Dongosolo lamagetsi lobowola mafuta makamaka limachokera ku injini za dizilo. Mphamvu zamainjini a dizilo ndizokulirapo, nthawi zambiri pafupifupi 800KW. Makina obowola a 5000M nthawi zambiri amafunikira injini zitatu za dizilo ndipo seti ya 3M pobowola yopangira nthawi zambiri imafunikira injini zinayi za dizilo. Ma injini a dizilo amatulutsa phokoso akamagwira ntchito, makamaka ma injini a dizilo omwe amagwiritsidwa ntchito pobowola. Chifukwa cha mphamvu zawo zapamwamba komanso kuyanjana, phokoso limakhala lodziwika kwambiri. Phokoso la injini ya dizilo limamveka ngakhale kutchire komanso patali kwambiri.
- Kusanthula kwa magwero a phokoso la seti ya jenereta ya dizilo
Panthawi yogwiritsira ntchito dizilo, kusokonezeka kwa mpweya kumayambitsa phokoso pakati pa mpweya ndi dizilo kuti apange phokoso. Phokoso lamtundu wotere limatulukira kunja, makamaka kuphatikiza: phokoso la makina otulutsa mpweya, phokoso la mpweya wotengera mpweya, ndi phokoso lozungulira la fan yoziziritsa ya dizilo.
(1) Phokoso la dongosolo la utsi. Phokoso lachindunji kwambiri la seti ya jenereta ya dizilo ndi phokoso lomwe limapangidwa ndi makina otulutsa. Phokosoli ndi lamphamvu kwambiri ndipo ndi pafupifupi 10 ~ 15dB (A) kuposa phokoso la injini. Panthawi yogwiritsira ntchito jenereta, mpweya wotentha kwambiri komanso wothamanga kwambiri uyenera kutulutsidwa mosalekeza. Malingana ndi momwe ntchito ya jenereta imagwirira ntchito, makina otulutsa mpweya ali ndi magawo awiri a mpweya, zomwe ndizo kutulutsa kwaulere kwa seti ya jenereta ndi kukakamiza kutulutsa kwa seti ya jenereta. Pamene mpweya wotulutsa mpweya wochokera ku jenereta umatulutsidwa kuchokera ku valavu yotulutsa mpweya, umayenda kuchokera ku chitoliro chotulutsa mpweya kupita ku muffler, ndipo pamapeto pake udzatulutsidwa mumlengalenga kupyolera mu chitoliro chakumbuyo chakumbuyo. Pa nthawi yonse yotulutsa mpweya, phokoso lalikulu la mpweya lidzapangidwa, lomwe limakhalanso gwero lalikulu la phokoso lochokera ku seti ya jenereta ya dizilo. Phokoso lomwe linapangidwa panthawi yotulutsa mpweya linafufuzidwa ndipo zinapezeka kuti mapangidwe a phokosolo anali ovuta kwambiri. Pali maphokoso omwe amayamba chifukwa cha kuchuluka kwa ntchito zotulutsa mpweya pa nthawi ya unit, phokoso lomwe limadza chifukwa cha kutulutsa kwa mpweya wotulutsa mpweya mu chitoliro chotulutsa mpweya, komanso phokoso lophulika lomwe limayambitsidwa ndi kutuluka kwa mpweya kuchokera ku chitoliro chotulutsa mpweya. Zinthu zazikulu zimene zingakhudze phokoso la dongosolo utsi wa jenereta akonzedwa ndi: kuthamanga mkati mwa yamphamvu injini, ndi chitoliro awiri a dongosolo utsi, oveteredwa utsi voliyumu ya seti jenereta, liwiro ntchito ndi katundu wa jenereta akonzedwa, etc. Kuonjezera katundu ntchito jenereta anapereka kapena kuonjezera liwiro la injini otaya, kuonjezera mpweya wotuluka, kuonjezera mpweya wotuluka.
(2) Phokoso lochokera m’njira yotengera mpweya. Phokoso lopangidwa ndi makina otengera mpweya ndi limodzi mwamaphokoso akuluakulu a seti ya jenereta ya dizilo. Chifukwa chachikulu cha mapangidwewo ndikuti mpweya wolowera mpweya umatsegulidwa mosalekeza ndikutsekedwa molingana ndi kufunikira kwa mpweya wa jenereta, zomwe zimapangitsa kuti kupanikizika kwa kayendedwe ka mpweya kumasintha mosalekeza ndikupangitsa phokoso. Dongosolo lamadyetsero likamagwira ntchito, kugunda kwina kwina kumapangidwa mu chitoliro cholowetsa, zomwe zimapangitsa kuti njira yolowera ipange phokoso lanthawi ndi nthawi. Ma frequency amtundu wa phokosoli nthawi zambiri amakhala pafupifupi 200Hz. Panthawi imodzimodziyo, pamene mpweya umalowa mkati mwa dongosolo, umadutsa muipi yolowetsa mpweya, zomwe zimapangitsa kuti mpweya utuluke m'thupi. Izi zipangitsa phokoso lambiri pamakina otengera mpweya wa injini. Nthawi zambiri mpweya wotuluka mu chitoliro cholowetsamo umasintha nthawi zonse, kotero kuti ma frequency a phokoso amakhazikikanso, nthawi zambiri amakhala mozungulira 1000Hz. Pamene phokoso lafupipafupi la kayendedwe ka kudya ndi mpweya wa mpweya mu dongosolo lodyera lifika kugwirizana, kuphulika kwa mpweya kudzachitika, zomwe zimapangitsa kuti phokoso la dongosolo lodyera liwonjezeke. Phokoso lopangidwa ndi ma supercharger osiyanasiyana m'magulu osiyanasiyana a jenereta ndi losiyananso. Kuchuluka kwa phokoso la seti ya jenereta ya turbocharged mwachiwonekere ndi yosiyana poyerekeza ndi jenereta yopanda turbocharged. Izi zimachitika chifukwa cha liwiro lapamwamba la seti ya jenereta ya turbocharged, yomwe imapangitsa kuti makina otengera mpweya wa injini atulutse mpweya wamphamvu chifukwa cha kudula kwa mpweya, zomwe zimapangitsa kuti pakhale phokoso lambiri. Kugawa pafupipafupi kwa phokosoli nthawi zambiri kumakhala pakati pa 500 ndi 10000Hz.
