摘要：結(jié)合設(shè)計經(jīng)驗以及對API682標準的研究，對泵用機械密封的選型要點進行了分析，主要包括密封類型、密封形式、布置方式、沖洗方案等。進而對煉油裝置中的高溫熱油泵、高溫熱水泵以及強酸強堿泵機械密封及輔助系統(tǒng)的選型提出了合理化建議，對API682中的PLAN53B和PLAN23進行了改進，使之更好地為機械密封服務(wù)，有利于機械密封長期穩(wěn)定運行。由于機械密封具有密封性能好、工作可靠、泄漏量小、功率消耗少等特點，因而在國內(nèi)外煉油化工生產(chǎn)的旋轉(zhuǎn)設(shè)備中得到了***的應(yīng)用，已經(jīng)成為泵、壓縮機、反應(yīng)釜、攪拌器等工藝設(shè)備能否正常運轉(zhuǎn)的關(guān)鍵部件。隨著環(huán)境保護和人類健康要求的提高，煉油裝置中對泵用機械密封的要求也在不斷提高。據(jù)統(tǒng)計，煉油裝置中機泵故障的40%以上是由于機械密封發(fā)生泄漏而引起的，青島11-LP-D-S32-D20/50-DE安德里茲泵用機械密封。造成這一現(xiàn)象的原因，一是作為機泵中的動密封其本身所處的工作條件、起的作用所決定；二是許多國內(nèi)設(shè)計單位以及工程公司認為機械密封及系統(tǒng)的選用是泵廠和密封廠的責任，往往對密封的類型、布置方式、沖洗方案了解不深，難以制定機械密封的選配方案，造成部分密封選型不當，青島11-LP-D-S32-D20/50-DE安德里茲泵用機械密封。在密封方案的選擇中，除了密封本身安全可靠的設(shè)計外，青島11-LP-D-S32-D20/50-DE安德里茲泵用機械密封，密封的工作環(huán)境對密封壽命的影響更加重要。哈爾濱11-LP-D-S32-D20/50-DE安德里茲泵用機械密封。青島11-LP-D-S32-D20/50-DE安德里茲泵用機械密封</p><div

見“27”）。只有在特殊情況下，如介質(zhì)中含有固體顆粒、有結(jié)晶析出或高粘度流體中才選用硬對硬的配對。當選用一軟一硬的配對時硬環(huán)端面的寬度比軟環(huán)寬，在硬對硬的材質(zhì)中可不受此限制。為減少泄漏量和機械雜質(zhì)進入密封端面的可能性，盡量采用內(nèi)裝內(nèi)流式密封結(jié)構(gòu)S選擇導熱性良好的材料做動環(huán)，以散出較多的熱量，降低密封端面的溫度。為保證密封環(huán)的整體強度和剛度，環(huán)的壁厚不可太薄。對于導熱性良好的材料，增加環(huán)厚有利散熱；對于導熱性欠佳的材料厚度可小些。對于所受壓力較高的密封環(huán)，要從力學角度另行設(shè)計，必要時采取加固措施。環(huán)的形狀要軸對稱，以減少其不對稱的機械變形和熱變形。動環(huán)做補償環(huán)時，例如國產(chǎn)104和B104型密封（圖13、圖14），動環(huán)和軸（軸套）的（直徑）間隙為0．40～0．60mm，以防止動環(huán)在工作中卡住而失去補償能力；靜環(huán)內(nèi)徑要比軸（軸套）大l～2mm，避免兩者摩擦。密封端面的寬度是個重要參數(shù)，要綜合考慮。三、密封端面的寬度要考慮的因素密封端面的寬度一般是首先決定軟面的寬度，硬面寬度自不待說。泄漏量與端面寬度關(guān)系不大。但是，從產(chǎn)生的摩擦熱量來說窄一些較好，產(chǎn)生的熱量較少，溫度梯度小，熱變形也小，磨損較均勻。青島11-LP-D-S32-D20/50-DE安德里茲泵用機械密封11-LP-D/110-00

