新技術(shù)不斷出現(xiàn)給我們維修帶來了新的課題。(2)結(jié)構(gòu)復(fù)雜、拆裝不便。與其它密封比較，機(jī)械端面密封的零件數(shù)目多，要求精密，結(jié)構(gòu)復(fù)雜。特別是在裝配方面較困難，長(zhǎng)春凱士比機(jī)械密封ETB080065-200，拆裝時(shí)要從軸端抽出密封環(huán)，必須把機(jī)器部分(聯(lián)軸器)或全部拆卸。這一問題目前已作了某些改進(jìn)，例如采用拆裝方便并可保證裝配質(zhì)量的剖分式和集裝式機(jī)械密封等。機(jī)械密封實(shí)現(xiàn)的原理及結(jié)構(gòu)圖機(jī)械密封原理如圖所示：圖一：機(jī)械密封1、靜環(huán)2、動(dòng)環(huán)3、動(dòng)環(huán)密封面4、推環(huán)5、彈簧6，長(zhǎng)春凱士比機(jī)械密封ETB080065-200、傳動(dòng)座7、靜環(huán)密封面8、壓蓋9、墊片軸通過傳動(dòng)座（6）和推環(huán)（4），帶動(dòng)動(dòng)環(huán)（2）旋轉(zhuǎn)，靜環(huán)(1)固定不動(dòng)，依靠介質(zhì)壓力和彈簧力使動(dòng)靜環(huán)之間的密封端面緊密貼合，阻止了介質(zhì)的泄漏，長(zhǎng)春凱士比機(jī)械密封ETB080065-200。摩擦副表面磨損后，在彈簧（5）的推動(dòng)下實(shí)現(xiàn)補(bǔ)償。為了防止介質(zhì)通過動(dòng)環(huán)與軸之間泄漏，裝有動(dòng)環(huán)密封圈（3）；而靜環(huán)密封圈（7）則阻止了介質(zhì)沿靜環(huán)和壓蓋（8）之間的泄漏。按補(bǔ)償機(jī)構(gòu)彈性元件的運(yùn)動(dòng)狀況，可分為旋轉(zhuǎn)式和靜止式機(jī)械密封。補(bǔ)償機(jī)構(gòu)隨軸旋轉(zhuǎn)的稱為旋轉(zhuǎn)式機(jī)械密封（圖2）；補(bǔ)償機(jī)構(gòu)不旋轉(zhuǎn)的（安裝在壓蓋內(nèi)）稱為靜止式機(jī)械密封（圖3）。補(bǔ)償機(jī)構(gòu)旋轉(zhuǎn)時(shí)易產(chǎn)生質(zhì)量不平衡，同時(shí)消耗攪拌功率，因此，旋轉(zhuǎn)式密封不能用于高速。內(nèi)蒙古凱士比機(jī)械密封廠。長(zhǎng)春凱士比機(jī)械密封ETB080065-200</p><div

產(chǎn)生阻力，阻止介質(zhì)泄漏，同時(shí)液膜也起到潤(rùn)滑和冷卻的作用，使機(jī)械密封的壽命增長(zhǎng)。為了保證密封端面間必需的液膜，必須嚴(yán)格控制端面上的壓力，若壓力過大，則不易形成穩(wěn)定的潤(rùn)滑液膜，從而導(dǎo)致端面的快速磨損；若壓力過小，則影響密封效果導(dǎo)致泄漏量增加。機(jī)械密封沖洗方案及其特點(diǎn)機(jī)械密封的沖洗是一種控制機(jī)械密封溫度、延長(zhǎng)機(jī)械密封壽命的有效措施。沖洗的目的在于帶走熱量、保持和改善潤(rùn)滑、防止液膜氣化、防止雜質(zhì)集積、防止氣囊形成等。