1. Nzira yekusarudza fan fan?
Mafeni maindasitiri anogona kushandiswa kune zvakawanda zvinangwa uye ane akasiyana masisitimu:
-Integrated fan
-Duct fan
-Portable fan
-Electric cabinet fan
-Vamwe.
Danho rekutanga nderekuona mhando yefani inodiwa.
Sarudzo yetekinoroji inowanzoitwa pakati peaxial flow fan uye centrifugal fan.Muchidimbu, axial kuyerera mafeni anogona kupa kuyerera kwemhepo uye kuderera kwakadzika, saka ivo vakakodzerwa chete nekushomeka kudonha (pfupi wedunhu) maapplication, nepo centrifugal mafeni anonyanya kukodzera kudonha kwepamusoro (kureba kwedunhu) application.Axial kuyerera mafeni zvakare anowanzo tsikitsira uye ane ruzha pane akaenzana centrifugal mafeni.
Mafeni anosarudzwa kuti ape humwe huwandu hwemhepo (kana gasi) pane imwe nhanho yekumanikidza.Kune akawanda maapplication, kusarudzwa kuri nyore uye chiyero chekuyerera chinoratidzwa nemugadziri chakakwana kuverenga saizi ye fan.Mamiriro acho anowedzera kuoma kana fan yakabatana nedunhu (ventilation network, air supply kune burner, etc.).Kuyerera kwemhepo kunounzwa nefani kunoenderana nehunhu hwayo uye zvakare zvinoenderana nekudonha kwekumanikidza kwedunhu.Iyi ndiyo musimboti wenzvimbo yekushanda: kana iyo fan inoyerera kumanikidza curve uye loop kuyerera kudzvinyirira kurasikirwa curve yakadhirowewa, nzvimbo yekushanda yefani mudunhu rino ichave iri pamharadzano yemacurves maviri.
Kunyangwe mafeni mazhinji anoshanda pakamuri tembiricha, mamwe mafeni anofanira kushanda pane chaiyo tembiricha kana mamiriro ekunze.Izvi ndizvo zvakaita, semuenzaniso, nefan inotenderera muchoto.Naizvozvo, zvakakosha kuti usarudze mhando dzakasiyana dzevateveri zvinoenderana neakasiyana maapplication.
2, Sei uchisarudza spiral fan?
Iyo spiral fan (kana axial flow fan) inoumbwa nepropeller ine injini inotenderera paaxis yayo.Iyo propeller inosaidzira kuyerera kwemhepo kunoenderana neakisi yayo yekutenderera.
Iyo spiral fan inogona kupa kuyerera kwemhepo yakakwira, asi kudzvanywa pakati pekumusoro nezasi hakuna kumbowedzera.Nemhaka yokuti kuwandisa kwakanyanyisa, kushandiswa kwavo kunogumira kune pfupi pfupi inokonzerwa nekuderera kwepasi.
Axial mafeni kazhinji ane maviri kusvika makumi matanhatu mablades.Kubudirira kwayo kuri 40% kusvika 90%.
Iyi fan inowanzo shandiswa kutenderera kwemhepo mumakamuri makuru, kuburikidza nemadziro emhepo uye duct ventilation mumakamuri.
Kuenzaniswa neiyo centrifugal fan, iyo spiral fan inotora nzvimbo shoma, inodhura zvishoma uye ine ruzha rwakaderera.
3, Sei uchisarudza centrifugal fan?
Iyo centrifugal fan (kana runoff fan) ine vhiri re fan (impeller), iyo inofambiswa nemota inotenderera mu stator yakabatana kune impeller.Iyo stator ine mazaru maviri: yekutanga kuvhura inopa fluid kune yepakati chikamu che impeller, iyo fluid inopinda kuburikidza ne vacuum, uye yechipiri kuvhura inovhuvhuta kumucheto kuburikidza ne centrifugal chiito.
Kune mhando mbiri dze centrifugal mafeni: kumberi bend fan uye kumashure bend fan.Iyo yekumberi yakakomberedzwa centrifugal fan ine "squirrel cage" impeller uye 32 kusvika 42 blades.Kubudirira kwayo kuri 60% kusvika 75%.Kushanda kweiyo kumashure curved centrifugal fan ndeye 75% kusvika 85%, uye nhamba yemablades ndeye 6 kusvika 16.
Iyo overpressure yakakwira kupfuura iyo spiral fan, saka centrifugal fan inonyanya kukodzera kutenderera refu.
Mafeni eCentrifugal anewo mukana maererano nemazinga eruzha: ivo vakanyarara.Nekudaro, zvinotora nzvimbo yakawanda uye inodhura kupfuura spiral cyclone.
4, Nzira yekusarudza feni yemagetsi?
Mafeni emagetsi akakwana uye akavharirwa mafeni ane zviyero zvakajairwa uye magetsi ekupa (AC kana DC) kuitira kusanganisa nyore muyakavharirwa.
Iyo fan inoshandiswa kubvisa kupisa kunogadzirwa nemagetsi emagetsi muvharo.Sarudza maererano nemamiriro anotevera:
Air displacement
volume
Supply voltage inowanikwa mune yakavharirwa
Nekuda kwekubatana, mafeni mazhinji emagetsi mafeni espiral, asi kune zvakare centrifugal uye diagonal kuyerera mafeni, ayo anogona kupa yakakwirira kuyerera kwemhepo.
5, Maitiro ekusarudza mafeni emagetsi kabati?
Iyo yemagetsi kabati fan inogona kuvhuvhuta mweya unotonhora mukati mekabati kuti idzore tembiricha yemidziyo yemagetsi.Vanodzivirira huruva kupinda mukhabhineti nekugadzira kuwedzeredza kudiki.
Kazhinji, mafeni aya akaiswa pamusuwo kana pamadziro emadziro ekhabhineti uye akabatanidzwa mukati meiyo ventilation network.Kune zvakare mamwe mamodheru anogona kuiswa pamusoro pekabati.Vakashongedzerwa nemasefa ekudzivirira huruva kupinda mu cabinet.
Kusarudzwa kwefani iyi kunoenderana ne:
Air displacement
Cabinet inopa voltage
Kubudirira kwesefa
