Ifeni yobungqina bokudubula isetyenziswa kwiindawo ezinerhasi ezinokutsha neziqhumayo ukunqanda iingozi ezibangelwa zizinto ezinokutsha neziqhumayo.Abalandeli bobungqina boqhushumbo basetyenziselwa kakhulu ukungena komoya, ukukhupha kunye nokupholisa iifektri, imigodi, iitonela, iinqaba zokupholisa, izithuthi, iinqanawa kunye nezakhiwo.Ukungena komoya kunye nokungenisa umoya kwiibhoyili kunye neziko zoshishino;Ukupholisa kunye nokungenisa umoya wezixhobo zomoya kunye nezixhobo zendlu;Ukomisa kunye nokukhetha iinkozo;Ukunyuka kwamaxabiso kunye nokuqhutyelwa kwemithombo yetonela yomoya kunye ne-hovercraft.
Xa i-fan-proof-proof isetyenziswa, inokudibana nokuba igesi ehambisayo iqulethe izinto ezinokutsha kunye neziqhushumbisi, uthuli, umsi okanye izinto eziguqukayo.Xa i-motor is short circuited, i-circuit iphosakele, kwaye ingxabano phakathi kwe-fan impeller kunye neendawo zayo zivelisa iintlantsi, izinto ezithuthwayo okanye iigesi ziya kutshiswa kwaye zihlanjululwe, kubangele iingozi ezinzulu.Ke ngoko, ukukhethwa kwefeni yobungqina bokudubula kubaluleke kakhulu.Okulandelayo, siza kwazisa ezinye izilumkiso zokhetho lwefeni yobungqina bokudubula.
Xa ukhetha ifeni yokuthintela uqhushumbo, qwalasela le miba ilandelayo:
1. Qinisekisa uhlobo lwe-ventilator ngokweenjongo ezahlukeneyo.Ngokomzekelo, xa uhambisa umoya ococekileyo, ii-ventilators eziqhelekileyo zingakhethwa ukungena komoya;Ii-anticorrosive ventilators ziya kusetyenziswa xa kuhanjiswa iigesi ezitshabalalisayo;Isixhobo sokungenisa umoya esithintela uqhushumbo okanye isikhupha-moya sokukhupha uthuli siya kukhethwa xa uhambisa i-ventilator enokutsha okanye umoya onothuli.
2. Misela imodeli ye-fan ngokomthamo womoya ofunekayo, uthuli kunye nohlobo olukhethiweyo lwabalandeli.
3. Ukuze kuququzelelwe uqhagamshelo kunye nofakelo lweefeni kunye nemibhobho yesistim, indlela efanelekileyo yokuphuma kwefeni kunye nemodi yothumelo iya kukhethwa.
Imodeli yefeni yokumelana nokudubula iya kukhethwa ngokweyona meko yomatshini, kwaye imodeli yefeni ehambelana nobungakanani befestile yoqobo iya kukhethwa kangangoko kunokwenzeka.Ifeni iya kugcinwa kumgama othile ukusuka kwikhethini emanzi (efakwe kumacala omabini egayibhile yesityalo kangangoko kunokwenzeka) ukufikelela kwisiphumo esihle sokungenisa umoya.Zama ukugcina icala lokukhupha kude nezakhiwo ezikufutshane ukuze ungachaphazeli abahlali abakufutshane.
Ngokwembono yefeni, fan-proof-proof fan iqhutywa yimoto ukuvelisa amandla omoya.Imisebenzi eyahlukeneyo yedrafti yedrafti yefeni imiselwa ngamacandelo afakiweyo.Eyangaphambili ikwisiphelo esingasemva sebhoyila, ivuthela umoya kwibhoyila ngaphandle kwebhoyila ukuvelisa uxinzelelo olubi kwiziko kunye negesi ekhokelayo yeflue, ngoko ibizwa ngokuba yidrafti yedrafti fan;Ngokuchasene noko, le yokugqibela ikwisiphelo esingaphambili sebhoyila kwaye ivuthela umoya kwibhoyila, ngoko ibizwa ngokuba yi-blower.
Xa i-fan-proof-proof fan isebenza ngokuqhelekileyo, ingxolo ayikwazi ukupheliswa.Uphando lubonisa ukuba nje ukuba isantya somoya singaphezulu kwe-0.75 m/s, ingxolo iya kwenziwa.Ngokuqinisekileyo, isantya somoya sisezantsi, ingxolo encinci iya kuveliswa.Ingxolo lungcoliso oluyingozi.Ngaba ayithethi ukuba okukhona ingxolo isezantsi, kokukhona ingcono?Ingxolo ephantsi ilungile, kodwa uqoqosho lwayo kufuneka luthathelwe ingqalelo.Okukhona isezantsi ingxolo efunekayo, kokukhona ixabiso lefeni liphezulu elifunekayo.Kuwo wonke ukuncipha kwe-10 dB, iindleko zefeni ziya kuphinda kabini (ixabiso le-empirical, elingenalo umgca).Ingxolo elinganiselweyo yabalandeli abaninzi ayiyi kuba ngaphantsi kwe-35dBA.Ngoko ke, akuyimfuneko ukulandela ingxolo ephantsi xa ukhetha abalandeli, ngokude nje kuphakathi koluhlu olufanelekileyo nolwamkelekileyo.
