2）橡膠O形墊圈：斷面形狀是正圓，福州凱泉泵用機(jī)械密封KQH80-100，有一定的自緊作用，密封效果比平墊圈好，壓緊力更小。（3）塑料平墊圈：塑料的特點是耐腐蝕性好,大部分塑料耐溫性能不好。聚四氟乙烯為塑料之冠，不但耐腐蝕性能優(yōu)異，而且耐溫范圍比較寬闊，可在-180℃～+200℃之內(nèi)長期使用。（4）聚四氟乙烯包墊圈：為了充分發(fā)揮聚四氟乙烯的優(yōu)點，同時彌補(bǔ)它彈性較差的缺點，做成聚四氟乙烯包裹橡膠或石棉橡膠的墊圈。這樣，福州凱泉泵用機(jī)械密封KQH80-100，既同聚四氟乙烯平墊圈一樣耐腐蝕，又有良好的彈性，增強(qiáng)密封效果，減小壓緊力。其斷面形狀如圖4-20所示。（5）石棉橡膠墊圈：由石棉橡膠板剪成。它的組分是60～80%的石棉和10～20%的橡膠，以及填充劑、硫化劑等。它有很好的耐熱性、耐冷性、化學(xué)穩(wěn)定性，而且貨源豐富，價格便宜。使用時，壓緊力不必很大。由于它能粘附金屬，所以表面涂一層石墨粉，以免拆卸時費勁，福州凱泉泵用機(jī)械密封KQH80-100。石棉橡膠板有四種顏色：灰色，用于低壓(牌號XB-200，耐壓≤16公斤/平方厘米，耐溫200℃)；紅色，用于中壓(牌號XB-350，耐壓可達(dá)40公斤/平方厘米，耐溫350℃)；紫紅色，用于高壓(牌號XB-450，耐壓100公斤/平方厘米耐溫450℃)；綠色，用于油類，耐壓性能也很好。（6）金屬平熱圈：鉛，耐溫100℃；鋁430℃；銅315℃。MD100-50凱泉泵用機(jī)械密封。福州凱泉泵用機(jī)械密封KQH80-100</p><div

低碳鋼550℃；銀650℃；鎳810℃；蒙乃爾(鎳銅)合金810℃，不銹鋼870℃。其中鉛耐壓能力較差，鋁可耐64公斤/平方厘米，其他材料可耐高壓。（7）金屬異性墊圈：透鏡墊圈：有自緊作用，使用于高壓閥門。橢圓形墊圈：也屬于高壓自緊墊圈。錐面雙墊圈：用于高壓內(nèi)自緊密封。此外，還有方形、菱形、三角形、齒形、燕尾形、B形、C形等，一般只在高中壓閥門中使用。（8）金屬包皮墊圈：金屬既有良好的耐溫耐壓性能，又有良好的彈性。包皮材料有鋁、銅、低碳鋼、不銹鋼、蒙乃爾合金等。里面填充材料有石棉、聚四氟乙烯、玻璃纖維等。（9）波形墊圈：具有壓緊力小，密封效果好的特點。常采用金屬與非金屬組合的形式。（10）纏繞墊圈：是把很薄的金屬帶和非金屬帶緊貼在一起，纏繞成多層的圓形，斷面呈波浪狀，有很好的彈性和密封性。金屬帶可用08鋼、0Cr13、1Cr13、2Cr13、1Cr18Ni9Ti、銅、鋁、鈦、蒙乃爾合金等制作。非金屬帶材料有石棉、聚四氟乙烯等。以上，講述密封墊圈性能時，列舉了一些數(shù)字。必須說明，這些數(shù)字跟法蘭形式、介質(zhì)情況和安裝修理技術(shù)等有密切的關(guān)系，有時可以超過，有時達(dá)不到，而且耐壓和耐溫性能，也是互相轉(zhuǎn)化的，例如溫度高了，耐壓能力往往降低。福州凱泉泵用機(jī)械密封KQH80-100凱泉泵用機(jī)械密封KQWR-G150-315。</p><div

