Kwadalwa ngo Ngokwamukisa
Ungayilinganisa kanjani ithangi lamanzi okugcwalisa umbhoshongo wokupholisa?
Ithangi lamanzi okugcwalisa libuyisela amanzi alahlekile ngenxa yokuhwamuka, ukukhukhuleka, ukukhishwa kanye nokuvuza emibhoshongweni yokupholisa kanye nemijikelezo epholile/ yenqubo, ligcina uhlelo lugcwele futhi luvikelekile. Yilinganise ngokulahlekelwa okuqhubekayo kanye nomkhawulo wokugeza kanye nokudlulisa, futhi ucacise i-NSF/ANSI 61 (WRAS) eqinisekisiwe ye-GFS noma insimbi ehlanganiswe ne-epoxy lapho amanzi eseduze namanzi okuphuza.
Abasebenzi bezikhungo zedatha abahlela amasistimu okupholisa, okuvimbela umlilo kanye namanzi enqubo baye babuze umbuzo owodwa ongokoqobo: yiliphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Lesi sihloko sigxile ku-"Ungayilinganisa Kanjani Ithangi Lamanzi Elengezelayo E-Cooling Tower?", sihlanganisa indlela yokulinganisa yokwengeza amanzi e-cooling-tower. Inhloso ukunikeza onjiniyela kanye namaqembu okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olufanele, into kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Ithangi Lamanzi Elengezelayo Lenzani Ku-Cooling / Process Loop
· Linxephezela ukulahleka okuqhubekayo. Ukuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi kanye nokuvuza okuncane kuma-cooling tower kanye nama-chilled-water loop kunciphisa umthamo wesistimu; ithangi lokwengeza liwubuyisela ngokuzenzakalela lisuka endaweni yokugcina ezinzile.
· Ivikela ama-chiller kanye nemibhoshongo. Ukusebenzisa i-chiller noma umbhoshongo owomile kubangela ukuphuma kokugeleza okuphansi kanye nokushaqeka kokushisa; isitoreji sokugcwalisa sisiza ukugcina umjikelezo ugcwele ngesikhathi sokugcwalisa, ukuhlanza isihlungi kanye nokukhipha amanzi okujwayelekile.
· Ihlukanisa ukunikezwa kwamanzi nesidingo. Ukunikezwa kwamanzi kamasipala noma komthombo kungase kube ngezikhathi noma kube nengcindezi elinganiselwe; ithangi ligcina lokho kuguquguquka ukuze ukupholisa kungami ngenxa yenkinga yokunikezwa kwamanzi.
Imithombo Yokulahlekelwa Kanye Nezinombolo Ezingemuva Kokulinganisa Usayizi
· Ukuhwamuka kwamanzi kuyabusa. Imibhoshongo evulekile yokupholisa ilahlekelwa cishe u-0.8-1.6% wokujikeleza nge-10 deg F (5.5 deg C) yebanga; lokhu kuyisisekelo okufanele uhlelo lokugcwalisa lusibuyisele.
· Ukudonsa nokukhipha amanzi kwengeza umthwalo. Ukudonsa ngokuvamile kungu-0.001-0.005% wokugeleza; ukukhipha amanzi (ukulawula imijikelezo yokugxila) ngokuvamile kulingana nokuhwamuka okuhlukaniswe ngu-(imijikelezo-1).
· Umsebenzi wokucubungula nowokuphuza uyehluka. Ithangi lokugcwalisa inqubo lingaphinda londle ama-boiler, ama-humidifier noma ukuhlanza inqubo; ngakunye kudonsa izinga nomthamo ohlukile okufanele ithangi likwahlukanise noma likulungiselele.
Izinto Nemigomo Yomsebenzi Wokugcwalisa
· Ukuthintana namanzi aphuzwayo kudinga isitifiketi. Lapho amanzi okugcwalisa ephuzwayo noma engena kumjikelezo oseduze namanzi aphuzwayo, cacisa amathangi anesitifiketi se-NSF/ANSI 61 (kanye ne-WRAS e-UK) - i-GFS kanye nensimbi eboshiwe ene-epoxy coating zombili ziyafaneleka.
· Okuboshiwe kuqhathaniswa nokushiselwe. Ama-tanki e-GFS / epoxy aboshiwe athunyelwa ngamaphakethe futhi amiswa ngokushesha ezindaweni eziqinile zama-DC; insimbi eshiselwe ilungele imisebenzi emikhulu kakhulu noma enengcindezi.
· Ukulawulwa kokugqwala. Ukugcwalisa kwe-loop evaliwe kusafanele kugweme ukuthathwa kwensimbi; ama-trim ahlanganisiwe noma angenasici kanye nemininingwane ye-cathodic/liner kugcina izinga lamanzi lizinzile.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. I-NFPA 22 igcinwe ihlukile emanzini enqubo.
· Ukupholisa izimonyo. Ukulahlekelwa okuqhubekayo kombhoshongo/ humidifier ukushintshwa.
· Ibhafa epholile / TES. Ukuhlukanisa kanye nokugcina ukushisa okungekho ngesikhathi esiphakeme.
· Inqubo kanye namanzi aphuzwayo. Ukudla kwama-boiler, ukufuma, ukugeza lapho izinga lihambisana.
