九、波紋管式機械密封波紋管式機械密封的應(yīng)用范圍很廣，從低溫到高溫，從中性介質(zhì)到腐蝕性介質(zhì)，從低速到高速，從普通到苛刻的工作條件都可選用。所有這些可通過變更波紋管的幾何形狀（如內(nèi)外徑、波片厚度和波數(shù)等）與材料彈性模量，改變波紋管的彈率。根據(jù)介質(zhì)的腐蝕性能，選用不同的波紋管材料等。例如對工作壓力和溫度都不高的中性介質(zhì)（油和水等），可選用橡膠制造的簡易波紋管密封；在腐蝕性介質(zhì)中（酸或減等），可選用四氟制造的波紋管密封；高溫和高速下，可采用焊接金屬波紋管機械密封等。焊接金屬波紋管密封的特點焊接金屬波紋管機械密封用的波紋管是由軋制的金屬薄板沖裁成環(huán)形波紋狀的型面，波形多采用S形，湖南脫硫泵用機械密封，將許多個波片重疊起來，分別在環(huán)形的外緣和內(nèi)緣進行焊接，組成一個波紋管，兩端再與傳動座和動環(huán)焊接成整體。除了不用輔助密封圈外，還具備使用溫度范圍***的特點，**高可達600度，湖南脫硫泵用機械密封，湖南脫硫泵用機械密封，**低可到一200度。此外高速下對軸的振動和振擺適應(yīng)性較強，有很好的補償能力，保證密封端面良好地貼合。但是長期在高溫下工作的焊接金屬波紋管密封，波紋管的彈率有減小的趨勢（俗稱“失彈”），使用受到一定的限制。嘉峪關(guān)飛力泵用機械密封選型。湖南脫硫泵用機械密封</p><div

對于非金屬材料的墊片，其壓力還會與工作溫度有關(guān)系，通常溫度乘以壓力的值（即PxT值）有一極限值，所以在選擇其工作壓力時，還要考慮墊片能承受的PxT值。下圖為GARLOCK常見壓制墊片的PxT值圖，不同型式的墊片所能夠承受的壓力也是不一樣的。圖7GARLOCK常見壓制墊片的P╳T值圖圖8為各種型式的墊片所適用的法蘭壓力等級尺寸在滿足法蘭粗糙度和不平度條件時，盡可能的選擇薄的墊片。墊片的厚度與其型式、材料、直徑、密封面的加工狀況和密封介質(zhì)等相關(guān)。對于大多數(shù)非金屬板材墊片而言，薄的墊片抵抗應(yīng)力松弛的能力也比較大。因薄的墊片其內(nèi)側(cè)跟介質(zhì)接觸的面積也小，所以沿墊片本體滲漏也隨之減少，并且此情況下墊片所承受的吹出力也小，墊片也就不容易被吹出，圖9形象的展示了薄墊片的抗吹出能力要比厚墊片強。當然也可以參考墊片標準選擇墊片厚度以及其它尺寸。圖9同樣工況下不同厚度墊片的徑向受力示意圖此外，由于墊片通常采用螺栓法蘭連接結(jié)構(gòu)，因此裝配時需要將螺栓預(yù)緊到足以達到密封的要求，另外，這一結(jié)構(gòu)中的墊片更是一個受很多因素影響的密封元件，因而如何控制預(yù)緊力是一個十分棘手的問題。各種墊片需要的壓緊載荷也各不相同，對于特殊要求的墊片密封。廣西泵用機械密封大全山西飛力泵用機械密封型號。</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。一般認為，軸間泄漏就是葉輪鎖母沒鎖緊，其實導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，軸頭螺紋過長等都會導致軸間泄漏。鎖母鎖緊過度只會導致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運轉(zhuǎn)中鎖母會自動適時鎖緊，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？！相對而言，使用新機械密封的效果好于舊的，但新機械密封的質(zhì)量或材質(zhì)選擇不當時，配合尺寸誤差較大會影響密封效果；在聚合性和滲透性介質(zhì)中，靜環(huán)如無過度磨損，還是不更換為好。因為靜環(huán)在靜環(huán)座中長時間處于靜止狀態(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)機械密封泄漏便急于拆修，其實，有時密封并沒有損壞，只需調(diào)整工況或適當調(diào)整密封就可消除泄漏。這樣既避免浪費又可以驗證自己的故障判斷能力，積累維修經(jīng)驗提高檢修質(zhì)量。</p><p> 五、與釜用機械密封有關(guān)的幾個參數(shù)1.使用壽命釜用機械密封的使用壽命一般規(guī)定半年以上.其實使用壽命與攪拌軸的轉(zhuǎn)速、密封尺寸、摩擦副材料等因素有關(guān).圖10-6為EKATO公司對不同尺寸的密封在不同轉(zhuǎn)速下的使用壽命試驗結(jié)果.2.適用范圍釜用密封的適用范圍與使用條件、何種輔助裝置有關(guān)，，每個密封公司都有其產(chǎn)品適用范圍的說明.圖10-7為EKATO公司RD023和RD200ST型密封在密封液貯罐和壓力平衡裝置兩種條件下的適用范圍圖.高溫機械密封機械密封的工作溫度超過80℃時就作為高溫機械密封(有的密封公司以工作溫度>90℃為界限)，在高溫下，密封主要間題有下列幾項:密封端面液體汽化，摩擦副的熱應(yīng)力和熱變雍，組合件、鑲嵌件可能因配合不當而松脫，輔助密封圈因高溫引起的老化、龜裂、粘結(jié)和彈性消失，彈簧疲勞和強度降低，材料的腐蝕和磨損加快.一、高溫機械密封的要求1.選用耐高溫的密封材料在高溫下，材料的耐溫性能顯得特別重要，合理選用密封材料可使一般結(jié)構(gòu)的機械密封仍能適用于高溫工作條件，簡化手續(xù)，節(jié)省開支.表10-1列出不同密封材料的使用極限溫度.2.采用金屬波紋管型機械密封或金屬波紋管與普通機械密封相結(jié)合的密封結(jié)構(gòu)從耐熱性能來看。北京渣漿泵用機械密封型號。</p><div

