機(jī)械密封是靠一對(duì)或數(shù)對(duì)垂直于軸作相對(duì)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）作用下保持貼合并配以輔助密封而達(dá)到阻漏的軸封裝置。水泵常用機(jī)械密封結(jié)構(gòu)如圖所示。由靜止環(huán)（靜環(huán)）1、旋轉(zhuǎn)環(huán)（動(dòng)環(huán)）2、彈性元件3、彈簧座4、緊定螺釘5、旋轉(zhuǎn)環(huán)輔助密封圈6和靜止環(huán)輔助密封圈8等元件組成，防轉(zhuǎn)銷7固定在壓蓋9上以防止靜止環(huán)轉(zhuǎn)動(dòng)。旋轉(zhuǎn)環(huán)和靜止環(huán)往往還可根據(jù)它們是否具有軸向補(bǔ)償能力而稱為補(bǔ)償環(huán)或非補(bǔ)償還。機(jī)械密封中流體可能泄漏的途徑有如圖1中的A、B、C、D四個(gè)通道。C、D泄漏通道分別是靜止環(huán)與壓蓋、壓蓋與殼體之間的密封，二者均屬靜密封。B通道是旋轉(zhuǎn)環(huán)與軸之間的密封，當(dāng)端面摩擦磨損后，它**能追隨補(bǔ)償環(huán)沿軸向作微量的移動(dòng)，實(shí)際上仍然是一個(gè)相對(duì)靜密封。因此，這些泄漏通道相對(duì)來(lái)說比較容易封堵。靜密封元件常用的有橡膠O形圈或聚四氟乙烯V形圈，而作為補(bǔ)償環(huán)的旋轉(zhuǎn)環(huán)或靜止環(huán)輔助密封，有時(shí)采用兼?zhèn)鋸椥栽δ艿南鹉z、聚四氟乙烯或金屬波紋管的結(jié)構(gòu)。A通道則是旋轉(zhuǎn)環(huán)與靜止環(huán)的端面彼此貼合作相對(duì)滑動(dòng)的動(dòng)密封，它是機(jī)械密封裝置中的主密封，也是決定機(jī)械密封性能和壽命的關(guān)鍵。因此，對(duì)密封端面的加工要求很高。忻州襄樊五二五機(jī)械密封LC500/630II襄樊五二五機(jī)械密封LC550/700。</p><div

其余安裝及外型尺寸不受影響。副葉片和固定導(dǎo)葉加工難度較大，一般離心泵上沒有，在改造時(shí)可根據(jù)情況決定是否采用。在低于50m揚(yáng)程的泵也可不采用副葉片和固定導(dǎo)葉，只采用副葉輪。3、動(dòng)力密封裝置整體工作原理在運(yùn)轉(zhuǎn)時(shí)，離心泵工作葉輪與起密封作用的副葉輪同軸旋轉(zhuǎn)，工作葉輪泄漏出來(lái)的液體流到副葉輪后，通過副葉輪作用產(chǎn)生的壓力，與泄漏液體的壓力在副葉輪頂端與密封總成內(nèi)端面處達(dá)到平衡，從而使泄漏液體起到密封作用。在停車時(shí)，副葉輪動(dòng)力密封不起作用，泵內(nèi)液體壓力較小，泄漏到副葉輪的液體通過油封進(jìn)行密封。4、副葉輪動(dòng)力密封設(shè)計(jì)應(yīng)注意的問題（1）離心泵采用副葉輪密封無(wú)需考慮冷卻措施，若用于氣體密封，則需設(shè)置旁通回路從外部引入封液進(jìn)行冷卻。（2）副葉輪密封消耗的附加功率與其外徑的五次方成正比，因此一般不采用外徑過大的方案，而應(yīng)該同時(shí)設(shè)副葉片和副葉輪，以便減小外徑，減少功耗。（3）副葉輪動(dòng)力密封及停車密封裝置材料的選擇要根據(jù)使用介質(zhì)的要求來(lái)決定，否則要影響使用壽命，特別是停車密封還要考慮冷卻和潤(rùn)滑等。（4）因?yàn)楦比~輪葉片的進(jìn)口角同副葉輪的密封能力無(wú)關(guān)，所以葉片形狀可以用徑向直葉片以便加工制造。</p><p> 機(jī)械密封是旋轉(zhuǎn)軸用動(dòng)密封，分為接觸式和非接觸式兩種，目前多數(shù)采用接觸式機(jī)械密封，而非接觸式機(jī)械密封正在發(fā)展之中，并已引起人們注意.機(jī)械密封是機(jī)器上的非功能性零部件，但它在減少泄漏，穩(wěn)定生產(chǎn)上起了很大作用。機(jī)械密封的工作原理機(jī)械密封是用于旋轉(zhuǎn)鐘的動(dòng)密封，又稱端面密封，其主要特點(diǎn)是密封面垂直于(或大致)旋轉(zhuǎn)軸線，并且由彈性元件、輔助密封圈等構(gòu)成的軸向磨損補(bǔ)償機(jī)構(gòu)。機(jī)械密封的工作原理就是以兩個(gè)相互貼合，平的與旋轉(zhuǎn)軸線垂直的密封表面，并相對(duì)轉(zhuǎn)動(dòng)的密封裝置。它是靠彈性元件(如彈簧或波紋管)和密封介質(zhì)的壓力，隨軸旋轉(zhuǎn)的動(dòng)環(huán)和不隨軸旋轉(zhuǎn)的靜環(huán)的接觸端而上產(chǎn)生適當(dāng)?shù)膲壕o力，使這兩個(gè)接觸端面緊密貼合，端面間維持一層極薄的液膜，從而達(dá)到密封的目的。機(jī)械密封AIG318集裝式/以一臺(tái)單級(jí)臥室雙吸油泵為例/機(jī)械密封的作用一、提高機(jī)器效率、降低能耗。1、減少機(jī)器的內(nèi)漏、外漏和穿漏，提高機(jī)器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機(jī)械密封，使泵效率提高。2、減少摩擦損失，提高機(jī)器的機(jī)械效率。例如，將雙端面密封改為單端面密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失。MECP-65D3-S/SE7-62襄樊五二五機(jī)械密封。</p><div

