Ukungena komoya emhubheni kuyahluleka—hhayi ngenxa yokuntula umoya, kodwa ngenxa yokubola okubangelwa ukugqwala. Sizibonele mathupha: abalandeli abafakwe emigodini yezitshalo zamakhemikhali balahlekelwa ubuqotho be-blade phakathi nezinyanga ezingu-18; imigudu yasogwini yezinga lasolwandle ibika ukuthi igoba izindlu ngemva nje komjikelezo owodwa wasebusika; ngisho nemigudu kamasipala enokhonkolo ithuthukisa ukuqhekeka kwengcindezi eqhutshwa yi-chloride ezungeze ama-flange akhuphukayo. Ukugqwala akuzimemezeli ngama-alamu—kuhleba ngokulahleka kancane kancane, ukudlidliza okukhuphukayo, nohambo lwezimoto olungachazeki. Kungakho a ifeni yomhubhe ekwazi ukumelana nokugqwala akuyona intuthuko. Kuyisidingo esiyisisekelo sokungenisa umoya esihlala njalo.
Kungani Abalandeli Abajwayelekile Behluleka Ngaphansi Komshoshaphansi—nokuthi Yini Ebambekayo
Iningi labalandeli bomhubhe bathatha umoya we-ambient. Imigudu yangempela iletha umhwamuko we-asidi, inkungu egcwele usawoti, i-sulphur dioxide ephuma ku-diesel exhaust, noma ukuhlanganisa i-condensate ezindaweni eziphansi. Izindlu zensimbi zekhabhoni zigqwala ku-0.1–0.3 mm/ngonyaka ezindaweni ezinjalo—okwanele ukulimaza ukuqina kwesakhiwo ngaphansi kweminyaka emihlanu. I-Aluminium imelana nosawoti kodwa incibilika emafutheni aneasidi. I-Stainless 304 ibamba ukuchayeka okuncane kodwa ihlushwa ukuhlaselwa kwe-intergranular eduze kokushisela lapho ama-chloride egxilile. Ukulungiswa akuyona insimbi ewugqinsi. Ukumataniswa kwezinto ezihlakaniphile kanye nokuvikelwa kwezinga lenqubo.
I-Zibo Hongcheng Fan Co., Ltd. injiniyela leli qiniso kuwo wonke amayunithi. Abalandeli babo bomhubhe abangagqwali basebenzisa ukuzivikela okukabili: izakhiwo eziyisisekelo ze-ASTM A588 weathering steel (ene-copper-chromium-nickel alloying) ukuze kuqiniswe i-passive oxide, kanye ne-epoxy-polyester hybrid coating elinganiselwe ku-ISO 12944 C5-M (izinga lokucwiliswa olwandle). Ezimweni ezimbi kakhulu—njengamapayipi egesi ewuflue noma imigudu ye-desulfurization—ahlanganisa ama-titanium alloy impeller (iBanga lesi-2 noma iBanga lesi-7), ahlolwe ku-ASTM B348 isivuno esiqinile >345 MPa kanye nezinga lokugqwala elingu-<0.025 mm/ngonyaka ngo-10% H₂SO₄ ku-6% H₂SO₄. Akukho ukunamathela "okulingana-konke". Ukucaciswa kwemephu ngakunye kuya kukhemistri yesayithi langempela-hhayi ukuqagela kwelebhu.
Ukusebenza Komhlaba Wangempela Kudinga Ngalé Kokumelana Nokugqwala
Ukumelana nokugqwala kukodwa kusho okuncane uma ifeni ingakwazi ukuqhubeka nokusebenza. Sihlole ukufakwa komhubhe okungu-12 lapho abalandeli baphumelele khona ukuhlolwa kwesifutho sikasawoti kodwa kwehlulekile ukuqinisekiswa kwenkundla—ngoba ukudlidliza kukhuphuke ngo-72 Hz ngenxa yama-titanium blades angalingani, noma ngenxa yokuthi ukunwetshwa kokushisa okushisayo kungqubuzana nokuqhekeka kwezimpawu ze-epoxy phakathi no-40°C wamabhayisikili wansuku zonke. UZibo Hongcheng ukhuluma ngalezi zindlela zokwehluleka ezifihliwe:
- Ukulinganisa okunamandla ku-ISO 1940 G2.5—hhayi i-G6.3—iqinisekisiwe ngaphansi komthwalo, ayisebenzi
- Isinxephezelo sokunweba okushisayo kumafreyimu afakwayo, kusetshenziswa amashimu e-bimetallic emhubheni ahlanganisa -20°C kuya +65°C
- I-geometry yophawu iqinisekisiwe ngokumelene nemijikelezo yengcindezi engu-10⁵ (ukulingisa iminyaka engu-20 yokufaka umswakama)
- I-motor insulation ilinganiselwa ku-F-class (155°C), enokwembozwa okuhlelekile kumawindings wokumelana nokungenwa komswakama
Abalandeli babo bochungechunge lochungechunge lwe-FBD basebenza ngokuqhubekayo ku-4,500 Pa static pressure kanye nokugeleza okungu-120,000 m³/h—ngaphandle kokwehliswa kwemajini yokugqwala. Lokho kungenxa yokuthi ukulawulwa kokugqwala kugxilwe ekwakhiweni kwemishini, akuboshiwe njengokucatshangelwa kwamuva.
