Zingaphi Iindidi zeJenereyitha yesiXhomlisi

Ngokubhekiselele kwiijenereyitha, izithulisi zinokunciphisa ingxolo kunye nokukhutshwa kombhobho ngexesha lokutsha kanye njengeenjini ezisetyenziselwa usetyenziso lweemoto kunye nolwakhiwo.

1. Zintathu uyilo olusisiseko izithulisi zejenereyitha :

Isithulisi sokufunxa isandi.Ulwakhiwo lwangaphakathi luqulunqwe ngefiber yeglasi okanye iglasi ekhuselayo.Emva kokuba i-exhaust idlule kwi-insulation, ingxolo yayo iya kuncitshiswa.Le ndlela isetyenziselwa ukunciphisa amaza esandi aphezulu.

Isithulisi esidibeneyo.Ukudibanisa i-react silencer kunye ne-absorption silencer, imathiriyeli yokufunxa ifakwe kuyilo lwangaphakathi lwe-reaction silencer, ngaloo ndlela kuncitshiswa lonke uyilo lwamaza.

Isithulisi esisebenzayo.Ulwakhiwo lwangaphakathi lunemingxuma emithathu edityaniswe ngamabhubhu.Ingxolo yokukhupha phakathi kwamagumbi okukhupha iphinda ibuyele, inciphisa ingxolo ephumayo yokunciphisa ingxolo ephakathi kunye nephantsi.

2. Isithulisi seCylindrical

I-Cylindrical muffler yenye yeemilo zokuqala eziphuhlisiwe.Zinokwakhiwa kuzo zontathu ziyilo ezisisiseko kwaye zinokusetyenziswa ngaphakathi nangaphandle.Izithulisi zinokufakelwa ngokuthe tye okanye ngokuthe nkqo ngokweemfuno zezicelo ezahlukeneyo.Kuthiwa esi sesinye sezithulisi ezinoqoqosho.

3. Isithulisi esibhityileyo

I-muffler ingaba noxande, i-oval, i-circular kunye nezinye iimilo.Ubume obukhethiweyo buxhomekeke kwindawo ekhoyo.Bahlala besebenzisa iijenereyitha kwiindawo ezivalelekileyo zokuthomalalisa isandi.Izixhobo zokubulala iintsholongwane kufuneka zihambelane nemigaqo yeNational Fire Protection Association (NFPA).

Xa i-generator isebenza kwindawo enokutsha, inkqubo yokukhupha kufuneka iguqulwe ukuze kuqinisekiswe ukuba iintlantsi ezenziwe kwinkqubo yokutsha aziyi kukhutshwa emoyeni.Izithulisi ze-Mars brake zihlala zisilinda kwaye zisebenzisa uyilo oluphuculweyo lwereactor.Ngale ndlela, i-carbon spark ijikeleza kwi-muffler kwaye iwela kwibhokisi yokuqokelela.Ngexesha lokugcinwa, ibhokisi yokuqokelela kufuneka icocwe.

Ubushushu bombhobho wokukhupha bufikelela kwi-1400 degrees Fahrenheit.Le gesi isoloko ikhutshelwa emoyeni.Isithulisi somoya oshushu sisetyenziselwa ukusebenzisa ubushushu kwirhasi yokuphuma emva koko singene emoyeni.Lo mthombo wobushushu unokusetyenziswa kuyo nayiphi na inkqubo efuna umthombo wobushushu wangaphandle.Nceda ubone iimpawu zokukhupha kunye nejika lobushushu.

4.Exhaust control silencer

Kukho iintlobo ezininzi zeegesi ezinokutsha.Ezinye iigesi ziyingozi kakhulu, ezinye aziyongozi.I-Arhente yeSizwe yoKhuseleko lokuSingqongileyo (i-EPA) inyanzelisa imimiselo yegesi yenkunkuma ukunciphisa ukukhutshwa kwegesi eyingozi.

I-State Environmental Protection Administration ilawula ngokungqongqo ukukhutshwa kwe iijenereyitha ezibonelela ngamandla amakhulu.Imimiselo yangoku echaphazelekayo ifuna ukusetyenziswa kwe-catalytic converters.Isiguquli esisisiseko senziwe kwigridi yeselula kwaye ifakwe ngokuthe ngqo kwinkqubo yokukhupha emva kombhobho wokukhupha.Kule ndawo, igesi yokukhupha igesi inokufikelela kubushushu obuphezulu obufunekayo ekusebenzeni okuqhelekileyo.Izithulisi ezininzi ezitsha zisebenzisa indibaniselwano yeziguquli kunye nezithulisi.

Izibonelelo ezichaphazelekayo zikwabhekiselele kumxholo we-particulate matter kwi-exhaust gas.Umxholo wesoot werhasi yokukhupha unokuncitshiswa ngokusebenzisa isihluzo se-particulate.Uluhlu lwangaphakathi lwesikrini lokucoca lwenziwe ngezinto ze-ceramic.Igesi yokukhupha iqokelelwa ngezinto eziphathekayo kunye ne-soot.Ii-injini zokutshisa ezibhityileyo zinokusebenzisa izongezo ukunciphisa ngakumbi ukukhutshwa kwerhasi eyingozi.

Inqanaba lengxolo yesithulisi

Ubukhulu besandi obukhutshwa ngumbhobho wokuphuma bulinganiswa ngeedecibels.I-Decibel yiyunithi yomlinganiselo osetyenziswa ukumela umlinganiselo weempawu ezibonakalayo kwesinye isikali se-logarithmic.Ixabiso le-Decibel yindlela yokulinganisa efana nempendulo yendlebe yomntu kwisandi.

Izithulisi zakwangoko zahlulwa zaba ngamabanga amane asisiseko.Amanqanaba emizi-mveliso, ezorhwebo, eendawo zokuhlala kunye nezibhedlele athathwa njengemigangatho yoshishino yokuveliswa kwezithulisi.Ngexesha elifanayo, iziphumo zokunciphisa isandi zabavelisi abahlukeneyo nazo zihluke.I-Generation Systems Association (EGSA) iphuhlise uluhlu lwezikhokelo zokulinganisa ukubonelela ngomlinganiselo odibeneyo we-muffler kubo bonke abavelisi abakumbutho.Kuye kwaba ngumgangatho woshishino lwemveliso.

Amanqanaba aqhelekileyo ngala:

Ibakala lemizi-mveliso - ukunciphisa ingxolo nge-15 ukuya kwi-20 dB.

Umgangatho wezindlu - nciphisa ingxolo yokukhupha nge-20 ukuya kwi-25 dB.

Inqanaba elibalulekileyo - ukukhupha ingxolo yokunciphisa i-25-32 dB.

Ixabiso elibaluleke kakhulu - ukunciphisa ingxolo nge-30-38 dB.

Inqanaba lezonyango - ukunciphisa ingxolo yokukhupha nge-35-42 dB.

Inqanaba elongezelelweyo esibhedlele - ukunciphisa ingxolo yokukhupha nge-35-50 dB.

Inqanaba lokunciphisa - ukunciphisa ingxolo nge-40-55 dB.

Inqanaba elingaphezulu komda - nciphisa ingxolo ngama-45-60 dB.

Kufuneka kuqatshelwe ukuba ayizizo zonke izithuli kunye nesimbo ezinokusebenza kuwo onke amanqanaba.Abavelisi abahlukeneyo bavelisa iimodeli ezahlukeneyo, kwaye iindleko zabo zokuvelisa kunye neempawu ezibonakalayo ze-silencers zigqiba inqanaba lokufumaneka.
