Isabelo semakethe sabalandeli be-axial flow
The abalandeli be-axial flow Imakethe ihlukaniswe ngejubane (eliphansi, eliphakathi, eliphakeme), usayizi, uhlelo (ukupholisa, irediyetha, umoya omncane), uhlobo (DC, AC, EC), abasebenzisi bokugcina (izimboni, ezentengiselwano, zokuhlala), kanye nesifunda. Le makethe isaqhubeka nokukhula okuphawulekayo phakathi neminyaka njengoba abakhiqizi abafana ne-Sofasco Fans kanye ne-Hidria begxila ekuthuthukisweni kwemikhiqizo emisha kanye nokuqanjwa kabusha. Iningi labadlali bemakethe lihlanganisa ubuchwepheshe obuyinkimbinkimbi ukuze balondoloze inzuzo yabo yokuncintisana emakethe yomhlaba.
Abalingani be-Insight ibonise inani lemakethe yomhlaba yabalandeli be-axial flow I-USD 2,301.4 million ngo-2020. Bekulindeleke ukuthi ikhule ngezinga lokukhula elihlanganisiwe lonyaka 4.3% ukufinyelela I-USD 3,219.8 million ngo-2028. Isici esibalulekile sokuqhuba lokhu kukhula sizogxilwa ekusetshenzisweni okwandayo kwabalandeli be-axial flow ezimbonini ezihlukahlukene njengezimayini, amakhemikhali, kanye ne-electronics.
Isifunda sase-Asia Pacific, esinamazwe afana ne-India, i-China, ne-Australia, sibhalisa amathuba emakethe amakhulu kakhulu kubalandeli be-axial flow. Lokhu kungenxa yentuthuko eqhubekayo yezimboni ezidinga lezi zisetshenziswa. Ingxenye enesivinini esimaphakathi ithole isabelo semakethe esikhulu kunazo zonke ngo-2020 futhi kulindeleke ukuthi ikhule ngokulinganayo ngesivinini esisheshayo ngesikhathi sokubikezela.
Ingxenye yokupholisa nesiqandisi ibalwe ngesabelo esikhulu kunazo zonke ngohlelo lokusebenza, kuyilapho ingxenye yokungenisa umoya izokhula ngokushesha kakhulu ngesikhathi sokubikezela.
Izinhlobo zabalandeli be-axial flow
1. Vane axial fans
Abalandeli be-Vane axial amafeni ayimishini asetshenziselwa ukungena komoya kanye nokujikeleza komoya ezindaweni zezentengiselwano nezimboni. Idizayini yabo eyinhloko iyihabhu enamathiselwe ngama-vanes ama-angled amaningana noma izindwani. Lapho ifeni ivuliwe, ihabhu nama-blade ayazungeza, adweba emoyeni ngesiphepho bese eyiphushela ngaphandle. Lawa mafeni angahambisa ivolumu enkulu yomoya ngesivinini esikhulu ezinhlelweni ezidinga ukucindezela okuphezulu okumile kanye namazinga okugeleza. Izicelo zifaka imibhoshongo yokupholisa, amasistimu okungenisa umoya, nezinhlelo zokupholisa umoya.
2. Abalandeli be-axial be-Tube
Abalandeli be-axial tube zenzelwe ukuhambisa umthamo omkhulu womoya ezindaweni zezimboni nezohwebo ukuze zinikeze umoya omncane. Anama-motor nama-impellers, afakwe kumashubhu angama-cylindrical. I-impeller inehabhu exhunywe izindwani ezizungezayo ukuze zidonse umoya kufeni ngeshubhu. Lo moya oqoqiwe ukhishelwa ngaphandle kweshubhu ngendlela ethile ngepayipi noma i-ventilation shaft. I-impeller yakhelwe ukunciphisa isiyaluyalu futhi yandise ukugeleza komoya. Lokhu kuvumela i-tube abalandeli be-axial ukuphatha amazinga aphezulu okugeleza futhi ngaleyo ndlela asebenza kahle.
