Matanho ekuderedza ruzha muPerkins Jenareta Kamuri

Tisati tadzikisa ruzha rwedhiziri jenareta seti, isu tinofanirwa kuziva zvakajeka kunobva ruzha.

1.Noise source analysis ye diesel generator set

A. Diesel jenareta seti ruzha manyuko akaoma kunzwisisa anoumbwa nemanyuko akawanda enzwi.Zvinoenderana nemaitiro eruzha radiation, inogona kukamurwa kuita aerodynamic ruzha, pamusoro pemwaranzi ruzha uye electromagnetic ruzha.Zvinoenderana nezvikonzero, ruzha rwemwaranzi yedhiziri inogona kukamurwa kuita ruzha rwekupisa uye ruzha rwemuchina.Aerodynamic ruzha ndiyo huru ruzha sosi.

B. Ruzha rweAerodynamic runokonzerwa nekusagadzikana kwegasi, ndiko kuti, kuvhiringidzika kwegesi uye kupindirana pakati pegesi uye chinhu.Ruzha rweAerodynamic runopenya zvakananga kumhepo, kusanganisira ruzha rwekudya, ruzha rwemhepo uye kutonhora kwe fan.

C. Zvakaoma kunyatsosiyanisa pakati peruzha rwekupisa uye ruzha rwemagetsi.Kazhinji, ruzha runovhenekerwa nekudzvinyirirwa kunoitwa nekupisa mucylinder kuburikidza nemusoro wecylinder, piston, crankshaft uye muviri weinjini inodaidzwa kuti combustion ruzha.Ruzha rwunogadzirwa nekukanganisa kwepiston pane cylinder liner uye iyo mechanic inokanganisa vibration yezvikamu zvinofamba inonzi mechanical ruzha.Kazhinji, ruzha rwekupisa kweinjini yedhiziri yakananga yakakwira kupfuura ruzha rwemuchina, ukuwo ruzha rwemuchina weasina kunanga jekiseni injini yedhiziri yakakwirira kupfuura ruzha rwekupisa.Nekudaro, ruzha rwekupisa rwakakwira kupfuura ruzha rwemuchina pane yakaderera kumhanya.

E. Electromagnetic noise inogadzirwa nekumhanya-mhanya kwejenareta rotor munzvimbo yemagetsi.

Kune yakavhurika mhando dhiziri generator set, inoiswa mukati.Genset room inoda kuderedza ruzha.Iko kuderedzwa kweruzha kwekamuri yemuchina kunoda kubata nezvinokonzeresa ruzha zvakateerana, kunyanya kusanganisira nzira dzinotevera:

1. Kuderedzwa kweruzha rwemhepo inopinza uye kupera: iyo mhepo inopinza uye inopedza nzira yekamuri yemuchina inogadzirwa mumadziro ekudzivirira anonzwika zvichiteerana, uye mashizha ekunyarara anogadzwa mumhepo inopinza uye yekupedza nzira.Pane imwe chinhambwe muchiteshi chebhafa, kuitira kuderedza kusimba kwemwaranzi inonzwika kubva mukamuri yemuchina kuenda kunze.

2. Kudzora kwemutsindo wemuchina: kunyura kwemutsindo uye kuvharidzira zvinhu zvine ruzha kunyudza coefficient zvakaiswa pamusoro uye madziro akatenderedza ekamuri yemuchina, ayo anonyanya kushandiswa kubvisa kudzokorodza kwemukati uye kuderedza kusimba kwesimba rekurira uye kusimba kwekuratidzira mumushini. room.Kuti udzivise ruzha kubva kunze negedhi, isa moto inzwi rekudzivirira resimbi gonhi.

3. Kudzora kwehutsi hwehutsi hwehutsi: hutsi hwehutsi hunogadziriswa hune chidimbu chechipiri chinyararire pahwaro hwepakutanga yekutanga silencer, iyo inogona kuve nechokwadi chekutonga kunobudirira kwehutsi hunobudisa ruzha rwechikwata.Kana kureba kwepombi yekupedza utsi ichipfuura 10m, iyo dhayamita yepombi ichawedzerwa kuderedza kupera kwemashure kumanikidzwa kwejenareta.Iyo iri pamusoro kurapwa inogona kuvandudza ruzha uye kumashure kumanikidzwa kwejenareta seti.Kuburikidza nekurapa kwekudzikisa ruzha, ruzha rwejenareta yakaiswa mukamuri yemuchina inogona kusangana nezvinodiwa nevashandisi kunze.

Kuderedza ruzha rwekamuri yegenset kazhinji kunoda kuti pane nzvimbo yakakwana mukamuri yemuchina.Kana mushandisi asingakwanisi kupa imba yemuchina ine nzvimbo yakakwana, mhedzisiro yekudzikisa ruzha ichakanganiswa zvakanyanya.Haikwanise kudzora ruzha chete, asiwo kuita kuti jenareta isashande zvakajairika.Naizvozvo, mhepo inlet chiteshi, exhaust chiteshi uye nzvimbo yekushanda yevashandi inofanirwa kuiswa mukamuri yemuchina.

Tinokurudzira kuti mushure mekuderedza ruzha, iyo dhiziri genset inoda kushanda pasi pemutoro wenhema kugadzirisa iyo chaiyo simba redhiziri generator set (simba reinjini yemafuta richaderera mushure mekudzikisa ruzha) kuderedza uye kudzivirira njodzi uye kugadzirisa kuchengetedza chinhu.
