Ukungasebenzi kahle kwesitofu seVolkswagen Jetta

Umbono osabalele phakathi kwabashayeli bezimoto ezifuywayo wokuthi izimoto zaseJalimane ziwela phansi kuyaqabukela - i-stereotype, eqinisweni ekude neqiniso njalo. Ikakhulukazi uma kuziwa ekushiseni kwesikhala: ngenxa yezizathu ezicacile, isitofu seVolkswagen Jetta asiklanyelwe ukusebenza ezimweni ezimbi kangaka zesimo sezulu esivamile engxenyeni enkulu yensimu yezwe lethu. Kodwa-ke, izici eziningi ezengeziwe zithinta ukusebenza kwesistimu yokupholisa, kusukela kukhwalithi yoketshezi lobuchwepheshe olusetshenziswayo kanye nemvamisa yoshintsho lwesihlungi kuya kusitayela sokushayela ngakunye nezimo zomgwaqo. Ngakho-ke, izimo lapho i-Volkswagen Jetta isitofu iqhwa ayivelakancane.

Ukuxazulula inkinga ngesitofu kuVolkswagen Jetta.

Sizokutshela ukuthi kungani lokhu kungenzeka nokuthi ungabhekana kanjani nomkhuhlane ekamelweni. Njengoba isici sokushisa siyingxenye yesistimu yokupholisa yeyunithi yamandla, kungaba nezizathu eziningi zokuhluleka kwesitofu:

• ukuvuza kwefriji;
• ukukhululeka komgwaqo;
• ifeni yesitofu esingalungile;
• i-heater core engcolile;
• ukuvimbela i-thermostat;
• ukwehluleka kwephampu;
• ikhanda gasket liyavuza.

Ake sicabangele ngalinye lala maphutha ngokuningiliziwe.

Ukuvuza kwe-Antifreeze

I-Coolant iyingxube yamanzi kanye nezingxenye ezivimbela ukwakheka ekuqandiseni emazingeni okushisa aphansi. I-antifreeze noma i-antifreeze ibiza kakhulu, ngakho-ke ukwehla okungalawuleki kwezinga lokupholisa kubi, okungenani ngokwezindleko zezezimali. Ku-VW Jetta, le nqubo igadwa inzwa ehambisanayo, ukuze ingalokothi ibonakale. Kodwa-ke, inkinga itholakala ekutholeni indawo yokuvuza, ngoba le nqubo ayihlali ihambisana nokwakhiwa kwama-puddles ngaphansi kwemoto. Isistimu yokupholisa yakhiwe izingxenye eziningi, ngayinye inomthombo wayo wokuvuza. Yiqiniso, lezi zombili ziyi-radiator - eyinhloko nesithando somlilo, kodwa uma kunezinkinga ezimbalwa kakhulu ngokulungisa owokuqala, kuzodingeka ujuluke ukuze ususe i-radiator ku-heater. Futhi ukuvala imbobo ngokwayo akuyona inqubo elula.

Kunoma yikuphi, ukulungiswa okunjalo kwenziwa ngengozi yakho kanye nengozi. Kulula kakhulu ukuqeda ukuvuza uma umthombo wayo uwukuhlangana kwamapayipi namapayipi; lapha ungathola ngokuqinisa noma ukufaka esikhundleni se-clamps, futhi esimweni sokugcina kunconywa ukusebenzisa i-sealant. Uma kukhona ukuqhekeka kuma-hoses, inkinga ixazululwa ngokuyishintsha. I-gasket ye-thermostat ingavuza, okuyinto, empeleni, engeyimbi njenge-cylinder head gasket ephukile. Okunye okungaba khona ukuvuza okupholisayo ithangi lokunweba lepulasitiki. Imifantu ivama ukumila emzimbeni wayo noma isivimbo, okuthi, lapho isihlolisiswa, sihlukaniswe njengemihuzuko. Nokho, inzwa yezinga lokupholisa ngokwayo ingahluleka. Kulokhu, ukuvuza kungatholwa ngesikhathi kuphela ngokuhlola njalo izinga ku-RB. Uma lokhu kungenziwa.

