青羊泵類機械的密封裝置優化對策

　　泵類青羊機械密封不嚴，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

　　密封材料直接影響青羊機械密封效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

，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青羊機械密封的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。
