Kugwiritsa ntchito ndi mawonekedwe a fan-proof fan

Fani yotsimikizira kuphulika imagwiritsidwa ntchito m'malo okhala ndi mpweya woyaka komanso wophulika kuti apewe ngozi zobwera chifukwa cha zinthu zina zoyaka komanso zophulika.Mafani otsimikizira kuphulika amagwiritsidwa ntchito kwambiri popumira mpweya, kuchotsa ndi kuziziritsa mafakitale, migodi, tunnel, nsanja zozizirira, magalimoto, zombo ndi nyumba.mpweya wabwino ndi mpweya wa boilers ndi ng'anjo mafakitale;Kuziziritsa ndi mpweya wabwino wa zipangizo zoziziritsira mpweya ndi zipangizo zapakhomo;Kuyanika ndi kusankha mbewu;Kukwera kwamitengo ndi kuthamangitsidwa kwa magwero amphepo ndi hovercraft.
Fani yoteteza kuphulika ikagwiritsidwa ntchito, imatha kukumana kuti gasi wotumizayo ali ndi zinthu zoyaka komanso zophulika, fumbi, utsi kapena zinthu zosakhazikika.Pamene galimoto imakhala yochepa, dera limakhala lolakwika, ndipo kukangana pakati pa fani ya fani ndi ziwalo zake kumatulutsa zopsereza, zinthu zomwe zimanyamulidwa kapena mpweya zidzayatsidwa ndikuphulika, zomwe zimabweretsa ngozi zoopsa.Choncho, kusankha kwa fan-proof fan ndikofunikira kwambiri.Kenako, tikuwonetsani njira zodzitetezera posankha chofanizira chosaphulika.
Posankha chofanizira chosaphulika, samalani ndi izi:
1. Dziwani mtundu wa mpweya wabwino molingana ndi zolinga zosiyanasiyana.Mwachitsanzo, popereka mpweya wabwino, ma ventilator ambiri amatha kusankhidwa kuti azipumira;Ma anticorrosive ventilators ayenera kugwiritsidwa ntchito ponyamula mpweya wowononga;Mpweya wosaphulika wosaphulika kapena mpweya wotulutsa fumbi udzasankhidwa popereka mpweya woyaka kapena mpweya wafumbi.
2. Dziwani chitsanzo cha fani malinga ndi kuchuluka kwa mpweya wofunikira, fumbi ndi mtundu wosankhidwa.
3. Kuti athe kulumikiza ndi kukhazikitsa mafani ndi mapaipi a dongosolo, njira yoyenera yotulutsira mafani ndi njira yopatsira idzasankhidwa.
Mtundu wa fan wosaphulika udzasankhidwa molingana ndi momwe mbewuyo ilili, ndipo chofanizira chofanana ndi kukula kwazenera koyambirira chidzasankhidwa momwe kungathekere.Chophimbacho chiyenera kusungidwa pamtunda wina kuchokera pa nsalu yonyowa (yoyikidwa mbali zonse za gable ya zomera momwe zingathere) kuti akwaniritse mpweya wabwino.Yesetsani kuti mbali yotulutsa mpweya ikhale kutali ndi nyumba zapafupi kuti zisakhudze okhala pafupi.
Kuchokera pamalingaliro a fan, fan yotsimikizira kuphulika imayendetsedwa ndi mota kuti ipange mphamvu yamphepo.Ntchito zosiyanasiyana za fan fan zomwe zimapangidwira zimatsimikiziridwa ndi zigawo zomwe zayikidwa.Yoyamba ili kumapeto kwenikweni kwa kukatentha, kuwomba mpweya mu chitoliro kunja kwa kukatentha kutulutsa kupsyinjika zoipa pa ng'anjo ndi kalozera chitoliro mpweya, choncho amatchedwa anachititsa njanji zimakupiza;M'malo mwake, chotsiriziracho chili kumapeto kwa chowotchera ndikuwomba mpweya mu boiler, motero amatchedwa chowombera.
Pamene fani yoteteza kuphulika imagwira ntchito bwino, phokoso silingathe kuthetsedwa.Kafukufuku akuwonetsa kuti bola ngati mphepo ikudutsa 0.75 m / s, phokoso lidzapangidwa.Inde, kutsika kwa liwiro la mphepo, phokoso lochepa lidzapangika.Phokoso ndi kuipitsa kovulaza.Kodi sizikutanthauza kuti m'munsi phokoso limakhala bwino?Phokoso lotsika ndi labwino, koma chuma chake chiyenera kuganiziridwa.Phokoso likatsika, ndiye kuti mtengo wa faniyo umakwera kwambiri.Pakuchepetsa kulikonse kwa 10 dB, mtengo wa faniyo umawirikiza kawiri (mtengo wamphamvu, wopanda mzere).Phokoso lochepera la mafani ambiri siliyenera kutsika kuposa 35dBA.Choncho, sikoyenera kutsata phokoso lochepa posankha mafani, malinga ngati ali mkati mwazovomerezeka komanso zovomerezeka.
