Ibizwa ngokuthi i-turbomachinery ukudlulisela amandla ekugelezeni okuqhubekayo koketshezi ngesenzo esishintshashintshayo sama-blades ku-impeller ejikelezayo noma ukukhuthaza ukujikeleza kwama-blades ngamandla avela kuketshezi. Ku-turbomachinery, ama-blades ajikelezayo enza umsebenzi omuhle noma omubi kuketshezi, ephakamisa noma ehlisa ingcindezi yalo. I-Turbomachinery ihlukaniswe ngezigaba ezimbili eziyinhloko: eyodwa umshini osebenzayo lapho uketshezi lumunca khona amandla ukuze kwandiswe ikhanda lokucindezela noma ikhanda lamanzi, njengephampu ye-vane kanye nama-ventilator; Enye i-prime mover, lapho uketshezi lukhula khona, lunciphisa ingcindezi, noma ikhanda lamanzi likhiqiza amandla, njenge-steam turbines kanye nama-water turbines. I-prime mover ibizwa ngokuthi i-turbine, kanti umshini osebenzayo ubizwa ngokuthi umshini we-blade fluid.
Ngokwezimiso zokusebenza ezahlukene zefeni, ingahlukaniswa ngohlobo lwe-blade kanye nohlobo lwevolumu, phakathi kwazo uhlobo lwe-blade lungahlukaniswa ngokugeleza kwe-axial, uhlobo lwe-centrifugal kanye nokugeleza okuxubile. Ngokwengcindezi yefeni, ingahlukaniswa ngokufutha, i-compressor kanye ne-ventilator. Izinga lethu lamanje lemboni yemishini i-JB/T2977-92 libeka: Ifeni ibhekisela kufeni okungena kwayo kuyisimo sokungena komoya esijwayelekile, okucindezela kwayo ukuphuma (ingcindezi yokulinganisa) kungaphansi kuka-0.015MPa; Ingcindezi yokukhipha (ingcindezi yokulinganisa) phakathi kuka-0.015MPa no-0.2MPa ibizwa ngokuthi i-blower; Ingcindezi yokukhipha (ingcindezi yokulinganisa) enkulu kune-0.2MPa ibizwa ngokuthi i-compressor.
Izingxenye eziyinhloko zomshini wokufutha yilezi: i-volute, i-collector kanye ne-impeller.
Umqoqi angaqondisa igesi kuyi-impeller, futhi isimo sokugeleza kokungena kwe-impeller siqinisekiswa yi-geometry yomqoqi. Kunezinhlobo eziningi zezimo zomqoqi, ikakhulukazi: i-barrel, i-cone, i-cone, i-arc, i-arc arc, i-arc cone njalo njalo.
I-Impeller ngokuvamile inesembozo samasondo, isondo, i-blade, i-shaft disk izingxenye ezine, isakhiwo sayo sixhunyaniswe kakhulu futhi sinama-riveted. Ngokusho kwe-impeller outlet yama-engeli ahlukene okufakwa, ingahlukaniswa ibe yi-radial, phambili nangemuva ezintathu. I-impeller iyingxenye ebaluleke kakhulu yefeni ye-centrifugal, eqhutshwa yi-prime mover, iyinhliziyo ye-centrifugal turinachinery, ephethe inqubo yokudlulisa amandla echazwe yi-Euler equation. Ukugeleza ngaphakathi kwe-impeller ye-centrifugal kuthintwa ukujikeleza kwe-impeller kanye nokugoba kobuso futhi kuhambisane nokuphuma, ukubuya kanye nezenzakalo zokugeleza kwesibili, ukuze ukugeleza kwe-impeller kube yinkimbinkimbi kakhulu. Isimo sokugeleza ku-impeller sithinta ngqo ukusebenza kwe-aerodynamic kanye nokusebenza kahle kwesigaba sonke ngisho nomshini wonke.
I-volute isetshenziswa kakhulu ukuqoqa igesi ephuma ku-impeller. Ngesikhathi esifanayo, amandla e-kinetic egesi angaguqulwa abe amandla okucindezela anganyakazi egesi ngokunciphisa isivinini segesi ngokulinganisela, futhi igesi ingaqondiswa ukuthi iphume endaweni yokukhipha i-volute. Njenge-fluid turbomachinery, iyindlela ephumelela kakhulu yokuthuthukisa ukusebenza kahle nokusebenza kahle kwe-blower ngokutadisha insimu yayo yokugeleza kwangaphakathi. Ukuze siqonde isimo sangempela sokugeleza ngaphakathi kwe-centrifugal blower futhi sithuthukise ukwakheka kwe-impeller ne-volute ukuze sithuthukise ukusebenza kahle, izazi zenze ukuhlaziywa okuningi okuyisisekelo kwethiyori, ucwaningo lokuhlola kanye nokulingisa ngezinombolo kwe-centrifugal impeller ne-volute.
