 機(jī)械密封又稱端面密封(Mechanical seal)，是旋轉(zhuǎn)軸用動(dòng)密封。機(jī)械密封性能可靠，泄露量小，使用壽命長(zhǎng)，功耗低。毋須經(jīng)常維修，且能適應(yīng)于生產(chǎn)過(guò)程自動(dòng)化和高溫，低溫，高壓，真空，高速以及各種強(qiáng)腐蝕性介質(zhì)。含固體顆粒介質(zhì)等苛刻工況的餓密封要求。機(jī)械密封是靠一對(duì)或幾對(duì)垂直于軸作相對(duì)潤(rùn)動(dòng)的端面在流體壓力和補(bǔ)償機(jī)構(gòu)的彈力(或磁力)作用下保持接合并配以輔助密封而達(dá)到的阻漏的軸封裝置。齒輪油泵對(duì)機(jī)械密封的要求，機(jī)械密封與軟填料密封比較如下：
    機(jī)械密封優(yōu)點(diǎn)     
    1)密封可靠，在*運(yùn)轉(zhuǎn)中密封狀態(tài)很穩(wěn)定，泄露量很小，其泄露約為軟填料密封的1%：
    2)使用壽命長(zhǎng)，在油，水介質(zhì)中一般可達(dá)1～2年或更長(zhǎng)。在化工介質(zhì)中一般工作半年以上：
    3)擦功率消耗小，其摩擦功率僅為軟填料密封的10%～50%
    4)軸或軸套基本上不摩損：
    5)維修周期長(zhǎng)。端面磨損后可自動(dòng)補(bǔ)償，一般情況下不需要經(jīng)常性維修：
    6)抗震性好，對(duì)旋轉(zhuǎn)軸的振動(dòng)以及軸對(duì)密封腔的偏斜不敏感：
    7)適用范圍廣，機(jī)械密封能用于高溫，低溫，高壓，真空，不同旋轉(zhuǎn)頻率，以及各種腐蝕介質(zhì)和含磨粒介質(zhì)的密封。
    機(jī)械密封缺點(diǎn)
    1)較復(fù)雜，對(duì)加工要求高
    2)安裝與更換比較麻煩，要求工人有一定的技術(shù)水平。
    3)發(fā)生偶然性事故時(shí)，處理較困難。
    機(jī)械密封價(jià)高密封前的準(zhǔn)備工作：
    1)檢查機(jī)械密封的型號(hào)。規(guī)格是否合設(shè)計(jì)圖紙的要求，所以零件(特別是密封面，輔助密封圈)有無(wú)損傷。變形。裂縫等現(xiàn)象，若有缺陷，必須更換或修復(fù)。
    2)檢查機(jī)械密封各零件的配合尺寸，粗糙度，平行度是否符合設(shè)計(jì)要求。
    3)使用小彈簧機(jī)械密封時(shí)，應(yīng)檢查小彈簧的長(zhǎng)短和剛性是否相同。
    4)檢查主機(jī)的竄動(dòng)量。擺動(dòng)量和繞度是否符合技術(shù)要求，密封腔是否符合安裝尺度，密封端蓋與軸是否垂直，一般要求：軸竄動(dòng)量不大于±0.5mm：軸擺動(dòng)量(旋轉(zhuǎn)環(huán)密封圈處)不大于0.06mm：軸zui大繞度不大于0.05mm：密封端蓋與墊片接觸平面對(duì)中心線的不垂直度允許差0.03～0.05mm。
    5)應(yīng)保持清潔，特別是旋轉(zhuǎn)環(huán)和靜止環(huán)密封面及輔助密封圈表面應(yīng)無(wú)雜質(zhì)、灰塵，不允許用不清潔的不檫拭密封面。
    6)不允許用工具敲擊密封元件，以防止密封件被損壞。
