Mosiyana ndi zinthu zina, zimakupiza nthawi zambiri zimakhala ndi moyo wautumiki wazaka zingapo kapena kupitilira zaka khumi, ndipo mtengo wake umasiyana. Choncho, posankha fani, tiyenera kusankha imodzi yomwe ili yoyenera komanso yomwe ili ndi chiŵerengero chokwera mtengo. Lero, tiyeni tiphunzire za mfundo zazikuluzikulu posankha fan. Choyamba, potengera magawo awiri ofunikira a fani yofunikira - kuchuluka kwa mpweya ndi kuthamanga kwa mpweya, dziwani chitsanzo ndi chiwerengero cha fani, komanso mphamvu yofunikira kudzera pa tebulo la ntchito (mabuku onse opangira mafani ali ndi deta yoyenera). Panthawiyi, pakhoza kukhala mankhwala oposa amodzi omwe amakwaniritsa zofunikira; Kenako timaphatikiza cholinga cha fan, zomwe zimafunikira pakugwirira ntchito, ndi momwe zimagwirira ntchito (malo ogwiritsira ntchito) kuti tisankhe mtundu, mtundu, kapangidwe kake, ndi zinthu za fan kuti zikwaniritse zofunikira zogwirira ntchito. Timayesetsa kuti mayendedwe oyendetsedwa ndi kukakamizidwa kwa faniyo akhale pafupi ndi momwe tingathere ndi kuthamanga ndi kukakamizidwa kofunikira ndi ndondomekoyi, kotero kuti malo ogwiritsira ntchito faniyo ali pafupi ndi malo ogwira ntchito a mawonekedwe a fan. Mfundo zenizeni ndi izi:
Asanasankhe zimakupiza, munthu ayenera kudziwiratu za kupanga ndi mtundu wa zida mpweya mpweya ku China, kuphatikizapo mitundu, specifications opangidwa mafani, ndi ntchito yeniyeni zinthu zosiyanasiyana. Ayeneranso kumvetsetsa momwe msika wa mafani aku China ulili.
② Kutengera momwe gasi amayendera komanso momwe amapangira mankhwala, sankhani makina olowera mpweya oyenera kuchita zomwe akufuna. Mwachitsanzo, ngati kutumizira mpweya wophulika kapena woyaka, payenera kusankhidwa chothandizira kuti sungaphulike fumbi, ndipo mulingo wotsimikizira kuphulika wa fani udziwike; ngati ndi yochotsa fumbi kapena kunyamula ufa wa malasha, chochotsa fumbi kapena mpweya wa malasha uyenera kusankhidwa; ngati ndi yotumiza mpweya wowononga, payenera kusankhidwa chothandizira kuti chisachite dzimbiri, ndipo zinthu zoteteza ku dzimbiri (monga pulasitiki yolimba ya fiberglass kapena PP) ziyenera kutsimikiziridwa; ngati ikugwira ntchito kumalo otentha kwambiri kapena kutulutsa mpweya wotentha kwambiri, mpweya wotentha kwambiri uyenera kusankhidwa, ndipo kutentha kwa chilengedwe ndi kutentha kwa gasi wotumizidwa ziyenera kumveka.
③ Ngati pali mitundu yopitilira iwiri yamagetsi yomwe ilipo pa tchati cha magwiridwe antchito, yomwe ili ndi magwiridwe antchito apamwamba, kukula kocheperako komanso kusintha kokulirapo iyenera kuperekedwa patsogolo. Zoonadi, mungathenso kufananiza ndi zotsika mtengo ndikupanga chisankho poyesa ubwino ndi kuipa.
④ Ngati mainchesi a chopondera chosankhidwa ndi chokulirapo kuposa cha chopondera choyambirira, kuti mugwiritse ntchito shaft yoyambira, mayendedwe, ndi zothandizira, ndikofunikira kuwerengera nthawi yoyambira, mphamvu ya zida zoyambira, komanso liwiro lozungulira la shaft.
⑤ Posankha chowotcha chapakati, ngati mphamvu yagalimoto yomwe ili nayo ndi yochepera kapena yofanana ndi 75KW, valavu yoyambira yokhayo siyingayikidwe. Posankha chowotcha cha centrifugal chotulutsa mpweya kuti chitulutse mpweya wotentha kapena mpweya, valavu yoyambira iyenera kuperekedwa kuti mupewe kuchulukirachulukira panthawi yozizira.
⑥ Pamakina opumira mpweya okhala ndi zofunikira zaphokoso, kusankha kuyenera kuyamba ndi ma ventilator omwe ali ndi mphamvu zambiri komanso kuthamanga kwapang'onopang'ono kwa chowongoleracho, ndikugwira ntchito pamalo awo opambana. Njira zofananira zochepetsera phokoso ndi zochepetsera kugwedezeka ziyenera kuchitidwanso potengera momwe phokoso ndi kugwedezeka kopangidwa ndi makina olowera mpweya zimafalikirira. Njira zochepetsera kugwedezeka kwa ma ventilator ndi ma motors nthawi zambiri zimatha kutheka kudzera pamaziko ochepetsera kugwedezeka, ndipo zida zochepetsera kugwedera zitha kusankhidwa kutengera njira yoyikitsira ma ventilator.
⑦ Posankha makina olowera mpweya, ndikofunikira kupewa kugwiritsa ntchito ma ventilator mu ntchito yofanana kapena yotsatizana. Ngati ntchito yotereyi ndi yosapeŵeka, ndi bwino kusankha ma ventilator a chitsanzo chomwecho ndi ntchito yofanana kuti agwire ntchito pamodzi. Mukamagwiritsa ntchito maulumikizidwe angapo, payenera kukhala kulumikizana kwa mapaipi pakati pa gawo loyamba ndi lachiwiri la zolumikizira mpweya.
