Indlela yokukhetha ifeni efanele

1. Ungakhetha kanjani fan yezimboni?

Abalandeli bezimboni bangasetshenziselwa izinhloso eziningi futhi babe nokucushwa okuhlukahlukene:

- I-fan ehlanganisiwe

- I-fan ye-duct

-Fani ephathekayo

- Umlandeli wekhabhinethi kagesi

-Abanye.

Isinyathelo sokuqala ukunquma uhlobo lwefeni oludingekayo.

Ukukhethwa kobuchwepheshe kuvame ukwenziwa phakathi kwe-axial flow fan ne-centrifugal fan.Ngamafuphi, abalandeli be-axial flow banganikeza ukugeleza komoya okuphezulu kanye nokucindezela okuphansi, ngakho-ke bafaneleka kuphela ukwehla kwengcindezi ephansi (i-short circuit) izicelo, kuyilapho abalandeli be-centrifugal befaneleka kakhulu ukwehla kwengcindezi ephezulu (isifunda eside).Abalandeli be-axial flow nabo ngokuvamile baminyene futhi banomsindo kunabalandeli be-centrifugal abalinganayo.

Abalandeli bakhethwa ukunikeza inani elithile lomoya (noma igesi) ezingeni elithile lokucindezela.Ezinhlelweni eziningi, ukukhetha kulula futhi izinga lokugeleza elikhonjiswe umenzi lanele ukubala usayizi wabalandeli.Isimo siba nzima kakhulu lapho umshayeli exhunywe kumjikelezo (inethiwekhi ye-ventilation, ukunikezwa komoya ku-burner, njll.).Ukugeleza komoya okulethwa yi-fan kuncike ezicini zayo futhi kuncike ekunciphiseni kokucindezela kwesekethe.Lona umgomo wephuzu lokusebenza: uma ijika lokucindezela kokugeleza kwabalandeli kanye nejika lokulahlekelwa kokucindezela kokugeleza kwe-loop lidwetshwa, indawo yokusebenza yefeni kule sekethi izotholakala empambanweni yamajika amabili.

Nakuba abalandeli abaningi besebenza ekamelweni lokushisa, abanye abalandeli kufanele basebenze ezingeni lokushisa elithile noma izimo zemvelo.Lokhu kunjalo, isibonelo, nge-fan ejikelezayo kuhhavini.Ngakho-ke, kubalulekile ukukhetha izinhlobo ezahlukene zabalandeli ngokusho kwezicelo ezahlukene.

2, Kungani ukhethe fan Kuvunguza?

I-spiral fan (noma i-axial flow fan) yakhiwe ngophephela injini yayo ezungeza ku-eksisi yayo.I-propeller iphusha ukugeleza komoya ngokuhambisana ne-eksisi yayo yokuzungeza.

Ifeni elivunguzayo linganikeza ukugeleza komoya okuphezulu, kodwa ukucindezela phakathi komfula okhuphuka nomfula ongezansi akhulanga neze.Ngenxa yokuthi i-overpressure iphansi kakhulu, ukusetshenziswa kwabo kunqunyelwe kumjikelezo omfushane obangelwa ukwehla kwengcindezi ephansi.

Abalandeli be-Axial ngokuvamile banama-blade angu-2 kuya kwangu-60.Ukusebenza kwayo kungama-40% kuya ku-90%.

Le fan ngokuvamile isetshenziselwa ukujikeleza komoya emakamelweni amakhulu, ngokungenisa umoya odongeni kanye nokungenisa umoya emakamelweni.

Uma iqhathaniswa nefeni ye-centrifugal, ifeni evunguzayo ithatha indawo encane, ibiza kancane futhi inomsindo ophansi.

3, Kungani ukhethe fan centrifugal?

I-centrifugal fan (noma i-runoff fan) iqukethe isondo labalandeli (i-impeller), eliqhutshwa injini ezungeza ku-stator exhunywe ku-impeller.I-stator inezimbobo ezimbili: ukuvulwa kokuqala kunikeza uketshezi engxenyeni emaphakathi ye-impeller, uketshezi lungena nge-vacuum, futhi ukuvulwa kwesibili kushaye onqenqemeni ngesenzo se-centrifugal.

Kunezinhlobo ezimbili zabalandeli be-centrifugal: i-front bend fan ne-back bend fan.Ifeni ye-centrifugal egobile phambili ine-impeller "yekheji yesquirrel" kanye nama-blade angama-32 kuye kwangama-42.Ukusebenza kwayo kungama-60% kuya ku-75%.Ukusebenza kahle kwefeni ye-centrifugal egobile emuva kungu-75% kuya ku-85%, futhi inani lama-blades ngu-6 kuya ku-16.

I-overpressure iphakeme kunaleyo ye-spiral fan, ngakho-ke ifeni ye-centrifugal ifaneleka kakhulu kumjikelezo omude.

Abalandeli be-Centrifugal nabo banenzuzo ngokuya ngamazinga omsindo: bathule.Nokho, kuthatha isikhala esiningi futhi kubiza ngaphezu kwesishingishane esivunguzayo.

4. Ungakhetha kanjani i-fan electronic?

Abalandeli bakagesi bangabalandeli abahlangene futhi abavalekile abanobukhulu obujwayelekile kanye nama-voltage okuhlinzeka (AC noma i-DC) ukuze bahlanganiswe kalula endaweni ebiyelwe.

Ifeni isetshenziselwa ukuqeda ukushisa okukhiqizwa izingxenye ze-elekthronikhi endaweni ebiyelwe.Khetha ngokuya ngemibandela elandelayo:

Ukususwa komoya

umthamo

I-voltage yokuhlinzeka iyatholakala endaweni ebiyelwe

Ngenxa yokubumbana, abalandeli abaningi be-elekthronikhi bangabalandeli be-spiral, kodwa kukhona nabalandeli be-centrifugal kanye ne-diagonal flow, abangahlinzeka ngokugeleza komoya okuphezulu.

5. Ungakhetha kanjani abalandeli bekhabethe likagesi?

Ifeni yekhabhinethi kagesi ingavuthela umoya obandayo ekhabetheni ukuze ilawule izinga lokushisa lemishini kagesi.Bavimbela uthuli ukuthi lungangeni ekhabetheni ngokudala ukucindezela okuncane kakhulu.

Ngokuvamile, laba abalandeli bafakwe emnyango noma odongeni oluhlangothini lwekhabhinethi futhi bahlanganiswe kunethiwekhi yokungenisa umoya.Kukhona futhi amamodeli athile angafakwa phezulu kwekhabhinethi.Afakwe izihlungi ukuvimbela uthuli ukuba lungene ikhabhinethi.

Ukukhethwa kwalo mlandeli kusekelwe kulokhu:

Ukususwa komoya

I-voltage yokuhlinzeka ngeKhabhinethi

Ukusebenza kwesihlungi
