其抗拉強(qiáng)度和硬度增加而韌性下降.塑料和橡膠的低溫性能比金屬材料更為敏感.一般情況下，塑料和橡膠只能在-50℃以上的溫度范圍使用。對(duì)于低溫泵，資料[13]介紹:丁睛橡膠的使用溫度限為-60℃氯丁橡膠為-65℃，硅酮橡膠為-80℃，氟化橡膠為-45℃，聚四氟乙烯為-79℃，并認(rèn)為使用以上這些材料作填料的機(jī)械密封以-70℃為使用極限。如果介質(zhì)溫度在-70℃以下，則使用波紋管型機(jī)械密封或者雙端面機(jī)械密封.資料[6]介紹聚四氟乙烯在氦的沸點(diǎn)(℃)還能保持一點(diǎn)柔軟性，適宜做低溫材料，哈爾濱管道泵用機(jī)械密封件，但聚四氟乙烯的膨脹系數(shù)大，哈爾濱管道泵用機(jī)械密封件，所以在-50~-100℃溫度使用時(shí)，常采用四氟填充石墨或玻璃纖維，而不用純四氟材料.此外，在低溫時(shí)，V形圈裝到軸套上后，動(dòng)環(huán)往往不能浮動(dòng)。因此，要注意V形圈的組裝尺寸。關(guān)于低溫機(jī)械密封及低溫泵材料如表10-4所示。低溫時(shí)PTFE的機(jī)械性能如表10-5所示。2.結(jié)構(gòu)要求在一般的0~-50℃低溫下，常采用單端面機(jī)械密封，有非平衡或平衡型結(jié)構(gòu)，但多數(shù)選用平衡型結(jié)構(gòu)，這是因?yàn)槊芊舛嗣娴囊盒萁?jīng)摩擦后溫度升高，液膜壓力隨之升高而將密封面推開，泄漏加劇。因此，低溫時(shí)的端面比壓要選高值。在液溫低于-70℃時(shí)，哈爾濱管道泵用機(jī)械密封件，則采用波紋管密封或雙端面密封.不過使用雙端面密封時(shí)。朝陽區(qū)石家莊工業(yè)泵泵用機(jī)械密封件維修。哈爾濱管道泵用機(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(tái)，動(dòng)環(huán)斷面為“L”形，動(dòng)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(dòng)環(huán)泄漏，在動(dòng)環(huán)和軸套凸臺(tái)端面有密封圈。集裝式密封的動(dòng)環(huán)也可用螺帽固定，和前者不同的是動(dòng)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(dòng)（圖38）。動(dòng)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(dòng)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(dòng)環(huán)和軸套之間泄漏。3)頂絲傳動(dòng)（圖39）。這種結(jié)構(gòu)實(shí)際上增加了一個(gè)傳動(dòng)套，該套用頂絲固定在軸上，動(dòng)環(huán)用銷釘與其傳動(dòng)，在傳動(dòng)套和軸以及動(dòng)環(huán)和傳動(dòng)套之間均設(shè)有密封圈。這種動(dòng)環(huán)結(jié)構(gòu)較為復(fù)雜，但其浮動(dòng)性得到了改善。4）銷釘傳動(dòng)（圖40）。該種傳動(dòng)省略了圖39的傳動(dòng)套，動(dòng)環(huán)和軸用銷釘傳動(dòng)，其軸向靠臺(tái)階定位，顯然這種動(dòng)環(huán)和軸沒有剛性聯(lián)接，浮動(dòng)性很好。旋轉(zhuǎn)型機(jī)械密封的靜環(huán)防轉(zhuǎn)方法1）浮動(dòng)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(dòng)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(gè)缺點(diǎn)。欽州凱泉泵用機(jī)械密封件廠寶雞安德里茨泵用機(jī)械密封件維修。</p><div

