Ts'ebetso ea fan ea tubular axial e angoa ke ho hlaka ha radial
Mocheso oa khase o tsamaisoang ke fan ea tubular axial flow ke khase e phatlohang le e tukang e kang carbon monoxide, petroleum gas, lik'hemik'hale kapa khase ea I e nang le phofo e kotsi. Haeba karolo ea rotor ea mofuta ona oa fan e entsoe ka tšepe e akaretsang ea khabone, ho bonolo ho hlaba hammoho le ho lebisa mollong oa khase ka lebaka la ho thulana pakeng tsa likarolo, kapa litšila tse kang lehlabathe kapa lerōle la tšepe li kenngoa ka har'a rotor, e leng se etsang hore kotsing e mpe. E le ho qoba kotsi ea mofuta ona, ha fan e fana ka mochine oa khase o nang le boemo bo tlaase ba ho phatloha, mocheso oa fan o entsoe ka tšepe ea tšepe, 'me impeller e entsoe ka aluminium. Empa ha fene e fetisang boemo bo phahameng ba khase e sebelisoang e entsoe ka thepa ea aluminium.
Ho hlaka ha mahlaseli a tubular axial fan ho bolela ho hlaka pakeng tsa lehare le lerako le ka hare la casing, 'me ho hlaka ha axial ho bolela ho hlaka pakeng tsa "impeller cascade". Boholo ba mefuta e 'meli ea tumello bo na le tšusumetso ts'ebetsong ea fan.
Phallo ea mahlaseli a tubular axial flow fan e kholo haholo, 'me khatello e mpe e phahame, e leng eona e tlamang ho baka phapang e kholo ea khatello pakeng tsa lehare le mahlakoreng a mabeli a ho tlosoa ha casing. Phapang ea khatello ke lebaka le ka sehloohong la ho lutla ha moea oa axial. Ho lutla ho khutlisetsoa morao ka lehare ebe ho lahleloa sepakapakeng, ho etsa "phallo ea moea e potolohang. Mosebetsi oa karolo ena ea phallo ea moea o senyeha, e le hore katleho ea fan e fokotsehe.
Rotor e bolella ho potoloha, hammoho le khase ea axial spiral pele, hobane moea ka boeona o na le boima ba 'mele le mongobo le likaroloana tsa lerōle tse teng moeeng, li bolelloa hore li bilikise lehare ho pota-pota, likaroloana tsa moea li teteaneng haufi le casing, haufi le ka hare. lebota la phallo ea spiral e eang pele, haufi le tataiso ea radial ho eketsa sekhahla sa phallo ea moea le khatello e mpe. Tabeng ena, "radial clearance" e kholo haholo 'me e khutlela lebantang la "clearance" ho potoloha casing ho hlahisa palo e kholo ea moea oa tubular o phallang ka lehlakoreng la axial ka morao, e amang phallo e tloaelehileng ea moea, e le hore moea o sebelise mosebetsi. ka lefeela, ka hona ho fokotsa ts'ebetso.
Ha ho etsoa le ho fetola lihlahisoa, hoa hlokahala ho boloka sebaka se itseng sa axial pakeng tsa cascades, haholo-holo ho netefatsa hore li-cascade tse latelang li na le moea o tšoanang le ho felisa tšusumetso pakeng tsa e mong le e mong, ho seng joalo maemo a sebetsang a tla senyeha. Phallo e sa lekaneng ea moea e ka sebetsa joalo ka mohloli oa ho thothomela, e leng ho etsang hore lehare le ka morao le thothomele. Ho fapana le hoo, tumello ea axial e kholo haholo, e tla etsa hore boholo ba axial bo be telele haholo. Ka hona, boholo ba tumello ea axial bo na le tšusumetso ho lerata, ho thothomela le boholo ba axial ea fan.
Ka holimo ke Xiaobian hore u tlise litaba tsohle tsa tsebo, ke tšepa ho u thusa, hape ke u amohela hore u tsoele pele ho ela hloko sebaka sena, Xiaobian o tla u tlisetsa tlhahisoleseding e eketsehileng ea tsebo ea sehlahisoa bakeng sa boitsebiso ba hau.