失效后也容易發(fā)現(xiàn)，本文不再贅述。螺紋密封螺紋密封在泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟密封，二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外。密封面的粗糙度以及與螺紋孔的相對幾何位置精度對密封效果影響也很大。于由密封墊片在擰緊螺紋時不僅承受壓緊力，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當墊片為非金屬時，一般只適用于壓力不高的場合，如果墊片為金屬則適用壓力可達30Mpa以上。泵上經(jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無論采用"錐對錐"還是"柱對錐"，密封效果相同，只是使用地域不同而已。我國目前兩種形式同等采用。影響密封效果的常見原因是在加工螺紋底孔時尺寸偏大，使螺紋牙形變短，牙頂變寬，造成密封面減小，當密封壓力升高后產(chǎn)生泄漏，甚至將絲堵壓出。天水循環(huán)泵用機械密封選型。廣西泵用機械密封大全</p><p

機械密封件泄漏所發(fā)生的部位是相當廣的，幾乎涉及所有的流體輸送與儲存的物體上。泄漏的形式及種類也是多種多樣的。首先介紹泄漏形式的分類方式：1.按泄漏的機理分類(1)界面泄漏：在密封件(墊片、填料)表面和與其接觸件的表面之間產(chǎn)生的一種泄漏。如法蘭與墊片之間、填料與軸或填料箱之間的泄漏。(2)滲透泄漏：介質(zhì)通過密封件(墊片、填料)本體毛細管滲透出來，這種泄漏發(fā)生在致密性較差的植物纖維、動物纖維和化學纖維等材料制成的密封件上。(3)破壞性泄漏：密封件由于急劇磨損、變形、變質(zhì)、失效等因素，使泄漏間隙增大而造成的一種危險陛泄漏。2.按泄漏量分類液體介質(zhì)泄漏分為五級(1)無泄漏：檢測不出泄漏為準。(2)滲漏：一種輕微泄漏。表面有明顯的介質(zhì)滲漏痕跡，像滲出的汗水一樣。擦掉痕跡，幾分鐘后又出現(xiàn)滲漏痕跡。(3)滴漏：介質(zhì)泄漏成水球狀，緩慢地流下或滴下，擦掉痕跡，5min內(nèi)再現(xiàn)水球狀滲漏者為滴漏。(4)重漏：介質(zhì)泄漏較重，連續(xù)成水珠狀流下或滴下，但未達到流淌程度。(5)流淌：介質(zhì)泄漏嚴重，介質(zhì)噴涌不斷，成線狀流淌。氣態(tài)介質(zhì)泄漏分為四級(1)無泄漏：用小紙條或纖維檢查為靜止狀態(tài)，用肥皂水檢查無氣泡者。(2)滲漏：用小紙條檢查微微飄動。湖南脫硫泵用機械密封</p><p
