例如旋轉式和靜止式機械密封；內流式和外流式機械密封；平衡型和非平衡型機械密封等。按補償機構彈性元件的運動狀況，可分為旋轉式和靜止式機械密封。補償機構隨軸旋轉的稱為旋轉式機械密封（圖2）；補償機構不旋轉的（安裝在壓蓋內）稱為靜止式機械密封（圖3）。補償機構旋轉時易產生質量不平衡，同時消耗攪拌功率，因此，旋轉式密封不能用于高速；而靜止式密封可用于高速。但是旋轉式密封安裝較方便，所以，普通的機械密封大多采用旋轉式結構。按靜環(huán)的安裝位置可分為內裝式和外裝式機械密封。靜環(huán)裝于密封壓蓋（或相當于密封壓蓋的零件）內側（即面向主機工作腔側）的機械密封稱為內裝式機械密封（如圖1）；反之，在密封壓蓋的外側安裝靜環(huán)時稱為外裝式機械密封（圖4）。內裝式機械密封可用于溫度和壓力較高，鄂爾多斯M481釜用機械密封件維修，鄂爾多斯M481釜用機械密封件維修，以及介質對動環(huán)及彈性元件的腐蝕性不高的工況。外裝式機械密封適用于低壓（或負壓）和介質具有腐蝕性的工況，鄂爾多斯M481釜用機械密封件維修。(圖4)密封流體在密封端面間的泄漏方向和離心力方向相反的機械密封稱為內流型機械密封；密封流體在密封端面間的泄漏方向與離心力方向相同時稱為外流型機械密封。一般情況下，內流型機械密封多出現(xiàn)在內裝式機械密封中（如圖1、2、3）。三門峽M461釜用機械密封件。鄂爾多斯M481釜用機械密封件維修</p><div

中間沒有輔助密封圈，因此減少了一個泄漏點;同時減少了補償機構的摩擦阻力，改善了追隨性;對于焊接金屬波紋管密封使用溫度不受輔助密封圈的限制。波紋管具有一定的彈性且移動沒有阻力，使用扭矩的傳遞不影響波紋管，能起到補償作用，適用于高溫、高速、高粘度、高腐蝕等各類的工況。故金屬波紋管機械密封在煉**業(yè)的離心泵上得到***的應用。金屬波紋管機械密封實物圖金屬波紋管機械密封優(yōu)點：具有高精密性：焊接波紋管起到彈簧的作用，而且是好多個彈簧的組合體，所以解決了普通彈簧因離心力變形的問題，適應高度旋轉，并且使密封面受壓均勻，利于防止泄露。具有耐振動與柔韌性：波紋管柔韌性高，對振動的吸收效果非常好，所以對徑向跳動、軸向間隙、振動和擺動的適應能力非常強，能有效阻止泄露。結構簡單：不像其他普通機械密封要由很多零件組成，具有整合組裝、構造簡單、容易裝配的特點能適應多種溫度條件的工況：焊接波紋管的熱膨脹系數(shù)小，可在低溫或高溫的下使用，而且沒有O型圈，擺脫溫度的限制條件，設計比較自由。適用于高壓工況：由于波紋管本身能起平衡作用，可設計相應的密封面積抵消流體壓力，減少密封面的摩擦，從而減少發(fā)熱以及磨損量，可用于高壓工況。津南區(qū)2009釜用機械密封件廠家懷化M481釜用機械密封件。</p><div

由兩組動環(huán)和靜環(huán)采用背靠背的方式安裝。圖1機械密封結構2、機械密封失效原因分析轉動設備故障中，因機械密封泄漏而停機檢修的約占設備維修總量的50%左右。攪拌器使用的機械密封為雙端面機械密封，雙端面機械密封失效機理與單端面機械密封失效機理基本相同，主要是密封面的失效。在設備運行過程中，由于摩擦和攪拌產生的熱量會使密封面溫度升高，加之介質的影響，就會出現(xiàn)密封面介質的氣化、密封環(huán)變形、熱磨損，甚至出現(xiàn)熱裂。有的介質在溫度變化時會加劇固化、聚合、結晶、結焦和腐蝕。種種非正常的工況將加劇或者短期內直接導致密封失效。機封失效的原因是多方面的，一方面是機封本身存在缺陷造成的，另一方面是外部因素影響機封的正常運行造成的，結合實際生產中遇到的問題，經(jīng)過分析可能有以下幾個原因：（1）端面不平，即端面平面度、粗糙度未達到要求，或在使用前受到了損傷；（2）輔助密封圈的故障：裝配性的故障有掉塊、裂口、碰傷、卷邊和扭曲；非裝配性的故障有變形、硬化、破裂和變質；（3）機械密封的端面比壓是影響密封性能和使用壽命的重要因素【2】；（4）密封面溫度升高，導致動靜環(huán)變形甚至破損【3】；（5）機封沖洗中斷或壓力、流量不滿足使用要求；。</p><p> 人們在分析機械封泄漏原因時，習慣在機械封自身方面查找原因，比如：它的選型是否合適，材料選擇是否正確，密封面的比壓是否正確。摩擦副的選擇是否合理，端蓋與軸是否垂直等等，而很少在機械密封的外部條件方面去查找原因，其實機械密封的外因也挺重要的，比如：泵給機械密封創(chuàng)造的條件是否合適，輔助系統(tǒng)的配置是否合適等。一、機械密封的原理及要求機械密封系指兩塊密封元件在其垂直于軸線的光潔而平直的表面上相互貼合，并作相對轉動而構成的密封裝置，他通常由靜環(huán)、動環(huán)、彈簧加荷裝置（包括推環(huán)，彈簧盒）輔助密封圈（動環(huán)密封圈、靜環(huán)密封圈）等元件組成，防轉套里面的防轉銷固定在外壓蓋上，以防止靜環(huán)轉動。其中動環(huán)和靜環(huán)的端面組成一對摩擦副，動環(huán)靠密封室內液體的壓力使其端面壓緊在靜環(huán)端面上，并在兩環(huán)端面上產生適當?shù)谋葔汉捅３忠粚訕O薄的液體膜而達到密封的，因此從結構來看，機械密封主要是將其極易泄漏的軸向密封，改變?yōu)椴灰仔孤┑亩嗣婷芊猓瑱C械密封在實際運行過程中，不是一個單獨的部件，它是與其他的零部件一起組合起來運行的，同時通過其基本原理可以看出，機械密封的正常運行必須具備以下條件：（1）泵軸的竄量不能太大；。黃岡MR-D釜用機械密封件。</p><div
