Utyalo-mali kwi-fan yekhwalithi ephezulu ayiphuculi kuphela umgangatho womoya kodwa iqinisekisa ukusebenza okuthembekileyo kuzo zonke izicelo ezahlukeneyo, okwenza kube yinto ebalulekileyo yokongeza kuyo nayiphi na inkqubo yokukhupha umoya.

FAQ

Yintoni injongo yefeni yokukhupha i-centrifugal eluphahleni?

Uphahla lwe-centrifugal exhaust fan lususa ungcoliseko lomoya wangaphakathi, ubushushu kunye nokufuma. Iqinisekisa ukungena komoya okufanelekileyo kwiindawo zokuhlala, zorhwebo, kunye nezoshishino. Olu hlobo lwefeni luphucula umgangatho womoya kwaye lugcina indawo epholileyo yangaphakathi.

Ifeni yokukhupha i-centrifugal eluphahleni yohluke njani kwezinye iintlobo zeefeni?

Abalandeli be-centrifugal exhaust eluphahleni basebenzisa amandla aphakathi ukukhupha umoya ngokufanelekileyo. Iincakuba ezigotywe ngasemva ze-impeller ziphucula ukusebenza kwe-aerodynamic. Aba balandeli baphatha izicelo zoxinzelelo oluphezulu lwe-static bhetele kunabalandeli be-axial, bebenza bafanelekele iimeko ezibango.

Zeziphi izinto ezigqiba ubungakanani befeni efunekayo?

Ubungakanani befeni buxhomekeke kwiimfuno zomoya zesakhiwo. Imiba ephambili ibandakanya uluhlu lomthamo womoya (ulinganiswa nge-m³/h) kunye namanqanaba oxinzelelo olumileyo. Iimitha ze-impeller ezinkulu, ezinje nge-300 mm ukuya kwi-2000 mm, zivumela iimfuno zokuhamba komoya eziphezulu kumashishini okanye kwiisetingi zorhwebo.

Ngaba aba balandeli bangasebenza kwiimeko zemozulu ezimandundu?

Ewe, iifeni ze-centrifugal exhaust eluphahleni ziyilwe ngezinto ezikwaziyo ukumelana nemozulu njengentsimbi yegalvanized okanye ialuminiyam. Iimpawu ezifana nezindlu ezivaliweyo zeemoto kunye ne-grilles ezikhuselayo ziqinisekisa ukuqina kwiimeko ezinzima, kubandakanywa imvula enkulu, imimoya enamandla, kunye namaqondo okushisa aphezulu.

Zeziphi izinto ozikhethelayo eziphucula ukusebenza kwefeni?

Izinto ezikhethwayo ziquka i-inlet dampers, ii-nozzles zokucoca i-impeller, kunye ne-vibration sensors. Izidambisi manzi ezingenayo zilawula ukuhamba komoya, ngelixa ukucoca imilomo lwenza lula ukugcinwa ngokususa inkunkuma. Izinzwa zeVibration zibona imiba yoomatshini kwangoko, ziqinisekisa ukusebenza kakuhle kunye nokuthembeka.

Ngaba aba balandeli bawonga amandla?

Uninzi lweefeni eziphuma eluphahleni lwe-centrifugal zibandakanya uyilo oluwonga amandla. Ukulawulwa kwesantya esiguquguqukayo kuvumela abasebenzisi ukuba bahlengahlengise ukuhamba komoya ngokusekwe kwimfuno, ukunciphisa ukusetyenziswa kwamandla. Ii-impellers ezigotywe ngasemva kunye neenkqubo zothumelo ezihambele phambili zokwandisa ukusebenza kakuhle.

Ingaba amazinga engxolo ayichaphazela njani ukhetho lwabalandeli?

Amanqanaba engxolo aphembelela intuthuzelo kwiindawo zokuhlala kunye nezorhwebo. Iifeni ezinee-impellers ezigotshwe ngasemva kunye nezinto ezidambisa ivibration zisebenza ngokuzolileyo. Ukukhetha iimodeli ezinomlinganiselo ophantsi we-decibel kuqinisekisa ukuphazamiseka okuncinci kwaye kwandisa ukwaneliseka kwabahlali.

Loluphi ugcino olufunekayo kwaba balandeli?

Ukugcinwa kwesiqhelo kubandakanya ukuhlola i-shaft engundoqo, ibhokisi yokuthwala, kunye neebheringi eziqengqelekayo. Ukucoca i-impeller nge-nozzle kususa uthuli kunye ne-debris. Ukubeka iliso kwiqondo lokushisa kunye nezinzwa zokungcangcazela kunceda ukuchonga imiba enokubakho kwangoko, ukuqinisekisa ukusebenza kwexesha elide.

Ngaba aba balandeli banokudibana nomsebenzi okhoyo?

Ewe, iifeni eziphuma eluphahleni ze-centrifugal zinokudityaniswa nombhobho okhoyo. Amalungu aguquguqukayo kunye nemithombo yohlobo oludibeneyo oludambisayo lwenza lula ulungelelwaniso. Ukutshatisa iimetriki zokusebenza zefeni, ezifana neCFM kunye noxinzelelo lwe-static, kunye nomthamo we-ductwork iqinisekisa ukuhambelana.

Zeziphi iziqinisekiso ekufuneka abathengi bazijonge?

Abathengi kufuneka babeke phambili abalandeli abaqinisekisiweyo yimibutho efana ne-AMCA okanye i-UL. Ezi ziqinisekiso ziqinisekisa ukuthotyelwa kwemigangatho yokusebenza, ukhuseleko, kunye nokusebenza kakuhle. Abalandeli abaqinisekisiweyo babonelela ngokusebenza okuthembekileyo kwaye bahlangabezana neemfuno zolawulo lwezicelo ezahlukeneyo.
