Amathangi Okugcina Esikhungo Sedatha
Isikhungo sedatha sincike emithonjeni emithathu yamanzi - ukuvikelwa komlilo (NFPA 22), amanzi okwengeza/inqubo kanye nebhafa lamanzi apholile noma isitoreji sokushisa - ngayinye inezinga layo kanye nomsebenzi wayo. Amathangi e-GFS aboshiwe, e-epoxy, ensimbi engagqwali, e-galvanized kanye namathangi ashiselwe, kanye nemikhumbi ye-ASME, kukhona konke lokhu; khetha ngokulingana kwamanzi, ingcindezi kanye nesidingo sokuqina, hhayi ngelebula.
Abasebenzi bezikhungo zedatha abahlela amasistimu okupholisa, ukuvikelwa komlilo kanye namanzi enqubo bahlala bebuza umbuzo owodwa osebenzayo: yiluphi ithangi lokugcina amanzi oludingwa yilo msebenzi, futhi licaciswa kanjani? Le ndatshana igxile ku-"Amathangi Okugcina Amanzi Esikhungo Sedatha", ehlanganisa amathangi okugcina ezikhungweni zedatha ngokujwayelekile. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe emazingeni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olulungile, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Izingxenye Ezintathu Zamanzi Esikhungo Sedatha Esingakwazi Ukuzishiya
· Ukuvikelwa komlilo. I-NFPA 22 igcina umthamo wamanzi ozinikezelwe, ogcwaliswa ngokuthembekile wezinhlelo zokufafaza / ze-deluge; lokhu akunakuxoxiswana ngakho ezindaweni ezibalulekile.
· Ukugcwalisa / inqubo. Imibhoshongo yokupholisa kanye nokufaka umswakama kusebenzisa amanzi okugcwalisa ngokuqhubekayo; ithangi lokugcina ligcina umjikelezo uzinzile ngesikhathi sokuphazamiseka kokuhlinzekwa.
· Ibhafa yamanzi apholile kanye ne-TES. Amathangi ebhafa ahlukanisa ama-chiller emthwalweni; ukugcinwa kwamandla ashisayo kuhambisa ukupholisa emahoreni angenamsebenzi futhi kunezela ukuqina kwe-N+1.
Kungani Amathangi Ehlezi Enkabeni Yenqubo Yokupholisa
· Ukupholisa inkinga yamanzi. Ukonga ngasohlangothini lomoya nangasohlangothini lwamanzi, imibhoshongo kanye nemijikelezo epholile konke kuhambisa amanzi; ukugcinwa yikho okwenza lokho kuhamba kuqhubeke futhi kulawuleke.
· Ukuminyana nokwehluleka. Amathangi anikeza kokubili isisindo sokushisa kanye nesivikelo se-hydraulic, okwenza kube lula ukuqala kwe-compressor nokukhokhela ukudluliswa kwepompo noma kwezinsiza.
· Indawo yokuma kanye nesivinini. Amathangi aboshiwe anciphisa umsebenzi wokwakha futhi angakhiwa eduze kwesikhungo samandla, okwenza kube lula uhambo olubalulekile lokwakha i-DC.
Lokho Isayithi le-AI / Hyperscale elikudingayo Ngendlela Ehlukile
· Ukushisa okuphezulu nokuminyana. Ama-rack e-AI anyusa i-kW nge-rack ngaphezu kwe-IT yakudala; umthamo wamanzi okupholisa kanye nomthamo we-TES kukhula nalokho kuminyana.
· Ukuqina ngaphezu kwezindleko. Abasebenzi be-hyperscale ne-colocation babeka isisindo esikhulu ekusebenzeni ngaso sonke isikhathi naku-N+1; umthamo wethangi ucaciswa esimweni esibi kakhulu sokudlulisa, hhayi nje isimo esizinzile.
· Ukuhlanganiswa nezilawuli. Amathangi awasasebenzi wodwa - anikeza izimpawu ze-BMS / EPMS zezinga, izinga lokushisa kanye nesimo sephampu.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. Indawo yokugcina ye-NFPA 22 igcinwa ihlukile emanzini okusebenza.
· Ukugcwalisa okupholisa. Ukushintshwa okungapheli kokulahlekelwa komhoshongo/isihumusho.
