七、目前應(yīng)用的密封種類根據(jù)制造方法和材料的不同，目前應(yīng)用的密封環(huán)有整體式密封環(huán)（用同一種材料制造）、組合式密封環(huán)、表面堆焊硬質(zhì)合金和噴涂陶瓷等多種結(jié)構(gòu)。整體式密封環(huán)種類：這種密封環(huán)因用同一種材料制成，材料的性能在密封環(huán)的各個部位均勻一致，沒有組合式密封環(huán)泄漏和分離的缺陷，也沒有電化學(xué)腐蝕的可能。制造軟環(huán)大都用石墨，制造硬環(huán)時可用各種合金鋼，如軸承鋼（GCr9）、高速鋼（W18CrV）及其他合金鋼（如40Cr、3Cr13等），也有的用合金鑄鐵（如硅、鉻和鎳鑄鐵）。采用這些材料時，都要輔之以適當?shù)臒崽幚砉に嚕蕴岣咂溆捕群湍湍バ?。這類材料價格較低，如果使用恰當，也有較長的壽命。為了進一步提高硬度和延長使用壽命，可采用硬質(zhì)合金制造。常用的硬質(zhì)合金為鉆基碳化鎢，性能較好，但價格高，陜西格蘭富泵用機械密封。鋼結(jié)硬質(zhì)合金的價格較低。為了提高在腐蝕介質(zhì)中的耐蝕性，有鎳基碳化鎢，而哈氏合金有更高的耐蝕性，但價格昂貴。此外，還有用碳化硅及其他陶瓷材料制造的密封環(huán)。出現(xiàn)組合式由封環(huán)的原因碳化鎢等材料有優(yōu)良的性能，但是價格高，加工困難，限制了它的使用。為解決這個矛盾，出現(xiàn)了組合式密封環(huán)，陜西格蘭富泵用機械密封，陜西格蘭富泵用機械密封。密封端面采用硬質(zhì)合金，密封環(huán)的基體。山西格蘭富泵用機械密封型號。陜西格蘭富泵用機械密封</p><div

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)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(jié)構(gòu)上。2）突耳傳動。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。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(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。傳動座與彈簧以及彈簧和動環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實現(xiàn)傳動（圖34），當然也有旋向的要求。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。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(jié)構(gòu)，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。例如，對金屬波紋管，則采用焊接；對于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機械密封的動環(huán)的旋轉(zhuǎn)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(zhuǎn)。黑龍江紙漿泵用機械密封寶雞循環(huán)泵用機械密封泄露。</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(zhì)的裂解物沉積會使彈簧阻塞.所以，當溫度超過220℃時就應(yīng)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(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***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?shù)囊后w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(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。</p><p>

特種機械密封是指介質(zhì)、壓力、速度、溫度、結(jié)構(gòu)和用途方面與普通機械密封有所區(qū)別的機械密封，國內(nèi)也稱高參數(shù)機械密封.將機械密封分為普通和特種兩類，是便于說明機械密封的結(jié)構(gòu)、工作條件和使用要求，因此，有的密封廠商除列舉正常密封產(chǎn)品外，也列出高載荷機械密封;有的廠商則將產(chǎn)品樣本以外的機械密封稱作特種機械密封;有的廠商將高溫、高壓、高速的機械密封分別列出或加上標志，以便與普通機械密封產(chǎn)品相區(qū)別;有的廠商則以使用溫度來區(qū)分普通機械密封與特種機械密封.例如，英國克蘭公司將溫度一20~+230℃作為正常產(chǎn)品，超出以上溫度范圍的機械密封，就作為特種機械密封產(chǎn)品來考慮.本章所列的特種機械密封*指釜用、高溫、高壓、高速、低溫、真空和強腐蝕介質(zhì)以及帶磨料介質(zhì)的機械密封釜用機械密封釜用機械密封是指攪拌器(混合器)密封.從引進裝置中使用攪拌器的情況來看，凡大型釜用攪拌器都采用機械密封，它占攪拌器總量的，而未采用機械密封的攪拌器多數(shù)為小功率和堆、槽內(nèi)的小型攪拌器.近年來，機械密封在攪拌器上得到應(yīng)用，一是因為攪拌器軸的擺動量大，有的攪拌軸長達7~8m，雖然有底部支承裝置，但擺動量仍然很大，填料密封已滿足不了要求;二是使用條件越來越苛刻。漢中化工泵用機械密封選型。煙臺紙漿泵用機械密封</p><p

上裝式釜用密封應(yīng)用較廣，它占引進的釜用機械密封95%以上.例如，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，而用上部冷卻風扇(圖3-38)，當操作溫度至300--400℃時，必須采用底部帶法蘭冷卻器(圖io-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，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℃.聚丙烯裝置第1號、2號反應(yīng)釜用攪拌器的機械密封如圖10-3所示：。陜西格蘭富泵用機械密封</p><p
