由于機械密封具有密封性能好、工作可靠、泄漏量小、功率消耗少等特點，因而在國內(nèi)外煉油化工生產(chǎn)的旋轉(zhuǎn)設(shè)備中得到了較大規(guī)模的應(yīng)用，已經(jīng)成為泵、壓縮機、反應(yīng)釜、攪拌器等工藝設(shè)備能否正常運轉(zhuǎn)的關(guān)鍵部件。 </p> <p> 隨著環(huán)境保護和人類健康要求的提高，煉油裝置中對泵用機械密封的要求也在不斷提高。據(jù)統(tǒng)計，煉油裝置中機泵故障的40% 以上是由于機械密封發(fā)生泄漏而引起的。造成這一現(xiàn)象的原因，一是作為機泵中的動密封其本身所處的工作條件、起的作用所決定；二是許多國內(nèi)設(shè)計單位以及工程公司認為機械密封及系統(tǒng)的選用是泵廠和密封廠的責(zé)任，往往對密封的類型、布置方式、沖洗方案了解不深，難以制定機械密封的選配方案，造成部分密封選型不當。 </p> <p> <br />

src="https://tyunfile.71360.com/UploadFile/lscmjx/637247295062412109/3548299.jpg"></div><p> 平衡和非平衡式密封 </p> <p> 機械密封的平衡對接觸面的密封壓力有很大影響。這一密封壓力取決于密封本身的有效截面以及填料盒內(nèi)的壓力。 </p> <p> <span style="font-size:12px;"> 非平衡型密封的旋轉(zhuǎn)面相反一側(cè)的截面完全暴露于填料盒的壓力范圍之下，這種情況會使密封面之間產(chǎn)生很高的密封壓力，從而會使工作溫度提高，加快磨損速度。在高溫工作條件下或液體具有較大腐蝕性和磨擦性的情況下，會極大降低機械密封的使用壽命。</span> </p> <p> <span style="font-size:12px;"> 對機械密封加以平衡，可降低密封壓力，延長密封的使用壽命。一般采用帶有臺階的主軸和軸套，降低旋轉(zhuǎn)面的有效截面，就可達到上述目的。不過千萬別將凈密封壓力調(diào)節(jié)到接近零的水平，因為這樣做的結(jié)果可能會造成密封面之間的工作狀況不穩(wěn)定，并可能會因突然的變故而將密封吹開。</span> </p> <p> <span style="font-size:12px;"> 解決這些密封問題的答案也許是采用非平衡式密封，對于某些服務(wù)來說，也許采用非平衡式密封能達到更好的效果。例如，在某些應(yīng)用領(lǐng)域，與密封的使用壽命相比，也許更強調(diào)對液體泄漏造成的安全性問題。在這種情況下，對密封的選用也許可理解為更希望選擇具有較高的密封壓力。同樣，在選用較冷液體的密封時，操作溫度的增加也許是微不足道的。</span> </p> <p> <br /> </p><p> 螺紋密封 </p> <p> 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。 </p> <p> 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。熱裂是高溫油泵，如油渣泵、回?zé)捰捅谩⒊p壓塔底泵等最常見的失效現(xiàn)象。</p><div

水泵質(zhì)量跟機械密封的選擇安裝很關(guān)鍵。 </p> <p> 機械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機械基礎(chǔ)元件之一，是各種泵類設(shè)備的關(guān)鍵部件。對于機泵，超過50%機率的泄露問題產(chǎn)生原因往往就在機械密封上！ </p> <p> 機械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機械密封，耐高壓、耐腐蝕機械密封，耐顆粒介質(zhì)機械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機械密封。 </p> <p> 選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。 </p> <p> <p> 根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。 </p> <p> 根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。 </p> <p> 根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機械密封循環(huán)保護系統(tǒng)等。 </p> <p> 根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。 </p> 介質(zhì)的低于飽和蒸汽壓力，使得端面液膜發(fā)生閃蒸，喪失潤滑。鹽城油泵密封哪家比較好</p><p style="text-indent:25px">機械密封是依靠彈性元件對動、靜環(huán)斷面的預(yù)緊力來對軸向端面進行密封的，又稱為端面密封。南通清水密封供貨商</p><p> 為保證機械密封在高溫環(huán)境下正常工作，可以采取如下措施。 </p> <p> 給機封增加冷卻沖洗裝置。 </p> <p> 選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。 </p> <p> 選擇金屬波紋管機械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機封中，金屬波紋管取代了普通機封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。 </p> <p> <br /> 南通清水密封供貨商</p><p
