Kubizwa ngokuba yi-turbomachinery ukuhambisa amandla ekuhambeni okuqhubekayo kolwelo ngentshukumo eguquguqukayo yeencakuba kwi-impeller ejikelezayo okanye ukukhuthaza ukujikeleza kweeblades ngamandla asuka kulwelo.Kwi-turbomachinery, iiblade ezijikelezayo zenza umsebenzi olungileyo okanye ongalunganga kulwelo, ukunyusa okanye ukwehlisa uxinzelelo lwawo.I-Turbomachinery yahlulwe yangamacandelo amabini aphambili: enye ngumatshini osebenzayo apho ulwelo luthatha amandla okunyusa intloko yoxinzelelo okanye intloko yamanzi, njengeempompo ze-vane kunye ne-ventilators;Enye yi-prime mover, apho ulwelo luyanda, lunciphisa uxinzelelo, okanye intloko yamanzi ivelisa amandla, anjengeeinjini zomphunga neeinjini zamanzi.Umatshini ohamba phambili ubizwa ngokuba yiinjini yomoya, kwaye umatshini osebenzayo ubizwa ngokuba ngumatshini we-blade fluid.
Ngokwemigaqo yokusebenza eyahlukeneyo ye-fan, inokwahlulwa ibe yintlobo ye-blade kunye nodidi lwevolumu, phakathi kwayo uhlobo lwe-blade lunokwahlulwa lube yi-axial flow, uhlobo lwe-centrifugal kunye nokuhamba okuxubileyo.Ngokoxinzelelo lwe-fan, inokwahlulwa ibe yi-blower, i-compressor kunye ne-ventilator.Umgangatho wethu wangoku woshishino loomatshini i-JB/T2977-92 ichaza: Ifeni ibhekisa kwifeni ekungenwa kwayo yimeko yokungena yomoya, oxinzelelo lokuphuma (uxinzelelo lwegeyiji) lungaphantsi kwe-0.015MPa;Uxinzelelo lokuphuma (uxinzelelo lwegeyiji) phakathi kwe-0.015MPa kunye ne-0.2MPa ibizwa ngokuba yi-blower;Uxinzelelo lwe-outlet (uxinzelelo lwe-gauge) olukhulu kune-0.2MPa lubizwa ngokuba yi-compressor.
Iinxalenye eziphambili ze-blower zezi: i-volute, umqokeleli kunye ne-impeller.
Umqokeleli unokuqondisa igesi kwi-impeller, kwaye imeko yokungena kwe-inlet ye-impeller iqinisekiswa yijometri yomqokeleli.Kukho iintlobo ezininzi zeemilo zomqokeleli, ikakhulu: umgqomo, ikhowuni, ikhowuni, iarc, iarc, iarc cone njalo njalo.
I-Impeller ngokubanzi inekhava yevili, ivili, iblade, i-shaft disk amacandelo amane, isakhiwo sayo sidityanisiwe kwaye sidityanisiwe.Ngokutsho kwe-impeller yokuphuma kwee-engile zokufakela ezahlukeneyo, zinokwahlulwa zibe yi-radial, phambili nasemva ezintathu.I-impeller iyona nto ibaluleke kakhulu kwi-fan ye-centrifugal, eqhutywe yi-prime mover, yintliziyo ye-turinachinery ye-centrifugal, ejongene nenkqubo yokuhambisa amandla echazwe yi-Euler equation.Ukuhamba ngaphakathi kwe-centrifugal impeller kuchaphazeleka ngokujikeleza kwe-impeller kunye ne-surface curvature kunye nokuhamba kunye ne-deflow, ukubuyisela kunye ne-second flow phenomena, ukwenzela ukuba ukuhamba kwi-impeller kube nzima kakhulu.Isimo sokuhamba kwi-impeller sichaphazela ngokuthe ngqo ukusebenza kwe-aerodynamic kunye nokusebenza kakuhle kwenqanaba lonke kunye nomatshini wonke.
I-volute isetyenziselwa ukuqokelela igesi ephuma kwi-impeller.Ngexesha elifanayo, amandla e-kinetic yegesi anokuguqulwa abe yi-static yamandla yoxinzelelo lwegesi ngokunciphisa ngokulinganisela isantya segesi, kwaye igesi inokukhokelwa ukuba ishiye i-volute outlet.Njengomatshini we-turbomachine olwelo, yindlela esebenzayo kakhulu yokuphucula ukusebenza kunye nokusebenza kakuhle kwe-blower ngokufunda indawo yayo yangaphakathi yokuhamba.Ukuze uqonde imeko yokwenyani yokuqukuqela ngaphakathi kwesivuthelo se-centrifugal kunye nokuphucula uyilo lwe-impeller kunye nevolonti yokuphucula ukusebenza kunye nokusebenza kakuhle, abaphengululi baye benza uhlalutyo oluninzi olusisiseko lwethiyori, uphando lovavanyo kunye nokulinganisa kwamanani kwe-centrifugal impeller kunye nevolute.
