Momwe jenereta yamagalimoto imagwirira ntchito
Mfundo yaikulu yogwirira ntchito ya jenereta yamagalimoto imachokera ku lamulo la kulowetsa magetsi mumagetsi. Mphamvu yosinthira imapangidwa ndi kayendedwe ka rotor ndi stator, kenako imasinthidwa kukhala mphamvu yolunjika pogwiritsa ntchito chosinthira magetsi kuti galimoto igwiritse ntchito.
Njira yeniyeni yogwirira ntchito ingagawidwe m'magawo otsatirawa:
Kusintha kwa mphamvu ndi kukhazikitsidwa kwa mphamvu ya maginito
Injini imayendetsa jenereta yozungulira kudzera mu lamba kuti izungulire (kulowetsa mphamvu yamakina), ndipo zozungulira zosangalatsa pa rotor zimapanga mphamvu ya maginito pambuyo poti yapatsidwa mphamvu (N pole ndi S pole zimagawidwa mosiyanasiyana).
Pa gawo loyamba (pa liwiro lotsika), batire imapereka mphamvu yotulutsa mphamvu (njira yosiyana yotulutsira mphamvu) kuti zitsimikizire kuti mphamvu ya maginito yakhazikika.
Kupanga kwa induction ya ma electromagnetic
Rotor ikazungulira, mphamvu yake ya maginito imayenda poyerekeza ndi stator winding, ndipo mzere wa maginito wa inductance mu stator winding umadulidwa kuti upange alternating current ya magawo atatu.
Ma windings a stator amagawidwa pa ngodya yamagetsi ya madigiri 120, zomwe zimapangitsa kuti AC ya magawo atatu ikhale yofanana.
Chokonzanso ndi chotulutsa
Mphamvu yosinthira ya stator imasinthidwa kukhala mphamvu yolunjika kudzera mu mlatho wokonzanso (nthawi zambiri umakhala ndi machubu 6 kapena 9) wopangidwa ndi ma diode, omwe amagwiritsidwa ntchito ndi zida zamagalimoto ndikuchaja batri.
Ma rectifier apangidwa kuti atsimikizire kuti magetsi akuyenda bwino, monga jenereta ya nine-tube yomwe imakonza lupu yotsitsimula ndi ma diode ena.
Kulamulira kwa Voltage ndi Kulamulira Kukhazikika
Chowongolera magetsi chimasintha mphamvu yamagetsi molingana ndi momwe batire ilili komanso kuchuluka kwa mphamvu zomwe zimafunika, ndipo chimasunga mphamvu yamagetsi yotuluka pakati pa 13.8-14.8V.
Liwiro la jenereta likakwera mokwanira (gawo lodzipangitsa kudzikuza) ndipo mphamvu yotulutsa ikagwirizana ndi mphamvu ya batri, chizindikiro chochaja chimazimitsidwa, kusonyeza kuti makinawo akugwira ntchito bwino.
Kukulitsa ukadaulo: Majenereta amakono a magalimoto nthawi zambiri amaphatikiza gawo lanzeru lolamulira, kuphatikiza ndi CAN bus kuti akwaniritse kugwiritsa ntchito bwino mphamvu. Kapangidwe kake kayenera kulinganiza bwino kupanga mphamvu mwachangu komanso magwiridwe antchito a kutentha m'malo otentha kwambiri, ndipo mitundu ina imagwiritsa ntchito ma alternator opanda burashi kuti ichepetse zosowa zosamalira.
Voliyumu yogwira ntchito ya jenereta ya galimoto nthawi zambiri imakhala pakati pa ma volts 13.5-14.5, mtengo wake umasinthidwa molingana ndi momwe chowongolera magetsi chimakhalira komanso liwiro la injini.
Chiganizo chachikulu
Mtundu wa voltage wamba
Mphamvu yamagetsi yotulutsa jenereta ya magalimoto ambiri onyamula anthu (makina a 12V) ndi yokhazikika pa 13.5-14.5 volts, yomwe ndi mphamvu yotetezeka ya mphamvu yamagetsi yoyandama ya batire, yomwe ingatsimikizire kuti zida zamagetsi zikugwira ntchito komanso kupewa kudzaza kwambiri.
Pazifukwa zapadera (monga pambuyo pozizira), pakhoza kukhala kusinthasintha kwakanthawi kwa ma volts 12.6-14.5, koma sizachilendo ngati ikupitiliza kupitirira malire awa.
Zotsatira za voteji yosadziwika bwino
pansi pa 13 volts: Batire ili ndi mphamvu yokwanira, zomwe zingayambitse vuto poyambitsa kapena kusakhazikika kwa magetsi ku chipangizo chamagetsi
Ma volts opitilira 14.5: imathandizira kutuluka kwa electrolyte ya batri, kufupikitsa moyo wa batri ya lead-acid, ndipo imatha kuyatsa zida zamagetsi
Malangizo a mayeso
Gwiritsani ntchito multimeter kuti muyese mphamvu ya magetsi yotulutsa mphamvu ya jenereta. Injini ikayamba, isungeni pa 2000 RPM. Chipangizo chamagetsi chagalimoto chikazimitsidwa, mphamvu ya magetsi iyenera kukhala yokhazikika pa 14.2±0.3 volts.
Ngati magetsi sakuyenda bwino, yang'anani chosinthira magetsi, chowongolera magetsi, ndi mphamvu ya lamba
Zindikirani: "Ma volti 17-15" ndi deta ina yomwe yatchulidwa mu zotsatira zakusaka sizikugwirizana, ndipo pambuyo potsimikizira, zapezeka kuti zimachokera ku njira zotsika mtengo ndipo sizikugwirizana ndi miyezo yayikulu yosamalira magalimoto, kotero sizigwiritsidwa ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
