</p> <p> <br /> </p> 在密封面處由于干摩擦、冷卻水突然中斷，江蘇清水密封可定制企業(yè)，雜質(zhì)進入密封面、抽空等情況下，都會導(dǎo)致環(huán)面出現(xiàn)徑向裂紋。江蘇清水密封可定制企業(yè)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇清水密封可定制企業(yè),封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247293279589844/7625641.jpg"></div><p> 機械密封動、靜環(huán)之間的工作情況，大多數(shù)是處在邊界潤滑和半液體潤滑狀態(tài)下，而半液體潤滑能夠在摩擦系數(shù)較小即磨損與發(fā)熱令人滿意的情況下，獲得好的密封效果。 </p> <p> 機械密封的動、靜環(huán)之間的摩擦情況： </p> <p> 半液體潤滑： </p> <p> 滑動表面的凹坑處存有液體，接觸面之間維持一層很薄的液膜，所以發(fā)熱和磨損情況均較好，由于動、靜環(huán)之間的液膜在其出口處有表面張力，故限制了液體的泄露。 </p> <p> 完全液體潤滑： </p> <p> 但由于在這種情況下動、靜環(huán)之間的縫隙較大，故起不到密封作用，泄露嚴重。當動、靜環(huán)之間的壓力不足，而使間隙增大時，液膜增厚，這時不存在固體接觸，故無摩擦現(xiàn)象。在實際應(yīng)用中一般不允許有這種情況出現(xiàn)（受控膜機械密封除外）。 </p> <p> 干摩擦： </p> <p> 滑動摩擦面上無液體進入，因而無液膜存在，塵土和氧化層，以及吸附的氣體分子等。當動、靜環(huán)運轉(zhuǎn)時，其結(jié)果必然是使摩擦面發(fā)熱、磨損加劇而造成泄露。、邊界潤滑： </p> <p> 由于表面不是特別平的，而是凹凸不平，在凸出會有接觸磨損，而在凹處則保持液體的潤滑性能，造成邊界潤滑。當動、靜環(huán)之間的壓力增大或者液體在摩擦面上形成液膜的能力較差時，液體將從間隙中被擠出。邊界潤滑的磨損和發(fā)熱程度為中等。江蘇清水密封可定制企業(yè)密封常用名稱：密封圈、盤根、機械密封、油封、水封、盤根、密封墊板、密封膠、軟填料、液壓、氣動密封件。</p><div

泵用機械密封的安裝和使用機械密封大多用于各種類型的泵。機械密封是一種精度較高的密封裝置，對安裝和使用條件均有一定的要求。機械密封安裝使用的一般原則弄清設(shè)備的情況，要了解設(shè)備轉(zhuǎn)軸的轉(zhuǎn)速、軸徑；設(shè)備制造精度及密封腔尺寸，設(shè)備本身的使用壽命以及設(shè)備在生產(chǎn)工藝中的地位等要做均衡的考慮。估算介質(zhì)壓力。泵的密封腔壓力一般不是泵的出口壓力，而是低于泵的出口壓力。弄清密封介質(zhì)情況。要知道密封介質(zhì)的狀態(tài)，是氣態(tài)還是液態(tài)，介質(zhì)是否含顆粒及顆粒狀況；了解介質(zhì)的性質(zhì)、溫度，以便合理選型及采取必要的冷卻、沖洗、潤滑措施。機械密封安裝使用的技術(shù)要求安裝機械密封部位的軸或軸套的徑向跳動公差：Ф10~50mmФ50~120mm,。軸或軸套的表面粗糙度應(yīng)符合技術(shù)要求，外徑尺寸公差為h6。傳動軸的軸向竄動量不超過。密封腔體端面對軸表面的跳動公差：軸或軸套外徑端面跳動公差:Ф10~50mm，Ф50~120mm,軸或軸套的端面及密封腔體的端面要有倒角。軸徑≤Φ30mm時為3×10°，軸徑＞Φ30mm時為4×10°。當輸送介質(zhì)溫度偏高、過低或含有雜質(zhì)顆粒、易燃、易爆、時，應(yīng)采取相應(yīng)的阻封、沖洗、冷卻、過濾等措施。 </p><p> </p> <p> 一般情況下，介質(zhì)的溫度超過120℃即認為是高溫密封。此時機械密封存在的主要問題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長時間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會加劇金屬材料的腐蝕，縮短機封的使用壽命。各種密封其性能影響因素是不同的，如機械密封(填料密封等)影響因素有溫度、介質(zhì)、磨損、所承受壓力等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇清水密封可定制企業(yè),封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247295161962890/6395142.jpg"></div><p> 高溫熱油泵主要有常底泵、減底泵、催化油漿泵，該類泵的特點是溫度高（370℃-400℃）、油品粘度大、塔底有雜質(zhì)。我們針對高溫泵的這些特點采用的是YH-609系列機械密封, 結(jié)構(gòu)選型主要結(jié)合了以下幾個方面: </p> <p> 金屬波紋管旋轉(zhuǎn)結(jié)構(gòu) </p> <p> 旋轉(zhuǎn)波紋管密封在旋轉(zhuǎn)離心力作用下可以自身清洗波紋管，減少波紋管**沉積和內(nèi)側(cè)結(jié)焦，并能防止因急冷造成的波紋管變形。泵類設(shè)備轉(zhuǎn)速一般為2950r/min，機械密封線速度遠小于25m/s,因此，可以選用旋轉(zhuǎn)結(jié)構(gòu)。 </p> <p> 密封結(jié)構(gòu)形式采用開槽斜面擠緊軸套 </p> <p> 這種定位傳動可靠，安裝拆卸方便且不傷軸。并設(shè)置有限位板，便于泵外調(diào)整密封的壓縮量。波紋管內(nèi)徑一處設(shè)一45℃斜角，以分散應(yīng)力，延長波紋管壽命。輔助密封采用柔性石墨替代合成橡膠，可以承受高達425℃的高溫。 </p> <p> 摩擦副材料的選取 </p> <p> 對摩擦副材料的選取我們采用“硬對硬”結(jié)構(gòu)，起初動靜環(huán)我們選擇了SiC-WC，但是運轉(zhuǎn)一段時間發(fā)現(xiàn)動環(huán)出現(xiàn)肯邊現(xiàn)象。改用YG6-YG6之后，設(shè)備運轉(zhuǎn)一直正常。 </p> <p> <br /> 由于介質(zhì)和工作條件的不同，機械密封對耐高溫性能、耐高壓性能、耐腐蝕性能往往有著比較大的差距。江蘇清水密封可定制企業(yè)</p><p style="text-indent:25px">在實際安裝過程中，應(yīng)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。江蘇清水密封可定制企業(yè)</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 /> 江蘇清水密封可定制企業(yè)</p><p>
