Ithangi Lokupholisa Elibalulekile
Ithangi lebhafa lamanzi apholile lihlukanisa isihlungi emithwalweni yokuguquguquka, linciphisa ukuqala kwe-compressor futhi lihlinzeka ngezikhathi zokuguquguquka; lilinganise ukuthi lisebenze amaminithi angu-3-15 esihlungi 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.
Abaphathi bezikhungo zedatha abahlela amasistimu okupholisa, okuvikela umlilo kanye namanzi ezinqubo bayahlala bebuza umbuzo oyedwa ongokoqobo: yiluphi ithangi lokugcina elidingwa yilo msebenzi, futhi linikezwa kanjani? Le ndatshana igxile ku-"ithangi lokupholisa elibalulekile", ihlanganisa ukuthembeka kwethangi lokupholisa elibalulekile. 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
Okwenziwa Ithangi Lokugcina Lamanzi Apholile
· Ihlukanisa isihlungi sokubandisa emthwalweni. Ithangi lokugcina limunca ukushintshashintsha komthwalo ukuze isihlungi 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 kwethangi lokugcina, hhayi ngesidingo esiguquguqukayo sanjalo.
Ukulinganisa nokufaka umfutho
· Umthetho 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.
· Okucindezelwayo kuqhathaniswa nomoya ojwayelekile. Amalophu abandayo avaliwe angasebenzisa ibhafa ecindezelwayo (ASME) noma ithangi lomoya elinomoya ojwayelekile elinesigaba sokucindezela esihlukile; ukukhetha kuncike kwingcindezi yelophu.
· Ukuvikelwa kwe-glycol nokubanda. Ezimeni 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 ehlanganisiwe, i-stainless, noma insimbi eshiselwe iyafaneleka emsebenzini 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 Isigaba VIII; ingcindezi yokuklama nezinga lokushisa kucacisiwe, akucatshangwa.
· Ukufakwa kwe-insulation. Amathangi apholile adinga i-insulation nesivimbelo somhwamuko ukunciphisa ukungena nokujiya kwamanzi endaweni yamandla.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. I-NFPA 22 indawo yokugcina igcinwa ihlukile emanzini okucubungula.
· Ukugcwalisa okupholile. Ukushintshwa kokulahlekelwa okuqhubekayo kombhoshongo/okufaka umswakama.
· Ibhafa epholile / i-TES. Ukuhlukanisa nokugcina ukushisa okungekho ngesikhathi sokusebenza.
· Inqubo kanye namanzi okuphuza. Ukudla kwesithimula, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha nokuqhathanisa
Khetha ngokwezinga lamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni somaka. I-GFS eboshiwe kanye nensimbi ehlanganiswe nge-epoxy yakha ngokushesha ezindaweni eziwumngcingo ze-DC futhi ihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi eshiselwe noma ukhonkolo kufaneleka ezidingweni 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 ithumela emazweni angaphezu kwe-100. Ukuhlanganiswa kokugcina ukushisa nesitshalo samanzi abandayo sesikhungo sedatha kungumsebenzi 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 isiqandisi emithwalweni yokushintshashintsha 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 esimisiwe ku-delta-T yokuklama (ivolumu evela kubuningi x ubukhulu obuthile 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 (eshiselwe); i-ASME BPVC VIII uma inengcindezi; i-NSF/ANSI 61, i-EN 1090/CE, i-ISO 9001/45001 njengoba umsebenzi udinga.
Nge-\"mission critical cooling 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 impahla; ukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesicaciso sethangi lakho lokupholisa lesikhungo sedatha, ukugcwalisa noma ukugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
