臥式高溫離心泵機(jī)械密封泄漏的分析與改造臥式高溫離心泵在化工生產(chǎn)中起到很重要的作用,然而在運(yùn)行的過程中卻經(jīng)常會出現(xiàn)問題,主要問題就是其驅(qū)動(dòng)端與非驅(qū)動(dòng)端機(jī)械密封經(jīng)常泄漏,并且泄漏量很大嚴(yán)重時(shí),24h的泄漏量能裝一桶潤滑油,這種泄漏狀態(tài)給裝置的平穩(wěn)運(yùn)行和環(huán)境保護(hù)造成了很大的壓力,在分析了泄漏原因以后提出了相應(yīng)的改造方案。臥式高溫離心泵案例：某一高溫高壓多級離心泵是某廠主要設(shè)備,故障后全廠化工系統(tǒng)都無法正常運(yùn)轉(zhuǎn),而且維修周期較長,會給廠區(qū)的的安全穩(wěn)定生產(chǎn)帶來極大的隱患。2014年因液位指示有誤,甲醇洗中壓閃蒸塔上段液位指示瞬間歸零,進(jìn)而造成泵入口斷液，濱海新區(qū)CR/I/N1S1/3/5HQQV格蘭富機(jī)械密封,泵出口流量由降為零。該多級離心泵在缺液運(yùn)行過程中,發(fā)生了強(qiáng)烈的氣蝕、振動(dòng)和發(fā)熱,造成該泵損壞非常嚴(yán)重,轉(zhuǎn)子與口環(huán)抱死、主軸彎曲變形、泵殼變形、機(jī)械密封損壞。后經(jīng)拆解發(fā)現(xiàn)一、二、三、四級泵體口環(huán)與葉輪口環(huán)磨損嚴(yán)重中間節(jié)流套及襯套磨損嚴(yán)重,局部有咬合現(xiàn)象,表面因受高溫而發(fā)藍(lán)變色凹，濱海新區(qū)CR/I/N1S1/3/5HQQV格蘭富機(jī)械密封。臥式高溫離心泵機(jī)封泄漏原因：1.機(jī)泵長周期的運(yùn)行運(yùn)行時(shí)間長是造成臥式高溫離心泵機(jī)封泄漏的要原因之一，濱海新區(qū)CR/I/N1S1/3/5HQQV格蘭富機(jī)械密封,具體現(xiàn)象為:高溫高壓多級泵機(jī)械密封在長時(shí)間的運(yùn)行之后,整個(gè)轉(zhuǎn)子的軸向竄量會越來越大。臨漳格蘭富機(jī)械密封件。濱海新區(qū)CR/I/N1S1/3/5HQQV格蘭富機(jī)械密封</p><div

3、喉部襯套間隙必須保證足夠小，以保證腔壓。間隙只要保證金屬件不摩擦接觸即可，一般取直徑間隙；4、易凝固、聚合、臟污介質(zhì)不能采用此方案；5、泵在運(yùn)轉(zhuǎn)腔需將系統(tǒng)充分排氣。PLAN02+52方案特點(diǎn)：1、儲液罐配置液位及壓力報(bào)警開關(guān)，可實(shí)時(shí)監(jiān)控機(jī)封泄漏情況，進(jìn)行及時(shí)維護(hù)。2、機(jī)封為雙端面波紋管密封，在一級密封失效時(shí)二級密封實(shí)現(xiàn)主密封功能，提高安全等級3、與單端面密封相比，雙重非承壓密封能降低回路泄漏風(fēng)險(xiǎn)。4、緩沖液壓力低于介質(zhì)壓力，此方案只適用于輕質(zhì)餾分油類。API02方案的功能：1、采用夾套對密封腔冷卻，冷卻介質(zhì)不進(jìn)入流程。2、可用于起泵前的暖泵。API02方案的構(gòu)成：泵體上需設(shè)計(jì)夾**場條件：1、現(xiàn)場需要具備單獨(dú)的冷卻水線/低壓蒸汽連接到換熱器上，不能與其它設(shè)備并聯(lián)使用一條水線，冷卻水需要采用軟化水，以防止結(jié)垢。3、喉部襯套間隙必須保證足夠小，以防止過多的熱流體進(jìn)入密封腔。PLAN32+53A方案特點(diǎn)：1、封液壓力高于介質(zhì)壓力，保證高溫工藝介質(zhì)零逸出；2、儲液罐配置液位及壓力報(bào)警開關(guān)，可實(shí)時(shí)監(jiān)控機(jī)封運(yùn)轉(zhuǎn)情況，提高了安全等級；3、機(jī)封為串聯(lián)波紋管密封，在一級密封失效時(shí)二級密封實(shí)現(xiàn)主密封功能，提高設(shè)備運(yùn)行安全等級。濱海新區(qū)CR/I/N1S1/3/5HQQV格蘭富機(jī)械密封江蘇格蘭富機(jī)械密封大全。</p><div

