Amathangi Amanzi Ezikhungo Zedatha: Inselele Ekabili Yokupholisa Nokuvikela Umlilo
Amathangi amanzi esikhungo sedatha abhekana nenselelo ekabili: uhlangothi lokupholisa (umjikelezo wamanzi abandayo, i-reserve yokugcwalisa kanye nokugcinwa kwamandla okushisa) kanye nohlangothi lomlilo (i-reserve ezinikezelwe ye-NFPA 22 okufanele ihlale igcwele futhi ihlukene). Zixazulula izinkinga ezihlukene ngaphansi kwezindinganiso ezihlukene futhi akufanele zihlanganishwe, kodwa umhlinzeki oyedwa angasebenzisa kokubili - umlilo, ukugcwalisa kanye nemisebenzi yokupholisa - ngaphansi kohlelo olulodwa lwekhwalithi ukuze kuncishiswe ingozi yokuxhumana. Uhlangothi lomlilo lusekelwa lapha iphrojekthi yangempela ye-NFPA 22; uhlangothi lokupholisa lubhekwa ngobuchwepheshe bamathangi afakazelwe afanayo ngaphandle kokusho ireferensi ethile yokupholisa yesikhungo sedatha.
Uhlelo lwamanzi lwesikhungo sedatha luthwala izimfuno ezimbili okulula ukuzidida futhi okuyingozi ukuzihlanganisa: umjikelezo wokupholisa ogcina i-IT iphila, kanye nesigcino somlilo esivikela ukuphila nempahla. Le ndatshana ibhekana ngqo nenselele ekabili - lokho ohlangothi ngalunye oludingayo, kungani kufanele bahlale behlukene, nokuthi umhlinzeki wethangi elilodwa angakwazi kanjani ukuxhumanisa kokubili ngaphandle kokulimaza noma yikuphi. Ibhalelwe onjiniyela nabanikazi abalinganisela ukuthengwa okukodwa ngokumelene nabahlinzeki abahlukanisiwe.
Izimfuno Ezimbili, Indawo Eyodwa
Iphutha ukuklama ithangi elilodwa ukuthi lisebenzele kokubili - alivikeli noma yikuphi ngokuthembekile.
· Uhlangothi lokupholisa. Umjikelezo wamanzi abandayo, i-reserve yokugcwalisa kanye ne-TES kugcina ihholo ledatha ngaphansi komkhawulo walo wokushisa.
· Uhlangothi lomlilo. I-NFPA 22 reserve ezinikezelwe ivikela ukuphepha kokuphila futhi isekela ukugunyazwa kokuhlala.
· Amakhosi ahlukene. Omunye uphendula ku-uptime ne-PUE; omunye uphendula kukhodi kanye nomshuwalense.
Uhlangothi Lokupholisa: Amanzi Abandayo, Ukugcwalisa Kanye Ne-TES
Akukho phrojekthi ethile yokupholisa yesikhungo sedatha eshiwo lapha; izimangalo zohlangothi lokupholisa zincike kubuchwepheshe bethangi eliqinisekisiwe kanye nezibalo zomsebenzi ezishicilelwe, hhayi ekufakweni okubhekiselwe kukho.
· Isibhafa esipholile. Ihlukanisa isipholisi emishini yokushintsha umthwalo; imizuzu engu-3-15 yokusebenza kwesipholisi ku-design delta-T.
· Isigcinamafa sokugcwalisa. Sithatha indawo yokuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi nokugezwa; i-NSF/ANSI 61 uma iseduze namanzi okuphuza.
· Ukugcinwa kokushisa. I-TES ehlukanisiwe isusa ukupholisa ngezikhathi ezingaphandle kwesikhathi esimatasa futhi yengeza ukuqina ngesikhathi sokuphazamiseka.
· Ubuchwepheshe. La mathangi afanayo e-GFS aboshiwe kanye ne-fusion-bonded epoxy aqinisekisiwe ku-NSF/ANSI 61 asebenza kulolu hlangothi.
Uhlangothi Lomlilo: Indawo Yokugcina Ezinikezelwe Ye-NFPA 22
· Igcwele njalo. I-NFPA 22 idinga indawo yokugcina ezinikezelwe, egcwaliswa ngokuthembekile enepayipi elihlala njalo.
