圖3-22)Y4D型金屬波紋管密封是Eagle公司用于低壓(()，溫度-200~+400℃密封。波紋管采用Inconel718材料，這種合金的耐氧化性能可達(dá)980℃，薊州區(qū)ITT泵用機(jī)械密封件選型，在-196℃的低溫下屈服強(qiáng)度可達(dá)1426N/mm2.因此，Inconel718在高低溫條件下都適用.尤里卡裝置中凡高溫的減壓渣油，KSK油，輕、重瓦斯油的密封都采用Y4D型金屬波紋管機(jī)械密封.(圖3-10)雖然59B型密封的使用溫度范圍為-50~十230℃，如果泵送介質(zhì)借助于輸送裝置，通過冷卻器再進(jìn)人密封，則59B型密封仍可用于介質(zhì)溫度大于230℃的場(chǎng)合.例如，芳烴裝置釜液泵GA-116AB的介質(zhì)溫度為290℃，就是采用外冷卻的59B型密封.4.上海水泵廠605系列波紋管機(jī)械密封介紹上海水泵廠引進(jìn)美國(guó)EG&GSEALOL公司技術(shù)，已生產(chǎn)多種系列的密封，其中605系列是焊接波紋管機(jī)械密封，它的型號(hào)、規(guī)格和使用性能如表10-2所示.高壓機(jī)械密封通常認(rèn)為，當(dāng)機(jī)械密封的工作壓力超過4~5MPa時(shí)就視作高壓，有的密封公司把工作壓力達(dá)到3MPa就作為高壓;有的公司以PV值大小來衡量;有的公司則將壓力和溫度一起考慮.一般認(rèn)為在高壓下，薊州區(qū)ITT泵用機(jī)械密封件選型，由于機(jī)械和熱變形危害機(jī)械密封的功能和可靠性，壓力越高，危害性越大，薊州區(qū)ITT泵用機(jī)械密封件選型.所以，用于極高壓力的密封比標(biāo)準(zhǔn)型密封要求設(shè)計(jì)改進(jìn)。巫山石家莊工業(yè)泵泵用機(jī)械密封件大全。薊州區(qū)ITT泵用機(jī)械密封件選型</p><div

且接觸應(yīng)力不均勻，使之產(chǎn)生機(jī)械變形；二是由于使用溫度較高（或過低），材料物理性能（主要是線膨脹系數(shù)）的差異使硬質(zhì)合金環(huán)和環(huán)座的配合部位不能同步脹縮，過盈量發(fā)生變化，接觸應(yīng)力也隨著發(fā)生變化，這種變化對(duì)密封環(huán)的使用產(chǎn)生影響。密封端面變形破壞了平面度，更有甚者喪失過盈，使聯(lián)接失效，硬質(zhì)合金環(huán)熱裝式密封環(huán)目前有三種結(jié)構(gòu)，圖23a是制造廠早期生產(chǎn)的，結(jié)構(gòu)較為簡(jiǎn)單。但是由于硬質(zhì)合金環(huán)和輔助密封圈接觸，一旦硬質(zhì)合金環(huán)松脫，運(yùn)轉(zhuǎn)時(shí)輔助密封圈被嚴(yán)重磨損，會(huì)出現(xiàn)大量泄漏。而圖23b是在圖23a的基礎(chǔ)上改進(jìn)的，輔助密封圈不和硬質(zhì)合金環(huán)接觸，不存在上述缺陷，只是硬質(zhì)合金環(huán)和環(huán)座之間有輕微泄漏。為了減少硬質(zhì)合金環(huán)密封端面的不均勻變形，環(huán)座的熱裝部位內(nèi)外設(shè)置環(huán)形槽（圖23c），使硬質(zhì)合金環(huán)外圓柱面的接觸應(yīng)力趨于均勻，以減少碳化鎢環(huán)的變形，使用效果較好。焊接的組合式密封環(huán)特點(diǎn)為克服熱裝式密封環(huán)松脫的缺陷，出現(xiàn)了焊接的密封環(huán)（圖24）。所用的硬質(zhì)合金是以Cr3C2為硬質(zhì)相、Ni為粘結(jié)相的燒結(jié)合金材料。耐腐蝕優(yōu)于YG6等硬質(zhì)合金，高溫下具有優(yōu)異的抗氧化性能，在1000℃空氣中加熱2小時(shí)無任何變化。但是導(dǎo)熱性能較差，*為YG6的1／3；線膨脹系數(shù)大。長(zhǎng)春泵用機(jī)械密封件規(guī)格型號(hào)麗江凝結(jié)水泵泵用機(jī)械密封件大全。</p><div

