Ithangi Lokugcwalisa Amanzi: Umhlahlandlela Obalulekile Nezinto Eziphezulu
Ithangi lokugcwalisa amanzi libuyisela amanzi alahlekile ngenxa yokuhwamuka, ukukhukhuleka, ukukhishwa nokuvuza emigwaqweni yokupholisa kanye nemijikelezo epholile/ yenqubo, ligcina uhlelo lugcwele futhi luvikelekile. Yenza usayizi wayo kusukela ekulahlekelweni okuqhubekayo kanye nomkhawulo wokugeza kabusha nokudlulisa, futhi ucacise i-NSF/ANSI 61 (WRAS) eqinisekisiwe ye-GFS noma insimbi enamafutha e-epoxy lapho amanzi eseduze namanzi okuphuza.
Abaphathi bezikhungo zedatha abahlela amasistimu okupholisa, okuvimbela umlilo kanye namanzi enqubo babuza umbuzo oyingqayizivele: iyiphi ithangi lokugcina elidingekayo kulo msebenzi, futhi licaciswa kanjani? Lesi sihloko sigxile ku-"Ithangi Lamanzi Elengeziwe: Umhlahlandlela Obalulekile Nezinto Ezikhethwayo Eziphezulu", kuhlanganisa umhlahlandlela wokuthenga / ukuqhathanisa okukhethwayo okuphezulu. Inhloso ukunikeza onjiniyela kanye namaqembu okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olulungile, into kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Okwenziwa Ithangi Lamanzi Elengeziwe Emjikelezweni Wokupholisa / Wenqubo
· Inxephezela ukulahleka okuqhubekayo. Ukuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi kanye nokuvuza okuncane ezindaweni zokupholisa kanye nemijikelezo yamanzi abandayo kunciphisa umthamo wesistimu; ithangi lokwengeza liwubuyisela ngokuzenzakalelayo 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.
· Ukudonsa kanye nokukhipha amanzi kunezela umthwalo. Ukudonsa ngokuvamile kungu-0.001-0.005% wokugeleza; ukukhipha amanzi (ukulawula imijikelezo yokugxila) ngokuvamile kulingana nokuhwamuka okuhlukaniswe nge-(imijikelezo-1).
· Umsebenzi wokucubungula kanye nowokuphuza uyahluka. Ithangi lokugcwalisa inqubo lingaphinda londle ama-boiler, ama-humidifier noma izinto zokugeza 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 ne-epoxy-coated bolted steel zombili ziyafaneleka.
· Okuboshiwe kuqhathaniswa nokushiselwe. Ama-tanki e-GFS / epoxy aboshiwe athunyelwa ngamaphakethe 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.
· Ukupholisa izimonyo. Ukulahlekelwa okuqhubekayo kombhoshongo/umswakama wokushintsha.
· Ibhafa epholile / TES. Ukuhlukanisa nokugcina ukushisa ngesikhathi esingelona isikhathi esiphakeme.
· Inqubo kanye namanzi aphuzwayo. Ukudla kwama-boiler, ukufaka umswakama, ukuhlanza lapho izinga lihambisana khona.
Ukukhetha Nokuqhathanisa
Khetha ngezinga lamanzi, ingcindezi kanye nesidingo sokuqina kunokukhetha ngelebula. I-GFS eboshwe ngamabhawodi kanye nensimbi ene-epoxy-coated yakha ngokushesha ezindaweni eziqinile zama-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 lapho 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 amathangi e-Glass-Fused-to-Steel (GFS), i-fusion-bonded epoxy, insimbi engagqwali, insimbi egaxekile kanye namathangi ashiselwe kanye namaphahla e-aluminium geodesic dome 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 isetshenziselwe amaphrojekthi emazweni angaphezu kwe-100. Emsebenzini wokwenza izimonyo kanye nokuphuza, isitifiketi se-NSF/ANSI 61 kanye ne-WRAS yizona zinto ezinqumayo zokuhambisana, futhi amathangi e-GFS kanye namathangi aboshwe nge-epoxy-coated enkampani ayazihlangabezana nazo.
Imibuzo Evame Ukubuzwa
Umbuzo: Ithangi lamanzi okugcwalisa lenza ini ngempela ohlelweni lokupholisa?
A: Ingeza amanzi alahlekile ngenxa yokuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi kanye nokuvuza okuncane ukuze umbhoshongo wokupholisa noma iluphu epholile ingapheli amanzi. Lokho kuvikela ama-chiller nemibhoshongo ekuphazamisekeni kokugeleza okuphansi kanye nokushaqeka kokushisa ngesikhathi sokugcwalisa, ukuhlanza noma ukukhipha amanzi.
Umbuzo: Angakanani amanzi okugcwalisa umbhoshongo wokupholisa awadingayo?
Impendulo: Ukuhwamuka cishe kungu-0.8-1.6% wokujikeleza nge-10 deg F yebanga, ukukhukhuleka cishe kungu-0.001-0.005% wokugeleza, futhi ukukhishwa kwamanzi kulingana nokuhwamuka okuhlukaniswe nge-(imijikelezo yokugxila kususa u-1). Ukulahlekelwa okuqhubekayo okuphelele kanye nokuhlanza kanye nemajini yokudlulisa kusetha 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 yini enqumayo.
Umbuzo: Ingabe ithangi elilodwa lingasebenza ekuphehleni nasekugcwaliseni inqubo?
Impendulo: Kuphela uma izinga lamanzi nokwelashwa kuhambisana; izidingo zenqubo (ama-boiler, ama-humidifier, ukuhlanza) zingadinga ukulungiswa okwehlukile. Hlukanisa noma lungisa ukuze ugweme ukungcolisa iluphu yokupholisa.
Umbuzo: Yimiphi imigomo esebenza emathangini 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-"Ithangi Lokugcwalisa Amanzi: Umhlahlandlela Obalulekile Nezinto Ezinhle Kakhulu", indlela esebenzayo ukuthi 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 nento esetshenziswayo. 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 sethangi lakho lokupholisa lesikhungo sedatha, lokugcwalisa noma lokugcina ukushisa, umthamo kanye nokukhethwa kwezinto ezisetshenziswayo.
