Bakwane-curve fan curve kunezinye iintlobo zeefeni ze-centrifugal, ezibenza baxhathise ngakumbi kwiinguqu zokuxhathisa inkqubo.
Unokukhetha njani abalandeli be-centrifugal
Isantya sokuhamba komthamo
Izinga lokuqukuqela umthamo sisixa somoya fan unako ukuhamba kwaye ilinganiswa cubic iinyawo ngomzuzu (CFM) okanye cubic metres ngesekhondi (CMS).
Umthamo womthamo ofunekayo uya kuxhomekeka kwisicelo kunye nobukhulu bendawo. Kubalulekile ukuqwalasela indawo yakho kunye neemfuno zexabiso lokuhamba kwevolumu yesicelo xa ukhetha abalandeli be-centrifugal.
Uxinzelelo olungapheliyo
Uxinzelelo lweStatic kukuchasana nokuhamba komoya okubangelwa yi-ductwork, izihluzi, kunye namanye amacandelo kwisistim.
Ifeni kufuneka yoyise uxinzelelo olumileyo ukuhambisa umthamo womoya ofunekayo. Uxinzelelo lwe-static olufunekayo luya kuxhomekeka kwisicelo kunye ne-ductwork kwisistim. Qinisekisa uxinzelelo olumileyo lweenkqubo zakho phambi kokuthenga ifeni ye-centrifugal.
Ukutya umbane
Amandla ombane asetyenzisiweyo ajongwa ngokwamandla ehashe (HP) okanye iiwathi (W) kwaye aya kuxhomekeka kumthamo ofunekayo wevolumu kunye noxinzelelo oluzinzileyo.
Ukukhetha ifeni eyonga amandla kwaye isebenzisa ubuncinci bomthamo wamandla ukuze isebenze kubalulekile ekucutheni iindleko zokusebenza.
Inqanaba lomsindo
Inqanaba lengxolo yefeni lilinganiswa ngeedecibels (dB) kwaye liya kuxhomekeka kwisicelo. Kubalulekile ukukhetha ifeni ezolileyo engayi kuphazamisa indawo efakelwe kuyo.
Qwalasela inqanaba lengxolo kunye nefuthe kubasebenzi abangabantu. Ingxolo ephezulu yabalandeli inokuchaphazela ugxininiso lwabasebenzi kungoko ichaphazela imveliso.
Ubungakanani kunye nokufumaneka kwendawo
Ubungakanani befeni kunye nesithuba esikhoyo sofakelo kufuneka siqwalaselwe xa ukhetha ifeni ye-centrifugal.
