機械密封彈簧壓縮量調(diào)試時有哪些要求？答：機械密封彈簧唄傳動螺釘壓縮一個量，叫彈簧的壓縮量。機械密封全部安裝完畢，相對于彈簧又壓縮一個量，這個量稱機械密封壓縮量。機械密封彈簧總的壓縮量是傳動螺釘壓縮量和彈簧自身彈力之和。在裝配時，機械密封壓縮量越大，彈簧對動環(huán)的作用力越小。因此，機械密封工作原理，彈簧的大小對機械密封的性能和壽命影響很大，所以裝配一定要按技術要求來調(diào)整壓縮量。 </p> <p> <p> 靜環(huán)組件安裝時有哪些注意事項？答：1）將經(jīng)過檢查的靜環(huán)密封圈從靜環(huán)尾部套入，把靜環(huán)組件裝入壓蓋或密封腔。在任何情況下，都不得給機械密封零件或部件施加沖擊力。被壓面應墊上干凈的紙板或布，以免損傷密封端面。2）組裝成旋轉型動環(huán)組件或靜止型的靜環(huán)組件后，用手按動補償環(huán)，檢查是否裝到位，是否靈活；彈性開口是否定位可靠。3）密封端面與軸或軸套中心線的垂直度是否符合要求。4）對靜止型機械密封，靜環(huán)組件的防轉銷引線要準確，推進靜環(huán)組時，組件的銷槽要對準銷子，推進到位后，要測量組件端面至密封腔某端面的距離，判斷是否安裝到位；5）擰螺栓壓緊端蓋時，南通容積泵密封生產(chǎn)企業(yè)，要用力均勻、對稱，分幾次擰完，南通容積泵密封生產(chǎn)企業(yè)，不可一次緊定，南通容積泵密封生產(chǎn)企業(yè)，以免偏斜，甚至壓碎石墨環(huán)。

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。常州離心泵密封批量采購在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)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。</p><div

安裝時，若軸徑外表面粗糙度低或有銹斑、銹蝕、起毛刺等缺點，要用細砂布或油石打磨光滑；在油封唇口或軸徑對應位置涂上清潔機油或潤滑油脂。 </p> <p> 油封外圈涂上密封膠，用硬紙把軸上的鍵槽部位包起來，避免劃傷油封唇口，用**工具將油封向里旋轉壓進，千萬不能硬砸硬沖，以防油封變形或擠斷彈簧而失效；若出現(xiàn)唇口翻邊、彈簧脫落和油封歪斜時必須拆下重新裝入。應該注意的是：當軸徑?jīng)]有磨損和油封彈簧彈力足夠時，不要擅自收緊內(nèi)彈簧。應用在機械上的油封一般工作條件惡劣、環(huán)境溫差大、塵埃多、機具振動頻繁使機件受力狀況不斷變化時，要勤檢查、保養(yǎng)和維護。 </p> <p> 如軸徑和軸承磨損嚴重；油封橡膠老化或彈簧失效等，應及時進行修理和更換相應部件。 </p> <p> 對不正常發(fā)熱的部件或總成應及時排除故障；避免機械超速、超負荷運轉，以防止油封唇口溫度升高、橡膠老化、唇口早期磨損等。 </p> <p> <br /> </p> <p> <br /> </p><p> 在設計合理，加工精良，裝配完好、轉速較高時，迷宮密封效果很好。但在實際應用中，因此而產(chǎn)生的泄漏卻很多，分析其原因主要有： </p> <p> 密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車刀痕在有些情況下也加大了泄漏趨勢。 </p> <p> 軸承室內(nèi)潤滑油注入量太多，其溢出壓力超過了密封阻力。 </p> <p> 油窗或油位計安裝位置有誤，誤導了人們對油室內(nèi)潤滑油量的正確判斷。 </p> <p> 運轉中油溫的升高使其粘度降低，增加了泄漏的可能。 </p> <p> 回油槽或回油孔尺寸偏小，或受到其它障礙，使被阻滯的液體不能順利返回而造成泄漏。在實際安裝過程中，應該做好對裝配圖的核對工作，并檢各種零件表面是否出現(xiàn)了劃痕、缺點等情況。</p><div

style="font-size:12px;">金屬骨架就如同混凝土構件里面的鋼筋，起到加強的作用，并使油封能保持形狀及張力。通常，在自由狀態(tài)下的骨架油封，其內(nèi)徑比軸徑小，即具有一定的“過盈量”。因此，當油封裝入油封座和軸上之后，油封刃口的壓力和自緊螺旋彈簧的收縮力對軸產(chǎn)生一定的徑向緊力，經(jīng)過一段時間運行后，該壓力會迅速減小乃至消失，因而，加上彈簧可以隨時補償油封自緊力。</span>

在液體介質(zhì)中工作的機械密封，一般均依靠液體介質(zhì)在動、靜環(huán)摩擦面間所形成的液膜進行潤滑。因此，維持摩擦面間的液膜是機械密封穩(wěn)定運轉、延長使用壽命所必不可少的。 </p> <p> 強化潤滑的結構 </p> <p> 靜壓潤滑： </p> <p> 所謂靜壓潤滑是將有壓力的潤滑液體直接引入摩擦面以起到潤滑的作用。用此有壓力的潤滑液與機械內(nèi)的流體壓力相對抗，此種形式通常也稱為流體靜壓力密封。引入的潤滑液體由單獨的液源供給，如液壓泵等。只要條件允許，應盡可能把氣體介質(zhì)條件轉換為液體介質(zhì)條件，這樣既便于潤滑又便于密封。氣體介質(zhì)的機械密封應采取措施建立氣膜潤滑，如采用氣體靜壓受控膜機械密封或固體潤滑，即選用自潤滑材料作動環(huán)或靜環(huán)。 </p> <p> 端面偏心： </p> <p> 一般機械密封，動環(huán)的中心、靜環(huán)的中心和軸的中心線都在一條直線上，偏心尺寸不能過大，特別是對于高壓，偏心會使端面所受的壓力不均勻，而造成磨損不均勻。對于高轉速密封，不宜用動環(huán)作為偏心環(huán)，否則由于離心力的平衡會使機器發(fā)生振動。如果將動環(huán)或靜環(huán)中的某一個環(huán)的端面中心做成與軸的中心線偏移部分距離，便能使環(huán)在旋轉時不斷帶入潤滑液至滑動面間起潤滑作用。
