Amathangi Amanzi Ensipho Axhunywe Ngezikulufu Agqinswe Ngengilazi: Izinga Legolide Lemisebenzi Yamanzi
Emkhakheni wezobunjiniyela bomphakathi nokwelashwa kwamanzi, isitsha sokugcina siyinhliziyo yesistimu. Amathangi ensimbi ahlanganiswe ngezingilazi, aziwa ngokobuchwepheshe ngokuthi i-Glass-Fused-to-Steel (GFS), avele njengesixazululo esikhethwa yimboni sokugcina amanzi angcolile omphakathi, amanzi okuphuza, nawemboni. Ngokuhlanganisa amandla esakhiwo ensimbi enamandla aphezulu nokungathathi hlangothi kwamakhemikhali kwengilazi, la mathangi ahlinzeka ngempilo ende engenakuqhathaniswa, aqeda izinkinga zokulungisa ezivame ukuphindaphindeka ezihambisana ne-concrete yakudala noma insimbi eyenziwe ensimini.
1. Ubuchwepheshe: Ingilazi-Eqiniswe-kuya-ku-ensimbi (GFS)
Ukuqina kwamathangi e-GFS kuvela enqubeni yokushisa eziko yezimboni. Ngokungafani nezingubo ze-epoxy ezisetshenziswa ensimini ezingakwazi ukuhlukana, amaphaneli e-GFS adalwa efektri ngaphansi kwezimo ezilawulwa kakhulu.
● Inqubo: Amashidi ensimbi aphezulu agqinswa ngesihlabathi, agqinswe nge-glass-enamel frit, futhi ashunqulwe ezingeni lokushisa elisuka ku-820°C kuye ku-930°C.
● Isibopho: Ingilazi ihlangana nensimbi ezingeni le-molecular, idala isibopho samakhemikhali esiqine kakhulu futhi esingasebenzi.
● Umphumela: Indawo engakwazi ukuklwebheka, engenawo umoya, engangenwa ngumnyombo nomhlwa, iqinisekisa ukuhlanzeka kwamanzi futhi ivimbela ukungcola kwezinto eziphilayo.
2. Izinzuzo Zamasu
Amaqembu ezobunjiniyela nabaphathi bezindawo bakhetha amathangi e-GFS ngoba axazulula amaphuzu abalulekile okuhluleka kwengqalasizinda yokugcina amanzi:
● Akukho Ukugcinwa: Ngoba ingaphakathi lengilazi lingasebenzi, lawa mathangi akadingi ukuhlanzwa ngesihlabathi noma ukugcotshwa kabusha, kuqeda izindleko eziphezulu zokugcinwa kwempilo yonke.
● Ukwakhiwa Okusezingeni Eliphezulu: Amaphaneli ahlangene ngama-bolt endaweni, okunciphisa kakhulu izikhathi zokwakha futhi kuqede isidingo sokusebenza okuyingozi "okushisayo" (ukushisela) eduze kwemishini yokwelapha amanzi.
● Ukuhlukahluka Kwamakhemikhali: Ubuso obuglasi buhambisana nebanga elibanzi le-pH (ngokuvamile 1-14), okwenza bube nezinga eliphezulu kusuka emanzini okuphuza ahlanzekile kuya kudoti kamasipala onolaka kanye nemfucuza yezimboni.
● Ukusimama: Amathangi e-GFS akhiwe ngendlela efanayo, okusho ukuthi angahlukaniswa, athuthukiswe, noma andiswe uma izidingo zesikhungo zishintsha ngokuhamba kwesikhathi.
3. Izindinganiso Zokuhambisana Nobunjiniyela
Ukuqinisekisa ubuqotho bokwakhiwa nokusebenza, gcizelela ukuthi amathangi akho e-GFS ahlangabezana nezindinganiso ezilandelayo ezamukelwa umhlaba wonke:
● AWWA D103-19: Izinga le-American Water Works Association lamathangi ensimbi axhunywe ngezikulufu.
● ISO 28765: Izinga lamazwe omhlaba lokugqoka ingilazi ne-porcelain enamel kumathangi ensimbi axhunywe ngezikulufu.
● NSF/ANSI 61: Kuyimpoqo kumathangi agcina amanzi okuphuza (okunempilo), aqinisekisa ukuthi izinto azikhiphi izinto ezingcolisa amanzi.
4. Ukuhlaziywa Okuhambisanayo: Izixazululo Zamathangi Okugcina
I-Engineering Metric | I-Glass-Lined (GFS) Bolted | I-Field-Welded Carbon Steel | Ukhonkolo Oluqinisiwe |
Ukugqoka Kwangaphakathi | Ingilazi Eqiniswe (Engasebenzi) | I-Liquid Epoxy (Idinga Ukuphinda Ugqoke) | Akukho (Okungena Umoya/Okugcotshiwe) |
Ukugcinwa | Okuncane | Okuphezulu (Ukudubula Ngezikhathi Ezithile) | Phezulu (Ukuvalwa Kwezikhala) |
Isikhathi Sokufakwa | Ngokushesha (Amaviki) | Phakathi (Izinyanga) | Kancane (Izinyanga/Ukuqina) |
Ingozi Yesayithi | Phansi (Akukho Ukushisela) | Phezulu (Umsebenzi Oshisayo) | Phakathi |
Impilo Yesevisi | Iminyaka engu-30+ | Iminyaka engu-15–20 | Iminyaka engu-10–20 |
5. Uhlu Lokuhlola Lokuthenga Nokucaciswa
Lapho ubhala izicelo zakho ze-RFP zesitoreji samanzi, faka lezi zinto ezibalulekile ukuze uqinisekise ukuthi uthola uhlelo lwe-GFS olusezingeni eliphezulu:
1. Ukuhlolwa Kwamaholide: Cela ukuhlolwa okuphelele kwe-spark kagesi kuwo wonke amaphaneli angaphakathi ngaphambi kokuthunyelwa ukuze kuqinisekiswe ukugqoka okungenazimbobo.
2. Ubuqotho Bokwakhiwa: Qinisekisa ukuthi izibalo zenziwa ngemithwalo yomoya, ikhephu, kanye ne-seismic eyenzelwe indawo ethile ngokusekelwe kumakhodi wokwakha endawo.
3. Izinhlelo Zokubopha: Qinisekisa ukusetshenziswa kwezinto zokubopha ezisezingeni eliphezulu, eziqinisekisiwe yi-NSF-61 (ngokuvamile ezi-EPDM noma ezi-silicone) ezikwazi ukugcina ubopho olungangeni manzi emashumini eminyaka okwandiswa/ukuncipha kwezinga lokushisa.
4. Izesekeli: Cacisa izesekeli ezihambisana nezimfuneko, okuhlanganisa amapuleti angama-anti-vortex, izitebhisi zangaphakathi, nezinkomba zamanzi ezilinganisiwe.
