非平衡型密封的旋轉面相反一側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，會降低機械密封的使用壽命。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節(jié)到接近零的水平，因為這樣做的結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。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，在某些應用領域，與密封的使用壽命相比，也許更強調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。不管出于何種考慮，當填料盒的壓力超過50psi時，一般推薦使用平衡式密封。內(nèi)密封和外密封通常的做法是將密封安裝在填料盒的內(nèi)部。但這種做法要求在密封維修時將液泵的濕端拆卸下來。機械密封CRNE

機泵機械密封是動力機械和流體機械裝置中不可缺少的零件，對機械的安全性要有重要意義。機泵機械密封泄漏的原因多種多樣，比如密封沖洗水的問題、裝置本身存在的缺陷、填充介質對裝置的腐蝕性、密封性能不足等，針對這些問題必須從根源入手，依次解決工藝、設備、檢修、操作上的問題，只有做到排除故障才能徹底解決機械的密封問題，保證機泵機械的良好運轉。實際生產(chǎn)中，不同的操作條件和生產(chǎn)條件會對機泵機械密封產(chǎn)生重要的影響，甚至可能導致機泵機械失去基本性能，因此對機泵機械密封泄漏原因的分析具有重要的實際生產(chǎn)意義和安全意義，原因分析能提高安全性、機械的稼動率。機械的壽命等，因此機械密封的選擇為維護歷來是眾多企業(yè)的重中之重。機泵機械密封失效的原因腐蝕引起機械密封的失效機泵機械密封的腐蝕包括金屬環(huán)腐蝕、非金屬環(huán)腐蝕以及輔助密封圈及接觸部位的腐蝕。1金屬環(huán)腐蝕金屬環(huán)本身不具備抗腐蝕能力，直接接觸到腐蝕性介質表面會被腐蝕，初期階段會出現(xiàn)怪聲、泄露、磨損等現(xiàn)象。腐蝕會以一定的速度往內(nèi)部蔓延。在外力的作用下金屬環(huán)會發(fā)生應力變形，變形后外露的部分是腐蝕的重災區(qū)，并通過薄弱環(huán)節(jié)逐漸影響到其他區(qū)域，進而產(chǎn)生機械密封泄漏。</p><p> 如油渣泵、回煉油泵、常減壓塔底泵等常見的失效現(xiàn)象。在密封面處由于干摩擦、冷卻水突然中斷，雜質進入密封面、抽空等情況下，都會導致環(huán)面出現(xiàn)徑向裂紋；b）石墨炭化是使用碳-石墨環(huán)時密封失效的主要原因之一。由于在使用中，如果石墨環(huán)一旦超過許用溫度（一般在-105～250℃）時，其表面會析出樹脂，摩擦面附近樹脂會發(fā)生炭化，當有粘結劑時，會發(fā)泡軟化，使密封面泄漏增加，密封失效；c）輔助密封件（如氟橡膠、乙丙橡膠、全橡膠）在超過許用溫度后，將會迅速老化、龜裂、變硬失彈?，F(xiàn)在所使用的柔性石墨耐高溫、耐腐蝕性較好，但其回彈性差。而且易脆裂，安裝時容易損壞。6、由于密封端面的磨損而造成的密封失效a）摩擦副所用的材料耐磨性差、摩擦系數(shù)大、端面比壓（包括彈簧比壓）過大等,都會縮短機械密封的使用壽命。對常用的材料，按耐磨性排列的次序為：碳化硅-碳石墨、硬質合金-碳石墨、陶瓷-碳石墨、噴涂陶瓷--碳石墨、氮化硅陶瓷--碳石墨、高速鋼--碳石墨、堆焊硬質合金--碳石墨。b）對于含有固體顆粒介質，密封面進入固體顆粒是導致使密封失效的主要原因。固體顆粒進入摩擦副端面起研磨劑作用，使密封發(fā)生劇烈磨損而失效。密封面合理的間隙。蕪湖橡膠波紋管機械密封廠。</p><div

機械密封是一種旋轉機械的軸封裝置，機械密封又叫端面密封，在國家有關標準中是這樣定義的:"由至少一對垂直于旋轉軸線的端面在流體壓力和補償機構彈力(或磁力)的作用以及輔助密封的配合下保持貼合并相對滑動而構成的防止流體泄漏的裝置"。常用機械密封結構由靜止環(huán)(靜環(huán))、旋轉環(huán)(動環(huán))、彈性元件彈簧座、緊定螺釘、旋轉環(huán)輔助密封圈和靜止環(huán)輔助密封圈等元件組成，防轉銷固定在壓蓋上以防止靜止環(huán)轉動。機械密封在日常檢修中，常常會存在以下幾個誤區(qū)：誤區(qū)一：彈簧壓縮量越大密封效果越好？！其實不然，彈簧壓縮量過大，可導致摩擦副急劇磨損，瞬間燒損；過度的壓縮使彈簧失去調節(jié)動環(huán)端面的能力，導致密封失效。誤區(qū)二：動環(huán)密封圈越緊越好？！其實動環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，過***漏；二是增大了動環(huán)軸向調整、移動的阻力，在工況變化頻繁時無法適時進行調整；三是彈簧過度疲勞易損壞；四是使動環(huán)密封圈變形，影響密封效果。誤區(qū)三：靜環(huán)密封圈越緊越好？！靜環(huán)密封圈基本處于靜止狀態(tài)，相對較緊密封效果會好些，但過緊也是有害的。一是引起靜環(huán)密封因過度變形，影響密封效果；二是靜環(huán)材質以石墨居多，一般較脆，過度受力極易引起碎裂。無錫109-25機械密封件。機械密封CRNE

2）對安裝機械密封時壓縮量過大，導致摩擦副端面嚴重磨損、擦傷；（3）動環(huán)密封圈過緊，彈簧無法調整動環(huán)的軸向浮動量；（4）靜環(huán)密封圈過松，當動環(huán)軸向浮動時，靜環(huán)脫離靜環(huán)座；（5）工作介質中有顆粒狀物質，運轉中進人摩擦副，探傷動、靜環(huán)密封端面；（6）設計選型有誤，密封端面比壓偏低或密封材質冷縮性較大等。上述現(xiàn)象在試運轉中經(jīng)常出現(xiàn)，有時可以通過適當調整靜環(huán)座等予以消除，但多數(shù)需要重新拆裝，更換密封。3.由于兩密封端面失去潤滑膜而造成的失效a）因端面密封載荷的存在，在密封腔缺乏液體時啟動泵而發(fā)生干摩擦；b）介質的低于飽和蒸汽壓力，使得端面液膜發(fā)生閃蒸，喪失潤滑；c）如介質為易揮發(fā)性產(chǎn)品，在機械密封冷卻系統(tǒng)出現(xiàn)結垢或阻塞時，由于端面摩擦及旋轉元件攪拌液體產(chǎn)生熱量而使介質的飽和蒸汽壓上升，也造成介質壓力低于其飽和蒸汽壓的狀況。4.由于腐蝕而引起的機械密封失效a）密封面點蝕，甚至穿透。b）由于碳化鎢環(huán)與不銹鋼座等焊接，使用中不銹鋼座易產(chǎn)生晶間腐蝕；c）焊接金屬波紋管、彈簧等在應力與介質腐蝕的共同作用下易發(fā)生破裂。5.由于高溫效應而產(chǎn)生的機械密封失效a）熱裂是高溫油泵。機械密封CRNE
