Inonzi turbomachinery kuendesa simba kumvura inoyerera nguva dzose kuburikidza nekushanda kwemashizha paimpeller inotenderera kana kukurudzira kutenderera kwemashizha nesimba rinobva mumvura. Mu turbomachinery, mashizha anotenderera anoita basa rakanaka kana risina kunaka pamvura, zvichikwidza kana kuderedza kumanikidzwa kwayo. Turbomachinery yakakamurwa muzvikamu zviviri zvikuru: chimwe muchina unoshanda umo mvura inotora simba kuti iwedzere musoro wepressure kana musoro wemvura, zvakaita semapombi ane vane nemaventilator; Chimwe ndicho chinhu chinofambisa mvura, umo mvura inokura, inoderedza kumanikidzwa, kana kuti musoro wemvura unoburitsa simba, senge maturbine emvura nematurbine emvura. Chinhu chinofambisa mvura chinonzi turbine, uye muchina unoshanda unonzi muchina we blade fluid.
Zvichienderana nemisimboti yakasiyana yekushanda kwefeni, inogona kukamurwa kuita mhando yeblade nevolume, pakati payo mhando yeblade inogona kukamurwa kuita axial flow, centrifugal type uye mixed flow. Zvichienderana nekumanikidzwa kwefeni, inogona kukamurwa kuita blower, compressor uye ventilator. Standard yedu yemuchina wekugadzira magetsi JB/T2977-92 inoti: Fan inoreva fan ine door condition yekupinda nayo, ine exit pressure (gauge pressure) iri pasi pe 0.015MPa; Outlet pressure (gauge pressure) iri pakati pe 0.015MPa ne 0.2MPa inonzi blower; Outlet pressure (gauge pressure) iri pamusoro pe 0.2MPa inonzi compressor.
Zvikamu zvikuru zvemuchina wekuputira ndeizvi: volute, collector uye impeller.
Muunganidzi anogona kutungamira gasi kuenda kuimpeller, uye mamiriro ekuyerera kweimpeller anovimbiswa nejometri yemuunganidzi. Kune marudzi akawanda emaumbirwo emuunganidzi, kunyanya: barrel, cone, cone, arc, arc arc, arc cone nezvimwewo.
Impeller inowanzova negumbo revhiri, vhiri, banga, dhisiki remugodhi, zvikamu zvina, chimiro chayo chakanyanya kusungirirwa uye chakasungirirwa. Zvinoenderana nemhepo inobuda yeimpeller ine makona akasiyana ekuisa, inogona kukamurwa kuita matatu eradial, mberi uye kumashure. Impeller ndiyo chikamu chakakosha chefeni yecentrifugal, inotungamirwa nechinhu chikuru chinofambisa, ndiyo moyo we centrifugal turinachinery, ine basa rekufambisa simba rinotsanangurwa neEuler equation. Kuyerera mukati meimpeller yecentrifugal kunokanganiswa nekutenderera kweimpeller uye curvature yekumusoro uye inoperekedzwa ne deflow, return uye secondary flow phenomena, zvekuti kuyerera muimpeller kunove kwakaoma zvikuru. Mamiriro ekuyerera muimpeller anokanganisa zvakananga mashandiro e aerodynamic uye kushanda zvakanaka kwedanho rese uye kunyange muchina wese.
Volute inonyanya kushandiswa kuunganidza gasi rinobuda muimpeller. Panguva imwe chete, simba remagetsi regasi rinogona kushandurwa kuita simba rekumanikidza rakamira regasi nekuderedza kumhanya kwegasi zvine mwero, uye gasi rinogona kutungamirirwa kuti ribude muimpeller. Semuchina we fluid turbomachinery, inzira inoshanda kwazvo yekuvandudza mashandiro uye kushanda zvakanaka kwemuchina we blower nekudzidza munda wayo wemukati wekuyerera. Kuti tinzwisise mamiriro chaiwo ekuyerera mukati me centrifugal blower uye kuvandudza dhizaini ye impeller ne volute kuti tivandudze mashandiro uye kushanda zvakanaka, nyanzvi dzakaita ongororo yakawanda yedzidziso, tsvakiridzo yekuedza uye simulation yenhamba ye centrifugal impeller ne volute.