液態(tài)烴泵用機封液態(tài)烴介質(zhì)是一種低溫液化氣體，具有低沸點、低粘度、高蒸汽壓等特性。在這種工況下應(yīng)用的機械密封，會使密封材料出現(xiàn)冷脆性，大氣中的水汽會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)復雜且需配封液系統(tǒng)。據(jù)經(jīng)驗，使用波紋管機械密封比較好，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)運轉(zhuǎn)的設(shè)備，介質(zhì)內(nèi)若含較多的固體顆粒，此時選用“硬對硬”結(jié)構(gòu)(在實際中選了YG6-YG6)較好，一般連續(xù)運轉(zhuǎn)壽命8000h以上;2)對間歇性的運轉(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械密封，性能影響很大。</p><p>

沖洗液的流量、壓力不夠，沖洗口位置設(shè)計不合理等原因，也同樣達不到效果。常用的措施有：1.在條件允許的情況下，盡量設(shè)計輔助沖洗系統(tǒng)。沖洗壓力一般要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力等因素來計算。軸封腔壓力很高或者壓力幾乎接近該密封使用極限時，也可由密封腔引液體至低壓區(qū)，使軸封液體流動以帶走摩擦熱。2.根據(jù)每種泵的操作條件，合理地配置管路和附件。如冷卻器、孔板、過濾器、閥門、流量指示器、壓力表、溫度等。實際上密封的可靠性和壽命，在很大程度上取決于密封輔助系統(tǒng)的配置，另外泵軸、軸套、泵體、密封腔體的加工精度不夠等原因的存在對機械密封的密封效果也是很不利的，在這些方面應(yīng)該做到嚴格把關(guān)。（四）振動偏大及消除措施機械密封振動偏大往往不是機械密封自身的原因，而是泵軸設(shè)計不合理、加工精度不夠、靠背輪的平行度偏大、徑向力大等原因，消除泵振動措施有：泵、電機、底座、現(xiàn)場管路等輔助設(shè)備在現(xiàn)場安裝時，要嚴格把關(guān)，消除振動源。（五）泵氣蝕的原因及改進措施離心泵葉輪入口處是泵內(nèi)壓力小的地方，當此處的壓力等于或低于工作溫度下被輸送液體的飽和蒸汽壓1pt時，液體就會沸騰汽化，產(chǎn)生大量氣泡。河東區(qū)11-LP-D-S32-D20/40-DE安德里茲泵用機械密封。貴陽安德里茲泵用機械密封SAF-55-QREG-304449</p><p

在有的國家已成為主要的軸封方式。國內(nèi)的焊接金屬波紋管密封質(zhì)量不夠穩(wěn)定，其主要原因是制造金屬波紋管的材料欠佳，大都用181型不銹鋼制造。這種材料耐腐蝕，但強度和彈性較差，特別是在高溫下，使用一段時間后出現(xiàn)“失彈”。國外大都用AM350制造，這是一種沉淀硬化不銹鋼，高溫下仍有足夠的強度和彈性，先彈的機會較少。但是，經(jīng)過長期使約后也暴露了一些缺陷，在波片的焊縫附近開裂。究其原因是在受壓狀態(tài)下。一軸向斷面上各處應(yīng)力分布不均勻，有較嚴重的應(yīng)力集中現(xiàn)象，從而降低了使用壽命?，F(xiàn)有的焊接金屬波紋管其斷面的內(nèi)外緣處（或稱波谷和波峰）、幾何形狀和尺寸是相同的，故也稱為“對稱型”波紋管。它具有上述缺陷，為克服此缺陷，出現(xiàn)了“非對稱型”波紋管。所謂非對稱型波紋管是波谷（內(nèi)緣處）和波峰（外緣處）購肉率半徑不同，波峰大于波谷。在介質(zhì)壓力作用下，迫使其向低壓側(cè)變形，工作時斷面形狀趨于對稱，應(yīng)力趨于均勻（圖44）。同時由于采用了特殊結(jié)構(gòu)的波紋管，焊縫長度**縮短。據(jù)國外資料介紹一種13/4英寸的T15WTO型密封，焊縫總長度超過4000mm，而同樣尺寸的非對稱型波紋管密封，焊縫長度*87mm，使密封的可靠性**提高，密封能力提高30%。青島11-LP-D-S32-D20/50-DE安德里茲泵用機械密封</p><p
