液態(tài)烴泵用機(jī)封液態(tài)烴介質(zhì)是一種低溫液化氣體，具有低沸點(diǎn)、低粘度、高蒸汽壓等特性。在這種工況下應(yīng)用的機(jī)械密封，會(huì)使密封材料出現(xiàn)冷脆性，大氣中的水汽會(huì)在密封裝置的大氣側(cè)面上凍結(jié)，摩擦副端面液膜容易汽化等。尤其是當(dāng)介質(zhì)稍有泄漏，漏出的液態(tài)烴在大氣側(cè)立即汽化，帶走大量熱，機(jī)械密封環(huán)境溫度急劇下降，使用一般的密封材料，如橡膠或聚四氟乙烯普遍變脆，導(dǎo)致密封失效，泄漏增大而不可收拾。有些企業(yè)采用雙端面l機(jī)械密封，在介質(zhì)和大氣端設(shè)一隔離室，其間通以封油以緩和低溫的影響。但這種結(jié)構(gòu)復(fù)雜且需配封液系統(tǒng)。據(jù)經(jīng)驗(yàn)，使用波紋管機(jī)械密封比較好，主要表現(xiàn)在用屬波紋管和柔性石墨代并輔助密封圈，解決了密封圈材料發(fā)生冷脆而失彈及緩沖作用的問題，如DBM型、YH604/606/609型等。a)金屬波紋管材料選用耐低溫、塑性及韌性好的哈-C,AM350，Carpenter20等;b)摩擦副l材料在兩種特殊情況下選用:1)對連續(xù)運(yùn)轉(zhuǎn)的設(shè)備，介質(zhì)內(nèi)若含較多的固體顆粒，此時(shí)選用“硬對硬”結(jié)構(gòu)(在實(shí)際中選了YG6-YG6)較好，一般連續(xù)運(yùn)轉(zhuǎn)壽命8000h以上;2)對間歇性的運(yùn)轉(zhuǎn)一設(shè)備，摩擦副選用碳化鎢或碳化硅對特種石墨。c）由于在低溫條件一下，摩擦副端面的汽化對機(jī)械密封，性能影響很大。順義區(qū)JCS2A-115安德里茲泵用機(jī)械密封薊州區(qū)11-LP-D-S32-D20/50-DE安德里茲泵用機(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(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(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)。順義區(qū)JCS2A-115安德里茲泵用機(jī)械密封</p></p><br
