機(jī)械密封是利用兩個(gè)平面互相摩擦運(yùn)行的原理，達(dá)到密封的目的。旋轉(zhuǎn)密封面安裝于液泵的主軸上，而固定密封面安裝于密封壓蓋內(nèi)。由于一個(gè)密封面是運(yùn)動(dòng)的，而另一個(gè)密封面是靜止不動(dòng)的，因此將這類(lèi)密封稱之為動(dòng)態(tài)密封。旋轉(zhuǎn)面與靜止面之間的密封是決定密封性能關(guān)鍵的因素。基礎(chǔ)的機(jī)械密封如圖1所示，其中有4個(gè)泄漏通路需要密封：1.密封面之間的通路;2.旋轉(zhuǎn)面與主軸之間的通路;3.固定面與壓蓋之間的通路;4.壓蓋與填料盒之間的通路。后兩種泄漏通路一般采用靜態(tài)密封，因?yàn)閮刹糠种g不存在相對(duì)運(yùn)動(dòng)。這部分的密封通常都稱之為三次密封，其密封材料為墊片或與工藝流程液體相適應(yīng)的O型密封圈。在較老的密封設(shè)計(jì)中，位于旋轉(zhuǎn)面下的二次密封留有一定的間隙，可在主軸上前后運(yùn)動(dòng)，因此易于引起磨損和過(guò)早失效。然而在較新的密封設(shè)計(jì)中，二次密封處于靜止?fàn)顟B(tài)，因此可避免在主軸上出現(xiàn)磨損腐蝕問(wèn)題。在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動(dòng)和停機(jī)時(shí)，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來(lái)代替)。大部分機(jī)械密封的設(shè)計(jì)采用較軟的材料來(lái)制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來(lái)。</p><p> 改善了追隨性;對(duì)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(dòng)沒(méi)有阻力，使用扭矩的傳遞不影響波紋管，能起到補(bǔ)償作用，適用于高溫、高速、高粘度、高腐蝕等各類(lèi)的工況。故金屬波紋管機(jī)械密封在煉**業(yè)的離心泵上得到應(yīng)用。金屬波紋管機(jī)械密封實(shí)物圖金屬波紋管機(jī)械密封優(yōu)點(diǎn)：具有高精密性：焊接波紋管起到彈簧的作用，而且是好多個(gè)彈簧的組合體，所以解決了普通彈簧因離心力變形的問(wèn)題，適應(yīng)高度旋轉(zhuǎn)，并且使密封面受壓均勻，利于防止泄露。具有耐振動(dòng)和柔韌性：波紋管柔韌性高，對(duì)振動(dòng)的吸收效果非常好，所以對(duì)徑向跳動(dòng)、軸向間隙、振動(dòng)和擺動(dòng)的適應(yīng)能力非常強(qiáng)，能有效阻止泄露。結(jié)構(gòu)簡(jiǎn)單：不像其他普通機(jī)械密封要由很多零件組成，具有整合組裝、構(gòu)造簡(jiǎn)單、容易裝配的特點(diǎn)能適應(yīng)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(méi)有O型圈，擺脫溫度的限制條件，設(shè)計(jì)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(shè)計(jì)相應(yīng)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。無(wú)軸套有效保護(hù)機(jī)泵：焊接波紋管機(jī)械密封因沒(méi)有O型環(huán)，不需要安裝軸套。亳州橡膠波紋管機(jī)械密封件。</p><div