Umoya onguthelawayeka

Njengomthetho ojwayelekile, noma yimuphi umthombo wokuvuza kwe-antifreeze yilapho umoya ungena khona ohlelweni. Ngakho-ke, ukwehla kwezinga lokupholisa cishe njalo kuhambisana nokubonakala kwamaphakethe omoya avimbela ukujikeleza okuvamile kwesipholile ngomugqa. Inkinga efanayo ivame ukwenzeka lapho kushintsha i-antifreeze, uma imithetho ethile ingalandelwa. Njengoba indawo ephakeme kakhulu ye-CO kuVolkswagen Jetta iyisitofu, hhayi ithangi lokunweba, ukuvinjwa komoya kuvame ukwenzeka lapha. Indlela elula yokususa ukukhanya ukushayela kuze kufike phezulu (engxenyeni ethambekele) bese ucindezela igesi imizuzu engu-5-10. Umoya kufanele uphume ngesivalo sethangi lokunweba. Abanye abanikazi bezimoto benza le nqubo ngaphandle kwepulaki, kodwa lokhu akudingekile: kukhona imbobo yokukhipha amanzi kupulaki. Lapha kubalulekile

Ukuhluleka kwefeni yesithando somlilo

Uma isitofu se-Jetta 2 singashisi kahle, ifeni enephutha ingaba imbangela. Kulokhu, i-coolant eshisayo izofudumeza ngokwanele umoya kurediyetha yesitofu, kodwa lo moya oshisayo uzogelezela endaweni yabagibeli ngamandla adonsela phansi, okusobala ukuthi akwanele ukushisa indawo yabagibeli. Inkinga itholakala kalula kakhulu: uma umoya oshisayo uphuma kuma-deflectors, kodwa cishe awushayi, kungakhathaliseki ukuthi imodi yokushaya ivuliwe, khona-ke umshicileli we-heater unephutha. Akubona ngaso sonke isikhathi ukungasebenzi kahle okunjalo kuhlotshaniswa nokungasebenzi kwe-fan. Okokuqala udinga ukuhlola ukuthi ama-fuses V13 / V33, atholakala ku-SC block futhi anesibopho sokusebenza kwe-fan yesitofu kanye nesistimu yesimo sezulu, aqhume. Uma ziphelele, hlola ukuthi amandla anikezwayo kumatheminali azo, izintambo zingamane zonakaliswe. Uma konke kuhamba kahle lapha, khona-ke ukungasebenzi kahle kuxhunywe ngempela ne-fan kagesi ngokwayo. Okokuqala udinga ukuyihlukanisa. Lokhu kwenziwa ngale ndlela elandelayo:

• hambisa isihlalo somgibeli ngaphambili yonke indlela emuva;
• sibeka isibani bese silala ngaphansi kwe-torpedo;
• qaqa izikulufu ezimbili ezibambe isivikelo;
• nqamula isixhumi samandla ku-motor kagesi;
• donsela amafulegi ngakuwe, bese uphendulela ifeni ngokuphambene newashi cishe ngamasentimitha angu-3-4 bese wehlisa;
• uma i-impeller ingaguquki noma ijikeleze ngobunzima obukhulu, ngokusobala, i-fan bear idiliziwe, khona-ke kufanele ishintshwe;
• ngokuvamile izinkinga ngesiphephetha-moya ukungcoliswa kwayo; kulokhu, yihlanze futhi uyifake endaweni.

Ngokomthetho, imisindo kanye ne-squeaks ekhishwe ngesikhathi sokusebenza kwayo kuzobonisa ukuthi umshayeli ungcolile, nakuba izimpawu ezifanayo nazo ziyisici sokuthwala okugugile kakhulu.