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。</p><p> 九、波紋管式機(jī)械密封波紋管式機(jī)械密封的應(yīng)用范圍很廣，從低溫到高溫，從中性介質(zhì)到腐蝕性介質(zhì)，從低速到高速，從普通到苛刻的工作條件都可選用。所有這些可通過變更波紋管的幾何形狀（如內(nèi)外徑、波片厚度和波數(shù)等）與材料彈性模量，改變波紋管的彈率。根據(jù)介質(zhì)的腐蝕性能，選用不同的波紋管材料等。例如對(duì)工作壓力和溫度都不高的中性介質(zhì)（油和水等），可選用橡膠制造的簡易波紋管密封；在腐蝕性介質(zhì)中（酸或減等），可選用四氟制造的波紋管密封；高溫和高速下，可采用焊接金屬波紋管機(jī)械密封等。焊接金屬波紋管密封的特點(diǎn)焊接金屬波紋管機(jī)械密封用的波紋管是由軋制的金屬薄板沖裁成環(huán)形波紋狀的型面，波形多采用S形，將許多個(gè)波片重疊起來，分別在環(huán)形的外緣和內(nèi)緣進(jìn)行焊接，組成一個(gè)波紋管，兩端再與傳動(dòng)座和動(dòng)環(huán)焊接成整體。除了不用輔助密封圈外，還具備使用溫度范圍廣的特點(diǎn)，可達(dá)600度，可到一200度。此外高速下對(duì)軸的振動(dòng)和振擺適應(yīng)性較強(qiáng)，有很好的補(bǔ)償能力，保證密封端面良好地貼合。但是長期在高溫下工作的焊接金屬波紋管密封，波紋管的彈率有減小的趨勢(shì)（俗稱“失彈”），使用受到一定的限制。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。寶雞襄樊五二五泵用機(jī)械密封件維修。</p><div

還與軸徑尺寸有關(guān).當(dāng)摩擦副環(huán)基體為不銹鋼、高鎳合金、欽合金時(shí)，熱鑲硬質(zhì)合金的允許使用溫度對(duì)不同軸徑的關(guān)系如圖10-9所示.5.摩擦副環(huán)與軸之間的許用間隙高溫條件下，由于摩擦副環(huán)與軸兩者的熱脹系數(shù)的差異，會(huì)出現(xiàn)摩擦副環(huán)與軸之間間隙趨近于零的現(xiàn)象，因而造成摩擦副環(huán)浮動(dòng)性消失導(dǎo)致密封失效。所以在設(shè)計(jì)時(shí)必須合理和正確選擇摩擦副環(huán)與軸之間的間隙。二、高溫機(jī)械密封實(shí)例1.布格曼公司的HSHF+MFL型密封芳烴裝置循環(huán)油泵GA-102AB.功率1650kW，轉(zhuǎn)速6748r/min,輸送介質(zhì)為汽油，操作溫度262~284度，進(jìn)口壓力，出口壓力~175MPa，機(jī)械密封采用布格曼公司HSHF+MFL混合結(jié)構(gòu)，這是適合高溫、高壓和高速工作條件下的密封。這里HSHF是單端面、流體動(dòng)壓式帶泵效螺旋結(jié)構(gòu)MFL是單端面金屬波紋管結(jié)構(gòu).HSHF和MFL都是彈簧靜止式，以適應(yīng)高速運(yùn)轉(zhuǎn)的要求.該密封從結(jié)構(gòu)上布置成串聯(lián)式，裝于油泵的吸人端和排出端，因HSHF帶有泵效螺旋，它與軸的旋轉(zhuǎn)方向有關(guān).在吸入端的泵效套(12A)是右螺旋，泵效外殼(25A)提左螺旋;在排出端的泵效套(12B)是左螺旋，泵效外殼(25B)是右螺旋，安裝時(shí)按圖上要求裝配不能搞錯(cuò).，圖10-10為HSHF2/103+MFL65/88的結(jié)構(gòu)圖.。韶關(guān)襄陽五二五泵用機(jī)械密封件維修。哈爾濱管道泵用機(jī)械密封件</p><p

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機(jī)械密封傳動(dòng)座和動(dòng)環(huán)的傳動(dòng)方式1）銷釘傳動(dòng)。通過推環(huán)，在推環(huán)和動(dòng)環(huán)之間用銷釘實(shí)現(xiàn)傳動(dòng)（圖35），這種傳動(dòng)方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動(dòng)。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動(dòng)環(huán)外緣制成圓弧槽，而將與此接觸的傳動(dòng)座壓成突耳，使之嵌入動(dòng)環(huán)的槽中，實(shí)現(xiàn)傳動(dòng)（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(dòng)。傳動(dòng)座與彈簧以及彈簧和動(dòng)環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實(shí)現(xiàn)傳動(dòng)（圖34），當(dāng)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(dòng)。為了增加并圈彈簧傳動(dòng)的可靠性，彈簧的兩個(gè)端頭制成彎勾形，分別鉤住傳動(dòng)座和動(dòng)環(huán)（圖36）。5）離合器傳動(dòng)。傳動(dòng)座和動(dòng)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(shí)現(xiàn)傳動(dòng)（圖37）。6）波紋管傳動(dòng)。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(dòng)座和動(dòng)環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對(duì)金屬波紋管，則采用焊接；對(duì)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(jī)械密封的動(dòng)環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動(dòng)環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。哈爾濱管道泵用機(jī)械密封件</p><p