· Okulawulwa ubude besikhathi. Ngokuvamile amahora angu-2-4 okugeleza kwepompo yomlilo; amakhempasi amakhulu agcina isikhathi esithe xaxa.
· Kukhala izexwayiso. Amazinga, izinga lokushisa kanye nezexwayiso zokugqekeza zihamba ziya kuphaneli yomlilo.
Kungani Kufanele Bahlale Behlukene
· Ukutholakala. Amanzi omlilo kufanele atholakale ngesikhathi somcimbi kungakhathalekile isimo senqubo.
· Ikhwalithi yamanzi. Ukuxubana kungaba yingozi yokungcolisa umjikelezo wokupholisa.
· Inhloso yekhodi. I-NFPA 22 ihlukanisa umlilo kwinqubo ngokwakhiwa.
Ukuxhumanisa Kokubili Nomhlinzeki Omunye Wethangi
· Uhlelo olulodwa lwekhwalithi. Uhlelo olulodwa lwe-ISO 9001/45001 luqinisekisa amathangi omlilo, okugcwalisa kanye namanzi abandayo.
· Isixhumanisi esisodwa. Ukulinganisa, imithwalo yesisekelo, ama-nozzle nama-alamu kuyahlanganiswa, akuxoxiswani ngakho phakathi kwabathengisi.
· Izinsiza zokungezelelwa nokusekelwa. Umhlinzeki oyedwa wenza lula umjikelezo wokuphila weminyaka eyi-10-15.

Isifundo Sombandela Wephrojekthi
Uhlangothi lomlilo lwenselele ekabili lusekelwa iphrojekthi yokuvikela umlilo elethwa ngempela: i-Center Enamel yahlinzeka ngamathangi okuvikela umlilo e-NFPA 22 emaphrojekhini emazweni angaphezu kwe-100 kusetshenziswa ubuchwepheshe obufanayo be-GFS eboshiwe kanye ne-fusion-bonded epoxy obusebenza ekuvikelweni komlilo kwesikhungo sedatha. Iphrojekthi engezansi iwukufakwa kokuvikela umlilo okumbozwe nge-epoxy (FBE); ifakiwe ngoba ubunjiniyela bayo bokugcina okukhethekile buyinqubo efanayo elandelwa uhlelo lomlilo lwesikhungo sedatha. Akukho phrojekthi ethile yokupholisa isikhungo sedatha efakazwayo.

Ubungcweti Benkampani
UCenter Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.), umkhiqizi wamathangi okugcina axhunywe ngezibophezelo futhi ashiselwe owasungulwa ngo-2008, ukhiqiza amathangi e-Glass-Fused-to-Steel (GFS), i-epoxy ehlanganiswe ngokuncibilika, insimbi engagqwali, insimbi egayiwe kanye namathangi ashiselwe kanye nophahla lwedome le-geodesic le-aluminium kanye nemikhumbi yengcindezi ye-ASME. Imikhiqizo yamathangi ayo iqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi isidluliselwe emaphrojekthi emazweni angaphezu kwe-100. Ohlelweni lwedatha yesikhungo, iphuzu elisebenzayo ukuqinisekisa izitifiketi, amaphrojekthi okubhekiselwa kuwo kanye nokwesekwa kobunjiniyela ngaphambi kokunikezwa - amandla, hhayi intengo kuphela, avikela impilo yesikhungo yeminyaka eyi-10-15. Umkhiqizi ofanayo angakwazi ukubhekana nemisebenzi yokuvikela umlilo, yokugcwalisa kanye namanzi abandayo, kanye nophahla lwedome le-geodesic le-aluminium kanye nemikhumbi yengcindezi ye-ASME lapho umklamo udinga khona.
Imibuzo Evame Ukubuzwa
Umbuzo: Yini inselelo ekabili yamathangi amanzi esikhungo sedatha?
Impendulo: Izidingo ezimbili ezihlukene endaweni eyodwa: umjikelezo wokupholisa (amanzi abandayo, ukugcwalisa, i-TES) ovikela isikhathi sokusebenza, kanye nendawo yokugcina yomlilo ye-NFPA 22 ezinikezelwe evikela ukuphepha kokuphila. Zixazulula izinkinga ezihlukene ngaphansi kwezindinganiso ezihlukene.
