Mfundo yogwirira ntchito ya cylindrical blower
Mfundo yogwirira ntchito ya kuwombera centrifugal ndi ofanana ndi mpweya wa centrifugal, koma kuponderezana kwa mpweya nthawi zambiri kumachitika kudzera mwa ma impeller angapo ogwira ntchito (kapena magawo angapo a） motsogozedwa ndi mphamvu ya centrifugal. Wowomberayo ali ndi rotor yomwe imazungulira mwachangu kwambiri. Mphamvu yoyendetsera mpweya imapangitsa kuti mpweya utuluke kutuluka kwa zimakupiza pamzere wolumikizana ndi kabokosi wokhala ndi mawonekedwe ake. Mpweya wabwino umadzazidwa ndikulowa pakatikati pa nyumbayo .
Ntchito mfundo single liwiro liwiro centrifugal zimakupiza ndi: injini ndi liwiro kasinthasintha kutsinde kuyendetsa impeller, ofananira mpweya ndi imports pambuyo kulowa liwiro onsewo onsewo impeller mu otaya zozungulira ndi inapita patsogolo, ndiyeno kuthamanga M'mimbamo kukula, kusintha otaya mayendedwe ndi kuchepetsedwa, kuchepa kwake kudzakhala pakuyenda kothamanga kwambiri kwa mpweya ndi mphamvu zamagetsi zamagetsi zamagetsi (kuthekera kwa mphamvu), zimapangitsa kuti zimakupangitsani kutumiza kunja kukakamizidwa.
Kunena mwamawonekedwe, kuthamanga-kofikira kwa mawonekedwe a kuwombera centrifugal ndi mzere wowongoka, koma chifukwa chotsutsana ndi mikangano ndi zina zotayika mkati mwa fan, kuthamanga kwenikweni ndi kutsetsereka kwamakhotedwe pang'onopang'ono kumachepa ndikuwonjezeka kwa kutuluka, komanso kupendekeka kofananira kwa mphamvu kwa wokonda centrifugalimatuluka ndikuwonjezeka kwa kuyenda. Faniyo ikamathamanga mosathamanga, magwiridwe antchito a zimakupiza amayenda mothamanga. Malo ogwiritsira ntchito zimakupiza samadalira pakungogwira kwake kokha, komanso machitidwe amachitidwe. Pamene kulimbana kwa chitoliro kumawonjezeka, chitoliro chogwirira ntchito chimakhala cholimba.
Mfundo yayikulu ya zimakupiza Lamulo ndikuti mupeze momwe zinthu zikufunira pogwira ntchito posintha mawonekedwe a fanasi palokha kapena mawonekedwe a chitoliro chakunja.Ndikukula kopitilira muyeso kwaukadaulo, ukadaulo wa AC woyendetsa liwiro umagwiritsidwa ntchito kwambiri. Kudzera m'badwo watsopano wazinthu zamagetsi zoyendetsedwa bwino, kuyendetsa kwa zimakupiza kumatha kuwongoleredwa posintha liwiro la AC mota ndi chosinthira pafupipafupi, chomwe chingachepetse kuchepa kwa mphamvu komwe kumayambitsidwa ndimayendedwe am'mbuyomu.
Mphamvu yopulumutsa mphamvu yosinthira pafupipafupi:
Pomwe mpweya uyenera kuchepetsedwa kuchokera ku Q1 mpaka Q2, ngati njira yokhotakhota imagwiritsidwa ntchito, malo ogwirira ntchito amasintha kuchokera ku A mpaka B, kuthamanga kwa mphepo kumakulirakulira ku H2, ndipo shaft mphamvu P2 imachepa, koma osati yochulukirapo. Ngati kusintha kosinthira pafupipafupi kutengera, malo ogwirira ntchito a fan kuchokera pa A mpaka C. Zitha kuwonedwa kuti pokhapokha kuti voliyumu yomweyo ya mpweya Q2 yakhutira, kuthamanga kwa mphepo H3 kumachepa kwambiri ndipo mphamvu ichepetsedwa
P3 idachepetsedwa kwambiri. Kutaya mphamvu kwasungidwa △ P = △ Hq2 ndiyofanana ndi dera la BH2H3c. Kuchokera pakuwunika pamwambapa, titha kudziwa kuti kusintha kosintha pafupipafupi ndi njira yabwino yoyendetsera. Blower amatenga pafupipafupi kutembenuka malamulo, sangatulutse zina mavuto kuthamanga, mphamvu zopulumutsa zotsatira ndi chidwi, kusintha mpweya buku osiyanasiyana 0% ~ ~ ~ 100%, oyenera osiyanasiyana malamulo, ndipo nthawi zambiri pansi nthawi otsika katundu ntchito. Komabe, liwiro la zimakupiza likuchepa komanso mpweya utatsika, kuthamanga kwa mphepo kumasintha kwambiri. Lamulo lofanana la zimakupiza ndi ili: Q1 / Q2 = (N1 / N2), H1 / H2 = (N1 / N2) 2, P1 / P2 = (N1 / N2) 3
