目前動環(huán)和軸套的密封方法可分為三類：輔助密封圈軸向安裝的動環(huán)、輔助密封圈徑向安裝的動環(huán)和帶波紋管的動環(huán)。輔助密封圈軸向安裝的動環(huán)（圖18），靠彈簧力壓緊密封圈來實現(xiàn)密封。彈簧力可視為不變化，密封可靠、使用壽一命長、安裝較方便，從而得到***應用。輔助密封圈徑向安裝的動環(huán)（圖19），靠密封圈的過盈和彈性實現(xiàn)密封，其材料大多用聚四氟乙烯和合成橡膠。隨著使用時間的延長，這兩種材料分別出現(xiàn)冷流變形和老化而喪失彈性。有文獻記載，南昌207型釜用機械密封，這種結(jié)構(gòu)的密封，有40%的失效發(fā)生在輔助密封圈部位。第三種動環(huán)是指波紋管型密封，將動環(huán)和波紋管制成一個整體（圖8），故不需要動環(huán)密封圈。靜環(huán)安裝在機器設備的殼體、壓蓋、法蘭等靜止部位上，它與動環(huán)組成的密封端面防止介質(zhì)泄漏，也有補償環(huán)和非補償環(huán)之分。當補償機構(gòu)設計在動環(huán)一側(cè)時，密封端面磨損后，靜環(huán)不能進行補償，叫做非補償型靜環(huán)。反之，稱為補償型靜環(huán)，當密封端面磨損后，靜環(huán)在彈性元件作用下，做軸向移動進行補償。非補償型靜環(huán)應用較多，都用于旋轉(zhuǎn)型密封，南昌207型釜用機械密封，南昌207型釜用機械密封。靜環(huán)與壓蓋的密封和固定方式有兩種，一是浮動型，一是固定型。具體的結(jié)構(gòu)種類很多，圖20和圖21給出了較為典型的結(jié)構(gòu)。蘇州FMY212釜用機械密封件。南昌207型釜用機械密封</p><div

在有的國家已成為主要的軸封方式。國內(nèi)的焊接金屬波紋管密封質(zhì)量不夠穩(wěn)定，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力分布不均勻，有較嚴重的應力集中現(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%。廈門雙端面釜用機械密封哈爾濱207釜用機械密封件。</p><div

