避免造成O型圈侵油膨脹或加速老化，造成密封提前失效。5三個(gè)密封點(diǎn)及其密封原理動(dòng)環(huán)與靜環(huán)之間的密封：是靠彈性元件(彈簧、波紋管等)和密封液體壓力在相對(duì)運(yùn)動(dòng)的動(dòng)環(huán)和靜環(huán)的接觸面(端面)上產(chǎn)生一適當(dāng)?shù)膲壕o力(比壓)使兩個(gè)光潔、平直的端面緊密貼合;端面間維持一層極薄的液體膜而達(dá)到密封的作用。這層膜具有液體動(dòng)壓力與靜壓力，它起著平衡壓力和潤(rùn)滑端面的作用。兩端面之所以必需高度光潔平直是為了給端面創(chuàng)造完美貼合和使比壓平均的前提，這是相對(duì)旋轉(zhuǎn)密封。6機(jī)械密封技術(shù)的種類當(dāng)前采用新材料和工藝的各種機(jī)械密封的新技術(shù)，進(jìn)展較快，有下列的機(jī)械密封新技術(shù)。密封面開(kāi)槽密封技術(shù)近年來(lái)，在機(jī)械密封的密封端面上開(kāi)了各種各樣的流槽，以產(chǎn)生流體靜、動(dòng)壓效應(yīng)，現(xiàn)在還在不斷更新。零泄漏密封技術(shù)過(guò)去總以為接觸式和非接觸式機(jī)械密封不可能達(dá)到零泄漏(或無(wú)泄漏)。以色列利用開(kāi)槽密封技術(shù)，提出零泄漏非接觸式機(jī)械端面密封的新概念，并已用于核電站潤(rùn)滑油泵中。干運(yùn)轉(zhuǎn)氣體密封技術(shù)這類密封是將開(kāi)槽密封技術(shù)用于氣體密封。上游泵送密封技術(shù)即利用密封面上開(kāi)流槽將下游少量泄漏流體泵送回上游。上述幾類密封的結(jié)構(gòu)特點(diǎn)是：采用淺槽，且膜厚和流槽的深均屬微米級(jí)。</p><p> 以及雜質(zhì)堆積和結(jié)焦等，可采用切向引入或多點(diǎn)沖洗.必要時(shí)，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)。常熟YM109機(jī)械密封件。</p><div
