</p> <p> 原因一、安裝過(guò)緊。觀察機(jī)械密封的動(dòng)靜環(huán)平面，如有嚴(yán)重?zé)宫F(xiàn)象，平面發(fā)黑和很深的痕跡，密封橡膠變硬，失去彈性，這種現(xiàn)象是由于安裝過(guò)緊造成的。 </p> <p> 處理辦法：調(diào)整安裝高度，葉輪發(fā)裝后，用螺絲刀拔動(dòng)彈簧，彈簧有較強(qiáng)的張力，松開(kāi)后即復(fù)λ，有24MM的移動(dòng)距離即可。 </p> <p> 原因二、安裝過(guò)松。觀察機(jī)封動(dòng)、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無(wú)磨損，這是彈簧失去彈性及裝配不良造成，或電機(jī)軸向竄動(dòng)造成。 </p> <p> 原因三、水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機(jī)封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。 </p> <p> 處理辦法：改進(jìn)水壓或介質(zhì)，更換機(jī)封。 </p> <p> 原因四、缺水運(yùn)行造成干磨損壞。此現(xiàn)象多見(jiàn)于底閥式安裝形式進(jìn)口處負(fù)壓，進(jìn)水管有空氣，泵腔內(nèi)有空氣，泵開(kāi)機(jī)后，機(jī)封的磨擦高速運(yùn)轉(zhuǎn)時(shí)產(chǎn)生高溫，無(wú)法得到冷卻，檢查機(jī)封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開(kāi)裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機(jī)械密封。淮安化工泵密封廠在實(shí)際安裝過(guò)程中，應(yīng)該做好對(duì)裝配圖的核對(duì)工作，并檢各種零件表面是否出現(xiàn)了劃痕、缺點(diǎn)等情況。</p><div

設(shè)備轉(zhuǎn)軸的勁向跳動(dòng)應(yīng)≤0.04毫米，軸向竄動(dòng)量不允許大于0.1毫米； </p> <p> 安裝靜環(huán)壓蓋時(shí)，擰緊螺絲必須受力均勻，保證靜環(huán)端面與軸垂直求； </p> <p> 安裝后用手推動(dòng)動(dòng)環(huán)，能使動(dòng)環(huán)在軸上靈活移動(dòng)，并有一定彈性； </p> <p> 安裝后用手盤動(dòng)轉(zhuǎn)軸、轉(zhuǎn)軸應(yīng)無(wú)輕重感覺(jué)； </p> <p> 設(shè)備在運(yùn)轉(zhuǎn)前必須充滿介質(zhì)，以防止干摩擦而使密封失效； </p> <p> <br /> </p><p> 為了使密封面之間始終保持互相配合，彈簧起到了機(jī)械密封與運(yùn)動(dòng)主軸之間的恒定調(diào)節(jié)作用。當(dāng)旋轉(zhuǎn)面和主軸之間采用人造橡膠密封時(shí)，該彈性體就會(huì)在主軸上來(lái)回運(yùn)動(dòng)。這種重復(fù)摩擦動(dòng)作，會(huì)磨蝕主軸上的防腐材料，失去主軸的氧化膜保護(hù)層，**終會(huì)在主軸的摩擦面上形成磨損溝槽，造成液體從溝槽中泄漏，并增加必要的維修工作量或甚至更換主軸。為了解決這一問(wèn)題，一般在填料盒內(nèi)安裝一個(gè)可更換的軸套。 </p> <p> 然而，解決腐蝕磨損問(wèn)題的長(zhǎng)久辦法是去除其內(nèi)部的動(dòng)態(tài)密封。現(xiàn)在，大部分主要密封制造廠生產(chǎn)非腐蝕磨損型密封，以防止液泵零件的腐蝕磨損。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(guò)大等,都會(huì)縮短機(jī)械密封的使用壽命。</p><div

墊片密封機(jī)理： </p> <p> 泄漏即介質(zhì)從有限空間內(nèi)部流到外部，或從外部進(jìn)入有限空間內(nèi)部的人們不希望發(fā)生的現(xiàn)象 ,介質(zhì)流動(dòng)通過(guò)內(nèi)外空間的交界面即密封面發(fā)生泄漏。造成泄漏的根本原因是由于接觸面上存在間隙，而接觸面兩側(cè)的壓力差、濃度差則是泄漏的推動(dòng)力。由于密封面形式及加工精度等因素的影響，密封面上存在間隙在所難免，這就會(huì)造成密封面不完全吻合，從而發(fā)生泄漏。要減少泄漏，就必須使接觸面很大程度地嵌合，即減小泄漏通道的截面積，增加泄漏阻力，并使之大于泄漏推動(dòng)力。 </p> <p> 對(duì)密封面施加壓緊載荷，以產(chǎn)生壓緊應(yīng) 力，可提高密封面的接觸程度，當(dāng)應(yīng)力增大到足以引起表面產(chǎn)生明顯的塑性變形時(shí)，就可以填補(bǔ)密封面的間隙，堵塞泄漏通道。使用墊片的目的就是利用墊片材料在壓緊載荷的作用下較容易產(chǎn)生塑性變形的特性，使之填平法蘭密封面的微小凹凸不平，從而實(shí)現(xiàn)密封。根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。江蘇電動(dòng)泵密封批發(fā)價(jià)</p><p
