用于壓縮機(jī)的高速機(jī)械密封的直徑較大，而用于高速泵的機(jī)械密封尺寸一般都在2in左右.高速泵用的機(jī)械密封以美國約翰克蘭公司(JohnCranePackingCompany)的9AB型密封為典型[圖10-17(a),(b)]，這種密封常用在美國Sundstrand公司高速泵的齒輪箱和泵體的密封上.為了節(jié)省空間并獲得較高的重量與功率比，無論泵的結(jié)構(gòu)和機(jī)械密封結(jié)構(gòu)都很緊湊，一般石油化工公司都引進(jìn)這種高速泵‘，目前揚(yáng)子石油化工公司有關(guān)裝置使用51臺(見表3-41)，中國石油化工總公司系統(tǒng)使用近200臺。圖中60C用于齒輪箱密封，60A或60A+60B用于泵葉輪端密封，棗莊國標(biāo)釜用機(jī)械密封.低溫機(jī)械密封一般低溫機(jī)械密封是指工作溫度在0~-50℃的密封，API-610的低溫含義指溫度低于-29℃，國內(nèi)通常以密封腔溫度低于-20℃為低溫.實際上，低溫范圍較寬，可以劃分為:低溫:-20~-50℃中低溫:-50~-100℃極低溫:-100~-196℃**溫:<-196℃泵送低溫介質(zhì)主要指液化氣體和易揮發(fā)的液體，如液態(tài)氮、液態(tài)氧、甲烷、乙烷、乙烯等液化氣。關(guān)于氮、氧、空氣等液化氣體的物理性能如表10-3所示.關(guān)于乙烯、丙烯、甲烷、乙烷、丙烷的物理性能如圖10-18(a)、(b)、(c)、(d)所示·一，棗莊國標(biāo)釜用機(jī)械密封、低溫機(jī)械密封的要求1，棗莊國標(biāo)釜用機(jī)械密封.材料要求金屬材料隨著溫度降低。安慶FMY212釜用機(jī)械密封件。棗莊國標(biāo)釜用機(jī)械密封</p><div

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(yīng)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(xiàn)記載，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(jī)器設(shè)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(bǔ)償環(huán)和非補(bǔ)償環(huán)之分。當(dāng)補(bǔ)償機(jī)構(gòu)設(shè)計在動環(huán)一側(cè)時，密封端面磨損后，靜環(huán)不能進(jìn)行補(bǔ)償，叫做非補(bǔ)償型靜環(huán)。反之，稱為補(bǔ)償型靜環(huán)，當(dāng)密封端面磨損后，靜環(huán)在彈性元件作用下，做軸向移動進(jìn)行補(bǔ)償。非補(bǔ)償型靜環(huán)應(yīng)用較多，都用于旋轉(zhuǎn)型密封。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)。棗莊國標(biāo)釜用機(jī)械密封淮北M481釜用機(jī)械密封件。</p><div

多采用以下幾種方式固定：1）螺帽固定（見圖3）。這種結(jié)構(gòu)要求軸上帶有凸臺，動環(huán)斷面為“L”形，動環(huán)裝入后用短套頂住，外面用圓螺帽旋緊。為防止介質(zhì)沿動環(huán)泄漏，在動環(huán)和軸套凸臺端面有密封圈。集裝式密封的動環(huán)也可用螺帽固定，和前者不同的是動環(huán)的螺帽從內(nèi)部旋緊，事先組裝好后再將整體機(jī)械密封向泵上安裝。2）螺釘傳動（圖38）。動環(huán)的后部端面鉆有螺釘孔并帶螺紋，軸套上帶有突緣，用螺釘將動環(huán)和軸套的突緣聯(lián)接在一起，中間設(shè)墊片防止介質(zhì)沿動環(huán)和軸套之間泄漏。3)頂絲傳動（圖39）。這種結(jié)構(gòu)實際上增加了一個傳動套，該套用頂絲固定在軸上，動環(huán)用銷釘與其傳動，在傳動套和軸以及動環(huán)和傳動套之間均設(shè)有密封圈。這種動環(huán)結(jié)構(gòu)較為復(fù)雜，但其浮動性得到了改善。4）銷釘傳動（圖40）。該種傳動省略了圖39的傳動套，動環(huán)和軸用銷釘傳動，其軸向靠臺階定位，顯然這種動環(huán)和軸沒有剛性聯(lián)接，浮動性很好。旋轉(zhuǎn)型機(jī)械密封的靜環(huán)防轉(zhuǎn)方法1）浮動型靜環(huán)。在靜環(huán)尾端設(shè)一開口，防轉(zhuǎn)銷插入此開口，起到靜環(huán)防轉(zhuǎn)作用。該結(jié)構(gòu)簡單，安裝方便，靜環(huán)的浮動性好，得到***的應(yīng)用。按防轉(zhuǎn)銷安裝位置可分為徑向和軸向兩種（圖41），其中軸向防轉(zhuǎn)銷用的較多。這種結(jié)構(gòu)有個缺點(diǎn)。</p><p> 輔助密封圈是機(jī)械密封上**薄弱環(huán)節(jié)，當(dāng)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(zhì)的裂解物沉積會使彈簧阻塞.所以，當(dāng)溫度超過220℃時就應(yīng)采用金屬波紋管型機(jī)械密封，或者采用金屬波紋管與普通機(jī)械密封相結(jié)合的密封結(jié)構(gòu).3.采取冷卻措施在高溫下，為了使密封可靠運(yùn)行，盡可能對機(jī)械密封進(jìn)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(jìn)行溫度控制，常用的溫度控制有沖洗、阻封、加強(qiáng)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(dāng)?shù)囊后w時，也可通人氮?dú)狻鍤?，以防止空氣引起的氧?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(shù)有差異，在高溫下使用時會產(chǎn)生摩擦環(huán)松動、脫落。因此，對鑲嵌結(jié)構(gòu)的摩擦環(huán)采用的溫度應(yīng)予以特別注意.熱鑲結(jié)構(gòu)產(chǎn)生松動、脫落的原因，除了與使用溫度有關(guān)外。濰坊2009釜用機(jī)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(dá)980℃，在-196℃的低溫下屈服強(qiáng)度可達(dá)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(jī)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(zhì)借助于輸送裝置，通過冷卻器再進(jìn)人密封，則59B型密封仍可用于介質(zhì)溫度大于230℃的場合.例如，芳烴裝置釜液泵GA-116AB的介質(zhì)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(jī)械密封介紹上海水泵廠引進(jìn)美國EG&GSEALOL公司技術(shù)，已生產(chǎn)多種系列的密封，其中605系列是焊接波紋管機(jī)械密封，它的型號、規(guī)格和使用性能如表10-2所示.高壓機(jī)械密封通常認(rèn)為，當(dāng)機(jī)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(dá)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(rèn)為在高壓下，由于機(jī)械和熱變形危害機(jī)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(biāo)準(zhǔn)型密封要求設(shè)計改進(jìn)。天門MR-D釜用機(jī)械密封件。棗莊國標(biāo)釜用機(jī)械密封</p><p