也采用316型不銹鋼做彈簧材料.碟形彈簧用于乙醛裝置.這種短形結(jié)構(gòu)彈簧，使密封更加緊湊.碟形彈簧材料用HastelloyC4合金(相當于DIN材料號)和GrNiMo不銹鋼材料.(5)波紋管材料有Inconel}鉻鎳鐵洽金、F聚四氟乙烯、氯磺化聚乙烯橡(Iiypalon)和丁睛橡膠.金屬波紋管采用焊接結(jié)構(gòu)，(6)V形密封圈采用聚四氟乙烯材料，典型牌號是泰弗隆(Teflon).O形密封圈采用丁睛橡膠(NBR)和氟橡膠(Viton}，有的密封公司為了提高耐蝕性能，建議用橡膠圈外包覆聚四氟乙烯的0形圈。有幾個密封公司推薦既具有橡膠彈性又具有聚四氟乙烯耐蝕性能的材料kalrez，它是美國杜邦公司新近推出的合成橡膠材料，已有Kalrez材料的0形圈系列產(chǎn)品.5公制密封件占大多數(shù)。從現(xiàn)有引進的機械密封套數(shù)可以看出，英制密封只占8%左右。另外從英國克蘭密封公司的產(chǎn)品介紹中也可看出該公.司逐步向公制化過渡，有的產(chǎn)品則是公、英制同時生產(chǎn)。6.推行IS03069-74密封腔尺寸標準。自1974年國際標準化組織制訂IS03069密封腔尺寸的規(guī)定以來，各國密封公司相繼采用IS03069-74標準，幾個大的密封公司在產(chǎn)品樣本中幾乎都注明哪些品種適用于ISO-3069的尺寸系列.這些公司有:英國克蘭公司，日本比拉公司、日本Eagl。</p><p> 也可采用內(nèi)裝式結(jié)構(gòu).實際上，引進裝置工藝泵的機械密封絕大部分為內(nèi)裝式密封.輸送危險性大的介質(zhì)，可選用雙端面密封結(jié)構(gòu)，并引人隔離液保護.此外，也可采用彈簧帶有保護層的措施.例如，彈簧外加套塑料軟管或噴涂一層防腐層，圖10-22為彈簧加保護套的密封結(jié)構(gòu).2.材質(zhì)上選用耐腐蝕材科推薦耐蝕材質(zhì)，這是根本出路.石油化工引進裝置所用.的機械密封大部分從材質(zhì)上解決了耐蝕問題，·所以在國外大的密封公司的樣本或手冊中都備有不同介質(zhì)所對應的密封型號選定表.3.對泄漏的腐蝕性或有毒的介質(zhì)進行收集、安全排放或處理后排放.例如，有的帶回收液盤，有的裝排放管線，圖上標明排放至安全區(qū)域.揚子石油化工公司引進裝置應角的機械密封大部分為耐腐蝕的密封，典型的如英國克蘭公司的59U、59B和10T型，日本比拉公司的BB8型和Eagle公司Y4D。型，西德布格曼公司TF型和Wernert公司橡膠波紋管(ConcertinaWalls)型密封.國內(nèi)用于耐腐蝕泵用機械密封有:151、152、153、154型.結(jié)構(gòu)如圖10-23、10-24、10-25、10-26所示.含有磨料介質(zhì)和高粘度介質(zhì)的機械密封密封介質(zhì)一般總有雜質(zhì)，所以要經(jīng)過處理，就是經(jīng)過處理的介質(zhì)也會在工藝過程中產(chǎn)生結(jié)晶、凝固和反應物析出?；幢盡481釜用機械密封件。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南昌207型釜用機械密封,釜用機械密封"

五、與釜用機械密封有關的幾個參數(shù)1.使用壽命釜用機械密封的使用壽命一般規(guī)定半年以上.其實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.圖10-6為EKATO公司對不同尺寸的密封在不同轉(zhuǎn)速下的使用壽命試驗結(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，，每個密封公司都有其產(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.高溫機械密封機械密封的工作溫度超過80℃時就作為高溫機械密封(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:密封端面液體汽化，摩擦副的熱應力和熱變雍，組合件、鑲嵌件可能因配合不當而松脫，輔助密封圈因高溫引起的老化、龜裂、粘結(jié)和彈性消失，彈簧疲勞和強度降低，材料的腐蝕和磨損加快.一、高溫機械密封的要求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械密封或金屬波紋管與普通機械密封相結(jié)合的密封結(jié)構(gòu)從耐熱性能來看。德州M481釜用機械密封件。錦州整套釜用機械密封</p><p style="text-indent:25px">石家莊207釜用機械密封廠家。南昌207型釜用機械密封</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。對于強腐蝕介質(zhì)的泵用機械密封，則采用西德Wernert、日本Eagl。和英國充蘭公司等波紋管型機械密封.第二國外機械密封特點揚子石油化工公司引進的泵和釜類設備涉及日本、’美國、英國、法國、西德、荷蘭和瑞士等國家，設備所用的機械密封以日本、美國、英國和西德等國大型的密封公司產(chǎn)品為主，其機械密封的特點如下:1.產(chǎn)品系列化、標準化，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、耐蝕和耐磨的機械密封都能供應，表2-3列舉的是有關裝置一部分使用特種機械密封的場所.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%).各裝置使用機械密封的型號、結(jié)構(gòu)如表2-44.材料特點.從外商提供的資料可以看出，它們除了按照API-610,DIN24960等有關機械密封用材料的規(guī)定之外。南昌207型釜用機械密封</p><p
