Imatchedwa turbomachinery kuti isamutse mphamvu kupita ku madzi oyenda mosalekeza pogwiritsa ntchito mphamvu ya masamba pa impeller yozungulira kapena kulimbikitsa kuzungulira kwa masamba ndi mphamvu yochokera ku madzi. Mu turbomachinery, masamba ozungulira amagwira ntchito yabwino kapena yoipa pa madzi, kukweza kapena kuchepetsa kuthamanga kwake. Turbomachinery imagawidwa m'magulu awiri akuluakulu: imodzi ndi makina ogwirira ntchito omwe madziwo amatengera mphamvu kuti awonjezere mutu wa kuthamanga kapena mutu wa madzi, monga mapampu a vane ndi ma ventilator; inayo ndi prime mover, momwe madziwo amakulira, amachepetsa kuthamanga, kapena mutu wa madzi umapanga mphamvu, monga ma turbine a nthunzi ndi ma turbine a madzi. Prime mover imatchedwa turbine, ndipo makina ogwirira ntchito amatchedwa blade fluid machine.
Malinga ndi mfundo zosiyanasiyana zogwirira ntchito za fan, ikhoza kugawidwa m'magulu a tsamba ndi voliyumu, pakati pawo mtundu wa tsamba ukhoza kugawidwa m'magulu a axial flow, mtundu wa centrifugal ndi mixed flow. Malinga ndi kuthamanga kwa fan, ikhoza kugawidwa m'magulu a blower, compressor ndi ventilator. Muyezo wathu wamakono wamakampani amakina JB/T2977-92 umafotokoza izi: Fan ikutanthauza fan yomwe khomo lake ndi lolowera mpweya, lomwe kuthamanga kwake (gauge pressure) kuli kochepera 0.015MPa; Kuthamanga kwa outlet (gauge pressure) pakati pa 0.015MPa ndi 0.2MPa kumatchedwa blower; Kuthamanga kwa outlet (gauge pressure) koposa 0.2MPa kumatchedwa compressor.
Zigawo zazikulu za chophulitsira ndi: volute, collector ndi impeller.
Chosonkhanitsa mpweya chimatha kutsogolera mpweya ku impeller, ndipo momwe mpweya umalowera mu impeller zimatsimikiziridwa ndi mawonekedwe a chosonkhanitsacho. Pali mitundu yambiri ya mawonekedwe a chosonkhanitsa, makamaka: mbiya, kononi, kononi, kononi, kononi ya ...
Impeller nthawi zambiri imakhala ndi chivundikiro cha magudumu, gudumu, tsamba, ndi shaft disk, zomwe zimapangitsa kuti zikhale zovuta kwambiri, kapangidwe kake kamalumikizidwa kwambiri komanso molumikizidwa ndi riveted. Malinga ndi njira yotulutsira impeller ya ma angles osiyanasiyana oyika, imatha kugawidwa m'magulu atatu ozungulira, kutsogolo ndi kumbuyo. Impeller ndiye gawo lofunika kwambiri la fan ya centrifugal, loyendetsedwa ndi prime mover, ndi mtima wa centrifugal turinachinery, womwe umayang'anira njira yotumizira mphamvu yomwe yafotokozedwa ndi Euler equation. Kuyenda mkati mwa impeller ya centrifugal kumakhudzidwa ndi kuzungulira kwa impeller ndi kupindika kwa pamwamba ndipo kumatsatiridwa ndi deflow, return ndi zochitika zina za flow, kotero kuti kuyenda mu impeller kumakhala kovuta kwambiri. Mkhalidwe wa kuyenda mu impeller umakhudza mwachindunji magwiridwe antchito a aerodynamic ndi magwiridwe antchito a siteji yonse komanso ngakhale makina onse.
Volute imagwiritsidwa ntchito makamaka kusonkhanitsa mpweya wotuluka mu impeller. Nthawi yomweyo, mphamvu ya kinetic ya mpweya imatha kusinthidwa kukhala mphamvu yokhazikika ya mpweya mwa kuchepetsa liwiro la mpweya pang'ono, ndipo mpweyawo ukhoza kutsogozedwa kuti utuluke mu volute outlet. Monga makina a turbo amadzimadzi, ndi njira yothandiza kwambiri yowongolera magwiridwe antchito ndi magwiridwe antchito a blower pophunzira gawo lake lamkati. Kuti timvetse momwe kayendedwe ka madzi mkati mwa centrifugal blower ndikuwongolera kapangidwe ka impeller ndi volute kuti tiwongolere magwiridwe antchito ndi magwiridwe antchito, akatswiri achita kafukufuku wambiri woyambira wa chiphunzitso, kafukufuku woyesera komanso kuyerekezera manambala kwa centrifugal impeller ndi volute.