Umbuzo: Kungani amanzi omlilo namanzi okupholisa kufanele ahlale ehlukene?
Impendulo: Amanzi omlilo kufanele abe khona ngesikhathi somcimbi kungakhathalekile isimo senqubo; ukuxubana kungabeka engcupheni ukungcolisa umjikelezo wokupholisa futhi kwephule inhloso ye-NFPA 22. Ukwehlukanisa kuqinisekisa kokubili.
Umbuzo: Ingabe ithangi elilodwa lingasebenza kokubili umsebenzi wokupholisa nowomlilo?
A: Hhayi ngokuhambisana. I-NFPA 22 idinga indawo yokugcina umlilo ezinikezelwe, egcwele njalo enepayipi elihlala likhona. Ukuhlanganisa imisebenzi kungabeka ingozi yokushoda kwesistimu yomlilo noma ukungcola kwendlela yokupholisa.
Q: Yibuphi ubuchwepheshe bethangi obusebenza ohlangothini lokupholisa lwesikhungo sedatha?
A: Amathangi e-Bolted Glass-Fused-to-Steel kanye ne-fusion-bonded epoxy aqinisekisiwe ku-NSF/ANSI 61 asebenza emisebenzini ye-chilled buffer, makeup kanye ne-TES; i-buffer noma isitsha esicindezelwe sizosebenzisa i-ASME BPVC Section VIII.
Q: Likhulu kangakanani ithangi lamanzi omlilo lesikhungo sedatha?
A: Lilinganiswa ngokugeleza kwepompo yomlilo x isikhathi ngaphansi kwe-NFPA 22, ngokuvamile amahora angu-2-4, namakhampasi amakhulu agcina okwengeziwe ukuze kube nokuphendula okuhamba ngezigaba. Umthamo osebenzayo (osebenzisekayo), hhayi ilebula yegama, uyabusa.
Q: Ingabe amathangi omlilo nawokupholisa kufanele avele kumhlinzeki oyedwa?
A: Ukuxhumanisa kokubili ngaphansi kohlelo lwekhwalithi lwe-ISO 9001/45001 kunciphisa ingozi yokuxhumana ekulinganiseni, imithwalo yesisekelo, ama-nozzle nama-alamu phakathi nomjikelezo wokuphila weminyaka eyi-10-15.
Q: Ingabe amathangi okupholisa esikhungo sedatha adinga i-NSF/ANSI 61?
A: Lapho amanzi okugcwalisa engamanzi okuphuza noma eduze namanzi okuphuza, yebo. Amanzi acwebile omjikelezo ovaliwe ngaphandle kokuxhumana namanzi okuphuza awadingi ngokuqinile, kodwa umcacisi nekhodi yikho okunqumayo.
Q: Ingabe iphrojekthi yokupholisa yesikhungo sedatha ibalulwe kulesi sihloko?
A: Cha. Isiqondiso sohlangothi lokupholisa sincike kubuchwepheshe bamathangi aqinisekisiwe kanye nezibalo zomsebenzi ezishicilelwe. Iphrojekthi yokuvikela umlilo okubhekiselwe kuyo iwukulethwa kwangempela kwe-NFPA 22 okubunjiniyela bamathangi aboshiwe okusebenza ohlangothini lomlilo lwesikhungo sedatha.
Izinselelo ezimbili zamathangi amanzi esikhungo sedatha empeleni ziyizinselelo ezimbili okufanele zihlelwe, zicaciswe futhi zinikezwe ngokwehlukana - uhlangothi lokupholisa lwesikhathi sokusebenza kanye nohlangothi lomlilo lwekhodi nokuphepha kokuphila - bese zixhumaniswa ngaphansi kohlelo olulodwa lwekhwalithi. Ukuzigcina zihlukene yikho okwenza zombili zithembeke.
Cela unjiniyela ukuthi axhumanise amathangi akho omlilo namanzi okupholisa esikhungo sedatha ngaphansi kwesicaciso esisodwa - indawo yokugcina eyisipesheli ye-NFPA 22 kanye ne-NSF/ANSI 61 yokugcwalisa nemisebenzi epholile, nezexwayiso ezihlanganiswe ne-BMS/EPMS kanye nephaneli lomlilo.
