Ke Mefuta e Mengata ea li-Silencer tsa jenereithara

Mabapi le lijenereithara, li-silence li ka fokotsa lerata le mesi e tsoang nakong ea mollo joalo ka ha lienjine li sebelisoa lits'ebetsong tsa likoloi le tsa kaho.

1. Ho na le moralo oa motheo tse tharo li-silencers tsa jenereithara :

Sethusa-modumo sa ho monya.Sebopeho sa ka hare se entsoe ka fiber ea khalase kapa khalase ea insulating.Ka mor'a hore mokelikeli o fete ka ho kenya letsoho, lerata la eona le tla fokotseha.Mokhoa ona o sebelisoa ho fokotsa maqhubu a molumo o phahameng.

Sethulisi se kopantsoeng.Ho kopanya silencer ea karabelo le silencer ea absorption, thepa ea ho monya e kentsoe ka har'a moralo oa kahare oa sebui sa karabelo, ka hona, e fokotsa meralo eohle ea khafetsa.

Reactive silencer.Sebopeho sa ka hare se na le likoti tse tharo tse kopantsoeng ke li-tubes.Lerata la ho ntša metsi pakeng tsa likamore tsa ho ntša metsi le khutlela morao, le fokotsa lerata la tlhahiso ho fokotsa lerata le mahareng le le tlaase.

2. Cylindrical silencer

Cylindrical muffler ke e 'ngoe ea libopeho tsa khale ka ho fetisisa tse entsoeng.Li ka hahoa ka har'a meralo e meraro ea mantlha 'me li ka sebelisoa ka hare le ka ntle.Li-silencers li ka kenngoa ka holimo kapa ka holimo ho ea ka litlhoko tsa mefuta e fapaneng ea lisebelisoa.Ho boleloa hore ena ke e 'ngoe ea tse khutsitseng ka ho fetisisa moruong.

3. Setholisa se tšesaane

Moferefere o ka ba le libopeho tse khutlonnetsepa, oval, selikalikoe le tse ling.Sebopeho se khethiloeng se itšetlehile ka sebaka se fumanehang.Hangata ba sebelisa lijenereithara libakeng tse thibelang molumo.Thepa e bolaeang likokoana-hloko e tlameha ho lumellana le melaoana ea National Fire Protection Association (NFPA).

Ha jenereithara e sebetsa tikolohong e tukang, tsamaiso ea ho ntša metsi e tlameha ho fetoloa ho etsa bonnete ba hore litlhase tse hlahisoang ke ts'ebetso ea mollo li ke ke tsa ntšetsoa sepakapakeng.Li-silencer tsa Mars hangata li na le cylindrical 'me li sebelisa moralo o ntlafalitsoeng oa reactor.Ka tsela ena, tlhase ea carbon e potoloha ka har'a moferefere 'me e oela ka lebokoseng la pokello.Nakong ea tlhokomelo, lebokose la pokello le tlameha ho hloekisoa.

Mocheso oa phala ea ho ntša metsi o fihla ho likhato tse 1400 tsa Fahrenheit.Hangata khase ena e tšeloa sepakapakeng.Sethusa-moea se chesang se sebelisetsoa ho sebelisa mocheso ka har'a khase ea ho ntša metsi ebe se kena sepakapakeng.Mohloli ona oa mocheso o ka sebelisoa ho sistimi efe kapa efe e hlokang mohloli oa mocheso o kantle.Ka kopo, sheba litšoaneleho tsa ho qeta nako le mocheso.

4.Exhaust control silencer

Ho na le mefuta e mengata ea likhase tse tukang.Likhase tse ling li kotsi haholo, tse ling ha li kotsi.Setheo sa Naha sa Tshireletso ya Tikoloho (EPA) se tiisa melao ya kgase e ditshila ho fokotsa mesi e kotsi ya kgase.

State Environmental Protection Administration e laola ka thata ho tsoa ha jenereithara tse fanang ka matla a maholo.Melao ea hajoale e amehang e hloka hore ho sebelisoe li-converter tsa catalytic.Mofetoleli oa motheo o entsoe ho tloha marang-rang a cellular 'me o kenngoa ka ho toba tsamaisong ea ho qeta ka mor'a pipe ea ho qeta.Boemong bona, khase ea ho qeta e ka fihla mocheso o phahameng o hlokahalang bakeng sa ts'ebetso e tloaelehileng.Li-silencer tse ngata tse ncha li sebelisa motsoako oa li-converter le li-silencer.

Litokisetso tse amehang li boetse li amana le litaba tsa karolo e itseng ea khase ea exhaust.Likahare tsa mosi oa khase ea mouoane li ka fokotsoa ka ho sebelisa filthara ea particulate.Lera le ka hare la sesefa se entsoe ka thepa ea ceramic.Khase ea ho qeta e bokelloa ka thepa le mosili.Lienjineri tsa ho chesa li ka boela tsa sebelisa li-additives ho fokotsa ho tsoa ha khase e kotsi.

Boemo ba molumo oa lerata

Matla a molumo a hlahisoang ke phala ea exhaust a lekanngoa ka li-decibel.Decibel ke tekanyo ea tekanyo e sebelisetsoang ho emela karo-karolelano ea tšobotsi e le 'ngoe ho sekala se seng sa logarithmic.Boleng ba decibel ke mokhoa oa ho metha o ts'oanang le karabelo ea tsebe ea motho ho molumo.

Barekisi ba pele ba ne ba arotsoe ka limaraka tse 'nè tsa motheo.Maemo a indasteri, a khoebo, a bolulo le a sepetlele a nkoa e le litekanyetso tsa indasteri bakeng sa tlhahiso ea li-silencers.Ka nako e ts'oanang, liphello tsa ho fokotsa molumo oa bahlahisi ba fapaneng le tsona li fapane.The Generation Systems Association (EGSA) e thehile lethathamo la litataiso tsa litekanyetso ho fana ka litekanyetso tse kopaneng tsa moferefere bakeng sa bahlahisi bohle ba mokhatlo.E fetohile tekanyetso ea indasteri ea tlhahiso.

Maemo a tloaelehileng ke:

Boemo ba indasteri - fokotsa lerata ka 15 ho isa ho 20 dB.

Boemo ba bolulo - fokotsa lerata la ho ntša metsi ka 20 ho isa ho 25 dB.

Boemo ba bohlokoa - ho fokotsa lerata la ho tima 25-32 dB.

Boleng bo bohlokoa haholo - fokotsa lerata ka 30-38 dB.

Boemo ba bongaka - fokotsa lerata la ho tima ka 35-42 dB.

Boemo bo eketsehileng ba sepetlele - fokotsa lerata la ho qeta ka 35-50 dB.

Boemo ba moeli - fokotsa lerata ka 40-55 dB.

Ho feta tekanyo - fokotsa lerata ka 45-60 dB.

Ho lokela ho hlokomeloa hore ha se sebui se seng le se seng le setaele se ka sebetsang maemong ohle.Bahlahisi ba fapaneng ba hlahisa mefuta e fapaneng, mme litšenyehelo tsa bona tsa tlhahiso le thepa ea 'mele ea li-silencers li lekanya boemo ba ho fumaneha.