Titha kuwona kuti liwiro likachepetsedwa kufika theka la liwiro loyambirira, kuthamanga, kuthamanga ndi kutsinde kwa mphamvu yogwirira ntchito ikugwera mpaka 1/2, 1/4 ndi 1/8 yoyambirira, yomwe ndichifukwa chake malamulo osintha pafupipafupi amatha kupulumutsa magetsi. Malinga ndi mawonekedwe amachitidwe osinthira pafupipafupi, pokonza zimbudzi, thanki ya aeration nthawi zonse imasunga madzi okwanira 5m, ndipo wophulitsayo amafunika kuyendetsa kayendetsedwe kambiri mosiyanasiyana chifukwa cha kukakamizidwa kokhazikika. Pamene kuya kwakusintha kuli kwakukulu, kuthamanga kwa mphepo kudzagwa kwambiri, komwe sikungakwaniritse zomwe zikufunika. Pamene kusintha kwakuchepa kuli kochepa, sikungathe kuwonetsa zabwino zopulumutsa mphamvu, koma zimapangitsa kuti chipangizocho chikhale chovuta, ndalama za nthawi imodzi zawonjezeka. Chifukwa chake, malinga ndi kuti thanki ya aeration ya ntchitoyi iyenera kusunga madzi okwanira 5m, ndichachidziwikire kuti si koyenera kutsatira njira zosinthira pafupipafupi.
Chipangizo chowongolera cholowera chokhala ndi zida zili ndi zida zosinthira zowongolera Angle ndi cholowera chowongolera pafupi ndi cholowetsa chowomberacho. Udindo wake ndikupangitsa kuti mpweya uzizungulira usanalowe m'malo othamangitsira, ndikupangitsa liwiro lopindika. Tsamba lowongolera limazungulira mozungulira olowera ake. Kutembenuka kulikonse kwa tsamba kumatanthauza kusandulika kwa makina oyendetsera tsamba, kotero kuti kuwongolera kwa mpweya kumalowera m'malo opumira kumasintha.
Pamene kalozera tsamba unsembe ngodya 0 = 0 °, tsamba kalozera kwenikweni alibe mphamvu pa mpweya polowera, ndi mpweya udzayenda mu tsamba impeller mu njira zozungulira. Pamene 0 BBB 0 °, cholowa chowongolera cholowera chimapangitsa kuthamanga kwakanthawi kolowera mpweya kuthamangitsa О Angle motsatira njira yoyenda mozungulira, ndipo nthawi yomweyo, imakhudza kuthamanga kwa kuthamanga kwa mpweya. Kusinthaku kusanachitike komanso kupindika kumabweretsa kuchepa kwa mawonekedwe a fan, kuti asinthe momwe zinthu zikuyendera, ndikuzindikira kayendedwe ka fan. Mphamvu yopulumutsa mphamvu ya polowera kalozera vane malamulo.
Kuyerekeza mitundu yosiyanasiyana yamalamulo
Ngakhale kusintha kwakanthawi kosinthira kwamitundu yama centrifugal blower ndikutakata kwambiri, kumakhudza kwambiri kupulumutsa mphamvu, koma ndimadongosolo amachitidwe ndi zochepera, ndondomeko zosintha ndi 80% ~ 100% zokha, kuchuluka kwa mayendedwe osintha pang'ono, njira zosinthira pafupipafupi ndikuwongolera kusiyanasiyana kwamphamvu kosagwiritsa ntchito sikokulirapo, kotero njira yoyendetsera inverter, njira yopulumutsa mphamvu kuti isatuluke, itaya tanthauzo tanthauzo lake. Wowomberayo wokhala ndi njira yoyendetsera kayendetsedwe kake amatha kusintha voliyumu ya mpweya (50% ~ 100%) m'njira zokulirapo malinga ndi kusunga kotulutsira kosalekeza, kuti zitsimikizire kuti mpweya wabwino umasungunuka mu zimbudzi ndikupulumutsa mphamvu pang'ono. Chifukwa chake, wokonda kuthamanga kwambiri wa centrifugal yemwe ali ndi njira zowongolera zowongolera ayenera kusankhidwa ngati zida zosankhira ntchitoyi. Nthawi yomweyo, kuti muwonetsetse bwino kupulumutsa mphamvu, kwa fani yamphamvu kwambiri ya centrifugal, chisamaliro chiyeneranso kulipidwa posankha magalimoto othandizira, monga kugwiritsa ntchito 10kV mota wamagetsi ambiri, kumathandizanso kuchepetsa kugwiritsidwa ntchito kwamagetsi .
