而外裝式機(jī)械密封多屬于外流型機(jī)械密封（如圖4）。由于外流型泄漏方向和離心力方向相同，所以外流型機(jī)械密封泄漏量較大。因此，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。。綏化FMY212釜用機(jī)械密封件安裝三門峽MR-D釜用機(jī)械密封件。</p><div

使泵運(yùn)行更可靠。通過逆向工程國產(chǎn)化，曾用過彈簧串聯(lián)機(jī)械密封和波紋管面對面雙端面機(jī)械密封，但是使用效果都不好。先后曾經(jīng)出現(xiàn)以下問題：（1）密封采用循環(huán)水，潔凈度不夠不管彈簧還是波紋管密封，外側(cè)密封都是軟對硬的端面配對，一旦雜質(zhì)進(jìn)入密封端面，會使摩擦副受損，導(dǎo)致密封失效。另外如果從***道密封泄漏介質(zhì)具有聚合的特性，雜質(zhì)可能會加劇介質(zhì)聚合，聚合物會影響機(jī)封的使用性能。（2）摩擦副散熱效果不好以前波紋管失效密封曾發(fā)現(xiàn)金屬變色問題，這應(yīng)該是溫度過高所致。波紋管機(jī)封安裝的徑向尺寸太小（小腔密封），無法設(shè)計(jì)將緩沖液引向機(jī)封端面的導(dǎo)流及泵送循環(huán)結(jié)構(gòu)，緩沖液起不到帶走摩擦熱、攪拌熱的降溫作用。（3）循環(huán)管路不暢，循環(huán)效果不好彈簧串聯(lián)密封的外側(cè)密封靠泵送環(huán)帶動緩沖液循環(huán)帶走熱量，泵送環(huán)產(chǎn)生的壓頭有限，循環(huán)管路的管徑細(xì)小產(chǎn)生的程阻大，會導(dǎo)致緩沖液循環(huán)不暢，甚至不循環(huán)，起不到給密封循環(huán)降溫的作用。三、優(yōu)化方案1.采用PLAN54密封方案參考早期建設(shè)的同類裝置，P-l18位號泵的軸封密封采用PLAN54輔助沖洗方案，此方案為加壓雙端面密封系統(tǒng)，機(jī)封采用STB35A背靠背接觸式濕式波紋管密封，如圖3所示。</p><p>
