Yiziphi Alloy Plates? .
(Ukusetshenziswa kwama-alloy Plates Ekukhiqizeni Izishintshi Zokushisa Zezimboni)
Amapuleti engxubevange ayizingcezu zensimbi ezisezingeni elenziwe ngokuxuba izici ezimbili noma ngaphezulu, okungenani eyodwa iyinsimbi. Le miksi ihlinzeka ngepuleti lasekhaya izimfanelo eziphezulu eziyingqayizivele izinsimbi ezihlanzekile ngokuvamile ezingenazo. Izingxenye ezivamile ze-alloying zihlanganisa i-chromium, i-nickel, i-molybdenum, kanye ne-vanadium. Lezi zengezo zingenza insimbi ibe namandla, avikeleke kakhulu ekushiseni, noma ukwazi kangcono ukusingatha ukuwohloka. Ekusethweni kwezimboni, amapuleti alloy akuzona nje izinsiza– ziyizixazululo ezakhiwe. Ngokwesibonelo, okuhlanganisa izingxenye ze-micro-alloying ezifana ne-niobium ne-vanadium zingathuthukisa kakhulu amandla nokushisela. Ungathola kabanzi mayelana nokuthi lezi zithako ezincane zenza kanjani umehluko omkhulu ekusebenzeni kwensimbi lo mhlahlandlela ophelele. Ngokungafani ne-carbon steel ejwayelekile, amapuleti e-alloy akhelwe ukudinga izindawo lapho ukwehluleka kungeyona enye indlela.
Kungani Usebenzisa Izingcwecwe Zengxubevange Kuma-Warmth Exchangers? .
Ama-exchanger afudumele asusa ukushisa asuke kolunye uketshezi aye kolwengeziwe ngaphandle kokuwavumela ukuba ahlangane. Basebenza ngaphansi kwengcindezi ephezulu, amazinga okushisa aphezulu, kanye nezimo ezivamise ukucekela phansi. Insimbi evamile ingase isonte, ukuphuka, noma ukugqwala ezimweni ezinjalo. Amapuleti e-alloy axazulula lezi zinkinga. Izinsiza zabo ezithuthukisiwe ze-thermal conductivity zifudumeza kakhulu ngempumelelo. Ukumelana kwazo ne-oxidation kubonisa ukuthi zihlala isikhathi eside ngisho nalapho zingaphansi kwamagesi afudumele noma umhwamuko. Ngaphezu kwalokho, ama-alloys amaningana agcina amandla awo ekushiseni– into elula ye-carbon steel ingakwazi ukugwema ngokuthembekile. Izimboni zikhetha amapuleti e-alloy njengoba amanani entengo ephansi eyimali, kanye nezindaba zokuphepha. Ukusebenzisa umkhiqizo ofanele kusukela ekuqaleni kuhlala kucacile ekuvuzeni, izinyembezi, kanye nezinsiza zokulungisa ezibizayo ezansi komugqa. Yingakho abaklami bechaza amapuleti e-alloy lapho beklama abashintshi bokufudumala bezitshalo zamandla, izikhungo zokukhiqiza amakhemikhali, noma izindawo zokuhluza uwoyela.
Kahle Kanjani Amapuleti e-alloy asetshenziswa ekukhiqizeni ama-Warmth Exchangers? .
Ukwenza i-exchanger yokufudumala kusuka kumapuleti e-alloy kuhlanganisa nenani lezinyathelo ezinembile. Ekuqaleni, i-alloy grade efanele ikhethwa ngokusekelwe esimweni sokusebenza– izinga lokushisa, ukucindezeleka, kanye nohlobo lwe-fluid yonke inkinga. Khona-ke, amapuleti amakhulu engxubevange asikwa abe yizindawo ezincane kusetshenziswa i-plasma noma i-laser cutting. Lezi zinto zakhiwa ngokugingqika noma ngokusunduza ukuze kuthuthukiswe amashubhu, izembozo, noma ezikhungathekisayo. Izimpawu zokushisela zihambisana nezingxenye, futhi ngaphansi, ukushisela kwe-alloy kubalulekile. Amanye ama-alloy adinga ukushisa kwangaphambili noma ukwelashwa kokushisa kwangemuva kwe-weld ukugwema ukuhlukana. Ngemva kokusetha, uhlelo ludlula ekuhloleni ukuvuza nokuqina. Ukudlulisa lezi ezinzima, izingxenye ezinkulu ngaphezu kwalokho zidinga ukwelashwa. Ukulungiswa kwezinto ezikhethekile kuqinisekisa ukuthi amapuleti asekhaya afika engonakalisiwe futhi eselungele ukukhiqizwa. Uma uphatha izimpahla ezinkulu, bheka izindlela ezingcono kakhulu zokuthutha amapuleti amakhulu engxubevange ngokuphepha lomthombo. Zonke izenzo– kusukela ekukhethweni komkhiqizo kuya ekuhlolweni kokugcina– kufanele ihlangabezane nemibandela yemakethe eqinile.
