但彈簧和波紋管可補(bǔ)償液泵在起動(dòng)和停機(jī)過(guò)程中因主軸運(yùn)動(dòng)的壓力不足，使密封面始終保持一定的密封壓力。腐蝕磨損問(wèn)題由于多種原因，例如包括軸承的公差、軸端余隙、振動(dòng)和主軸偏差，都會(huì)使液泵的主軸產(chǎn)生徑向和軸向運(yùn)動(dòng)。此外，由于將接觸面之間保持相對(duì)平行是十分困難的，因此機(jī)械密封本身的內(nèi)部產(chǎn)生移動(dòng)也是很正常的。這類移動(dòng)往往是由于設(shè)備和安裝公差、熱膨脹、管路應(yīng)力或主軸調(diào)試不當(dāng)所造成。為了使密封面之間始終保持互相配合，彈簧起到了機(jī)械密封與運(yùn)動(dòng)主軸之間的恒定調(diào)節(jié)作用。當(dāng)旋轉(zhuǎn)面和主軸之間采用人造橡膠密封時(shí)，該彈性體就會(huì)在主軸上來(lái)回運(yùn)動(dòng)。這種重復(fù)摩擦動(dòng)作，會(huì)磨蝕主軸上的防腐材料，失去主軸的氧化膜保護(hù)層，終會(huì)在主軸的摩擦面上形成磨損溝槽，造成液體從溝槽中泄漏，并增加必要的維修工作量或甚至更換主軸。為了解決這一問(wèn)題，一般在填料盒內(nèi)安裝一個(gè)可更換的軸套。然而，解決腐蝕磨損問(wèn)題的辦法是去除其內(nèi)部的動(dòng)態(tài)密封?，F(xiàn)在，大部分主要密封制造廠生產(chǎn)非腐蝕磨損型密封，以防止液泵零件的腐蝕磨損。平衡和非平衡式密封機(jī)械密封的平衡對(duì)接觸面的密封壓力有很大影響。這一密封壓力取決于密封本身的有效截面以及填料盒內(nèi)的壓力。南通機(jī)械密封大全合肥橡膠波紋管機(jī)械密封件。</p><div

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。廈門(mén)機(jī)械密封系列</p><p
