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，會出現(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、無須經(jīng)常維修等優(yōu)點故被普遍采用。機(jī)械密封是靠一對或幾對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滑動配以輔助密封而達(dá)到的阻漏的軸封裝置。機(jī)械密封與軟填料密封對比優(yōu)點：（1）密封性能高，泄露量很小，對于長期運轉(zhuǎn)的設(shè)備也能保證良好的密封效果。（2）使用壽命長，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，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，對轉(zhuǎn)動軸的振動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，新余MTCA100/3凱士比機(jī)械密封，以及各種腐蝕介質(zhì)和含磨粒介質(zhì)。缺點：（1）結(jié)構(gòu)較復(fù)雜，對加工精度和質(zhì)量要求較高，新余MTCA100/3凱士比機(jī)械密封。（2）因其復(fù)雜結(jié)構(gòu)安裝，新余MTCA100/3凱士比機(jī)械密封、拆卸不便。（3）一次維修和保養(yǎng)成本較高。（4）單件價格較高。凱士比機(jī)械密封ETB080065-200。新余MTCA100/3凱士比機(jī)械密封</p><div

補(bǔ)償機(jī)構(gòu)中有多個彈簧的密封稱為多彈簧機(jī)械密封（圖5）；補(bǔ)償機(jī)構(gòu)中只有一個彈簧的機(jī)械密封稱為單彈簧機(jī)械密封（圖6），多彈簧機(jī)械密封又稱小彈簧機(jī)械密封，這種結(jié)構(gòu)軸向尺寸較小，可用改變彈簧數(shù)量的方法改變彈性力，軸向力較均勻，適用于高速機(jī)械密封，在腐蝕性介質(zhì)中不宜采用。單彈簧機(jī)械密封又稱大彈簧機(jī)械密封，密封結(jié)構(gòu)較為簡單。有的密封型式還用彈簧傳遞扭矩。國產(chǎn)密封應(yīng)用大彈簧較多，但不能用于高速。圖五：多彈簧機(jī)械密封圖六：單彈簧機(jī)械密封補(bǔ)償機(jī)構(gòu)的作用是使密封端面緊密貼合，為達(dá)到此目的，采用的方法有兩種，一是彈性力，二是磁力。只有在系統(tǒng)內(nèi)壓力較低時采用磁力機(jī)械密封（圖7），大多數(shù)都用前者。除了用彈簧形成彈性力外還有用波紋管的，稱為波紋管式機(jī)械密封。波紋管的材料可用橡膠、聚四氟乙烯和焊接的金屬薄片（圖8）等。圖七：磁力機(jī)械密封圖八：波紋管式機(jī)械密封根據(jù)密封面上介質(zhì)載荷的作用情況可分為平衡型和非平衡型密封（圖9）。圖九：平衡型和非平衡型密封非平衡型：載荷系數(shù)k≥1的密封稱為非平衡型密封，換言之，由介質(zhì)壓力變化引起端面比壓的增量大于或等于介質(zhì)壓力的增量。平衡型：載荷系數(shù)K<1的密封。凱士比機(jī)械密封SAF1-147-ES1。</p><div

用以補(bǔ)償軸的振動與偏斜，但間隙不能太大，否則會使動環(huán)密封圈卡入而造成機(jī)械密封機(jī)能的破壞。3、機(jī)械密封緊力的校核。我們通常講的機(jī)械密封緊力也就是端面比壓，端面比壓要合適，過大，將使機(jī)械密封摩擦面發(fā)熱，加速端面磨損，增加摩擦功率；過小，容易漏泄。端面比壓是在機(jī)械密封設(shè)計時確定的，我們在組裝時只能靠測量機(jī)械密封緊力來確定。通常情況的測量方法使測量安裝好的靜環(huán)端面至壓蓋端面的垂直距離，在測量動環(huán)端面至壓蓋端面的垂直距離，兩者的差極為機(jī)械密封的緊力。4、測量補(bǔ)償彈簧的長度是否發(fā)生變化。彈簧性能的發(fā)生變化將會直接影響機(jī)械密封端面比壓。一般情況下彈簧在長時間運行后長度會縮短，補(bǔ)償彈簧在動環(huán)上的機(jī)械密封還會因為離心力的原因而變形。5、測量靜環(huán)防轉(zhuǎn)銷子的長度及銷孔深度，防止銷子過長靜環(huán)不能組裝到位。這種情況出現(xiàn)會損壞機(jī)械密封。三．機(jī)械密封的組裝經(jīng)過清掃檢查、技術(shù)尺寸校核后的機(jī)械密封即可回裝，在這個過程中要注意以下幾點：1、組裝時所有密封圈因該涂以肥皂水等潤滑劑，這樣可以避免組裝過程中損壞膠圈。動靜環(huán)的密封面之間涂以潤滑脂，防止動靜環(huán)密封面在水泵開車前磨損。2、浮動環(huán)組裝時，一定要小心不要碰倒浮動環(huán)彈簧。昌平區(qū)凱士比機(jī)械密封。新余MTCA100/3凱士比機(jī)械密封</p><p