Izicelo ze-Alloy Plate-Based Warm Exchangers .
Amapuleti e-alloy exchanger afudumele akunoma yikuphi emakethe esindayo. Ekukhiqizeni amandla, bapholisa ama-lubes e-wind turbine noma babuyise imfucuza efudumele evela kumagesi akhipha umoya. Ezitshalweni ze-petrochemical, baphatha ama-asidi anokhahlo kanye nama-hydrocarbon anengcindezi ephezulu. Amapulatifomu kawoyela angasogwini awasebenzisa ezinhlelweni zokupholisa amanzi olwandle, lapho amanzi anosawoti ngokuqinisekile ayengangena khona ensimbi evamile ngemva kwezinyanga. Nasekuphatheni ukudla, amapuleti athile e-alloy ekhwalithi ephezulu aqinisekisa inhlanzeko nokuqina ngesikhathi se-pasteurization. Ukusetshenziswa okwengeziwe okungalindelekile? Izinsiza zenuzi, lapho ukwethembeka kungaxoxiswana khona. Ucwaningo olufanayo lwesayensi olwenza amapuleti e-alloy alungele ukushintshisana okufudumele futhi awenza alungele ezinye izinhlelo zokusebenza ezisezingeni eliphezulu.– njengokwakha izisefo ezivikeleke kakhulu neziphephile ezimelana nokubhobolwa neziteleka zamalambu. Nginentshisekelo yokuthi insimbi efanayo ncamashi isebenza kanjani imisebenzi ehlukene? Bona ukuthi amapuleti e-alloy athuthukisa kanjani izixazululo ezihlala isikhathi eside zokuphepha nokuvikeleka kokuthi leli khasi lewebhu. Noma ngabe amandla, amakhemikhali, noma isivikelo, amapuleti e-alloy ahlinzeka ngokusebenza ongathembela kukho.
Imibuzo Evame Ukubuzwa Mayelana Nezingcwecwe Zengxubevange Ezishintshisani Zokushisa .
1. Ingabe zonke izingqimba ze-alloy zifanelekile ukushintshanisa ukufudumala?
Cha. Amamaki akhethekile kuphela athuthukisiwe okukhathazeka okuphezulu kokushisa kanye nokumelana nokonakala okufanele kusetshenziswe. Izinketho ezijwayelekile zihlanganisa insimbi engagqwali engu-316L, Ikhoneli, kanye nama-alloys e-duplex.
2. Ingabe amapuleti e-alloy akubuyisela emuva ngaphezu kwensimbi evamile?
Yebo, ngokuvamile bakubuyisela emuva okuningi ngaphambili. Nokho impilo yabo ende yesevisi, ukunciphisa ukulungiswa, nokusebenza okungcono kakhulu ngokuvamile konga imali ngesikhathi.
3. Ingabe amapuleti engxubevange angagaywa kabusha?
Nakanjani. Iningi lezinsimbi ze-alloy zigaywa kabusha ngokuphelele ngaphandle kokulahlekelwa izindawo zokuhlala ezibalulekile noma ezohwebo. Lokhu kubenza babe ne-eco-friendly ngokuzayo.
4. Ukuthi amapuleti e-alloy kufanele abe mkhulu kangakanani okushintshanisa ukufudumala?
Ukuminyana kuncike ekucindezelekeni nasezidingweni zokushisa. Amalungu afanayo ajwayelekile asuka 3 mm ukuya phezulu 50 mm. Abaqambi bahlanganisa ukucaciswa okunembile besebenzisa amakhodi esitayela afana ne-ASME.
5. Kwenzekani uma ingxubevange engalungile ikhethiwe?
Kungabangela ukugqwala okusheshayo, ukukala, noma ukwehluleka komshini. Njalo funa iseluleko kumashadi ahambisana nomkhiqizo ngaphambi kokulungisa isitayela.
6. Ingabe kukhona ukukhetha amapuleti alloy?
(Ukusetshenziswa kwama-alloy Plates Ekukhiqizeni Izishintshi Zokushisa Zezimboni)
Kwezinye izimo. I-Titanium noma i-graphite ingasetshenziswa ezimweni ze-niche, kodwa amapuleti e-alloy ahlinzeka ngebhalansi engcono kakhulu yentengo, ubulukhuni, kanye nokuvumelana nezimo kwabaningi abashintshisana ngokufudumala kwezimboni.
