如果采用串聯(lián)密封的方式，內(nèi)側(cè)密封必須能承受反壓，且需要采用自沖洗方案（一般為plan11或plan13）。PLAN54（采用外引密封液的雙端面密封）方案描述：外設(shè)加壓隔離液儲罐或系統(tǒng)提供清潔的液體給密封腔，循環(huán)用外部泵或壓力系統(tǒng)來完成，儲液罐壓力大于被密封的工藝介質(zhì)壓力。采用原因：分離工藝流體，零流程排放，密封不能促進(jìn)循環(huán)。應(yīng)用場合：應(yīng)用于雙端面承壓密封（雙封），高蒸汽壓流體，輕質(zhì)烴，危險/有毒流體，傳熱流體，臟/腐蝕性或聚合體。PLAN62（外沖洗或急冷防止密封面堆積固體顆粒）方案描述：由外部提供急冷液，在密封的接觸大氣端進(jìn)行外部冷卻，冷卻流體主要為蒸汽、氮和水。采用原因：防止固體在機封的大氣端集結(jié)，ZB6機械密封，配合小間隙節(jié)流襯套使用，ZB6機械密封。防止結(jié)冰。應(yīng)用場合：用于單端面機封，排除氧氣的存在，防止焦化，沖走動態(tài)密封元件附近不想要的物質(zhì)（如腐蝕性或含鹽的工況）。PLAN65（帶浮子液位開關(guān)測量密封泄露量）方案描述：外部排液管道布置是，用浮子液位開關(guān)測量密封泄漏量，對高泄漏量進(jìn)行報警，ZB6機械密封，液位開關(guān)下游的孔板，其孔徑通常為5mm，設(shè)置在立管腿上。機封在大氣端，帶泄漏檢查的外部排水。采用原因：單獨使用或與62方案一起使用，用于間隙很小的節(jié)流襯套。南通109-20機械密封件。ZB6機械密封</p><div

要掌握機械密封檢修與維護，首先要知道機械密封的工作原理。機械密封是由兩塊密封元件（靜環(huán)與動環(huán)）垂直于軸的、光潔而平直的表面相互貼合，并作相對轉(zhuǎn)動而構(gòu)成的密封裝置。它是靠密封介質(zhì)的壓力在旋轉(zhuǎn)的動環(huán)和靜環(huán)的接觸表面（端面）上產(chǎn)生適當(dāng)?shù)膲壕o力，使這兩個端面緊密結(jié)合，端面間維持一層極薄的液體膜而達(dá)到密封目的的。這層液體膜具有液體動壓力與靜壓力，起著潤滑和平衡力的作用。水泵機械密封的檢修工藝主要有以下個方面：一．機械密封的清掃與檢查機械密封的工作原理要求機械密封內(nèi)部無任何雜質(zhì)。在組裝機械密封前要徹底清掃動環(huán)、靜環(huán)、軸套等部件。重點檢查：1、動靜環(huán)（5、6）表面是否存在劃痕、裂紋等缺陷，這些缺陷存在會造成機械密封嚴(yán)重漏泄。有條件的可以用**工具檢查密封面是否平整，密封面不平整，壓力水會進(jìn)入組裝后機械密封的動靜環(huán)密封面，將動靜環(huán)分開，機械密封失效。必要時可以制作工裝在組裝前水壓試驗。2、檢查動靜環(huán)座（2）是否存在影響密封的缺陷。如動靜環(huán)座與動靜環(huán)密封膠圈配合表面是否存在傷痕等缺陷。3、檢查機械密封補償彈簧（7）是否損壞及變形，倔強系數(shù)是否變化。4、檢查密封軸套（8）是否存在毛刺、溝痕等缺陷。錫林郭勒機械密封25-LP-D-S32-D20/60-DE銅陵橡膠波紋管機械密封件。</p><div

