Mfundo yogwirira ntchito ya mafani amagetsi agalimoto
Fani yamagetsi yamagalimoto imayang'anira kutentha kwa injini yokha kudzera mu njira yanzeru yowongolera kutentha, kuonetsetsa kuti ikugwira ntchito bwino kwambiri.
Kufotokozera Mfundo Yogwirira Ntchito
Kuzindikira Kutentha ndi Kulamulira Koyambira/Kuyimitsa
Zigawo zazikulu zowongolera za fan yamagetsi ndi chowongolera kutentha (kapena sensa ya kutentha kwa madzi) ndi ECU ya injini (Electronic Control Unit). Kutentha kwa coolant ya injini kukakwera kufika pamlingo wapamwamba wokhazikitsidwa (nthawi zambiri 92°C - 105°C), chowongolera kutentha chimayatsa magetsi ndipo fan imayamba kuziziritsa mwamphamvu. Kutentha kukatsika kufika pamlingo wotetezeka (monga 88°C - 93°C), chowongolera kutentha chimadula magetsi ndipo fan imayima yokha kuti ipewe kuziziritsa kwambiri komwe kungasokoneze magwiridwe antchito a injini.
Njira Yowongolera Liwiro la Magawo Ambiri
Mafani ambiri amagetsi ali ndi njira ziwiri kapena zambiri zothamanga:
Madzi akafika kutentha kwa pafupifupi 90°C, faniyo imagwira ntchito mofulumira kwambiri;
Kutentha kukakwera pamwamba pa 95°C, kumasinthira ku ntchito yachangu kwambiri kuti kuwonjezere mphamvu yoziziritsira.
Lamuloli nthawi zambiri limakwaniritsidwa ndi switch ya kutentha yomwe imazindikira kutentha kwa madzi ndikutumiza chizindikiro ku unit yowongolera J293, yomwe imagwiritsa ntchito dalaivala wa dera kusintha kayendedwe ka ntchito kapena chizindikiro cha PWM kuti chiwongolere liwiro.
Kuwongolera Kogwirizana kwa Air Conditioning System
Ngakhale kutentha kwa madzi sikunafike pamlingo wapamwamba, kuyambitsa choziziritsira mpweya kudzayambitsa fani kuti igwire ntchito. Chifukwa choziziritsira mpweya chiyenera kutulutsa kutentha kuti chiziziziritse, kompyuta yoziziritsira mpweya (J301) idzatumiza chizindikiro choyambitsa mwamphamvu ku chipangizo chowongolera fani (J293), zomwe zimapangitsa fani kugwira ntchito mogwirizana. Izi zimatsimikizira kuti choziziritsira mpweya chikugwira ntchito bwino komanso kupewa kuti injini isatenthe kwambiri.
Kuchedwa Kuziziritsa Injini Ikatha Kuzimitsidwa
Magalimoto ena ali ndi mawonekedwe a "kuchedwa kuziziritsa": Injini ikazima, ngati kutentha kwa choziziritsira kumakhalabe pamwamba pa mtengo winawake (monga 117°C), faniyo ipitiliza kugwira ntchito kwa mphindi zingapo mpaka kutentha kutsika kufika pamlingo wabwino kuti ipewe "kuchulukana kwa kutentha" ndi zina zolephera.
Chitetezo cha Zolakwika ndi Kuwunika kwa Dongosolo
Makina amakono amagetsi oyendera magetsi ali ndi njira zodzitetezera, kuphatikizapo kuyang'anira nthawi yeniyeni mphamvu ya injini, magetsi, ndi liwiro. Ngati pali mavuto ena monga overvoltage, overcurrent, short circuit, kapena motor jamming, makina owongolera amachotsa chitetezo chozimitsa magetsi kuti apewe kuwonongeka kwa makina onse oziziritsira.
Kuyerekeza ndi Mitundu Ina ya Fan
Fan yamagetsi vs Fan yamafuta a Silicone Clutch
Fani yamagetsi imayendetsedwa bwino ndi ECU, imagwira ntchito mwachangu komanso bwino kwambiri, yoyenera machitidwe amakono oyendetsera kutentha; pomwe fani yamafuta a silicone imayendetsedwa ndi mphamvu yeniyeni ya kukulitsa kutentha kwamafuta a silicone, yokhala ndi kapangidwe kosavuta koma kulondola kochepa.
