Iimpawu zokuSebenza kwabalandeli babalandeli be-Centrifugal

Ngaba ukhe wayibona ifeni enkulu engqukuva kwisilingi yeklasi yakho? Le fan ijikeleza umoya ikunceda ukuba uzive upholile kwaye ukhululekile. Oku kwaziwa njengefeni ye-centrifugal, kwaye le yindlela ehambisa ngayo umoya kwigumbi. Kwaye ukujonga nzulu ngakumbi ekusebenzeni kwabalandeli be-centrifugal kwaye kutheni kubalulekile. 

Basebenza njani abalandeli beCentrifugal? 

Igama elinye elibalulekileyo kukusebenza kakuhle, okanye indlela esebenza kakuhle ngayo into ethile. Kwiifeni ze-centrifugal, ukusebenza kakuhle ngumlinganiselo wobungakanani bomoya oshukunyiswa yifeni kunye nobungakanani bamandla afunekayo ukwenza oko. Ifeni esebenza ngakumbi ihambisa umoya omninzi ngexabiso elincinci lenkcitho yamandla. Yinto entle le kuba yonga umbane kwaye igcina iindleko ziphantsi. 

Abalandeli abahlukeneyo banemisebenzi eyahlukeneyo yokwenza. Ngokomzekelo, ezinye zisetyenziselwa ukupholisa igumbi ngemini eshushu, ngoxa abanye abalandeli bencedisa ekukhupheni umsi okanye ivumba elibi. Uhlobo lwefeni oya kuyidinga luya kuxhomekeka kwinjongo yayo. Inyathelo lokuqala ekukhetheni ifeni elungileyo kukwazi ukuba uyifunela ntoni. 

Ukuhamba komoya kunye noxinzelelo-Ithetha ntoni kwiiFani zeCentrifugal 

Iifeni ezinqumlayo luhlobo lwefeni ehambisa umoya ngesixhobo sokuvuthela. Umoya ungena ngee-fan blades (ezaziwa ngokuba zii-impellers), uhamba ngazo kwaye ugxothelwe kwigumbi. Ukuhamba komoya okutyhalelwe ngaphandle yi-fan kukuhamba komoya, kulinganiswa ngee-cubic feet ngomzuzu (CFM). Oku kusixelela ubungakanani bomoya onokuthi ifeni ihambe ngexesha elithile. 

Ifeni ibangela uxinzelelo kwigumbi njengoko ityhala umoya. Kwaye uxinzelelo lulo olutyhala umoya ukusuka kwelinye igumbi ukuya kwelinye. Okukhona uxinzelelo olukhulu, kokukhona umoya uya kuhamba ngokukhawuleza. Uxinzelelo oluveliswa yifeni lulinganiswa ngee-intshi zegeji yamanzi (WG). Oku kusinika ingcamango yendlela fan enamandla ngayo kwintshukumo yomoya. 

Ukusebenza kwabalandeli kunye noyilo lwe-impeller 

I-Impeller yeyona nto ibalulekileyo yefeni. Leyo yinxenye ehambisa umoya ngokwasemzimbeni. Ii-Impellers ziza kwiimilo ezininzi ezahlukeneyo, kwaye imilo nganye inokuhambisa umoya ngeendlela ezahlukeneyo. Ubume be-impeller bunokunyusa umthamo womoya onokuthi ifeni ikwazi ukuthwala umlinganiselo othile wamandla. 

Ii-Impellers ziza kwiimilo ezahlukeneyo ezibandakanya umva-gophe, phambili-gophe, kunye ne-radial. Iimilo ezahlukeneyo zineenzuzo kunye neengxaki ezahlukileyo, ezichaphazela ukusebenza kakuhle kwefeni. Ezinye iimilo, umzekelo, zinokufaneleka ngcono ukuhambisa umthamo omkhulu womoya ngokukhawuleza, ngelixa ezinye zinokuba ngcono ukonga amandla. 

Ungayikhetha njani iFani eLungileyo usebenzisa uHlahlelo lweCwave yeFan 

Uhlalutyo lwe-fan curve lunokusikhokela ekukhetheni fan efanelekileyo. Oku kusivumela ukuba sithelekise ukusebenza kweefeni ezahlukeneyo ze-centrifugal. Iigophe zabalandeli zisixelela ukuba yintoni na ukuhamba kunye noxinzelelo olunokwenziwa ngumlandeli kumanqanaba ohlukeneyo amandla. Olu lulwazi oluluncedo kakhulu njengoko lusenza sikwazi ukukhetha uhlobo lwefeni oluwufanelekele umsebenzi ongaphambili. 

Kukho izinto ezimbalwa ezibalulekileyo ekufuneka uzigcine engqondweni xa ukhetha fan. Kufuneka sicinge ngeendleko zokuqhuba, ukuba i-fan izakuba nomsindo kangakanani, kwaye iyichaphazela njani indalo esingqongileyo. Uhlalutyo lwegophe labalandeli luvumela ukuba senze ukhetho olungcono olulungelelanisa le miba iphambili. 

Kutheni Abanye Abalandeli Besenza (Kakhulu) ingxolo? 

Ngaba ukhe wayibona indlela abanye abalandeli abakhwaza ngayo kunabanye? Inqanaba lengxolo kwi-fan ye-centrifugal limiselwa zizinto ezahlukeneyo, kubandakanywa noyilo lwe-impeller kunye ne-motor, kunye nesantya sokuhamba komoya. 

Omnye wabanegalelo elikhulu kumanqanaba engxolo kwinkanyamba kukuhamba komoya. Isiphithiphithi senzeke xa umoya udlula kwifeni engenzelwanga ukuvumela umoya ukuba uhambe ngokukhululekileyo. Olu hlobo lwengxolo luphazamisa kakhulu kwaye lunokwenza kube nzima ukuva into engaphaya komzimba wethu. Ukunceda ukunciphisa ingxolo, luluvo olulungileyo ukukhetha iifeni ezakhelwe ukunciphisa isiphithiphithi sokuhamba komoya.
