Amadayamitha ama-impeller amakhudlwana, afana no-300 mm kuya ku-2000 mm, avumela izidingo zokugeleza komoya okuphezulu ezilungiselelweni zezimboni noma ezentengiso.

Ingabe laba balandeli bangakwazi ukusebenza ezimweni zezulu ezimbi kakhulu?

Yebo, amafeni e-exhaust ophahleni adizayinelwe ngezinto ezimelana nesimo sezulu njengensimbi eyi-galvanized noma i-aluminium. Izici ezifana nezindlu ezivaliwe zezimoto kanye nama-grille okuvikela ziqinisekisa ukuqina ezimweni ezinzima, okuhlanganisa imvula enamandla, umoya onamandla, namazinga okushisa aphezulu.

Yiziphi izici ozikhethela zona ezithuthukisa ukusebenza kwefeni?

Izici ongazikhethela zihlanganisa ama-inlet dampers, ama-nozzle okuhlanza ama-impeller, nezinzwa zokudlidliza. Ama-dampers angenisa umoya alawula ukugeleza komoya, kuyilapho ukuhlanza imibhobho kwenza ukulungiswa kube lula ngokususa udoti. Izinzwa zokudlidliza zibona izinkinga zomshini kusenesikhathi, ziqinisekisa ukusebenza kahle nokwethembeka.

Ingabe laba balandeli bayonga amandla?

Amafeni amaningi ophahleni we-centrifugal exhaust ahlanganisa imiklamo eyonga amandla. Ukulawulwa kwesivinini esiguquguqukayo kuvumela abasebenzisi ukuthi balungise ukugeleza komoya ngokuya ngesidingo, behlise ukusetshenziswa kwamandla. Ama-impeller agokele emuva kanye nezinhlelo zokudlulisa ezithuthukile zithuthukisa ukusebenza kahle.

Amazinga omsindo akuthinta kanjani ukukhetha kwabalandeli?

Amazinga omsindo athonya ukunethezeka kwezindawo zokuhlala nezohwebo. Abalandeli abanama-impeller ajikele emuva kanye nezinto ezidambisa ukudlidliza basebenza ngokuthula. Ukukhetha amamodeli anezilinganiso eziphansi ze-decibel kuqinisekisa ukuphazamiseka okuncane futhi kuthuthukisa ukwaneliseka kwabahlali.

Iyiphi isondlo edingekayo kulaba balandeli?

Ukunakekelwa okujwayelekile kuhlanganisa ukuhlola i-shaft eyinhloko, i-bearing box, nama-rolling bearings. Ukuhlanza i-impeller nge-nozzle kususa uthuli nemfucumfucu. Ukwengamela izinzwa zezinga lokushisa elithwalayo nezidlidlizayo kusiza ukukhomba izinkinga ezingaba khona kusenesikhathi, kuqinisekiswe ukusebenza kwesikhathi eside.

Ingabe laba balandeli bangahlanganisa nama-ductwork akhona?

Yebo, amafeni e-exhaust ophahleni lwe-centrifugal angahlanganisa ne-ductwork ekhona. Amalunga aguquguqukayo kanye neziphethu ezincibilikayo zohlobo oluhlanganisiwe kwenza ukuqondana kube lula. Ukufanisa amamethrikhi okusebenza kwabalandeli, njenge-CFM nengcindezi emile, nomthamo we-ductwork kuqinisekisa ukuhambisana.

Yiziphi izitifiketi okufanele abathengi bazibheke?

Abathengi kufanele babeke phambili abalandeli abagunyazwe izinhlangano ezifana ne-AMCA noma i-UL. Lezi zitifiketi ziqinisekisa ukuthobelana namazinga okusebenza, ukuphepha, nokusebenza kahle. Abalandeli abaqinisekisiwe bahlinzeka ngokusebenza okuthembekile futhi bahlangabezana nezimfuneko zokulawula zezinhlelo zokusebenza ezihlukahlukene.
