Ithangi Lensimbi Lamanzi: Ukwakhiwa Kwe-Bolted vs. Welded KokuGcina Amanzi Isikhathi Eside
Insimbi iyinto eyisisekelo yokwakha yokugcina amanzi, kodwa indlela insimbi eba ngayo ithangi — nge-bolts noma nge-welding — ishintsha konke mayelana nokuvikelwa kokugqwala, ukufakwa, nokunakekelwa kwesikhathi esizayo.
Ithangi lensimbi lamanzi umkhumbi wensimbi oshiselwe noma oboshelwe ndawonye owenzelwe i-AWWA D103 ukuze uthole amanzi okuphuza, amanzi okucubungula noma amanzi okucisha umlilo. Amathangi aboshelwe asebenzisa amaphaneli aqoshwe efekthri ahlanganiswa endaweni yokusebenza ngaphandle kokushisela; amathangi ashiselwe akhiwa endaweni yokusebenza futhi aqoshwe ngemva kokumiswa, ngendlela ngayinye ethwala imiphumela ehlukile yokugqwala nokulawula ikhwalithi.
Yiziphi Izindlela Ezimbili Zokwakha Zamathangi Ensimbi Amanzi?
Amathangi ensimbi aboshelwe: amaphaneli agxivizwa, aqoshwe futhi aphiliswe efeKthri, bese eboshelwa ndawonye endaweni yokusebenza ngemihlangano evaliwe. Akukho msebenzi oshisayo, ukugqoka okungaguquki, futhi kulula ukuwandisa noma ukuhambisa.
Amathangi ensimbi ashiselwe: amapuleti ashiselwa endaweni yokusebenza abe umzimba oqhubekayo, bese egqokwa. Aqinile futhi ayinto eyodwa, kodwa ukufaka ukugqoka nokuhlola kwenzeka ezimweni zasendle.
Ubuqotho bokugqoka yikhona okuhlukanisayo: i-enamel efakwe efeKthri (GFS) isetshenziswa ku-820–930°C ezimweni ezilawulwayo, kuyilapho amathangi ashiselwe encika ekugqokeni okufakwa endaweni yokusebenza okunzima ukuqinisekisa nokukulungisa.
Amazinga: I-AWWA D103 ilawula amathangi ensimbi abhuntshisiwe asebenza nge-factory; amathangi a-weldwe endaweni ngokuvamile alandela i-API 650 noma i-AWWA D100, ngezindlela ezahlukene zokuhlola.
Zihluka Kanjani Izinhlelo Zokuvikela Ukugqwala?
I-GFS enamel: ingilazi ehlanganiswe nensimbi ekushiseni okuphezulu inikeza indawo engasebenzi, engenazimbotshana ene-pH 1–14, ihlolwe nge-holiday nge-1500V DC — okuwubufakazi obuphezulu kakhulu oburekhodiwe bokuqina kokumboza.
Ukufakwa kwe-zinc: i-zinc eshisayo ivikela insimbi ngokuyinikela futhi ilungele umsebenzi owomile noma onokugqwala okuncane, kodwa ukuvikelwa kwe-zinc nokunakekela emaphethelweni asikiwe kunezidingo ezengeziwe zokulungisa.
Insimbi engagqwali: ukumelana nokugqwala okususelwa kuma-alloy ngaphandle kokupendwa, kodwa ngezindleko eziphakeme kakhulu zempahla, isetshenziswa kakhulu emisebenzini ekhethekile noma yokudla.
I-epoxy efakwa endaweni: iyindinganiso yamathangi ahlanganisiwe; ukusebenza kuncike ekulungiseleleni indawo, ukulawulwa komswakama, nekhono lomfaki endaweni yomsebenzi.
Yiliphi Ithangi Lamanzi Lensimbi Okufanele Ulikhethe?
Okwamanzi okuphuza: i-GFS ehlanganisiwe eno-NSF/ANSI 61 enamel eqinisekisiwe iyindlela efakazelwe yokuthola amanzi ahlanzekile nokugcinwa okuphansi iminyaka engu-30–40.
Kumaphrojekthi amakhulu noma asheshayo: amathangi a-bolted afakwa ngezinsuku kuya emavikini uma kuqhathaniswa nezinyanga kuma-welded — umehluko obalulekile kokuphakelwa kwesizini noma okuphuthumayo.
Kokuthutha noma kokwandisa: amathangi a-bolted kuphela angahlakazwa, athuthwe, futhi aphinde amiswe, evikela imali enkulu uma izindawo zishintsha.
Kosayizi abakhulu kakhulu: a-welded noma akhonkolo angafanele imikhumbi emikhulu kakhulu eyodwa, kuyilapho amathangi a-bolted ehlangana abe amasistimu amaningi adlula 60,000 m³.

Isinqumo sethangi lensimbi yamanzi empeleni isinqumo sokunamathisela nokuthutha: i-GFS enamel ehlanganiswe efektri, ukuhlanganiswa ngamabhawodi kanye nobunjiniyela be-AWWA D103 kunikeza inhlanganisela engcono kakhulu yekhwalithi yamanzi, isivinini kanye nezindleko zeminyaka engu-30 kumaphrojekthi amaningi.
Imibuzo Ejwayelekile (FAQ)
Umbuzo 1: Umehluko phakathi kwamathangi ensimbi aboshwe ngamabhawodi nalawo ashiselwe ndawonye?
Amathangi aboshwe ngamabhawodi asebenzisa amaphaneli ahlanganiswe efektri ahlanganiswe ngamabhawodi kanye nokuvuleka okuvalwe kahle — akukho ukushisela endaweni, ukumiswa okusheshayo kanye nokunamathisela okungaguquki. Amathangi ashiselwe ahlanganiswa endaweni bese enamatheliswa, okuqinisa ngokwesakhiwo kodwa kungaba nengozi yokonakala kokunamathisela kanye neshejuli ehamba kancane.
Umbuzo 2: Iyiphi ithangi lensimbi engcono kakhulu yamanzi okuphuza?
Ithangi lensimbi elihlanganisiwe le-GFS elino-NSF/ANSI 61 enamel eqinisekisiwe liwukukhetha okuhamba phambili: indawo yengilazi encibilikisiwe igcina amanzi ehlanzekile, imelana nokugqwala iminyaka engu-30–40 futhi ayidingi ukupendwa endaweni.
UMBUZO 3: Ithangi lamanzi lensimbi lihlala isikhathi esingakanani?
Amathangi ensimbi e-GFS ahlanganisiwe enzelwe iminyaka engu-30–40. Insimbi ependiwe ehlanganisiwe ngokuvamile idinga ukuphinde ipendwe njalo eminyakeni engu-8–12, kuyilapho insimbi ye-galvanized ihlala iminyaka engu-15–25 kuye ngamakhemikhali amanzi.
UMBUZO 4: Ingabe ithangi lensimbi elihlanganisiwe linganwetshwa kamuva?
Yebo. Ukwakhiwa ngamabhawodi kuvumela ukwengeza amarings ukuze kukhuphuke ukuphakama noma ukuhlanganisa amathangi engeziwe — ukuguquguquka okungakwazi ukunikezwa amathangi a-welded noma akhonkolo ngaphandle kokudilizwa.
