Ifeni evikela ukuqhuma isetshenziswa ezindaweni ezinamagesi avuthayo neziqhumane ukugwema izingozi ezibangelwa izinto ezithile ezivuthayo neziqhumane.Abalandeli bokufakazela ukuqhuma basetshenziswa kakhulu ukufaka umoya, ukukhipha kanye nokupholisa izimboni, izimayini, imigudu, imibhoshongo yokupholisa, izimoto, imikhumbi nezakhiwo.Ukungena komoya kanye nokungenisa umoya kwama-boilers nezithando zomlilo zezimboni;Ukupholisa kanye nokungenisa umoya kwemishini ye-air conditioning nempahla yasendlini;Ukomisa nokukhetha okusanhlamvu;Ukwehla kwamandla emali kanye nokuqhutshwa kwemithombo yomhubhe womoya kanye ne-hovercraft.
Uma kusetshenziswa ifeni yokuvikela ukuqhuma, ingase ihlangabezane nokuthi igesi edlulisayo iqukethe izinto ezivuthayo neziqhumayo, uthuli, intuthu noma izinto eziguquguqukayo.Uma i-motor is short circuited, isekethe inephutha, futhi ukungqubuzana phakathi kwe-fan impeller nezingxenye zayo kukhiqiza izinhlansi, izinto ezihanjiswayo noma amagesi azovutha futhi aqhunyiswe, okuholela ezingozini ezimbi.Ngakho-ke, ukukhethwa kwefeni yokuvikela ukuqhuma kubaluleke kakhulu.Okulandelayo, sizokwethula izinyathelo zokuphepha ezithile zokukhethwa kwefeni elingaqhumi.
Lapho ukhetha ifeni elingaqhume, naka lezi zindaba ezilandelayo:
1. Thola uhlobo lwe-ventilator ngokwezinjongo ezahlukene.Isibonelo, lapho uletha umoya ohlanzekile, ama-ventilators ajwayelekile angakhethwa ukuze kungene umoya;Ama-anticorrosive ventilators azosetshenziswa lapho kuthuthwa amagesi ezonakalisayo;I-ventilator engaqhumeki noma isikhipha umoya esikhipha uthuli kufanele kukhethwe lapho uhambisa i-ventilator evuthayo noma umoya onothuli.
2. Thola imodeli yabalandeli ngokuya ngevolumu yomoya edingekayo, uthuli kanye nohlobo lwabalandeli olukhethiwe.
3. Ukuze kube lula ukuxhunywa nokufakwa kwamafeni namapayipi esistimu, indlela efanele yokuphuma kwefeni kanye nemodi yokudlulisela kuyokhethwa.
Imodeli yefeni elingaqhumi izokhethwa ngokuya ngesimo sangempela sesitshalo, futhi imodeli yabalandeli ehambisana nosayizi wewindi langempela izokhethwa ngokusemandleni akho.I-fan kufanele igcinwe ebangeni elithile ukusuka ekhethini elimanzi (elifakwe ezinhlangothini zombili ze-gable yesitshalo ngangokunokwenzeka) ukuze kuzuzwe umphumela omuhle wokungenisa umoya.Zama ukugcina uhlangothi lwe-exhaust kude nezakhiwo eziseduze ukuze ungathinti izakhamuzi eziseduze.
Ngokombono wefeni, ifeni yokuvikela ukuqhuma iqhutshwa injini ukuze ikhiqize amandla omoya.Imisebenzi ehlukene yefeni esalungiswa esungulwe inqunywa izingxenye ezifakiwe.Eyokuqala itholakala ekugcineni kwebhayela, ivuthela umoya ku-flue ngaphandle kwebhayela ukuze kukhiqizwe ingcindezi engemihle esithandweni somlilo kanye negesi eqondisayo ye-flue, ngakho-ke ibizwa ngokuthi i-induced draft fan;Ngokuphambene nalokho, lesi sakamuva sitholakala ekugcineni kwe-boiler futhi sivuthela umoya ku-boiler, ngakho-ke kubizwa ngokuthi i-blower.
Uma isiphephetha-moya esingaqhumi sisebenza ngokujwayelekile, umsindo awukwazi ukususwa.Ucwaningo lubonisa ukuthi inqobo nje uma isivinini somoya singaphezu kuka-0.75 m/s, umsindo uzokwenziwa.Kunjalo, lapho isivinini somoya siphansi, umsindo uyancipha.Umsindo uwukungcola okuyingozi.Ingabe akusho ukuthi lapho umsindo uphansi, kungcono?Umsindo ophansi muhle, kodwa umnotho wayo kumele ubhekwe.Lapho umsindo uphansi odingekayo, izindleko zesiphephetha-moya ezidingekayo.Kukho konke ukuncishiswa okungu-10 dB, izindleko zefeni zizophindeka kabili (inani le-empirical, elingelona umugqa).Umsindo okhawulelwe wabalandeli abaningi akufanele ube ngaphansi kuka-35dBA.Ngakho-ke, akudingekile ukuphishekela umsindo ophansi lapho ukhetha abalandeli, inqobo nje uma kungaphakathi kwebanga elinengqondo nelimukelekayo.
