Umsebenzi oyinhloko wenhlangano yefeni yokupholisa yezimoto
Ukuhlanganiswa kwefeni yokupholisa yezimoto kuyingxenye ebalulekile yesistimu yokupholisa injini. Umsebenzi wayo oyinhloko ukuqinisekisa ukuthi injini isebenza njalo ngaphakathi kwebanga lokushisa elifanele, isebenza "njengomqaphi wokulawula izinga lokushisa" wenjini.
Ngokombono oyisisekelo, kuthuthukisa ukusebenza kahle kokupholisa kwe-radiator ngokusheshisa ukuhamba komoya. Uma injini isebenza, ukushiswa kukaphethiloli kumasilinda kukhiqiza ukushisa okukhulu. Uma lokhu kushisa kungasuswa ngokushesha, kuzokwenza injini ishise ngokweqile. Ezimweni ezincane, lokhu kuholela ekunciphiseni kwamandla kanye nokwanda kokusetshenziswa kukaphethiloli; ezimweni ezimbi kakhulu, kungabangela ukwehluleka okukhulu njengokubanjwa noma ukuqhuma. I-fan assembly yokupholisa, ngaphansi kwempendulo yesignali yenzwa yokushisa kwamanzi, ilungisa ngokuhlakanipha isivinini sayo sokujikeleza: lapho izinga lokushisa lamanzi liphansi, ifeni isebenza ngesivinini esiphansi noma ima ngokuphelele ukuvimbela ukupholisa ngokweqile kwenjini; lapho izinga lokushisa lamanzi lifinyelela inani elibalulekile, ifeni izojikeleza ngesivinini esiphezulu, isheshise ukujikeleza komoya ebusweni be-radiator futhi ivumele i-coolant ukuthi isuse ukushisa ngempumelelo, igcine injini ekushiseni okusebenzayo okuhle okungaba ngu-90°C.
Ezimweni zokusebenza eziyinkimbinkimbi, indima yokuhlanganiswa kwefeni yokupholisa iba yinto evelele kakhulu. Isibonelo, emigwaqweni yasemadolobheni egcwele abantu abaningi, lapho imoto ingasebenzi, umoya wemvelo awunawo umthelela omkhulu ekushabalaleni kokushisa. Ngalesi sikhathi, ifeni iyaqhubeka nokusebenza ukuze "ipholise futhi inciphise ukushisa" kwenjini; lapho umoya opholile uvuliwe, ingasiza futhi i-condenser ekupholiseni, iqinisekise ukusebenza kahle kohlelo lokupholisa umoya. Ezimotweni zikagesi, ukuhlanganiswa kwefeni yokupholisa nakho kunesibopho sokupholisa izingxenye eziyinhloko ezifana namabhethri nama-motor, okuthinta ngqo ububanzi bemoto kanye nesikhathi sokuphila kwebhethri.
Ngaphezu kwalokho, ngokuthuthukiswa kobuchwepheshe bezimoto, izinhlangano zabalandeli bokupholisa ezihlakaniphile zingalungisa ngokunembile amandla okupholisa ngokusekelwe ezilinganisweni eziningi zedatha njengomthwalo wenjini, isivinini semoto, kanye nokushisa kwemvelo, ukuqinisekisa umphumela wokupholisa ngenkathi kunciphisa ukusetshenziswa kwamandla kwazo, okuhambisana nomkhuba wamanje wokongiwa kwamandla nokuvikelwa kwemvelo embonini yezimoto.
Amaphutha avamile kanye nezixazululo zenhlangano yabalandeli bokupholisa
Ukwehluleka kwesistimu yokulawula kagesi
Uhlelo lokulawula lwe-elekthronikhi "luyingqondo" yenhlangano yefeni yokupholisa. Uma seluhlulekile, luzothinta ngqo ukusebenza okuvamile kwefeni. Amaphutha avamile afaka phakathi ukwehluleka kweswishi yokulawula izinga lokushisa, ukusha koxhumana nabo be-relay, kanye nohlelo olungavamile lwemojuli yokulawula. Isibonelo, ngemva kokuba oxhumana nabo bangaphakathi beswishi yokulawula izinga lokushisa sebeshile, abakwazi ukuzwa izinga lokushisa le-coolant ngokunembile, okwenza ifeni ingalokothi iqale noma isebenze ngesivinini esiphezulu njalo. Ezimweni ezinjalo, umnikazi angasebenzisa i-multimeter kuqala ukuthola ukuqhubeka kwesekethe, futhi ahlole kuqala izingxenye ezonakele kalula njenge-fuse kanye ne-relay. Uma inkinga ikumojuli yokulawula, ithuluzi lokuxilonga lochwepheshe kufanele lisetshenziswe ukufunda ikhodi yephutha ukuze kulungiswe noma kushintshwe ngokunembile.
