class="page-proshow02"><p class="title">詳細說明</p><div id="v3f3by3" class="box"><p><p> 低溫下的機械密封 </p> <p> 在煉油化工裝置中，低溫輸送的介質一般都具有豁度小、潤滑性差、容易氣化的特點，而且介質在氣化時大量吸熱，使周圍溫度急劇下降，造成空氣中水氣的凝結，導致端面及其周圍結冰，使端面貼合不嚴引起泄漏。同時，因潤滑性差，端面摩擦產生的熱量較多，若不能及時轉移，必然會加劇端面處的氣化，造成惡性循環(huán)，加速密封面的早期失效。另外，鹽城容積泵密封哪家比較好，低溫密封的輔助密封圈在低溫下發(fā)硬失彈也容易導致泄漏。 </p> <p> <span style="font-size:12px;">對低溫密封，除了選擇合適的輔助密封圈材質外，還要注意以下幾點。</span> </p> <p> 改進密封結構及正確選擇摩擦副材料。實踐證明，在靜環(huán)表面開圓弧形凹槽可形成流體動力密封，增加流體膜承載能力，改善端面潤滑條件，有效延長機封工作壽命。在端面配對方面，碳化鎢一M106K石墨組對（即動、靜環(huán)材料）一般要優(yōu)于其他材料，鹽城容積泵密封哪家比較好，因為其潤滑性好，摩擦系數(shù)低，導熱性也比較好。 </p> <p> 選擇合適的端面比壓。低溫密封由于端面潤滑性差，鹽城容積泵密封哪家比較好，容易發(fā)生氣化、結冰，所以在保證密封可靠的前提下，端面比壓可適當減小。一般機械密封比壓值推薦為0.29-0.59MPa，對低溫密封可取其下限。對金屬波紋管機械密封，由于動環(huán)沒有軸向摩擦，端面比壓甚至可以低于下限。 </p> <p> <br /> 如果密封無法直接裝入到預定的位置，就需要對相關尺寸進行調整，避免硬裝現(xiàn)象的發(fā)生。鹽城容積泵密封哪家比較好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鹽城容積泵密封哪家比較好,封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247298179248047/5187331.jpg"></div><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 />

油封的骨架和彈簧是金屬制作，密封唇口等主要部分為橡膠。油封根據(jù)使用環(huán)境，可以用不同的橡膠進行生產，以滿足密封的性能和要求。**常用的耐油橡膠是丁腈橡膠，丁腈橡膠為目前油封及O型圈使用**普遍的橡膠之一。 </p> <p> <span style="font-size:12px;">可說是目前用途**廣、成本比較低的橡膠密封件。制造油封常用的還有聚丙酸酯橡膠、硅橡膠、氟橡膠和聚四氟乙烯等。各種橡膠的性能請參見：主要橡膠的種類與特長。 </span> </p> <p> <span style="font-size:12px;"> </span> </p> <p> 油封所使用的場合，其適用的密封介質一般是礦物潤滑油、潤滑脂和合成潤滑油、潤滑脂。另外也可密封工業(yè)生產中使用的DIN51524液壓油類，VDMA24317以及VDMA24320高阻燃液壓油類，低潤滑特性的硅油類。在特殊情況下也可密封潤滑性低的酸類，堿類，有機溶劑類等腐蝕性介質。 </p> <p> <span style="font-size:12px;">通常采用氟橡膠材料的油封其耐腐蝕性，耐高溫性都要比NBR材質的好，在無潤滑、純干燥和多介質的條件下建議采用PTFE密封唇制作的油封，其密封唇有足夠的潤滑能力，降低唇緣的磨損。單個油封不宜密封兩種不同的介質，大量的化學物質增加了對于油封材質性能的影響，油封對密封介質的相容性應該通過實驗室試驗來確定。</span> </p> <br /> <p> <br /> </p><p> <br /> </p> <p> 化工泵油封是一種自緊式唇狀密封，其結構簡單，尺寸小，成本低廉，維護方便，阻轉矩較小，既能防止介質泄漏，也能防止外部塵土和其它有害物質侵入，而且對磨損有一定的補償能力，但不耐高壓，所以一般用在低壓場合的化工泵上。 </p> <p> 化工泵依靠離心原理來抽取液體物料，特殊材料制成的化工泵適用于瓶、桶、缸、池或其他容器中抽取腐蝕性液體。由于化工泵所抽取的介質有腐蝕、揮發(fā)、等危險性的存在，對泵體的密封性能要求，要比其他種類的泵高很多。 </p> <p> 化工泵油封應安裝在制造精度為h8～h9，表面粗糙度為1.6～0.8μm且經過表面硬化處理的軸上。密封介質不應含有固體微粒和雜質，否則會造成油封和軸的迅速磨損而使密封失效。 </p> <p> 在選擇此種密封方法是，要充分考慮化工泵所輸送到物料的性能和要求，以避免不必要的泄漏，防止意外的發(fā)生。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 機械密封安裝調試好后，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。</p><div

為了不因選用串聯(lián)密封而增加成本，又能使高溫熱水泵安全可靠運行，建議選用單端面機械密封，沖洗方案可以選擇PLAN23+62。PLAN62 所通急冷液直接從23 冷卻器后引旁路連接至密封急冷口，具體流程見圖3 所示?？梢钥闯?，通過此種布置方式， PLAN62 不需要額外的配管將循環(huán)水引入密封急冷口，又能起到在密封失效時降低介質溫度，從而避免對人員的傷害，對系統(tǒng)加以保護。 </p> <p> <br /> 石墨炭化是使用碳-石墨環(huán)時密封失效的主要原因之一。常州水泵密封生產企業(yè)</p><p

機械密封彈簧壓縮量調試時有哪些要求？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，要用力均勻、對稱，分幾次擰完，不可一次緊定，以免偏斜，甚至壓碎石墨環(huán)。
