填料密封是靠盤(pán)根的壓緊在軸上或軸套上起作用的。填料密封與軸直接摩擦，填料壓的越緊摩擦力就越大、消耗功率也就越大。而機(jī)械密封的摩擦是處于半液摩擦狀態(tài)，摩擦系數(shù)非常的小，機(jī)械密封的功率損失是填料密封的10～50%（6）波紋管密封軸或軸套不受磨損，對(duì)旋轉(zhuǎn)軸的振擺和軸對(duì)殼體的偏斜不敏感。（7）適用范圍廣。當(dāng)介質(zhì)易燃、易爆、有毒有害時(shí)，采用機(jī)械密封可保證密封。它還適用于高溫、低溫、高壓、真空各種轉(zhuǎn)速的及腐蝕介質(zhì)的設(shè)備密封。2、缺點(diǎn)（1）如結(jié)構(gòu)比填料密封復(fù)雜，加工精度要求高，并要求一定的安裝技術(shù)等，特別是干氣密封的安裝要求更高。而且密封技術(shù)發(fā)展的很快，新技術(shù)不斷出現(xiàn)給我們維修帶來(lái)了新的課題。（2）結(jié)構(gòu)復(fù)雜、拆裝不便。與其它密封比較，機(jī)械端面密封的零件數(shù)目多，要求精密，結(jié)構(gòu)復(fù)雜。特別是在裝配方面較困難，拆裝時(shí)要從軸端抽出密封環(huán)，必須把機(jī)器部分（聯(lián)軸器）或全部拆卸。這一問(wèn)題目前已作了某些改進(jìn)，例如采用拆裝方便并可保證裝配質(zhì)量的剖分式和集裝式機(jī)械密封等。三、機(jī)械密封的工作原理機(jī)械密封亦稱端面密封，是靠一對(duì)或數(shù)對(duì)垂直于軸作相對(duì)滑動(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。</p><p>