根據(jù)沖洗形式可分為內(nèi)沖洗和外沖洗，其中內(nèi)沖洗時(shí)利用輸送介質(zhì)進(jìn)行沖洗，而外沖洗則是通過引入外界物質(zhì)進(jìn)行沖洗。（1）內(nèi)沖洗正沖洗工作原理：由泵的出口端通過管路引被密封介質(zhì)入密封腔。實(shí)用范圍：用于清潔介質(zhì)，p1稍大于p進(jìn)，若介質(zhì)溫度高或有雜質(zhì)，則需在管路上設(shè)置冷卻器、過濾器等設(shè)備對(duì)介質(zhì)進(jìn)行處理。反沖洗工作原理：利用工作主機(jī)的被密封介質(zhì)，由泵的出口端引入密封腔，沖洗后通過管路流回泵入口。實(shí)用范圍：用于清潔介質(zhì)，且p進(jìn)機(jī)械密封安裝（1）、安裝前首先要檢查機(jī)械密封各部件是齊全、完好，有無(wú)裂痕和缺失。（2）、檢查旋轉(zhuǎn)環(huán)和靜止環(huán)密封端面是否平整，有無(wú)劃痕，有無(wú)雜質(zhì)，有無(wú)銹蝕，端面間隙是否一致。。韶關(guān)凱士比機(jī)械密封HPKS125315-013凱士比機(jī)械密封RPK100-400。</p><div

機(jī)械密封組成（1）由旋轉(zhuǎn)環(huán)和靜止環(huán)組成的密封端面，又稱摩擦副。（2）由彈簧元件組成的補(bǔ)償機(jī)構(gòu)。（3）輔助密封圈，包括動(dòng)環(huán)密封圈和靜環(huán)密封圈。（4）使旋轉(zhuǎn)環(huán)隨軸一起旋轉(zhuǎn)的傳動(dòng)元件。機(jī)械密封的密封實(shí)現(xiàn)形式軸帶動(dòng)旋轉(zhuǎn)環(huán)轉(zhuǎn)動(dòng)，靜止環(huán)固定在壓蓋上。兩者間的密封面通過介質(zhì)壓力和補(bǔ)償機(jī)構(gòu)緊密結(jié)合，達(dá)到防止介質(zhì)泄露和空氣滲入的目的。為了防止介質(zhì)通過旋轉(zhuǎn)環(huán)和軸之間泄露出來，故安裝動(dòng)環(huán)密封圈，而靜環(huán)密封圈則阻止了介質(zhì)通過靜止環(huán)與壓蓋之間泄露的可能。靜止環(huán)與壓蓋、壓蓋與殼體之間的密封，二者均屬靜密封。當(dāng)端面摩擦磨損后，旋轉(zhuǎn)環(huán)*能沿軸向作微量的移動(dòng)，因此旋轉(zhuǎn)環(huán)與軸之間的密封實(shí)際上也是一個(gè)靜密封。這些泄漏通道比較容易封堵。靜密封元件常用的有橡膠O形圈或聚四氟乙烯V形圈，而作為補(bǔ)償環(huán)的旋轉(zhuǎn)環(huán)或靜止環(huán)輔助密封，則采用兼?zhèn)鋸椥栽δ艿南鹉z、聚四氟乙烯或金屬波紋管的結(jié)構(gòu)。旋轉(zhuǎn)環(huán)與靜止環(huán)的端面則是做著相當(dāng)運(yùn)動(dòng)的動(dòng)密封。因此它是整個(gè)機(jī)械密封裝置中的主密封，同時(shí)也決定密封效果和機(jī)械密封的壽命。機(jī)械密封在工作過程中，由于旋轉(zhuǎn)環(huán)和靜止環(huán)兩個(gè)密封端面緊密配合，使密封端面之間形成一道微小間隙，當(dāng)介質(zhì)通過此間隙時(shí)，形成極薄的液膜。長(zhǎng)春凱士比機(jī)械密封ETB080065-200</p></p><br
