在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動和停機時，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來代替)。 </p> <p> 大部分機械密封的設(shè)計采用較軟的材料來制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來，**通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。 </p> <p> 不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤滑的作用。然而，在填料盒內(nèi)，采用彈簧負載和液體壓力相結(jié)合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會影響接觸面之間形成液體薄膜，導致熱量增加和過早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。 </p> <p> 密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進行研磨。然后，采用單色光源的光柵板對其檢測。從這一觀點出發(fā)，對這些密封接觸面必須小心處理，并嚴格按照安裝說明，保證密封面得到適當?shù)谋Ｗo和正確就位，這一點是非常重要的。 </p> <p> <br /> </p>

離心泵用機械密封檢修中的幾個誤區(qū) </p> <p> 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(diào)節(jié)動環(huán)端面的能力，導致密封失效。2、動環(huán)密封圖越緊越好其實動環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，過于早漏;二是增大了動環(huán)軸向調(diào)整、移動的阻力，在工況變化頻繁時無法適時進行調(diào)整;三是彈簧過度疲憊易損壞;四是使動環(huán)密封圈變形，影響密封效果。 3、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(zhì)以石墨居多，一般較脆，過度受力極易引起碎裂;三是安裝、拆卸困難，極易損壞靜環(huán)。為了比較大發(fā)揮機械密封的實際性能，應對密封環(huán)的使用進行調(diào)查，掌握其工作壓力、溫度等情況，合理進行選擇。</p><div

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。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。鹽城多級泵密封銷售價格</p><p style="text-indent:25px">機械密封安裝調(diào)試好后，一般要進行靜試，觀察泄漏量。如泄漏量較小，多為動環(huán)或靜環(huán)密封圈存在問題。常州計量泵密封銷售廠家</p><p> 有害介質(zhì)時為了取得更好的密封效果，采用雙重密封，根據(jù)密封液系統(tǒng)壓力可分為有壓雙封(雙端面機械密封)和無壓雙封(串聯(lián)式機械密封)。 </p> <p> 有壓雙封密封液系統(tǒng)的壓力一般要比一級密封前的壓力高0.01-0.03MPa。這樣一級密封泄漏時，密封液會進入泵內(nèi)，確保了泵內(nèi)介質(zhì)不會泄漏到外界。由于密封液進入泵內(nèi)，密封液系統(tǒng)壓力、液位降低，可以實現(xiàn)密封的泄漏監(jiān)測和報警。 </p> <p> 無壓雙封密封系統(tǒng)內(nèi)的壓力一般為常壓或微壓，低于一級密封前的密封腔壓力。當一級密封泄漏時，泵內(nèi)介質(zhì)會進人密封液系統(tǒng)，導致密封液系統(tǒng)的壓力和液位升高，可以通過壓力開關(guān)或液位開關(guān)實現(xiàn)泄露監(jiān)測和報警。通過密封液系統(tǒng)來監(jiān)測雙端面機械密封失效與否，也是其區(qū)別于單端面機械密封**主要的形式之一。
