可防止意外的損壞。這些優(yōu)點也意味著可縮減密封的維修和更換時間。各種彈筒式密封幾乎都可以在市場上購得，因此可以減少使用中出現(xiàn)的風(fēng)險因素，而且還可以節(jié)約使用普通密封件所固有的維修時間。雙重密封和液體阻隔裝置采用雙重密封面的密封來代替單一的密封件具有更高程度的防漏特性。這類雙重密封大都應(yīng)用于揮發(fā)性強、有毒、易致*、危險和潤滑性很差的液體。雙重密封一般有三種設(shè)計型式，每種型式都要求在雙重密封面之間使用一種液體阻隔系統(tǒng)，以防止液體或氣體外泄。比較常用的低成本雙重密封是一種以背靠背方式安裝的密封，其旋轉(zhuǎn)密封面以相反的方向排列。它往往需要一種阻隔液體，其壓力應(yīng)高于填料盒壓力，大約為20psi，這樣就可保證內(nèi)部的密封始終能得到阻隔液體的潤滑，而且也可保證密封面達(dá)到一定的密封壓力。圖5這類密封的旋轉(zhuǎn)面采用面對面方式進(jìn)行安裝，并采用高壓或低壓阻隔液體系統(tǒng)。在結(jié)構(gòu)比較復(fù)雜的面對面型式密封中，旋轉(zhuǎn)密封面之間是以面對面方式排列的(見圖5)，ZF40-2315機械密封，ZF40-2315機械密封，它們往往在同一靜止密封面的相反方向上動作。這類密封既可采用高壓阻隔液體系統(tǒng)，也可采用低壓阻隔液體系統(tǒng)，ZF40-2315機械密封。第三種設(shè)計型式的密封采用串行式排列方式，即兩個旋轉(zhuǎn)密封面都離開葉輪。合肥YM109機械密封件。ZF40-2315機械密封</p><div

以及機械密封的平衡程度，還有密封端面液膜的閃蒸等都是造成端面打開而使固體顆粒進(jìn)入的主要原因。c）機械密封的平衡程度β也影響著密封的磨損。一般情況下，平衡程度β=75%左右適宜。β<75%，磨損量雖然降低，但泄漏增加，密封面打開的可能性增大。對于高負(fù)荷（高PV值）的機械密封，由于端面摩擦熱較大，β一般取65%～70%為宜，對低沸點的烴類介質(zhì)等，由于溫度對介質(zhì)氣化較敏感，為減少摩擦熱的影響，β取80%～85%為好。7、因安裝、運轉(zhuǎn)或設(shè)備本身所產(chǎn)生的誤差而造成機械密封泄漏a）由于安裝不良，造成機械密封泄漏。主要表現(xiàn)在以下幾方面：1）動、靜環(huán)接觸表面不平，安裝時碰傷、損壞；2）動、靜環(huán)密封圈尺寸有誤、損壞或未被壓緊；3）動、靜環(huán)表面有異物；4）動、靜環(huán)V型密封圈方向裝反，或安裝時反邊；5）軸套處泄漏，密封圈未裝或壓緊力不夠；6）彈簧力不均勻，單彈簧不垂直，多彈簧長短不一；7）密封腔端面與軸垂直度不夠；8）軸套上密封圈活動處有腐蝕點。b）設(shè)備在運轉(zhuǎn)中，機械密封發(fā)生泄漏的原因主要有：1）泵葉輪軸向竄動量超過標(biāo)準(zhǔn)，轉(zhuǎn)軸發(fā)生周期性振動及工藝操作不穩(wěn)定，密封腔內(nèi)壓力經(jīng)常變化等均會導(dǎo)致密封周期性泄漏。機械密封KCC40-25-250亳州109-55機械密封件。</p><div

