Noise Reduction Kurapa kweJenareta Kamuri

Kana jenareta redhiziri richimhanya, rinowanzo gadzira 95 ~ 128dB (A) ruzha.Kana zvichidikanwa matanho ekuderedza ruzha asina kutorwa, ruzha rwekushanda kwegenset huchakonzera kukuvadza kwakakomba kune zvakatenderedza.Kuti uchengetedze uye uvandudze kunaka kwezvakatipoteredza, ruzha runofanira kudzorwa.

Iwo makuru eruzha masosi edhiziri jenareta seti anogadzirwa neinjini yedhiziri, kusanganisira ruzha rwekupedza simba, ruzha rwemagetsi uye ruzha rwekupisa, kutonhora fan uye ruzha rwekupedza simba, ruzha rwekupinda, ruzha rwejenareta, ruzha rwunogadzirwa nekufambiswa kwenheyo vibration, nezvimwe.

(1) Kupera simba.Exhaust noise imhando yekupuruzira kuyerera kwemhepo ine tembiricha yepamusoro uye kumhanya kwakanyanya.Ndiro simba rakawanda muruzha rweinjini.Ruzha rwayo runogona kusvika kupfuura 100dB.Ndiyo inonyanya kukosha chikamu chese injini ruzha.Ruzha rwe exhaust rwakagadzirwa panguva yekushanda kwe jenareta inobudiswa zvakananga kuburikidza nepombi yakapfava yakapfava (pombi yepakutanga yekuburitsa yejenareta set), uye ruzha rweruzha runowedzera zvakanyanya nekuwedzera kwekumhanya kwemhepo, iyo ine kukanganisa kwakakomba pahupenyu nebasa revagari vepedyo.

(2) Mechanical ruzha uye ruzha rwekupisa.Mutsindo weMechanical unonyanya kukonzerwa nekuzunguzika kana kuwirirana kwezvikamu zvinofamba zveinjini zvichikonzerwa nekuchinja nguva nenguva kwegasi kudzvanywa uye kufambisa inertia simba panguva yekushanda.Iyo ine hunhu hwekurebesa ruzha kuparadzira uye kuderedzwa attenuation.Combustion ruzha ndiko kuzunguzika kwechimiro uye ruzha runogadzirwa nedhiziri panguva yekupisa.

(3) Kutonhodza feni uye nekupedza ruzha.Ruzha rwe fan yeyuniti inoumbwa ne eddy yazvino ruzha, inotenderera ruzha uye mechanic ruzha.Exhaust ruzha, ruzha rwekuyerera kwemhepo, ruzha rwe fan uye ruzha rwemuchina zvichafambiswa kuburikidza nemugero wekuburitsa, zvichikonzera kusvibiswa kweruzha kunharaunda.

(4) Ruzha runouya.Basa reiyo air inlet chiteshi ndere kuve nechokwadi chekushanda kwakajairika kweinjini uye kugadzira yakanaka kupisa kupisa mamiriro eiyo unit pachayo.Iyo mhepo inopinza chiteshi cheyuniti inofanirwa kugonesa iyo inopinza mhepo kupinda mukamuri yemuchina zvakanaka, asi panguva imwecheteyo, ruzha rwemuchina uye ruzha rwekuyerera kwemhepo yeyuniti inozovhenekerwa kunze kwekamuri yemuchina kuburikidza neiyi mhepo inopinza chiteshi.

(5) Kutumira ruzha rwenheyo vibration.Iyo yakasimba mechaniki vibration yeinjini yedhiziri inogona kuendeswa kunzvimbo dzekunze kuburikidza nenheyo, uye yobva yaburitsa ruzha pasi.

Iyo musimboti wekudzikisa ruzha kurapwa mukamuri yedhiziri generator ndeye kushandisa zvinotora ruzha zvinhu uye kuderedza ruzha uye kunyararidza midziyo kuderedza ruzha rwemhepo inopinza uye nzira dzekupedza simba uye exhaust system pachinzvimbo chekuona mamiriro ekufema kwedhiziri jenareta seti. iri, pasina kudzikisa simba rekubuda, kuitira kuti ruzha rwekubuda risangane nechiyero chenyika 85dB (A).

Iyo inonyanya kukosha nzira yekudzikisa ruzha rwejenareta ndeyekutanga kubva kune inonzwika sosi uye kutora mamwe akajairwa ekuderedza ruzha matekinoroji;Semuyenzaniso, muffler, kuvharwa kwenzwi, kupfekwa kwenzwi uye kuzviparadzanisa nevamwe ndiyo nzira dzinoshanda.

