umenzi wethangi lamanzi lesikhungo sedatha
Kwadalwa ngo Ngokwamukisa
umenzi wamathangi amanzi esikhungo sedatha
Ukukhetha umkhiqizi wethangi lamanzi lesikhungo sedatha kuncike ekhonweni eliqinisekisiwe, amaphrojekthi angempela abekiwe kanye nokusekelwa kobunjiniyela - hhayi intengo ephansi. Dinga i-ISO 9001/45001, i-NSF/ANSI 61, i-EN 1090/CE, i-WRAS/FM, qinisekisa izinkomba zamaphrojekthi ngezwe/umthamo/unyaka, futhi uqinisekise ukuthi ubuchwepheshe bethangi buhambisana nomsebenzi ngamunye.
Abasebenzi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikela umlilo kanye namanzi enqubo bahlala bebuza umbuzo owodwa osebenzayo: yiliphi ithangi lokugcina elidingwa yilo msebenzi, futhi licaciswa kanjani? Le ndatshana igxile "kumkhiqizi wethangi lamanzi lesikhungo sedatha", ihlanganisa ukukhethwa komkhiqizi wethangi lamanzi lesikhungo sedatha. 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
Okufanele Kuhlolwe Kumkhiqizi Wethangi
· Izitifiketi kuqala. Dinga i-ISO 9001 / ISO 45001 ikhwalithi nokuphepha, i-NSF/ANSI 61 (okuphuzwayo), i-EN 1090/CE (isakhiwo), i-WRAS / FM ngokusho komsebenzi.
· Ubuchwepheshe bamathangi obufakazelwe. I-GFS (AWWA D103-09, ISO 28765), i-fusion-bonded epoxy, insimbi engagqwali, i-galvanized kanye nensimbi ehlanganisiwe ngayinye ifanele imisebenzi ehlukene ye-DC; umenzi kufanele afakazele ukufana.
· Umlando wokulethwa. Cela amaphrojekthi okubhekiselwa kuwo ngezwe, umthamo nonyaka wokuqedwa - futhi uqinisekise ukuthi angempela, hhayi izimangalo ezijwayelekile.
Ukuthenga Eshayina: Ukushintshana
· Izindleko nomthamo. Abenzi bamathangi abahlanganisiwe baseShayina banikeza izindleko ezincintisanayo nendawo enkulu yokukhiqiza; isikhathi sokuhola kanye nokuhamba kufanele kuhlelwe kushejuli ye-DC.
· I-QA kanye nemibhalo. Phikelela kumasertifikathi e-mill, ukuqinisekiswa kwe-coating, amarekhodi okuhlolwa kwe-hydrostatic kanye nohlelo olucacile lwe-QA - hhayi nje intengo ephansi.
· Ezokuthutha. Amaphaneli e-modular aboshiwe athunyelwa ngamakhonteyina futhi amiswe endaweni; qinisekisa isisekelo, i-crane kanye nobubanzi bokugadwa kokumiswa.
Kungani Amandla, Hhayi Intengo Kuphela, Ewina
· Ukusekelwa kobunjiniyela. Umhlinzeki omuhle unikeza ukulinganisa, imithwalo yesisekelo, uhlelo lwe-nozzle kanye nokuzamazama komhlaba lapho kufanele khona - okungaphezu kakhulu kwegobolondo nje.
· Ububanzi bomthombo owodwa. Umenzi ohlanganisa imikhumbi ye-GFS, i-epoxy, insimbi engagqwali, i-welded kanye ne-ASME yehlisa ingozi yokuxhumana kuzo zonke izindima zomlilo, zokulungisa kanye nokupholisa.
· Insizakalo yomhlaba wonke. Ukulethwa emazweni angaphezu kwe-100 kusho ukufinyelela kwezingxenye zokushintsha kanye nokusekelwa kobuchwepheshe okubalulekile empilweni ye-DC yeminyaka eyi-10-15.
Izimo Zokusetshenziswa
· Umsebenzi wasendaweni. Fanisa ithangi nendawo yangempela, ingcindezi kanye nesidingo sokuqina.
· Ukuhlanganiswa. Phakela i-BMS/EPMS noma iphaneli yomlilo njengoba kudingeka.
· Umjikelezo wempilo. Hlela i-QA, ukuhlolwa kanye nezingxenye zokushintsha phakathi nempilo ye-DC.
