1. Mhando dzeNoise
· Mechanical ruzhamhedzisiro kubva muzvikamu zvinofamba mukati mejenareta seti: friction, vibration, uye kukanganisa kana unit iri kushanda.
· Aerodynamic ruzhainomuka kubva mukuyerera kwemhepo - kana kuyerera kuine mhirizhonga, kusingaenzaniswi muhuwandu uye amplitude, inogadzira ruzha rwebroadband.
· Electromagnetic ruzhainogadzirwa nekudyidzana kwemuchina unotenderera magineti emhepo-gap uye iyo stator iron core. Harmonics mumhepo-gap inokonzeresa periodic magetsi emagetsi, inotungamira kune radial deformation yeiyo stator musimboti uye nekudaro ruzha runopenya.
2. Key Noise-Kudzora Matanho
Nzira huru dzekudzikisa ruzha ndeidzi: kunyudzwa kweruzha, kuvharira ruzha, kuzunguzika kwega (kana kunyorovesa), uye kudzora ruzha.
· Kutorwa kwenzwi:Shandisa porous zvinhu kutora simba rezwi. Nepo mapaneru akatetepa (akadai seplywood kana iron mahwendefa) anogona zvakare kutora yakaderera-frequency ruzha, kuita kwavo kunowanzo kushomeka. Semuyenzaniso, kurongedza mahwendefa maviri esimbi ehukobvu hwakafanana chete kunonatsiridza kuvharirwa kwenzwi ne6 dB - saka sarudzo yemidziyo uye kumisikidzwa kwakakosha.
· Inzwi rekudzivirira:Kugona kwechinhu / sisitimu yekuvhara ruzha kunoenderana zvakanyanya nehukuru hwayo density. Asi kungo wedzera matunhu hakushande - mainjiniya anowanzo ongorora musanganiswa wezvinhu zvisingaremi kuti uvandudze insulation zvakanyanya.
· Vibration yekuzviparadzanisa nevamwe uye kuderedza:Majenareta seti anowanzo fambisa ruzha kuburikidza nechimiro chinotakurwa vibration. Metal springs inoshanda zvakanaka muzasi-kusvika-pakati-frequency range; mapedhi erubha ari nani kune akakwira ma frequency. Kusanganiswa kwezvose zviri zviviri kwakajairika. Damping zvinhu zvinoshandiswa panzvimbo inoderedza vibration amplitudes uye nekudaro inodzikisa ruzha radiation.
· Active noise control (ANC):Iyi tekinoroji inobata chiratidzo cheruzha sosi uye inogadzira yakaenzana-amplitude, yakatarisana-chikamu chinonzwika wave kudzima ruzha rwekutanga.
3. Kunyanya Kutarisa: Exhaust Silencer & Airflow Noise
Chinhu chakakosha cheruzha mune dizeli generator set room ndiko kupera simba. Silencer (kana muffler) yakaiswa padivi penzira yekupopota inoshanda nekumanikidza kurira kweinzwi kuti iwirirane nemukati memukati mesilencer kana kuzadza zvinhu, ichishandura simba rekurira kuita kupisa (uye nekudaro kuridzivirira kupararira).
Kune marudzi akasiyana-siyana emanyaradzi - anopikisa, anoshanda, uye impedance-yakasanganiswa. Kuita kweanodzivirira silencer kunoenderana nekumhanya kwekuyerera, kuyambuka-chikamu nzvimbo, kureba, uye kunyudza coefficient yekuzadza zvinhu.
4. Jenereta Set Room Acoustic Treatment
Kushanda acoustic kurapwa kwejenareta seti yekamuri zvakare kunosanganisira kurapa madziro, sirin'i, pasi, magonhi uye nzira dzekufema nemhepo:
· Madziro/masirin’i/pasi:Shandisa musanganiswa we-high-density insulation (yekudzivirira inzwi) uye porous absorbent materials (yekunzwa inzwi). Semuyenzaniso, insulating zvinhu zvakaita sedombo wool, mineral wool, polymer composites inogona kushandiswa; pakunyura, zvinhu zvine porous sefuro, polyester faibha, makushe kana fluorocarbon mapolima.