填料密封是靠盤根的壓緊在軸上或軸套上起作用的。填料密封與軸直接摩擦，填料壓的越緊摩擦力就越大、消耗功率也就越大。而機(jī)械密封的摩擦是處于半液摩擦狀態(tài)，摩擦系數(shù)非常的小，機(jī)械密封的功率損失是填料密封的10～50%。（6）波紋管密封軸或軸套不受磨損，對旋轉(zhuǎn)軸的振擺和軸對殼體的偏斜不敏感。（7）適用范圍廣。當(dāng)介質(zhì)易燃、易爆、有毒有害時(shí)，采用機(jī)械密封可保證密封。它還適用于高溫、低溫、高壓、真空各種轉(zhuǎn)速的及腐蝕介質(zhì)的設(shè)備密封。2、缺點(diǎn)（1）如結(jié)構(gòu)比填料密封復(fù)雜，加工精度要求高，并要求一定的安裝技術(shù)等，特別是干氣密封的安裝要求更高。而且密封技術(shù)發(fā)展的很快，新技術(shù)不斷出現(xiàn)給我們維修帶來了新的課題。（2）結(jié)構(gòu)復(fù)雜、拆裝不便。與其它密封比較，機(jī)械端面密封的零件數(shù)目多，要求精密，結(jié)構(gòu)復(fù)雜。特別是在裝配方面較困難，拆裝時(shí)要從軸端抽出密封環(huán)，必須把機(jī)器部分（聯(lián)軸器）或全部拆卸。這一問題目前已作了某些改進(jìn)，例如采用拆裝方便并可保證裝配質(zhì)量的剖分式和集裝式機(jī)械密封等。三、機(jī)械密封的工作原理機(jī)械密封亦稱端面密封，是靠一對或數(shù)對垂直于軸作相對滑動(dòng)的端面在流體壓力和補(bǔ)償機(jī)構(gòu)的彈力（或磁力）作用下。</p><p> 新的密封形式和密封材料陸續(xù)出現(xiàn)，其必然對泵的密封技術(shù)產(chǎn)生直接的影響和推動(dòng)。長壽命、零泄漏的泵類產(chǎn)品會在越來越多的場合得到推廣和應(yīng)用。油封密封油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場合。油封應(yīng)安裝在制造精度為h8～h9，表面粗糙度為～μm且經(jīng)過表面硬化處理的軸上。密封介質(zhì)不應(yīng)含有固體微粒和雜質(zhì)，否則會造成油封和軸的迅速磨損而使密封失效。墊片密封墊片是離心泵靜密封的基本元件，使用范圍非常廣。墊片的選型主要根據(jù)泵輸送介質(zhì)、溫度、壓力和腐蝕性等因素決定。當(dāng)溫度和壓力不高時(shí)一般選用非金屬密封墊片;中壓高溫時(shí)，選用非金屬與金屬組合墊片。非金屬墊片在泵上應(yīng)用普遍，其材料一般為紙、橡膠和聚四氟乙烯。當(dāng)溫度不超過120℃，壓力在，一般選用青殼紙或模造紙墊片。如果輸送介質(zhì)為油，溫度在-30～110℃時(shí)(公眾號:泵管家)，一般選用耐老化性能較好的丁晴橡膠。當(dāng)輸送介質(zhì)在-50～200℃時(shí)，選用氟橡膠更為合適。因?yàn)樗四陀湍蜔嵬?，機(jī)械強(qiáng)度大也是其主要特征。在化工泵中。格蘭富機(jī)械密封CR15-4。</p><div

軸與輔助密封的過盈量越來越大,動(dòng)環(huán)與軸的摩擦力也會越來越大,在高溫高壓多級泵的運(yùn)行過程中動(dòng)靜環(huán)磨損卻得不到位移補(bǔ)償,解決這種現(xiàn)象的辦法是:定期將高溫高壓多級泵切換運(yùn)行對機(jī)封進(jìn)行檢查和維護(hù),回裝時(shí)一定注意軸向竄量要小于。高溫高壓多級離心泵在運(yùn)行的過程中,很有可能會出現(xiàn)泵軸的周期性振動(dòng)。這種現(xiàn)象會極大的影響高溫高壓多級泵機(jī)械密封的使用壽命,解決的辦法是:參照國家標(biāo)準(zhǔn)進(jìn)行檢維修,避免這種現(xiàn)象造成的機(jī)械密封失效。介質(zhì)不干凈,如果介質(zhì)中顆粒較大,會造成摩擦副的泄漏,要及時(shí)清理泵入口的過濾器。介質(zhì)腐蝕性較大,如果密封圈被介質(zhì)腐蝕造成泄漏,就要考慮提高材質(zhì)的等級了2.運(yùn)行環(huán)境惡劣對于一些運(yùn)行環(huán)境惡劣的離心泵來說,機(jī)械密封難以滿足工作介質(zhì)要求在運(yùn)行了一段時(shí)間以后就會發(fā)生機(jī)械密封泄漏的情況。彈性元件損壞引起泄漏。對于一些工作介質(zhì)易結(jié)晶或者含雜質(zhì)較多的離心泵來說,在將其解體檢修時(shí),會發(fā)現(xiàn)其所用機(jī)械密封的彈性元件被結(jié)晶物或雜質(zhì)垢結(jié)堵塞,從而使彈性元件失去彈性,失彈的彈性元件無法給予動(dòng)環(huán)應(yīng)有的軸向補(bǔ)償,從而導(dǎo)致機(jī)械密封出現(xiàn)泄漏的情況第二,輔助密封圈損壞引起泄漏。若工作介質(zhì)溫度過高,或者工作介質(zhì)中含有弱酸、弱堿等腐蝕性物質(zhì)。南宮格蘭富機(jī)械密封件。濱海新區(qū)CR/I/N1S1/3/5HQQV格蘭富機(jī)械密封</p><p
