Ungayihlola kanjani inzwa yefeni
Okuqukethwe
Umbuzo wakho indlela yokuhlola inzwa yabalandeli, abanikazi bezimoto bangase babe nesithakazelo lapho i-fan yokupholisa irediyetha yenjini evuthayo yangaphakathi ingavuli noma, ngokuphambene, isebenza njalo. Futhi konke ngoba ngokuvamile lesi sici siyimbangela yenkinga enjalo. ukuze uhlole inzwa yokuvula i-fan yokupholisa, udinga ukwazi isimiso sokusebenza kwayo, futhi kufanele usebenzise i-multimeter ukuthatha izilinganiso ezithile.
Ngaphambi kokuqhubeka encazelweni yenqubo yokuhlola inzwa yokushintsha i-radiator fan, kufanelekile ukuqonda ukuthi isebenza kanjani kanye nezinhlobo zayo eziyisisekelo zokungasebenzi kahle.
Indlela inzwa yefeni esebenza ngayo
I-fan switch ngokwayo iyi-relay yezinga lokushisa. Ukuklama kwayo kusekelwe epuleti le-bimetallic elixhunywe kwintonga ehambayo. Lapho isici esibucayi senzwa sishisiswa, ipuleti le-bimetallic liyagoba, futhi induku exhunywe kuyo ivala umjikelezo kagesi we-cooling fan drive.
Isici esibucayi sihlangana ne-antifreeze, imvamisa kurediyetha (engxenyeni yayo engezansi, eceleni, kuye ngemodeli yemoto), kodwa kukhona amamodeli e-ICE lapho inzwa yabalandeli ibekwe ku-cylinder block, njengaku- imoto edumile ye-VAZ-2110 (kuma-ICEs womjovo). Futhi ngezinye izikhathi ukuklanywa kwezinye izinjini ezivuthayo zangaphakathi kunikeza izinzwa eziningi ezifika ezimbili zokuvula isiphephetha-moya, okungukuthi, amapayipi okungena nokuphuma kwe-radiator. Lokhu kukuvumela ukuthi uvule futhi uvale ifeni ngenkani lapho izinga lokushisa le-antifreeze lehla.
Kuyafaneleka futhi ukwazi ukuthi kunezinhlobo ezimbili zenzwa yokushisa yabalandeli - izikhonkwane ezimbili nezikhonkwane ezintathu. Izikhonkwane ezimbili zenzelwe ukusebenza kwabalandeli ngesivinini esisodwa, futhi izikhonkwane ezintathu zenzelwe isivinini sabalandeli ababili. Isivinini sokuqala sishintshwa ekushiseni okuphansi (isibonelo, ku-+92 ° С…+95 ° С), kanti okwesibili - ekushiseni okuphezulu (isibonelo, ku-+102 ° С…105С °).
ukwehluleka kwenzwa yokushintsha abalandeli
Inzwa yokuvula ifeni epholisayo iyidivayisi elula, ngakho-ke inezimbangela ezimbalwa zokuphuka. Kungase kungasebenzi ezimweni ezinjalo:
Izixhumi ku-chip ye-DVV enamaphini amathathu
- Othintana naye uyanamathela. Kulokhu, fan izosebenza njalo, kungakhathaliseki izinga lokushisa le-antifreeze.
- Xhumana ne-oxidation. Kulokhu, ifeni ngeke ivule nhlobo.
- Ukuphuka kwe-relay (induku).
- Ukugqokwa kwepuleti le-bimetallic.
- Awekho amandla e-fuse.
Sicela uqaphele ukuthi inzwa yokushintsha abalandeli ayinakuhlukaniswa futhi ayikwazi ukulungiswa, ngakho-ke, uma kutholwa ukwehluleka, kuyashintshwa. Emotweni yesimanje, ukukhanya kwenjini yesheke kuzobonisa inkinga, ngoba iphutha elilodwa noma amaningi alandelayo azorekhodwa kumemori ye-electronic control unit (ECU) - p0526, p0527, p0528, p0529. Lawa makhodi wephutha azobika isifunda esivulekile, kokubili isignali namandla, kodwa lokhu kwenzeke ngenxa yokwehluleka kwezinzwa noma izinkinga zezintambo noma zokuxhuma - ungathola kuphela ngemva kokuhlola.
Ungayihlola kanjani inzwa yefeni
ukuze uhlole ukusebenza kwenzwa yokuvula i-fan, kufanele ihlakazwe esihlalweni sayo. Njengoba kushiwo ngenhla, ngokuvamile itholakala ku-radiator noma ku-cylinder block. Kodwa-ke, ngaphambi kokudiliza nokuhlola inzwa, udinga ukwenza isiqiniseko sokuthi amandla anikezwa kuyo.
Ukuhlola amandla
I-DVV Power Check
Ku-multimeter, sivula imodi yokulinganisa i-voltage ye-DC ngaphakathi kwebanga elingama-Volts angama-20 (kuye ngokuthi imodeli ethile ye-multimeter). Ku-chip yenzwa enqanyuliwe, udinga ukuhlola i-voltage. Uma inzwa inamaphini amabili, uzobona ngokushesha ukuthi kukhona ama-volts angu-12 lapho. Ku-sensor yokuxhumana abathathu, kufanele uhlole i-voltage phakathi kwezikhonkwane ku-chip ngamabili ukuze uthole lapho kukhona "i-plus" eyodwa nalapho kukhona "ama-minuses" amabili. Phakathi kwe-"plus" kanye "nokukhipha" ngakunye kumele kube ne-voltage engu-12V.
