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。蕪湖雙端面釜用機(jī)械密封廈門MR-D釜用機(jī)械密封件。</p><div

焊接金屬波紋管的彈率的計(jì)算由于焊接金屬波紋管機(jī)械密封不用彈簧，彈性力完全由波紋管產(chǎn)生，因此波紋管設(shè)計(jì)時(shí)要考慮其彈率。一般將波紋管的彈率設(shè)計(jì)得小些，當(dāng)要求一定的彈力時(shí)，波紋管的壓縮量就要適當(dāng)?shù)丶哟蟆＿\(yùn)轉(zhuǎn)相當(dāng)長時(shí)間后，如果密封端面磨損，波紋管自動(dòng)補(bǔ)償，而彈力降低不會(huì)大，始終保持密封端面有足夠的壓比。為保證足夠的彈性力，壓縮量在10mm左右，低不能低于6mm。工作時(shí)每個(gè)波的變形以小為宜，為保證一定的壓縮量，要適當(dāng)增加波數(shù)，保持波距。一般波數(shù)取16～20，溫度和壓力高時(shí)波數(shù)宜取多。波紋管的彈率是幾何形狀和材料的函數(shù)，常用下式計(jì)算：k=πEt3(c)d2/2nB3d1式中k——波紋管彈率，N／mm；E——材料在工作溫度下的彈性模量，N/mm2；t——波片厚度，mmn——波紋管波數(shù)；d1、d2——分別為波紋管的內(nèi)外徑，mm；B——波紋管的片寬，mm。B=（d2-d1）／2公式中沒有考慮波片的斷面形狀等因素，因此有一定的誤差。實(shí)際工作中可在彈簧測力計(jì)上測量其彈率。普通彈簧的彈率計(jì)算在一般“機(jī)械零件”書上能找到，故在此不作介紹。非對(duì)稱型波紋管焊接金屬波紋管機(jī)械密封以其結(jié)構(gòu)簡單、伸縮性好和耐高溫等優(yōu)點(diǎn)，得到了日益廣的應(yīng)用，尤其是高溫泵的密封中。</p><p> 也可采用內(nèi)裝式結(jié)構(gòu).實(shí)際上，引進(jìn)裝置工藝泵的機(jī)械密封絕大部分為內(nèi)裝式密封.輸送危險(xiǎn)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(hù).此外，也可采用彈簧帶有保護(hù)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(hù)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(jìn)裝置所用.的機(jī)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(cè)中都備有不同介質(zhì)所對(duì)應(yīng)的密封型號(hào)選定表.3.對(duì)泄漏的腐蝕性或有毒的介質(zhì)進(jìn)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(biāo)明排放至安全區(qū)域.揚(yáng)子石油化工公司引進(jìn)裝置應(yīng)角的機(jī)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(jī)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(jī)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(huì)在工藝過程中產(chǎn)生結(jié)晶、凝固和反應(yīng)物析出。德州M481釜用機(jī)械密封件。</p><div

稱為環(huán)座）則用普通材料制成。為解決硬質(zhì)合金環(huán)和環(huán)座之間的聯(lián)接和密封，產(chǎn)生了熱裝式、帶密封圈式、焊接和釬焊四種組合式密封環(huán)。帶O型圈的組合式由匐環(huán)結(jié)構(gòu)封環(huán)在硬質(zhì)合金環(huán)與環(huán)座之間用H7／g8的滑動(dòng)配合。在兩者配合圓柱面間置一聚四氟乙烯或合成橡膠制成的O形密封圈，防止其間的密封流體泄漏，且將硬質(zhì)合金環(huán)與環(huán)座組合在一起。在硬質(zhì)合金環(huán)與環(huán)座的平面結(jié)合處設(shè)一銷釘，以傳遞扭矩。此種組合結(jié)構(gòu)，無組合應(yīng)力產(chǎn)生／也無由此引起的組合密封環(huán)的密封端面的變形，但是組合密封環(huán)零件的數(shù)量增加了，還需要在硬質(zhì)合金環(huán)上鉆孔或槽，給制造增加了難度，同時(shí)由于增設(shè)了o形圈，密封環(huán)的使用溫度受到了限制。熱裝式密封環(huán)的結(jié)構(gòu)為提高帶O形圈密封環(huán)的使用溫度，出現(xiàn)了熱裝式密封環(huán)。它是靠硬質(zhì)合金環(huán)和環(huán)座之間的過盈配合來傳遞扭矩并實(shí)現(xiàn)密封，是目前應(yīng)用**多的一種密封環(huán)（圖23）。這種密封環(huán)組合時(shí)將環(huán)座加熱，環(huán)座孔受熱脹大，放入硬質(zhì)合金環(huán)，冷卻之后兩者在過盈下完成組合，再在常溫下研磨和拋光密封端面到要求的精度。這種環(huán)的缺點(diǎn)是，隨著時(shí)間的推移，環(huán)境和使用溫度的變化，密封端面的平面度將發(fā)生變化而不符合要求。究其原因，一是熱裝結(jié)構(gòu)本身存在過盈。鶴壁MR-D釜用機(jī)械密封件。忻州2009釜用機(jī)械密封件</p><p

比YG6大1倍多，為／℃（10～500℃時(shí)）。這兩點(diǎn)決定了耐熱沖擊性能不如YG6好。正因?yàn)榫€膨脹系數(shù)較大，和馬氏體不銹鋼接近（10～500℃時(shí)為11X10-6／℃），為和環(huán)座焊接提供了有利條件。焊接時(shí)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(jīng)1100℃高溫熔焊，然后進(jìn)行回火處理，以消除焊接應(yīng)力。由于是焊接的密封環(huán)，硬質(zhì)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(jià)格較低。這種合金的牌號(hào)為CN15，其中Cr3C285%，Ni為15%，由北京硬質(zhì)合金廠研制成功。熱裝式密封環(huán)以其性能***應(yīng)用，但過盈量過大則硬質(zhì)合金在較大擠壓應(yīng)力作用下產(chǎn)生變形；過盈量過小，使用時(shí)會(huì)松脫。經(jīng)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(zhì)合金環(huán)兩者線膨脹純利系數(shù)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(dāng)，線膨脹系數(shù)太大。確定過盈值應(yīng)遵循的原則：1）從傳遞扭矩的角度考慮過盈值應(yīng)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。銅仁鹽酸釜用機(jī)械密封</p><p
