Ukuvuza kwe-exhaust kwethula izinkinga ezisheshayo zokushayeleka—kusukela kuntuthu wentuthu yekhabethe kanye nokuhlola okuphumayo okuhlulekile kuya ekusebenzeni kwenjini okonakele nomsindo oweqisayo. Nakuba ukushintshwa kwengxenye egcwele noma ukushisela okuchwepheshile kwe-TIG/MIG kuwukulungisa okuqinisekile, lezi zinketho zivame ukuvimbela izindleko noma akunakwenzeka ngokomzimba kumasistimu wokuguga okuguga nokugqwala kwendawo yonke. Ukulungiswa kwe-DIY kuvame ukwehluleka ngoba abasebenzisi abaqondi ukulinganiselwa ngokomzimba kwama-chemical sealant ngaphansi kokuhamba ngebhayisikili okushisayo nokudlidliza.
Ukulungisa ngempumelelo kuncike ngokuphelele ekufaniseni inhlanganisela yekhemikhali efanele nohlobo oluthile lokuvuza (ilunga elishelelayo elihambisana nokuqhekeka kwesakhiwo) kanye nokwenza ukulungiswa okuqinile kwendawo. Lo mhlahlandlela uchaza indlela yokuhlola, ukukhetha, nokusebenzisa i- i-exhaust system sealer yokulungiswa okuhlala isikhathi eside, nokuqinisekiswa.
Ukulungiselela Kudinga Ukuphila Isikhathi Eside: Ngaphezu kwama-80% wokwehluleka komshini wokukhipha umoya okhipha umoya kubangelwa ukungalungiseki kahle kwendawo. Ukuthintana kwensimbi engenalutho, okungenayo i-carbon deposit kanye ne-iron oxide (ukugqwala), kuyimfuneko okungaxoxiswana ngayo.
Qondanisa Inhlanganisela Nesici: Okunamathiselwe kwensimbi okunezinga eliphezulu lokushisa kuyagqama ekuvaleni amalunga ashelelayo kanye nezikhala ezincane ze-flange, kuyilapho amabhandeshi aqiniswe nge-fiberglass, amaribhoni e-exhaust, noma ama-putty ayadingeka ukuze kuvalwe izimbobo ezibonakalayo ezigabeni zamapayipi aqondile.
Ukwelapha Okushisayo Kuyisibopho: Iningi lama-exhaust sealants esezingeni eliphezulu lidinga inqubo ethile yokushisisa ukushisa (ukumisa injini ukuze ifinyelele izinga lokushisa elisebenzayo) ukuze ixhumanise ama-polymer futhi ifinyelele ubulukhuni bawo besakhiwo obulinganiselwe.
Qonda Imikhawulo: Ayikho i-exhaust sealer yesistimu ethatha indawo yensimbi. Ama-sealant awakwazi ukuthwala imithwalo eyimishini noma abambe ndawonye amapayipi anqanyuliwe ngaphandle kokwengezwa kwehardware ebonakalayo (ama-clamps noma imikhono).
Ngaphambi kokuvula ishubhu lokunamathisela amakhemikhali, kufanele uchaze ukuthi yini eyenza ikhandidethi elisebenzayo lokuvala uphawu ngamakhemikhali uma liqhathaniswa nokushintshwa kwemishini okuyimpoqo. Akuwona wonke ama-exhaust avuzayo angalungiswa nge-sealant. Udinga ukungena ngaphansi kwe-chassis, uhlole amapayipi, futhi uqonde ubuqotho besakhiwo bensimbi osebenza ngayo.
Uhlobo oluthile lwesici lubeka indlela yakho yokulungisa. Amasistimu wokukhipha umoya abekezelela izindawo eziyingozi kakhulu, futhi umonakalo awugcinayo uyahlukahluka ngendawo nesakhiwo sengxenye. Kufanele uhlukanise ukuvuza ngokwezigaba ngokunembile ngaphambi kokuqhubeka.