Uma kungekho mandla ku-chip, okokuqala udinga ukuhlola ukuthi i-fuse iphelele yini (ingaba kokubili ku-block ngaphansi kwe-hood kanye nendawo yabagibeli yemoto). Indawo yayo ivame ukukhonjiswa kukhava yebhokisi le-fuse. Uma i-fuse iphelele, udinga "ukukhalisa" i-wiring futhi uhlole i-chip. Khona-ke kufanelekile ukuqala ukuhlola inzwa yabalandeli ngokwayo.
Kodwa-ke, ngaphambi kokukhipha i-antifreeze futhi ukhulule inzwa yokupholisa i-radiator, kufanelekile ukwenza ukuhlolwa okuncane okuzokwenza isiqiniseko sokuthi isiphephelo sisebenza kahle.
Ihlola ukusebenza kwefeni
Ngosizo lwanoma iyiphi i-jumper (ucezu locingo oluncane), vala "plus" ngamabili kanye neyokuqala, bese kuthi "minus" yesibili. Uma i-wiring iqinile, futhi i-fan isebenza, khona-ke ngesikhathi sokujikeleza, eyokuqala bese kuthi ijubane le-fan yesibili livule. Kunzwa yokuxhumana ababili, isivinini sizoba esisodwa.
kuyafaneleka futhi ukuhlola ukuthi ngabe fan ivaliwe yini lapho inzwa ivaliwe, uma othintana nabo benamathele kuyo. Uma, lapho inzwa ivaliwe, fan iyaqhubeka nokusebenza, khona-ke lokhu kusho ukuthi kukhona okungalungile ngenzwa, futhi idinga ukuhlolwa. Ukuze wenze lokhu, inzwa kufanele isuswe emotweni.
Ukuhlola inzwa yokushintsha ifeni
Ungahlola i-DVV ngezindlela ezimbili - ngokuyifudumeza emanzini afudumele, noma ungayishisisa ngensimbi yokunamathisela. Zombili zisho ukuhlola ukuqhubeka. Kuphela esimweni sokugcina, uzodinga i-multimeter ene-thermocouple, futhi esimweni sokuqala, i-thermometer ekwazi ukulinganisa amazinga okushisa angaphezu kuka-100 degrees Celsius. Uma inzwa yokuvula i-fan-contact emithathu ihlolwe, enezivinini ezimbili zokushintsha (efakwe ezimotweni eziningi zangaphandle), ngakho-ke kuhle ukusebenzisa ama-multimeters amabili ngesikhathi esisodwa. Enye iwukuhlola isifunda esisodwa, kanti eyesibili iwukuhlola ngesikhathi esisodwa isifunda sesibili. Ingqikithi yokuhlolwa ukuthola ukuthi i-relay icushiwe yini lapho ishiselwa ezingeni lokushisa elikhonjiswe kunzwa.
Babheka inzwa yokuvula i-radiator yokupholisa fan ngokuya nge-algorithm elandelayo (besebenzisa isibonelo senzwa yamaphini amathathu kanye ne-multimeter eyodwa, kanye ne-multimeter ene-thermocouple):
Ukuhlola i-DVV emanzini afudumele nge-multimeter
- Setha i-multimeter ye-elekthronikhi kumodi "yokudayela".
- Xhuma i-probe ebomvu ye-multimeter ekuxhumaneni okuhle kwenzwa, futhi okumnyama kuye ku-minus, obhekene nesivinini se-fan ephansi.
- Xhuma i-probe ekala izinga lokushisa endaweni yento ebucayi yenzwa.
- Vula i-ayini yokunamathisela bese unamathisele ithiphu yayo engxenyeni ebucayi yenzwa.
- Lapho izinga lokushisa lepuleti le-bimetallic lifinyelela inani elibalulekile (elikhonjiswe ku-sensor), inzwa yokusebenza izovala isifunda, futhi i-multimeter izobonisa lokhu (kwimodi yokudayela, i-multimeter beep).
- Hambisa i-probe emnyama kokuthi "minus", okuyiyona enesibopho sejubane labalandeli besibili.
- Njengoba ukushisa kuqhubeka, ngemva kwemizuzwana embalwa, inzwa yokusebenza kufanele ivale futhi isifunda sesibili, lapho izinga lokushisa lomkhawulo lifinyelelwa, i-multimeter izokhala futhi.
- Ngakho-ke, uma inzwa ingavali isifunda sayo ngesikhathi sokufudumala, inephutha.
Ukuhlola inzwa yokuxhumana ababili kwenziwa ngokufanayo, ukumelana kuphela okudinga ukukalwa phakathi kwepheya elilodwa labathintwayo.
Uma inzwa ingashisi nge-iron soldering, kodwa esitsheni esinamanzi, qiniseka ukuthi akuyona yonke inzwa ehlanganisiwe, kodwa isici sayo esibucayi kuphela! Njengoba ishisa (ukulawula kwenziwa nge-thermometer), ukusebenza okufanayo kuzokwenzeka njengoba kuchazwe ngenhla.
isiphetho
Inzwa yokupholisa i-fan switch iyisisetshenziswa esinokwethenjelwa, kodwa uma kukhona ukusola ukuthi ihlulekile, khona-ke ukuyihlola, udinga i-multimeter, i-thermometer kanye nomthombo wokushisa ozoshisa into ebucayi.
