普陀泵類機械的密封裝置優化對策

　　泵類普陀機械密封不嚴
，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

　　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。

　　合理選用密封材料

　　密封材料直接影響普陀機械密封效xiao果guo，當dang動dong靜jing環huan的de材cai料liao強qiang度du不bu達da標biao時shi，受shou環huan境jing變bian化hua因yin素su的de影ying響xiang較jiao大da，更geng易yi產chan生sheng泄xie露lu的de問wen題ti。在zai現xian代dai科ke技ji發fa展zhan帶dai動dong下xia
，材cai料liao的de種zhong類lei與yu性xing能neng得de到dao了le飛fei速su的de發fa展zhan
，密mi封feng裝zhuang置zhi的de材cai料liao更geng具ju有you選xuan擇ze性xing。傳chuan統tong密mi封feng裝zhuang置zhi以yi碳tan石shi墨mo的de密mi封feng材cai料liao為wei主zhu，利li用yong硬ying質zhi合he金jin與yu軟ruan質zhi材cai料liao結jie合he設she計ji成cheng密mi封feng裝zhuang置zhi，如ru普陀機械密封的de密mi封feng圈quan

，有you聚ju四si氟fu乙yi烯xi與yu合he成cheng橡xiang膠jiao等deng類lei型xing的de材cai料liao，但dan應ying用yong效xiao果guo不bu盡jin理li想xiang
，受shou環huan境jing變bian化hua的de影ying響xiang較jiao大da。材cai料liao生sheng產chan技ji術shu飛fei速su發fa展zhan，納na米mi材cai料liao與yu自zi潤run滑hua合he金jin等deng高gao性xing能neng的de材cai料liao應ying運yun而er生sheng，利li用yong自zi身shen的de熔rong點dian低di與yu潤run性xing能neng高gao等deng優you勢shi特te征zheng，運yun用yong在zai密mi封feng裝zhuang置zhi設she計ji中zhong，更geng利li於yu提ti高gao泵beng類lei機ji械xie的de密mi封feng穩wen定ding性xing
，促cu使shi泵beng類lei機ji械xie安an全quan可ke靠kao運yun行xing。
