Forward Curved Motorized Impeller
Titafotokozera kuchuluka kwa kuthamanga kwa voliyumu komwe timafunikira, kaya ndikupereka mpweya wabwino kapena kuzizira kozizira, tifunika kuphatikiza izi ndi kukana kuyenda komwe fan angakumane nayo pakugwiritsa ntchito.Kuthamanga kwa voliyumu, (mu m3 / hr) ndi kupanikizika (mu Pascals - Pa), zimaphatikizidwa kuti zikhale malo omwe amawombera ayenera kugwira ntchito.Ndikofunikira kuti tisankhe chofanizira chomwe mawonekedwe ake amakwaniritsa ntchito yofunikira kapena pafupi ndi nsonga yamphamvu kwambiri.Kugwiritsa ntchito faniyo pachimake chake kumachepetsa kugwiritsa ntchito mphamvu komanso phokoso lochokera ku fan pomwe ikupereka magwiridwe ofunikira.
Kodi Forward Curved Centrifugal Fan imagwira ntchito bwanji?
Dzinalo, 'Centrifugal Fan' limachokera ku mbali ya mayendedwe ndi momwe mpweya umalowera ku choyikapo molowera ku axial kenako ndikutuluka kuchokera kunja kwa fani.Kusiyana kwa kayendedwe ka kayendedwe kake pakati pa fani ya kutsogolo ndi kumbuyo yokhotakhota ya centrifugal ndiko kumene mpweya umatuluka mu circumference circumference.Ndi cholowera chakumbuyo chokhotakhota, mpweya umatuluka munjira yozungulira pomwe mpweya wokhotakhota wakutsogolo umatuluka mozungulira kuchokera kuzungulira kwa fani.
Chokupiza chapatsogolo chopindika cha centrifugal chimadziwika ndi mawonekedwe ake a cylindrical ndi masamba ang'onoang'ono ambiri pa circumference ya choyikapocho.Muchitsanzo chomwe chili pansipa, faniyo imazungulira molunjika.
Mosiyana ndi cholowera chakumbuyo chokhotakhota, cholowera chakutsogolo chopindika chimafuna nyumba yomwe imatembenuza mpweya wothamanga kwambiri kusiya nsonga za tsamba la choyikapocho kukhala mphamvu yotsika yokhazikika.Maonekedwe a nyumbayo amawongoleranso mpweya wopita kumalo otuluka.Mtundu woterewu wa nyumba za fan umadziwika kuti mpukutu;komabe, itha kutchulidwanso ngati nyumba ya volute kapena sirocco.Poyika cholowera chakutsogolo chokhotakhota m'nyumba ya mipukutu, nthawi zambiri timachitcha ngati chowombera chopindika kutsogolo.
Pali mitundu iwiri ya zokuzira zomwe zimagwiritsa ntchito chowongolera chamoto chopindika monga zikuwonekera pansipa…
Chowombera cholowera chimodzi kumanzere, chimakoka mpweya kuchokera mbali imodzi ya nyumbayo kudzera panjira yozungulira ndikuchilozera kumalo olowera, (wowona apa ndi flange yokwera).Chowuzira cholowera pawiri chimakhala ndi mipukutu yotakata yomwe imakokera mpweya kuchokera mbali zonse ziwiri za mpukutuwo ndikuufikitsa kumalo otuluka.
Monga momwe zimakupizira kumbuyo kokhotakhota kwa centrifugal, mbali yoyamwa ya chiwongolerocho imakoka mpweya kuchokera pakati pa faniyo yomwe imapangitsa kusintha kwa kayendedwe ka mpweya pakati pa cholowera ndi kutuluka kwa 90o.
