其缺點是有的波紋管彈力較小，需加輔助彈簧，如（圖8a）所示。集裝式機械密封是將普通的機械密封、軸套和密封壓蓋預(yù)先組合成一個整體，將其安裝到泵上后，不做任何調(diào)整（包括彈簧的壓縮量），只固定軸套和壓蓋，再把剖分式卡環(huán)取下（圖12中的A）即可投入使用。由此可見，卡環(huán)的（軸向）寬度等于彈簧的壓縮量，并且，從外部就可以知道該值的大小和變化情況。事先組裝，容易保證密封的安裝質(zhì)量，可減少因安裝不良引起的失效。近年來集裝式密封發(fā)展很快，因卡環(huán)的結(jié)構(gòu)、軸套與軸的傳動以及軸與軸套之間的密封等方面的不同，出現(xiàn)了許多種集裝式密封。三、國產(chǎn)104型機械密封國產(chǎn)104型機械密封為內(nèi)裝、內(nèi)流、單端面、單彈簧、非平衡型密封，輔助密封圈有V形和O形兩種型式（圖13）。3104型機械密封中的字母“B”表示平衡型密封，其余結(jié)構(gòu)和104型完全相同。B104型密封相當于舊標準（JB1472－75）的110型(GY型)。兩種密封型式工作條件基本相同，*壓力不同。密封腔內(nèi)的溫度一20～80℃，轉(zhuǎn)速不大于3000r／min，介質(zhì)為清水、油類及其它弱腐蝕性液體。104型密封腔中的壓力為0～0．8MPa，而B104型適用壓力為0．6～3．0MPa。經(jīng)過二十多年的實踐，證明這兩種密封結(jié)構(gòu)簡單，使用可靠。因此。三門峽M481釜用機械密封件鎮(zhèn)江M461釜用機械密封件。</p><div

在國產(chǎn)離心泵上得到了***的應(yīng)用。本教材以這兩種國產(chǎn)機械密封為主，結(jié)合其它結(jié)構(gòu)型式（包括進口的密封），就有關(guān)的技術(shù)問題和故障分析。第二節(jié)機械密封的基本元件密封環(huán)是動環(huán)和靜環(huán)的總稱（下同），是構(gòu)成機械密封主要的元件。一、密封環(huán)在很大程度上決定了機械密封的使用性能和壽命，對它提出了一些要求。1）有足夠的強度和剛度。在工作條件下（如壓力、溫度和滑動速度等）不損壞，變形應(yīng)盡量的小，工作條件波動時仍能保持密封性。2）密封端面應(yīng)有足夠的硬度和耐腐蝕性，以保證工作條件下有滿意的使用壽命。3）密封環(huán)應(yīng)有良好的耐熱沖擊能力。為此，要求材料有較高的導(dǎo)熱系數(shù)和較小的線膨脹系數(shù)，承受熱沖擊時不至于開裂。4）密封環(huán)匹配應(yīng)有較小的摩擦系數(shù)和良好的自潤滑性，密封環(huán)材料與密封流體還要有很好的浸潤性。工作中如發(fā)生短時間的干摩擦，不損傷密封端面。5）密封環(huán)應(yīng)力求簡單、對稱并優(yōu)先考慮用整體型結(jié)構(gòu)。也可采用組合式（如鑲裝式）密封環(huán)，盡量避免用密封端面噴涂式結(jié)構(gòu)。6）密封環(huán)要容易加工制造，安裝和維修要方便，價格要低廉。二、摩擦副匹配要考慮的因素摩擦副一般都選擇一軟一硬的配對。目前軟環(huán)多選用破一石墨（以下簡稱石墨）。蕪湖M481釜用機械密封件。</p><div

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)，無組合應(yīng)力產(chǎn)生／也無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)的缺點是，隨著時間的推移，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。安慶M481釜用機械密封件。鐵嶺207型釜用機械密封</p><p

磨損較均勻；從受力角度考慮過窄不利，破壞和變形的可能性增加了＞俐，密封端面的直徑又是載荷系數(shù)的函數(shù)。因此，密封端面的寬度應(yīng)綜合考慮。一般地講，對普通介質(zhì)密封端面隨直徑的增大而加寬。對于輕烴類介質(zhì)，端面寬度比在普通介質(zhì)中寬一些：而高速機械密封，端面寬度相對地窄一些，否則發(fā)熱量太大，不能正常運轉(zhuǎn)，一般在3mm左右。環(huán)直徑（mm、環(huán)寬（mm）－20～602～460～1004～6100～2005—7四、密封環(huán)的技術(shù)要求：1）密封端面的平面度不大于0．0009mm（即三個單色光干涉帶）；硬質(zhì)材料密封端面粗糙度Ra值不大于0．2μm（相當于Δ10）；軟質(zhì)材料密封端面粗糙度Ra值不大于0．4μm(相當于Δ9)，表面不應(yīng)有裂紋、劃傷、氣孔和疏松等影響使用性能的缺陷。2）密封環(huán)的密封端面與輔助密封圈接觸的端面平行度按GBll84－80的7級精度規(guī)定。3）密封環(huán)端面與安裝輔助密封圈的內(nèi)（或外）圓表面的垂直度應(yīng)按GBll84－80的7級精度的規(guī)定。4）密封環(huán)與輔助密封圈接觸部位的表面粗糙度凡值不大于3．2μm；外圓或內(nèi)孔尺寸公差為hg或Hg。上述要求是對普通泵用機械密封的密封環(huán)而言，對轉(zhuǎn)速較低的釜用機械密封可適當放寬或參考相應(yīng)的標準，而對高速機械密封則要求更高。五、平面度平面度。三門峽M481釜用機械密封件</p><p