(1) Deredza ruzha rwekupera simba.Exhaust noise ndiyo huru ruzha sosi yeyuniti, iyo inoratidzirwa nepamusoro ruzha mwero, kukurumidza kupera simba uye kuoma kukuru mukurapa.Ruzha rwekupedza simba runogona kuderedzwa ne40-60dB (A) nekushandisa yakakosha impedance composite muffler.

(2) Deredza ruzha rweaxial flow fan.Paunenge uchidzikisa ruzha rwekutonhora fan yejenareta seti, matambudziko maviri anofanirwa kutariswa: imwe ndiyo inobvumidzwa yekumanikidza kurasikirwa kwechiteshi chekuburitsa.Chechipiri ndiyo mari inodiwa yekunyarara.Pamapoinzi maviri ari pamusoro, resistive chip muffler inogona kusarudzwa.

(3) Inzwi rekudzivirira uye kunyura kurapwa kwekamuri yemuchina uye vibration kuparadzaniswa kwedhiziri jenareta.

1) Inzwi rekudzivirira kwekamuri yemuchina.Mushure meruzha rwekupedza simba uye kutonhora kwe fan ruzha rwedhiziri genset yadzikiswa, akasara makuru eruzha masosi dizeli enjini mechanicha ruzha uye ruzha rwekupisa.Kunze kwehwindo rinodiwa remukati rekutarisa hwindo rakabatana nekamuri yekutarisa, mamwe ese mahwindo achabviswa, maburi ese nemaburi achavharwa zvakasimba, uye ruzha rwekuvharidzira kwemadziro ezvidhina ruchapfuura 40dB (a).Magonhi nemahwindo ekamuri yemuchina haapinde moto uye magonhi nemahwindo ekudzivirira anonzwika.

2) Air inlet uye kupera.Mushure meiyo ruzha rwekudzivirira kurapwa kwekamuri yemuchina, dambudziko rekufefetedza uye kupisa kupisa mukamuri yemuchina rinogadziriswa.Mhepo inopinza ichaiswa mumutsara wakatwasuka nejenareta seti uye yekuburitsa.Iyo inopinza mhepo ichave yakashongedzerwa neresisive chip muffler.Sezvo kurasikirwa kwekumanikidzwa kwemhepo inopinza zvakare mukati meiyo inotenderwa renji, iyo mhepo yekupinza uye yekubuda mukamuri yemuchina inogona kuve yakaenzana, uye kufefetedza uye kupisa kupisa mhedzisiro iri pachena.

3) Inzwi rekubata kurapwa.Iwo madziro mashanu ari mukamuri yemuchina kunze kwepasi anogona kurapwa kunyudzwa kwekurira, uye iyo perforated ndiro resonance ruzha inotorwa chimiro inogamuchirwa zvinoenderana neiyo frequency spectrum maitiro ejenareta seti.

4) Kutsinhana kwemhepo yemukati uye yakanaka inonzwika yekuvharira kwekamuri yemuchina inodzivirira mweya uri mukamuri yemuchina kubva pakutenderera kana yakavharwa mvura-yakatonhorera jenareta unit yakavharwa, uye tembiricha yepamusoro mukamuri haigone kudzikiswa mukati. nguva.Dambudziko rinogona kugadziriswa nekushandisa yakaderera-ruzha axial kuyerera fan uye resistive plate muffler.

5) Vibration kuparadzaniswa kweyuniti.Pamberi pekugadzwa kwe jenareta remagetsi , iyo vibration yekuzviparadzanisa kurapwa ichaitwa zvakanyatsoenderana neakakodzera data rakapihwa nemugadziri kudzivirira kureba-kure kufambisa kwechimiro chechimiro, uye ruzha rwemhepo rucharamba ruchivhenekerwa mukufambiswa, kuitira kuti ruzha padanho. muganhu wechirimwa haugone kusangana nechiyero.Kune iyo iripo jenareta seti inoda kurapwa nekuda kwekupfuura mwero, kutedera kwepasi pedyo neyuniti kunofanirwa kuyerwa.Kana manzwiro ekudengenyeka ari pachena, jenareta seti inofanira kuparadzaniswa kutanga.

Mushure mekunyatso dzikisa ruzha, kuitira kuti mamiriro emukamuri yemuchina awedzere kunaka uye anoshanda, iyo inonzwika-inotora madziro emadziro uye sirin'i kazhinji yakashongedzwa ne microporous aluminium-plastic perforated plate, uye iyo yekuvhenekesa system inogadziriswa zvine musoro.