Irediyetha engcolile

Le nkinga ijwayelekile kuwo womabili ama-radiators, kanti uma imoto indala, ivaleka kakhulu. Isimo sibhebhethekiswa ukusetshenziswa kokupholisa okunekhwalithi ephansi: abashayeli bethu benza iphutha lokusebenzisa izinhlanganisela zasekhaya, futhi ngokufika kokushisa, abaningi ngokuvamile bashintshela emanzini ukuze bonge imali: uma kwenzeka kuvuza okupholisayo, kuyaba nzima. ngokuvamile kuyabiza ukwengeza isinqamuleli. Phakathi naleso sikhathi, amanzi, ikakhulukazi avela empompini, aqukethe ukungcola okuningi okuhlala ezindongeni zamashubhu e-radiator ngendlela yesikali, okuphazamisa kakhulu ukudluliswa kokushisa kwayo. Ngenxa yalokho, uketshezi ku-radiator eyinhloko alupholi kahle, okuholela ekushiseni ngokweqile kweyunithi yamandla, futhi uma i-radiator yesitofu se-Jetta 2 ivalekile, umoya ongena ekamelweni labagibeli awufudumala kahle. Inkinga ixazululwa ngokuhlanza noma ukufaka esikhundleni ngokuphelele i-radiator. Ezimotweni ezine-mileage ephansi (kufika kumakhilomitha ayizinkulungwane eziyi-100-150-200), ungazama inketho eshibhile. Ubuchwepheshe bokugeza:

• isipholile esidala siyakhanywa;
• womabili amapayipi kahhavini anqanyuliwe;
• sixhuma i-hose yethu epayipini lokudonsa lobude obanele ukuze singafaki isikhala ngaphansi kwemoto ngoketshezi olungcolile lwe-washer;
• uma kukhona ipompo noma i-compressor, khona-ke ungazama ukuqeda izinsalela ze-antifreeze ngokunikeza umoya ocindezelwe kwipayipi yokungena;
• gcwalisa ipayipi lokungena nge-electrolyte evamile (sisebenzisa ibhodlela lepulasitiki elinqunywe ngendlela yensimbi, umkhawulo ongaphezulu okufanele ube ngaphezu kwe-radiator ngokwayo;
• shiya lolu ketshezi cishe ihora, bese uhlunga;
• silungiselela ibhakede ngamanzi ashisayo agijimayo, sehlise amapayipi womabili lapho bese sivula iphampu, okufanele iqhube uketshezi kuzo zombili izinkomba, sishintsha amanzi njengoba engcolile;
• senza umsebenzi ofanayo, kodwa esikhundleni samanzi sisebenzisa isisombululo esilungiselelwe kusuka kumalitha amathathu we-silite namalitha amabili wesondo, ahlanjululwe emanzini ashisayo;
• hlambulula i-radiator futhi ngamanzi ashisayo ngamagremu angu-400 we-citric acid engeziwe futhi uqedele inqubo ngaphansi kwamanzi asebenzayo.

Njengomthetho, ukukhishwa okunjalo kunikeza imiphumela emihle; Lapho uthela i-antifreeze entsha, kubalulekile ukususa umoya ohlelweni.

I-thermostat engalungile

I-valve ye-thermostat evalekile iwukungasebenzi kahle kwazo zonke izimoto ngaphandle kokukhetha. Imvamisa, injini kufanele ifudumale ifike kuzinga lokushisa lokusebenza kungakapheli imizuzu eyi-10 ngenkathi ushayela (ebusika, ukungenzi lutho kungathatha isikhathi eside). Uma ukuhamba kwe-valve kuphazamiseka, okwenziwa lula ukwakheka kwesikali ezindongeni zangaphakathi ze-thermostat, iqala ukugoba futhi ekugcineni iyeke ukunyakaza ngokuphelele, futhi lokhu kungenzeka endaweni evulekile, evaliwe noma ephakathi. Ukushintsha i-thermostat akuyona inqubo enzima, inkinga enkulu ukudilizwa kwamapayipi, njengoba ngokuvamile i-clamp ne-hose inamathela ekufakeni, futhi kuzodingeka udlale ngokususwa kwayo. Ukulandelana kwezenzo zokushintsha i-thermostat:

• khulula ipulaki ye-RB;
• faka isitsha se-antifreeze ngaphansi kwe-thermostat;
• khipha amapayipi;
• ngokhiye we-10, qaqa izikulufu ezimbili ezibambe i-thermostat enjinini;
• susa i-thermostat kanye ne-gasket;
• silinda imizuzu engu-10-15 kuze kube yilapho i-coolant ihlangana;
• faka ingxenye entsha;
• engeza i-antifreeze entsha.

