機械密封又稱端面密封(Mechanical seal)，是旋轉(zhuǎn)軸用動密封。機械密封性能可靠，泄露量小，使用壽命長，功耗低。毋須經(jīng)常維修，且能適應(yīng)于生產(chǎn)過程自動化和高溫，低溫，高壓，真空，高速以及各種強腐蝕性介質(zhì)。含固體顆粒介質(zhì)等苛刻工況的餓密封要求。機械密封是靠一對或幾對垂直于軸作相對潤動的端面在流體壓力和補償機構(gòu)的彈力(或磁力)作用下保持接合并配以輔助密封而達到的阻漏的軸封裝置。齒輪油泵對機械密封的要求，機械密封與軟填料密封比較如下：
機械密封優(yōu)點
1)密封可靠，在*運轉(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，在油，水介質(zhì)中一般可達1～2年或更長。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。端面磨損后可自動補償，一般情況下不需要經(jīng)常性維修：
6)抗震性好，對旋轉(zhuǎn)軸的振動以及軸對密封腔的偏斜不敏感：
7)適用范圍廣，機械密封能用于高溫，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。
機械密封缺點
1)較復(fù)雜，對加工要求高
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，處理較困難。
機械密封價高密封前的準(zhǔn)備工作：
1)檢查機械密封的型號。規(guī)格是否合設(shè)計圖紙的要求，所以零件(特別是密封面，輔助密封圈)有無損傷。變形。裂縫等現(xiàn)象，若有缺陷，必須更換或修復(fù)。
2)檢查機械密封各零件的配合尺寸，粗糙度，平行度是否符合設(shè)計要求。
3)使用小彈簧機械密封時，應(yīng)檢查小彈簧的長短和剛性是否相同。
4)檢查主機的竄動量。擺動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：軸竄動量不大于±0.5mm：軸擺動量(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。
