Kana dhiziri seti yejenareta iri kushanda, inowanzo buritsa 95-110db (a) ruzha, uye ruzha rwejenareta redhiziri rinogadzirwa panguva yekushanda huchakonzera kukanganisa kwakakomba kunharaunda yakapoteredza.
Noise source analysis
Ruzha rwedhiziri jenareta seti inzwi rakaomarara sosi rinoumbwa nemhando dzakawanda dzemanzwi. Zvinoenderana nenzira yeruzha radiation, inogona kukamurwa kuita aerodynamic ruzha, pamusoro nemwaranzi ruzha uye electromagnetic ruzha. Zvinoenderana nechikonzero, iyo dhiziri jenareta yakaiswa pamusoro pemwaranzi ruzha inogona kukamurwa kuita ruzha rwekupisa uye ruzha rwemagetsi. Aerodynamic ruzha ndiyo huru ruzha sosi yedhiziri jenareta ruzha.
1. Ruzha rweAerodynamic runokonzerwa nekusagadzikana kwegasi, kureva, dhiziri generator ruzha rwakakonzerwa nekuvhiringidzika kwegesi uye kuwirirana pakati pegesi nezvinhu. Ruzha rweAerodynamic rwakananga mumhepo, kusanganisira ruzha rwekudya, ruzha rwekupedza simba uye kutonhora kwe fan.
2. Electromagnetic ruzha idhiziri jenareta seti ruzha runogadzirwa nejenareta rotor inotenderera nekumhanya kwakanyanya mumunda wemagetsi.
3. Kupisa ruzha uye ruzha rwemagetsi rwakaoma kunyatsosiyanisa, kazhinji nekuda kwe diesel jenareta cylinder combustion inokonzerwa nekumanikidza kushanduka kuburikidza nemusoro wecylinder, piston, coupling, crankshaft, muviri unopenya kunze kwejenereta seti ruzha rwunonzi ruzha rwekupisa. Iyo jenareta yakaseta ruzha rwunokonzerwa nekukanganisa kwepiston pacylinder liner uye iyo mechanic inokanganisa vibration yezvikamu zvinofamba inonzi mechanical ruzha. Kazhinji, ruzha rwekupisa rweinjini yedhiziri yakananga yakakwira kupfuura ruzha rwemuchina, uye ruzha rwemuchina weisina-yakananga jekiseni injini yedhiziri yakakwirira kupfuura ruzha rwekupisa. Nekudaro, ruzha rwekupisa rwakakwira kupfuura ruzha rwemuchina padiki kumhanya.
Regulatory measure
Diesel jenareta kudzora ruzha matanho
1: imba isina ruzha
Imba yekudzivirira inonzwika inoiswa munzvimbo yejenareta yedhiziri, saizi i8.0m×3.0m×3.5m, uye madziro ekunze ebhodhi rekudzivirira ruzha i1.2mm galvanized plate. Rusvingo rwemukati iplate ye 0.8mm perforated, yepakati yakazadzwa ne 32kg/m3 Ultra-fine glass wool, uye rutivi rwe concave rwechiteshi simbi yakazadzwa negirazi makushe.
Diesel jenareta ruzha kutonga matanho maviri: kupera ruzha kuderedza
Iyo jenareta yedhiziri inotsamira pane yayo fan kuti ipedze mhepo, uye iyo AES rectangular muffler inoiswa pamberi peimba yekupopota. Muffler saizi ndeye 1.2m×1.1m×0.9m. Iyo muffler yakashongedzerwa nehukobvu hwemuffler hwe200mm uye nzvimbo ye100mm. Silencer inotora chimiro cheultra-fine girazi wool yakasungirirwa nemarata ane galvanized perforated pamativi ese. Manyaradzi mapfumbamwe ehukuru hwakafanana akaunganidzwa kuita 1.2m×3.3m×2.7m hombe silencer. Exhaust louvers yehukuru hwakafanana inowanikwa 300mm pamberi pemuffler.
Diesel jenareta ruzha kutonga matanho matatu: air inlet ruzha kuderedza
Isa yakasikwa inlet muffler padenga rekudzivirira ruzha. Iyo muffler inogadzirwa neamwechete epoust air muffler, iyo mambure muffler kureba ndeye 1.0m, saizi ye-cross-section ndeye 3.4m×2.0m, iyo muffler sheet iri 200mm gobvu, nzvimbo yacho 200mm, uye muffler yakabatana ne isina mutsetse 90° muffler gokora, uye muffler gokora rakareba 1.2m.
Diesel jenareta ruzha kutonga zviyero zvina: exhaust ruzha
Kuburikidza nejenareta yedhiziri seti yepakutanga inofananidzira mamuffler ekugara kuti abvise ruzha, ruzha mushure mehutsi hwasanganiswa kuita Φ450mm yehutsi pombi kubva pavhavha yekuburitsa kubuda kumusoro.
Diesel jenareta ruzha kutonga matanho mashanu: static speaker (yakaderera ruzha)
Isa dhiziri jenareta seti inogadzirwa nemugadziri mubhokisi reruzha rakaderera, rinogona kuderedza ruzha uye kudzivirira mvura.
Low ruzha mukana
1. Chinja kune zvinodiwa zvekuchengetedzwa kwenzvimbo yemaguta, ruzha rwakaderera panguva yekushanda;
2. Ruzha rwezvikamu zvakajairika runogona kudzikiswa kusvika pa70db (A) (yakayerwa paL-P7m);
3. Ultra-low ruzha chikwata kusvika 68db (A) (L-P7m kuyerwa);
4. Iyo van type power station ine yakaderera-ruzha anti-sound chamber, yakanaka ventilation system uye matanho ekudzivirira kupisa kwemwaranzi inovimbisa kuti iyo unit inogara ichishanda pane yakakodzera ambient tembiricha.
5. Chimiro chepasi chinotora kaviri-layer dhizaini uye yakakura simba remafuta tangi, iyo inogona kuramba ichipa iyo unit kuti iite kwemaawa masere;
6. Matanho anobudirira ekunyorovesa anovimbisa kushanda kwakaenzana kwechikwata; Dzidziso yesainzi uye dhizaini yemunhu inoita kuti zvive nyore kuti vashandisi vashande uye vatarise mamiriro ekuita kweyuniti.
