Kubizwa ngokuthi i-turbomachinery ukudlulisa amandla ekugelezeni okuqhubekayo koketshezi ngesenzo esiguqukayo sama-blade ku-impeller ejikelezayo noma ukukhuthaza ukujikeleza kwama-blades ngamandla avela oketshezini. Emishinini ye-turbomachine, ama-blade ajikelezayo enza umsebenzi omuhle noma omubi oketshezini, enyusa noma ehlisa ingcindezi yawo. I-Turbomachinery ihlukaniswe yaba izigaba ezimbili eziyinhloko: eyodwa umshini osebenzayo lapho uketshezi luthatha khona amandla okwandisa ikhanda lokucindezela noma ikhanda lamanzi, njengamaphampu ane-vane nama-ventilators; Okunye ukunyakaza okuyinhloko, lapho uketshezi lukhula, kunciphisa ukucindezela, noma ikhanda lamanzi likhiqiza amandla, njengezinjini zesitimu nezinjini zamanzi. I-prime mover ibizwa nge-turbine, kanti umshini osebenzayo ubizwa ngokuthi umshini we-blade fluid.
Ngokwemigomo yokusebenza ehlukene ye-fan, ingahlukaniswa ngohlobo lwe-blade nohlobo lwevolumu, phakathi kwayo uhlobo lwe-blade lungahlukaniswa lube ukugeleza kwe-axial, uhlobo lwe-centrifugal nokugeleza okuxubile. Ngokwengcindezi ye-fan, ingahlukaniswa i-blower, i-compressor ne-ventilator. Izinga lethu lamanje lemboni yemishini i-JB/T2977-92 liyacacisa: Ifeni ibhekisela kufeni leyo yokungena yayo iyisimo sokungena somoya esivamile, umfutho wayo wokuphuma (umfutho wegeji) ungaphansi kuka-0.015MPa; Ingcindezi yokuphuma (gauge pressure) phakathi kuka-0.015MPa no-0.2MPa ibizwa ngokuthi i-blower; Ingcindezi yokuphuma (gauge pressure) engaphezu kuka-0.2MPa ibizwa ngokuthi i-compressor.
Izingxenye eziyinhloko ze-blower ziyi: volute, collector kanye ne-impeller.
Umqoqi angakwazi ukuqondisa igesi ku-impeller, futhi isimo sokugeleza kwe-inlet se-impeller siqinisekiswa yi-geometry yomqoqi. Kunezinhlobo eziningi zomumo womqoqi, ikakhulukazi: umgqomo, ikhoni, ikhoni, i-arc, i-arc arc, i-arc cone nokunye.
I-Impeller ngokuvamile inesembozo samasondo, isondo, i-blade, i-shaft disk izingxenye ezine, isakhiwo sayo sixhunywe kakhulu futhi i-riveted. Ngokusho kwe-impeller yokuphuma kwama-engeli ahlukene wokufaka, angahlukaniswa abe yi-radial, phambili nangemuva kathathu. I-impeller iyingxenye ebaluleke kakhulu ye-centrifugal fan, eqhutshwa yi-prime mover, iyinhliziyo ye-centrifugal turinachinery, ebhekene nenqubo yokudlulisa amandla echazwe yi-Euler equation. Ukugeleza ngaphakathi kwe-impeller ye-centrifugal kuthinteka ukujikeleza kwe-impeller kanye ne-surface curvature futhi kuhambisane ne-deflow, ukubuyisela kanye nokugeleza kwe-secondary phenomena, ukuze ukugeleza ku-impeller kube nzima kakhulu. Isimo sokugeleza ku-impeller sithinta ngokuqondile ukusebenza kwe-aerodynamic nokusebenza kahle kwesiteji sonke ngisho nomshini wonke.
I-volute isetshenziswa kakhulu ukuqoqa igesi ephuma ku-impeller. Ngesikhathi esifanayo, amandla e-kinetic wegesi angaguqulwa abe amandla okucindezela okumile kwegesi ngokunciphisa ngokusesilinganisweni isivinini segesi, futhi igesi ingaqondiswa ukushiya i-volute outlet. Njengomshini we-fluid turbomachinery, iyindlela ephumelela kakhulu yokuthuthukisa ukusebenza nokusebenza kahle kwe-blower ngokufunda inkambu yayo yokugeleza yangaphakathi. Ukuze uqonde isimo sokugeleza kwangempela ngaphakathi kwesivutheli se-centrifugal futhi kuthuthukiswe ukwakheka kwe-impeller kanye nevolute ukuze kuthuthukiswe ukusebenza nokusebenza kahle, osolwazi benze ukuhlaziya okuningi okuyisisekelo kwethiyori, ucwaningo lokuhlola kanye nokulingisa izinombolo kwe-centrifugal impeller kanye nevolute.
