水泵的機(jī)械密封亦稱端面密封,其有一對垂直于旋轉(zhuǎn)軸線的端面,該端面在流體壓力及補(bǔ)償機(jī)械外彈力的作用下,依賴輔助密封的配合與另一端保持貼合,并相對滑動(dòng),從而防止流體泄漏。 </p> <p> 一、機(jī)械密封常見的滲漏現(xiàn)象 </p> <p> 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: </p> <p> 1.機(jī)械密封周期性滲漏 </p> <p> (1)防爆自吸泵轉(zhuǎn)子軸向竄動(dòng)量大,輔助密封與軸的過盈量大,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，江蘇銷售密封私人定做，江蘇銷售密封私人定做,得不到補(bǔ)償位移。 </p> <p> 對策: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)。 </p> <p> (2)密封面潤滑油量不足引起干摩擦或拉毛密封端面。 </p> <p> 對策:油室腔內(nèi)潤滑油面高度應(yīng)加到高于動(dòng)、靜環(huán)密封面。 </p> <p> (3)轉(zhuǎn)子周期性振動(dòng)。原因是定子與上、下端蓋未對中或葉輪和主軸不平衡,汽蝕或軸承損壞(磨損) ，江蘇銷售密封私人定做,這種情況會(huì)縮短密封壽命和產(chǎn)生滲漏。 </p> <p> 對策:可根據(jù)維修標(biāo)準(zhǔn)來糾正上述問題。在裝配機(jī)械密封前機(jī)封組件清洗不潔凈，組件碰傷或劃傷；裝配不到位；彈簧裝偏、緊固螺釘沒緊固。江蘇銷售密封私人定做</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

迷宮效應(yīng)：軸在微觀下表面非常的不平整，與盤根只能部分貼合，而部分未接觸，所以在盤根和軸之間著微小的間隙，像迷宮一樣，帶壓介質(zhì)在間隙中多次被節(jié)流，從而達(dá)到密封的作用。 </p> <p> 軸承效應(yīng)：在盤根填料和軸之間會(huì)存在著一層薄薄液膜，使盤根填料和軸類似于滑動(dòng)軸承，起到了一定的潤滑作用，從而避免了盤根和軸的過度磨損。 </p> <p> 盤根填料對材料的要求 </p> <p> 由于受密封介質(zhì)的溫度、壓力、PH，以及設(shè)備的線速度、表面粗糙度、同軸度、徑跳、偏心等因素，就要求盤根材料具有以下特點(diǎn)： </p> <p> 1、有一定的彈塑性 </p> <p> 2、化學(xué)穩(wěn)定性 </p> <p> 3、不滲透性 </p> <p> 4、自潤滑性 </p> <p> 5、耐溫性 </p> <p> 6、拆裝方便 </p> <p> 7、制造簡單，價(jià)格低廉。 </p> <p> 上述材料特性直接影響著盤根填料的密封性能和使用壽命，而能完全符合上述所有性能的材料很少，所以獲取質(zhì)量的密封材料和提高其材料性能，一直是密封領(lǐng)域研究的重點(diǎn)。江蘇銷售密封私人定做為延長其密封壽命，除了選擇恰當(dāng)?shù)哪Σ粮辈牧虾秃线m的端面比壓外，正確的安裝和維修也可起到重要的作用。</p><div