Ukwenza Ngokwezifiso Okufana Neqiniso Lesayithi—Hhayi Amashidi Ekhathalogi
“Ukumelana nokugqwala” kusho izinto ezihlukene emgodini wemayini yamalahle ngokumelene nomhubhe ongaphansi komhlaba uma kuqhathaniswa nomgudu wokuhlanza amanzi angcolile. Abanye abahlinzeki banikeza izinketho ezintathu zokuhlanganisa futhi bakubize ngokwezifiso. UZibo Hongcheng uphatha iphrojekthi ngayinye njengenselelo yobunjiniyela bezinto zokwakha. Bacela idatha eqondene nesayithi: i-pH yamasampula e-condensate, amalogi okugxilisa ingqondo e-SO₂, i-chloride ion ppm emanzini okugeza, ngisho namajika amazolo esizini. Bese bekhetha—hhayi ukusho.
Isibonelo: umhubhe oseduze nechweba lase-Qingdao udinga ukumelana ne-NaCl aerosol *kanye* nokonakaliswa kwe-UV kusuka ezigabeni zasemini. I-epoxy evamile iphuzi futhi iqoshiwe. Isixazululo sabo? Ijazi eliphezulu le-fluoropolymer phezu kwe-primer enothe nge-zinc, elisetshenziswa ngamakhanda afutha irobhothi okulawula ukujiya okungu-±5 μm. Isikhathi sokulethwa: amaviki angu-6—hhayi angu-12. Akukho ukuyekethisa ekutholeni isitifiketi: wonke amayunithi aphethe izimpawu ze-CE, CCC, ne-ATEX Zone 1/21 lapho kudingeka khona. Ukwenza ngokwezifiso akusho ukuhamba kancane. Kusho ukufaneleka ngenjongo, okuqinisekisiwe ngaphambi kokuthunyelwa.
Inani Lesikhathi Eside Liqala Ngokufaka—futhi Liyaqhubeka Ngemva Kokugunyazwa
Umlandeli wemhubhe omelana nokugqwala ukhokha onyakeni wesithathu—hhayi unyaka wokuqala. I-ROI yayo ivela ngesikhathi sokuphumula esigwenyiwe: akukho ukuvalwa okungahleliwe kokushintshwa kwe-blade, akukho ukubuyisela emuva kwezimoto eziphuthumayo ngenxa yokungena komswakama, akukho ukuqiniswa kwesakhiwo sabakaki abakhuphukayo. Kodwa inani lincike ekusetshenzisweni okulungile. I-Zibo Hongcheng inikeza amakhithi okufaka alinganiselwe ku-tunnel geometry—hhayi amaphakethe wehadiwe ajwayelekile. Onjiniyela babo baqinisekisa imininingwane ye-torque ye-anchor ngokumelene nokuminyana kwe-substrate (ibanga likakhonkolo, amandla ebhondi ye-shotcrete), lungisa ama-engeli ekhoni yokungena kumaphrofayili akhona we-duct turbulence, futhi aqinisekise izibambiso zokundindizela zokuhlukaniswa kwamaza azwakalayo angaphansi kuka-12 Hz.
Ngemva kokufakwa, balandelela ukusebenza ngezinzwa ze-IoT abazikhethela—ukuqapha i-delta enezinga lokushisa, ama-harmonics amanje, nokuphambuka kokugeleza komoya ngokumelene nesisekelo. Uma idatha ibonisa ukwehla kokusebenza kahle okungu-3.2% phakathi nezinyanga eziyisithupha, ithimba labo lixilonga ukuthi liyonakele yini, liqala ukugqwala, noma linwebeka ibhande lokushayela—ngaphambi kokuthi libe ukwehluleka. Lena akuyona isevisi. Kuwukuqhubeka kokusebenza okwakhelwe ngaphakathi.
Emihubheni lapho ukungena komoya kungelula khona—ukuphepha kwempilo—a ifeni yomhubhe ekwazi ukumelana nokugqwala kumele uthole igama layo nsuku zonke. Hhayi lab. Hhayi ephepheni. Kumaqiniso aswakeme, asebenza ngamakhemikhali, ajwayele ukudlidliza wengqalasizinda engaphansi komhlaba. I-Zibo Hongcheng Fan Co., Ltd. yakha abalandeli abaphumelela lokho kuhlolwa-hhayi kanye, kodwa iminyaka eyishumi nanhlanu. Ngoba ukungena komoya okuhlala njalo akuqali ngemininingwane yokugeleza komoya. Kuqala ngezinto ezinqabayo ukuzinikela.
