專業級防爆監控維護
1、一切(qie)防爆(bao)監控均應樹(shu)立設(she)備(bei)(bei)檔(dang)案,從設(she)備(bei)(bei)裝(zhuang)置、試車、運轉、維(wei)修、直到設(she)備(bei)(bei)的防爆(bao)降級、報廢。應將各個不一樣時(shi)期的各種(zhong)技(ji)能數(shu)據(ju)收集完全,收拾歸(gui)檔(dang),并在設(she)備(bei)(bei)上逐個編號。
2、在爆破風險場所制(zhi)止帶電(dian)(dian)(dian)(dian)維修電(dian)(dian)(dian)(dian)氣設備和線(xian)(xian)路,制(zhi)止約時(shi)送電(dian)(dian)(dian)(dian)、停電(dian)(dian)(dian)(dian)。并應在斷電(dian)(dian)(dian)(dian)處掛上“有(you)人作(zuo)業,制(zhi)止合閘”的(de)警告(gao)牌。維修時(shi),如將防爆監控拆至安全區域進行,現(xian)場的(de)設備電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)纜線(xian)(xian)頭(tou)應做好(hao)防爆處置,并嚴(yan)禁(jin)通(tong)電(dian)(dian)(dian)(dian)。
3、防爆監控的進(jin)線(xian)(xian)口,有必要(yao)用(yong)橡膠密(mi)(mi)封(feng)(feng)圈密(mi)(mi)封(feng)(feng),制(zhi)(zhi)止用(yong)填(tian)充(chong)密(mi)(mi)封(feng)(feng)膠泥(ni)、石棉繩等其(qi)它方法代(dai)替;制(zhi)(zhi)止在腔體內填(tian)充(chong)任何物質(zhi)。失(shi)掉(diao)防爆功能;制(zhi)(zhi)止為了銜接(jie)便利,將進(jin)線(xian)(xian)口出的密(mi)(mi)封(feng)(feng)圈及與之(zhi)相(xiang)配的壓緊螺(luo)母棄除;制(zhi)(zhi)止多(duo)股(gu)單(dan)根導線(xian)(xian)兼并后經單(dan)孔彈性密(mi)(mi)封(feng)(feng)圈進(jin)入進(jin)線(xian)(xian)口。橡膠密(mi)(mi)封(feng)(feng)圈上的油污(wu)應擦(ca)拭潔凈,避(bi)免老化蛻變(bian)。
廠區化(hua)工(gong)生(sheng)產、加工(gong)、運輸和貯存的(de)各(ge)(ge)過程(cheng)(cheng)中,經(jing)常可(ke)能(neng)泄漏和溢散(san)出各(ge)(ge)種(zhong)各(ge)(ge)樣的(de)易(yi)燃、易(yi)爆(bao)(bao)氣體、液體和各(ge)(ge)種(zhong)粉塵及纖(xian)維,這類物(wu)質(zhi)與空氣混(hun)(hun)合(he)后,將變成易(yi)發生(sheng)爆(bao)(bao)炸(zha)危(wei)險(xian)(xian)的(de)混(hun)(hun)合(he)物(wu),它周圍的(de)場所也成了(le)程(cheng)(cheng)度不(bu) 同的(de)爆(bao)(bao)炸(zha)危(wei)險(xian)(xian)場所。當易(yi)爆(bao)(bao)物(wu)的(de)濃(nong)度達(da)到爆(bao)(bao)炸(zha)的(de)臨界點,一旦出現引爆(bao)(bao)源便會產生(sheng)爆(bao)(bao)炸(zha)、火災(zai)等(deng)嚴(yan)重事故(gu),造(zao)成人員傷亡和財產損(sun)失。
在各防爆區域內正(zheng)確安(an)(an)裝、使用(yong)防爆應用(yong)電(dian)視設備(bei)是(shi)必(bi)要的,可有效降低各種(zhong)安(an)(an)全隱患。使用(yong)防爆應用(yong)電(dian)視產品時嚴格按照操作規程也是(shi)防爆安(an)(an)全落實之(zhi)處。
利用成熟的視(shi)頻技術(shu)對廠區(qu)重要生產設備和(he)場(chang)(chang)景(jing)進(jin)行宏觀監(jian)控,并顯示和(he)記錄現場(chang)(chang)圖像(xiang)的系統。工業視(shi)頻監(jian)控系統(CCTV)重點是(shi)對廠區(qu)內的罐體、甲醇(chun)裝置區(qu)、變電站(zhan)、KAM裝置區(qu)、公用工程等(deng)場(chang)(chang)所進(jin)行視(shi)頻監(jian)視(shi)和(he)錄像(xiang)。
工業視頻(pin)系統應具(ju)備以太網通訊接口和網絡功能(neng)。可自(zi)動(dong)控制該區域的攝像機圖像切換并(bing)實現一個月長延時(shi)存儲(chu)。使值班人員不僅能(neng)通過實時(shi)圖像迅速地(di)掌握現場動(dong)態情況(kuang),還能(neng)通過查閱錄像數據(ju)對已發生事件進行檢(jian)索取證。
