Y4-73-NO18D Centrifugal Fan, yokhala ndi injini ya 250KW. Liwiro lozungulira ndi 960 revolutions pamphindi. Chokupizacho chimakhala ndi chothandizira mbale zachitsulo, zomwe zimapangitsa kuti kuyika ndi kumanga kukhala kosavuta. Chokupiza ichi ndi chopingasa chogawanika chamtundu. Nyumba ya fan ili ndi mabowo owonera.
Mafani a centrifugal ochotsa fumbi amagwiritsidwa ntchito m'mafakitale osonkhanitsira fumbi ngati ma centrifugal ventilators. Zotsatirazi zifotokoza mfundo zawo zogwirira ntchito, kapangidwe kake, magwiridwe antchito, ndi madera ogwiritsira ntchito:
Mfundo Yogwirira Ntchito
Gawo Lolowa: Mpweya wodzaza fumbi umalowa mu fani kudzera pa doko lolowera ndikuthamanga pansi pa kusinthasintha kothamanga kwa chopondera, kupeza mphamvu ya kinetic.
Gawo la Centrifugal Separation Stage: Pansi pa zitsulo zotulutsa mpweya, mpweya umatulutsa mphamvu ya centrifugal, kuchititsa kuti tinthu tating'ono tiponyedwe ku khoma lamkati la casing chifukwa cha inertia, ndiyeno lowetsani fumbi, monga zosefera za thumba kapena otolera fumbi.
Gawo la Exhaust: Gasi woyeretsedwa amatulutsidwa kudzera pa doko la fan, ndikumaliza ntchito yochotsa fumbi.
Mitundu ya Ma Fani Ochotsa Fumbi a Centrifugal
1. Chokupizacho chimapangidwa ngati mtundu umodzi woyamwa. Kukula kumayambira pa 2.8 mpaka 29.
2. Mtundu uliwonse wa fan ukhoza kupangidwanso mozungulira kumanzere kapena kumanja. Kuchokera kumbali ya galimoto, ngati choyikapo chimayenda mozungulira, chimatchedwa fani yamanja, yomwe imatanthauzidwa ndi "kumanja"; ngati motsatira koloko, imatchedwa fan yakumanzere, yomwe imatanthauzidwa ndi "kumanzere".
3. Ngodya ya kutulutsa kwa fan ikuwonetsedwa ndi ngodya ya kutulutsa kwa casing.
4. Njira zoyendetsera mafani ndi awa:
Mtundu wa A: Kulumikizana mwachindunji ndi injini
B-mtundu ndi C-mtundu: Lamba galimoto
D-mtundu: Coupling drive
Mapangidwe Apangidwe a Centrifugal Ventilators Centrifugal Fan
Impeller: Zomwe zimapangidwira ndi masamba opindika kumbuyo, opangidwa kuchokera ku zitsulo zolimba kwambiri zowotcherera kapena zolumikizidwa palimodzi, zomwe zimapereka kukana kovala bwino komanso magwiridwe antchito aerodynamic, kuchepetsa kugwiritsa ntchito mphamvu moyenera. Zotulutsa zina zimakutidwa ndi zinthu zosavala kapena kuthandizidwa ndi ma weld over over kuti agwirizane ndi malo okhala ndi fumbi lambiri.
Fani yamtundu wa A imakhala ndi casing, doko lolowera, chowongolera, chimango chothandizira, chitseko chosinthika (kutengera zosowa za makasitomala), ndi mota, pakati pa ena. Mitundu ya B, C, ndi D imakhalanso ndi zida zotumizira. Mafani amayesedwa kwambiri asanachoke kufakitale, ndi matalikidwe akukumana ndi miyezo ya dziko. Kwa zitsanzo pamwamba pa kukula kwa 18 #, chimango chonse chothandizira chimagulidwa malinga ndi zofuna za makasitomala (nthawi zambiri amagwiritsa ntchito maziko a konkire). Chosungiracho chimapangidwa ndi mbale zachitsulo, zomwe zimapereka kudalirika kwamphamvu, zomwe zimapezeka mumitundu yofunikira kapena yotseguka, ndipo zomalizazi zimathandizira kukonza. Zitsanzo zomwe zili pansi pa kukula 14 # ndizofunika kwambiri, pamene zomwe zili pamwamba pa 14 # nthawi zambiri zimakhala zotseguka. Choyikacho chimakhala ndi masamba, diski yakutsogolo yokhotakhota, ndi chimbale chakumbuyo chakumbuyo, cholumikizidwa pamodzi. Iyenera kukhala yokhazikika komanso yokhazikika kuti iwonetsetse kuti imasinthasintha komanso imagwira ntchito bwino. Gawo lopatsirana limaphatikizapo shaft yayikulu, nyumba zokhala, zozungulira, ndi pulley (kapena coupling), zokhala ndi zida zoziziritsira madzi kuti ziziziziritsa ma bere ndikuwonjezera moyo wawo. Doko lolowera limapangidwa kuchokera ku mbale zachitsulo kukhala mawonekedwe owoneka bwino, ndikupanga mawonekedwe osinthika omwe amayikidwa pambali pa fani, yokhala ndi gawo lopindika motsatira njira ya axial, zomwe zimalola kuti mpweya ulowe mu choyimitsa bwino ndikutayika pang'ono. Khomo losinthika limayikidwa kutsogolo kwa doko lolowera, kuwongolera kuchuluka kwa mpweya ndikusunga liwiro la fan (kupanikizika). Chothandizira chonsecho chimapangidwa ndi chitsulo chachitsulo ndi mbale zachitsulo, kuonetsetsa kuti zomangamanga zolimba, zokhazikika komanso zolimba. Galimoto imagwiritsa ntchito ma mota apamwamba kwambiri okhala ndi ma cores amkuwa, omwe nthawi zambiri amakhala osasintha ku Giredi 3 zamagetsi zamagetsi. Zosankha zosintha mwamakonda zimaphatikiza ma motors otembenuza pafupipafupi, ma mota osaphulika, ndi ma mota okhala ndi mphamvu zopatsa mphamvu kuposa Giredi 2.
Mawonekedwe a mafani a centrifugal: Centrifugal Fan
Kupulumutsa mphamvu mwamphamvu kwambiri: Mapangidwe okhathamiritsa aerodynamic amakwanitsa kupitilira 85%, kupulumutsa mphamvu 10% -20% poyerekeza ndi mafani wamba.
Kukana kuvala kwakukulu: Choyimitsacho chimatha kukutidwa ndi zinthu zosavala kapena kuthandizidwa ndi ma weld, okhoza kupirira malo okhala ndi fumbi komanso kukulitsa moyo wautumiki wa fan.
Phokoso lochepa: Makona a masamba okongoletsedwa bwino ndi ma casing amapangitsa kuti phokoso lizikhala lochepera 85dB(A), zomwe zimathandizira kuti ntchito ziziyenda bwino.
Kukonza kosavuta: Chosungiracho nthawi zambiri chimapangidwa kuti chiphatikize, kuwongolera kuyang'anira ndikusintha chowongolera, kuchepetsa ndalama zokonzera komanso zovuta.
