</p> <p> 當化工泵輸送介質(zhì)為中壓高溫時，選用非金屬與金屬組合墊片。 </p> <p> 非金屬墊片在泵上應(yīng)用**為普遍，其材料一般為紙、橡膠和聚四氟乙烯。當溫度不超過120℃，壓力在1.0Mpa以下時，一般選用青殼紙或模造紙墊片。 </p> <p> 如果當化工泵輸送介質(zhì)為油，溫度在-30～110℃時，一般選用耐老化性能較好的丁晴橡膠。當當化工泵輸送介質(zhì)，在-50～200℃時，選用氟橡膠更為合適。因為它除了耐油耐熱外，機械強度大也是其主要特征。 </p> <p> 在化工泵中由于所輸送介質(zhì)具有腐蝕性，所以一般選用聚四氟乙烯做為墊片材料。隨著化工泵使用的領(lǐng)域越來越多次，所輸送介質(zhì)種類也越來越多，因此在選用墊片材質(zhì)時應(yīng)查閱相關(guān)資料或通過實驗后再做出正確選擇。 </p> <p> <br /> </p><p> 填料密封的原理 </p> <p> 在機械行業(yè)中填料密封主要用作動密封,常用作離心泵、壓縮機、真空泵、攪拌機的轉(zhuǎn)軸密封。填料裝入填料腔以后,經(jīng)壓蓋螺絲對它作軸向壓縮,當軸與填料有相對運動時,由于填料的塑性,使它產(chǎn)生徑向力,并與軸緊密接觸。與此同時,填料中浸漬的潤滑劑被擠出,在接觸面之間形成油膜。由于接觸狀態(tài)并不是特別均勻的,接觸部位便出現(xiàn) </p> <p> 邊界潤滑狀態(tài),稱為”軸承效應(yīng)”;而未接觸的凹部形成小油槽,有較厚的油膜,接觸部位與非接觸部位組成一道不規(guī)則的迷宮,起阻止液流泄漏的作用,此稱”迷宮效應(yīng)”。這就是填料密封的機理。良好的密封在于維持“軸承效應(yīng)”和”迷宮效應(yīng)”。也就是說,要保持良好的潤滑和適當?shù)膲壕o，若潤滑不良,或壓得過緊都會使油膜中斷,造成填料與軸之間出現(xiàn)干摩擦,而后導致燒軸和出現(xiàn)嚴重磨損。因此,我們需要經(jīng)常對填料的壓緊程度進行調(diào)節(jié),使填料中的潤滑劑在運行一段時間而有所流失之后,再擠出一些潤滑劑,同時補償填料因體積變化所造成的壓緊力松弛。當然這樣經(jīng)常擠壓填料,而后將使浸漬劑枯竭,所以定期更換填料是必要的。此外,為了維持液膜和帶走摩擦熱,有意讓填料處有少量泄漏也是必要的。人們在分析機械密封泄漏原因時，在機械封自身方面查找原因，比如：它的選型如是否合適，材料選擇是否正確。</p><div

src="https://tyunfile.71360.com/UploadFile/lscmjx/637247298359511719/4792927.jpg"></div><p> 化工泵油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)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(zhì)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(yīng)安裝在制造精度為h8～h9，表面粗糙度為1.6～0.8μm且經(jīng)過表面硬化處理的軸上。密封介質(zhì)不應(yīng)含有固體微粒和雜質(zhì)，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> 造成油封漏油的主要因素： </p> <p> 油封密封不嚴是造成漏油的主要因素。當軸出現(xiàn)磨損形成溝槽，即使更換新油封仍不能密封時，是由于油封唇口與軸的接觸壓力下降，造成安裝后油封唇直徑與軸徑的過盈量太小。 </p> <p> 現(xiàn)以S195型柴油機曲軸油封為例，分析其密封不嚴的主要原因是：油封制造質(zhì)量差軸或軸承質(zhì)量差使用維護不當安裝不當保管不當，受環(huán)境污染造成不良影響 </p> <p> <br /> 機械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護密封面，起到冷卻、潤滑、沖走雜物等作用。鹽城電動泵密封源頭直供廠家</p><p style="text-indent:25px">機械密封的正常運行必須具備以下條件：泵軸的竄量不能太大。鹽城電動泵密封源頭直供廠家</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(zhì)一般都具有豁度小、潤滑性差、容易氣化的特點，而且介質(zhì)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(jié)，導致端面及其周圍結(jié)冰，使端面貼合不嚴引起泄漏。同時，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時轉(zhuǎn)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，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(zhì)外，還要注意以下幾點。</span> </p> <p> 改進密封結(jié)構(gòu)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，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，容易發(fā)生氣化、結(jié)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 /> 鹽城電動泵密封源頭直供廠家</p><p
