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(zhuǎn)、延長使用壽命所必不可少的。 </p> <p> 強化潤滑的結(jié)構(gòu) </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(yīng)盡可能把氣體介質(zhì)條件轉(zhuǎn)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(yīng)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，南京葉輪泵密封源頭直供廠家，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(zhuǎn)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，南京葉輪泵密封源頭直供廠家。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(zhuǎn)時不斷帶入潤滑液至滑動面間起潤滑作用。 </p> <p> <br /> </p> 為了比較大發(fā)揮機械密封的實際性能，應(yīng)對密封環(huán)的使用進行調(diào)查，掌握其工作壓力，南京葉輪泵密封源頭直供廠家、溫度等情況，合理進行選擇。南京葉輪泵密封源頭直供廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">微型水泵能在不加引水的情況下，可以吸水，就表示這個水泵有自吸的功能?？沙槿∷?、液體(溶液)，適用于需要進行液體轉(zhuǎn)移、提升、清洗、噴灑、沖洗、灌溉等等多種場合。水泵的抽水管內(nèi)是空氣的情況下，利用泵工作時形成的負壓（真空），在大氣壓的作用下將低于抽水口的水壓上來，再從水泵的排水端排出。這個過程前是不需要加“引水（引導用的水）”的。就是說具備這種自吸能力的微型水泵，就叫“微型自吸水泵”。簡稱：“微型吸泵”原理類似微型真空泵。南京容積泵密封廠家推薦針對密封實際應(yīng)用中出現(xiàn)的問題，應(yīng)引起重視，分析問題發(fā)生的原因，然后及時采取針對性的措施，保證效果。</p><div

種布置方式(背靠背或面對面)。O 形圈材料選用耐腐蝕的氟橡膠或全氟橡膠。動靜環(huán)選用硬對硬(碳化鎢或碳化硅)配置。 </p> <p> 強酸強堿泵現(xiàn)場大多采用單端面密封，因而密封背面大多出現(xiàn)結(jié)晶結(jié)垢，對設(shè)備造成腐蝕等現(xiàn)象。為了避免該現(xiàn)象發(fā)生，使現(xiàn)場更加清潔，可直接選用PLAN54(見圖4)。煉油裝置中大多數(shù)酸泵或堿泵的入口壓力較低，基本為常壓，因此PLAN54 的沖洗源可直接用循環(huán)水。該方案雖然選用了雙端面密封，但從經(jīng)濟角度考慮*增加了一對摩擦副，沒有另外增加輔助系統(tǒng)，既節(jié)約了投資成本又滿足了現(xiàn)場要求。 </p><p> 隨著工業(yè)技術(shù)和密封技術(shù)的發(fā)展，泵在電力、化工、石油等多個行業(yè)大量使用，對泵密封的密封性和可靠性要求更高、更嚴?；け玫拿芊鈱φ麄€設(shè)備運轉(zhuǎn)來說起著重要的作用，化工泵的密封系統(tǒng)泄漏將會嚴重影響到設(shè)備的正常運轉(zhuǎn)。尤其是高溫高壓泵的發(fā)展,更使得對泵的密封更加嚴格。化工泵泄漏點 </p> <p> 泵用機械密封種類繁多，型號各異，但泄漏點主要有五處： </p> <p> 軸套與軸間的密封動環(huán)與軸套間的密封動、靜環(huán)間密封對靜環(huán)與靜環(huán)座間的密封密封端蓋與泵體間的密封 </p> <p> 現(xiàn)象：操作中密封發(fā)出爆裂聲（端面爆裂聲） </p> <p> 可能的原因：密封液在密封界面汽化；加強密封面的冷卻 </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。 </p> <p> 現(xiàn)象：密封連續(xù)滴漏 </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作用輔助密封變軟變粘。 </p> <p> 現(xiàn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 熱裂是高溫油泵，如油渣泵、回煉油泵、常減壓塔底泵等最常見的失效現(xiàn)象。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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> 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。南京容積泵密封廠家推薦</p><p style="text-indent:25px">根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。南京葉輪泵密封源頭直供廠家</p><p> 機械密封處滲©水的第一種可能性是機封的動、靜環(huán)平面磨損。而造成機封的動、靜環(huán)平面磨損的原因有六個方面： </p> <p> 原因一、安裝過緊。觀察機械密封的動靜環(huán)平面，如有嚴重燒焦現(xiàn)象，平面發(fā)黑和很深的痕跡，密封橡膠變硬，失去彈性，這種現(xiàn)象是由于安裝過緊造成的。 </p> <p> 處理辦法：調(diào)整安裝高度，葉輪發(fā)裝后，用螺絲刀拔動彈簧，彈簧有較強的張力，松開后即復(fù)λ，有24MM的移動距離即可。 </p> <p> 原因二、安裝過松。觀察機封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無磨損，這是彈簧失去彈性及裝配不良造成，或電機軸向竄動造成。 </p> <p> 原因三、水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。 </p> <p> 處理辦法：改進水壓或介質(zhì)，更換機封。 </p> <p> 原因四、缺水運行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進口處負壓，進水管有空氣，泵腔內(nèi)有空氣，泵開機后，機封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫，無法得到冷卻，檢查機封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機械密封。南京葉輪泵密封源頭直供廠家</p><p