Amajoyinti ama-slip-fit nama-flange ngokuvamile ayavuza ngenxa yokugoqa okuxekethile, ama-gaskets awonakele, noma ukuhlanekezelwa kwamapayipi amancane kusukela ekuqineni okwedlulele kwangaphambilini. Lezi zindawo zinokusebenza okuphezulu kwezinsimbi zokunamathisela ngenxa yokuthi isakhiwo sensimbi esingaphansi sihlala sinjalo. Isitywini sisebenza njengendawo yokuvala igebe phakathi kwezingcezu ezimbili eziqinile zensimbi.
Ama-muffler seams kanye nokushisela kuvame ukwenza ukuvuza kwe-pinhole kuma-crimp efektri noma amajoyinti e-weld. Lokhu kwenzeka ngenxa yokuhlanganisa i-condensation yangaphakathi. Lapho injini igijima, umhwamuko wamanzi uyajiya ezingxenyeni ezipholile ze-exhaust, udale umswakama oneasidi odla insimbi kusukela ngaphakathi ukuya ngaphandle. Lokhu kunikeza ukusebenza kahle kokulungisa, kuye ngokuthi ukugqwala kwangaphakathi kusabalele kangakanani.
Ukuqhekeka kwamapayipi esakhiwo kanye nama-blowholes aveza izikhala ezinkulu ezibangelwa i-oxidation ethuthukisiwe. Lezi zinokusebenza okuphansi kokunamathisela kuphela. Awukwazi ukuvala imbobo enkulu nge-ceramic paste; izomane iwe noma iqhume ngaphansi kwengcindezi. Lawa maphutha adinga amabhandeshi, ukupeshiswa kwensimbi ngokwezifiso, noma imikhono eyimishini ukuvala igebe ngempumelelo.
Linganisa ubukhulu bodonga obusele bepayipi elizungezile. Thatha i-screwdriver ye-flathead bese ucindezela ngokuqinile ngokumelene nensimbi ezungeze ukuvuza. Uma insimbi ikhiqiza, igoqa, noma ihlakazeka ngaphansi kwengcindezi emaphakathi, isitywini sizohluleka. I-paste idinga insimbi eqinile, ezinzile ukuze inamathele kuyo. Uma i-substrate ibola, i-sealer izovele iwe kanye nongqimba olulandelayo lokugqwala.
Hlola indawo ngokucophelela. Ama-sealer ngokuvamile akufanele asetshenziswe phezulu kwesiguquli se-catalytic noma kuma-nifold exhaust. Amazinga okushisa kulezi zindawo ngokuvamile adlula u-2,000°F (1,093°C), futhi ukucindezela kwegesi ephumayo kuphezulu kakhulu. Izinsimbi zamakhemikhali ezisetshenziswa lapha zizolulaza ngokushesha, ziqhekeke, futhi ziqhume.

Ukukhetha umkhiqizo ofanele kubalulekile ukuze kulungiswe unomphela. Amafomula ahlukene aphatha ukushisa, ukudlidliza, namasayizi wegebe ngendlela ehlukile. Ukusebenzisa ikhemistri engalungile ngokuvuza kwakho okuthile kuqinisekisa ukubuya.
Lawa manamathisela elapha abe yinqwaba eqinile, efana nensimbi lapho evezwe ekushiseni. Basebenzisa isisekelo se-sodium silicate esixutshwe ne-ceramic noma izimpushana zensimbi. Lapho amanzi akunamathisela ehwamuka phakathi nomjikelezo wokushisa, ama-silicates acwebezela, akhe isakhiwo esiqinile esimelana kakhulu nokuwohloka kwamakhemikhali kanye nezinga lokushisa elidlulele.
Asebenza kahle kakhulu ekuxhumekeni kokushelela, ukuvala ukufakwa kwama-clamp amasha, nokugcwalisa imifantu yezinwele. Ngenxa yokuthi zelaphekela esimweni esiqinile, abakwazi ukubhekana nokuguquguquka okukhulu. Uma uhlelo lwe-exhaust luhamba kakhulu, unamathisele ophulukisiwe uzophuka.
