三、區(qū)分骨架油封型號C型骨架油封為內(nèi)骨架油封可分為SC型、TC型、VC型、KC型、DC型這五種，分別是單唇內(nèi)骨架油封、雙唇內(nèi)骨架油封、單唇無簧內(nèi)骨架油封、雙唇無簧內(nèi)骨架油封、雙唇雙簧內(nèi)骨架油封。G型骨架油封是外出有螺紋狀，其類型和C型一樣，只是在工藝上在外側(cè)修改成有螺紋狀，類似于O型圈的作用，即起到加強密封效果的作用，還能起到固定油封不松動。B型骨架油封是骨架內(nèi)側(cè)有膠料或者骨架內(nèi)外都沒有膠料，沒有膠料會讓散熱性能更好。A型骨架油封是裝配式油封，結(jié)構(gòu)相對上述三種相對復雜，特點是承壓性能更好更優(yōu)異。四、骨架油封的密封原理及應(yīng)用?骨架油封共分三部分：自緊彈簧、密封主體、加強骨架。?骨架油封的密封原理：由于在油封與軸之間存在著油封刃口控制的油膜，此油膜具有流體潤滑特性。?密封原理解析：骨架油封的作用下，油膜的剛度恰好使油膜與空氣接觸端形成一個新月面，防止了工作介質(zhì)的泄漏，從而實現(xiàn)旋轉(zhuǎn)軸的密封。油封的密封能力，取決于密封面油膜的厚度，厚度過大，油封泄漏；厚度過小，可能發(fā)生干摩擦，引起油封和軸磨損；密封唇與軸之間沒有油膜，則易引起發(fā)熱、磨損。因此，四川泵用機械密封廠，四川泵用機械密封廠，四川泵用機械密封廠，在安裝時，必須在密封圈上涂些油，同時保證骨架油封與軸心線垂直。天津格蘭富泵用機械密封型號。四川泵用機械密封廠</p><div

磨損較均勻；從受力角度考慮過窄不利，破壞和變形的可能性增加了＞俐，密封端面的直徑又是載荷系數(shù)的函數(shù)。因此，密封端面的寬度應(yīng)綜合考慮。一般地講，對普通介質(zhì)密封端面隨直徑的增大而加寬。對于輕烴類介質(zhì)，端面寬度比在普通介質(zhì)中寬一些：而高速機械密封，端面寬度相對地窄一些，否則發(fā)熱量太大，不能正常運轉(zhuǎn)，一般在3mm左右。環(huán)直徑（mm、環(huán)寬（mm）－20～602～460～1004～6100～2005—7四、密封環(huán)的技術(shù)要求：1）密封端面的平面度不大于0．0009mm（即三個單色光干涉帶）；硬質(zhì)材料密封端面粗糙度Ra值不大于0．2μm（相當于Δ10）；軟質(zhì)材料密封端面粗糙度Ra值不大于0．4μm(相當于Δ9)，表面不應(yīng)有裂紋、劃傷、氣孔和疏松等影響使用性能的缺陷。2）密封環(huán)的密封端面與輔助密封圈接觸的端面平行度按GBll84－80的7級精度規(guī)定。3）密封環(huán)端面與安裝輔助密封圈的內(nèi)（或外）圓表面的垂直度應(yīng)按GBll84－80的7級精度的規(guī)定。4）密封環(huán)與輔助密封圈接觸部位的表面粗糙度凡值不大于3．2μm；外圓或內(nèi)孔尺寸公差為hg或Hg。上述要求是對普通泵用機械密封的密封環(huán)而言，對轉(zhuǎn)速較低的釜用機械密封可適當放寬或參考相應(yīng)的標準，而對高速機械密封則要求更高。五、平面度平面度。四川泵用機械密封廠嘉峪關(guān)襄樊五二五泵用機械密封選型。</p><div