要將軸封部分的溫度設(shè)計(jì)為0℃，這時(shí)用作氣體密封，密封圈可用普通O形或V形密封圈。密封結(jié)構(gòu)是與泵體結(jié)構(gòu)相適應(yīng)，常用的低溫泵采用立式結(jié)構(gòu).3.輔助裝置(1)要盡可能加大沖洗量，加強(qiáng)冷卻措施，或提高密封腔內(nèi)壓力，來控制液溫升高所引起的氣化現(xiàn)象，要***避免從泵出口端裝沖洗管線來沖洗密封端面，因?yàn)樵诘蜏叵?，這種沖洗管線內(nèi)液體會(huì)氣化.所以，一般采逆流沖洗方式.(2)防止單端面密封在泵停轉(zhuǎn)過程中大氣中水分與密封接觸使邊緣結(jié)冰，可用甲醇等化冰劑加以溶解，阻封部分也可通人氮?dú)飧蓺饧右员Ｗo(hù).總之，既要充分冷卻又要采取保冷措施。(3)在高于密封面的部位裝設(shè)排氣管線，這樣，如果產(chǎn)生氣體也可從排氣管線逸出。有關(guān)低溫泵的輔助裝置見第七章***節(jié)低溫泵輔助系統(tǒng)。二、低溫甲烷泵機(jī)械密封低溫泵通常是立式結(jié)構(gòu)，密封腔設(shè)在泵的上部，密封結(jié)構(gòu)為雙端面平衡型機(jī)械密封。低溫泵的結(jié)構(gòu)及布置如圖10-19所示。1.低溫泵的結(jié)構(gòu)特點(diǎn)(1)筒形結(jié)構(gòu)，不必?fù)?dān)心低溫時(shí)發(fā)生變形.(2)一級(jí)葉輪位于底部，通過增減柱形筒體的長(zhǎng)度(圖10-19中的葉輪只列出二級(jí)，實(shí)際有十多級(jí))，.來適應(yīng)葉輪級(jí)數(shù)的變化。(3)液體從上向下進(jìn)人葉輪，由吸人端排氣從而起到有效的氣體分離器作用。(4)立式結(jié)構(gòu)排氣順暢。</p><p> 或內(nèi)徑D1)的極限偏差按表9-5的規(guī)定。彈簧自由高度Ho的極限偏差按表9-6的規(guī)定。彈簧在壓縮到全變形量的10%時(shí)，其正常節(jié)距圈不應(yīng)接觸。兩端面經(jīng)過磨削的彈簧，在自由狀態(tài)下，彈簧軸心線對(duì)兩端面的垂直度偏差<。兩端面并緊并磨平的彈簧，支承圈磨平部分大于或等于3/4圈。其表面粗糙度Ra為，端頭厚度不小于d/8。彈簧表面應(yīng)光滑，不得有裂紋、起刺等肉眼可見的有害缺陷.近幾年很多引進(jìn)機(jī)械密封使用了波形彈簧，其中纏繞式波型彈簧用量較多。纏繞式波形彈簧結(jié)構(gòu)見圖9-3，其具有強(qiáng)度高、柔性好、結(jié)構(gòu)形式緊湊、安裝空間小等優(yōu)點(diǎn)。它是用專用纏繞彈簧設(shè)備加工的，纏繞式波型彈簧技術(shù)要求如下:纏繞式波型彈簧的波峰應(yīng)呈圓弧形，不允許出現(xiàn)平頂或尖頂。多層纏繞式波型彈簧相鄰上下層的波峰及波谷要對(duì)齊.圓周方向角度錯(cuò)位不大于5°。多層纏繞式波型彈簧相鄰上下層的徑向錯(cuò)邊不大于。纏繞式波型彈簧內(nèi)外徑尺寸偏差應(yīng)符合表9-7的規(guī)定。纏繞式波形彈簧自由高度尺寸偏差應(yīng)符合表9-8、表9-9的規(guī)定。纏繞式波形彈簧必須經(jīng)過消除應(yīng)力處理。殘余變形不應(yīng)超時(shí)(單片波型彈簧小于)。同一個(gè)纏繞式波形彈簧各波高度差應(yīng)不超過表9-10及表9-11的規(guī)定(多層纏繞式波型彈簧*指中間層的各波高度)。韶關(guān)凝結(jié)水泵泵用機(jī)械密封件維修。</p><div

