Inonzi turbomachinery kuendesa simba kune kuenderera kuyerera kwemvura nekuita kwekuchinja kwemablades pane inotenderera inotenderera kana kusimudzira kutenderera kwemablades nesimba kubva mumvura. Mu turbomachinery, mashizha anotenderera anoita basa rakanaka kana rakashata pamvura, kusimudza kana kuderedza kumanikidza kwayo. Turbomachinery yakakamurwa kuita zvikamu zviviri zvikuru: imwe ndiyo muchina unoshanda kubva kune iyo fluid inotora simba kuti iwedzere kudzvanywa musoro kana musoro wemvura, senge vane pombi uye ventilators; Imwe yacho ndiyo yekutanga mover, umo mvura inowedzera, inoderedza kudzvanywa, kana musoro wemvura unoburitsa simba, senge turbines nemagetsi emvura. Iyo yekutanga mover inonzi turbine, uye muchina unoshanda unonzi blade fluid muchina.
Zvinoenderana neakasiyana misimboti yekushanda ye fan, inogona kukamurwa kuita blade mhando uye vhoriyamu mhando, pakati peiyo blade mhando inogona kukamurwa kuita axial kuyerera, centrifugal mhando uye yakasanganiswa kuyerera. Zvinoenderana nekumanikidza kwe fan, inogona kukamurwa kuita blower, compressor uye ventilator. Yedu yazvino mechanic industry standard JB/T2977-92 inotaridza: Iyo feni inoreva fan iyo yekupinda ndiyo yakajairwa mhepo yekupinda mamiriro, ayo ekubuda kwawo (gauge pressure) iri pasi pe0.015MPa; The outlet pressure (gauge pressure) pakati pe0.015MPa ne0.2MPa inonzi blower; The outlet pressure (gauge pressure) yakakura kudarika 0.2MPa inonzi compressor.
Zvikamu zvikuru zve blower ndezvi: volute, muunganidzi uye impeller.
Muunganidzi anogona kutungamira gasi kune impeller, uye iyo inlet kuyerera mamiriro eiyo impeller inovimbiswa neiyo geometry yemuunganidzi. Kune akawanda marudzi ezvimiro zvevaunganidzi, kunyanya: mbiya, koni, koni, arc, arc arc, arc cone zvichingodaro.
Impeller kazhinji ine vhiri chivharo, vhiri, blade, shaft disk zvinhu zvina, chimiro chayo chinonyanya kusungirirwa uye riveted yekubatanidza. Zvinoenderana neiyo impeller yekubuda kwemakona akasiyana ekuisa, anogona kukamurwa kuita radial, kumberi uye kumashure matatu. Iyo impeller ndiyo inonyanya kukosha ye centrifugal fan, inotungamirirwa ne prime mover, ndiyo mwoyo we centrifugal turinachinery, inotarisira nzira yekufambisa simba inotsanangurwa neEuler equation. Iyo inoyerera mukati meiyo centrifugal impeller inobatwa neiyo impeller kutenderera uye pamusoro curvature uye inoperekedzwa nedeflow, kudzoka uye yechipiri kuyerera kwezviitiko, kuitira kuti kuyerera kweiyo impeller kuve kwakaoma kwazvo. Mamiriro ekuyerera mune impeller anokanganisa zvakananga kuita kweaerodynamic uye kugona kwechikamu chose uye kunyangwe muchina wese.
Iyo volute inonyanya kushandiswa kuunganidza gasi rinobuda mu impeller. Panguva imwecheteyo, kinetic simba regesi rinogona kushandurwa kuita static pressure simba regasi nekudzikisa zvine mwero kumhanya kwegasi, uye gasi rinogona kutungamirwa kusiya volute kubuda. Seye fluid turbomachinery, inzira inoshanda kwazvo yekuvandudza mashandiro uye kushanda zvakanaka kwe blower nekudzidza yayo yemukati kuyerera ndima. Kuti tinzwisise mamiriro chaiwo ekuyerera mukati me centrifugal blower uye kugadzirisa dhizaini ye impeller uye kuvhota kuvandudza mashandiro uye kugona, nyanzvi dzakaita zvakawanda zvekutanga ongororo yekuongorora, yekuyedza tsvakiridzo uye manhamba simulation ye centrifugal impeller uye volute.
