賓陽泵類機械的密封裝置優化對策

　　泵類賓陽機械密封不嚴

，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

　　密封材料直接影響賓陽機械密封效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賓陽機械密封的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。

　　強化密封控製能力

　　本著“引進來與走出去”原yuan則ze
，多duo在zai實shi踐jian總zong結jie基ji礎chu上shang加jia強qiang新xin技ji術shu與yu新xin材cai料liao的de引yin入ru，以yi切qie實shi提ti高gao機ji械xie的de密mi封feng能neng力li。尤you其qi是shi利li用yong非fei接jie觸chu式shi或huo回hui流liu式shi等deng密mi封feng控kong製zhi技ji術shu
，能neng夠gou有you效xiao改gai善shan密mi封feng效xiao果guo。回hui流liu式shi密mi封feng技ji術shu能neng夠gou通tong過guo優you化hua回hui流liu路lu徑jing的de途tu徑jing，改gai變bian以yi往wang的de機ji械xie流liu體ti泄xie漏lou過guo程cheng，通tong過guo機ji械xie傳chuan導dao的de作zuo用yong，將jiang外wai泄xie流liu體ti自zi動dong回hui流liu。當dang密mi封feng裝zhuang置zhi的de作zuo用yong發fa揮hui受shou限xian時shi
，回hui流liu式shi技ji術shu會hui通tong過guo引yin流liu策ce略lve
，促cu使shi外wai泄xie流liu體ti重zhong回hui到dao機ji械xie內nei。從cong非fei接jie觸chu式shi密mi封feng技ji術shu入ru手shou分fen析xi，主zhu要yao是shi對dui動dong靜jing環huan的de接jie觸chu端duan麵mian調tiao整zheng後hou
，建jian立li新xin的de賓陽機械密封體ti係xi，介jie質zhi泄xie露lu後hou會hui受shou動dong靜jing壓ya的de影ying響xiang，在zai密mi封feng端duan麵mian中zhong穿chuan梭suo
，通tong過guo流liu體ti流liu動dong方fang式shi形xing成cheng流liu體ti膜mo，以yi往wang的de動dong靜jing環huan位wei置zhi同tong時shi發fa生sheng變bian化hua。而er流liu體ti膜mo能neng夠gou控kong製zhi流liu體ti流liu動dong方fang向xiang
，可ke防fang止zhi動dong靜jing環huan發fa生sheng磨mo損sun

，從cong而er進jin一yi步bu強qiang化hua耐nai受shou力li與yu密mi封feng能neng力li。