· Isivikelo esipholile / i-TES. Ukuhlukanisa nokugcina ukushisa ngaphandle kwesikhathi esiphakeme.
· Inqubo namanzi okuphuza. Ukudla kwesiteshi sokubilisa, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha Nokuqhathanisa
Khetha ngokwezinga lamanzi, ingcindezi kanye nemfuneko yokuqina esikhundleni somaka. I-GFS eboshiwe nensimbi ehlanganiswe nge-epoxy ziyakhiwa ngokushesha ezindaweni eziqinile ze-DC futhi zihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi edayisiwe noma ukhonkolo kufaneleka izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umkhathi.

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 egqwalisiwe 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 emisebenzini yamaphrojekthi emazweni angaphezu kwe-100. Kuyo yonke indawo yesikhungo sedatha umkhiqizi ofanayo angakwazi ukubhekana nemisebenzi yokuvikela umlilo, yokwengeza kanye neyokugcina amanzi abandayo, kanye nophahla lwedome le-geodesic le-aluminium kanye nemikhumbi yengcindezi ye-ASME lapho umklamo udinga khona.
Imibuzo Evame Ukubuzwa
Umbuzo: Yimaphi amathangi amanzi adingwa isikhungo sedatha?
Impendulo: Izindima ezintathu: indawo yokugcina yokuvikela umlilo (NFPA 22), ithangi lokwengeza/inqubo yemishini yokupholisa kanye nokufaka umswakama, kanye ne-buffer yamanzi abandayo noma isitoreji samandla okushisa. Ngayinye inesilinganiso sayo kanye nomsebenzi wayo.
Umbuzo: Kungani amathangi abalulekile ekupholiseni isikhungo sedatha?
Impendulo: Ukupholisa kuhambisa amanzi - ngokusebenzisa imibhoshongo, amapuleti nemijikelezo - futhi isitoreji senza lokho kugeleza kuqhubeke futhi kulawuleke. Amathangi engeza kokubili isisindo sokushisa kanye nesivikelo se-hydraulic esenza ukuqala kwe-compressor kube bushelelezi.
Umbuzo: Yini edingwa isikhungo sedatha se-AI ngendlela ehlukile?
Impendulo: Ukukhula kokuminyana kwama-rack kukhulisa umthamo wamanzi okupholisa kanye nomthamo we-TES; isisindo sesikhathi sokusebenza (N+1) siyakhula; futhi amathangi adlulisela izimpawu ze-BMS/EPMS esikhundleni sokuma wodwa.
Umbuzo: Yimiphi imithombo efanele amathangi amanzi esikhungo sedatha?
Impendulo: I-GFS, i-epoxy ehlanganiswe nge-fusion, insimbi engagqwali, insimbi egcwelisiwe kanye nensimbi edayisiwe ngokushisela ngayinye iyafaneleka emsebenzini othile; i-NSF/ANSI 61 ibalulekile lapho amanzi aseduze namanzi okuphuza. Amathangi aboshiwe anciphisa umsebenzi wokwakha futhi asheshisa ukwakhiwa.
Umbuzo: Ingabe amathangi esikhungo sedatha asezingeni elilinganayo?
Impendulo: Alikho ithangi elilodwa elilingana nakho konke; imisebenzi yomlilo, yokugcwalisa nokopholisa icaciswa ngokwehlukana ngokwezinga (NFPA 22, AWWA D103-09/D100) nangemfuneko yokuqina.
Umbuzo: Amathangi ahlangana kanjani nezilawuli ze-DC?
Impendulo: Izinga, izinga lokushisa kanye nesimo sephampu kubikwa ku-BMS/EPMS; amathangi omlilo engeza izexwayiso zezinga/izinga lokushisa/ukugqekeza kuphaneli yomlilo.
Kuma-"Data Center Storage Tanks", indlela esebenzayo iwukuqala emsebenzini - izinga lamanzi, ingcindezi, umthamo kanye nesidingo sokuqina - bese uvumela izinga (NFPA 22, AWWA D103-09/D100, ASME BPVC VIII, NSF/ANSI 61) linqume uhlobo lwethangi kanye nempahla. Ukugcinwa kwamanzi esikhungweni sedatha kuyisinqumo sezinhlelo, hhayi ukuthenga kwempahla; ukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesipikhi sokugcinwa kwamanzi e-DC sakho sokupholisa, sokwengeza noma sokugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
