Ifeni yokupholisa isebenza njalo
Okuqukethwe
Isimo lapho Ukupholisa fan egijima njalo kungabangelwa izizathu eziningana: ukwehluleka kwenzwa yokushisa epholile noma izintambo zayo, ukuphuka kwe-fan start relay, ukulimala kwezintambo ze-drive motor, "glitches" ye-electronic control unit ICE (ECU) nabanye abanye.
ukuze uqonde ukuthi ifeni yokupholisa kufanele isebenze kanjani ngendlela efanele, udinga ukwazi ukuthi yiliphi izinga lokushisa elihlelwe kuyunithi yokulawula ukuze uyivule. Noma bheka idatha kuswishi yabalandeli etholakala kurediyetha. Ngokuvamile kungaphakathi kuka + 87 ... + 95 ° C.
Esihlokweni, sizocubungula ngokuningiliziwe zonke izizathu eziyinhloko zokuthi kungani i-radiator yokupholisa injini yomlilo yangaphakathi isebenza hhayi kuphela lapho izinga lokushisa elipholile lifinyelela ama-degree angu-100, kodwa njalo lapho ukuthungela kucishiwe.
| Izizathu zokuvula ifeni | Imibandela yokufakwa |
|---|---|
| Ukuhluleka kwe-DTOZH noma ukulimala kwezintambo zayo | Iqale injini yomlilo yangaphakathi kumodi yesimo esiphuthumayo |
| Ukunqamula izintambo phansi | Isebenzisa injini yomlilo yangaphakathi, lapho othintana naye evela / enyamalala, isiphepheli singacisha |
| Isekhethi emfishane yezintambo ukuya “phansi” kuma-DTOZH amabili | Isebenzisa injini evuthayo yangaphakathi (inzwa yokuqala) noma ivuliwe (inzwa yesibili) |
| I-fan enephutha inika amandla ukudluliselwa | Iqale injini yomlilo yangaphakathi kumodi yesimo esiphuthumayo |
| "Amaphutha" ECU | Izindlela ezihlukene, kuncike ku-ECU ethile |
| Ukuchithwa kokushisa kwe-radiator kuyaphazamiseka (ukungcola) | Njengoba injini isebenza, phakathi nohambo olude |
| Inzwa ye-freon pressure engalungile | Uma i-air conditioner ivuliwe |
| Ukusebenza okuphansi kwesistimu yokupholisa | Lapho injini isebenza |
Kungani i-fan yokupholisa iqhubeka nokusebenza
Uma injini yomlilo yangaphakathi isebenza njalo, kungase kube nezizathu ezingu-7 zalokhu.
Inzwa yokushisa epholile
- Ukuhluleka kwenzwa yezinga lokushisa elipholile noma ukulimala kwezintambo zayo. Uma ulwazi olungalungile lusuka ku-sensor luye ku-ECU (isignali elinganiselwe noma engaphansi, ukungabikho kwayo, isifunda esifushane), khona-ke amaphutha akhiqizwa ku-ECU, ngenxa yalokho iyunithi yokulawula ibeka injini yomlilo yangaphakathi kwimodi ephuthumayo, lapho umlandeli “ebhula” njalo ukuze kungabikho i-ICE eshisa kakhulu. Ukuze uqonde ukuthi lokhu ukuwohloka kahle, kuzokwenzeka ngokuqala okunzima kwenjini evuthayo yangaphakathi uma nayo ingafudunyeziwe.
- Izintambo ezifinyeziwe ziye phansi. Ngokuvamile ifeni ihlale isebenza uma inqamula intambo enegethivu. Kuye ngomklamo wenjini yomlilo yangaphakathi, lokhu kungaba ezindaweni ezahlukene. Uma i-motor design ihlinzeka ngama-DTOZH amabili, khona-ke uma "ukususa" kwenzwa yokuqala kuphuka, ifeni "izobhula" ngokuvutha kuvuliwe. Esimeni sokulimala kokufakwa kwezintambo ze-DTOZH yesibili, ifeni isebenza njalo lapho injini yomlilo yangaphakathi isebenza.
- I-fan enephutha inika amandla ukudluliselwa. Ezimotweni eziningi, amandla fan aqukethe "plus" kusukela edluliselwe kanye "minus" kusukela ECU ngokuya izinga lokushisa kusukela DTOZH. "Plus" inikezwa njalo, futhi "minus" lapho izinga lokushisa lokusebenza le-antifreeze lifinyelelwa.
- "Izingqinamba" zeyunithi yokulawula ye-elekthronikhi. Ngakolunye uhlangothi, ukusebenza okungalungile kwe-ECU kungabangelwa ukungasebenzi kahle kwesofthiwe yayo (isibonelo, ngemva kokukhanyisa) noma uma umswakama ungena ngaphakathi kwecala lawo. Njengomswakama, kungase kube khona i-banal antifreeze eyangena ku-ECU (efanele izimoto ze-Chevrolet Cruze, lapho i-antifreeze ingena e-ECU ngeshubhu lokushisa eliphukile, itholakala eduze kwe-ECU).
- Irediyetha engcolile. Lokhu kusebenza kukho kokubili i-radiator eyinhloko kanye nerediyetha ye-air conditioner. Kulokhu, ngokuvamile isiphephetha-moya sigijima njalo lapho isifudumezi-moya sivuliwe.
