生產(chǎn)環(huán)節(jié)中的漏水現(xiàn)象使用環(huán)節(jié)中的漏水現(xiàn)象(1)壓力造成滲漏。使用中當(dāng)密封腔內(nèi)壓力>3MPa時(shí)，可能導(dǎo)致端面比壓過大,液膜難以成，密封端面磨損嚴(yán)重，發(fā)熱量增多，造成密封面熱變形。而泵在啟動(dòng)、停機(jī)過程中，由于泵進(jìn)口堵塞，抽送介質(zhì)中含有氣體等原因，可能使密封腔出現(xiàn)負(fù)壓，繼而引起密封端面干摩擦，內(nèi)裝式機(jī)械密封會(huì)產(chǎn)生漏水現(xiàn)象。(2)介質(zhì)問題。首先，由于密封圈等輔助元件常采用不耐酸堿和高溫的有機(jī)材料，當(dāng)介質(zhì)中含有弱酸、弱堿時(shí)，長期的使用會(huì)使其失去彈性甚至腐爛;而介質(zhì)中出現(xiàn)固體顆粒等物質(zhì)時(shí)，也會(huì)劃傷端面造成磨損，同時(shí)水垢、油污等也可能在軸表面造成堆積。此外，水溫超標(biāo)也是導(dǎo)致機(jī)械密封性能下降的主要原因，因此當(dāng)熱交換器的冷卻能力不足時(shí)，密封的使用壽命常會(huì)較大縮短。(3)旋動(dòng)環(huán)和靜止環(huán)疲勞損壞。給水泵軸線不一致或者軸承間隙調(diào)整不當(dāng)都會(huì)引起給水泵的振動(dòng)，而振動(dòng)會(huì)導(dǎo)致機(jī)械密封組件中的動(dòng)靜部分發(fā)生摩擦，即使其接觸面的水膜發(fā)生破壞，導(dǎo)致其失去水膜潤滑而損壞。
