一、機(jī)械密封概述機(jī)械密封（端面密封）是一種用來(lái)解決旋轉(zhuǎn)軸與機(jī)體之間密封的裝置。它是由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面的流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用及輔助密封的配合下保持貼合下并相對(duì)滑動(dòng)而構(gòu)成防止流體泄漏的裝置，常用于泵、壓縮機(jī)、反應(yīng)攪拌釜等旋轉(zhuǎn)式流體機(jī)械，也用于齒輪箱、船舶尾軸等密封。因此，機(jī)械密封是一種通用的軸封裝置。機(jī)械密封結(jié)構(gòu)多種多樣，常用的機(jī)械密封結(jié)構(gòu)是端面密封。端面密封的靜環(huán)、動(dòng)環(huán)組成一對(duì)摩擦副，摩擦副的作用是防止介質(zhì)泄漏。它要求靜環(huán)、動(dòng)環(huán)，具有良好的耐磨性，動(dòng)環(huán)可以在軸向靈活的移動(dòng)，自動(dòng)補(bǔ)償密封面磨損，使之與靜環(huán)良好的貼合；靜環(huán)具有浮動(dòng)性，起緩沖作用。為此，密封面要求有良好的加工質(zhì)量，保證密封副有良好的貼合性能。構(gòu)成機(jī)械密封的基本元件有靜環(huán)、動(dòng)環(huán)、壓蓋、推環(huán)、彈簧、定位環(huán)、軸套、動(dòng)環(huán)密封圈、靜環(huán)密封圈軸套密封圈等。彈性元件（彈簧、波紋管）它主要起預(yù)緊、補(bǔ)償和緩沖的作用，要求始終保持足夠的彈性來(lái)克服輔助密封和傳動(dòng)件的摩擦和動(dòng)環(huán)等的慣性，保證端面密封副良好的貼合和動(dòng)環(huán)的追隨性，材料要求耐腐蝕、耐疲勞。輔助密封。</p><p> 主要決定于填料壓蓋的壓緊力。壓力大可提高密封效果，但卻會(huì)加大動(dòng)力消耗和軸套的磨損，反之則會(huì)產(chǎn)生較大泄漏。因此應(yīng)根據(jù)泄漏量大小和泄漏介質(zhì)的溫度對(duì)壓蓋的壓緊力進(jìn)行調(diào)整，必要時(shí)應(yīng)對(duì)填料進(jìn)行更換或補(bǔ)充。填料密封的合理泄漏一般為10-20ml/min。當(dāng)從外界引入液體時(shí)，應(yīng)保證這種液體有良好的化學(xué)穩(wěn)定性，既不污染泵所輸送的介質(zhì)，又不與介質(zhì)發(fā)生反應(yīng)產(chǎn)生沉淀物和固體微粒，還應(yīng)與填料有良好的浸漬性和持久的保持性，這樣就能起到良好和持久的密封效果。動(dòng)力密封副葉輪加停車(chē)密封泵在運(yùn)轉(zhuǎn)時(shí)，副葉輪所產(chǎn)生的壓頭平衡了主葉輪出口高壓液體，從而實(shí)現(xiàn)密封。停車(chē)時(shí)，副葉輪不起作用，因此必須同時(shí)配備停車(chē)密封裝置解決停車(chē)時(shí)可能產(chǎn)生的泄漏。副葉輪密封結(jié)構(gòu)簡(jiǎn)單、密封可靠、使用壽命長(zhǎng)，運(yùn)轉(zhuǎn)中可實(shí)現(xiàn)滴水不漏，因此在輸送含雜質(zhì)介質(zhì)的泵上經(jīng)常采用。副葉輪良好的密封效果是有條件的，即工作壓力不允許超過(guò)允許的工作壓力。一旦超過(guò)，會(huì)產(chǎn)生嚴(yán)重的泄漏。工作壓力變化的主要原因是泵吸入口的壓力變化，因此采用副葉輪密封的泵，必須對(duì)泵的進(jìn)口壓力做出嚴(yán)格的規(guī)定，否則密封便會(huì)失效。由于停車(chē)密封的形式很多，失效后也容易發(fā)現(xiàn)，本文不再贅述。河北格蘭富機(jī)械密封件。</p><div
