機(jī)械密封的工作原理機(jī)械密封又稱端面密封，是一種旋轉(zhuǎn)機(jī)械的軸封裝置。由于傳動(dòng)軸與設(shè)備之間有一圈間隙，當(dāng)設(shè)備內(nèi)介質(zhì)壓力與外界大氣壓力有差量時(shí)，會(huì)出現(xiàn)介質(zhì)外泄或空氣滲入。軸封的作用就在于消除此現(xiàn)象，以保證設(shè)備正常工作。機(jī)械密封作為軸封的一種，因其泄露量小、使用壽命長(zhǎng)、無(wú)須經(jīng)常維修等優(yōu)點(diǎn)故被普遍采用，新余HPKY80-400凱士比機(jī)械密封，新余HPKY80-400凱士比機(jī)械密封。機(jī)械密封是靠一對(duì)或幾對(duì)垂直于軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)的彈力作用下保持接合并相對(duì)滑動(dòng)配以輔助密封而達(dá)到的阻漏的軸封裝置。機(jī)械密封與軟填料密封對(duì)比優(yōu)點(diǎn)：（1）密封性能高，泄露量很小，新余HPKY80-400凱士比機(jī)械密封，對(duì)于長(zhǎng)期運(yùn)轉(zhuǎn)的設(shè)備也能保證良好的密封效果。（2）使用壽命長(zhǎng)，在化工介質(zhì)中一般能工作半年以上。（3）摩擦功率消耗小，減小了軸功率的損耗，其摩擦功率約為軟填料密封的10%～50%。（4）維修周期長(zhǎng)，補(bǔ)償裝置可再端面磨損后做微量的壓緊，一般情況下不需經(jīng)常維修。（5）抗振性能好，對(duì)轉(zhuǎn)動(dòng)軸的振動(dòng)以及軸的偏斜不敏感。（6）適用范圍廣，機(jī)械密封能用于高溫、低溫、高壓、真空工況，以及各種腐蝕介質(zhì)和含磨粒介質(zhì)。缺點(diǎn)：（1）結(jié)構(gòu)較復(fù)雜，對(duì)加工精度和質(zhì)量要求較高。（2）因其復(fù)雜結(jié)構(gòu)安裝、拆卸不便。（3）一次維修和保養(yǎng)成本較高。（4）單件價(jià)格較高。凱士比機(jī)械密封NLT300-400。新余HPKY80-400凱士比機(jī)械密封</p><div

四、故障原因機(jī)械密封的故障大體上都是由異常的泄漏、異常的磨損、異常的扭矩等現(xiàn)象出現(xiàn)后才被人們所知道。造成故障的原因大致有如下四方面：1、機(jī)械密封的設(shè)計(jì)選型不對(duì)；2、機(jī)械密封質(zhì)量不好；3、使用或安裝機(jī)械密封的機(jī)器本身精度達(dá)不到要求；4、機(jī)器運(yùn)行操作錯(cuò)誤。具體情況具體分析五、密封失效的原因及分析（一）密封失效主要有下述三種原因：1、密封面打開(kāi)在修理機(jī)械密封時(shí)，85％的密封失效不是因磨損造成，而是在磨損前就已泄漏了。當(dāng)密封面一打開(kāi)，介質(zhì)中的固體微粒在液體壓力的作用下進(jìn)入密封面，密封面閉合后，這些固體微粒就嵌入軟環(huán)（通常是右墨環(huán)）的面上，這實(shí)際成了一個(gè)“砂輪”會(huì)損壞硬環(huán)表面。由于動(dòng)環(huán)或橡膠圈緊固在軸（軸套）上，當(dāng)軸串動(dòng)時(shí)，動(dòng)環(huán)不能及時(shí)貼合，而使密封面打開(kāi)，并且密封面的滯后閉合，就使固體微粒進(jìn)入密封面中。同時(shí)軸（軸套）和滑動(dòng)部件之間也存在有固體微粒，影響橡膠圈或動(dòng)環(huán)的滑動(dòng)（相對(duì)動(dòng)密封點(diǎn)，常見(jiàn)故障）。另外，介質(zhì)也會(huì)在橡膠圈與軸（軸套）磨擦部位產(chǎn)生結(jié)晶物，在彈簧處也會(huì)存有固體物質(zhì)，都會(huì)使密封面打開(kāi)。2過(guò)熱因密封面上會(huì)產(chǎn)生熱，故橡膠圈使用溫度應(yīng)低于設(shè)計(jì)規(guī)范。氟橡膠和聚四氟乙烯的使用溫度為216℃。新余HPKY80-400凱士比機(jī)械密封黑龍江凱士比機(jī)械密封廠。</p><div