Mafani a Mafani
Malo abwino ogwirira ntchito kwa fan yokhota kumapeto kwa centrifugal ndi pamene ikugwira ntchito mothamanga kwambiri.Fani yokhotakhota kutsogolo imagwira ntchito bwino ngati kupanikizika kwakukulu kumadutsa kutsika kwamphamvu kumafunika.Grafu yomwe ili pansipa ikuwonetsa malo abwino kwambiri ogwirira ntchito…
Kuthamanga kwa voliyumu kumakonzedwa motsatira X-axis ndipo kupanikizika kwadongosolo kumapangidwira pa Y-axis.Pamene palibe kukakamizidwa mu dongosolo, (wokupiza akuwomba momasuka), kutsogolo kokhotamira kwa centrifugal fan kumatulutsa kuthamanga kwakukulu kwa voliyumu.Monga kukana kuyenda kumagwiritsidwa ntchito ku mbali ya kuyamwa kapena kutulutsa mpweya wa fan, kuchuluka kwa voliyumu kumatsika.
Chenjezo liyenera kuchitidwa posankha chowulutsira kutsogolo chokhotakhota kuti chigwire ntchito pazovuta zotsika komanso kuthamanga kwamphamvu kwambiri.Panthawiyi, choyipitsacho chikugwira ntchito mu malo a aerodynamic mofanana ndi fan ya axial yomwe ikugwira ntchito pamtunda wa chishalo chake.Panthawiyi phokoso ndi kugwiritsa ntchito mphamvu zidzakhala pachimake chifukwa cha chipwirikiti.
Kuchita bwino kwambiri kumakhala pamalo otchedwa bondo la khalidwe lopindika.Pakadali pano chiŵerengero cha mphamvu zotulutsa za fani (Volume flow (m3/s) x Static Pressure Development (Pa) ndi mphamvu yamagetsi (W) ndiyokwera kwambiri ndipo kukakamiza kwa mawu kopangidwa ndi fani kudzakhala. Pamwamba ndi pansi pa kuchuluka kwa momwe amagwirira ntchito bwino, kuthamanga kwa fani kumakhala kwaphokoso kwambiri ndipo magwiridwe antchito amatsika.
Ubwino wogwiritsa ntchito cholowera chimodzi chakutsogolo chopindika ndi chakuti chimakhala ndi mawonekedwe otsetsereka.Izi ndizofunikira makamaka pamakina omwe amafunikira kusefera kosasintha.Pamene mpweya ukudutsa mu particulate fyuluta fyuluta amamanga mpweya fumbi ndi mungu, bwino kalasi ya kusefera ang'onoang'ono particles womangidwa ndi fyuluta.M'kupita kwa nthawi fyulutayo idzadzaza kwambiri ndi dothi ndi zinyalala zomwe zimakhala ndi zotsatira zomwe zimafunika kuti zikhale zovuta kuti zipereke mpweya womwewo.Kugwiritsa ntchito chopukutira chokhala ndi mapindikidwe otsetsereka pankhaniyi kumatanthauza kuti fyulutayo ikatsekeka kwambiri, kuthamanga kwa voliyumu kumakhalabe kosasintha pomwe kukakamiza kudutsa fyuluta kukukulirakulira.
Ubwino wogwiritsa ntchito chopondera chakutsogolo chopindika chapawiri ndikuti kuchokera pa chowuzira chaching'ono chimatha kutulutsa kutulutsa kwamphamvu kwambiri.Kugwirizana ndi kugwiritsa ntchito chowombera cholowera kawiri ndikuti kumakhala ndi kutsika kwapang'onopang'ono kutanthauza kuti chitha kugwira ntchito ndi machitidwe ocheperako.
Zosankha zoyika
Monga tanena kale, cholowera chakutsogolo chokhotakhota chimatulutsa mpweya wothamanga kwambiri pansonga za tsamba lomwe limayenera kuwongoleredwa ndikuchedwetsedwa kuti lisinthe kukakamiza kosunthika kukhala static pressure.Kuti tichite izi, timapanga mpukutu mozungulira chopondera.Maonekedwewa amapangidwa ndi chiŵerengero cha mtunda kuchokera pakati pa chopondera kupita ku fani.Monga momwe zimakupizira kumbuyo zokhotakhota zimalimbikitsidwanso kukhala ndi kaphatikizidwe kakang'ono pakati pa mphete yolowera ndi pakamwa pa chopondera.Malingaliro onse okwera akuwonetsedwa pazithunzi pansipa…
M'mimba mwake wa mphete yolowera ingolola kusiyana pang'ono pakati pa choyikapo ndi mphete kuti tipewe kuzunguliranso kwa mpweya.
