點軍泵類機械的密封裝置優化對策

　　泵類點軍機械密封不嚴，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

　　mifenganzhuangguochengzhong，gongzuorenyuanweiguifanjinxingshebeimifengxingnengdejiashuihuojingyashiyan，wufaquebaomifengxingneng。mifenghuanyajinyumifenghuancunzaiyiwuhuomifengshousundengyuanyin
，douhuiyinqijiezhixielu。

　　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

　　零ling部bu件jian受shou力li不bu均jun勻yun或huo受shou到dao熱re量liang衝chong擊ji的de影ying響xiang等deng情qing況kuang下xia，易yi發fa生sheng密mi封feng裝zhuang置zhi損sun壞huai後hou泄xie露lu的de問wen題ti。為wei提ti高gao泵beng類lei機ji械xie的de應ying用yong價jia值zhi，避bi免mian介jie質zhi泄xie露lu引yin起qi的de生sheng產chan事shi故gu
，加jia強qiang密mi封feng改gai進jin的de研yan究jiu意yi義yi重zhong大da。
