***節(jié)機(jī)械密封原理機(jī)械密封是一種旋轉(zhuǎn)機(jī)械的軸封裝置。比如離心泵、離心機(jī)、反應(yīng)釜和壓縮機(jī)等設(shè)備。由于傳動(dòng)軸貫穿在設(shè)備內(nèi)外，這樣，軸與設(shè)備之間存在一個(gè)圓周間隙，設(shè)備中的介質(zhì)通過該間隙向外泄漏，如果設(shè)備內(nèi)壓力低于大氣壓，則空氣向設(shè)備內(nèi)泄漏，因此必須有一個(gè)阻止泄漏的軸封裝置。軸封的種類很多，由于機(jī)械密封具有泄漏量少和壽命長(zhǎng)等優(yōu)點(diǎn)，所以當(dāng)今世界上機(jī)械密封是這些設(shè)備主要的軸密封方式。機(jī)械密封又叫端面密封，在國(guó)家有關(guān)標(biāo)準(zhǔn)中是這樣定義的：“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)彈力（或磁力）的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?！币?、機(jī)械密封的分類機(jī)械密封近年來發(fā)展很快，根據(jù)不同的工況出現(xiàn)了各種各樣的結(jié)構(gòu)，但無(wú)論哪種結(jié)構(gòu)都由以下四部分組成：一部分是由動(dòng)環(huán)和靜環(huán)組成的密封端面，有時(shí)也稱為摩擦副。第二部分是由彈性元件為主要零件組成的緩沖補(bǔ)償機(jī)構(gòu)，其作用是使密封端面緊密貼合。第三部分是輔助密封圈，其中有動(dòng)環(huán)和靜環(huán)密封圈。第四部分是使動(dòng)環(huán)隨軸旋轉(zhuǎn)的傳動(dòng)機(jī)構(gòu)。機(jī)械密封實(shí)現(xiàn)的原理如圖所示：軸通過傳動(dòng)座（6）和推環(huán)（4），帶動(dòng)動(dòng)環(huán)（2）旋轉(zhuǎn)，靜環(huán)(1)固定不動(dòng)。</p><p> 或殼體）的配合公差；?防轉(zhuǎn)銷與孔的配合公差。釜用機(jī)械密封零件公差與配合基本與上述相同。根據(jù)反應(yīng)釜攪拌軸的偏擺和振動(dòng)較大的特點(diǎn)，動(dòng)環(huán)內(nèi)徑尺寸一般比軸徑大1mm，其尺寸為d+1，同樣，靜環(huán)內(nèi)徑尺寸相應(yīng)應(yīng)比軸徑加大2~4mm，其尺寸為d+（2~4）。表9-1、表9-2列出機(jī)械密封常用尺寸公差數(shù)值。二、機(jī)械密封主要零件的技術(shù)要求1動(dòng)、靜環(huán)的形位公差與表面光潔度圖9-2為幾種典型的機(jī)械密封動(dòng)、靜環(huán)零件圖，圖中表示了關(guān)鍵部位的形位公差與表面光潔度。密封端面是機(jī)械密封的**關(guān)鍵部位，其平面度要求≤，其表面粗糙度對(duì)于硬質(zhì)材料一般要求為Ra≤，軟質(zhì)材料為Ra≤。其中平面度及垂直度公差見表9-3。2彈簧的技術(shù)要求機(jī)械密封一般情況下采用圓柱螺旋壓縮彈簧，根據(jù)機(jī)械密封使用特點(diǎn)，壓縮彈簧的主要技術(shù)要求為：彈簧產(chǎn)品圖樣應(yīng)包括線徑、中徑（外徑）、自由高度、工作高度、工作負(fù)荷、彈簧剛度、有效圈數(shù)、總?cè)?shù)、材料等主要技術(shù)參數(shù)。彈簧在工作高度（推薦選用自由高度的67%±5%為工作高度）的負(fù)荷數(shù)值一般應(yīng)在試驗(yàn)負(fù)荷的62%~72%之間。注：測(cè)定彈簧特性時(shí)，以彈簧壓并高度時(shí)負(fù)荷數(shù)值作為試驗(yàn)負(fù)荷數(shù)值。彈簧在工作高度時(shí)的工作負(fù)荷F的極限偏差按表9-4的規(guī)定。彈簧外徑D2。