摩擦副故障是機(jī)械密封失效的主要因素，國(guó)內(nèi)齊魯石油化工公司煉油廠對(duì)國(guó)產(chǎn)104型和110型機(jī)械密封在274臺(tái)泵上應(yīng)用一個(gè)周期(10個(gè)月)后機(jī)械密封失效率和失效原因統(tǒng)計(jì)分析結(jié)果如表9-5、9-6、9-7所示.從表9-5、9-6、9-7分析可見:1.熱油和低粘度油失效率兩者合計(jì)為，說明熱油和低粘度介質(zhì)的密封仍然是煉油廠目前研究的主課題。此外，高粘度介質(zhì)對(duì)密封也不利.2.機(jī)械密封失效部位以摩擦副居多，占62%.失效現(xiàn)象表現(xiàn)在摩擦副磨損和碳化鎢環(huán)與動(dòng)環(huán)座發(fā)生相對(duì)轉(zhuǎn)動(dòng)，兩者占總失效次數(shù)的，這個(gè)現(xiàn)象與國(guó)外有人對(duì)五年間300套機(jī)械密封的故障統(tǒng)計(jì)數(shù)據(jù)很接近.3.失效原因不僅與機(jī)械密封本身有關(guān)，還與工作條件和輔助裝置有關(guān)，無沖洗措施是機(jī)械密封失效的主要原因之一二、機(jī)械密封的故陣處理機(jī)械密封的故障現(xiàn)象很多，但主要反映在在泄漏上，泄漏現(xiàn)象又可分為:1.開始運(yùn)轉(zhuǎn)階段的泄漏;2.周期性泄漏;3.經(jīng)常泄漏;4.突然和大量泄漏.伴隨泄漏，還會(huì)出現(xiàn)密封發(fā)熱、冒煙、振動(dòng)、響聲.、功率增大等現(xiàn)象.由于造成泄漏的因素很多，。</p><p> 機(jī)泵機(jī)械密封是動(dòng)力機(jī)械和流體機(jī)械裝置中不可缺少的零件，對(duì)機(jī)械的安全性要有重要意義。機(jī)泵機(jī)械密封泄漏的原因多種多樣，比如密封沖洗水的問題、裝置本身存在的缺陷、填充介質(zhì)對(duì)裝置的腐蝕性、密封性能不足等，針對(duì)這些問題必須從根源入手，依次解決工藝、設(shè)備、檢修、操作上的問題，只有做到排除故障才能徹底解決機(jī)械的密封問題，保證機(jī)泵機(jī)械的良好運(yùn)轉(zhuǎn)。實(shí)際生產(chǎn)中，不同的操作條件和生產(chǎn)條件會(huì)對(duì)機(jī)泵機(jī)械密封產(chǎn)生重要的影響，甚至可能導(dǎo)致機(jī)泵機(jī)械失去基本性能，因此對(duì)機(jī)泵機(jī)械密封泄漏原因的分析具有重要的實(shí)際生產(chǎn)意義和安全意義，原因分析能提高安全性、機(jī)械的稼動(dòng)率。機(jī)械的壽命等，因此機(jī)械密封的選擇為維護(hù)歷來是眾多企業(yè)的重中之重。機(jī)泵機(jī)械密封失效的原因腐蝕引起機(jī)械密封的失效機(jī)泵機(jī)械密封的腐蝕包括金屬環(huán)腐蝕、非金屬環(huán)腐蝕以及輔助密封圈及接觸部位的腐蝕。1金屬環(huán)腐蝕金屬環(huán)本身不具備抗腐蝕能力，直接接觸到腐蝕性介質(zhì)表面會(huì)被腐蝕，初期階段會(huì)出現(xiàn)怪聲、泄露、磨損等現(xiàn)象。腐蝕會(huì)以一定的速度往內(nèi)部蔓延。在外力的作用下金屬環(huán)會(huì)發(fā)生應(yīng)力變形，變形后外露的部分是腐蝕的重災(zāi)區(qū)，并通過薄弱環(huán)節(jié)逐漸影響到其他區(qū)域，進(jìn)而產(chǎn)生機(jī)械密封泄漏。銅陵橡膠波紋管機(jī)械密封件。</p><div

一、機(jī)械密封概述機(jī)械密封（端面密封）是一種用來解決旋轉(zhuǎn)軸與機(jī)體之間密封的裝置。它是由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面的流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用及輔助密封的配合下保持貼合下并相對(duì)滑動(dòng)而構(gòu)成防止流體泄漏的裝置，常用于泵、壓縮機(jī)、反應(yīng)攪拌釜等旋轉(zhuǎn)式流體機(jī)械，也用于齒輪箱、船舶尾軸等密封。因此，機(jī)械密封是一種通用的軸封裝置。機(jī)械密封結(jié)構(gòu)多種多樣，常用的機(jī)械密封結(jié)構(gòu)是端面密封。端面密封的靜環(huán)、動(dòng)環(huán)組成一對(duì)摩擦副，摩擦副的作用是防止介質(zhì)泄漏。它要求靜環(huán)、動(dòng)環(huán)，具有良好的耐磨性，動(dòng)環(huán)可以在軸向靈活的移動(dòng)，自動(dòng)補(bǔ)償密封面磨損，使之與靜環(huán)良好的貼合；靜環(huán)具有浮動(dòng)性，起緩沖作用。為此，密封面要求有良好的加工質(zhì)量，保證密封副有良好的貼合性能。構(gòu)成機(jī)械密封的基本元件有靜環(huán)、動(dòng)環(huán)、壓蓋、推環(huán)、彈簧、定位環(huán)、軸套、動(dòng)環(huán)密封圈、靜環(huán)密封圈軸套密封圈等。彈性元件（彈簧、波紋管）它主要起預(yù)緊、補(bǔ)償和緩沖的作用，要求始終保持足夠的彈性來克服輔助密封和傳動(dòng)件的摩擦和動(dòng)環(huán)等的慣性，保證端面密封副良好的貼合和動(dòng)環(huán)的追隨性，材料要求耐腐蝕、耐疲勞。輔助密封。江陰水泵機(jī)械密封件。淮北機(jī)械密封大全</p><p