- Inzwa ye-Freon pressure ku-air conditioner. Uma ihluleka futhi kukhona ukuvuza kwesiqandisi, isistimu "ibona" ukuthi i-radiator ishisa ngokweqile futhi izama ukuyipholisa nge-fan ehlala ivuliwe. Kwabanye abashayeli bezimoto, uma i-air conditioner ivuliwe, ifeni yokupholisa ihlale isebenza. Eqinisweni, lokhu akufanele kube njalo, ngoba lokhu kubonisa noma i-radiator evalekile (engcolile), noma izinkinga nge-Freon pressure sensor (Freon leak).
- Ukusebenza okuphansi kwesistimu yokupholisa. Ukuphuka kungahlotshaniswa nezinga eliphansi lokupholisa, ukuvuza kwalo, i-thermostat engalungile, ukwehluleka kwephampu, ukucindezelwa kwekepisi ye-radiator noma ithangi lokunweba. Ngenkinga enjalo, fan ingase ingasebenzi njalo, kodwa isikhathi eside noma ivule njalo.
Okufanele ukwenze uma ifeni yokupholisa isebenza njalo
Uma i-fan yokupholisa injini yomlilo yangaphakathi isebenza njalo, kufanele ubheke ukuhlukaniswa ngokwenza izinyathelo ezimbalwa zokuxilonga. Ukuhlola kufanele kwenziwe ngokulandelana, ngokusekelwe ezimbangela okungenzeka kakhulu.
Ukuhlanza i-radiator
- Hlola amaphutha kumemori ye-ECU. Isibonelo, ikhodi yephutha u-p2185 ikhombisa ukuthi akukho “minus” ku-DTOZH, kanti ezinye eziningi (kusuka ku-p0115 kuye ku-p0119) zikhombisa okunye ukungasebenzi kahle kwesekethe kagesi.
- Hlola ubuqotho bezintambo. Ngokuya ngomklamo wemoto, izintambo zomuntu ngamunye ezihambisana ne-fan drive zingalimala (imvamisa ukufakwa kwe-insulation kuphelile), okubangela isifunda esifushane. Ngakho-ke, udinga nje ukuthola indawo lapho ucingo lonakaliswe khona. Lokhu kungenziwa ngokubuka noma nge-multimeter. Njengenketho, faka izinaliti ezimbili koxhumana nabo be-chip bese uzivala ndawonye. Uma izintambo ziqinile, i-ECU izonikeza iphutha lokushisisa kwemoto.
- Bheka i-DTOZH. Uma yonke into ihlelekile nge-wiring namandla okunikezwa kwamandla kwenzwa, khona-ke kufanelekile ukuhlola inzwa yokushisa epholile. Kanye nokuhlola inzwa ngokwayo, udinga futhi ukuhlola othintana nabo ku-chip yayo kanye nekhwalithi yokulungiswa kwe-chip (ukuthi i-eyelet / latch iphukile). Uma kunesidingo, hlanza othintana nabo ku-chip kusuka kuma-oxides.
- I-Relay kanye nesheke le-fuse. Hlola ukuthi amandla avela ku-relay kuya kufeni usebenzisa i-multimeter (ungathola inombolo yephinikhodi emdwebeni). Kunezikhathi lapho "inamathela", khona-ke udinga ukuyishintsha. Uma amandla engekho, hlola i-fuse.
- Ukuhlanza ama-radiator nezinhlelo zokupholisa. Uma i-radiator eyisisekelo noma i-radiator ye-air conditioner imbozwe udoti, idinga ukuhlanzwa. Ukuvinjwa kwe-radiator yenjini yomlilo yangaphakathi nakho kungakha ngaphakathi, khona-ke udinga ukuhlanza lonke uhlelo lokupholisa ngezindlela ezikhethekile. Noma qaqa i-radiator bese uyigeza ngokuhlukana.
- Hlola ukusebenza kwesistimu yokupholisa. Ifeni ingasebenza ngokuqhubekayo ngokusebenza kahle okuphansi kwesistimu yokupholisa nezinto zayo ngazinye. Ngakho-ke, kuhle ukuhlola uhlelo lokupholisa, futhi uma kutholakala ukuphuka, lungisa noma ubuyisele izingxenye zayo.
- Ihlola ileveli ye-freon kanye nokusebenza kwenzwa yokucindezela kwesiqandisi. Ukuze wenze lezi zinqubo futhi uqede imbangela, kungcono ukuvakashela isevisi.
- Shintshanisa amasheya ECU kuyindlela yokugcina lapho wonke amanye amanodi esehloliwe. Ngokuvamile, iyunithi yokulawula kufanele ihlakazwe futhi izindlu zayo zihlakazwe. bese uhlola isimo sebhodi langaphakathi kanye nezakhi zalo, uma kunesidingo, lihlanze ngotshwala kusuka ku-antifreeze kanye nemfucumfucu.
Ehlobo, ukushayela nefeni njalo akuthandeki, kodwa kuyamukeleka. Kodwa-ke, uma i-fan iphenduka njalo ebusika, kunconywa ukuxilonga nokulungisa ukuphuka ngokushesha ngangokunokwenzeka.
isiphetho
Ngokuvamile, i-radiator yokupholisa i-fan iphenduka njalo ngenxa yesifunda esifushane ku-relay yokuqala noma izintambo zayo. Ezinye izinkinga azivamile. Ngakho-ke, ukuxilonga kufanele kuqale ngokubheka i-relay, izintambo kanye nokuba khona kwamaphutha kumemori yekhompyutha.
