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(jī)械密封為主，結(jié)合其它結(jié)構(gòu)型式（包括進(jìn)口的密封），就有關(guān)的技術(shù)問題和故障分析。第二節(jié)機(jī)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(jī)械密封**主要的元件。一、密封環(huán)在很大程度上決定了機(jī)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(qiáng)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）。黔江區(qū)宙斯泵用機(jī)械密封件廠蕪湖石家莊工業(yè)泵泵用機(jī)械密封件選型。</p><div

填料密封已滿足不了要求;二是使用條件越來越苛刻，安全要求也越來越高，減少泄漏，防止污染環(huán)境的呼聲促使設(shè)計(jì)、生產(chǎn)部門采用機(jī)械密封;三是釜用機(jī)械密封的結(jié)構(gòu)不斷改進(jìn)以及與其配套的輔助裝置普遍得到采用，使密封效果更良好，從而節(jié)省了維修費(fèi)用.有人做過統(tǒng)計(jì)，盡管機(jī)械密封的凈購置費(fèi)用比填料密封高，但安裝使用之后，機(jī)械密封的維修費(fèi)用只占填料密封維修費(fèi)用的1/20，五年后總費(fèi)用，機(jī)械密封比填料密封低一半.一、釜用機(jī)械密封與泵用機(jī)械密封的區(qū)別1.釜用機(jī)械密封大多數(shù)為立式，少數(shù)為傾斜式，極個別為水平式.一般計(jì)算機(jī)械密封端面比壓都不考慮旋轉(zhuǎn)零件的自重.2.泵用機(jī)械密封的軸徑多數(shù)在100mm以下，而釜用機(jī)械密封的軸徑在100mm以上也很多.泵用機(jī)械密封的重量一般從幾百克到幾公斤，.而一套釜用機(jī)械密封的重量有時達(dá)幾百公斤到一千公斤以上。所以，在設(shè)計(jì)時要考慮安裝、檢修所需的起吊裝置.3.釜用機(jī)械密封的密封介質(zhì)多數(shù)為氣相.因此，釜用密封的端面比壓要比泵用密封的端面比壓高.4.釜用密封多數(shù)為雙端面、平衡型結(jié)構(gòu)，此外，為了安裝和檢修方便，也用剖分式結(jié)構(gòu)和易檢拆結(jié)構(gòu).二、上裝式釜用機(jī)械密封上裝式釜用密封應(yīng)用較廣，它占引進(jìn)的斧用機(jī)械密封95%以上.例如。</p><p> 纏繞式波形彈簧材料可選用SU302、SUS304、SUA631J1和SUSS632等，材料的化學(xué)成應(yīng)符合GB/T3280-2008、GB/T4238-2007的規(guī)定，材料的尺寸精度要按表9-12規(guī)定。扁帶材料外表光滑，無凹坑、劃傷、斷裂、裂縫和其他物理缺陷，邊緣為圓形。纏繞式波形彈簧工作負(fù)荷的允許偏差為該負(fù)荷的10%。各種類型纏繞式波形彈簧的疲勞性能應(yīng)符合表9-13要求。3形橡膠密封圈的技術(shù)要求由于橡膠是彈性材料，在負(fù)荷作用下發(fā)生變形，尤其是在壓力高的場合合下，會使密封圈擠入密封間隙，影響浮動性而使密封失效。因此。要根據(jù)使用壓力合理選擇O形橡膠密封圈的硬度和其截面直徑。一般高壓時選擇硬度較高的密封圈.低壓時選擇硬度較低的密封圈。常用橡膠O形圈的硬度為邵氏70±5。制造機(jī)械密封用O形圈的模具分模面盡量避開內(nèi)外側(cè)及上下側(cè)的工作面，一般采用45°開模，以保證良好的密封性能。截面尺寸要均勻，其截面形狀參考圖，不得存在凹凸不平、氣泡、雜質(zhì)等缺陷。O形橡膠密封圈內(nèi)徑極限偏差見表9-14，截面直徑偏差見表915。O形橡膠密封圈產(chǎn)品非工作面上用標(biāo)記膠或油漆點(diǎn)表示膠料種類，標(biāo)記見表9-16。黔江區(qū)宙斯泵用機(jī)械密封件廠家。</p><div

一、高位差平衡罐裝置高位差平衡罐裝置與釜用機(jī)械密封組合型式見圖1一14。高位差平衡罐裝置的主要設(shè)備是一個帶有液面計(jì)的平衡罐，罐內(nèi)裝有密封液，罐底部與密封腔的進(jìn)出口連接，頂部與釜內(nèi)連通。釜內(nèi)的壓力可以直接加壓在上面。平衡罐安裝的位置要比反應(yīng)釜高出一定距離，釜內(nèi)壓力加上這段液位差壓力，使密封腔的壓力稍大于釜內(nèi)壓力，且壓差始終保持不變，使密封保持在一個穩(wěn)定的工作狀態(tài)。二、活塞增壓裝置活塞增壓裝置與釜用機(jī)械密封組合型式見圖1-15。該裝置是一種壓力傳遞機(jī)構(gòu)，平衡罐中間裝有一平衡活塞，平衡罐上部與密封腔連通，下部與釜內(nèi)連通，釜內(nèi)的壓力通過平衡活塞傳遞到密封腔。由于活塞體上端的承壓面積比活塞體下端的承壓面積減少了一根活塞桿d的面積，則密封液壓力按兩端承壓面積反比例地增加。從而保證了良好的密封條件。設(shè)計(jì)活塞兩端的承壓面積之比時，應(yīng)根據(jù)所要求的密封腔與釜內(nèi)壓力差來計(jì)算。此外，活塞桿上裝有彈簧，調(diào)節(jié)好彈簧的壓縮量，使彈簧張力正好抵消活塞上0形圈對缸壁的摩擦力，以減少計(jì)算值的誤差。三、氮?dú)馄砍鋲貉b置氮?dú)馄砍鋲貉b置與釜用機(jī)械密封組合型式見圖1-16。該裝置與高位差平衡罐裝置相同的是均采用平衡罐補(bǔ)充密封液。寶雞宙斯泵用機(jī)械密封件大全。黔江區(qū)宙斯泵用機(jī)械密封件廠</p><p
