機(jī)泵裝置中，機(jī)動設(shè)備的機(jī)械密封約占整個動密封數(shù)量的80%-85%。而在機(jī)泵故障中，機(jī)械密封的故障大約占整個維修工作量的一半?？梢姍C(jī)械密封在機(jī)泵維修中所占的位置。由于機(jī)泵所輸送的介質(zhì)千差萬別，工藝條件各不相同，所以了解這些情況對機(jī)封的選擇及維護(hù)很重要。結(jié)合多年來在機(jī)封選擇和維修中的經(jīng)驗，介紹幾種特殊工況下機(jī)械密封的工作特點和注意事項。一、高溫下的機(jī)械密封一般情況下，介質(zhì)的溫度超過120℃即認(rèn)為是高溫密封。此時機(jī)械密封存在的主要問題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長時間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。為保證機(jī)械密封在高溫環(huán)境下正常工作，可以采取如下措施。1．給機(jī)封增加冷卻沖洗裝置。2．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。朔州外裝式泵用機(jī)械密封天水循環(huán)泵用機(jī)械密封選型。</p><div

要將軸封部分的溫度設(shè)計為0℃，這時用作氣體密封，密封圈可用普通O形或V形密封圈。密封結(jié)構(gòu)是與泵體結(jié)構(gòu)相適應(yīng)，常用的低溫泵采用立式結(jié)構(gòu).3.輔助裝置(1)要盡可能加大沖洗量，加強(qiáng)冷卻措施，或提高密封腔內(nèi)壓力，來控制液溫升高所引起的氣化現(xiàn)象，要***避免從泵出口端裝沖洗管線來沖洗密封端面，因為在低溫下，這種沖洗管線內(nèi)液體會氣化.所以，一般采逆流沖洗方式.(2)防止單端面密封在泵停轉(zhuǎn)過程中大氣中水分與密封接觸使邊緣結(jié)冰，可用甲醇等化冰劑加以溶解，阻封部分也可通人氮氣干氣加以保護(hù).總之，既要充分冷卻又要采取保冷措施。(3)在高于密封面的部位裝設(shè)排氣管線，這樣，如果產(chǎn)生氣體也可從排氣管線逸出。有關(guān)低溫泵的輔助裝置見第七節(jié)低溫泵輔助系統(tǒng)。二、低溫甲烷泵機(jī)械密封低溫泵通常是立式結(jié)構(gòu)，密封腔設(shè)在泵的上部，密封結(jié)構(gòu)為雙端面平衡型機(jī)械密封。低溫泵的結(jié)構(gòu)及布置如圖10-19所示。1.低溫泵的結(jié)構(gòu)特點(1)筒形結(jié)構(gòu)，不必?fù)?dān)心低溫時發(fā)生變形.(2)一級葉輪位于底部，通過增減柱形筒體的長度(圖10-19中的葉輪只列出二級，實際有十多級)，.來適應(yīng)葉輪級數(shù)的變化。(3)液體從上向下進(jìn)人葉輪，由吸人端排氣從而起到有效的氣體分離器作用。(4)立式結(jié)構(gòu)排氣順暢。</p><p> 西德EKATO公司的RD13、RD23、RD200ST和日本炭研精工的2K07T型都是上裝式密封，它們用于PTA、聚乙烯和聚丙烯裝置.上裝式釜用機(jī)械密封的典型結(jié)構(gòu)如圖10-1所示，這是EKATO公司RD200ST型釜用密封的結(jié)構(gòu)圖.這種密封是雙端面帶水冷來套的密封結(jié)構(gòu)，適用操作溫度為130~180℃.如果操作溫度在130℃以下，可以不用水冷夾套，而用上部冷卻風(fēng)扇(圖3-38)，當(dāng)操作溫度至300~400℃時，必須采用底部帶法蘭冷卻器(圖10-2)的結(jié)構(gòu)，這里法蘭冷卻器起了熱阻擋層的作用.在安裝冷卻水管線時，要注意冷卻水出口管線與漏斗間高度至少在200mm以上，出口處水的溫度應(yīng)低于40~50℃。有關(guān)釜用密封的密封液貯罐及壓力平衡裝置見第七章第二節(jié)壓力裝置.聚丙烯裝置第1號、2號反應(yīng)釜用攪拌器的機(jī)械密封如圖10-3所示.三、底裝式釜用機(jī)械密封反應(yīng)釜底部傳動的攪拌器用的機(jī)械密封是一種特殊結(jié)構(gòu)，因為密封上部要與產(chǎn)品接觸，所以工作條件更為苛刻.底裝式釜用機(jī)械密封的要求:1.在結(jié)構(gòu)上做到不使攪拌釜內(nèi)沉積在底部的固體介質(zhì)與機(jī)械密封相接觸;2.當(dāng)密封失效時，不必排除釜內(nèi)液休也能卸除機(jī)械密封進(jìn)行維修工作，能快速更換，并能在反應(yīng)釜帶壓下進(jìn)行更換機(jī)械密封，還要求在不拆除笨重的傳動機(jī)構(gòu)情況下。貴州福斯泵用機(jī)械密封泄露。</p><div

當(dāng)產(chǎn)生抽空（汽蝕）時，靜環(huán)能離位，從而損壞密封。2）固定型靜環(huán)。圖21所示為幾種固定型靜環(huán)，這種靜環(huán)由于浮動性差，安裝時尤其要注意密封端面和軸心線的垂直度。其優(yōu)點是泵抽空時靜環(huán)不至于離位，較為可靠。3）粘結(jié)型靜環(huán)。上兩種靜環(huán)安裝在壓蓋中時都設(shè)有密封圈，而粘結(jié)型靜環(huán)則取消了密封圈，靜環(huán)與壓蓋之間的密封和防轉(zhuǎn)，用粘結(jié)劑實現(xiàn)。由于采用了粘結(jié)劑，使用溫度和介質(zhì)受到了粘結(jié)劑性能的限制，盡管如此，仍在很多場合得到應(yīng)用。集裝式密封的軸套的傳動普通機(jī)械密封的軸套都是事先安裝和固定在軸上后再安裝機(jī)械密封，而集裝式密封則不同，它是將密封軸套和壓蓋預(yù)先裝在軸套上，再整體向軸上安裝，于是存在一個軸套如何固定在軸上，并傳遞扭矩的問題，同時還要解決軸套和軸之間的泄漏問題。圖42a表示了一種傳動方式。螺釘安裝在零件A上，在軸套的對應(yīng)部位開有圓孔，將螺釘通過軸套的圓孔，并旋緊在軸上，即可實現(xiàn)軸套和軸的傳動。軸套和軸的密封，靠O形圈來完成。這種傳動方式比較簡單。圖42b是另一種傳動方式。它用圓螺母A壓緊軸和軸套之間的填料（四氟制成），靠填料與軸的摩擦力來傳動，同時也起到了密封圈的作用。圖木舒克循環(huán)泵用機(jī)械密封選型。朔州外裝式泵用機(jī)械密封</p><p

比YG6大1倍多，為／℃（10～500℃時）。這兩點決定了耐熱沖擊性能不如YG6好。正因為線膨脹系數(shù)較大，和馬氏體不銹鋼接近（10～500℃時為11X10-6／℃），為和環(huán)座焊接提供了有利條件。焊接時需在環(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，價格較低。這種合金的牌號為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，使用時會松脫。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。石家莊集裝式泵用機(jī)械密封</p><p
