按補(bǔ)償機(jī)構(gòu)彈性元件的運(yùn)動狀況，可分為旋轉(zhuǎn)式和靜止式機(jī)械密封。補(bǔ)償機(jī)構(gòu)隨軸旋轉(zhuǎn)的稱為旋轉(zhuǎn)式機(jī)械密封（圖2）；補(bǔ)償機(jī)構(gòu)不旋轉(zhuǎn)的（安裝在壓蓋內(nèi)）稱為靜止式機(jī)械密封（圖3）。補(bǔ)償機(jī)構(gòu)旋轉(zhuǎn)時易產(chǎn)生質(zhì)量不平衡，同時消耗攪拌功率，因此，旋轉(zhuǎn)式密封不能用于高速；而靜止式密封可用于高速。但是旋轉(zhuǎn)式密封安裝較方便，所以，普通的機(jī)械密封大多采用旋轉(zhuǎn)式結(jié)構(gòu)。按靜環(huán)的安裝位置可分為內(nèi)裝式和外裝式機(jī)械密封。靜環(huán)裝于密封壓蓋（或相當(dāng)于密封壓蓋的零件）內(nèi)側(cè)（即面向主機(jī)工作腔側(cè)）的機(jī)械密封稱為內(nèi)裝式機(jī)械密封（如圖1）；反之，延慶區(qū)205型釜用機(jī)械密封，延慶區(qū)205型釜用機(jī)械密封，在密封壓蓋的外側(cè)安裝靜環(huán)時稱為外裝式機(jī)械密封（圖4）。內(nèi)裝式機(jī)械密封可用于溫度和壓力較高，以及介質(zhì)對動環(huán)及彈性元件的腐蝕性不高的工況。外裝式機(jī)械密封適用于低壓（或負(fù)壓）和介質(zhì)具有腐蝕性的工況。(圖4)密封流體在密封端面間的泄漏方向和離心力方向相反的機(jī)械密封稱為內(nèi)流型機(jī)械密封；密封流體在密封端面間的泄漏方向與離心力方向相同時稱為外流型機(jī)械密封。一般情況下，內(nèi)流型機(jī)械密封多出現(xiàn)在內(nèi)裝式機(jī)械密封中（如圖1、2、3），延慶區(qū)205型釜用機(jī)械密封，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。鶴壁2009釜用機(jī)械密封件。延慶區(qū)205型釜用機(jī)械密封</p><div

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機(jī)械密封傳動座和動環(huán)的傳動方式1）銷釘傳動。通過推環(huán)，在推環(huán)和動環(huán)之間用銷釘實(shí)現(xiàn)傳動（圖35），這種傳動方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動環(huán)外緣制成圓弧槽，而將與此接觸的傳動座壓成突耳，使之嵌入動環(huán)的槽中，實(shí)現(xiàn)傳動（圖13）。這種結(jié)構(gòu)可用于大彈簧，也可用于小彈簧的密封結(jié)構(gòu)。3）并圈彈簧傳動。傳動座與彈簧以及彈簧和動環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實(shí)現(xiàn)傳動（圖34），當(dāng)然也有旋向的要求。這種結(jié)構(gòu)都用在大彈簧的密封結(jié)構(gòu)上。4）勾圈彈簧傳動。為了增加并圈彈簧傳動的可靠性，彈簧的兩個端頭制成彎勾形，分別鉤住傳動座和動環(huán)（圖36）。5）離合器傳動。傳動座和動環(huán)（或通過推環(huán)）分別制成方形的凸起和缺口，組裝好后凸起插入缺口中實(shí)現(xiàn)傳動（圖37）。6）波紋管傳動。這種方式是波紋管型密封的特有結(jié)構(gòu)，波紋管兩端分別與傳動座和動環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對金屬波紋管，則采用焊接；對于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機(jī)械密封的動環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。延慶區(qū)205型釜用機(jī)械密封蕪湖212釜用機(jī)械密封件。</p><div

輔助密封圈是機(jī)械密封上**薄弱環(huán)節(jié)，當(dāng)溫度超過80℃時普通橡膠已不適用，溫度超過230~250℃，聚四氟乙烯也不能使用.此外，由于高溫、易燃介質(zhì)的裂解物沉積會使彈簧阻塞.所以，當(dāng)溫度超過220℃時就應(yīng)采用金屬波紋管型機(jī)械密封，或者采用金屬波紋管與普通機(jī)械密封相結(jié)合的密封結(jié)構(gòu).3.采取冷卻措施在高溫下，為了使密封可靠運(yùn)行，盡可能對機(jī)械密封進(jìn)行冷卻，要避免在干摩擦狀態(tài)下工作.必須保持密封間隙中的溫度在密封液的汽化溫度以下.冷卻措施就是對密封進(jìn)行溫度控制，常用的溫度控制有沖洗、阻封、加強(qiáng)液體循環(huán)等(詳見第七章一節(jié)溫度控制裝置)。在高溫下，還可采用以下措施:(1)用Diphy1(二苯及二苯氧化物的混合物)作為阻封液，它是冷態(tài)無壓的換熱劑(阻封液由泵效螺旋輸送);(2)在超高溫下或者沒有適當(dāng)?shù)囊后w時，也可通人氮?dú)?、氬氣，以防止空氣引起的氧?4.鑲嵌摩擦副問題密封環(huán)鑲嵌是充分利用端面材料和基體材料的特性，提高材料使用價(jià)值，一般對高溫密封采用熱鑲法.但是，由于端面耐磨材料和基體材料的熱脹系數(shù)有差異，在高溫下使用時會產(chǎn)生摩擦環(huán)松動、脫落。因此，對鑲嵌結(jié)構(gòu)的摩擦環(huán)采用的溫度應(yīng)予以特別注意.熱鑲結(jié)構(gòu)產(chǎn)生松動、脫落的原因，除了與使用溫度有關(guān)外。</p><p> 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，也就是由介質(zhì)壓力變化引起的端面比壓的增量小于介質(zhì)壓力的增量，稱為平衡型密封。根據(jù)密封端面的數(shù)量和布置方式可分為單端面、雙端面及多端面機(jī)械密封。兩組密封端面“背靠背”（圖10a）或“面對面”（圖10b）布置的密封叫雙端面機(jī)械密封。對于工作介質(zhì)有毒、易爆、易燃、易揮發(fā)、易結(jié)晶、高溫、低溫或工作介質(zhì)是氣體，或?qū)τ诟哒婵斩鹊拿芊?，可用雙端面密封。此時雙端面之間的密封腔引入封液進(jìn)行堵封、潤滑和冷卻。一般情況下封液選用潔凈和潤滑性好的介質(zhì)。二、串聯(lián)機(jī)械密封應(yīng)用的工況兩組或兩組以上同向布置的單端面機(jī)械密封組成串聯(lián)機(jī)械密封（圖11）。這種密封方式使密封腔的壓力逐級降低，介質(zhì)不至外漏。串聯(lián)密封一般情況下很少采用，只有在壓力很高時采用。補(bǔ)償機(jī)構(gòu)為波紋管，密封環(huán)（動環(huán)或靜環(huán)）和波紋管制成一個整體，中間沒有輔助密封圈（見圖8）稱為波紋音式機(jī)械密封。波紋音式機(jī)械密封減少了一個泄漏點(diǎn)；同時減少了補(bǔ)償機(jī)構(gòu)的摩擦阻力，改善了追隨性；對于焊接金屬波紋管密封（圖8b）使用溫度不受輔助密封圈的限制；對于四氟波紋管密封（圖8a）可用于腐蝕性介質(zhì)中。蕪湖M461釜用機(jī)械密封件。</p><div
