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(huì)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(shí)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(guò)許用溫度（一般在-105～250℃）時(shí)，其表面會(huì)析出樹脂，摩擦面附近樹脂會(huì)發(fā)生炭化，當(dāng)有粘結(jié)劑時(shí)，會(huì)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(guò)許用溫度后，將會(huì)迅速老化、龜裂、變硬失彈。現(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(shí)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(guò)大等,都會(huì)縮短機(jī)械密封的使用壽命。對(duì)常用的材料，按耐磨性排列的次序?yàn)椋禾蓟?碳石墨、硬質(zhì)合金-碳石墨、陶瓷-碳石墨、噴涂陶瓷--碳石墨，濟(jì)寧國(guó)產(chǎn)機(jī)械密封、氮化硅陶瓷--碳石墨、高速鋼--碳石墨，濟(jì)寧國(guó)產(chǎn)機(jī)械密封、堆焊硬質(zhì)合金--碳石墨。b）對(duì)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，濟(jì)寧國(guó)產(chǎn)機(jī)械密封，使密封發(fā)生劇烈磨損而失效。密封面合理的間隙。無(wú)錫輕型機(jī)械密封件。濟(jì)寧國(guó)產(chǎn)機(jī)械密封</p><div

2)、對(duì)安裝機(jī)械密封時(shí)壓縮量過(guò)大，導(dǎo)致摩擦副端面嚴(yán)重磨損、擦傷；3)、動(dòng)環(huán)密封圈過(guò)緊，彈簧無(wú)法調(diào)整動(dòng)環(huán)的軸向浮動(dòng)量；4)、靜環(huán)密封圈過(guò)松，當(dāng)動(dòng)環(huán)軸向浮動(dòng)時(shí)，靜環(huán)脫離靜環(huán)座；5)、工作介質(zhì)中有顆粒狀物質(zhì)，運(yùn)轉(zhuǎn)中進(jìn)人摩擦副，探傷動(dòng)、靜環(huán)密封端面；6)、設(shè)計(jì)選型有誤，密封端面比壓偏低或密封材質(zhì)冷縮性較大等。上述現(xiàn)象在試運(yùn)轉(zhuǎn)中經(jīng)常出現(xiàn)，有時(shí)可以通過(guò)適當(dāng)調(diào)整靜環(huán)座等予以消除，但多數(shù)需要重新拆裝，更換密封。3、由于兩密封端面失去潤(rùn)滑膜而造成的失效a）因端面密封載荷的存在，在密封腔缺乏液體時(shí)啟動(dòng)泵而發(fā)生干摩擦；b）介質(zhì)的低于飽和蒸汽壓力，使得端面液膜發(fā)生閃蒸，喪失潤(rùn)滑；c）如介質(zhì)為易揮發(fā)性產(chǎn)品，在機(jī)械密封冷卻系統(tǒng)出現(xiàn)結(jié)垢或阻塞時(shí)，由于端面摩擦及旋轉(zhuǎn)元件攪拌液體產(chǎn)生熱量而使介質(zhì)的飽和蒸汽壓上升，也造成介質(zhì)壓力低于其飽和蒸汽壓的狀況。4、由于腐蝕而引起的機(jī)械密封失效a）密封面點(diǎn)蝕，甚至穿透。b）由于碳化鎢環(huán)與不銹鋼座等焊接，使用中不銹鋼座易產(chǎn)生晶間腐蝕；c）焊接金屬波紋管、彈簧等在應(yīng)力與介質(zhì)腐蝕的共同作用下易發(fā)生破裂。5、由于高溫效應(yīng)而產(chǎn)生的機(jī)械密封失效a）熱裂是高溫油泵。煙臺(tái)常規(guī)機(jī)械密封新吳區(qū)波紋管機(jī)械密封件。</p><div

