二、機(jī)械密封原理機(jī)械密封是一種依靠彈性元件對(duì)動(dòng)、靜環(huán)端面密封副的預(yù)緊和介質(zhì)壓力與彈性元件壓力的壓緊而達(dá)到密封的軸向端面密封裝置。機(jī)械密封通常由靜環(huán)、動(dòng)環(huán)、壓緊元件和密封元件組成。動(dòng)環(huán)和靜環(huán)的端面組成一對(duì)摩擦副，動(dòng)環(huán)靠密封室中液體的壓力使其端面壓緊在靜環(huán)端面上，并在兩環(huán)端面上產(chǎn)生適當(dāng)?shù)谋葔汉捅３忠粚訕O薄的液體膜而達(dá)到密封的目的。壓緊元件產(chǎn)生壓力，可使泵在不運(yùn)轉(zhuǎn)狀態(tài)下，也保持端面貼合，保證密封介質(zhì)不外漏，并防止雜質(zhì)進(jìn)入密封端面。密封圈起密封動(dòng)環(huán)與軸的間隙、靜環(huán)與壓蓋的間隙的作用，同時(shí)對(duì)泵的振動(dòng)、沖擊起緩沖作用，江蘇泵用機(jī)械密封圖片大全。機(jī)械密封在實(shí)際運(yùn)行中不是一個(gè)孤立的部件，它是與泵的其它零部件一起組合起來(lái)運(yùn)行的。三、機(jī)械密封的輔助設(shè)施—沖洗裝置沖洗裝置是機(jī)械密封主要的輔助設(shè)施，泵在運(yùn)轉(zhuǎn)過(guò)程中，密封腔中沉積或形成雜質(zhì)，必須進(jìn)行沖洗。否則會(huì)因結(jié)晶的析出、顆粒雜質(zhì)的沉淀，江蘇泵用機(jī)械密封圖片大全，使機(jī)械密封動(dòng)、靜環(huán)失去浮動(dòng)性，彈簧失靈。更嚴(yán)重的是顆粒磨損、雜質(zhì)進(jìn)入摩擦副會(huì)加劇磨損，江蘇泵用機(jī)械密封圖片大全，導(dǎo)致機(jī)械密封迅速失效。所以，一般情況下泵用機(jī)械密封均應(yīng)進(jìn)行沖洗。關(guān)于機(jī)械密封的沖洗方案（如下圖展示），有非常多種，適用于不同的工作場(chǎng)合，小編將在下期中。內(nèi)蒙古襄樊五二五泵用機(jī)械密封型號(hào)。江蘇泵用機(jī)械密封圖片大全</p><div

機(jī)泵裝置中，機(jī)動(dòng)設(shè)備的機(jī)械密封約占整個(gè)動(dòng)密封數(shù)量的80%-85%。而在機(jī)泵故障中，機(jī)械密封的故障大約占整個(gè)維修工作量的一半。可見(jiàn)機(jī)械密封在機(jī)泵維修中所占的位置。由于機(jī)泵所輸送的介質(zhì)千差萬(wàn)別，工藝條件各不相同，所以了解這些情況對(duì)機(jī)封的選擇及維護(hù)很重要。結(jié)合多年來(lái)在機(jī)封選擇和維修中的經(jīng)驗(yàn)，介紹幾種特殊工況下機(jī)械密封的工作特點(diǎn)和注意事項(xiàng)。一、高溫下的機(jī)械密封一般情況下，介質(zhì)的溫度超過(guò)120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問(wèn)題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長(zhǎng)時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會(huì)加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。為保證機(jī)械密封在高溫環(huán)境下正常工作，可以采取如下措施。1．給機(jī)封增加冷卻沖洗裝置。2．選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外。江蘇泵用機(jī)械密封圖片大全北京襄樊五二五泵用機(jī)械密封型號(hào)。</p><div

石油化工流程泵大都選用內(nèi)流型機(jī)械密封，只有在壓力和溫度不高的腐蝕性介質(zhì)中才選用外流型機(jī)械密封。按補(bǔ)償機(jī)構(gòu)中彈簧的數(shù)量可分為多彈簧和單彈簧機(jī)械密封。補(bǔ)償機(jī)構(gòu)中有多個(gè)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(gè)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(jiǎn)單。有的密封型式還用彈簧傳遞扭矩。國(guó)產(chǎn)密封應(yīng)用大彈簧較多，但不能用于高速。圖5多彈簧機(jī)械密封圖6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(shí)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8）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）。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。</p><p>
