E bitsoa turbomachinery ho fetisetsa matla ho phallo e tsoelang pele ea mokelikeli ka ketso e matla ea li-blades ho impeller e potolohang kapa ho khothalletsa ho potoloha ha li-blades ka matla a tsoang mokelikeli. Ho turbomachinery, mahare a potolohang a etsa mosebetsi o motle kapa o mobe holim'a mokelikeli, a phahamisa kapa a theola khatello ea ona. Turbomachinery e arotsoe ka mekhahlelo e 'meli e meholo: e' ngoe ke mochini o sebetsang oo mokelikeli o monyang matla ho eketsa hlooho ea khatello kapa hlooho ea metsi, joalo ka lipompo tsa vane le li-ventilator; E 'ngoe ke eona ntho e ka sehloohong e tsamaisang metsi, eo mokelikeli o ntseng o atoloha, o fokotsa khatello, kapa hlooho ea metsi e hlahisa matla, joalo ka li-turbine tsa mouoane le li-turbine tsa metsi. Mochine o ka sehloohong o bitsoa turbine, 'me mochine o sebetsang o bitsoa mochine oa blade fluid.
Ho ea ka melao-motheo e fapaneng ea ho sebetsa ea fan, e ka aroloa ka mofuta oa lehare le mofuta oa molumo, oo mofuta oa lehare o ka aroloa ka phallo ea axial, mofuta oa centrifugal le phallo e tsoakiloeng. Ho ea ka khatello ea fan, e ka aroloa ka blower, compressor le ventilator. Tekanyetso ea rona ea hajoale ea indasteri ea mochini JB/T2977-92 e re: Fene e bua ka fene eo monyako oa eona e leng boemo bo tloaelehileng ba monyako, eo khatello ea eona ea ho tsoa (khatello ea gauge) e leng ka tlase ho 0.015MPa; Khatello ea ho tsoa (khatello ea gauge) pakeng tsa 0.015MPa le 0.2MPa e bitsoa blower; Khatello ea ho tsoa (khatello ea gauge) e kholo ho feta 0.2MPa e bitsoa compressor.
Likarolo tse ka sehloohong tsa blower ke: volute, pokello le impeller.
'Mokelli a ka lebisa khase ho impeller,' me boemo ba phallo ea inlet ea impeller bo tiisitsoe ke geometry ea mokelli. Ho na le mefuta e mengata ea libopeho tse bokellang, haholo-holo: barrel, cone, cone, arc, arc arc, arc cone joalo-joalo.
Impeller ka kakaretso e na le sekoaelo sa mabili, lebili, lehare, shaft disk likarolo tse 'ne, sebopeho sa eona se hokahane haholo le sehokelo sa marang-rang. Ho ea ka impeller outlet ea li-angles tse fapaneng tsa ho kenya, li ka aroloa ka radial, pele le ka morao tse tharo. The impeller ke karolo ea bohlokoa ka ho fetisisa ea fan ea centrifugal, e tsamaisoang ke moetapele ea ka sehloohong, ke pelo ea centrifugal turinachinery, e ikarabellang bakeng sa mokhoa oa ho fetisa matla o hlalositsoeng ke Euler equation. Ho phalla ka hare ho centrifugal impeller ho angoa ke ho pota-pota le ho pota-pota ka holim'a metsi 'me ho tsamaisana le ho fokotseha, ho khutla le liketsahalo tsa bobeli tsa phallo, e le hore ho phalla ho impeller ho be thata haholo. Boemo ba ho phalla ho impeller bo ama ka ho toba ts'ebetso ea aerodynamic le katleho ea sethala sohle esita le mochine oohle.
Volute e sebelisoa haholo ho bokella khase e tsoang ho impeller. Ka nako e ts'oanang, matla a kinetic a khase a ka fetoloa matla a static khatello ea khase ka ho fokotsa lebelo la khase ka mokhoa o itekanetseng, 'me khase e ka tataisoa hore e tlohe sebakeng sa volute. Joalo ka mochini oa turbomachine, ke mokhoa o sebetsang haholo oa ho ntlafatsa ts'ebetso le ts'ebetso e sebetsang ea blower ka ho ithuta sebaka sa eona sa phallo ea kahare. E le ho utloisisa boemo ba 'nete ba phallo ka hare ho centrifugal blower le ho ntlafatsa moralo oa impeller le boithaopo ho ntlafatsa ts'ebetso le katleho, litsebi li entse tlhahlobo e ngata ea theory, lipatlisiso tsa liteko le papiso ea lipalo ea centrifugal impeller le volute.