Ukujikijela isakhiwo semishini
Ukuminyana kwemishini kuyiphutha elivamile lenhlangano yefeni yokupholisa, elivame ukubangelwa izinto zangaphandle ezibamba noma ezigugile. Ngesikhathi sokusebenza kwemoto, imfucumfucu efana nama-lime ezihlahla, amaqabunga, nezidumbu zezinambuzane inganamathela kalula ebusweni be-radiator. Uma ingahlanzwa njalo, ingamuncwa ifeni, okubangela ukuthi ama-blade abambeke nezinto zangaphandle. Lokhu kungabangela imisindo emincane noma umonakalo omkhulu enjinini ngenxa yomthwalo omkhulu. Ngaphezu kwalokho, ngemva kokusebenza isikhathi eside, amafutha okugcoba ama-fan bearing ayoma kancane kancane, okubangela ukuguguleka nomsindo, futhi ezimweni ezimbi kakhulu, ingase ivimbe futhi iyeke ukujikeleza. Ngesikhathi sokulungiswa okuvamile, amafeni kufanele ahlanzwe njalo, futhi isimo sama-bearing kufanele sihlolwe ngemva kwamakhilomitha ayizinkulungwane ezingu-5-8 okushayela. Uma kudingeka, inhlangano kufanele ishintshwe.
I-anomaly yesistimu yokunikezwa kwamandla
Uhlelo lokuphakelwa kwamandla luwumthombo wamandla wenhlangano yefeni yokupholisa. Izinkinga ezifana nokuntuleka kwamandla ebhethri, ukuxhumana okungekuhle komugqa, kanye nama-fuse avuvukile konke kungabangela ukuthi ifeni yehluleke ukusebenza kahle. Ama-wiring harnesses ezimoto ezindala avame ukubola nokugqwala, okuholela ekudlulisweni kwamandla kagesi okungekuhle; ukuguqula amafeni amakhulu kungadlula umthwalo wezintambo zemoto yokuqala, okwandisa ingozi yamaphutha. Umnikazi angaphatha i-fuse eyengeziwe. Uma ifeni iyeka ukujikeleza, qala uhlole ukuthi i-fuse ivuvukile yini. Uma kuqinisekisiwe ukuthi iyinkinga yezintambo, hlanza izindawo ezivuvukile noma ushintshe i-wiring harness ukuze ugweme izinkinga ezinkulu ezibangelwa amaphutha amancane.
Ukubonakaliswa okuvamile kwamaphutha
Amaphutha okuhlanganisa ifeni lokupholisa avame ukukhipha "izibonakaliso zesexwayiso" ezisobala. Inkinga evame kakhulu ukuthi izinga lokushisa lamanzi enjini liphezulu kakhulu. Igeyiji lokushisa lamanzi kudeshibhodi ibonisa inkomba eseduze noma edlula umugqa obomvu. Uma ingaxazululwa ngokushesha, lokhu kungaholela ekulimaleni okukhulu enjinini. Inkinga yesibili imisindo engavamile. Lapho ama-fan blades egugile, ekhubazekile, noma ama-bearings onakele, kuzovela imisindo yokungqubuzana ebukhali noma imisindo yokubhonga. Ngaphezu kwalokho, ukusebenza kabi kokupholisa umoya opholile nakho kungahlobene nokwehluleka kwefeni. Ngenxa yokuthi ifeni ayikwazi ukuqeda ukushisa kwe-condenser ngempumelelo, izobangela ukujikeleza okubi kwe-refrigerant kanye nokwehla kokusebenza kahle kokupholisa.