Fan yamagetsi vs Fan yamakina yachikhalidwe
Mafani achikhalidwe amakina amayendetsedwa mwachindunji ndi lamba wa injini ndipo nthawi zonse amagwira ntchito; amagwiritsa ntchito mphamvu zambiri; pomwe fan yamagetsi imayamba ndikuyima ngati pakufunika, zomwe zimachepetsa kwambiri kutayika kwa mphamvu ndikuchepetsa kugwiritsa ntchito mafuta.
Kuweruza ngati fan yamagetsi yamagalimoto ikugwira ntchito bwino kungachitike kudzera m'mbali zosiyanasiyana monga kuwona momwe ikugwira ntchito, kumvetsera phokoso, kuzindikira kusintha kwa kutentha, ndikuwona zinthu zina zokhudzana nazo.
Njira Yowonera Mwanzeru
Onani ngati fan ikuzungulira
Yatsani injini ndipo dikirani kuti kutentha kwa madzi kukwere pamwamba pa 80°C (pafupifupi mphindi 5-10), kenako tsegulani hood ndikuwona ngati fani ya radiator ikuyamba yokha. Kawirikawiri, kutentha kwa madzi kukafika pa 90–98°C, faniyo iyenera kuyamba ndi liwiro lotsika; ngati kutentha kukupitirira kukwera (monga pamwamba pa 102°C), idzasinthira ku liwiro lapamwamba.
Onani Ntchito Yogwirizana ndi Air Conditioning
Yatsani njira yoziziritsira mpweya woziziritsa, ngakhale kutentha kwa madzi kutakhala kochepa, fani iyeneranso kuyamba kuthandiza condenser kuziziritsa. Ngati faniyo siyankha mutayatsa faniyo, pakhoza kukhala vuto mu dera lowongolera kapena relay.
Chiweruzo Chothandizira Kumva ndi Kugwira
Mvetserani phokoso la ntchito
Fani imagwira ntchito ndi phokoso lofanana la "kuzungulira". Ngati pali phokoso losazolowereka "logundana" kapena phokoso lakuthwa la kukangana, mwina chifukwa cha kusintha kwa tsamba, kuwonongeka kwa mabearing, kapena kulephera kwa injini.
Mukakhala otetezeka, mukayandikira kumbuyo kwa fan (koma osakhudza masamba), muyenera kumva bwino momwe air imayendera. Ngati palibe mphepo kapena mphepo ndi yofooka, izi zingasonyeze kuti injini siili bwino kapena kuti ma fan blade ake ndi omangika.
Kuwunika kutentha ndi zida
Yang'anirani kutentha kwa madzi: Ngati kutentha kwa madzi kukupitirirabe (cholozera chili pafupi ndi malo ofiira) ndipo fani siikuyaka, zimasonyeza kuti faniyo sikugwira ntchito momwe ikufunira.
Ngati fani ikupitiriza kugwira ntchito kwa mphindi zingapo injini itazimitsidwa, ndi ntchito yachibadwa yoziziritsa mochedwa; koma ngati siimayima kuzungulira kwa nthawi yayitali, ikhoza kukhala vuto mu switch yowongolera kutentha kapena module yowongolera.
Kuyang'anira zigawo zazikulu
Yang'anani ma fuse ndi ma relay
Pezani bokosi la fuse m'chipinda cha injini, tsimikizirani ngati fuse yofanana ndi fan yaphulika, komanso ngati relay ikugwira ntchito bwino. Mutha kuyesa momwe relay imagwirira ntchito posintha.
Yesani injini ndi mawaya
Chotsani pulagi ya fan ndikulumikiza mwachindunji gwero lamagetsi la 12V. Faniyo iyenera kukhala yokhoza kuzungulira bwino ndipo sipayenera kukhala phokoso losazolowereka. Kupanda kutero, motayo imawonongeka.
Gwiritsani ntchito multimeter kuti muyese kukana kwa mota. Ngati kukanako kuli kosazolowereka (kokwera kwambiri kapena kosatha), zimasonyeza vuto la mkati mwa injini.
Kuthetsa mavuto ndi masensa owongolera kutentha
Kulephera kwa sensa ya kutentha kwa madzi kapena switch ya kutentha kudzapangitsa kuti fan isalandire chizindikiro choyambira. Mutha kuwerenga deta ya kutentha kwa madzi pogwiritsa ntchito chida chowunikira kapena kuyesa kutentha kwa switch yowongolera kutentha m'madzi otentha (nthawi zambiri 93–98°C ndi yoyendetsa).
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
