umhlinzeki wethangi lamanzi lesikhungo sedatha
Kwadalwa ngo Ngokwamukisa
umhlinzeki wamathangi amanzi esikhungweni sedatha
Ukukhetha umkhiqizi wethangi lamanzi lesikhungo sedatha kuncike ekhonweni eliqinisekisiwe, kumaphrojekthi anereferensi yangempela 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, okuvimbela umlilo kanye namanzi enqubo bahlala bebuza umbuzo owodwa osebenzayo: yiliphi ithangi lokugcina elidingwa yilo msebenzi, futhi licaciswa kanjani? Le ndatshana igxile ku-"umhlinzeki wethangi lamanzi lesikhungo sedatha", ihlanganisa umhlinzeki wethangi lamanzi lesikhungo sedatha. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi indlela 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 eweldediwe 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: Izinto Okufanele Zicatshangelwe
· Izindleko nomthamo. Abenzi bamathangi abahlanganisiwe baseShayina banikeza izindleko ezincintisanayo nendawo enkulu yokukhiqiza; isikhathi sokulethwa kanye nokuhamba kwezimpahla 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 ngamakhontena futhi amiswe endaweni; qinisekisa isisekelo, i-crane kanye nobubanzi bokugadwa kokumiswa.
Kungani Amandla, Hhayi Nje Intengo, Ewina
· Ukusekelwa kobunjiniyela. Umhlinzeki omuhle unikeza usayizi, imithwalo yesisekelo, uhlelo lwe-nozzle kanye nokuzamazama komhlaba lapho kufanele khona - okungaphezu kakhulu kwegobolondo elingenalutho.
· Ububanzi bomthombo owodwa. Umenzi ohlanganisa izitsha ze-GFS, i-epoxy, insimbi engagqwali, ezishishelwe kanye ne-ASME unciphisa ingozi yokuxhumana phakathi kwemisebenzi yomlilo, yokulungisa nokubandayo.
· Insizakalo yomhlaba wonke. Ukulethwa emazweni angaphezu kwe-100 kusho ukufinyelela kwezingxenye zokushintsha nokusekelwa kobuchwepheshe okubalulekile empilweni ye-DC yeminyaka eyi-10-15.
Izimo Zokusetshenziswa
· Umsebenzi wasendaweni. Fanisa ithangi nendlela 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 ngokwekhwalithi yamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS eboshiwe kanye nensimbi ehlanganiswe nge-epoxy ziqhuma 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 kokunikezwa.

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 engaphezu kwezindawo eziyi-100 emazweni angaphezu kwe-100. Ohlwini lwabaqondisi abathengi olunezihloko ezingama-75, iphuzu elisebenzayo ukuthi uqinisekise izitifiketi, imisebenzi okubhekiselwe kuyo kanye nokusekelwa kwezobunjiniyela ngaphambi kokunikezwa - amandla okusebenza, 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 okubhekiselwe kuwo ngokwezwe, umthamo kanye nonyaka; futhi qinisekisa ukuthi umkhiqizi uthethelela ubuchwepheshe bethangi ngokomsebenzi ngosekelo lobunjiniyela.
Umbuzo: Yimaphi amasertifikethi afakazela ukuthi umenzi wethangi 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.
Umbuzo: Ingabe ukuthenga amathangi evela e-China kuwumbono omuhle?
A: Kungaba yindleko ephumelelayo ngomthamo omkhulu wokukhiqiza, kodwa hlela isikhathi sokulethwa nokuhamba kwezimpahla, 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 ngokwezwe, umthamo kanye nonyaka wokuqedwa kufakazela ikhono lokuletha; izimangalo ezijwayelekile azenzi lokho. Zicela bese uhlola ukuthi ziyahambisana yini 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 nokuphila.
Kumhlinzeki 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 nento esetshenziswayo. Ukugcinwa kwamanzi esikhungo sedatha yisinqumo sezinhlelo, hhayi ukuthenga kwempahla; ukucacisa kahle ekuqaleni kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xoxa ngomsebenzi wakho wokugcina amanzi esikhungo sedatha - umlilo, ukugcwalisa kanye nemisebenzi ebandayo - nonjiniyela ongaqinisekisa izitifiketi, izinkomba kanye nobuchwepheshe bethangi kuhlelo ngalunye.
