機械密封是離心泵的主要易損件之一，因而泵的故障多數(shù)是由密封失效所導(dǎo)致的。據(jù)統(tǒng)計，機械密封失效導(dǎo)致泵的故障占設(shè)備故障率的50%以上，所以有必要對離心泵的機械密封泄漏進行分析改進，以降低泵的故障率。一、離心泵工作原理及機械密封裝置的作用離心泵通過電機、聯(lián)軸器，使其葉輪高速旋轉(zhuǎn)，在葉片之間的液體受到葉片的推動，在離心力的作用下，不斷地從中心被甩向四周，當(dāng)泵內(nèi)液體從葉輪中心被拋向邊緣時，中心處形成了低壓區(qū)，由于進泵前的液體壓強大于泵吸入口處的壓強，在壓強差的作用下，液體便經(jīng)吸入管連續(xù)地吸入泵內(nèi)，以補充被排出液體的位置，只要葉輪不停地旋轉(zhuǎn)，液體便不斷地吸入和排出。泵軸穿過泵殼時，動靜之間有間隙存在時，泵內(nèi)的液體就會從間隙漏至泵外，若吸入端是真空，則外界空氣會漏入泵內(nèi)，嚴(yán)重影響泵的工作，為了減少泄漏，一般在動靜間隙處裝有軸端密封裝置。軸封裝置是離心泵的重要部件，它直接關(guān)系到離心泵能否正常工作。現(xiàn)在軸封裝置一般采用機械密封。二、機械密封原理機械密封是一種依靠彈性元件對動、靜環(huán)端面密封副的預(yù)緊和介質(zhì)壓力與彈性元件壓力的壓緊而達到密封的軸向端面密封裝置。機械密封通常由靜環(huán)、動環(huán)、壓緊元件和密封元件組成。晉城格蘭富機械密封件CR64-2-1茂名格蘭富機械密封件。</p><div

但這種做法要求在密封維修時將液泵的濕端拆卸下來，其主要好處是密封的環(huán)境衛(wèi)生易于控制。外密封的安裝方式是將靜態(tài)密封面的方向顛倒過來，主軸上的旋轉(zhuǎn)單元位于填料盒壓蓋的外面。外密封主要具有以下五大好處：1.安裝容易;2.費用相對較低;3.可以連續(xù)監(jiān)控和清潔;4.適于無法在內(nèi)部安裝密封的很小填料盒;5.由于其位置接近軸承，對主軸偏差的困難影響較少。其主要缺點是離心力會將固體顆粒從密封的下面甩向密封的接觸面上。因此，這類密封主要適用于清潔且不含有磨料的液體。近年來，分離式密封已成為外密封中的另一重要附加特性。分離式密封是一個成套總成，安裝于填料盒與軸承套之間，采用這種設(shè)計，在密封需要更換時，不需要每次都拆卸液泵。這類密封結(jié)合探討其他設(shè)計標(biāo)準(zhǔn)正在逐步開發(fā)之中。由于這種設(shè)計易于更換密封，因此應(yīng)**只更換密封件的這種誘惑，而對出現(xiàn)故障的根源不做進一步的調(diào)查，這一點非常重要。彈筒式密封圖4自身帶有全部功能的彈筒式密封裝置采用這種密封可簡化安裝程序，同時可保護內(nèi)部各個元件，免受意外損壞。彈筒式密封是一種集全部功能于一身的密封裝置，其內(nèi)部包括所有的密封元件、壓蓋和軸套(見圖4)。由于這類密封不需要任何嚴(yán)格的安裝措施。</p><p> 而且還會使得動環(huán)軸向的調(diào)整以及移動的阻力增加，在化工泵的工作過程中，當(dāng)泵的運行速度增加后，就無法進行適時的調(diào)節(jié);另一方面，過緊還會造成化工泵彈簧出現(xiàn)過度的疲勞，長期處于超負(fù)荷工作狀態(tài)中的彈簧其使用時間就會縮短，進而導(dǎo)致密封的失效。靜環(huán)密封圈泵的靜環(huán)密封圈一般情況下處于靜止?fàn)顟B(tài)，因此，適當(dāng)增加其張緊程度能夠在一定程度上密封，但是不容忽視的是，靜環(huán)密封圈過緊對化工泵的機械密封也存在著不利的影響。首先，長期處于過緊狀態(tài)中的靜環(huán)密封圈會發(fā)生一定程度的塑性變形，進而對其密封性能帶來不利的影響;其次，靜環(huán)密封圈大都采用石墨制作而成，由于材料的性質(zhì)，造成其質(zhì)脆易碎，當(dāng)其受力過度時極易發(fā)生破碎，而且靜環(huán)密封圈過緊會造成安裝，拆卸等操作的不便，從而使得靜環(huán)密封圈容易發(fā)生損壞。主要是以下幾個：端面間的磨損加劇就產(chǎn)生液膜汽化失穩(wěn)這降低密封件的使用壽命產(chǎn)生密封環(huán)間形成較大的溫度梯度是因為密封環(huán)間的導(dǎo)熱不均，從而產(chǎn)生熱變形，較大的熱變形使接觸面形成錐形表面。黑河格蘭富機械密封件。</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。邯鄲格蘭富機械密封件。晉城格蘭富機械密封件CR64-2-1</p><p

柔性石墨填料等用于離心泵的軟填料，它們的性能好，適應(yīng)的范圍也廣，值得應(yīng)用。其三是散熱，冷卻能力的設(shè)計：例如圖中的圖結(jié)構(gòu)就存在散熱，冷卻能力不足的問題，即便是圖中的圖結(jié)構(gòu)，由于水環(huán)的存水量太小，冷卻能力還是受限的，而圖中的圖結(jié)構(gòu)就比較完美地解決了散熱與冷卻能力的設(shè)計問題。電站閥常用的自密封結(jié)構(gòu)有楔形墊組合密封應(yīng)力松弛造成密封工作穩(wěn)定性差泵用軟填料密封結(jié)構(gòu)中的軟填料在軸向壓緊調(diào)節(jié)裝置的作用下，內(nèi)部將產(chǎn)生軸向和徑向應(yīng)力，當(dāng)然，周向同樣會產(chǎn)生應(yīng)力。隨著泵的長期工作，軟填料不斷在磨耗，若不及時調(diào)節(jié)，其將產(chǎn)生所謂“應(yīng)力松弛”。一旦產(chǎn)生應(yīng)力松弛，密封就會受到影響，將致使密封工作穩(wěn)定性變差。軟填料自動補償能力問題既然軟填料在工作中與軸形成滑動摩擦，其磨損是較大的，磨損后填料與軸桿，填料箱內(nèi)壁之間的間隙加大，如果沒有自動補償機構(gòu)，則隨著軟填料的磨損，泄漏量將逐漸增大。但未達到流淌程度成批生產(chǎn)某種幾何形狀的密封墊片時，應(yīng)利用模具沖壓；批量少的可用法蘭密封面涂顏料貼印的方法進行剪裁制造。結(jié)構(gòu)設(shè)計的合理與優(yōu)化①改進密封結(jié)構(gòu)，在填料環(huán)之間加入自動補償機構(gòu)。填料沿填料長度涵方向的徑向應(yīng)力分布不均勻。晉城格蘭富機械密封件CR64-2-1</p><p
