一、選型方法機(jī)械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機(jī)械密封，耐高壓、耐腐蝕機(jī)械密封，耐顆粒介質(zhì)機(jī)械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機(jī)械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機(jī)械密封。選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。選型的基本原則為：1.根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。2.根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動(dòng)壓式或非接觸型。3.根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。4.根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。二、機(jī)械密封的安裝與使用要求1.機(jī)械密封對(duì)機(jī)器精度的要求（以泵用機(jī)械密封為例）（1）安裝機(jī)械密封部位的軸（或軸套）的徑向跳動(dòng)公差不超過～。（2）轉(zhuǎn)子軸向竄動(dòng)不超過。（3）密封腔體與密封端蓋結(jié)合的定位端面對(duì)軸（或軸套）表面的跳動(dòng)公差不超過～。2.密封件的確認(rèn)（1）確認(rèn)所安裝的密封是否與要求的型號(hào)一致。（2）安裝前要仔細(xì)地與總裝圖對(duì)照，零件數(shù)量是否齊全。。</p><p> 機(jī)械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機(jī)械基礎(chǔ)元件之一，是各種泵類、反應(yīng)合成釜、透平壓縮機(jī)、潛水電機(jī)等設(shè)備的關(guān)鍵部件。其密封性能和使用壽命取決于許多因素，如選型、機(jī)器的精度、正確的安裝使用等。機(jī)械密封件常識(shí)編輯機(jī)械密封件基本知識(shí)1、機(jī)械密封的基本概念：機(jī)械密封是指由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用下以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置。補(bǔ)償環(huán)的輔助密封為金屬波紋管的稱為波紋管機(jī)械密封。2、機(jī)械密封的組成：主要有以下四類部件。a.主要密封件：動(dòng)環(huán)和靜環(huán)。b.輔助密封件：密封圈。c.壓緊件：彈簧、推環(huán)。d.傳動(dòng)件：彈箕座及鍵或固定螺釘機(jī)械密封件應(yīng)注意問題1、安裝時(shí)注意事項(xiàng)a、要十分注意避免安裝中所產(chǎn)生的安裝偏差（1）上緊壓蓋應(yīng)在聯(lián)軸器找正后進(jìn)行，螺栓應(yīng)均勻上支，防止壓蓋端面偏斜，用塞尺檢查各點(diǎn)，其誤差不大于。（2）檢查壓蓋與軸或軸套外徑的配合間隙（即同心度），四周要均勻，用塞尺檢查各點(diǎn)允差不大于。b、彈簧壓縮量要按規(guī)定進(jìn)行，不允許有過大或過小現(xiàn)象，要求誤差。過大會(huì)增加端面比壓，另速端面磨損。過小會(huì)造成比壓不足而不能起到密封作用。廣東連成水泵機(jī)械密封。</p><div

8.沖洗方案31方案：從泵出口經(jīng)過旋流器清潔液體沖洗機(jī)封，離心分離的固體被送泵進(jìn)口。原因：機(jī)封腔除熱，從沖洗和密封腔中除去固體。場合：帶砂或管道渣子臟的或被污染流體或水，非聚合流體。維護(hù)：旋流器處理的**好比重是流體2倍的固體，密封腔的壓力必須接近或等于進(jìn)口壓力，以保證流量適中。管不應(yīng)該包括限流孔板，密封腔不開排氣孔典型故障:旋流器或管路堵塞，檢查管子末端溫度。9.沖洗方案32方案：用外部清潔源頭沖洗機(jī)封，應(yīng)慎重選擇沖洗液來源，消除注入液體蒸發(fā)，或被泵送液體污染。原因：密封腔除熱，從密封腔內(nèi)除去工藝流體或固體，增加密封腔壓力和流體汽化臨界范圍。場合：臟的或被污染的流體、紙漿，高溫條件，聚合物或氧化流體。維護(hù)：使用大小確定的喉部襯套來保持壓力或維護(hù)流體速度，限制臟的工藝流體，控制噴射流量，增加流體汽化臨界范圍，控制噴射壓力，噴射流體必須和工藝流體相容，經(jīng)常觀察控制系統(tǒng)，檢查閥門是否關(guān)閉和堵塞跡象。寶坻區(qū)連成水泵機(jī)械密封。云南連成水泵機(jī)械密封</p><p