將屏蔽泵改用機(jī)械密封泵，使電動(dòng)機(jī)效率提高;采用磁力傳動(dòng)泵，提高機(jī)器效率。4、改變輔助系統(tǒng)，減少能耗，提高機(jī)組效率。例如，熱油泵自沖洗改為小葉輪循環(huán)沖洗;雙端面密封改為單端面密封，節(jié)省封油輔助系統(tǒng)的能耗。二、節(jié)約原材料。例如，工藝流體回收，減少或消除動(dòng)力蒸汽和工藝流體的損耗，減少封油損耗等。三、提高機(jī)器可靠性。例如，軸封的漏損和壽命決定軸封和機(jī)器的可靠性。四、安全和環(huán)境保護(hù)。根據(jù)日本某廠調(diào)查報(bào)告，在發(fā)生的786件事故中有32件是泄漏造成的(占42%)。此外工藝流體泄漏還會(huì)造成環(huán)境污染，包括對(duì)大氣污染、水污染和車間環(huán)境污染。機(jī)械密封安裝、使用技術(shù)要領(lǐng)1.設(shè)備轉(zhuǎn)軸的徑向跳動(dòng)應(yīng)≤，軸向竄動(dòng)量不允許大于；2.設(shè)備的密封部位在安裝時(shí)應(yīng)保持清潔，密封零件應(yīng)進(jìn)行清洗，密封端面完好無(wú)損，防止雜質(zhì)和灰塵帶入密封部位；3.在安裝過程中嚴(yán)禁碰擊、敲打，以免使機(jī)械密封摩擦副破損而密封失效；4.安裝時(shí)在與密封相接觸的表面應(yīng)涂一層清潔的機(jī)械油，以便能順利安裝；5.安裝靜環(huán)壓蓋時(shí)，擰緊螺絲必須受力均勻，保證靜環(huán)端面與軸心線的垂直要求；6.安裝后用手推動(dòng)動(dòng)環(huán)，能使動(dòng)環(huán)在軸上靈活移動(dòng)，并有一定彈性；7.安裝后用手盤動(dòng)轉(zhuǎn)軸、轉(zhuǎn)軸應(yīng)無(wú)輕重感覺。LCP7S6-S/SV3-11/61襄樊五二五機(jī)械密封。忻州襄樊五二五機(jī)械密封LC500/630II</p><p

對(duì)石化行業(yè)來(lái)說，高溫重質(zhì)油泵用機(jī)械密封的選用一直是一大難題，例如催化裂化油漿泵、回?zé)捰捅?、常壓塔底泵、初餾塔底泵、減壓塔底泵、延遲焦化的輻射進(jìn)料泵等。高溫重質(zhì)油泵的介質(zhì)具有以下共同的特點(diǎn):溫度高:一般在340一400℃;介質(zhì)粘度大:在溫度下一般運(yùn)動(dòng)粘度為(12一180)X10一6m/s;介質(zhì)有顆粒:如催化劑、焦炭、含有砂粒等其他雜質(zhì)。對(duì)于高溫重油介質(zhì)泵用機(jī)械密封?，F(xiàn)在各個(gè)企業(yè)都采用焊接金屬波紋管械密封。現(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結(jié)構(gòu)，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。針對(duì)波紋管內(nèi)側(cè)結(jié)焦和結(jié)炭以及含固體顆粒等情況，解決的辦法有關(guān)資料己做了相關(guān)說明，比如采用蒸汽吹掃、摩擦副采用“硬對(duì)硬”、采用外沖洗等等，這些在一定程度上起到了較好的作用，這里不再過多闡述。但是以前提出的各種方法再實(shí)際應(yīng)用中由于種種因素的影響效果不夠理想。為了更好的提高機(jī)械密封的使用壽命，節(jié)資降耗，針對(duì)各種情況，建議應(yīng)把以下措施綜合起來(lái)采用:a)將金屬波紋升設(shè)計(jì)成旋轉(zhuǎn)型結(jié)構(gòu)。忻州襄樊五二五機(jī)械密封LC500/630II</p></p><br
