泵用機械密封按結(jié)構(gòu)分類的基本形式有單端面機械密封、雙端面機械密封和串聯(lián)機械密封。由一對密封端面組成的為單端面機械密封；由兩對密封端面組成的為雙端面機械密封；由兩套或兩套以E同向布置單端面機械密封組成的機械密封為串聯(lián)機械密封。下面主要分別說明兩種機械密封的結(jié)構(gòu)特點供了解單端面與雙端面機械密封的區(qū)別。1、單端面機械密封單端面機械密封結(jié)構(gòu)簡單，如圖單端面機械密封結(jié)構(gòu)圖所示、制造成本低廉，安裝、使用方便，一般用于油、水、有機溶劑及腐蝕性介質(zhì)。通常使用單端面密封的泵類產(chǎn)品有立式單級管道離心泵、臥式離心泵單端面機械密封結(jié)構(gòu)圖如下2、雙端面機械密封有壓雙重機械密封(雙端面機械密封)多數(shù)用于易燃、易爆，圖木舒克渣漿泵用機械密封廠家、有毒、含顆粒及潤滑性差的介質(zhì)，通常使用時需配備密封輔助系統(tǒng)，即在兩端面間的密封腔中通入隔離流體，圖木舒克渣漿泵用機械密封廠家，圖木舒克渣漿泵用機械密封廠家，從而改善機械密封的潤滑和冷卻條件，如圖雙端面機械密封結(jié)構(gòu)圖所示。雙端面機械密封結(jié)構(gòu)圖如下使用雙端面機械密封的泵類產(chǎn)品有：氟塑料離心泵或者IH不銹鋼化工泵等3、單端面與雙端面機械密封零件及相應術語密封環(huán)：機械密封中其端面垂直于旋轉(zhuǎn)軸線相互貼合并相對滑動的兩個環(huán)形零件稱密封環(huán)。貴陽福斯泵用機械密封廠家。圖木舒克渣漿泵用機械密封廠家</p><div

2)裝配順序①機械密封靜止部件的組裝：a.將防轉(zhuǎn)銷裝入密封端蓋相應的孔內(nèi);b.將靜環(huán)密封圈套在靜環(huán)上，將靜環(huán)裝入密封端蓋內(nèi)，要注意使防轉(zhuǎn)銷進入靜環(huán)凹槽內(nèi)。安裝壓蓋時，注意不要使靜環(huán)碰軸。螺栓應分幾次均勻擰緊。②機械密封旋轉(zhuǎn)部件組裝：將機械密封的旋轉(zhuǎn)部件依照先后次序逐個組裝到軸上。若有軸套，則要在外面把機械密封的旋轉(zhuǎn)部件依次組裝到軸套上，然后將裝有機械密封旋轉(zhuǎn)部件的軸套裝到軸上。③端蓋裝在密封體上，并用螺釘均勻擰緊。④盤動試車是否輕松，若盤不動或吃力，則應檢查裝配尺寸是否正確。4、機械密封運轉(zhuǎn)的故障處理(1)開始就泄露①檢查裝配質(zhì)量是否符合技術要求，彈簧壓縮量是否符合規(guī)定。②檢查動環(huán)、靜環(huán)的密封端面是否損壞。③檢查密封端面是否端正。(2)運轉(zhuǎn)中泄露量突然過多，此時應停車進行檢查①檢查動環(huán)、靜環(huán)密封端面的磨損情況與表面質(zhì)量的變化，若已破壞則應返修或更換新件。②檢查動環(huán)、靜環(huán)的輔助密封圈的安裝位置是否正確(如V型圈的唇口應朝向壓力端)、有無損壞。若安裝有誤則重新安裝，若已損壞則應重新?lián)Q件。③檢查密封腔體內(nèi)是否混入固體雜質(zhì)，傳動座內(nèi)是否充滿了雜質(zhì)，影響動環(huán)的軸向浮動和彈簧的補償。④檢查緊定螺釘是否松動。圖木舒克渣漿泵用機械密封廠家河北渣漿泵用機械密封型號。</p><div

