機(jī)械密封原理機(jī)械密封主要是將較易泄漏的軸向密封改為不易泄漏的端面密封。當(dāng)軸轉(zhuǎn)動(dòng)時(shí)，帶動(dòng)了彈簧座、彈簧壓板、動(dòng)環(huán)等零件一起轉(zhuǎn)動(dòng)，由于彈簧力的作用使動(dòng)環(huán)緊緊壓在靜環(huán)上。軸旋轉(zhuǎn)時(shí)，動(dòng)環(huán)與軸一起旋轉(zhuǎn)，而靜環(huán)則固定在座架上靜止不動(dòng)，這樣動(dòng)環(huán)與靜環(huán)相接觸的環(huán)形密封面阻止了介質(zhì)的泄漏。機(jī)械密封結(jié)構(gòu)形式外裝式特點(diǎn)：外裝式機(jī)械密封彈簧不與介質(zhì)接觸,可以用于強(qiáng)腐蝕、高粘度、易結(jié)晶以及含有固體顆粒的介質(zhì)等工況條件。但其動(dòng)環(huán)端面在介質(zhì)壓力的作用下存被打開的趨勢,因此使用壓力比較低,一般應(yīng)不大于1Mpa。內(nèi)裝式機(jī)械密封則可以滿足較高壓力的工況要求。內(nèi)裝式受力情況比較好，剛開車時(shí)介質(zhì)壓力較低，由不太大的彈簧力即可對摩擦面構(gòu)成初始的密封，此時(shí)因端面比壓較小，容易形成液膜。內(nèi)裝式端面比壓隨介質(zhì)壓力增在而增大，因而增加了密封的可靠性。RPHRO150-230B凱士比機(jī)械密封。綿陽OMEGA125-500凱士比機(jī)械密封</p><p

2、設(shè)備的密封部位在安裝時(shí)應(yīng)保持清潔，密封零件應(yīng)進(jìn)行清洗，密封端面完好無損，防止雜質(zhì)和塵帶入密封部位；3、在安裝過程中嚴(yán)禁碰擊、敲打，以免使機(jī)械密封摩擦付破損而密封失效；4、安裝時(shí)在與密封相接觸的表面應(yīng)涂一層清潔的機(jī)械油，以便能順利安裝；5、安裝靜環(huán)壓蓋時(shí)，擰緊螺絲必須受力均勻，保證靜環(huán)端面與軸心線的垂直要求；6、安裝后用手推動(dòng)動(dòng)環(huán)，能使動(dòng)環(huán)在軸上靈活移動(dòng)，并有一定彈性；7、安裝后用手盤動(dòng)轉(zhuǎn)軸、轉(zhuǎn)軸應(yīng)無輕重感覺；8、設(shè)備在運(yùn)轉(zhuǎn)前必須充滿介質(zhì)，以防止干摩擦而使密封失效；9、對易結(jié)晶、顆粒介質(zhì)，對介質(zhì)溫度>80℃時(shí)，應(yīng)采取相應(yīng)的沖洗、過濾、冷卻措施，各種輔助裝置請參照機(jī)械密封有關(guān)標(biāo)準(zhǔn)。10、安裝時(shí)在與密封相接觸的表面應(yīng)涂一層清潔的機(jī)械油，要特別注意機(jī)械油的選擇對于不同的輔助密封材質(zhì)，避免造成O型圈侵油膨脹或加速老化，造成密封提前失效。四、密封介質(zhì)溫度T在沒有外冷條件下,機(jī)械密封的比較高溫度一般取決于輔助密封材料的安全使用溫度.見下表：材料安全使用溫度℃?zhèn)渥⒍【ο鹉z（NBR）-30~100超過安全使用溫度請使用金屬波紋管機(jī)械密封硅橡膠（MVQ）-40~200乙丙橡膠（EPR）-10~160氟橡膠（FPM）-30~180聚四氟乙烯。NLT500-570凱士比機(jī)械密封</p></p><br