Ukuhlonza ukungasebenzi kahle kwe-thermostat nakho kulula: ngemva kokuqala injini ebandayo, ishubhu eliphezulu kufanele lishise ngokushesha, futhi ishubhu eliphansi kufanele liphole kuze kube yilapho izinga lokushisa elipholile lifinyelela kuma-degree angu-70, ngemva kwalokho ishubhu eliphansi liqala ukushisa. Uma lokhu kungenzeki, noma amapayipi ashisa ngesikhathi esifanayo, i-valve inamathela.

Ukuhluleka kwepompo

Uma isiphephetha-moya sinomthwalo wemfanelo wokuphoqelela umoya endaweni yabagibeli, khona-ke iphampu ishayela into epholile emugqeni, kuhlanganise nerediyetha yesitofu. Ukube ibingekho iphampu, bekungeke kube khona iphuzu ekusebenziseni isibandisi. Ukungasebenzi kahle kwepompo lamanzi kuzothinta nakanjani kokubili ukusebenza kahle kokushisa kwangaphakathi (kulokhu, isitofu seVolkswagen Jetta 2 sizoshisa kahle) kanye nokusebenza kweyunithi yamandla, ezoqala ukushisa ngokweqile, ezotholwa yinzwa yokushisa epholile. Ngakho-ke, izinkinga zokuxilonga lokhu kungasebenzi kahle ngokuvamile azenzeki. Ngokuqondene nokulungiswa, kuhlanganisa ukufaka esikhundleni sepompo engalungile, futhi lokhu kusebenza kungenziwa ngokuzimela. Njengenjwayelo.

Futhi, ipompo ingase yehluleke ngenxa yokushisa ngokweqile, okuholela ekubhujisweni kwendandatho yokubeka uphawu noma ukuguqulwa kwe-impeller nokuvala kwayo. Uma uqinisekile ukuthi ipompo yamanzi iyimbangela yokushisa kwenjini ekhulayo, kufanelekile ukuhlola isimo sophawu kanye namapayipi okuxhuma. Uma konke kuhlelekile ngalokhu, kufanele uqale ukhiphe i-antifreeze futhi unqamule i-terminal yebhethri engalungile. Iphampu yeVolkswagen Jetta ishintshwa ngokulandelana okulandelayo:

• qaqa ijeneretha ngokuqaqa izikulufo ezine;
• khulula i-clamp kwipayipi engezansi ye-radiator eyinhloko;
• khipha i-hose bese ukhipha isipholile esitsheni esilungisiwe;
• khulula i-flange yepulasitiki ngemuva kwe-thermostat;
• khipha i-pulley yokudlulisa iphampu ngokukhulula amabhawodi amathathu ngokhiye wesi-6;
• kusele ukuqaqa iphampu, exhunywe emzimbeni weyunithi yamandla ngamabholithi ayishumi ayi-10;
• faka iphampu entsha futhi wenze yonke imisebenzi ngokulandelana;
• gcwalisa isipholile esisha bese wopha ama-airbag.

Ngendlela, lapho ushintsha ipompo, ungabheka isimo sebhande futhi, uma kunesidingo, uyishintshe.

I-gasket yekhanda lesilinda elivuzayo

Lokhu kungasebenzi akuvamile, kodwa, ngaphezu kokuwohloka kokusebenza kwe-heater evamile, kusongela iyunithi yamandla ngezinkinga ezinkulu. Ukuxilonga inkinga kulula. Uma ukuvuza kwe-antifreeze kwenzeka, okuhambisana nokushintsha kombala we-exhaust usuka obala uye ekubeni mhlophe ogqinsile, lokhu kubonisa ukugeleza koketshezi kumasilinda bese kungena kusifinyili. Ukuvuza kwe-head gasket kuyinkinga enkulu, njengoba into epholile izophinde ingene ohlelweni lokuthambisa, inciphise i-viscosity kawoyela wenjini, okuholela ekwehleni okukhulu kwempilo yenjini. Ngakho-ke, uma kutholakala ukungasebenzi kahle, kuyadingeka ukufaka esikhundleni se-gasket ngokushesha ngangokunokwenzeka. Le nqubo inomthwalo wemfanelo, kodwa ungayenza ngokwakho. Uma kungekho okuhlangenwe nakho kokuhlakaza ikhanda le-cylinder, kungcono ukuxhumana nochwepheshe.
