Ithangi lamanzi okugcwalisa uhlelo lwamanzi apholile
Ithangi lamanzi okugcwalisa libuyisela amanzi alahlekile ngenxa yokuhwamuka, ukugudluka, ukukhishwa kwamanzi nokuvuza emibhoshongweni yokupholisa nasemijikelezweni epholile/ yenqubo, ligcine uhlelo lugcwele futhi luvikelekile. Lilinganise ngokulahlekelwa okuqhubekayo kanye nomkhawulo wokugeza nokudlulisa, futhi ucacise i-NSF/ANSI 61 (WRAS) eqinisekisiwe ye-GFS noma insimbi eboywe nge-epoxy lapho amanzi aseduze namanzi okuphuza.
Abaphathi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikela umlilo kanye namanzi enqubo babuza umbuzo owodwa ongokoqobo: yiliphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Lesi sihloko sigxile ku-\"Ithangi lamanzi elengezayo lesistimu yamanzi abandayo\", futhi sihlanganisa ukwengezwa kwamanzi kumjikelezo wamanzi abandayo. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olulungile, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Okwenziwa Ithangi Lamanzi Elengezayo Kumjikelezo Wokupholisa / Wenqubo
· Kunxephezela ukulahleka okuqhubekayo. Ukuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi kanye nokuvuza okuncane ezindaweni zokupholisa kanye nemijikelezo yamanzi abandayo kunciphisa umthamo wesistimu; ithangi lamanzi elengezayo liwubuyisela ngokuzenzakalela lisuka endaweni yokugcina eqinile.
· Ivikela ama-chiller nemibhoshongo. Ukusebenzisa i-chiller noma umbhoshongo owomile kubangela ukuphuma kokugeleza okuphansi kanye nokushaqeka kokushisa; isitoreji sokugcwalisa sigcina 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 kanye nokukhipha amanzi kunezela umthwalo. Ukudonsa ngokuvamile kungu-0.001-0.005% wokugeleza; ukukhipha amanzi (ukulawula imijikelezo yokugxila) ngokuvamile kulingana nokuhwamuka okuhlukaniswe ngu-(imijikelezo-1).
· Umsebenzi wokucubungula kanye namanzi aphuzwayo kuyahluka. Ithangi lokugcwalisa umsebenzi lingaphinda londle ama-boiler, ama-humidifier noma ukuhlanza inqubo; ngakunye kudonsa izinga elihlukile nomthamo okufanele ithangi lihlukanise noma lilungise.
Izinto kanye Namazinga Omsebenzi 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 zombili ziyafaneleka.
· Okuboshiwe kuqhathaniswa nokushiselwe. Amathangi e-GFS / epoxy aboshiwe athunyelwa ngamazinga futhi amiswa ngokushesha ezindaweni eziqinile ze-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.
· Ukwenza izimonyo okupholile. Ukulahlekelwa okuqhubekayo kombhoshongo/isifudumezi esishintshwayo.
· Isibambi esipholile / i-TES. Ukuhlukanisa nokugcina ukushisa ngesikhathi esingasetshenziswa kakhulu.
· Inqubo kanye namanzi aphuzwayo. Ukudla kwama-boiler, ukufuma, ukugeza lapho izinga lihambisana khona.
Ukukhetha Nokuqhathanisa
Khetha ngezinga lamanzi, ingcindezi kanye nesidingo sokuqina kunokukhetha ngelebula. I-GFS eboshiwe kanye nensimbi ene-epoxy-coated yakha ngokushesha ezindaweni eziqinile zama-DC futhi ihlangabezana ne-NSF/ANSI 61 emsebenzini oseduze namanzi aphuzwayo; insimbi eshiselwe noma ukhonkolo kulungele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umoya osemkhathini. Qinisekisa izitifiketi kanye namaphrojekthi okubhekiselwa kuwo ngaphambi kokunikeza umsebenzi.

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 egcotshwe nge-zinc kanye namathangi ashiselwe kanye namaphahla e-aluminium geodesic dome kanye nemikhumbi yengcindezi ye-ASME. Imikhiqizo yamathangi ayo iqinisekiswa nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi isetshenziselwe amaphrojekthi emazweni angaphezu kwe-100. Emsebenzini wokuhlobisa kanye nokuphuza, ukuqinisekiswa kwe-NSF/ANSI 61 kanye ne-WRAS yizindawo zokuthobela ezinqumayo, futhi ama-GFS kanye namathangi aboshwe ngezibophezelo afakwe i-epoxy enkampanini ayazihlangabezana nazo.
Imibuzo Evame Ukubuzwa
Umbuzo: Ithangi lamanzi okugcwalisa lenzeni ngempela ohlelweni lokupholisa?
A: Kufaka esikhundleni samanzi alahlekile ekuhwameni, ekugudlukeni, ekukhishweni nokuvuza okuncane ukuze umbhoshongo wokupholisa noma iluphu ebandayo ingeke iphele amanzi. Lokhu kuvikela ama-chiller nemibhoshongo ekuphumeni kwamanzi aphansi kanye nokushaqeka kokushisa ngesikhathi sokugcwalisa, ukuhlanza noma ukukhipha amanzi.
U: Amanzi amangaki okugcwalisa adingwa umbhoshongo wokupholisa?
A: Ukuhwama cishe kungu-0.8-1.6% wokujikeleza ngo-10 deg F webanga, ukugudluka cishe kungu-0.001-0.005% wokugeleza, futhi ukukhishwa kwamanzi kulingana nokuhwama 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. Emjikelezweni ovaliwe, ongaphuzwa, i-epoxy-coated, insimbi engagqwali noma i-galvanized steel 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 nalawo ane-epoxy-coated angahlangabezana ne-NSF/ANSI 61. Amanzi enqubo evaliweyo emsulwa ngaphandle kokuthintana namanzi aphuzwayo awadingi ngokuqinile lokho, kodwa umcacisi kanye nekhodi yendawo yenza isinqumo.
Umbuzo: Ingabe ithangi elilodwa lingasebenza ekuphehleni nasekwenzeni amanzi okusetshenziswa enqubeni?
Impendulo: Kuphela uma izinga lamanzi nokwelashwa kuhambisana; izidingo zenqubo (ama-boiler, ama-humidifier, ukugeza) zingase zidinge 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 (ishiselwe); 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 "Ithangi lamanzi okugcwalisa uhlelo lwamanzi abandayo", indlela esebenzayo ukuqala emsebenzini - ikhwalithi yamanzi, ingcindezi, umthamo kanye nesidingo sokuqina - bese uvumela umgomo (NFPA 22, AWWA D103-09/D100, ASME BPVC VIII, NSF/ANSI 61) unqume uhlobo lwethangi nempahla. Ukugcinwa kwamanzi esikhungweni sedatha yisinqumo sezinhlelo, hhayi ukuthenga impahla; ukucacisa kahle kusukela 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.