多級(jí)離心泵機(jī)械密封問(wèn)題解析1、沒(méi)有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)置不合理多級(jí)離心泵機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效地保護(hù)密封面，起到冷卻、潤(rùn)滑、沖走雜物等作用。有時(shí)設(shè)計(jì)員沒(méi)有合理地配置輔助沖洗系統(tǒng)，達(dá)不到密封效果；有時(shí)雖然設(shè)計(jì)人員設(shè)計(jì)了輔助系統(tǒng)，但由于沖洗液中有雜質(zhì)，沖洗液的流量、壓力不夠，沖洗口位置設(shè)計(jì)不合理等原因，也同樣達(dá)不到密封效果。2、振動(dòng)偏大機(jī)械密封振動(dòng)偏大，**終導(dǎo)致失去密封效果。但機(jī)械密封振動(dòng)偏大的原因往往不是機(jī)械密封本身的原因，多級(jí)離心泵的其它零部件是產(chǎn)生振動(dòng)的根源，如多級(jí)離心泵泵軸設(shè)計(jì)不合理、加工的原因、軸承精度不夠、聯(lián)軸器的平行度差、徑向力大等原因。3、多級(jí)離心泵汽蝕的原因由于裝置系統(tǒng)操作不合理以及工業(yè)多級(jí)鍋爐給水泵進(jìn)口汽蝕性能不好、泵的轉(zhuǎn)速偏高，在泵的入口處發(fā)生局部汽蝕，汽蝕發(fā)生后，水中會(huì)有氣泡，它一方面會(huì)沖擊機(jī)械密封面的外表面，使其表面出現(xiàn)破損；另一方面會(huì)使動(dòng)靜環(huán)的吻合面的流動(dòng)膜中也含有氣泡，不能形成穩(wěn)定的流動(dòng)膜，造成動(dòng)靜環(huán)的吻合面的干摩擦，使機(jī)械密封裝置損壞。4、機(jī)械加工精度不夠機(jī)械加工精度不夠，原因有很多，有的是機(jī)械密封本身的加工精度不夠。南通輕型機(jī)械密封件。FA1D63機(jī)械密封</p><p

沖洗液可以是熱水或蒸汽。九、機(jī)械密封典型失效原因分析（一）機(jī)械密封本身問(wèn)題1、鑲裝不到位或不平整。2、載荷系數(shù)太大或端面比壓設(shè)計(jì)不合理。3、材質(zhì)選用不當(dāng)。4、密封面不平。5、密封面太寬或太窄。（二）輔助系統(tǒng)問(wèn)題1、工況條件復(fù)雜，但沒(méi)有沖洗等輔助設(shè)施。2、沖洗管堵塞。3、冷卻管結(jié)垢。（三）介質(zhì)及工作條件問(wèn)題1、介質(zhì)腐蝕性強(qiáng)。2、介質(zhì)中有固體顆粒。3、設(shè)備抽空。4、密封面結(jié)晶。5、介質(zhì)粘度太大。（四）泵的問(wèn)題1、軸的加工精度不佳、串軸、跳動(dòng)、安裝間隙過(guò)大。2、泵開(kāi)啟后振動(dòng)太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機(jī)械密封安裝沒(méi)有達(dá)到應(yīng)有的壓縮量。十、常見(jiàn)的滲漏現(xiàn)象機(jī)械密封滲漏的比例占全部維修泵的50%以上，機(jī)械密封的運(yùn)行好壞直接影響到水泵的正常運(yùn)行，現(xiàn)總結(jié)分析如下：1、周期性滲漏（1）泵轉(zhuǎn)子軸向竄動(dòng)量大，輔助密封與軸的過(guò)盈量大，動(dòng)環(huán)不能在軸上靈活移動(dòng)。在泵翻轉(zhuǎn)，動(dòng)、靜環(huán)磨損后，得不到補(bǔ)償位移。對(duì)策：在裝配機(jī)械密封時(shí)，軸的軸向竄動(dòng)量應(yīng)小于0．1mm，輔助密封與軸的過(guò)盈量應(yīng)適中，在保證徑向密封的同時(shí)，動(dòng)環(huán)裝配后保證能在軸上靈活移動(dòng)（把動(dòng)環(huán)壓向彈簧能自由地彈回來(lái)）。（2）密封面潤(rùn)滑油量不足引起干摩擦或拉毛密封端面。機(jī)械密封KCC40-25-250</p><p
