Ithangi Lokugcina Lamanzi Apholile Elinomfutho
Ithangi lokugcina lamanzi apholile lihlukanisa isihlungi emithwalweni yomthwalo, linciphisa ukuqala kwekhompresha futhi lihlanganise izikhathi zokushintsha; lilinganise ukuba libe ngamaminithi angu-3-15 okusebenza kwesihlungi ngedizayini ye-delta-T. Sebenzisa ithangi le-atmospheric elineyunithi yokufaka umfutho noma isitsha se-ASME esinomfutho kuye ngokucindezela komjikelezo, nokufakwa kwe-insulation ne-glycol lapho kudingeka.
Abaphathi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikela umlilo kanye namanzi enqubo baqhubeka nokubuza umbuzo oyingqayizivele: yiluphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile "kuthangi lokugcina lamanzi ahlanjululwe anengcindezi", ihlanganisa ithangi lokugcina lamanzi ahlanjululwe anengcindezi. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe emazingeni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olulungile, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Ithangi Lokugcina Lamanzi Ahlanjululwe Elenzayo
· Ihlukanisa isipholisi emthwalweni. Ithangi lokugcina limunca ukushintshashintsha komthwalo ukuze isipholisi sisebenze isikhathi eside, siqale izikhathi ezimbalwa - kuvikela ama-compressor futhi kuthuthukisa ukusebenza kahle kwengxenye yomthwalo.
· Ihlanganisa isidingo sesikhashana. Ngesikhathi sokukhuphuka noma ukudluliswa kwepompo, ithangi linikeza noma limunca umthamo ngaphandle kokuphazamisa ukuvikelwa kokugeleza okuphansi.
· Ivumela ukulandelana. Ama-chiller amaningi namapompo ahlelwa ngezinga lokushisa lethangi, hhayi ngesidingo esiguquguqukayo sanjalo.
Ukulinganisa nokufaka umfutho
· Umthetho wokulinganisa wesikhathi sokusebenza. Umthamo we-buffer uvame ukuhlosela imizuzu engu-3-15 yokusebenza kwe-chiller ku-design delta-T (rho x cp x delta-T); okwengeziwe emithwalweni eguquguqukayo.
· Ukucindezelwa kuqhathaniswa nomoya ojwayelekile. Amalophu abandayo avaliwe angasebenzisa i-buffer ecindezelwe (ASME) noma ithangi lomoya elinomshini wokucindezela ohlukile; ukukhetha kuncike kwingcindezi yelophu.
· Ukuvikelwa kwe-glycol nokubanda. Ezimweni ezibandayo noma zomthwalo ongaphelele ingxube ye-glycol ivimbela ukubanda; izinto zethangi neze-trim kufanele zihambisane noketshezi.
Izinto Nemigomo
· Okunamekwe noma i-stainless. Insimbi ebolile nge-epoxy noma i-GFS ehlanganiswe ngamabhawudi, i-stainless, noma insimbi ebilisiwe kufanele ihambisane nomsebenzi opholile; i-NSF/ANSI 61 ibalulekile kuphela uma iseduze namanzi okuphuza.
· I-ASME lapho kunengcindezi. Imikhumbi ye-chilled-water noma ye-TES enengcindezi ingaphansi kwe-ASME BPVC Section VIII; ingcindezi yokuklama nezinga lokushisa kucacisiwe, akucatshangwa.
· Ukufakwa kwe-insulation. Amathangi apholile adinga i-insulation kanye ne-vapor barrier ukunciphisa ukwanda nokujiya emhlabathini we-energy-plant.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. I-NFPA 22 indawo yokugcina igcinwe ihlukile emanzini okusebenza.
· Ukugcwalisa okupholile. Ukushintshwa okungapheli kokulahlekelwa kombhoshongo/okufakwa komswakama.
· Isigcino esipholile / i-TES. Ukuhlukanisa nokugcina ukushisa okungekho ngesikhathi sokuphumula.
· Inqubo kanye namanzi okuphuza. Ukudla kwesithimela, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha nokuqhathanisa
Khetha ngokwezinga lamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS eboshiwe kanye nensimbi ehlanganiswe nge-epoxy zisungulwa ngokushesha ezindaweni eziwumfantu ze-DC futhi zihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi eshiselwe noma ukhonkolo zifanele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umkhathi. Qinisekisa izitifiketi namaphrojekthi okubhekiselwe kuwo ngaphambi kokunikeza.

Ubungcweti benkampani
I-Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.) ihlinzeka ngamathangi amakhulu okugcina amanzi aboshiwe futhi ashiselwe kanye nemikhumbi yengcindezi ye-ASME, eqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, futhi ithunyelwa emazweni angaphezu kwe-100. Ukuhlanganiswa kokugcina ukushisa nendawo yamanzi abandayo yesikhungo sedatha kuwumsebenzi wokuxhumanisa ubunjiniyela okufanele kuqinisekiswe ngokuhambisana nomklamo wokupholisa; le ndatshana iwumhlahlandlela wezobuchwepheshe, hhayi inkomba yephrojekthi.
Imibuzo Evame Ukubuzwa
U: Yini eyenziwa ithangi le-buffer yamanzi apholile?
I: Ihlukanisa isihlanzi emishini yokushintsha komthwalo ukuze i-compressor isebenze isikhathi eside ngokuqalisa okumbalwa, futhi ihlanganisa izikhathi zokushintsha ngesikhathi sokukhuphuka noma ukudluliswa kwamaphampu ngaphandle kokuphazamisa ukuvikelwa kokugeleza okuphansi.
U: Ngingayilinganisa kanjani ithangi le-buffer yamanzi apholile?
A: Umthetho ojwayelekile uhlosela amaminithi angu-3-15 okusebenza kwesihlungi esisebenza ngedizayini ye-delta-T (ivolumu evela kubuningi x ukushisa okukhethekile x i-delta-T); okwengeziwe emithwalweni eguquguqukayo kakhulu.
Umbuzo: Ithangi le-buffer elinomfutho noma elinomoya?
Impendulo: I-loop epholile evaliwe ingasebenzisa ithangi elinomoya elinesigaba sokufaka umfutho esihlukile, noma isitsha se-ASME esinomfutho. Ukukhetha kuncike kumfutho we-loop kanye nomklamo.
Umbuzo: Ingabe amathangi e-buffer apholile adinga i-glycol?
Impendulo: Ezimweni ezibandayo noma zomthwalo oyingxenye ingxube ye-glycol ivimbela ukufika kweqhwa; izinto zethangi nezokulungisa kufanele zilungele uketshezi, futhi kudingeka i-insulation enesivikelo somhwamuko.
Umbuzo: Iyiphi into esetshenziswayo kumathangi e-buffer apholile?
Impendulo: Insimbi eboliwe nge-epoxy noma i-GFS ehlanganisiwe, insimbi engagqwali noma insimbi ehlanganisiwe; i-NSF/ANSI 61 kuphela uma iseduze namanzi okuphuza.
Umbuzo: Yimiphi imigomo esebenzayo?
Impendulo: I-AWWA D103-09 (eboshiwe) noma i-D100 (eshiselwe); i-ASME BPVC VIII uma inengcindezi; i-NSF/ANSI 61, i-EN 1090/CE, i-ISO 9001/45001 ngokwesidingo somsebenzi.
Nge-\"pressurised chilled water storage tank\", indlela esebenzayo iwukuqala 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 esikhungweni sedatha kuyisinqumo sezinhlelo, hhayi ukuthenga okujwayelekile; ukukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesicaciso sakho sethangi lokupholisa lesikhungo sedatha, lokugcwalisa noma lokugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