Zofunikira pakuwonjezera - kuwongolera
Ndikofunika kuwonetsetsa kuti pali chilolezo chokwanira pa kuyamwa ndi mbali ya fan ...
Kusakwanira kwa chilolezo kumbali yokoka ya fan kumawonjezera liwiro la kulowa komwe kungayambitse chipwirikiti.Chisokonezochi chidzawonjezedwa pamene mpweya umadutsa mu choyimitsa chomwe chimapangitsa kuti kusuntha kwa mphamvu kuchokera ku fan fan kupita ku mpweya kukhale kopanda mphamvu, kumapangitsa kuti phokoso likhale lopanda phokoso komanso kuchepetsa mphamvu ya fan.
Malangizo okhazikika pazolowera ndi kutulutsa ndi:
Inlet Side
- Palibe chotchinga kapena kusintha komwe kumayendera mkati mwa 1/3rd kutalika kwa fani kuchokera pakulowera kwa fani
Chidule cha nkhaniyi - Chifukwa Chiyani Musankhe chowotcha chopindika chapatsogolo cha centrifugal?
Pamene ntchito yofunikira igwera m'dera la kupanikizika kwadongosolo lapamwamba poyerekeza ndi kutsika kwa voliyumu pa chikhalidwe cha fani cholowera kutsogolo chokhotakhota cha centrifugal fan chiyenera kuganiziridwa.Ngati kufunikira kwa pulogalamuyo ndikuyenda kwamphamvu kwambiri mu emvulopu yamalo oletsedwa, chowotcha chapawiri chopindika chapakati chiyenera kuganiziridwa.
Fanizo liyenera kusankhidwa mkati mwamtundu wake wabwino kwambiri womwe uli pamalo omwe amadziwika kuti bondo la mayendedwe ake.Mfundo yogwira ntchito bwino kwambiri ili pafupi ndi malire othamanga kwambiri pamtundu wa fani pomwe ikugwiranso ntchito mwakachetechete.Kugwira ntchito kunja kwa njira yabwino kwambiri (pamtunda wothamanga kwambiri) kuyenera kupewedwa chifukwa chipwirikiti ndi mphamvu ya aerodynamic ya tsamba la impeller pazigawozi zidzapanga phokoso ndipo choyimitsacho chidzakhalanso chikugwira ntchito mu aerodynamic stall.Pazovuta zotsika komanso kuthamanga kwamphamvu kwambiri kuyenera kuganiziridwa pa kutentha kwa injini yomwe ikunyamula chifukwa pali kuthekera kwa kutentha kwamoto.
Mpweya womwe uli kumbali yakulowera kwa chopondera uyenera kukhala wosalala komanso laminar momwe mungathere.Kuti muwonjezere kuchita bwino, cholozera cha 1/3 cha mainchesi chiyenera kuloledwa pa cholowera cha fan.Kugwiritsa ntchito mphete yolowera (Inlet nozzle) yomwe imadutsana ndi cholowera kumathandizira kuthetsa kusokonezeka kwa mpweya mpweya usanakokedwe kudzera pa fani, kuchepetsa phokoso loyambitsa chipwirikiti, sungani kugwiritsa ntchito mphamvu pamalo ogwirira ntchito ndikuchepetsa mphamvu.
Mawonekedwe otsetsereka, kukhathamiritsa kwamphamvu kwa zoombera zolowera kamodzi komanso kutulutsa kwamphamvu kwa zowuzira zolowera pawiri kumatanthauza kuti chowozera chamtsogolo ndi njira yothandiza kuiganizira pamayimidwe osiyanasiyana.
