龍灣泵類機械的密封裝置優化對策

　　泵類龍灣機械密封不嚴，產生介質泄漏現象後
，將直接威脅石化裝置的安全性。產生泄漏的原因有以下幾方麵;

　　一是人為操作因素影響

　　密mi封feng安an裝zhuang過guo程cheng中zhong
，工gong作zuo人ren員yuan未wei規gui範fan進jin行xing設she備bei密mi封feng性xing能neng的de加jia水shui或huo靜jing壓ya試shi驗yan，無wu法fa確que保bao密mi封feng性xing能neng。密mi封feng環huan壓ya緊jin與yu密mi封feng環huan存cun在zai異yi物wu或huo密mi封feng受shou損sun等deng原yuan因yin
，都dou會hui引yin起qi介jie質zhi泄xie露lu。

　　二是環境變化因素影響

　　石化裝置的生產環境複雜，環境變化也會直接影響密封性能。裝置震動會促使內部密封環等部件發生脫落;溫度變化會促使動靜環產生縫隙;出現憋壓或氣蝕現象，也會對密封環產生氣化等形式的衝擊
，從而出現不同範圍的泄露問題。

　　三是密封受壓影響因素