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(wú)損，防止雜質(zhì)和塵帶入密封部位；3、在安裝過(guò)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(pán)動(dòng)轉(zhuǎn)軸、轉(zhuǎn)軸應(yīng)無(wú)輕重感覺(jué)；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(duì)易結(jié)晶、顆粒介質(zhì)，對(duì)介質(zhì)溫度>80℃時(shí)，應(yīng)采取相應(yīng)的沖洗、過(guò)濾、冷卻措施，各種輔助裝置請(qǐng)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(duì)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(méi)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(jiàn)下表：材料安全使用溫度℃?zhèn)渥⒍【ο鹉z（NBR）-30~100超過(guò)安全使用溫度請(qǐng)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。</p><p> 動(dòng)力密封化工泵在與運(yùn)轉(zhuǎn)時(shí)，副葉輪所產(chǎn)生的壓頭平衡了主葉輪出口高壓液體，從而實(shí)現(xiàn)密封。停車(chē)時(shí)，副葉輪不起作用，因此必須同時(shí)配備停車(chē)密封裝置解決停車(chē)時(shí)可能產(chǎn)生的化工泵泄漏。副葉輪密封結(jié)構(gòu)簡(jiǎn)單、密封可靠、使用壽命長(zhǎng)，化工泵運(yùn)轉(zhuǎn)中可實(shí)現(xiàn)滴水不漏，因此在化工泵輸送含雜質(zhì)介質(zhì)的泵上經(jīng)常采用。填料密封軟填料密封盤(pán)根通常由較柔軟的線狀物編織而成，通過(guò)截面積是正方形的條狀物填充在密封腔體內(nèi)，靠壓蓋產(chǎn)生壓緊力，壓緊填料，迫使填料壓緊在密封表面(軸的外表面和密封腔)上，產(chǎn)生密封效果的徑向力，因而起密封作用。硬填料密封硬填料密封有開(kāi)口環(huán)和分瓣環(huán)兩類。機(jī)械密封機(jī)封總是由旋轉(zhuǎn)部件（黃色部分）和靜止部件（橙色部分）兩大部分組成，兩相對(duì)運(yùn)動(dòng)的動(dòng)，靜環(huán)面成為密封的主密封面。機(jī)械密封亦稱端面密封，按國(guó)家有關(guān)標(biāo)準(zhǔn)定義為：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)的彈力（或磁力）作用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。螺旋密封螺旋密封也是動(dòng)力密封的一種形式，它是在旋轉(zhuǎn)的軸上或者在軸的包容套上加工出螺旋槽，軸和套之間充有密封介質(zhì)。軸的旋轉(zhuǎn)使螺旋槽產(chǎn)生類似于泵的輸送作用。凱士比機(jī)械密封ETB050032-160。</p><div

中間沒(méi)有輔助密封圈，因此減少了一個(gè)泄漏點(diǎn);同時(shí)減少了補(bǔ)償機(jī)構(gòu)的摩擦阻力，改善了追隨性;對(duì)于焊接金屬波紋管密封使用溫度不受輔助密封圈的限制。波紋管具有一定的彈性且移動(dòng)沒(méi)有阻力，使用扭矩的傳遞不影響波紋管，能起到補(bǔ)償作用，適用于高溫、高速、高粘度、高腐蝕等各類的工況。故金屬波紋管機(jī)械密封在煉**業(yè)的離心泵上得到***的應(yīng)用。金屬波紋管機(jī)械密封實(shí)物圖金屬波紋管機(jī)械密封優(yōu)點(diǎn)：具有高精密性：焊接波紋管起到彈簧的作用，而且是好多個(gè)彈簧的組合體，所以解決了普通彈簧因離心力變形的問(wèn)題，適應(yīng)高度旋轉(zhuǎn)，并且使密封面受壓均勻，利于防止泄露。具有耐振動(dòng)與***的柔韌性：波紋管柔韌性高，對(duì)振動(dòng)的吸收效果非常好，所以對(duì)徑向跳動(dòng)、軸向間隙、振動(dòng)和擺動(dòng)的適應(yīng)能力非常強(qiáng)，能有效阻止泄露。結(jié)構(gòu)簡(jiǎn)單：不像其他普通機(jī)械密封要由很多零件組成，具有整合組裝、構(gòu)造簡(jiǎn)單、容易裝配的特點(diǎn)能適應(yīng)多種溫度條件的工況：焊接波紋管的熱膨脹系數(shù)小，可在低溫或高溫的下使用，而且沒(méi)有O型圈，擺脫溫度的限制條件，設(shè)計(jì)比較自由。適用于高壓工況：由于波紋管本身能起平衡作用，可設(shè)計(jì)相應(yīng)的密封面積抵消流體壓力，減少密封面的摩擦，從而減少發(fā)熱以及磨損量。新余HPKY80-400凱士比機(jī)械密封</p></p><br
