機(jī)械密封的拆卸過程1.關(guān)閉設(shè)備，按正確的程序冷卻和卸壓；2.沒有介質(zhì)接觸密封。如必要時(shí)，將設(shè)備內(nèi)介質(zhì)排空。3.采取措施，防止疏忽時(shí)設(shè)備的啟動(dòng)。為了正確地分析機(jī)械密封損壞和失效的原因，集裝式密封在取下時(shí)或取下后不應(yīng)被拆卸和清洗。當(dāng)密封在操作中或帶壓的情況下對(duì)密封的任何操作都是不允許的。從設(shè)備上拆卸和取下密封的順序由設(shè)備的設(shè)計(jì)和設(shè)備制造商決定，貼圖解釋一下。下圖為時(shí)***行的API682集裝密封若拆卸此密封，一般流程為：1.安裝止動(dòng)墊片至圖紙位置，擰緊螺栓；2.松開扭矩傳遞環(huán)上的緊定螺釘；3.松掉沖洗接管，松開壓蓋上的緊固件；4.取出機(jī)械密封。機(jī)械密封的安裝安裝前的準(zhǔn)備工作1.檢驗(yàn)機(jī)械密封是否完好。2.檢查傳動(dòng)件和配合件；3.檢查傳動(dòng)銷、定位銷在孔或槽中的配合；4.檢查定位螺釘?shù)臓顩r；5.使用小彈簧機(jī)械密封時(shí)，應(yīng)檢查小彈簧的長(zhǎng)度和剛性是否相同；安裝方法隨機(jī)械密封型式、機(jī)器的種類不同而有所不同，但其安裝要領(lǐng)幾乎都相同。以下為普通機(jī)械密封的安裝（非集裝密封）。安裝步驟和注意事項(xiàng)如下：⑴位置的確定安裝機(jī)械密封的工作長(zhǎng)度根據(jù)總裝圖要求，彈簧的壓縮量取決于彈簧座在軸上的定位尺寸。在確定其安裝位置之前。</p><p> 防止將工具、多余零件密封在箱殼之中造成事故。（三）裝配工作中的密封性在機(jī)械使用中，由于密封失效，常常出現(xiàn)"三漏"（漏油、漏水、漏氣）現(xiàn)象。這種現(xiàn)象輕則造成能量損失，以至降低或喪失工作能力，造成環(huán)境污染，重則可能造成嚴(yán)重事故。因此，防止"三漏"極為重要。流體漏損的原因可能由于密封裝置的裝配工藝不符合要求，也可能是由于密封件被磨損、變形、老化、腐蝕所至，而后者也往往與裝配因素（包括選用密封件材料、預(yù)緊程度、裝配位置等）有關(guān)。為此，在裝配工作中必須給以足夠的重視。1、選用密封材料要恰當(dāng)一般要根據(jù)不同的壓力、溫度、介質(zhì)選用。紙質(zhì)墊片只用于低壓、低溫條件；橡膠耐壓、耐溫能力也不高，且要考慮各種橡膠的不同性能，如耐油、耐酸、耐堿等；塑料的耐壓能力較好，但也不耐高溫；石棉強(qiáng)度較低，卻能耐高溫；金屬則兼有耐高溫、高壓的能力。2、合理裝配.要有合適的裝配緊度，并且壓緊要均勻。當(dāng)壓緊度不足時(shí)，會(huì)引起泄漏，或者在工作一段時(shí)間后，由于振動(dòng)及緊定螺釘被拉長(zhǎng)而喪失緊度，導(dǎo)致泄漏；壓緊度過緊，對(duì)靜密封的墊片來講，會(huì)喪失彈力，引起墊片早期失效；對(duì)動(dòng)密封來講，會(huì)引起發(fā)熱、加速磨損、增大摩擦功率等不良后果?；⑶饏^(qū)泵用機(jī)械密封件。</p><div
