填料密封是靠盤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，天津格蘭富機(jī)械密封件，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，天津格蘭富機(jī)械密封件，對(duì)旋轉(zhuǎn)軸的振擺和軸對(duì)殼體的偏斜不敏感，天津格蘭富機(jī)械密封件。（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。工業(yè)園區(qū)泵用機(jī)械密封件。天津格蘭富機(jī)械密封件</p><div

機(jī)械密封(mechanicalseal)是指由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用下以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置。機(jī)械密封漏液的原因及水泵漏液的解決辦法：不管是自吸泵、離心泵、QW潛水排污泵等機(jī)械密封是工業(yè)水泵漏液的主要原因。機(jī)械密封也稱端面密封,其有一對(duì)垂直于旋轉(zhuǎn)軸線的端面,該端面在流體壓力及補(bǔ)償機(jī)械外彈力的作用下,依賴輔助密封的配合與另一端保持貼合,并相對(duì)滑動(dòng),從而防止流體泄漏。01常見的滲漏現(xiàn)象機(jī)械密封滲漏的比例占全部工業(yè)水泵漏液原因的50%以上,機(jī)械密封的運(yùn)行好壞直接影響到水泵的正常運(yùn)行,現(xiàn)總結(jié)分析如下：02引發(fā)滲透的原因（一）壓力產(chǎn)生的滲漏1.故障一：高壓和壓力波造成的機(jī)械密封滲漏產(chǎn)生原因：彈簧比壓力及總比壓設(shè)計(jì)過(guò)大，當(dāng)密封腔內(nèi)壓力超過(guò)3MPa時(shí),會(huì)使密封端面比壓過(guò)大,液膜難以形成,密封端面磨損嚴(yán)重,發(fā)熱量增多,造成密封面熱變形。解決方法：裝配機(jī)封時(shí),彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過(guò)大或過(guò)小的現(xiàn)象,高壓條件下的機(jī)械密封應(yīng)采取措施。為使端面受力合理，盡量減小變形,可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料,并加強(qiáng)冷卻的潤(rùn)滑措施。</p><p>