機(jī)械密封安裝一、安裝前的準(zhǔn)備工作和注意事項(xiàng)1.從包裝箱中取出要安裝的機(jī)械密封放在干凈的平面上，保護(hù)好密封面，并將所有標(biāo)簽、證件整理后待檢;2.檢查機(jī)械密封的型號(hào)、規(guī)格和材質(zhì)證明，零件的數(shù)量，動(dòng)、靜環(huán)配對(duì)是否符合圖紙要求，零件上有無(wú)制造廠的識(shí)別標(biāo)記;3.檢查各零件的表面質(zhì)t，特別是動(dòng)、靜環(huán)的密封端面有無(wú)碰傷、劃痕，如有損壞，必須進(jìn)行修復(fù)或更換，零件表面必須清洗干凈，在動(dòng)、靜環(huán)密封端面上涂一層油;4.檢查石墨環(huán)、城充聚四氛乙烯壞及組裝的動(dòng)、靜環(huán)的水壓試驗(yàn)證明，如果沒有試壓證明，安裝前要補(bǔ)做水壓試驗(yàn)，試驗(yàn)壓力照第六章***節(jié)規(guī)定;5.并圈彈簧傳動(dòng)的機(jī)械密封，特別要注意彈簧的旋向，其旋向應(yīng)與軸轉(zhuǎn)動(dòng)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(dòng)環(huán)方向看，順時(shí)針方向需要右旋彈簧，逆時(shí)針方向則要左旋彈簧.使用小彈簧時(shí)，要檢查各組彈簧的圈數(shù)和自由高度;6.對(duì)安裝機(jī)械密封的主機(jī)按技術(shù)要求檢查軸向串量、徑向跳動(dòng)、有關(guān)的垂直度、同心度、表面粗糙度、配合尺寸和對(duì)泵的聯(lián)軸節(jié)要求等.(1)軸向串量:要求不超過(guò)，一般在，軸向串量過(guò)大，使機(jī)械密封彈簧比壓不穩(wěn)定，引起密封端面過(guò)全磨損或泄漏，由于軸的抖動(dòng)而使密封破損。</p><p> 4其他機(jī)械密封性泄露除了以上幾種常見的泄露表現(xiàn)，還有機(jī)械密封振動(dòng)偏大、泵抽空引起的密封泄漏、密封腔中汽蝕引起的密封泄漏、密封端面汽化造成密封泄漏、泵振動(dòng)過(guò)大造成的密封泄漏、沒有沖洗的密封泄露故障等。機(jī)械密封性泄露的應(yīng)對(duì)措施1安裝防故障設(shè)備故障的出現(xiàn)與實(shí)際操作和機(jī)械內(nèi)部結(jié)構(gòu)有一定的關(guān)系，一些誘因會(huì)在一定情條件下引發(fā)故障的發(fā)生，只要找到相關(guān)誘因就能通過(guò)一些防故障設(shè)備消除故障誘因。比如在泵出口處安裝電接點(diǎn)壓力表，將泵機(jī)泵與泵出口處壓力建立連鎖，如果出現(xiàn)泵掉壓的情況就會(huì)自動(dòng)斷電。為防止自動(dòng)泵停泵時(shí)發(fā)生倒轉(zhuǎn)的現(xiàn)象，可以在自動(dòng)泵出口處加上單流閥。2改進(jìn)設(shè)備結(jié)構(gòu)機(jī)械密封在結(jié)構(gòu)設(shè)計(jì)上存在一定不合理性，這些不合理的結(jié)構(gòu)增加了機(jī)械密封的泄露風(fēng)險(xiǎn)。在條件允許的情況下可以對(duì)機(jī)械密封的結(jié)構(gòu)重新設(shè)計(jì)，將泄漏風(fēng)險(xiǎn)降到比較低。如機(jī)械密封的端面大都采用雙端面設(shè)計(jì)，雙端面增加了裝置與介質(zhì)的接觸面積，從而增加了腐蝕風(fēng)險(xiǎn)。從安全角度考慮可以將雙端面設(shè)計(jì)改成單端面封閉波紋管機(jī)械設(shè)計(jì)。3選取合適的組成材料不同材料的抗腐蝕性不同，介質(zhì)的腐蝕性要求機(jī)械密封組成材料具有良好的抗腐蝕性能，如果選擇材料不當(dāng)會(huì)降低設(shè)備的使用壽命。江蘇波紋管機(jī)械密封件。</p><div