這種密封形式不同于靜密封和動密封，它具有截止、換向、節(jié)流、調(diào)節(jié)、減壓、安全、止回、分離等作用，它是一種特殊的密封裝置。這種泄漏很難治理。(4)本體泄漏：殼體、管壁、閥體、船體、壩身等材料自身產(chǎn)生的一種泄漏。如砂眼、裂縫等缺陷的泄漏。5.按泄漏的危害性分類(1)不允許泄漏：系指用感覺和一般方法檢查不出密封部位有泄漏現(xiàn)象的特殊工況。如極易燃易爆、劇毒、放射性介質(zhì)以及非常重要的部位，是不允許泄漏的。核電廠閥門要求使用幾十年仍舊完好不漏。(2)允許微漏：系指介質(zhì)允許微漏而不產(chǎn)生危害的工況。(3)允許泄漏：系指一定場合下的水和空氣類介質(zhì)的泄漏。6.按泄漏介質(zhì)的流向分類(1)向外泄漏：介質(zhì)從內(nèi)部往外部空間傳質(zhì)的一種現(xiàn)象。(2)向內(nèi)泄漏：外部空間的物質(zhì)向受壓體內(nèi)部傳質(zhì)的一種現(xiàn)象。如空氣和液體滲入真空設(shè)備容器中。(3)內(nèi)部泄漏：密封系統(tǒng)內(nèi)介質(zhì)產(chǎn)生傳質(zhì)的一種現(xiàn)象。如閥門在密封系統(tǒng)中關(guān)閉后的泄漏等。內(nèi)部泄漏難以發(fā)現(xiàn)和治理。7.按泄漏介質(zhì)種類分類如漏氣、漏汽、漏水、漏油、漏酸、漏堿、漏鹽等等。</p><p> 檢漏時亦可采用壓降法或靜態(tài)升壓法。為縮短試驗時間，各段檢漏可同時進(jìn)行。必要時應(yīng)采用其他檢測儀器和方法進(jìn)行檢漏，以確定每段的泄漏狀況，找出泄漏點。對于需進(jìn)行烘烤或冷卻的部件，必須經(jīng)冷、熱沖擊試驗后再進(jìn)行檢漏。例如冷阱、冷卻障板等部件，在烘烤除氣后，應(yīng)立即注入冷卻劑（液氮、氟里昂等），然后測量其泄漏率。值得注意的是，在這些過程中，泄漏不一定是在冷態(tài)或熱態(tài)出現(xiàn)。7、如果檢測出泄漏，又確定了泄漏點，就應(yīng)立即進(jìn)行修補(bǔ)或更換。修補(bǔ)或更換后的部件或設(shè)備應(yīng)重新進(jìn)行檢漏，直至合格為止。表7-4列出了部分泄漏原因和應(yīng)采取的措施。運行維修階段如果在以前各階段中，作了徹底檢漏并進(jìn)行了修補(bǔ)，通常短時間內(nèi)不會出現(xiàn)泄漏。正式運轉(zhuǎn)階段中，如果經(jīng)常出現(xiàn)泄漏，就應(yīng)根據(jù)產(chǎn)生泄漏的不同性質(zhì)，重新進(jìn)行計劃、設(shè)計和加工階段的審查。運行維修階段主要應(yīng)做好以下幾項工作。1、運轉(zhuǎn)日記為了能對事先制定的維修計劃不斷進(jìn)行修正，使之趨于完善，應(yīng)該詳細(xì)記錄設(shè)備每天的運轉(zhuǎn)狀況。設(shè)備的運轉(zhuǎn)日記里同時應(yīng)記錄泄漏方面的情況。不僅要記錄系統(tǒng)壓力、溫度、流量等的變化，而且應(yīng)把與泄漏有關(guān)的情況都記錄下來。由于泄漏與工況、介質(zhì)，設(shè)備的結(jié)構(gòu)、材料等諸多因素有關(guān)。凱泉泵用機(jī)械密封MD48-50。</p><div

迷宮密封效果很好。但在實際應(yīng)用中，因此而產(chǎn)生的化工泵泄漏卻很多，所以在化工泵密封中不常用，分析其原因主要有：1、密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車刀痕在有些情況下也加大了化工泵泄漏趨勢。2、化工泵軸承室內(nèi)潤滑油注入量太多，其溢出壓力超過了密封阻力。3、油窗或油位計安裝位置有誤，誤導(dǎo)了人們對油室內(nèi)潤滑油量的正確判斷.4、運轉(zhuǎn)中油溫的升高使其粘度降低，增加了化工泵泄漏的可能。5、回油槽或回油孔尺寸偏小，或受到其它障礙，使被阻滯的液體不能順利返回而造成泄漏。化工泵所抽取的介質(zhì)有腐蝕、揮發(fā)、等危險性的存在，對泵體的密封性能要求，要比其他種類的泵高很多。使用迷宮密封，就加大了化工泵輸送物料泄漏的危險度。所以，化工泵一般不采用此種密封方法?；け妹芊獾倪x擇化工泵經(jīng)常輸送的是具有腐蝕性，或是有毒揮發(fā)的介質(zhì)，因此其密封性能是衡量化工泵好與壞的標(biāo)準(zhǔn)之一。在選擇化工泵時，應(yīng)參考如下標(biāo)準(zhǔn)。1、密封形式有靜密封與動密封之分。對于靜密封，通常只采用密封圈和密封墊兩種密封形式，而在密封圈中又以O(shè)型圈的應(yīng)用性廣；對于動密封，很少采用填料密封。福州凱泉泵用機(jī)械密封KQH80-100</p></p><br
