Amathangi Amanzi Okugcwalisa: Umhlahlandlela Wezobuchwepheshe Ngendima, Usayizi, Izinto Zokwakha, kanye Namazinga
Ithangi lamanzi okugcwalisa libuyisela amanzi alahlekile ngenxa yokuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi nokuvuza emibhoshongweni yokupholisa kanye nemijikelezo epholile/yenqubo, ligcina uhlelo lugcwele futhi luvikelekile. Yenza usayizi wayo kusukela ekulahlekelweni okuqhubekayo kanye nomkhawulo wokugeza nokudlulisa, futhi ucacise i-NSF/ANSI 61 (WRAS) eqinisekisiwe ye-GFS noma insimbi enamafutha e-epoxy lapho amanzi eseduze namanzi okuphuza.
Abasebenzi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikela umlilo kanye namanzi enqubo baye babuze umbuzo owodwa ongokoqobo: yiliphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Lesi sihloko sigxile ku-"Amathangi Amanzi Okugcwalisa", sihlanganisa incazelo kanye nokubuka konke. 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 Yithangi Lamanzi Okugcwalisa Emjikelezweni Wokupholisa / Wenqubo
· Kubuyisela ukulahleka okuqhubekayo. Ukuhwamuka, ukukhukhuleka, ukukhishwa kwamanzi kanye nokuvuza okuncane ezindaweni zokupholisa kanye nemijikelezo yamanzi abandayo kunciphisa umthamo wesistimu; ithangi lokugcwalisa liwubuyisela ngokuzenzakalela lisuka endaweni egciniwe eqinile.
· Kuvikela ama-chiller kanye nemibhoshongo. Ukusebenza kwe-chiller noma umbhoshongo owomile kubangela ukuphazamiseka kokugeleza okuphansi kanye nokushaqeka kokushisa; indawo yokugcina yokugcwalisa igcina umjikelezo ugcwele ngesikhathi sokugcwalisa, ukuhlanza isihlungi kanye nokukhipha amanzi okujwayelekile.
· Kuhlukanisa ukuhlinzeka nokufunwa. Ukuhlinzeka kukamasipala noma komthombo kungase kube ngezikhathi noma kukhawulelwe ingcindezi; ithangi ligcina lokho kuguquguquka ukuze ukupholisa kungami ngenxa yokuphazamiseka kokuhlinzeka.
Imithombo Yokulahlekelwa Nezinombolo Ezingemuva Kokulinganisa
· Ukuhwamuka kuyabusa. Imibhoshongo yokupholisa evulekile ilahlekelwa cishe u-0.8-1.6% wokujikeleza ngo-10 deg F (5.5 deg C) webanga; 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 uyahluka. Ithangi lokugcwalisa inqubo lingaphinda londle ama-boiler, ama-humidifier noma izinto zokugeza inqubo; ngayinye idonsa 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 aqinisekisiwe ku-NSF/ANSI 61 (kanye ne-WRAS e-UK) - i-GFS kanye nensimbi eboshiwe ene-epoxy coating zombili ziyafaneleka.
· Okuboshiwe ngamabhawudi kuqhathaniswa nokushisela. Amathangi e-GFS / epoxy aboshiwe ngamabhawudi athunyelwa ngamazinga futhi amiswa ngokushesha ezindaweni eziqinile ze-DC; insimbi eshiselwe ilungele imisebenzi emikhulu kakhulu noma enengcindezi.
· Ukulawula ukugqwala. Ukwenziwa kabusha kwe-closed-loop 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/isifutho sokushintsha.
· Ibhafa epholile / TES. Ukwehlukanisa nokugcina ukushisa okungekho esikhathini esiphakeme.
· Ukucubungula namanzi aphuzwayo. Ukuphakela kubhayela, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha Nokuqhathanisa
Khetha ngezinga lamanzi, ingcindezi kanye nesidingo sokuqina kunokukhetha ngelebula. I-GFS eboshiwe kanye nensimbi ehlanganiswe nge-epoxy yakha ngokushesha ezindaweni eziqinile ze-DC futhi ihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi aphuzwayo; insimbi eshiselwe noma ukhonkolo ilungele izidingo ezinkulu kakhulu noma ezinengcindezi; izitsha ze-ASME zisebenza kuphela lapho ingcindezi idlula umoya. Qinisekisa izitifiketi kanye namaphrojekthi okubhekiselwe 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 yamathangi ayo iqinisekiswa nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi isetshenzisiwe emisebenzini engaphezu kwezindawo eziyi-100. Emsebenzini wokwenza izinto zokuthambisa kanye nokuphuza, isiqinisekiso se-NSF/ANSI 61 kanye ne-WRAS yizona zinto ezibalulekile zokuhambisana nomthetho, futhi ama-GFS kanye namathangi aboshwe ngezibophezelo afakwe i-epoxy enkampanini ayazihlangabezana nazo.
Imibuzo Evame Ukubuzwa
Umbuzo: Ithangi lamanzi okugcwalisa lenza ini ngempela ohlelweni lokupholisa?
A: Ingeza esikhundleni samanzi alahlekile ngenxa yokuhwamuka, ukusabalala, ukukhishwa kwamanzi angcolile kanye nokuvuza okuncane ukuze umbhoshongo wokupholisa noma iluphu epholile ingeke iphele amanzi. Lokho kuvikela ama-chiller nemibhoshongo ekuphumeni kwamanzi aphansi kanye nokushaqeka kokushisa ngesikhathi sokugcwalisa, ukuhlanza noma ukukhipha amanzi.
U: Amanzi angakanani okwenziwa kabusha adingwa umbhoshongo wokupholisa?
A: Ukuhwamuka cishe kungu-0.8-1.6% wokujikeleza ngo-10 deg F webanga, ukusabalala cishe kungu-0.001-0.005% wokugeleza, futhi ukukhishwa kwamanzi angcolile 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, i-epoxy-coated, insimbi engagqwali noma ye-galvanized ilungile.
Umbuzo: Ingabe amanzi okugcwalisa adinga isitifiketi se-NSF/ANSI 61?
Impendulo: Yebo uma ethinta amanzi aphuzwayo noma umjikelezo oseduze namanzi aphuzwayo - amathangi e-GFS ne-epoxy-coated angahlangabezana ne-NSF/ANSI 61. Amanzi enqubo yomjikelezo ovaliwe kuphela ngaphandle kokuthinta amanzi aphuzwayo awadingi ngokuqinile, kodwa umchazi kanye nekhodi yendawo kuyanquma.
Umbuzo: Ingabe ithangi elilodwa lingasebenza ekupholiseni nasekugcwaliseni inqubo?
Impendulo: Kuphela uma izinga lamanzi nokwelashwa kuhambisana; izidingo zenqubo (amabhayela, izifakamswakama, ukugeza) zingase zidinge ukulungiswa okwehlukile. Hlukanisa noma lungisa ukuze ugweme ukungcolisa umjikelezo wokupholisa.
Umbuzo: Yimaphi amazinga asebenza kumathangi amanzi okugcwalisa?
A: 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.
Kuma-"Makeup Water Tanks", indlela esebenzayo ukuqala emsebenzini - ikhwalithi yamanzi, 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 ekuqaleni kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze nixoxe ngezinhlelo zakho zokupholisa zesikhungo sedatha, ithangi lokugcwalisa noma lokugcina ukushisa, umthamo kanye nokukhethwa kwezinto.
