端面比壓要合適，過大，將使機(jī)械密封摩擦面發(fā)熱，加速端面磨損，增加摩擦功率；過小，容易漏泄。端面比壓是在機(jī)械密封設(shè)計(jì)時(shí)確定的，我們在組裝時(shí)只能靠測量機(jī)械密封緊力來確定。通常情況的測量方法使測量安裝好的靜環(huán)端面至壓蓋端面的垂直距離，在測量動(dòng)環(huán)端面至壓蓋端面的垂直距離，兩者的差極為機(jī)械密封的緊力。4、測量補(bǔ)償彈簧的長度是否發(fā)生變化。彈簧性能的發(fā)生變化將會(huì)直接影響機(jī)械密封端面比壓。一般情況下彈簧在長時(shí)間運(yùn)行后長度會(huì)縮短，補(bǔ)償彈簧在動(dòng)環(huán)上的機(jī)械密封還會(huì)因?yàn)殡x心力的原因而變形。5、測量靜環(huán)防轉(zhuǎn)銷子的長度及銷孔深度，防止銷子過長靜環(huán)不能組裝到位。這種情況出現(xiàn)會(huì)損壞機(jī)械密封。二．多級離心泵機(jī)械密封的組裝經(jīng)過清掃檢查、技術(shù)尺寸校核后的機(jī)械密封即可回裝，在這個(gè)過程中要注意以下幾點(diǎn)：1、組裝時(shí)所有密封圈因該涂以肥皂水等潤滑劑，這樣可以避免組裝過程中損壞膠圈。動(dòng)靜環(huán)的密封面之間涂以潤滑脂，防止動(dòng)靜環(huán)密封面在水泵開車前磨損。2、浮動(dòng)環(huán)組裝時(shí)，一定要小心不要碰倒浮動(dòng)環(huán)彈簧，以免彈簧碰倒后影響浮動(dòng)環(huán)的浮動(dòng)性能。浮動(dòng)環(huán)組裝后，可以輕輕按浮動(dòng)環(huán)，以確定是否就有良好的浮動(dòng)性能。3、安裝密封時(shí)應(yīng)輕拿輕放，防止損壞密封件。</p><p> 在凝汽式火力發(fā)電廠中，凝汽器是汽輪發(fā)電機(jī)組的重要附屬設(shè)備之一，其作用之一是去除凝結(jié)水中的氧氣。汽輪發(fā)電機(jī)組凝結(jié)水溶氧超標(biāo)，將會(huì)腐蝕凝結(jié)水系統(tǒng)，由此產(chǎn)生的腐蝕產(chǎn)物在汽水系統(tǒng)中遷移，就會(huì)腐蝕機(jī)組的熱力設(shè)備，造成設(shè)備的結(jié)垢、積鹽，引起傳熱惡化，甚至引發(fā)爆管和主汽門卡澀，嚴(yán)重影響機(jī)組的安全經(jīng)濟(jì)運(yùn)行。因此，控制凝結(jié)水溶氧是火電廠的重要工作之一，對機(jī)組長期安全穩(wěn)定運(yùn)行具有非常重要的意義。下面我們從凝結(jié)水溶氧形成的原因及諸多影響因素著手，徹底查找一下火電廠凝結(jié)水溶氧超標(biāo)的原因。影響凝結(jié)水溶氧超標(biāo)的因素主要有以下幾點(diǎn)：1）凝汽器熱井凝結(jié)水存在過冷度的前提下，凝汽器中存在空氣，其中部分氧氣就可能溶解在凝結(jié)水中，使凝結(jié)水達(dá)不到飽和溫度，導(dǎo)致凝汽器真空除氧裝置除氧效果下降，造成溶氧升高。2）如果凝結(jié)水存在過冷卻現(xiàn)象，由于過冷度較大，凝結(jié)水溫度達(dá)不到對應(yīng)壓力下的飽和溫度，凝汽器大量補(bǔ)水時(shí)就有可能造成凝汽器熱井中的凝結(jié)水溶氧量升高。3）汽輪機(jī)機(jī)組負(fù)壓（冷端）系統(tǒng)（包括凝汽器汽側(cè)、排汽缸、6號至8號低加、軸封加熱器、軸加水封、軸封系統(tǒng)、高低加危急疏水管道放水門）泄漏。韶關(guān)神通博格曼機(jī)械密封。</p><div

另外還可選用[PV]值高的摩擦副材料，減小端面的接觸寬度，或者采用受控膜機(jī)械密封。近年來，一種名為差動(dòng)環(huán)式的機(jī)械密封也在高速設(shè)備中得到應(yīng)用。由于在原先的動(dòng)靜環(huán)中間加入了一個(gè)差動(dòng)環(huán)，可以將摩擦副線速度降低一半，取得了不錯(cuò)的效果。四、高壓下的機(jī)械密封機(jī)械密封工作壓力超過4-5MPa即屬于高壓密封范圍。在高壓條件下，由于密封端面比壓值過大，引起端面發(fā)熱，從而破壞液膜的形成，造成異常磨損。高壓還可能使摩擦副產(chǎn)生變形和破裂。高壓密封一般均采用平衡型結(jié)構(gòu)，以使端面比壓處于一個(gè)合適的范圍。但考慮到密封的可靠性，平衡系數(shù)不可能無限制增大，因而有些情況盡管已經(jīng)采用了平衡型結(jié)構(gòu)，但端面比壓仍可能較大。單靠平衡型結(jié)構(gòu)很難滿足使用要求，這種情況可采用多端面機(jī)封或者受控膜機(jī)械密封。五、腐蝕環(huán)境下的機(jī)械密封有些機(jī)械密封處于腐蝕環(huán)境中，這時(shí)不僅要注意機(jī)封中每個(gè)零件本身的耐腐蝕性，還要防止它們組合在一起時(shí)可能產(chǎn)生的電耦現(xiàn)象。腐蝕環(huán)境中的機(jī)械密封，在選用時(shí)要注意采用耐腐蝕的材料。此外，可以采用外裝式機(jī)械密封。對腐蝕性特強(qiáng)容易引起安全事故的，可以采用雙端面密封，引入隔離液加以保護(hù)。171神通博格曼機(jī)械密封。蘇州神通博格曼機(jī)械密封104</p><p