三是安裝、拆卸困難，極易損壞靜環(huán)。誤區(qū)四：葉輪鎖母越緊越好？！機(jī)械密封泄漏中，軸套與軸之間的泄漏(軸間泄漏)是比較常見的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實(shí)導(dǎo)致軸間泄漏的因素較多，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過(guò)長(zhǎng)等都會(huì)導(dǎo)致軸間泄漏。鎖母鎖緊過(guò)度只會(huì)導(dǎo)致軸間墊過(guò)早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運(yùn)轉(zhuǎn)中鎖母會(huì)自動(dòng)適時(shí)鎖緊，使軸間始終處于良好的密封狀態(tài)。誤區(qū)五：新的比舊的好？！相對(duì)而言，使用新機(jī)械密封的效果好于舊的，但新機(jī)械密封的質(zhì)量或材質(zhì)選擇不當(dāng)時(shí)，配合尺寸誤差較大會(huì)影響密封效果；在聚合性和滲透性介質(zhì)中，靜環(huán)如無(wú)過(guò)度磨損，還是不更換為好。因?yàn)殪o環(huán)在靜環(huán)座中長(zhǎng)時(shí)間處于靜止?fàn)顟B(tài)，使聚合物和雜質(zhì)沉積為一體，起到了較好的密封作用。誤區(qū)六：拆修總比不拆好？！一旦出現(xiàn)機(jī)械密封泄漏便急于拆修，其實(shí)，有時(shí)密封并沒有損壞，只需調(diào)整工況或適當(dāng)調(diào)整密封就可消除泄漏。這樣既避免浪費(fèi)又可以驗(yàn)證自己的故障判斷能力，積累維修經(jīng)驗(yàn)提高檢修質(zhì)量。宣城橡膠波紋管機(jī)械密封件。濰坊常規(guī)機(jī)械密封</p><p

陶瓷由化學(xué)性質(zhì)不活潑的物質(zhì)組成，難以與介質(zhì)發(fā)生氧化反應(yīng)，因此在購(gòu)買機(jī)械密封時(shí)可以重點(diǎn)考慮使用陶瓷密封環(huán)。4提高操作員的專業(yè)技能機(jī)械密封的失效除了機(jī)械自身原因外還有人為因素的影響，例如操作員專業(yè)知識(shí)不足操作不當(dāng)導(dǎo)致不良后果的產(chǎn)生。為杜絕類似可避免失誤的產(chǎn)生，必須對(duì)操作員進(jìn)行專業(yè)知識(shí)培訓(xùn)，并制定作業(yè)指導(dǎo)書與注意事項(xiàng)說(shuō)明書，提倡標(biāo)準(zhǔn)作業(yè)，引進(jìn)防呆措施，定期對(duì)設(shè)備進(jìn)行維護(hù)。5提高檢修效果定期檢修是發(fā)現(xiàn)問(wèn)題和預(yù)防問(wèn)題的重要手段，然而許多員工卻將其當(dāng)做一般例行事項(xiàng)看待，認(rèn)為是走走過(guò)場(chǎng)，在檢修時(shí)只是做做樣子。員工的工作態(tài)度使一些問(wèn)題沒有在早期被發(fā)現(xiàn)，等到問(wèn)題徹底爆發(fā)為時(shí)已晚。員工在檢修時(shí)應(yīng)注重每一個(gè)細(xì)節(jié)，不忽視任何點(diǎn)滴，公司可以采取一些獎(jiǎng)勵(lì)措施，以此鼓勵(lì)員工檢修的積極性，從而提高檢修效果。機(jī)泵機(jī)械密封在生產(chǎn)中頻發(fā)泄漏故障，必須針對(duì)性解決故障，在分析故障發(fā)生原因的基礎(chǔ)上對(duì)設(shè)備進(jìn)行改進(jìn)，安裝防故障設(shè)備，做好定期維護(hù)管理，才能將故障發(fā)生概率降到比較低。濟(jì)寧國(guó)產(chǎn)機(jī)械密封</p><p
