氣體不會在泵的中部滯留·(5)無軸的彎曲問題，軸封可遠(yuǎn)離泵體，減少熱的影響。電機(jī)安裝架為遮風(fēng)結(jié)構(gòu)，所以電機(jī)的溫升對泵幾乎沒有影響。(6)泵殼埋于地下，易于保冷.所以，石油液化氣用的低溫泵常用以上這種結(jié)構(gòu).2.低溫甲烷泵機(jī)械密封甲烷液化氣在-99℃時的蒸汽壓接近3MPa.乙烯裝置脫甲烷塔底泵在-53℃時出口壓力近似3MPa，采用雙端面串聯(lián)式機(jī)械密封，它是比拉公司BB81-K7+BB81B-S7型，尺寸為45x39與50x45(圖10-20)。耐腐蝕機(jī)械密封在腐蝕性介質(zhì)中，機(jī)械密封的零件受到介質(zhì)的強(qiáng)烈侵蝕，摩擦面同時受到.腐蝕和磨損，這種現(xiàn)象稱為“磨蝕“，其腐蝕速度約為無摩擦?xí)r的10~50倍.某些結(jié)構(gòu)材料具有優(yōu)良的耐蝕性能，耐磨性能卻較差;而另一些結(jié)構(gòu)材料雖具有良好的耐磨性，耐蝕性卻很差.因此，摩擦副應(yīng)選擇既要耐腐蝕又要耐磨，輔助密封圈、彈擠和結(jié)構(gòu)件也要有良好的耐蝕性能.在設(shè)計(jì)耐腐蝕機(jī)械密封時，一般采取以下一些措施:1，煙臺222型釜用機(jī)械密封，煙臺222型釜用機(jī)械密封.結(jié)構(gòu)上的隔離措施采用外裝式結(jié)構(gòu)，經(jīng)過適當(dāng)?shù)倪x擇，外裝式密封可以做到無金屬件與工藝介質(zhì)接觸，小的零件如彈簧，煙臺222型釜用機(jī)械密封、銷子可不受工藝介質(zhì)腐蝕.外裝式有普通型機(jī)械密封和波紋管型機(jī)械密封兩種，’以波紋管型密封結(jié)構(gòu)較好(圖10-21).如密封件材質(zhì)耐蝕能力許可。德州212釜用機(jī)械密封件。煙臺222型釜用機(jī)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(jī)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(shí)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(shí)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(shí)現(xiàn)傳動（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。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(shí)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(jī)械密封的動環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。煙臺222型釜用機(jī)械密封太原212釜用機(jī)械密封廠家。</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，熱鑲硬質(zhì)合金的允許使用溫度對不同軸徑的關(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)浮動性消失導(dǎo)致密封失效。所以在設(shè)計(jì)時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，安裝時按圖上要求裝配不能搞錯.，圖10-10為HSHF2/103+MFL65/88的結(jié)構(gòu)圖.。</p><p> 有時密封介質(zhì)本身就是各種懸浮漿液，這些介質(zhì)中的顆粒對密封起著磨料作用.高粘度介質(zhì)常指粘度大于Pa·s(700cP)的介質(zhì).一、含有磨料介質(zhì)的機(jī)械密封實(shí)際生產(chǎn)中經(jīng)常遇到液一固兩相或氣一固兩相介質(zhì)的密封問題，而機(jī)械密封的大敵是含有固體顆粒的溶液.磨料介質(zhì)包含以下幾種情況:1.處理物料是漿液;2.在機(jī)體和管線內(nèi)有雜質(zhì)混人;3.由于溫度變化有結(jié)晶析出或有凝固物產(chǎn)生;4.在密封端面內(nèi)有溶解物析出;5.由于化學(xué)反應(yīng)有固體物質(zhì)產(chǎn)生;6.由于電化學(xué)作用在密封端面內(nèi)析出和附著金屬物質(zhì).普通單端面機(jī)械密封遇到磨料介質(zhì)時產(chǎn)生下列故璋:1.密封端面早期磨損;2.動環(huán)因間隙阻塞和密封圈摩擦力增大而不能動作;3.密封圈不能起緩沖作用;4.彈簧被雜質(zhì)阻塞不能動作;5.軸不能旋轉(zhuǎn);6.整個密封失效.對含磨料介質(zhì)的密封應(yīng)采取以下措施:1.加強(qiáng)沖洗冷卻措施，防止雜質(zhì)在密封腔內(nèi)淤塞，如單端面密封應(yīng)加注液潤滑，雙端面密封則加阻封液或阻封液和輔助注液合用;2.摩擦副材料選用硬對硬配合，常用硬質(zhì)合金對硬質(zhì)合金(或陶瓷);3.盡童采用大彈簧，減少顆粒阻塞機(jī)會；4.如用波紋管密封代替普通機(jī)械密封，建議用橡膠波紋管和焊接金屬經(jīng)過噴涂或合成橡膠包夜的波紋管，因?yàn)橐话憬饘俨y管對處理砂漿液能力差。秦皇島M461釜用機(jī)械密封廠家。</p><div