Ukukhetha Nokuqhathanisa
Khetha ngekhwalithi yamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS eboshiwe kanye nensimbi ehlanganiswe nge-epoxy ziqondisa ngokushesha ezindaweni eziqinile ze-DC futhi zihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi ewelded noma ukhonkolo zifanele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umkhathi. 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 ama-Glass-Fused-to-Steel (GFS), i-fusion-bonded epoxy, insimbi engagqwali, insimbi egayiwe kanye namathangi ashiselwe kanye namaphahla e-aluminium geodesic dome kanye ne-ASME pressure vessels. Imikhiqizo yalo yamathangi iqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi isetshenzisiwe emisebenzini emazweni angaphezu kwe-100. Ohlwini lwabaqondisi abathengi lwezihloko ezingama-75, iphuzu elisebenzayo ukuthi uqinisekise izitifiketi, amaphrojekthi okubhekiselwa kuwo kanye nokusekelwa kobunjiniyela ngaphambi kokunikezwa - amandla, hhayi intengo kuphela, avikela impilo ye-DC yeminyaka eyi-10-15.
Imibuzo Evame Ukubuzwa
Umbuzo: Ngikhetha kanjani umkhiqizi wethangi lamanzi lesikhungo sedatha?
Impendulo: Dinga i-ISO 9001/45001, NSF/ANSI 61, EN 1090/CE, WRAS/FM; qinisekisa amaphrojekthi okubhekiselwa kuwo ngezwe, umthamo kanye nonyaka; futhi qinisekisa ukuthi umkhiqizi uthethelela ubuchwepheshe bethangi ngokomsebenzi ngosekelo lobunjiniyela.
Umbuzo: Yimaphi izitifiketi ezifakazela ukuthi umenzi wamathangi uthembekile?
Impendulo: I-ISO 9001 ne-ISO 45001 yekhwalithi/ukuphepha, i-NSF/ANSI 61 ne-WRAS yokuxhumana namanzi aphuzwayo, i-EN 1090/CE yensimbi yesakhiwo, kanye ne-FM lapho iphrofayili yengozi ikudinga khona.
Umbuzo: Ingabe ukuthenga amathangi evela e-China kuwumbono omuhle?
A: Kungabiza ngendlela efanele ngomthamo omkhulu wokukhiqiza, kodwa hlela isikhathi sokuhola nokuhamba, futhi uphikelele kumasertifikethi e-mill, ukuqinisekiswa kwe-coating kanye namarekhodi okuhlolwa kwe-hydrostatic - hhayi nje intengo ephansi.
Q: Yibuphi ubuchwepheshe bamathangi okufanele bunikezwe umhlinzeki we-DC?
A: I-GFS (AWWA D103-09, ISO 28765), i-epoxy ehlanganiswe ngokushisa, insimbi engagqwali, i-galvanized, insimbi ewelded kanye nemikhumbi ye-ASME - ngakho umlilo, ukugcwalisa kanye nemisebenzi ebandayo kungatholakala ngaphandle kokuqhekeza uchungechunge lokuhlinzeka.
Q: Kungani kuqinisekiswa izinkomba zephrojekthi?
A: Amaphrojekthi angempela ngezwe, umthamo kanye nonyaka wokuqedwa kufakazela amandla okuletha; izimangalo ezijwayelekile azenzi lokho. Zicela bese uhlola ukuthi ziyahambisana nomsebenzi wakho.
Q: Yiluphi usizo lobunjiniyela okufanele luhambisane nethangi?
A: Ukulinganisa, imithwalo yesisekelo, uhlelo lwama-nozzle kanye nokuzamazama komhlaba lapho kufanele - okungaphezu kakhulu kwegobolondo nje. Lokho kusekela kuvikela uhlelo lwe-DC kanye nokuphila kwalo.
Kumkhiqizi wethangi lamanzi lesikhungo sedatha, indlela esebenzayo ukuqala 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 kanye nempahla. Ukugcinwa kwamanzi esikhungo sedatha yisinqumo sezinhlelo, hhayi ukuthenga impahla; ukucacisa kahle ekuqaleni kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xoxa ngomkhakha wakho wokugcinwa kwamanzi esikhungo sedatha - imisebenzi yomlilo, yokugcwalisa kanye neyokupholisa - nonjiniyela ongaqinisekisa izitifiketi, izinkomba kanye nobuchwepheshe bethangi kuhlelo ngalunye.
