使彈簧旋緊而不是旋松，這是必須指出的。旋轉式機械密封傳動座和動環(huán)的傳動方式1）銷釘傳動。通過推環(huán)，在推環(huán)和動環(huán)之間用銷釘實現(xiàn)傳動（圖35），這種傳動方式多用在小彈簧的結構上。2）突耳傳動。國內生產的104型密封即采用此種結構。在動環(huán)外緣制成圓弧槽，而將與此接觸的傳動座壓成突耳，使之嵌入動環(huán)的槽中，實現(xiàn)傳動（圖13）。這種結構可用于大彈簧，也可用于小彈簧的密封結構。3）并圈彈簧傳動。傳動座與彈簧以及彈簧和動環(huán)之間，完全依靠大彈簧內徑的過盈值實現(xiàn)傳動（圖34），當然也有旋向的要求。這種結構都用在大彈簧的密封結構上。4）勾圈彈簧傳動。為了增加并圈彈簧傳動的可靠性，彈簧的兩個端頭制成彎勾形，分別鉤住傳動座和動環(huán)（圖36）。5）離合器傳動。傳動座和動環(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現(xiàn)傳動（圖37）。6）波紋管傳動。這種方式是波紋管型密封的特有結構，波紋管兩端分別與傳動座和動環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定，青島207釜用機械密封。例如，對金屬波紋管，則采用焊接；對于橡膠和四氟波紋管，青島207釜用機械密封，青島207釜用機械密封，則采用整體或其他方式聯(lián)接。靜止式機械密封的動環(huán)的旋轉靜止式機械密封的動環(huán)直接固定在軸（軸套）上，隨軸一起旋轉。蘇州207釜用機械密封件。青島207釜用機械密封</p><div

比YG6大1倍多，為／℃（10～500℃時）。這兩點決定了耐熱沖擊性能不如YG6好。正因為線膨脹系數較大，和馬氏體不銹鋼接近（10～500℃時為11X10-6／℃），為和環(huán)座焊接提供了有利條件。焊接時需在環(huán)和座之間鋪放一層鎳基粉末，置于真空電阻爐中，經1100℃高溫熔焊，然后進行回火處理，以消除焊接應力。由于是焊接的密封環(huán)，硬質合金環(huán)的厚度可以比YG6薄，毛坯的厚度也只有3～3．5mm。以因密度小，是YG6的一半（7~），因此，可節(jié)約貴重金屬，價格較低。這種合金的牌號為CN15，其中Cr3C285%，Ni為15%，由北京硬質合金廠研制成功。熱裝式密封環(huán)以其性能***應用，但過盈量過大則硬質合金在較大擠壓應力作用下產生變形；過盈量過小，使用時會松脫。經長期觀察分析，熱裝式密封環(huán)松脫主要是由于環(huán)座和硬質合金環(huán)兩者線膨脹純利系數的差別，工作出現(xiàn)間隙。由此可見，熱裝式密封環(huán)失效的根本原因主要有二：一是過盈值小，三是環(huán)座材料選擇不當，線膨脹系數太大。確定過盈值應遵循的原則：1）從傳遞扭矩的角度考慮過盈值應足夠大。2）從環(huán)的變形的角度考慮過盈值不可過大。綜合起來，在滿足環(huán)和座傳遞扭矩的情況下，取小的過盈值。日照內置釜用機械密封天門MR-D釜用機械密封件。</p><div

輔助密封圈是機械密封上**薄弱環(huán)節(jié)，當溫度超過80℃時普通橡膠已不適用，溫度超過230~250℃，聚四氟乙烯也不能使用.此外，由于高溫、易燃介質的裂解物沉積會使彈簧阻塞.所以，當溫度超過220℃時就應采用金屬波紋管型機械密封，或者采用金屬波紋管與普通機械密封相結合的密封結構.3.采取冷卻措施在高溫下，為了使密封可靠運行，盡可能對機械密封進行冷卻，要避免在干摩擦狀態(tài)下工作.必須保持密封間隙中的溫度在密封液的汽化溫度以下.冷卻措施就是對密封進行溫度控制，常用的溫度控制有沖洗、阻封、加強液體循環(huán)等(詳見第七章一節(jié)溫度控制裝置)。在高溫下，還可采用以下措施:(1)用Diphy1(二苯及二苯氧化物的混合物)作為阻封液，它是冷態(tài)無壓的換熱劑(阻封液由泵效螺旋輸送);(2)在超高溫下或者沒有適當的液體時，也可通人氮氣、氬氣，以防止空氣引起的氧化.4.鑲嵌摩擦副問題密封環(huán)鑲嵌是充分利用端面材料和基體材料的特性，提高材料使用價值，一般對高溫密封采用熱鑲法.但是，由于端面耐磨材料和基體材料的熱脹系數有差異，在高溫下使用時會產生摩擦環(huán)松動、脫落。因此，對鑲嵌結構的摩擦環(huán)采用的溫度應予以特別注意.熱鑲結構產生松動、脫落的原因，除了與使用溫度有關外。</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品。對于強腐蝕介質的泵用機械密封，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品為主，其機械密封的特點如下:1.產品系列化、標準化，密封元件通用性好，按外商產品樣本說明，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.結構多數采用平衡型，多彈簧，V形密封圈.例如，乙烯裝置泵用機械密封平衡型占，多彈簧結構占,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、結構如表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。鎮(zhèn)江M461釜用機械密封件。</p><div

圖3-22)Y4D型金屬波紋管密封是Eagle公司用于低壓(()，溫度-200~+400℃密封。波紋管采用Inconel718材料，這種合金的耐氧化性能可達980℃，在-196℃的低溫下屈服強度可達1426N/mm2.因此，Inconel718在高低溫條件下都適用.尤里卡裝置中凡高溫的減壓渣油，KSK油，輕、重瓦斯油的密封都采用Y4D型金屬波紋管機械密封.(圖3-10)雖然59B型密封的使用溫度范圍為-50~十230℃，如果泵送介質借助于輸送裝置，通過冷卻器再進人密封，則59B型密封仍可用于介質溫度大于230℃的場合.例如，芳烴裝置釜液泵GA-116AB的介質溫度為290℃，就是采用外冷卻的59B型密封.4.上海水泵廠605系列波紋管機械密封介紹上海水泵廠引進美國EG&GSEALOL公司技術，已生產多種系列的密封，其中605系列是焊接波紋管機械密封，它的型號、規(guī)格和使用性能如表10-2所示.高壓機械密封通常認為，當機械密封的工作壓力超過4~5MPa時就視作高壓，有的密封公司把工作壓力達到3MPa就作為高壓;有的公司以PV值大小來衡量;有的公司則將壓力和溫度一起考慮.一般認為在高壓下，由于機械和熱變形危害機械密封的功能和可靠性，壓力越高，危害性越大.所以，用于極高壓力的密封比標準型密封要求設計改進。哈爾濱207釜用機械密封件。阜陽生產釜用機械密封</p><p