3. Abalandeli be-propeller axial
Abalandeli be-propeller axial sebenzisa isethi yama-blades axhunywe kuhabhu emaphakathi ukuze unikeze ukugeleza komoya. Ezimbonini nasezimbonini zezentengiselwano, asusa ukushisa noma intuthu, ajikeleze umoya, futhi anikeze umoya omncane. Amafeni we-axial ophephela adonsa umoya ngokulandelana ngezinti futhi ngokuhambisana ne-axis yesiphepheli ukuze awuqhubekisele phambili. Lokhu kudala izindawo ezinengcindezi ephansi ngemuva kwefeni, eqoqa umoya owengeziwe ovela endaweni eseduze okuholela ekugelezeni komoya okuqhubekayo.
Abalandeli be-propeller axial basetshenziswa ekupholiseni izikhala ezinkulu zezimboni njengezindawo zokugcina izimpahla ukuze kuhlinzekwe komoya emagalaji okupaka kanye namakhishi okuhweba. Asetshenziswa kakhulu ekushiseni, ekungeniseni umoya, nasezinhlelweni zesimo somoya (HVAC) ukulawula izinga lokushisa nokuhlinzeka ngokujikeleza komoya.
Ungakhetha kanjani i-axial flow fan efanelekile
I-1. Intengo
Abalandeli be-axial flow banamanani ahlukene ngokuya ngezinto ezilandelayo. Usayizi wefeni uyithinta kakhulu intengo yayo. Ngokwesilinganiso, abalandeli abakhulu bavame ukubiza kakhulu kunabalandeli abancane. Kulokhu, ukukhetha kufanele kusekelwe esikhaleni esitholakalayo kanye nokugeleza komoya okudingekayo. Uhlobo lwemoto, kungakhathaliseki ukuthi i-AC noma i-DC, lunquma amanani abalandeli. Amamotho e-DC abiza kakhulu kunamamotha e-AC njengoba ekhulisa ukusebenza kahle kwamandla nokulawula isivinini.
Ngaphezu kwalokho, ikhwalithi yezinto ezibonakalayo esetshenziswa ekwakhiweni kwefeni izothinta intengo yayo. Lokhu kungenxa yokuthi kuthinta ukusebenza kwefeni nokuqina, futhi ngaleyo ndlela izinto zekhwalithi ephezulu zinyusa intengo. Izindleko ezimaphakathi zabalandeli bokugeleza kwe-axial abanosayizi omncane bendawo yonke 6-8 amayintshi ububanzi yi USD 20-50. Amafeni amakhulu okugeleza kwe-axial anobubanzi be- 12-24 amayintshi izindleko nxazonke USD 100-500.
2. Izinga lomsindo
Abathengi kufanele bakhethe isilinganiso esiphansi se-decibel (dB) lapho bethola abalandeli. Ngokwesilinganiso, abalandeli abanesilinganiso se-dB cishe I-50 noma ngaphansi zibhekwa zithule. Ubukhulu babalandeli buthinta izinga lomsindo, njengoba abalandeli abakhulu bekhipha umsindo omncane kunabalandeli abancane ngoba behambisa umoya omningi ngesivinini esiphansi, okwehlisa umsindo. Abalandeli bejubane eliphansi bakhiqiza umsindo omncane kunabalandeli bejubane eliphezulu.
Abalandeli abanama-engeli noma ama-curved blades bathule kunabalandeli abanezinsimbi eziqondile. Futhi, abalandeli abanama-DC motors baphumela ekudlidlizeni okuncane nomsindo kunamamotho e-AC. Okokugcina, abalandeli abakhiwe ngezinto ezisezingeni eliphezulu bayabiza kodwa banezici zokunciphisa umsindo.
