100多年來，人們采用填料一類的多種密封材料，使液體從液泵殼體沿著主軸的向外泄漏量不斷減少。盡管現(xiàn)代工藝流程中采用的液泵，仍然較大程度地沿用**古老的密封設(shè)計——填料盒，南京容積泵密封廠家批發(fā)，南京容積泵密封廠家批發(fā)，因為其起步費用低，而且又為工廠的工作人員所熟悉。 </p> <p> 然而，由于環(huán)境問題的關(guān)系，采用填料密封的方法已逐漸不能被人們所接受，特別是針對現(xiàn)代工藝流程中比較普遍的、腐蝕性較強的液體而言。因此，在實際應(yīng)用中，以機械密封代替填料密封的情況越來越多。 </p> <p> <br /> 設(shè)計輔助沖洗系統(tǒng)，南京容積泵密封廠家批發(fā)，沖洗壓力要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力因素來計算。南京容積泵密封廠家批發(fā)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

對石化行業(yè)來說，高溫重質(zhì)油泵用機械密封的選用一直是一大難題，例如催化裂化油漿泵、回?zé)捰捅?、常壓塔底泵、初餾塔底泵、減壓塔底泵、延遲焦化的輻射進料泵等。 </p> <p> 高溫重質(zhì)油泵的介質(zhì)具有以下共同的特點: </p> <p> 溫度高:一般在340一400℃; </p> <p> 介質(zhì)粘度大:在溫度下一般運動粘度為(12一180)X 10一6m/s; </p> <p> 介質(zhì)有顆粒:如催化劑、焦炭、含有砂粒等其他雜質(zhì)。 </p> <p> 對于高溫重油介質(zhì)泵用機械密封?，F(xiàn)在各個企業(yè)都采用焊接金屬波紋管械密封?，F(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結(jié)構(gòu)，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。南京化工泵密封軸彎曲變形時橫截面形心沿與軸線垂直方向的線位移稱為撓度，機械密封要求兩個密封端面之間受力均勻。</p><div

水泵出現(xiàn)滲水的部位主要是兩個部分，一是水泵的軸承密封件，一般此處漏是從水泵的溢流孔流出，此時需要更換水泵；二是水泵的也發(fā)動機結(jié)合部件的密封件，這里可以單獨更換此零件（提醒大家要注意避免“小病大治”）。 </p> <p> 水泵滲漏的原因：由于水泵設(shè)計原因，水泵軸承收到側(cè)面單邊力量過大，也就是皮帶輪側(cè)偏心力大，容易導(dǎo)致水泵軸承偏磨；加之大家平時急加速的和急收油等加速皮帶對水泵軸承的沖擊（這是從用的角度出發(fā)）；內(nèi)部缺水，水泵軸承得不到冷卻液的潤滑，也會導(dǎo)致密封件損壞（這是從養(yǎng)的角度出發(fā)）；防凍液長時間不更換，雜質(zhì)增加加速磨損（同樣也是養(yǎng)的問題）； </p><p> <p> 影響泵用機械密封的外部原因 </p> <p> 泵軸的軸向竄量 </p> 泵軸的撓度偏大 </p> <p> 沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)計不合理 </p> <p> 振動偏大及消除措施 </p> <p> <p> 泵氣蝕的原因及改進措施 </p> <p> <p> 在凝結(jié)過程中，由于體積急劇縮小，四周的液體以極大的速度沖向整個凝結(jié)空間，使泵內(nèi)造成沖擊振動和噪音。在壓力很大、頻率很高的液體質(zhì)點連續(xù)沖擊下，金屬表面逐漸因疲勞而破壞，這種破壞稱為剝蝕。 </p> <p> 同時溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機械剝蝕的共同作用，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進口氣蝕的措施有以下幾點： </p> <p> 提高泵的氣蝕性能水平，滿足現(xiàn)場裝置的氣蝕性能的要求。 </p> <p> 泵應(yīng)當(dāng)在低于允許吸液高度下操作，以保證整個裝置安全可靠的運轉(zhuǎn)。 </p> <p> 采用抗氣蝕材料制造葉輪，如：2Cr13、稀土合金鑄鐵、高鎳鉻合金材料等，比普通鑄鐵的抗氣蝕能力要好得多。 </p> <p> <br /> </p> <p> <br /> </p> </p> 軸封腔壓力很高或者壓力接近該密封使用比較高極限時，由密封腔引液體至低壓區(qū)，使軸封液體流動以帶走摩擦熱。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南京容積泵密封廠家批發(fā),封"

</p> <p> 可能的原因:表面不平;石墨密封面起泡;密封面產(chǎn)生熱變形 </p> <p> 解決方法:在安裝過程中，輔助密封被劃傷O形圈老化，由于壓縮形變輔助密封變硬變脆由于化學(xué)作用輔助密封變軟變粘 </p> <p> 現(xiàn)象:彈簧失效 </p> <p> 可能的原因:由于腐蝕作用，金屬附件損壞，傳動機構(gòu)被腐蝕 </p> <p> 解決方法:檢查不正確的安裝尺寸,檢查是否采用了不合適的材料和密封類型改進沖洗冷卻管線,檢查是否出現(xiàn)壓蓋螺栓扭矩過大導(dǎo)致壓蓋變形,檢查壓蓋墊片的比壓是否合適，檢查密封面間有無其他固體顆粒，如需要時對密封面重新拋光。檢查密封面處的裂紋，更換主、配合密封環(huán)。 </p> <p> 現(xiàn)象:操作過程中，密封發(fā)出尖嘯聲 </p> <p> 可能的原因:密封處的潤滑液量不足 </p> <p> 解決方法:增加旁路沖洗管線（如果沒有的話）擴大旁路沖洗管線和/或壓蓋上的開孔。密封面合理的間隙，機械密封的平衡程度，密封端面液膜的閃蒸都是造成端面打開而使固體顆粒進入的主要原因。南京容積泵密封廠家批發(fā)</p><p style="text-indent:25px">泵的密封對整個設(shè)備運轉(zhuǎn)來說起著重要的作用，泵的密封系統(tǒng)泄漏將會嚴重影響到設(shè)備的正常運轉(zhuǎn)。南京容積泵密封廠家批發(fā)</p><p> 化工泵密封墊片選擇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?；け贸Ｓ玫拿芊夥椒?，有墊片密封法。墊片是離心泵靜密封的基本元件，使用范圍非常***。墊片的選型主要根據(jù)化工泵輸送介質(zhì)、溫度、壓力和腐蝕性等因素決定。 </p> <p> 當(dāng)化工泵輸送介質(zhì)，對溫度和壓力不高時，一般選用非金屬密封墊片； </p> <p> 當(dāng)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(dāng)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(dāng)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(dāng)當(dāng)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 /> 南京容積泵密封廠家批發(fā)</p><p>
