)與環(huán)座的過盈值，對(duì)此還要進(jìn)行強(qiáng)度校核。對(duì)于環(huán)來講，大都是脆性材料（例如硬質(zhì)合金和石墨等），承受的是擠壓應(yīng)力，在該應(yīng)力作用下，不能斷裂和產(chǎn)生較大的變形。環(huán)中產(chǎn)生的擠壓應(yīng)力為σ1=2*Pm*K12/（K12-1）式中Pm——過盈界面上產(chǎn)生的接觸應(yīng)力P＝e/Cdm＿式中K1——系數(shù)。K1=dm/d1式中C——系數(shù)dm——界面直徑。強(qiáng)度校核應(yīng)滿足σ1＜[σ][σ]=σs/nsσs——材料的屈服極限ns——安全系數(shù)對(duì)一般的強(qiáng)度校核，安全系數(shù)n。＝1．8～2。環(huán)是脆件材料，考慮到密封端面上存在溫度差和不允許有較大變形的具體條件，安全系數(shù)取4。也可校對(duì)其變形量。通常規(guī)定脆性材料的應(yīng)變值為。因此，實(shí)際工作中只校核其相對(duì)應(yīng)變值。即允許相對(duì)應(yīng)變量為0．05%。相對(duì)應(yīng)變量ε=σ1/E1=2PmK12/E1(K12-1)式中E1為環(huán)的彈性模量常用熱裝式密封環(huán)的環(huán)磁材料使用溫度根據(jù)泵送介質(zhì)腐蝕性和介質(zhì)溫度（或密封箱溫度）的不同采用不同的環(huán)座材料。常用的環(huán)座材料有1Cr18Ni9、3Cr13、鈦合金和42#卡朋特合金（CAP42，相當(dāng)于國內(nèi)牌號(hào)4J42）。這些材料線膨脹系數(shù)和耐腐蝕性有較大的差別，使用溫度也不同。前面分析問題的時(shí)候，沒有考慮離心力的影響。寶雞宙斯泵用機(jī)械密封件大全。</p><div

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(qiáng)度和彈性較差，特別是在高溫下，使用一段時(shí)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(qiáng)度和彈性，先彈的機(jī)會(huì)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(yán)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(duì)稱型”波紋管。它具有上述缺陷，為克服此缺陷，出現(xiàn)了“非對(duì)稱型”波紋管。所謂非對(duì)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(shí)斷面形狀趨于對(duì)稱，應(yīng)力趨于均勻（圖44）。同時(shí)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(duì)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(duì)稱型波紋管在國外已投放市場(chǎng)。韶關(guān)襄陽五二五泵用機(jī)械密封件維修。江門凱泉泵用機(jī)械密封件廠</p><p

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機(jī)械密封傳動(dòng)座和動(dòng)環(huán)的傳動(dòng)方式1）銷釘傳動(dòng)。通過推環(huán)，在推環(huán)和動(dòng)環(huán)之間用銷釘實(shí)現(xiàn)傳動(dòng)（圖35），這種傳動(dòng)方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動(dòng)。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動(dòng)環(huán)外緣制成圓弧槽，而將與此接觸的傳動(dòng)座壓成突耳，使之嵌入動(dòng)環(huán)的槽中，實(shí)現(xiàn)傳動(dòng)（圖13）。這種結(jié)構(gòu)可用于大彈簧，也可用于小彈簧的密封結(jié)構(gòu)。3）并圈彈簧傳動(dòng)。傳動(dòng)座與彈簧以及彈簧和動(dòng)環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實(shí)現(xiàn)傳動(dòng)（圖34），當(dāng)然也有旋向的要求。這種結(jié)構(gòu)都用在大彈簧的密封結(jié)構(gòu)上。4）勾圈彈簧傳動(dòng)。為了增加并圈彈簧傳動(dòng)的可靠性，彈簧的兩個(gè)端頭制成彎勾形，分別鉤住傳動(dòng)座和動(dòng)環(huán)（圖36）。5）離合器傳動(dòng)。傳動(dòng)座和動(dòng)環(huán)（或通過推環(huán)）分別制成方形的凸起和缺口，組裝好后凸起插入缺口中實(shí)現(xiàn)傳動(dòng)（圖37）。6）波紋管傳動(dòng)。這種方式是波紋管型密封的特有結(jié)構(gòu)，波紋管兩端分別與傳動(dòng)座和動(dòng)環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對(duì)金屬波紋管，則采用焊接；對(duì)于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機(jī)械密封的動(dòng)環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動(dòng)環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。江門凱泉泵用機(jī)械密封件廠</p><p