Lesi sigaba sisebenzisa inhlaka ekwazi ukumelana nokushisa ehlanganiswe ne-fiberglass matrix elukiwe ukuvala izikhala. Zingcono kakhulu ukuvala izimbobo ezibonakalayo (kufika kumayintshi angu-1-2) lapho ukunamathisela kukodwa kungawela khona. I-fiberglass inikeza iwebhu yesakhiwo ukuze i-resin ibambelele kuyo ngesikhathi senqubo yokwelapha.
Uma usebenzisa i-bandage, uyigoqa ngokuqinile engxenyeni yepayipi eyonakele. Njengoba i-exhaust ishisa, i-resin efaka i-fiberglass iyaqina, idale uhlaka oluyinhlanganisela oluzungeze ipayipi. Lokhu kusebenza kahle kakhulu ezigabeni eziqondile zamapayipi aphakathi nendawo akhiqize izimbobo zokugqwala.
Lawa amapheshana anamathelayo aqiniswe ngensimbi noma afakwe inhlaka ahlanganiswe ngokuqinile azungeze amalunga ukuze akhe i-gasket yesakhiwo. Angcono kakhulu ukuphinda avale amalunga esitayela sakudala sakwaFord, imikhono evuthayo, nezingxenye zamapayipi ezingaqondani kahle kancane.
Amaribhoni awusizo ikakhulukazi uma unelunga elingeke lihlale kahle. Usonga iribhoni engxenyeni yesilisa yepayipi, ushelelisa ingxenye yesifazane phezu kwayo, bese uyicindezela phansi. Iribhoni lichoboza futhi ligcwalise izikhala ezingajwayelekile, livimbele igesi ukuthi ingaphumi.
I-silicone ye-Vulcanizing Yegumbi Lokushisa Okuphezulu (RTV) ihlala iguquguquka ngemva kokwelashwa. Ingcono kakhulu kuma-flange gaskets kanye nezigaba ze-tailpipe ezinezinga lokushisa eliphansi. Ngenxa yokuthi ihlala ithambile, iphatha ukudlidliza kanye nokunwetshwa okushisayo okungcono kakhulu kunokunamathisela okuqinile kobumba.
Kodwa-ke, i-silicone ye-RTV inemikhawulo eqinile. Ayikwazi ukumelana nokushisa okuqondile kwezihloko noma iziguquli ze-catalytic. Iningi le-RTV yethusi lezinga eliphezulu lezinga eliphezulu liphuma ku-700°F (371°C) ngezikhathi ezithile. Uma uyisebenzisa eduze kakhulu nenjini, izosha, iphenduke umlotha, futhi ifuthe, ikushiye nokuvuza okukhulu kanye nephunga elibi.
Ukuze uqinisekise ukulungiswa okuhlala njalo, hlola izidingo ezithile zesistimu yakho yokukhipha umoya ngokumelene namandla e-sealant. Kufanele ufunde ishidi ledatha yezobuchwepheshe lomkhiqizo ohlose ukuwusebenzisa.
Qhathanisa izinga lokushisa eliphakeme lokusebenza lendawo evuzayo ngokuqhathaniswa nomkhawulo omkhulu womkhiqizo. Izilinganiso eziningi zidinga izilinganiso ezingu-2000°F+. Amapayipi omsila angadinga kuphela izilinganiso ezingu-500°F. Ukusebenzisa i-silicone yezinga eliphansi engxenyeni yokushisa okuphezulu kuzoholela ekwehlulekeni okusheshayo kanye nentuthu enobuthi. Njalo phutha ohlangothini lwesixwayiso bese ukhetha umkhiqizo olinganiselwe okungenani ngo-300°F ngaphezu kwezinga lokushisa elilinganiselwe lokusebenza.