· Masuo:Yakajairwa kuisirwa imba yejenareta yaizove negonhi rimwe rakakura uye rimwe diki redivi remusuwo - yakazara gonhi nzvimbo haifanire kudarika 3 m². Chimiro chacho chinofanira kunge chiri chesimbi-chakaumbwa, chakaiswa mukati nepamusoro-chinoita ruzha-insulation material, uye chakashongedzerwa zvisimbiso zverabha zvakatenderedza furemu kuti ive nechokwadi chekusimba uye kuderedza kubuda kwekurira.
· Kufefetedza / kuyerera kwemhepo:Iyo jenareta seti inoda mweya wakakwana wekupisa nekutonhodza, saka iyo nyowani-yemhepo inopinza inofanirwa kutarisana neyakanakira fan yekuburitsa. Mukuisa kwakawanda dhizaini yekumanikidza-mhepo yekupinda inoshandiswa: mhepo yekupinda inopfuura nepamhepo inonyararidza-inokwevera mukamuri neinofuridza. Panguva imwe chete, kupisa kweradiator uye kubuda kwemhepo kunofanirwa kuburitswa kunze, kuburikidza nekunyarara plenum kana duct. Semuyenzaniso, exhaust inopfuura nemugero rekunyararidza rakavakwa nechekunze rakatenderedza silencer, kazhinji rine madziro ekunze ezvidhinha uye mukati memukati anonwisa mapaneru. Iyo pombi yekupedza simba inogona kuputirwa nemoto-proof dombo-wool insulation, izvo zvese zvinoderedza kupisa kwemukati mukamuri uye zvinocheka ruzha rwekudengenyeka.
5. Nei Izvi Zvichikosha
Jenareta redhiziri riri kushanda rinogona kuburitsa ruzha rwemukati muhurongwa hwe105-108 dB (A). Pasina chero kudzikamisa ruzha, iyo yekunze ruzha - kunze kwekamuri - inogona kusvika 70-80 dB (A) kana kutokwira. Maseti ejenareta emumba (kunyanya asiri eprimiyamu mabhureki) anogona kunge akatonyanya ruzha.
MuChina, kutevedzera mitemo yemheremhere yemunharaunda kwakakosha. Semuyenzaniso:
· Mumadhorobha “Kirasi I” nzvimbo (dzinowanzogara), muganho wemasikati uri 55 dB(A), uye nguva yehusiku i45 dB(A).
Munzvimbo dzepasi peguta "Kirasi II", muganho wemasikati i60 dB (A), nguva yehusiku 50 dB (A).
Nekudaro, kushandisa nzira dzekudzora ruzha dzakatsanangurwa hazvisi zvekunyaradza chete - zvinogona kudikanwa pakutevedzwa kwemitemo paunenge uchiisa jenareta munzvimbo dzakavakwa kana pedyo.
Kana uri kuronga kuisa kana kushandisa jenareta redhiziri rakaiswa munzvimbo isinganzwi ruzha, unofanira kutarisana nedambudziko zvakazara: sarudza yakaringana yekuvharisa uye yekunyudza zvinhu, yega uye yakanyorovesa vibrations, nyatso gadzira mhepo yemukamuri uye nzira yekuburitsa (kusanganisira silencers), uye kana zvichidikanwa, funga nezve inoshanda kudzora ruzha mhinduro. Kuwana zvese izvi zvinhu zvakanaka kunogona kuita mutsauko pakati pekuteedzera, hunhu hwekumisikidza uye kunetsa (kana kutyora mutemo).
AGG: Yakavimbika Jenareta Seti Mupi
Sekambani yenyika dzakawanda yakatarisana nekugadzira, kugadzira uye kugovera masisitimu ekugadzira magetsi uye mhinduro dzesimba repamusoro, AGG inopa mhinduro dzakagadzirwa kune dzakasiyana siyana dzekushandisa.
Zvikwata zvehunyanzvi zveinjiniya zveAGG zvinogona kupa mhinduro dzemhando yepamusoro uye masevhisi ayo ese anosangana nezvinodiwa zvevatengi vakasiyana uye musika wakakosha, uye masevhisi akagadziridzwa. AGG inogona zvakare kupa dzidziso inodiwa yekuisa, kushanda uye kugadzirisa.
Iwe unogona kugara uchivimba neAGG kuti ive nechokwadi chehunyanzvi hwayo hwakabatanidzwa sevhisi kubva pakugadzira purojekiti kusvika pakuita, iyo inovimbisa kugara kwakachengeteka uye kwakagadzikana kushanda kwechiteshi chemagetsi.
