Ithangi lokugcina amanzi apholile esikhungo sedatha
Ithangi lebhafa lamanzi apholile lihlukanisa isihlungi emithwalweni yomthwalo, linciphisa ukuqala kwekhompressa futhi lihlinzeke izinguquko zesikhashana; lilinganise ukuba libe amaminithi angu-3-15 okusebenza kwesihlungi ku-delta-T yokuklama. Sebenzisa ithangi le-atmospheric elineyunithi yokucindezela noma isitsha se-ASME esicindezelwe kuye ngokucindezela komjikelezo, nokufakwa kwe-insulation ne-glycol lapho kudingeka.
Abasebenzi bezikhungo zedatha abahlela amasistimu okupholisa, okuvimbela umlilo kanye namanzi ezinqubo bayahlala bebuza umbuzo oyedwa ongokoqobo: yiluphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile "ethangini lokugcina lamanzi abandayo esikhungo sedatha", ihlanganisa ithangi lokugcina lamanzi abandayo esikhungo sedatha. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olufanele, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Ithangi Lokugcina Lamanzi Abandayo Lenzani
· Ihlukanisa isihlungi sokubandisa emthwalweni. Ithangi lokugcina limunca ukushintshashintsha komthwalo ukuze isihlungi sisebenze isikhathi eside, siqale izikhathi ezimbalwa - kuvikela ama-compressor futhi kuthuthukisa ukusebenza kahle komthwalo oyingxenye.
· 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 kwethangi lokugcina, hhayi ngesidingo esiguquguqukayo sanjalo.
Ukulinganisa nokufaka umfutho
· Umthetho wesikhathi sokusebenza. Umthamo we-buffer uvame ukuhlosela amaminithi angu-3-15 okusebenza kwe-chiller ku-design delta-T (rho x cp x delta-T); okwengeziwe emithwalweni eguquguqukayo.
· Okucindezelwe kuqhathaniswa nokujwayelekile. Amalophu abandayo avaliwe angase asebenzise i-buffer ecindezelwe (ASME) noma ithangi elijwayelekile elineyunithi ehlukile yokucindezela; ukukhetha kuncike kwingcindezi yelophu.
· I-Glycol nokuvikelwa ekubandeni. Ezimweni ezibandayo noma zomthwalo ongaphelele ingxube ye-glycol ivimbela ukubanda; izinto zethangi neze-trim kufanele zihambisane noketshezi.
Izinto Nemigomo
· Okuqoshiwe noma i-stainless. I-Epoxy-coated noma i-GFS bolted steel, i-stainless, noma i-welded steel zihambisana nomsebenzi opholile; i-NSF/ANSI 61 ibalulekile kuphela uma iseduze namanzi okuphuza.
· I-ASME lapho kucindezelwe. Imikhumbi ye-chilled-water noma ye-TES ecindezelwe ingaphansi kwe-ASME BPVC Section VIII; ingcindezi yokuklama nezinga lokushisa kucacisiwe, akucatshangelwanga.
· Ukufakwa kwe-insulation. Amathangi apholile adinga i-insulation ne-vapor barrier ukunciphisa ukungena nokujiya emhlabathini we-energy-plant.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. I-NFPA 22 indawo yokugcina igcinwa ihlukile emanzini okusebenza.
· Ukugcwalisa okupholile. Ukushintshwa okungapheli kokulahlekelwa kombhoshongo/okufaka umswakama.
· Ibhafa epholile / i-TES. Ukuhlukanisa nokugcina ukushisa kwesikhathi esingekho emsebenzini.
· Inqubo kanye namanzi okuphuza. Ukudla kwesithimela, ukufaka umswakama, ukuhlanza 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 eziqinile ze-DC futhi zihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi ehlanganisiwe noma ukhonkolo zifanele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umkhathi. Qinisekisa izitifiketi namaphrojekthi okubhekiselwe kuwo ngaphambi kokunikeza umsebenzi.

Ubungcweti Benkampani
I-Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.) ihlinzeka ngamathangi amakhulu okugcina amanzi aboshiwe nalwelded kanye nemikhumbi yengcindezi ye-ASME, eqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, nokulethwa emazweni angaphezu kwe-100. Ukuhlanganiswa kokugcina ukushisa nesitshalo samanzi abandayo sesikhungo sedatha kuyindawo yokuxhumanisa yobunjiniyela okufanele iqinisekiswe ngokuhambisana nomklamo wokupholisa; le ndatshana iwumhlahlandlela wobuchwepheshe, hhayi inkomba yephrojekthi.
Imibuzo Evame Ukubuzwa
Umbuzo: Yini eyenziwa ithangi le-buffer yamanzi apholile?
Impendulo: Ihlukanisa isihlungi emagxegxeni omthwalo ukuze i-compressor isebenze isikhathi eside ngokuqalisa okumbalwa, futhi ihlanganisa izikhathi zoshintsho ngesikhathi sokukhuphuka noma ukudluliswa kwamaphampu ngaphandle kokuphazamisa ukuvikelwa kokuhamba okuphansi.
Umbuzo: Ngisayizi kanjani ithangi le-buffer yamanzi apholile?
A: Umthetho ojwayelekile uhlosela amaminithi angu-3-15 okusebenza kwesihlungi esimisiwe ku-delta-T yokuklama (ivolumu isuka ekuminyaneni x ubukhulu bokushisa x delta-T); okwengeziwe emithwalweni eguquguqukayo kakhulu.
Umbuzo: Ithangi le-buffer elinomfutho noma elingenawo umfutho?
Impendulo: I-loop epholile evaliwe ingasebenzisa ithangi elingenawo umfutho 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 ongaphelele ingxube ye-glycol ivimbela ukufika kweqhwa; izinto zethangi nezokuhlobisa kufanele zihambisane noketshezi, futhi kudingeka i-insulation ene-vapor barrier.
Umbuzo: Iyiphi into esetshenziswayo kumathangi e-buffer apholile?
Impendulo: Insimbi eboliwe nge-epoxy noma i-GFS ehlanganisiwe, insimbi engagqwali noma insimbi eshiselwe; i-NSF/ANSI 61 kuphela uma iseduze namanzi okuphuza.
Umbuzo: Yimiphi imigomo esebenzayo?
Impendulo: I-AWWA D103-09 (eboshiwe) noma i-D100 (ehlanganisiwe); i-ASME BPVC VIII uma inengcindezi; i-NSF/ANSI 61, i-EN 1090/CE, i-ISO 9001/45001 ngokwesidingo somsebenzi.
Nge-"ithangi lokugcina amanzi abandayo esikhungo sedatha", 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 impahla; ukukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesikhungo sakho sokupholisa sedatha, ukugcwalisa noma ukucaciswa kwethangi lokugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