Hlola ukubekezelela kwegebe komkhiqizi. Okunamathiselwe okufakwe kugqinsi kuno-1/4 intshi kuvame ukuphathwa ukushaqeka okushisayo. Ingaphandle le-blob yokunamathisela ewugqinsi iyelapha futhi iyaqina, ivale umswakama ngaphakathi. Lapho lowo mswakama obanjiwe ubila, uyanwebeka futhi uhlukanise igobolondo elilashiwe. Uma igebe likhulu kuno-1/4 intshi, kufanele usebenzise ibhandishi noma isiqephu sensimbi ngokuhambisana nesitywini.
Linganisa amazinga okushisa e-ambient application. Ama-sealant amaningi adinga ukusetshenziswa okungaphezu kuka-50°F (10°C) kanye nesikhathi esimisiwe se-ambient samahora angu-30 ukuya kwamahora angu-24 ngaphambi kokwelapha ukushisa. Ukusheshisa lesi sinyathelo kuvala umswakama ngaphakathi kokunamathisela, kubangele ukuthi uqhume lapho injini iqala. Uma usebenza egaraji elibandayo, kufanele usebenzise isibhamu sokushisa ukuze ufudumeze kahle ipayipi lensimbi nomoya ozungezile ozungeze ukulungisa ngaphambi kokufaka unamathisele.
Ukusebenzisa kahle kudinga isineke nokubambelela ngokuqinile emithethweni yokulungiselela. Ukweqa izinyathelo lapha kuqinisekisa ukwehluleka.
Ukuhlanza ngomshini kuyisinyathelo sakho sokuqala. Awukwazi ukufaka isivalo phezu kokugqwala, isikali, noma umule. Sebenzisa ibhulashi locingo, indwangu ye-emery, noma i-angle grinder enesondo locingo ukuze ukhumule indawo ibe yinsimbi engenalutho, ecwebezelayo. Nweba indawo elungiselelwe okungenani amayintshi angu-2 ngaphezu kokuvuza kwangempela. Lokhu kunikeza isitywini umkhawulo obanzi, ohlanzekile wokubamba.
Okulandelayo, yenza i-chemical degreasing. Geza indawo ngesihlanzi sezingxenye zamabhuleki ezingena-chlorine noma i-acetone ehlanzekile ukuze ususe umle wekhabhoni, uwoyela, kanye nomswakama. Sula ngendwangu yesitolo ehlanzekile, engena-lint. Vumela i-solvent icishe ngokuphelele ngaphambi kokufaka isitywini. Noma iyiphi i-solvent eyinsalela izonciphisa unamathisele futhi yonakalise ukwakheka kwayo kwamakhemikhali.
Ngamajoyinti alingana ngokushelela, sebenzisa ubuhlalu obuyi-intshi engu-1/8-intshi okuqhubekayo ngaphakathi kwepayipi lesifazane nangaphandle kwepayipi lowesilisa ngaphambi kokuba ushelelise ndawonye. Lokhu kudala isivalo sangaphakathi esibamba igesi. Ungamane uyigcobe ngaphandle kwelunga ngemva kokuhlanganisa amapayipi; ukucindezela kwe-exhaust kuzophusha kalula isiqephu sangaphandle kude.
Ngokuqhekeka kwangaphandle noma ukuvuza kwe-muffler, sebenzisa ukunamathisela ezendlalelo eziqhubekayo, ezincane (cishe u-1/16 kuya ku-1/8 amayintshi) kune-slab eyodwa ewugqinsi. Lokhu kuvimbela amaphakethe omswakamo avaleleke ekubeni ahwamuke futhi aphume umoya ngesikhathi sokwelapha ukushisa. Sebenzisa ummese we-putty noma umunwe wegilavu omanzi ukuze uphaphe kahle emaphethelweni ensimbi engenalutho.
