Amathangi okugcina amanzi: ingxenye ebalulekile yenqubo yokupholisa yesikhungo sedatha
Isikhungo sedatha sincike emithonjeni emithathu yamanzi - ukuvikelwa komlilo (NFPA 22), amanzi okwengeza/inqubo kanye nebhafa lamanzi apholile noma ukugcina ukushisa - ngayinye inezinga layo kanye nomsebenzi wayo. Amathangi e-GFS aboshiwe, e-epoxy, ensimbi engagqwali, e-galvanized kanye namathangi ashiselwe, kanye nemikhumbi ye-ASME, kuyazihlanganisa lezi; khetha ngokulingana kwamanzi, ingcindezi kanye nesidingo sokuqina, hhayi ngelebula.
Abaphathi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikelwa emlilweni kanye namanzi ezinqubo bahlala bebuza umbuzo owodwa ongokoqobo: yiliphi ithangi lokugcina elidingeka ngempela kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile ku-"Amathangi okugcina amanzi: ingxenye ebalulekile yenqubo yokupholisa yesikhungo sedatha", ehlanganisa amathangi njengengxenye ebalulekile yenqubo yokupholisa yedatha. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olufanele, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Izinhlobo Ezintathu Zamanzi Isikhungo Sedatha Esingakwazi Ukuzidlula
· Ukuvikelwa komlilo. I-NFPA 22 igcina umthamo wamanzi oqokiwe, ogcwaliswa ngokuthembekile wamasistimu e-sprinkler / e-deluge; lokhu akunakuxoxiswana ngakho ezindaweni ezibalulekile.
· Ukwengeza / inqubo. Imibhoshongo yokupholisa kanye nokufaka umswakama kusebenzisa amanzi okwengeza ngokuqhubekayo; ithangi lokugcina ligcina umjikelezo uzinzile ngesikhathi sokuphazamiseka kokuhlinzekwa.
· Ibhafa lamanzi apholile kanye ne-TES. Amathangi ebhafa ahlukanisa ama-chiller emthwalweni; ukugcinwa kwamandla ashisayo kushintsha ukupholisa kube yizikhathi ezingaphandle kwesikhathi esimatasa futhi kwengeza ukuqina kwe-N+1.
Kungani Amathangi Ehlezi Enkabeni Yenqubo Yokupholisa
· Ukupholisa kuyinkinga yamanzi. Ukonga kwangaphandle komoya nangaphandle kwamanzi, imibhoshongo kanye nemijikelezo epholile konke kuhambisa amanzi; ukugcinwa yikho okwenza lokho kuhamba kuqhubeke futhi kulawuleke.
· Ukuminyana nokweqile. Amathangi anikeza kokubili isisindo sokushisa kanye nesigcawu se-hydraulic, okwenza kube lula ukuqala kwe-compressor nokumboza ukudluliswa kwepompo noma kwezinsiza.
· Indawo kanye nesivinini. Amathangi aboshiwe anciphisa umsebenzi womhlaba futhi angakhiwa eduze kwesikhungo samandla, okunciphisa indlela ebalulekile yokwakha i-DC.
Okudingwa Isayithi le-AI / Hyperscale Ngendlela Ehlukile
· Ukushisa okuphezulu nokuminyana. Ama-rack e-AI akhuphula i-kW nge-rack ngaphezu kwe-IT yakudala; umthamo wamanzi okupholisa kanye nomthamo we-TES kukhula nalokho kuminyana.
· Ukuqina ngaphezu kwezindleko. Abasebenzi be-hyperscale kanye ne-colocation babeka isisindo esikhulu ekusebenzeni ngesikhathi kanye ne-N+1; umsebenzi wethangi ucaciswa ukudluliswa kwezimo ezimbi kakhulu, hhayi isimo esizinzile kuphela.
· Ukuhlanganiswa nokulawula. Amathangi awasawona azimele - anikeza amasignali e-BMS / EPMS ezingeni, izinga lokushisa kanye nesimo sephampu.
Izimo Zokusetshenziswa
· Ukuvikela umlilo. Indawo yokugcina ye-NFPA 22 igcinwa ihlukile emanzini enqubo.
· Ukugcwalisa okupholisayo. Ukushintshwa okungapheli kokulahlekelwa kombhoshongo/isifudumezi.
· Ibhafa epholile / TES. Ukuhlukanisa nokugcina ukushisa okungekho esigabeni esiphakeme.
· Inqubo kanye namanzi okuphuza. Ukudla kwama-boiler, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha Nokuqhathanisa
Khetha ngokwekhwalithi yamanzi, ingcindezi kanye nemfuneko yokuqina esikhundleni somaka. I-GFS eboshiwe nensimbi ehlanganiswe nge-epoxy yakha ngokushesha ezindaweni eziqinile ze-DC futhi ihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi eshiselwe noma ukhonkolo kufaneleka izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umkhathi. Qinisekisa izitifiketi namaphrojekthi okubhekiselwe kuwo ngaphambi kokunikezwa.

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-aluminium geodesic 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-aluminium geodesic kanye nemikhumbi yengcindezi ye-ASME lapho umklamo udinga khona.
Imibuzo Evame Ukubuzwa
Umbuzo: Yimaphi amathangi amanzi adingwa isikhungo sedatha?
A: Izindima ezintathu: indawo yokugcina yokuvikela umlilo (NFPA 22), ithangi lokugcwalisa/inqubo yemishini yokupholisa kanye nokufaka umswakama, kanye nebhafa lamanzi apholile noma isitoreji samandla okushisa. Ngayinye inezinga layo kanye nomsebenzi wayo.
Umbuzo: Kungani amathangi abalulekile ekupholiseni isikhungo sedatha?
A: Ukupholisa kuhambisa amanzi - ngokusebenzisa imibhoshongo, amapuleti kanye namaluphu - futhi isitoreji senza lokho kugeleza kuqhubeke futhi kulawuleke. Amathangi engeza kokubili isisindo sokushisa kanye nebhafa le-hydraulic elenza 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 sokuqhubeka (N+1) siyakhula; futhi amathangi anikeza izimpawu ze-BMS/EPMS esikhundleni sokuma wodwa.
Umbuzo: Yiziphi izinto ezifanele amathangi amanzi esikhungo sedatha?
Impendulo: I-GFS, i-epoxy ehlanganiswe nge-fusion, insimbi engagqwali, insimbi egcwele i-zinc kanye nensimbi edayisiwe ngokushisela ngayinye ifanele umsebenzi wayo; i-NSF/ANSI 61 ibalulekile lapho amanzi aseduze namanzi okuphuza. Amathangi aboshiwe anciphisa umsebenzi wokwakha futhi asheshisa ukwakhiwa.
Umbuzo: Ingabe amathangi esikhungo sedatha asezingeni elifanayo?
Impendulo: Akukho thangi elilodwa elilingana nakho konke; imisebenzi yomlilo, yokugcwalisa nokubandisa icaciswa ngokwehlukana ngezinga (NFPA 22, AWWA D103-09/D100) kanye nemfuneko 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/ukuthintwa kwiphaneli yomlilo.
Mayelana ne "Water storage tanks: an integral part of the cooling process for a data centre", indlela esebenzayo iwukuthi uqale 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 impahla; ukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye neminyaka engu-10-15 yempilo yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesicaciso sakho sethangi lokupholisa lesikhungo sedatha, lokugcwalisa noma lokugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