七、目前應(yīng)用的密封種類根據(jù)制造方法和材料的不同，目前應(yīng)用的密封環(huán)有整體式密封環(huán)（用同一種材料制造）、組合式密封環(huán)、表面堆焊硬質(zhì)合金和噴涂陶瓷等多種結(jié)構(gòu)。整體式密封環(huán)種類：這種密封環(huán)因用同一種材料制成，材料的性能在密封環(huán)的各個(gè)部位均勻一致，沒有組合式密封環(huán)泄漏和分離的缺陷，也沒有電化學(xué)腐蝕的可能。制造軟環(huán)大都用石墨，制造硬環(huán)時(shí)可用各種合金鋼，如軸承鋼（GCr9）、高速鋼（W18CrV）及其他合金鋼（如40Cr、3Cr13等），也有的用合金鑄鐵（如硅、鉻和鎳鑄鐵）。采用這些材料時(shí)，都要輔之以適當(dāng)?shù)臒崽幚砉に嚕蕴岣咂溆捕群湍湍バ?。這類材料價(jià)格較低，如果使用恰當(dāng)，也有較長(zhǎng)的壽命。為了進(jìn)一步提高硬度和延長(zhǎng)使用壽命，可采用硬質(zhì)合金制造。常用的硬質(zhì)合金為鉆基碳化鎢，性能較好，但價(jià)格高。鋼結(jié)硬質(zhì)合金的價(jià)格較低。為了提高在腐蝕介質(zhì)中的耐蝕性，有鎳基碳化鎢，而哈氏合金有更高的耐蝕性，但價(jià)格昂貴。此外，還有用碳化硅及其他陶瓷材料制造的密封環(huán)。出現(xiàn)組合式由封環(huán)的原因碳化鎢等材料有優(yōu)良的性能，但是價(jià)格高，加工困難，限制了它的使用。為解決這個(gè)矛盾，出現(xiàn)了組合式密封環(huán)。密封端面采用硬質(zhì)合金，密封環(huán)的基體。巫山襄樊五二五泵用機(jī)械密封件廠家。長(zhǎng)春泵用機(jī)械密封件規(guī)格型號(hào)</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(duì)普通介質(zhì)密封端面隨直徑的增大而加寬。對(duì)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(jī)械密封，端面寬度相對(duì)地窄一些，否則發(fā)熱量太大，不能正常運(yùn)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(gè)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(dāng)于Δ10）；軟質(zhì)材料密封端面粗糙度Ra值不大于0．4μm(相當(dāng)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(jí)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(jí)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(duì)普通泵用機(jī)械密封的密封環(huán)而言，對(duì)轉(zhuǎn)速較低的釜用機(jī)械密封可適當(dāng)放寬或參考相應(yīng)的標(biāo)準(zhǔn)，而對(duì)高速機(jī)械密封則要求更高。五、平面度平面度。薊州區(qū)ITT泵用機(jī)械密封件選型</p><p