Ukuze uthole ukushelela kwesithuthuthu esibonakala kakhulu, esidlidliza kakhulu, vala i-chrome ezungezile noma izindawo ezipholishiwe ngeteyipu yomdwebi ngaphambi kokufaka. Sula ukuminya okumanzi ngokweqile ngokushesha ngendwangu ye-microfiber emanzi ukuze uvimbele ukungcoliswa kwezimonyo unomphela. Uma unamathisele we-silicate uqina ku-chrome, kuba nzima kakhulu ukukususa ngaphandle kokuklwebha isiphetho.
Ukuthembela kuphela ezintweni ezinamathelayo ze-sealer kuyingozi. Amandla omshini ngokuvamile ayadingeka. Uma ilunga lepayipi lingaphandle, ukusebenzisa iribhoni noma i-clamp kukodwa ngeke kumise ukuvuza. Kufanele ufake ungqimba oluningi lokunamathisela okunezinga lokushisa eliphezulu kwensimbi ngqo endaweni ehlangene yepayipi, uyisonge ngeribhoni yokukhipha umoya, bese ucindezela isigxivizo phezu kokuhlanganiswa okumanzi ukuze uphoqe ukunamathisela ungene ezikhaleni ezingajwayelekile.
Faka ama-U-bolt, ama-band clamp, noma imikhono yokukhipha amandla phezu kwelunga elivaliwe ngenkathi okunamathiselwe kusemanzi. I-sealer isebenza njenge-gasket; i-clamp inikeza ukuqina kwesakhiwo okudingekayo ukuze umelane nokucindezela kokukhipha kanye nokudlidliza. Qinisa ama-clamps esilinganisweni setorque esishiwo ngumkhiqizi. Ungaqinisi kakhulu, njengoba lokhu kungachoboza ipayipi futhi kudale ukuvuza okusha.
Vumela isikhathi sokusetha se-ambient esidingekayo, okuvamise ukuba yimizuzu engama-30-60 kuye ngomswakama nezinga lokushisa. Ungayiqalisi ngokushesha injini. Lapho isikhathi sokusetha se-ambient sesidlulile, qala injini bese uyiyeka ingasebenzi imizuzu eyi-10-15. Ukushisa kwegesi ekhishwayo kubhaka kancane kancane umswakama ku-ceramic/metallic paste, kuxhumanisa inhlanganisela ibe igobolondo eliqinile.
Gwema ukuvuselela injini phakathi nalesi sigaba. Ukuvuselela kudala ama-spikes angazelelwe ku-exhaust backpressure, okungabangela ukufutheka ngaphambi kokuba ikhambi liqedwe. Vumela injini ingasebenzi kahle kuze kube yilapho ipayipi lifinyelela izinga lokushisa eligcwele lokusebenza, bese uyivala futhi uyiyeke ipholile ngokuphelele. Lo mjikelezo we-thermal uvala isitywini endaweni.
Ngisho nangesicelo esicophelelayo, ubungozi obuthile bungonakalisa ukulungiswa. Ukuqonda lezi zindlela zokwehluleka kukuvumela ukuthi wakhe ukulungiswa okuqinile.
Ukucindezela kwe-exhaust ephezulu kungakhipha unamathisele omanzi ngaphambi kokuba uqine. Lokhu kuvame ukwenzeka lapho abasebenzisi bephelelwa isineke futhi baqale imoto ngokushesha ngemva kokufaka unama. Ukuze unciphise lokhu, bambelela ngokuqinile ezikhathini zokomisa ezizungezile ngaphambi kokwethula ingcindezi yokukhipha umoya. Ukuze uthole izikhala ezinkulu, sebenzisa i-wire mesh yangaphakathi ukuze ubambe ukunamathisela endaweni lapho kusetha. I-mesh isebenza njenge-rebar kukhonkolo, inikeza ukusekelwa kwesakhiwo sokunamathisela ngokumelene nokucindezela kwegesi.
Isitywini esiqinile singase siqhekeke futhi siphebeze ngemva kwamaviki ambalwa okushayela ngenxa yokunyakaza kwenjini nokushisisa nokupholisa ngokushesha. Amatshe e-Ceramic aqinile.
