為了使密封面之間始終保持互相配合，彈簧起到了機(jī)械密封與運(yùn)動(dòng)主軸之間的恒定調(diào)節(jié)作用。當(dāng)旋轉(zhuǎn)面和主軸之間采用人造橡膠密封時(shí)，該彈性體就會(huì)在主軸上來回運(yùn)動(dòng)。這種重復(fù)摩擦動(dòng)作，會(huì)磨蝕主軸上的防腐材料，失去主軸的氧化膜保護(hù)層，**終會(huì)在主軸的摩擦面上形成磨損溝槽，造成液體從溝槽中泄漏，并增加必要的維修工作量或甚至更換主軸。為了解決這一問題，一般在填料盒內(nèi)安裝一個(gè)可更換的軸套。

隨著時(shí)代的高速發(fā)展，對(duì)石油資源的需求量不斷增加，石油煉廠的生產(chǎn)任務(wù)越來越重。泵用機(jī)械在石油煉廠生產(chǎn)過程中發(fā)揮著非常重要的作用，但在其實(shí)際運(yùn)行過程中，其機(jī)械密封往往會(huì)出現(xiàn)各種問題，不僅影響機(jī)械的正常使用，還容易導(dǎo)致安全問題的發(fā)生。文章對(duì)石油煉廠常用機(jī)械密封的設(shè)計(jì)改進(jìn)與應(yīng)用進(jìn)行分析，希望對(duì)中國(guó)石油煉化事業(yè)的發(fā)展起到積極的促進(jìn)作用。 </p> <p> 機(jī)械密封在流體機(jī)械中發(fā)揮著非常重要的作用，可以有效防止機(jī)械內(nèi)部的介質(zhì)流出泵外。其運(yùn)行情況，對(duì)泵用機(jī)械運(yùn)行的穩(wěn)定性有著非常直接的影響，在石油煉化生產(chǎn)過程中，發(fā)揮著非常重要的作用。各種流體機(jī)械在化工生產(chǎn)中，有著非常明顯的應(yīng)用，隨著石油煉化技術(shù)的高速發(fā)展，流體機(jī)械的應(yīng)用參數(shù)水平也在不斷提高，對(duì)機(jī)械性能要求也在不斷提高，轉(zhuǎn)軸密封的作用非常突出。我國(guó)對(duì)機(jī)械密封的研究開始較晚，從上個(gè)世紀(jì)80 年代，機(jī)械密封在石油煉化產(chǎn)業(yè)中才開始得到大規(guī)模的應(yīng)用。 </p><p> 水泵出現(xiàn)滲水的部位主要是兩個(gè)部分，一是水泵的軸承密封件，一般此處漏是從水泵的溢流孔流出，此時(shí)需要更換水泵；二是水泵的也發(fā)動(dòng)機(jī)結(jié)合部件的密封件，這里可以單獨(dú)更換此零件（提醒大家要注意避免“小病大治”）。 </p> <p> 水泵滲漏的原因：由于水泵設(shè)計(jì)原因，水泵軸承收到側(cè)面單邊力量過大，也就是皮帶輪側(cè)偏心力大，容易導(dǎo)致水泵軸承偏磨；加之大家平時(shí)急加速的和急收油等加速皮帶對(duì)水泵軸承的沖擊（這是從用的角度出發(fā)）；內(nèi)部缺水，水泵軸承得不到冷卻液的潤(rùn)滑，也會(huì)導(dǎo)致密封件損壞（這是從養(yǎng)的角度出發(fā)）；防凍液長(zhǎng)時(shí)間不更換，雜質(zhì)增加加速磨損（同樣也是養(yǎng)的問題）；針對(duì)密封實(shí)際應(yīng)用中出現(xiàn)的問題，應(yīng)引起重視，分析問題發(fā)生的原因，然后及時(shí)采取針對(duì)性的措施，保證效果。</p><div

選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動(dòng)環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動(dòng)環(huán)和動(dòng)環(huán)座的連接松動(dòng)。 </p> <p> 選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動(dòng)環(huán)輔助密封圈，不需要克服動(dòng)環(huán)補(bǔ)償時(shí)與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯(cuò)的效果。 </p> <p> <br

旋轉(zhuǎn)波紋管密封在旋轉(zhuǎn)離心力作用下可以自身清洗波紋管，減少波紋管**沉積和內(nèi)側(cè)結(jié)焦，并能防止因急冷造成的波紋管變形。泵類設(shè)備轉(zhuǎn)速一般為2950r/min，機(jī)械密封線速度遠(yuǎn)小于25m/s,因此，可以選用旋轉(zhuǎn)結(jié)構(gòu)。 </p> <p> 密封結(jié)構(gòu)形式采用開槽斜面擠緊軸套 </p> <p> 這種定位傳動(dòng)可靠，安裝拆卸方便且不傷軸。并設(shè)置有限位板，便于泵外調(diào)整密封的壓縮量。波紋管內(nèi)徑一處設(shè)一45℃斜角，以分散應(yīng)力，延長(zhǎng)波紋管壽命。輔助密封采用柔性石墨替代合成橡膠，可以承受高達(dá)425℃的高溫。 </p> <p> 摩擦副材料的選取 </p> <p> 對(duì)摩擦副材料的選取我們采用“硬對(duì)硬”結(jié)構(gòu)，起初動(dòng)靜環(huán)我們選擇了SiC-WC，但是運(yùn)轉(zhuǎn)一段時(shí)間發(fā)現(xiàn)動(dòng)環(huán)出現(xiàn)肯邊現(xiàn)象。改用YG6-YG6之后，設(shè)備運(yùn)轉(zhuǎn)一直正常。 </p> <p> <br
