Mitundu Yambiri Yama Jenereta Silencer

Ponena za majenereta, zotsekera zimatha kuchepetsa phokoso ndi mpweya wotulutsa mpweya pakuyaka monga momwe ma injini amagwiritsidwira ntchito pamagalimoto ndi zomangamanga.

1. Pali zinthu zitatu zofunika kupanga jenereta silencers :

Chotsekereza mawu.Mapangidwe amkati amapangidwa ndi galasi fiber kapena galasi lotsekera.Pambuyo potulutsa mpweya kudutsa muzitsulo, phokoso lake lidzachepetsedwa.Njirayi imagwiritsidwa ntchito pochepetsa mafunde amphamvu kwambiri.

Silencer yophatikizika.Kuphatikiza silencer reaction ndi silencer mayamwidwe, zinthu mayamwidwe anaika mkati kamangidwe ka silencer reaction, motero kuchepetsa mapangidwe pafupipafupi.

Reactive silencer.Kapangidwe kamkati kamakhala ndi mapanga atatu olumikizidwa ndi machubu.Phokoso lotulutsa mpweya pakati pa zipinda zotulutsa mpweya zimabwereranso, kuchepetsa phokoso lotulutsa kuti muchepetse phokoso lapakati komanso lotsika.

2. Cylindrical silencer

Cylindrical muffler ndi imodzi mwamawonekedwe akale kwambiri.Zitha kupangidwa m'mapangidwe onse atatu ndipo zingagwiritsidwe ntchito mkati ndi kunja.Ma silencer amatha kukhazikitsidwa molunjika kapena molunjika malinga ndi zofunikira zamapulogalamu osiyanasiyana.Akuti uyu ndi m'modzi mwa oletsa chuma chambiri.

3. Chotsekereza chocheperako

Chophimbacho chimatha kukhala ndi makona anayi, oval, ozungulira ndi ena.Mawonekedwe osankhidwa amadalira malo omwe alipo.Nthawi zambiri amagwiritsa ntchito ma jenereta m'malo otsekereza mawu.Zida zophera tizilombo zimayenera kutsatira malamulo a National Fire Protection Association (NFPA).

Pamene jenereta ikugwira ntchito m'malo oyaka moto, mpweya wotulutsa mpweya uyenera kusinthidwa kuti zitsimikizire kuti zowotcha zomwe zimapangidwira poyatsira sizidzatulutsidwa mumlengalenga.Mars brake silencer nthawi zambiri amakhala cylindrical ndipo amagwiritsa ntchito kamangidwe kabwino ka riyakitala.Mwanjira iyi, mpweya wa kaboni umazungulira mu muffler ndikugwera m'bokosi lotolera.Panthawi yokonza, bokosi losonkhanitsa liyenera kutsukidwa.

Kutentha kwa chitoliro cha chitoliro kumafikira madigiri 1400 Fahrenheit.Mpweya umenewu nthawi zambiri umatulutsidwa mumlengalenga.The hot air silencer imagwiritsidwa ntchito kutenthetsa mu mpweya wotuluka ndikulowa mumlengalenga.Gwero la kutenthali lingagwiritsidwe ntchito pa dongosolo lililonse lomwe likufuna kutentha kwakunja.Chonde onani mawonekedwe a utsi ndi kutentha kopindika.

4.Exhaust control silencer

Pali mitundu yambiri ya mpweya woyaka.Mipweya ina ndi yovulaza kwambiri, ina ilibe vuto.Bungwe la National Environmental Protection Agency (EPA) limakhazikitsa malamulo oyendetsera gasi kuti achepetse mpweya woipa.

State Environmental Protection Administration imayendetsa mosamalitsa kutulutsa kwa jenereta zomwe zimapereka mphamvu yayikulu.Malamulo omwe alipo pano amafunikira kugwiritsa ntchito ma catalytic converters.Chosinthira choyambirira chimapangidwa kuchokera ku gridi yama cell ndipo chimayikidwa mwachindunji mumayendedwe otulutsa kuseri kwa chitoliro chotulutsa.Pamalo awa, mpweya wotulutsa mpweya ukhoza kufika kutentha kwakukulu komwe kumafunika kuti ntchito yamba.Ma silencer ambiri atsopano amagwiritsa ntchito kuphatikiza kwa otembenuza ndi masilencer.

Zomwe zili zoyenera zikugwirizananso ndi zomwe zili muzinthu zamtundu wa gasi.Mwaye zomwe zili mu gasi wotulutsa zimatha kuchepetsedwa pogwiritsa ntchito fyuluta ya particulate.Wosanjikiza wamkati wa zosefera amapangidwa ndi zinthu za ceramic.Mpweya wotulutsa mpweya umasonkhanitsidwa ndi zipangizo ndi mwaye.Ma injini akuwotcha amathanso kugwiritsa ntchito zowonjezera kuti achepetse kutulutsa koyipa kwa gasi.

Phokoso la silencer

Kuchulukira kwa mawu otulutsa chitoliro kumayesedwa ndi ma decibel.Decibel ndi muyeso womwe umagwiritsidwa ntchito kuyimira chiŵerengero cha thupi limodzi ndi sikelo ina ya logarithmic.Mtengo wa decibel ndi njira yoyezera yofanana ndi kuyankha kwa khutu la munthu pomveka.

Zoletsa koyambirira zidagawidwa m'makalasi anayi oyambira.Mafakitale, malonda, malo okhala ndi zipatala amaonedwa ngati miyezo ya mafakitale popanga zoletsa.Panthawi imodzimodziyo, zotsatira zochepetsera zomveka za opanga osiyanasiyana zimakhalanso zosiyana.Bungwe la Generation Systems Association (EGSA) lapanga malangizo owongolera kuti apereke chiwongola dzanja chogwirizana kwa opanga onse omwe ali mgululi.Zakhala muyeso wamakampani opanga zinthu.

Miyezo yodziwika bwino ndi:

Gawo la mafakitale - kuchepetsa phokoso ndi 15 mpaka 20 dB.

Mulingo wanyumba - chepetsa phokoso la utsi ndi 20 mpaka 25 dB.

Mulingo wovuta - kuchepetsa phokoso la 25-32 dB.

Mtengo wovuta kwambiri - chepetsani phokoso ndi 30-38 dB.

Mulingo wamankhwala - chepetsa phokoso lotulutsa ndi 35-42 dB.

Mulingo wowonjezera wachipatala - chepetsani phokoso la utsi ndi 35-50 dB.

Mulingo wochepera - kuchepetsa phokoso ndi 40-55 dB.

Kupitilira malire - kuchepetsa phokoso ndi 45-60 dB.

Tiyenera kuzindikira kuti si silencer ndi kalembedwe kalikonse kangagwire ntchito pamagulu onse.Opanga osiyanasiyana amapanga mitundu yosiyanasiyana, ndipo mtengo wawo wopanga komanso mawonekedwe amtundu wa silencer zimatsimikizira kuchuluka kwa kupezeka.