管線必須經(jīng)過清洗，防止堵塞，這點對于新裝置尤為重要.因為雜質(zhì)常從管線進(jìn)人密封處影響密封性能，整個系統(tǒng)要排空，防止密封腔高處形成氣塞，導(dǎo)致干摩擦運行.2.啟動前要進(jìn)行靜壓試驗，試驗壓力同工作壓力;檢查機械密封本身及有關(guān)的密封點和接頭處有無泄漏，如有泄漏應(yīng)設(shè)法處理.3.按泵的旋轉(zhuǎn)方向盤車，合乎要求后才能交付使用.二、啟動運轉(zhuǎn)1.主機啟動之前，應(yīng)保持密封腔內(nèi)充滿液體或被密封的介質(zhì)，如有單獨輔助密封系統(tǒng)應(yīng)先啟動，冷卻水系統(tǒng)亦須開始流通(停車時停止);對于輸送凝固的介質(zhì)或粘度很大的介質(zhì)，應(yīng)用蒸汽將密封腔加熱便介質(zhì)熔化.啟動前必須盤車，以防突然啟動而造成軟環(huán)破裂.2.正常使用前先進(jìn)行常琢運轉(zhuǎn)，觀察密封部位的溫升是否正常.如有輕徽泄漏，可跑合一段時間，使端面貼合更加均勻，直到泄漏童逐漸減少至正常為止.如運轉(zhuǎn)1~3小時泄漏量仍不減少，則需停車檢查.3.升壓、升溫運轉(zhuǎn):經(jīng)過常壓運轉(zhuǎn)考驗的機械密封應(yīng)及時做與操作條件相同的升壓、升溫運轉(zhuǎn).升壓、升溫可分別進(jìn)行.升的過程應(yīng)緩慢，注意升壓(或升溫)過程中可能發(fā)生的變化，如機件有無碰撞，端面是否脫開，摩擦發(fā)熱是否過快，防轉(zhuǎn)銷有無脫開或損壞，壓力是否穩(wěn)定。</p><p> 如油渣泵、回?zé)捰捅?、常減壓塔底泵等常見的失效現(xiàn)象。在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)進(jìn)入密封面、抽空等情況下，都會導(dǎo)致環(huán)面出現(xiàn)徑向裂紋；b）石墨炭化是使用碳-石墨環(huán)時密封失效的主要原因之一。由于在使用中，如果石墨環(huán)一旦超過許用溫度（一般在-105～250℃）時，其表面會析出樹脂，摩擦面附近樹脂會發(fā)生炭化，當(dāng)有粘結(jié)劑時，會發(fā)泡軟化，使密封面泄漏增加，密封失效；c）輔助密封件（如氟橡膠、乙丙橡膠、全橡膠）在超過許用溫度后，將會迅速老化、龜裂、變硬失彈?，F(xiàn)在所使用的柔性石墨耐高溫、耐腐蝕性較好，但其回彈性差。而且易脆裂，安裝時容易損壞。6、由于密封端面的磨損而造成的密封失效a）摩擦副所用的材料耐磨性差、摩擦系數(shù)大、端面比壓（包括彈簧比壓）過大等,都會縮短機械密封的使用壽命。對常用的材料，按耐磨性排列的次序為：碳化硅-碳石墨、硬質(zhì)合金-碳石墨、陶瓷-碳石墨、噴涂陶瓷--碳石墨、氮化硅陶瓷--碳石墨、高速鋼--碳石墨、堆焊硬質(zhì)合金--碳石墨。b）對于含有固體顆粒介質(zhì)，密封面進(jìn)入固體顆粒是導(dǎo)致使密封失效的主要原因。固體顆粒進(jìn)入摩擦副端面起研磨劑作用，使密封發(fā)生劇烈磨損而失效。密封面合理的間隙。南通109-20機械密封件。</p><div

以及汽水分離口的狀況。17方案：外部排液管道布置是，用浮子液位開關(guān)測量密封泄漏量，對高泄漏量進(jìn)行報警，液位開關(guān)下游的孔板，其孔徑通常為5mm，設(shè)置在立管腿上。機封在大氣端，帶泄漏檢查的外部排水，原因：單獨使用或與62方案一起使用，用于間隙很小的節(jié)流襯套，用于外部場所的單端面機封，場合：流程泄漏或冷卻流體的泄漏收集，主機封的安全指示儀。維護(hù)：排水口必須在壓蓋底部，管路是向下傾斜的。持續(xù)向液體回收系統(tǒng)排水，在液位開關(guān)下游的限流孔板（一般為1/4）必須是垂直方向，從溢流腔出來旁通管，必須再進(jìn)入限流孔板下面。當(dāng)用固化流體時，管路可能要加熱，經(jīng)常檢查、查看閥門是否關(guān)閉，管路是否阻塞，液位開關(guān)是否正常工作。18方案：非承壓緩釋器氣體控制系統(tǒng)，安全密封通常采用氮氣作為緩沖氣體。錫山區(qū)波紋管機械密封件。60SV35M-6.03機械密封</p><p

特別要注意彈簧的旋向，其旋向應(yīng)與軸轉(zhuǎn)動方向相同，使彈簧越旋越緊，就是按定出的軸旋轉(zhuǎn)方向，從靜環(huán)朝動環(huán)方向看，順時針方向需要右旋彈簧，逆時針方向則要左旋彈簧.使用小彈簧時，要檢查各組彈簧的圈數(shù)和自由高度;6.對安裝機械密封的主機按技術(shù)要求檢查軸向串量、徑向跳動、有關(guān)的垂直度、同心度、表面粗糙度、配合尺寸和對泵的聯(lián)軸節(jié)要求等.(1)軸向串量:要求不超過，一般在，軸向串量過大，使機械密封彈簧比壓不穩(wěn)定，引起密封端面過全磨損或泄漏，由于軸的抖動而使密封破損，這在石墨環(huán)更為明顯二此外，因軸向串童過大，還會使機械密封與軸(或軸套)的接觸處局部腐蝕、侵蝕或磨損，在這方面，聚四氛乙烯密封圈因彈性不及橡膠密封圈，其所受影響更大.因此，軸向串量從原要求±，可以減輕因軸向串量過大而引起的危害，另一方面，如軸向串量過小，如低于m時，則對軸承產(chǎn)生不良影響.實際上，軸向串全還與軸的轉(zhuǎn)速有關(guān)，圖9-1是軸向串量允許值與轉(zhuǎn)速關(guān)系，可供安裝時參考。聯(lián)軸節(jié)對中要求的檢查應(yīng)該在所有管線接頭安裝以后進(jìn)行，否則找正工作就不徹底。關(guān)于兩個半聯(lián)軸節(jié)連接后端面間的間晾，可參照有關(guān)規(guī)定，一般端面間隙略大于軸向串量。因為聯(lián)軸節(jié)的種類很多。ZF40-2315機械密封</p><p
