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。由于填充物被密封介質(zhì)腐蝕而產(chǎn)生泄漏的現(xiàn)象在化工行業(yè)的用泵中也時有發(fā)生。薊州區(qū)格蘭富機械密封。</p><div

style="text-indent:25px">石家莊格蘭富機械密封。山東格蘭富機械密封大全</p><p> 泵的密封裝置主要分兩類：一類為靜密封，一類為動密封。靜密封通常有墊片密封、O型圈密封、螺紋密封等型式。動密封則主要有軟填料密封、油封密封、迷宮密封、螺旋密封、動力密封和機械密封等。造成泄漏的原因主要有兩個方面：一是密封面上有間隙。二是密封部位兩側(cè)存在壓力差，消除或減小任何一個因素都可以阻止或減小泄漏，達到密封的目的。泵的設計壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內(nèi)部的間隙。機械密封機械密封是現(xiàn)代泵軸封的主要方法，雖然利用它實現(xiàn)完全不泄漏不大容易，但是達到微小的，令人完全可以接受的泄漏量卻是完全可能的。但在泵的運行中卻經(jīng)常出現(xiàn)令人尷尬的局面，那么機械密封失效的原因是什么呢?1、械密封的材質(zhì)選擇不合適。機械密封的材質(zhì)與所輸送的介質(zhì)不相匹配。在工作時，密封元件很快被腐蝕，溶解或磨損，因而失去密封能力。所以根據(jù)輸送介質(zhì)的性質(zhì)而選擇機械密封的材質(zhì)是保證其密封功能和正常壽命的先決條件。2、機械密封的沖洗狀況不符合設計要求。在輸送易結(jié)晶或有細小顆粒的介質(zhì)時，必須有一定壓力和一定流量的沖洗液進行沖洗。山東格蘭富機械密封大全</p></p><br