1.2 Phokoso lochokera kumtunda
Kunena zoona, n'zovuta kusiyanitsa phokoso lapamwamba la phokoso la seti ya jenereta ya dizilo. Phokoso la kuyaka nthawi zambiri limayamba chifukwa cha kugwedezeka kwamphamvu komwe kumapangidwa ndi kuyaka kwa dizilo mkati mwa silinda yomwe imagwira ntchito pamakina a silinda yonseyo, motero kumatulutsa phokoso lakunja. Panthawi yogwiritsira ntchito jenereta, zigawo zosiyanasiyana zamakina zidzapitiriza kugundana ndi makina, motero zimapanga phokoso lamakina. Kawirikawiri, pamene jenereta anapereka liwiro ndi otsika, kuyaka phokoso kwaiye ndi apamwamba kuposa makina phokoso.
- Njira zopangira zochepetsera phokoso m'zipinda za jenereta ya dizilo
- Gwiritsani ntchito mphira wothamanga kwambiri kuti mupatule chipangizocho. Gawo ili laukadaulo tsopano ndi lokhwima kwambiri. Pambuyo kudzipatula mankhwala, kugwedera pamwamba pa unit ndi bwino olekanitsidwa.
(2) Chitani njira yochepetsera phokoso pa njira yofalitsira, ndikuyika zolumikizira zofewa zothira mpweya pa chitoliro chotulutsa mpweya cha jenereta kuti muchepetse kuwala kwakunja kwa gwero la mawu. Malinga ndi mfundo yothira mpweya, kapangidwe ka chothira mpweya kangagwiritse ntchito chothira mpweya choletsa. Chimagwiritsa ntchito zinthu zoboola mawu - thovu la melamine, lomwe limakonzedwa mwanjira inayake mu chitolirocho. Mpweya ukadutsa mu chothira mpweya choletsa mpweya, mafunde a mawu amachititsa kugwedezeka mumlengalenga ndi ulusi waung'ono m'mabowo a thovu la melamine . Chifukwa cha kukangana ndi kukana kokhuthala, mphamvu ya mawu imasandulika mphamvu ya kutentha ndikuyamwa, motero imachita ngati choletsa.
(3) Khoma lililonse la chipindacho limapangidwa ndi zigawo zingapo za zinthu zochepetsera phokoso, kuphatikiza ubweya wa miyala, nsalu za mauna omveka bwino komanso bolodi lotengera mawu. Kuonjezera khoma lotulutsa phokoso pakhoma la chipinda cha jenereta mkati mwa chipinda cha makina sikungangochepetsa phokoso la reverberation mu chipinda cha makina pamene kumapangitsa kuti phokoso likhale lopanda phokoso, komanso kuchepetsa kufalikira kwa phokoso lamphamvu pamene likuthamangira pamwamba.
(4) Popanga polowera mpweya ndi kutulutsa mpweya, milingo yocheperako yolowera mpweya ndi voliyumu yofunikira kuti igwire bwino ntchito yagawo imaganiziridwa bwino. Panthawi imodzimodziyo, kuti athetse vuto la kutentha kwa kutentha mu chipinda cha makina, mpweya wolowera mpweya ndi kutulutsa mpweya wa jenereta uyenera kukhazikitsidwa pamzere wowongoka womwewo. Kuonjezera apo, mpweya wolowera ndi mpweya uyenera kukhala ndi ma grilles oletsa kutulutsa mawu.
3.Conclusion
Phokoso lochokera ku makina opangira ma dizilo obowola mafuta ndiye gwero lalikulu kwambiri laphokoso pamalo onse pobowola. Zimakhudza kwambiri chitetezo cha chilengedwe ndipo sizikugwirizana ndi zofunikira za chitetezo ndi chilengedwe (HSE), choncho ziyenera kupewedwa. Nkhaniyi ikuchita kafukufuku wa phokoso lopangidwa ndi seti ya jenereta ya dizilo, ndipo imapereka njira zopangira zochepetsera phokoso mu chipinda chosungiramo ma jenereta, zomwe zingapereke chidziwitso kwa ogwira ntchito.