三明襄樊五二五泵用機(jī)械密封件選型。</p><div

彈性力完全由波紋管產(chǎn)生，因此波紋管設(shè)計(jì)時(shí)要考慮其彈率。一般將波紋管的彈率設(shè)計(jì)得小些，當(dāng)要求一定的彈力時(shí)，波紋管的壓縮量就要適當(dāng)?shù)丶哟蟆＿\(yùn)轉(zhuǎn)相當(dāng)長(zhǎng)時(shí)間后，如果密封端面磨損，波紋管自動(dòng)補(bǔ)償，而彈力降低不會(huì)大，始終保持密封端面有足夠的壓比。為保證足夠的彈性力，壓縮量在10mm左右，不能低于6mm。工作時(shí)每個(gè)波的變形以小為宜，為保證一定的壓縮量，要適當(dāng)增加波數(shù)，保持波距。一般波數(shù)取16～20，溫度和壓力高時(shí)波數(shù)宜取多。波紋管的彈率是幾何形狀和材料的函數(shù)，常用下式計(jì)算：k=πEt3(c)d2/2nB3d1式中k——波紋管彈率，N／mm；E——材料在工作溫度下的彈性模量，N/mm2；t——波片厚度，mmn——波紋管波數(shù)；d1、d2——分別為波紋管的內(nèi)外徑，mm；B——波紋管的片寬，mm。B=（d2-d1）／2公式中沒有考慮波片的斷面形狀等因素，因此有一定的誤差。實(shí)際工作中可在彈簧測(cè)力計(jì)上測(cè)量其彈率。普通彈簧的彈率計(jì)算在一般“機(jī)械零件”書上能找到，故在此不作介紹。非對(duì)稱型波紋管焊接金屬波紋管機(jī)械密封以其結(jié)構(gòu)簡(jiǎn)單、伸縮性好和耐高溫等優(yōu)點(diǎn)，得到了日益廣的應(yīng)用，尤其是高溫泵的密封中，在有的國(guó)家已成為主要的軸封方式。國(guó)內(nèi)的焊接金屬波紋管密封質(zhì)量不夠穩(wěn)定。銅川襄樊五二五泵用機(jī)械密封件廠家。鎮(zhèn)江螺桿泵用機(jī)械密封件</p><p

稱為環(huán)座）則用普通材料制成。為解決硬質(zhì)合金環(huán)和環(huán)座之間的聯(lián)接和密封，產(chǎn)生了熱裝式、帶密封圈式、焊接和釬焊四種組合式密封環(huán)。帶O型圈的組合式由匐環(huán)結(jié)構(gòu)封環(huán)在硬質(zhì)合金環(huán)與環(huán)座之間用H7／g8的滑動(dòng)配合。在兩者配合圓柱面間置一聚四氟乙烯或合成橡膠制成的O形密封圈，防止其間的密封流體泄漏，且將硬質(zhì)合金環(huán)與環(huán)座組合在一起。在硬質(zhì)合金環(huán)與環(huán)座的平面結(jié)合處設(shè)一銷釘，以傳遞扭矩。此種組合結(jié)構(gòu)，無(wú)組合應(yīng)力產(chǎn)生／也無(wú)由此引起的組合密封環(huán)的密封端面的變形，但是組合密封環(huán)零件的數(shù)量增加了，還需要在硬質(zhì)合金環(huán)上鉆孔或槽，給制造增加了難度，同時(shí)由于增設(shè)了o形圈，密封環(huán)的使用溫度受到了限制。熱裝式密封環(huán)的結(jié)構(gòu)為提高帶O形圈密封環(huán)的使用溫度，出現(xiàn)了熱裝式密封環(huán)。它是靠硬質(zhì)合金環(huán)和環(huán)座之間的過盈配合來傳遞扭矩并實(shí)現(xiàn)密封，是目前應(yīng)用**多的一種密封環(huán)（圖23）。這種密封環(huán)組合時(shí)將環(huán)座加熱，環(huán)座孔受熱脹大，放入硬質(zhì)合金環(huán)，冷卻之后兩者在過盈下完成組合，再在常溫下研磨和拋光密封端面到要求的精度。這種環(huán)的缺點(diǎn)是，隨著時(shí)間的推移，環(huán)境和使用溫度的變化，密封端面的平面度將發(fā)生變化而不符合要求。究其原因，一是熱裝結(jié)構(gòu)本身存在過盈。鎮(zhèn)江螺桿泵用機(jī)械密封件</p></p><br