Ukukhetha nokuQhathanisa
Khetha ngezinga lamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS eboshiwe kanye nensimbi e-epoxy-coated yakha ngokushesha ezindaweni eziqinile ze-DC futhi ihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi aphuzwayo; i-welded noma ukhonkolo kulungele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela uma ingcindezi idlula i-atmospheric. Qinisekisa izitifiketi kanye namaphrojekthi abekiwe ngaphambi kokunikeza.

Ubungcweti Benkampani
I-Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.), umkhiqizi wamathangi okugcina izinto aboshwe ngezibophezelo futhi ashiselwe, owasungulwa ngo-2008, ukhiqiza ama-Glass-Fused-to-Steel (GFS), i-fusion-bonded epoxy, insimbi engagqwali, insimbi egcwele i-zinc kanye namathangi ashiselwe kanye namaphahla e-aluminium geodesic dome kanye ne-ASME pressure vessels. Imikhiqizo yamathangi ayo iqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi isetshenziselwe amaphrojekthi emazweni angaphezu kwe-100. Emsebenzini wokwenza izimonyo kanye nokuphuza, ukugunyazwa kwe-NSF/ANSI 61 kanye ne-WRAS yizona zinto ezinqumayo zokuhambisana nomthetho, futhi ama-GFS kanye namathangi aboshwe ngezibophezelo afakwe i-epoxy enkampanini ayazihlangabezela.
Imibuzo Evame Ukubuzwa
Umbuzo: Ithangi lamanzi okugcwalisa lenzeni ngempela ohlelweni lokupholisa?
A: Ingeza esikhundleni samanzi alahlekile ekuhwamukeni, ekukhuphukeni, ekukhishweni nasekuvuzeni okuncane ukuze umbhoshongo wokupholisa noma iluphu epholile ingeke iphele amanzi. Lokho kuvikela ama-chiller nemibhoshongo ekuphazamisekeni kokugeleza okuphansi kanye nokushaqeka kokushisa ngesikhathi sokugcwalisa, ukuhlanza noma ukukhipha amanzi.
U: Amanzi amangaki okugcwalisa adingwa umbhoshongo wokupholisa?
A: Ukuhwamuka cishe ku-0.8-1.6% wokujikeleza nge-10 deg F yebanga, ukukhuphuka cishe ku-0.001-0.005% wokugeleza, futhi ukukhishwa kulingana nokuhwamuka okuhlukaniswe nge-(imijikelezo yokugxila kususa u-1). Ukulahlekelwa okuqhubekayo okuphelele kanye nokuhlanza nokudlulisela umkhawulo kumisa usayizi wetanki.
Umbuzo: Iyiphi into engcono kakhulu yethangi lamanzi okugcwalisa?
Impendulo: Lapho amanzi ephuzwayo noma eduze namanzi aphuzwayo, khetha i-GFS eqinisekisiwe ye-NSF/ANSI 61 (kanye ne-WRAS) noma insimbi ehlanganisiwe ye-epoxy eboshwe ngamabhawodi. Kumjikelezo ovaliwe, ongaphuzwa, insimbi ehlanganiswe nge-epoxy, insimbi engagqwali noma insimbi egcwele i-zinc ilungile.
Umbuzo: Ingabe amanzi okugcwalisa adinga isitifiketi se-NSF/ANSI 61?
A: Yebo uma ithinta amanzi aphuzwayo noma iluphu eseduze namanzi aphuzwayo - amathangi e-GFS kanye ne-epoxy-coated angahlangabezana ne-NSF/ANSI 61. Amanzi e-closed-loop process angenalo ukuxhumana namanzi aphuzwayo awadingi ngokuqinile, kodwa umchazi kanye nekhodi yendawo yenza isinqumo.
Umbuzo: Ingabe ithangi elilodwa lingasebenza ekuphehleni nasekwenzeni i-process makeup?
Impendulo: Kuphela uma izinga lamanzi nokwelashwa kuhambisana; izinto ezisetshenziswayo (ama-boiler, ama-humidifier, ukugeza) zingadinga ukulungiswa okuhlukile. Hlukanisa noma lungisa ukuze ugweme ukungcolisa iluphu yokupholisa.
Umbuzo: Yimiphi imigomo esebenza kumathangi amanzi okugcwalisa?
Impendulo: Isakhiwo silandela i-AWWA D103-09 (insimbi eboshiwe) noma i-AWWA D100 (insimbi eshiselwe); ukuthintana namanzi aphuzwayo kunezela i-NSF/ANSI 61 ne-WRAS; ukwakhiwa kwesakhiwo kunezela i-EN 1090/CE; ikhwalithi/ukuphepha kuvela ku-ISO 9001/45001.
Ku-"Ungayilinganisa Kanjani Ithangi Lamanzi Okugcwalisa Lesihlahla Sokwehlisa Izinga Lokushisa?", indlela esebenzayo ukuqala 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 nempahla. Ukugcinwa kwamanzi esikhungweni sedatha yisinqumo sezinhlelo, hhayi ukuthenga okuvamile; ukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesicaciso sakho sethangi lokupholisa lesikhungo sedatha, lokugcwalisa noma lokugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