1、調(diào)溫器（1）為改善攪拌軸支承穩(wěn)定性，降低密封腔的工作溫度，提高使用性能，應選配調(diào)溫器。它的選用原則見釜用機械密封冷卻和潤滑的第1條及表6、表7。（2）適用于單端面機械密封的調(diào)溫器XT型和LT型（見圖20）。圖20XT、LT型調(diào)溫器結(jié)構(gòu)圖（3）適用雙端面機械密封的調(diào)溫器CT型（見圖21）。圖21CT型調(diào)溫器結(jié)構(gòu)圖（也可與機封做成一體）2、循環(huán)保護系統(tǒng)（1）循環(huán)保護系統(tǒng)的分類：1）A循環(huán)系統(tǒng)——GCL型平衡罐熱虹吸流程；2）B循環(huán)系統(tǒng)——GDL型平衡罐強制循環(huán)系統(tǒng)；3）C循環(huán)系統(tǒng)——開式循環(huán)系統(tǒng)；4）D循環(huán)系統(tǒng)——D04-17型液壓泵站強制循環(huán)系統(tǒng)。（2）循環(huán)系統(tǒng)流程圖（見圖22）圖22機械密封循環(huán)保護系統(tǒng)示意圖（3）循環(huán)保護系統(tǒng)的選用原則，見釜用機械密封冷卻和潤滑的第1條及表6、表7。3、G型平衡罐是釜用機械密封A、B循環(huán)系統(tǒng)配套使用的平衡罐，它的型式、作用及使用等具體見后期推出的“G型平衡罐的使用說明”。4、D04-17型液壓泵站D04-17型液壓泵站是專為釜用機械密封“D循環(huán)系統(tǒng)”配套的液壓供油裝置，它具有潤滑、調(diào)溫、調(diào)壓、濾除雜質(zhì)等功能，可確保雙端面機械密封穩(wěn)定可靠地運行，其詳細使用情況見“D04-17型液壓泵站使用說明書”。</p><p> 也可采用內(nèi)裝式結(jié)構(gòu).實際上，引進裝置工藝泵的機械密封絕大部分為內(nèi)裝式密封.輸送危險性大的介質(zhì)，可選用雙端面密封結(jié)構(gòu)，并引人隔離液保護.此外，也可采用彈簧帶有保護層的措施.例如，彈簧外加套塑料軟管或噴涂一層防腐層，圖10-22為彈簧加保護套的密封結(jié)構(gòu).2.材質(zhì)上選用耐腐蝕材科推薦耐蝕材質(zhì)，這是根本出路.石油化工引進裝置所用.的機械密封大部分從材質(zhì)上解決了耐蝕問題，·所以在國外大的密封公司的樣本或手冊中都備有不同介質(zhì)所對應的密封型號選定表.3.對泄漏的腐蝕性或有毒的介質(zhì)進行收集、安全排放或處理后排放.例如，有的帶回收液盤，有的裝排放管線，圖上標明排放至安全區(qū)域.揚子石油化工公司引進裝置應角的機械密封大部分為耐腐蝕的密封，典型的如英國克蘭公司的59U、59B和10T型，日本比拉公司的BB8型和Eagle公司Y4D。型，西德布格曼公司TF型和Wernert公司橡膠波紋管(ConcertinaWalls)型密封.國內(nèi)用于耐腐蝕泵用機械密封有:151、152、153、154型.結(jié)構(gòu)如圖10-23、10-24、10-25、10-26所示.含有磨料介質(zhì)和高粘度介質(zhì)的機械密封密封介質(zhì)一般總有雜質(zhì)，所以要經(jīng)過處理，就是經(jīng)過處理的介質(zhì)也會在工藝過程中產(chǎn)生結(jié)晶、凝固和反應物析出。嘉峪關襄樊五二五泵用機械密封選型。</p><div

src="https://tyunfile.71360.com/UploadFile/ygebgm/637324990573378906/8594308.png"></div><p> 一般選用耐老化性能較好的丁晴橡膠。當輸送介質(zhì)在-50～200℃時，選用氟橡膠更為合適。因為它除了耐油耐熱外，機械強度大也是其主要特征。在化工泵中，由于所輸送介質(zhì)具有腐蝕性，所以一般選用聚四氟乙烯做為墊片材料。隨著泵使用的領域越來越***，所輸送介質(zhì)種類也越來越多，因此在選用墊片材質(zhì)時應查閱相關資料或通過實驗后再做出正確選擇。墊片失效的原因主要有下列幾種情況：1、墊片材質(zhì)內(nèi)部組織或厚度不均勻，以及使用了帶有裂縫或折皺的紙板，使墊片本身形成了間隙，當作用在墊片上的力使墊片所產(chǎn)生的彈性變形不足以完全填充這些間隙時，泄漏也就不可避免了。2、墊片的材質(zhì)與所輸送的介質(zhì)不相適應。由于泵所輸送化工產(chǎn)品化學性質(zhì)的多樣性，以及為提高燃油的燃燒值或改變其燃燒后的生成物而在燃油中增加入了一些少量的添加劑后而使燃油的某些性質(zhì)發(fā)生變化，所以選擇和輸送介質(zhì)相適的墊片材質(zhì)并非易事，因而也經(jīng)常發(fā)生由于不相適應而使墊片發(fā)生侵蝕而產(chǎn)生泄漏的現(xiàn)象。3、作用在密封墊片上的壓力不足。由于密封面上總是存在著微觀的凹凸不平，有時還在密封面上加工出若干環(huán)形溝槽，若保證密封，就必須對密封墊片施加足夠大的壓力，使其發(fā)生彈性或塑性變形以填充這些間隙。延安福斯泵用機械密封選型。圖木舒克渣漿泵用機械密封廠家</p><p style="text-indent:25px">內(nèi)蒙古福斯泵用機械密封型號。圖木舒克渣漿泵用機械密封廠家</p><p> 焊接金屬波紋管的彈率的計算由于焊接金屬波紋管機械密封不用彈簧，彈性力完全由波紋管產(chǎn)生，因此波紋管設計時要考慮其彈率。一般將波紋管的彈率設計得小些，當要求一定的彈力時，波紋管的壓縮量就要適當?shù)丶哟?。運轉(zhuǎn)相當長時間后，如果密封端面磨損，波紋管自動補償，而彈力降低不會大，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。工作時每個波的變形以小為宜，為保證一定的壓縮量，要適當增加波數(shù)，保持波距。一般波數(shù)取16～20，溫度和壓力高時波數(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。實際工作中可在彈簧測力計上測量其彈率。普通彈簧的彈率計算在一般“機械零件”書上能找到，故在此不作介紹。非對稱型波紋管焊接金屬波紋管機械密封以其結(jié)構(gòu)簡單、伸縮性好和耐高溫等優(yōu)點，得到了日益***的應用，尤其是高溫泵的密封中。圖木舒克渣漿泵用機械密封廠家</p></p><br