3. Ijubane
Ngokucabangela isivinini, abalandeli abanokuguqulwa okuphezulu ngomzuzu (i-RPM) izilinganiso ezifanele kakhulu. Abalandeli bejubane eliphezulu bangakwazi ukuhambisa umoya kalula nakuba bengase babe nomsindo. Abathengi kufanele bakhethe abalandeli abanezinketho zokulawula isivinini njengesilawuli sePulse Width Modulation (PWM) noma isilawuli sabalandeli. Ngokuvamile, abalandeli be-voltage ephakeme banikeza isivinini esiphezulu; ngakho-ke, i-voltage kufanele ifane nomthombo wamandla. Futhi, imiklamo ye-engeli noma i-curved blade inikeza ukusebenza kahle ngokugeleza komoya okuphezulu ngesivinini esiphansi.
Ngokwesilinganiso, amafeni amancane okugeleza kwe-axial ane- 6-8 amayintshi I-diameter ine-RPM yokuzungeza 1500-4000. The 12-24 amayintshi abalandeli be-diameter banganikeza isivinini esingaba 500-2500 RPM. Ngakolunye uhlangothi, abalandeli be-axial flow ngesivinini esikhulu ezinhlelweni ezahlukahlukene zezimboni kufanele bafinyelele 10,000 RPM noma isivinini esiphezulu.
I-4. Ukuqina
Abanye abalandeli emakethe banezici ezengeziwe eziqinisekisa ukuthi bangasebenza kahle ezindaweni ezinokhahlo. Isibonelo, ama-coatings okuvikela, ama-bearings avaliwe, nezilinganiso eziphezulu ze-IP. Amafeni akhiwe ngezinto zekhwalithi ephezulu njengepulasitiki enomthelela ophezulu nezinsimbi angamelana nokuguga kalula. Izinto zokwakha zingamelana nokulimala okuvela kumswakama, uthuli, namazinga okushisa aphezulu kakhulu.
Futhi, isilinganiso se-Ingress Protection (IP) sibonisa izinga lokuvikela umlandeli analo emanzini nothuli. Kulokhu, abalandeli abazosetshenziswa endaweni ehlanzekile, eyomile, nengaphakathi endlini badinga isilinganiso se-IP20. Nokho, isilinganiso esincane se-IP44 siyelulekwa kubalandeli esizosetshenziswa ezindaweni eziswakeme.
5. Ukusebenza kahle
Abathengi kufanele bahlole imininingwane yomkhiqizo yabalandeli abahlukahlukene ukuze baqinisekise ukuthi bahlangabezana nezidingo zabo zokusebenza kahle. Abalandeli abakhulu basebenza kahle kakhulu kunabalandeli abancane njengoba behambisa umoya omningi kuyilapho bedla amandla amancane. Abanye abalandeli baqukethe isici sokulawula isivinini. Lokhu kwenza abathengi bakwazi ukukhetha isivinini sabalandeli esifana nokugeleza komoya okudingekayo.
Futhi, abalandeli bezimoto ze-DC basebenza kahle kakhulu kunabalandeli bezimoto ze-AC ngoba badinga amandla amancane. Ukwengeza, ama-blade agobile kubalandeli asebenza kahle kakhulu ngenxa yekhono lawo lokunikeza ukugeleza komoya okuphezulu kuyilapho esebenza ngesivinini esiphansi.
Isifinyezo
Embonini yabalandeli be-axial flow, ukubuyekezwa kwamakhasimende kungaqinisekisa ukuthi abathengi bathola ifeni ehlangabezana nezidingo zabo. Ngokucabangela izici ezishiwo kumhlahlandlela ongenhla, abathengi bangakhetha ifeni eletha ukusebenza okufunayo ngempilo ende yesevisi. Ukuze ufunde kabanzi, futhi uphequlule ukufakwa kuhlu kwabalandeli be-axial flow abasebenzayo, vakashela Cooig.com.