尤其是深度尺寸過大時，使O形圈安裝后壓縮變形量不足而影響密封能力。一般O形圈安裝后壓縮變形量應(yīng)在18%～22%之間，截面尺寸大時壓縮相對變形量較小，而截面尺寸較小時壓縮相對變形量則較大。2、O形密封圈的公稱尺寸與實際安裝尺寸相差太多，形成O形圈在拉伸后截面尺寸縮小的狀況下工作，造成壓縮變形量不足而產(chǎn)生泄漏。3、O形密封圈在安裝時，由于密封面的進口沒有光滑的倒角或倒圓而將O形圈劃傷而產(chǎn)生泄漏。4、O形密封圈的材質(zhì)不適用于密封介質(zhì)而被侵蝕后失效。5、O形密封圈使用時間太久后老化變質(zhì)，彈性降低后而失效，所以在設(shè)備大修時一般都將O形圈更換。另外，O形密封圈的硬度，溝槽和密封面的粗糙度也影響O形密封圈的密封效果。填料密封將富有壓縮性和回彈性的填料放入填料函內(nèi)，依靠壓蓋的軸向壓緊力轉(zhuǎn)化為徑向密封力，從而起到密封作用。這種密封方法稱為填料密封，這種填料稱為密封填料。由于填料密封結(jié)構(gòu)形式簡單，更換方便、價格低廉、適應(yīng)轉(zhuǎn)速、壓力、介質(zhì)寬泛而在泵的設(shè)計中得到普遍采用。輸送常溫介質(zhì)時，填料密封一般都設(shè)有填料環(huán)，其或與泵的高壓腔相通，或外接具有一定壓力的液體介質(zhì)，可起到冷卻、潤滑、密封或沖洗作用。由于填料密封是一種接觸密封。</p><p> 3)先將靜環(huán)與壓蓋一起裝在軸上，注意不要與軸相碰，然后將動環(huán)組件裝入。彈簧座或傳動座的緊定螺釘應(yīng)分幾次均勻擰緊。在未固定壓蓋之前，用手推補償環(huán)作軸向壓縮，松開后補償環(huán)能自動彈回無卡滯現(xiàn)象，然后將壓蓋螺拴均勻地鎖緊。4.使用(1)當輸送介質(zhì)溫度偏高、過低、或含有雜質(zhì)顆粒、易燃、易爆、有毒時，必須采取相應(yīng)的阻封、沖洗、冷卻、過濾等措施。(2)運轉(zhuǎn)前用手盤車，注意轉(zhuǎn)矩是否過大，有無擦碰及不正常的聲音。(3)注意旋向，聯(lián)軸器是否對中，軸承部位的潤滑油加法是否適當，配管是否正確。(4)運轉(zhuǎn)前首先將介質(zhì)、冷卻水閥門打開，檢查密封腔內(nèi)的氣體是否全排出，防止靜壓引起泄漏，然后開機運行。(5)開車后工作是否正常穩(wěn)定，有無因軸轉(zhuǎn)動引起的異常轉(zhuǎn)矩，以及異常響聲和過熱現(xiàn)象。三、主要技術(shù)結(jié)構(gòu)和解決方法這些泵的機械密封是由兩塊垂直于軸的密封元件(靜環(huán)和動環(huán))組成的，其表面光潔而平直，相互貼合。密封端面平面度不大于，表面粗糙度，金屬材料Ra=μm，非金屬材料Ra=μm。動環(huán)和靜環(huán)作相對轉(zhuǎn)動，摩擦副材料為石墨、氧化鋁陶瓷、碳化硅、氮化硅、碳化鎢硬質(zhì)合金等。工作時，靠彈簧和密封介質(zhì)(工作溶液)的壓力在旋轉(zhuǎn)的動環(huán)和靜環(huán)的接觸表面上產(chǎn)生適當?shù)膲壕o力。寶雞渣漿泵用機械密封泄露。</p><div

五、與釜用機械密封有關(guān)的幾個參數(shù)1.使用壽命釜用機械密封的使用壽命一般規(guī)定半年以上.其實使用壽命與攪拌軸的轉(zhuǎn)速、密封尺寸、摩擦副材料等因素有關(guān).圖10-6為EKATO公司對不同尺寸的密封在不同轉(zhuǎn)速下的使用壽命試驗結(jié)果.2.適用范圍釜用密封的適用范圍與使用條件、何種輔助裝置有關(guān)，，每個密封公司都有其產(chǎn)品適用范圍的說明.圖10-7為EKATO公司RD023和RD200ST型密封在密封液貯罐和壓力平衡裝置兩種條件下的適用范圍圖.高溫機械密封機械密封的工作溫度超過80℃時就作為高溫機械密封(有的密封公司以工作溫度>90℃為界限)，在高溫下，密封主要間題有下列幾項:密封端面液體汽化，摩擦副的熱應(yīng)力和熱變雍，組合件、鑲嵌件可能因配合不當而松脫，輔助密封圈因高溫引起的老化、龜裂、粘結(jié)和彈性消失，彈簧疲勞和強度降低，材料的腐蝕和磨損加快.一、高溫機械密封的要求1.選用耐高溫的密封材料在高溫下，材料的耐溫性能顯得特別重要，合理選用密封材料可使一般結(jié)構(gòu)的機械密封仍能適用于高溫工作條件，簡化手續(xù)，節(jié)省開支.表10-1列出不同密封材料的使用極限溫度.2.采用金屬波紋管型機械密封或金屬波紋管與普通機械密封相結(jié)合的密封結(jié)構(gòu)從耐熱性能來看。綿陽飛力泵用機械密封泄露。LCP125-400泵用機械密封</p><p

專門進行詳細介紹。四、機械密封泄漏的原因分析新安裝(或更換)的機械密封投入運轉(zhuǎn)時泄漏量應(yīng)在允許范圍內(nèi)。如果密封本身的結(jié)構(gòu)、制造質(zhì)量、安裝和使用等方面都無問題，其壽命要超過8000h。實際工作中，不少密封的使用壽命遠沒有達到該值前就失效了，這是由于工藝條件、設(shè)備運行狀況和操作存在一定的問題造成的。根據(jù)近幾年來機械密封運行工況和失效后的拆檢情況來看，其常見原因如下：1、密封環(huán)熱裂紋機械密封拆開時可發(fā)現(xiàn)，硬環(huán)表面有過熱回火色，石墨環(huán)表面有環(huán)狀溝紋、橡膠圈老化等。主要原因是：①由于介質(zhì)溫度過高泵體內(nèi)形成汽蝕，汽蝕發(fā)生后，水力沖擊帶動密封做迅速的軸向振蕩，使動靜環(huán)及輔助密封圈等零件嚴重的磨損，使機械密封裝置損壞。②潤滑不良，密封環(huán)端面沒有形成液體潤滑膜或密封環(huán)端面間液膜汽化，形成干摩擦；③冷卻系統(tǒng)散熱不良；2、離心泵的振動由于制造和安裝精度等原因，所有的離心泵都存在著振動。振動的原因主要為轉(zhuǎn)子不平衡、機泵不同心、滾動軸承故障等。從軸承箱表面測到的大振幅不能大于，超過該值就要停泵處理。振動可分解為三個方向：垂直、水平和軸向，其中以軸向振動對密封的危害大。當泵振動加劇時，動靜環(huán)之間發(fā)生分離。四川泵用機械密封廠</p></p><br
