連平泵類機械的密封裝置優化對策

　　泵類連平機械密封不嚴，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
