ukwandiswa kwebhafa yesikhungo sedatha kanye nemikhumbi ye-TES
Kwadalwa ngo Ngokwamukisa
ukwandiswa kwebhafa yedatha ephakathi kanye nemikhumbi ye-TES
Ithangi lebhafa lamanzi apholile lihlukanisa isihlungi emithwalweni yomthwalo, linciphisa ukuqala kwekhompressor futhi lihlanganise izikhathi zokushintsha; lilinganise ukuba libe ngamaminithi angu-3-15 okusebenza kwesihlungi ngedizayini ye-delta-T. Sebenzisa ithangi le-atmospheric elineyunithi yokucindezela noma umkhumbi ocindezelwe we-ASME 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 elidingekayo kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile ku-"ukwandiswa kwe-buffer yezikhungo zedatha kanye nemikhumbi ye-TES", okuhlanganisa ukwandiswa kwe-buffer nemikhumbi ye-TES e-DC. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olufanele, into kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Ithangi le-Buffer Yamanzi Apholile Lenzani
· Ihlukanisa isihlungi emthwalweni. Ithangi le-buffer limunca ukushintshashintsha komthwalo ukuze isihlungi sisebenze isikhathi eside, siqale izikhathi ezimbalwa - sivikela ama-compressor futhi sithuthukisa 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 namaphampu ahamba ngezinga lokushisa le-buffer, hhayi ngesidingo esisheshayo esingaqondile.
Ukulinganisa nokufaka umfutho
· Umthetho wesikhathi sokusebenza. Umthamo we-buffer ngokuvamile uhlosela 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 elinophiko oluhlukile lokucindezela; ukukhetha kuncike kwingcindezi yelophu.
· Ukuvikelwa kwe-glycol nokugwema ukufa. Ezimweni ezibandayo noma zomthwalo ongaphelele ingxube ye-glycol ivimbela ukufa; izinto zethangi neze-trim kufanele zihambisane noketshezi.
Izinto Zokwakha Namazinga
· Okunamekwe noma i-stainless. Insimbi ebolile ene-epoxy noma i-GFS ehlanganisiwe, i-stainless, noma insimbi ebolile 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 Section VIII; ingcindezi yokuklama nezinga lokushisa kucacisiwe, akucatshangwa.
· Ukufakwa kwe-insulation. Amathangi apholile adinga i-insulation nesivikelo somhwamuko ukunciphisa ukwanda nokujiya emhlabathini wemboni yamandla.
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 okungekho ngesikhathi sokuphumula.
· Inqubo namanzi okuphuza. Ukudla kwesigayo, ukufaka umswakama, ukuhlanza lapho izinga lihambisana khona.
Ukukhetha nokuqhathanisa
Khetha ngokwekhwalithi yamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS ehlanganiswe ngamabhawudi nensimbi ehlanganiswe nge-epoxy zisungulwa ngokushesha ezindaweni eziqinile ze-DC futhi zihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi ewelidiwe noma ukhonkolo zifanele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela uma ingcindezi idlula umkhathi. Qinisekisa izitifiketi namaphrojekthi okubhekiselwa 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, nokulethwa emazweni angaphezu kwe-100. Ukuhlanganiswa kokugcina ukushisa nendawo yokugcina amanzi ebandayo yesikhungo sedatha kuyindawo yokuxhumanisa yobunjiniyela okufanele iqinisekiswe ngokuhambisana nomklamo wokupholisa; le ndatshana iwumhlahlandlela wezobuchwepheshe, hhayi inkomba yephrojekthi.
Imibuzo Evame Ukubuzwa
U: Yini eyenziwa ithangi le-buffer yamanzi apholile?
I: Ihlukanisa isihlanzi emishintsheni yomthwalo ukuze i-compressor isebenze isikhathi eside ngokuqalisa okumbalwa, futhi ihlanganisa izikhathi zoshintsho 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 isuka ekuminyaneni x ukushisa okukhethekile x i-delta-T); okwengeziwe emithwalweni eguquguqukayo kakhulu.
Umbuzo: Ithangi le-buffer elinomfutho noma elingenawo umfutho?
Impendulo: Umjikelezo opholile ovaliwe ungase usebenzise ithangi elingenawo umfutho elinesigaba esihlukile sokufaka umfutho, noma isitsha se-ASME esinomfutho. Ukukhetha kuncike kumfutho womjikelezo nokuklama.
Umbuzo: Ingabe amathangi e-buffer apholile adinga i-glycol?
Impendulo: Ezimweni ezibandayo noma zomthwalo ongaphelele ingxube ye-glycol ivimbela ukufriza; izinto zethangi nezokuhlobisa kufanele zilungele uketshezi, futhi kudingeka i-insulation enesivikelo somhwamuko.
Umbuzo: Iyiphi into esetshenziswayo kumathangi e-buffer apholile?
A: Insimbi ehlanganiswe nge-epoxy noma insimbi ehlanganiswe ngamabhawudi ye-GFS, insimbi engagqwali noma ewelidiwe; i-NSF/ANSI 61 kuphela uma iseduze namanzi okuphuza.
U: Yimiphi imigomo esebenzayo?
A: I-AWWA D103-09 (ehlanganiswe ngamabhawudi) noma i-D100 (ewelidiwe); i-ASME BPVC VIII uma inengcindezi; i-NSF/ANSI 61, i-EN 1090/CE, i-ISO 9001/45001 njengoba umsebenzi udinga.
Okokwandisa ibhafa yesikhungo sedatha kanye nemikhumbi ye-TES, indlela esebenzayo ukuqala emsebenzini - izidingo zekhwalithi yamanzi, ingcindezi, umthamo kanye nokuqina - bese uvumela izinga (NFPA 22, AWWA D103-09/D100, ASME BPVC VIII, NSF/ANSI 61) linqume uhlobo lwethangi kanye nempahla. Ukugcinwa kwamanzi esikhungo 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, lokugcwalisa noma lokugcina ukushisa, umthamo kanye nokukhethwa kwempahla.
