其余安裝及外型尺寸不受影響。副葉片和固定導(dǎo)葉加工難度較大，一般離心泵上沒有，在改造時可根據(jù)情況決定是否采用。在低于50m揚(yáng)程的泵也可不采用副葉片和固定導(dǎo)葉，只采用副葉輪。3、動力密封裝置整體工作原理在運(yùn)轉(zhuǎn)時，離心泵工作葉輪與起密封作用的副葉輪同軸旋轉(zhuǎn)，工作葉輪泄漏出來的液體流到副葉輪后，通過副葉輪作用產(chǎn)生的壓力，與泄漏液體的壓力在副葉輪頂端與密封總成內(nèi)端面處達(dá)到平衡，從而使泄漏液體起到密封作用。在停車時，副葉輪動力密封不起作用，泵內(nèi)液體壓力較小，泄漏到副葉輪的液體通過油封進(jìn)行密封。4、副葉輪動力密封設(shè)計應(yīng)注意的問題（1）離心泵采用副葉輪密封無需考慮冷卻措施，若用于氣體密封，則需設(shè)置旁通回路從外部引入封液進(jìn)行冷卻。（2）副葉輪密封消耗的附加功率與其外徑的五次方成正比，因此一般不采用外徑過大的方案，而應(yīng)該同時設(shè)副葉片和副葉輪，以便減小外徑，減少功耗。（3）副葉輪動力密封及停車密封裝置材料的選擇要根據(jù)使用介質(zhì)的要求來決定，否則要影響使用壽命，特別是停車密封還要考慮冷卻和潤滑等。（4）因為副葉輪葉片的進(jìn)口角同副葉輪的密封能力無關(guān)，所以葉片形狀可以用徑向直葉片以便加工制造。太原襄樊五二五機(jī)械密封IH-35S300襄樊五二五機(jī)械密封HTM-60S310。</p><div

1.彈簧壓縮量越大密封效果越好？其實(shí)不然，彈簧壓縮量過大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損；過度的壓縮使彈簧失去調(diào)節(jié)動環(huán)端面的能力，導(dǎo)致密封失效。2.動環(huán)密封圖越緊越好？其實(shí)動環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，泄漏；二是增大了動環(huán)軸向調(diào)整、移動的阻力，在工況變化頻繁時無法適時進(jìn)行調(diào)整；三是彈簧過度疲勞易損壞；四是使動環(huán)密封圈變形，影響密封效果。3．靜環(huán)密封圈越緊越好？靜環(huán)密封圈基本處于靜止?fàn)顟B(tài)，相對較緊密封效果會好些，但過緊也是有害的。一是引起靜環(huán)密封因過度變形，影響密封效果；二是靜環(huán)材質(zhì)以石墨居多，一般較脆，過度受力極易引起碎裂；三是安裝、拆卸困難，極易損壞靜環(huán)。4．葉輪鎖母越緊越好？機(jī)械密封泄漏中，軸套與軸之間的泄漏（軸間泄漏）是比較常見的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實(shí)導(dǎo)致軸間泄漏的因素較多，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導(dǎo)致軸間泄漏。鎖母鎖緊過度只會導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運(yùn)轉(zhuǎn)中鎖母會自動適時鎖緊。</p><p> 在靜環(huán)表面開圓弧形凹槽可形成流體動力密封，增加流體膜承載能力，改善端面潤滑條件，有效延長機(jī)封工作壽命。在端面配對方面，碳化鎢一M106K石墨組對（即動、靜環(huán)材料）一般要優(yōu)于其他材料，因為其潤滑性好，摩擦系數(shù)低，導(dǎo)熱性也比較好。2、選擇合適的端面比壓。低溫密封由于端面潤滑性差，容易發(fā)生氣化、結(jié)冰，所以在保證密封可靠的前提下，端面比壓可適當(dāng)減小。一般機(jī)械密封比壓值推薦為，對低溫密封可取其下限。對金屬波紋管機(jī)械密封，由于動環(huán)沒有軸向摩擦，端面比壓甚至可以低于下限。3、工藝上采取相應(yīng)措施。如盡量減少介質(zhì)的含水量；保持密封腔壓力的相對穩(wěn)定；盡可能配備沖洗冷卻裝置；在設(shè)備啟動前，對機(jī)封部位進(jìn)行適當(dāng)預(yù)熱等。三、高速下的機(jī)械密封當(dāng)轉(zhuǎn)速超過3000r/min或者摩擦副的線速度超過25m/s時，一般可視為高速密封。在高速條件下，摩擦端面由于線速度很大，摩擦產(chǎn)生的熱量也多，此時端面液膜不容易形成，磨損加劇。高速還容易引起旋轉(zhuǎn)環(huán)的振動，并受到較大的離心力作用，不利于端面間液膜的形成和維持。所以在高速情況下，為了減小離心力和振動的影響，應(yīng)盡量減少轉(zhuǎn)動部件，采用彈簧靜止式結(jié)構(gòu)。也可以加強(qiáng)對摩擦副端面的冷卻和潤滑。襄樊五二五機(jī)械密封HTM-40S315Z。</p><div

所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。3、選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補(bǔ)償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。二、低溫下的機(jī)械密封在煉油化工裝置中，低溫輸送的介質(zhì)一般都具有豁度小、潤滑性差、容易氣化的特點(diǎn)，而且介質(zhì)在氣化時大量吸熱，使周圍溫度急劇下降，造成空氣中水氣的凝結(jié)，導(dǎo)致端面及其周圍結(jié)冰，使端面貼合不嚴(yán)引起泄漏。同時，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時轉(zhuǎn)移，必然會加劇端面處的氣化，造成惡性循環(huán)，加速密封面的早期失效。另外，低溫密封的輔助密封圈在低溫下發(fā)硬失彈也容易導(dǎo)致泄漏。對低溫密封，除了選擇合適的輔助密封圈材質(zhì)外，還要注意以下幾點(diǎn)：1、改進(jìn)密封結(jié)構(gòu)及正確選擇摩擦副材料。實(shí)踐證明。HTM-55S351Z襄樊五二五機(jī)械密封。太原襄樊五二五機(jī)械密封IH-35S300</p><p