通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤滑的作用。然而，在填料盒內(nèi)，采用彈簧負(fù)載和液體壓力相結(jié)合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會影響接觸面之間形成液體薄膜，導(dǎo)致熱量增加和過早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進(jìn)行研磨。然后，采用單色光源的光柵板對其檢測。從這一觀點出發(fā)，對這些密封接觸面必須小心處理，并嚴(yán)格按照安裝說明，保證密封面得到適當(dāng)?shù)谋Ｗo和正確就位，這一點是非常重要的。密封的靈活性選擇主軸的軸向和徑向運動需要與彈簧之間保持一定的靈活性，以保證接觸面之間的密封。然而，只能提供一定程度的靈活性。液泵的機械狀況及其長度直徑比(一種主軸的直徑與其延伸長度之比的衡量方式，比值越低越好)對密封的可靠性起著重要的作用。密封的靈活性一般由一個大型主彈簧和一系列小彈簧或波紋密封裝置提供保證。</p><p> 如油渣泵、回?zé)捰捅?、常減壓塔底泵等常見的失效現(xiàn)象。在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)進(jìn)入密封面、抽空等情況下，都會導(dǎo)致環(huán)面出現(xiàn)徑向裂紋；b）石墨炭化是使用碳-石墨環(huán)時密封失效的主要原因之一。由于在使用中，如果石墨環(huán)一旦超過許用溫度（一般在-105～250℃）時，其表面會析出樹脂，摩擦面附近樹脂會發(fā)生炭化，當(dāng)有粘結(jié)劑時，會發(fā)泡軟化，使密封面泄漏增加，密封失效；c）輔助密封件（如氟橡膠、乙丙橡膠、全橡膠）在超過許用溫度后，將會迅速老化、龜裂、變硬失彈?，F(xiàn)在所使用的柔性石墨耐高溫、耐腐蝕性較好，但其回彈性差。而且易脆裂，安裝時容易損壞。6、由于密封端面的磨損而造成的密封失效a）摩擦副所用的材料耐磨性差、摩擦系數(shù)大、端面比壓（包括彈簧比壓）過大等,都會縮短機械密封的使用壽命。對常用的材料，按耐磨性排列的次序為：碳化硅-碳石墨、硬質(zhì)合金-碳石墨、陶瓷-碳石墨、噴涂陶瓷--碳石墨、氮化硅陶瓷--碳石墨、高速鋼--碳石墨、堆焊硬質(zhì)合金--碳石墨。b）對于含有固體顆粒介質(zhì)，密封面進(jìn)入固體顆粒是導(dǎo)致使密封失效的主要原因。固體顆粒進(jìn)入摩擦副端面起研磨劑作用，使密封發(fā)生劇烈磨損而失效。密封面合理的間隙。新吳區(qū)波紋管機械密封件。</p><div

2非金屬環(huán)腐蝕石墨環(huán)被腐蝕也是機械密封是小的重要原因之一，斷面溫度過高、浸漬樹脂選擇不當(dāng)、浸漬樹脂深度不夠等都是導(dǎo)致石墨環(huán)被腐蝕的原因。當(dāng)石墨環(huán)處于氧化性介質(zhì)中時，出冷卻不良或產(chǎn)生摩擦?xí)r，環(huán)境產(chǎn)生三四百度會促使石墨與氧化性介質(zhì)發(fā)生氧化反應(yīng)，使端面變得失去性能。3輔助密封圈及接觸部位的腐蝕不同的材料有不同的抗腐蝕性，輔助密封圈的材料一般選取具有彈性的橡膠，而橡膠被腐蝕后會使表面變得異常粗糙，失去原有的彈性。并且橡膠的耐高溫性能比較差，一般不超過兩百度。與輔助密封圈相接觸的部位處于相對靜止的狀態(tài)，二者之間的縫隙以及摩擦等都會是腐蝕產(chǎn)生的原因，并且腐蝕面一般較寬、較深。機泵機械密封的故障表現(xiàn)生產(chǎn)過程中，機泵機械密封泄露的原因有其本身的原因及外部原因，材料的選擇以及安裝方式和使用方式都會引起機械密封的失效，失效時的故障表現(xiàn)也各有差異，學(xué)會通過不同故障表現(xiàn)并做出正確及時的判斷能夠?qū)嶋H生產(chǎn)提供強有力的支持。1靜壓實驗時泄露機械密封裝置在安裝時由于員工不細(xì)心，經(jīng)常會使密封端面被碰傷以至于變形和損壞，清理不夠徹底，使得機械密封夾有顆粒狀雜質(zhì)。阜陽YM109機械密封件。朔州機械密封SE2C-70-QRMG-304568</p><p
