Amathangi Amanzi Okugcwalisa Ezinqubweni Zokupholisa Nezokucubungula
Ithangi lamanzi okugcwalisa libuyisela amanzi alahlekile ngenxa yokuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi nokuvuza emibhoshongweni yokupholisa nasemijikelezweni epholile/ecubungulayo, ligcina uhlelo lugcwele futhi luvikelekile. Lilinganise ngokulahlekelwa okuqhubekayo kanye nomkhawulo wokugeza nokudlulisa, futhi ucacise i-NSF/ANSI 61 (WRAS) eqinisekisiwe ye-GFS noma insimbi enamafutha e-epoxy lapho amanzi aseduze namanzi okuphuza.
Abaqhubi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikela umlilo kanye namanzi enqubo bahlala bebuza umbuzo oyedwa ongokoqobo: iyiphi ithangi lokugcina elidingeka kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile ku-"Amathangi Amanzi Okugcwalisa Kabusha Ezinqubweni Zokupholisa Nezinqubo", ehlanganisa indima yawo kuyo yonke imigqa yokupholisa neyenqubo nokuthi ungakhetha kanjani. Inhloso ukunikeza onjiniyela kanye namaqembu okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olufanele, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Okwenziwa Ithangi Lamanzi Okugcwalisa Emjikelezweni Wokupholisa / Wokucubungula
· Linxephezela ukulahlekelwa okuqhubekayo. Ukuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi nokuvuza okuncane emibhoshongweni yokupholisa nasemijikelezweni yamanzi epholile kunciphisa umthamo wohlelo; ithangi lokugcwalisa liwubuyisela ngokuzenzakalela lisuka endaweni egciniwe eqinile.
· Ivikela ama-chiller nemibhoshongo. Ukusebenzisa i-chiller noma umbhoshongo owomile kubangela ukuphazamiseka 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.
· Ukukhukhuleka nokukhipha amanzi kunezela umthwalo. Ukukhukhuleka ngokuvamile kungu-0.001-0.005% wokugeleza; ukukhipha amanzi (ukulawula imijikelezo yokugxila) ngokuvamile kulingana nokuhwamuka okuhlukaniswe ngu-(imijikelezo-1).
· Umsebenzi wokucubungula nowokusela uyehluka. Ithangi lokugcwalisa umsebenzi lingaphinda liphekele izibasi, ama-humidifier noma ukuhlanza inqubo; ngakunye kudonsa izinga nomthamo ohlukile okufanele ithangi likwahlukanise noma likulungise.
Izinto Nemigomo Yokugcwalisa Umsebenzi
· Ukuthintana namanzi aphuzwayo kudinga isitifiketi. Lapho amanzi okugcwalisa ephuzwayo noma engena emjikelezweni oseduze namanzi aphuzwayo, cacisa amathangi aqinisekisiwe ku-NSF/ANSI 61 (kanye ne-WRAS e-UK) - i-GFS ne-epoxy-coated bolted steel zombili ziyafaneleka.
· Okuboshiwe kuqhathaniswa nokushisela. Ama-tanki e-GFS / epoxy aboshiwe athunyelwa ngamaphakethe futhi amiswa ngokushesha ezindaweni eziqinile zama-DC; insimbi eshiselwe ilungele imisebenzi emikhulu kakhulu noma enengcindezi.
· Ukulawula ukugqwala. Ukugcwalisa kwe-loop evaliwe kufanele 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/isifutho sokufaka umswakama esikhundleni salo.
· Ibhafa epholile / i-TES. Ukuhlukanisa nokugcina ukushisa okungekho esikhathini samandla aphezulu.
· Inqubo kanye namanzi aphuzwayo. Ukudla kwama-boiler, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha Nokuqhathanisa
Khetha ngezinga lamanzi, ingcindezi kanye nesidingo sokuqina kunokukhetha ngelebula. I-GFS eboshwe ngamabhawodi kanye nensimbi ene-epoxy-coated imisa ngokushesha ezindaweni eziqinile ze-DC futhi ihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi aphuzwayo; i-welded noma ukhonkolo kufaneleka izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela uma ingcindezi idlula i-atmospheric. Qinisekisa izitifiketi kanye namaphrojekthi okubhekiselwa kuwo 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 yalo yamathangi iqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi isethulwe emaphrojekhini emazweni angaphezu kwe-100. Emsebenzini wokwengeza nokuphuza, isitifiketi se-NSF/ANSI 61 kanye ne-WRAS yizona zinto ezinqumayo zokuhambisana nomthetho, futhi ama-GFS kanye namathangi aboshwe ngezibophezelo afakwe i-epoxy enkampanini ayazihlangabezana nazo.
Imibuzo Evame Ukubuzwa
Umbuzo: Ithangi lamanzi okugcwalisa lenzeni empeleni ohlelweni lokupholisa?
A: Ingeza amanzi alahlekile ngenxa yokuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi kanye nokuvuza okuncane ukuze umbhoshongo wokupholisa noma iluphu epholile ingapheli amanzi. Lokhu 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 ngo-10 deg F webanga, ukukhukhuleka cishe ku-0.001-0.005% wokugeleza, futhi ukukhishwa kwamanzi kulingana nokuhwamuka okuhlukaniswe nge-(imijikelezo yokugxila kususa u-1). Ukulahlekelwa okuqhubekayo okuphelele kanye nomkhawulo wokuhlanza nokudlulisa kubeka usayizi wethangi.
Umbuzo: Iyiphi into engcono kakhulu yethangi lamanzi okugcwalisa?
Impendulo: Lapho amanzi ephuzwayo noma eduze namanzi aphuzwayo, khetha i-NSF/ANSI 61 (kanye ne-WRAS) eqinisekisiwe ye-GFS noma i-fusion-bonded epoxy bolted steel. Kumjikelezo ovaliwe, ongaphuzwa, insimbi ene-epoxy-coated, insimbi engagqwali noma insimbi ye-galvanized ilungile.
Umbuzo: Ingabe amanzi okugcwalisa adinga isitifiketi se-NSF/ANSI 61?
A: Yebo uma ithinta amanzi aphuzwayo noma iluphu eseduze namanzi aphuzwayo - ama-GFS namathangi ane-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 ekwehliseni izinga lokushisa kanye nokwengeza inqubo?
Impendulo: Kuphela uma izinga lamanzi nokwelashwa kuhambisana; izidingo zenqubo (ama-boiler, ama-humidifier, ukugeza) zingadinga ukulungiswa okwehlukile. Hlukanisa noma lungisa ukuze ugweme ukungcolisa iluphu yokupholisa.
Umbuzo: Yimiphi imigomo esebenzayo 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.
Nge-"Makeup Water Tanks for Cooling and Process Systems", 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 kanye nempahla. Ukugcinwa kwamanzi esikhungweni sedatha yisinqumo sezinhlelo, hhayi ukuthenga impahla; ukucacisa kahle ekuqaleni 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.
