Mfundo yogwirira ntchito ya jenereta yamagalimoto, momwe jenereta imagwirira ntchito
Mfundo yogwirira ntchito ya jenereta yamagalimoto imachokera ku lamulo la kulowetsa mphamvu zamagetsi. Ntchito yake yayikulu ndikusintha mphamvu yamakina ya injini kukhala mphamvu zamagetsi, kupereka mphamvu zamagetsi zamagalimoto ndikuchaja batri. Nayi kufotokozera mwatsatanetsatane kwa momwe imagwirira ntchito:
Momwe jenereta imagwirira ntchito
Gwero la mphamvu ndi kusonkhezera koyamba: Injini ikagwira ntchito, imayendetsedwa ndi lamba kuti izungulire rotor ya jenereta. Pa gawo loyamba la jenereta, batire imapereka mphamvu ku zozungulira zosonkhezera pa rotor, ndikuyika maginito pamizere ya claw ya rotor mumizere ya N ndi S, motero imapanga mphamvu ya maginito.
Kulowetsa kwa maginito kumapangira mphamvu yosinthira: Pamene rotor ikuzungulira mofulumira mkati mwa ma stator windings, mphamvu yamaginito yozungulira iyi imadula nthawi zonse kudzera mu ma three-phase windings mu stator. Malinga ndi mfundo ya electromagnetic induction, mphamvu ya electromotive yomwe imayambitsidwa ndi magawo atatu (monga, alternating current) idzapangidwa mu ma stator windings.
Kukonzanso: Kusinthana kwa mphamvu yamagetsi kupita ku mphamvu yamagetsi yolunjika: Mphamvu yamagetsi yosinthika yopangidwa ndi stator singathe kupereka mphamvu mwachindunji ku dongosolo lamagetsi la DC la galimoto (monga magetsi, mawu, ECU, ndi zina zotero) ndi batire. Chifukwa chake, mphamvu yamagetsi yosinthasintha imalowa mu rectifier (nthawi zambiri dera lokonzanso mlatho la magawo atatu lopangidwa ndi ma diode asanu ndi limodzi kapena kuposerapo), limasanduka mphamvu yamagetsi yolunjika.
Kulamulira mphamvu yamagetsi ndi kutulutsa kokhazikika: Chowongolera mphamvu yamagetsi ndiye "ubongo" wa jenereta. Chimayang'anira mphamvu yamagetsi yotuluka ya jenereta nthawi zonse. Liwiro la injini likasintha zomwe zimapangitsa kusinthasintha kwa mphamvu yamagetsi yotuluka, chowongolera chimasintha mphamvu ya mphamvu yamagetsi powongolera kukula kwa mphamvu yamagetsi, ndikuwonetsetsa kuti mphamvu yamagetsi yotuluka nthawi zonse imakhala yokhazikika mkati mwa 13.5V mpaka 14.5V, kuteteza zida zamagetsi zagalimoto.
Kudzidalira ndi kutchaja: Pamene mphamvu yotulutsa ya jenereta ikukwera kuti ikhale yofanana ndi mphamvu ya batri, kuwala kowonetsa kutchaja kudzazimitsidwa. Pa nthawiyi, mphamvu yotulutsa siiperekedwanso ndi batri koma ndi jenereta yokha, kulowa mu mkhalidwe wabwinobwino wogwirira ntchito. Pamapeto pake, mphamvu yolunjika yopangidwayo imapereka mphamvu ku zida zonse zamagetsi zamagalimoto ndikuchaja batri, kuonetsetsa kuti mphamvu yokwanira ikuyambanso.
Mgwirizano wa zigawo zazikulu
Rotor: Imapanga mphamvu ya maginito yozungulira, kukhala "gawo logwira ntchito" la induction ya maginito.
Stator: Ili ndi ma windings a magawo atatu, omwe ndi "phati lapadera" lomwe limadula mizere ya mphamvu ya maginito kuti ipange mphamvu yamagetsi.
Chosinthira: "Chosinthira" cha kiyi, chomwe chimasintha mphamvu yosinthira kukhala mphamvu yolunjika.
Chowongolera magetsi: Chofunikira kwambiri ndi "stabilizer", chomwe chimatsimikizira kuti magetsi azikhala nthawi zonse.
Mphete ya burashi ndi yotsetsereka: Imayambitsa magetsi ku ma windings ozungulira a rotor excitation (mu majenereta achikhalidwe a excitation).
Mwachidule, jenereta yamagalimoto ndi njira yeniyeni yosinthira mphamvu yamakina ndi magetsi, ndipo gawo lililonse limagwira ntchito mogwirizana kuti litsimikizire kuti magetsi agalimoto ali okhazikika komanso odalirika pamikhalidwe yosiyanasiyana.
Pali zizindikiro zosiyanasiyana pamene jenereta yawonongeka, makamaka kuphatikizapo: nyali yochenjeza ya dashboard imayatsidwa, nyali zimazimiririka, zovuta kuyatsa, zida zamagetsi zosazolowereka, phokoso kapena fungo losazolowereka, ndi zina zotero.
Nyali yowunikira pa dashboard imakhala yoyatsidwa nthawi zonse: Galimoto ikayamba, nyali yowunikira pa dashboard (chithunzi cha batri kapena chizindikiro cha ALT/GEN) imakhalabe yoyatsidwa kapena yowala, kusonyeza vuto mu dongosolo lowunikira.
Kuwala kwa nyali za magetsi ndi nyali za dashboard: Chifukwa cha magetsi osakwanira, nyali za magetsi ndi nyali za dashboard zimazimiririka kapena kusintha ndi accelerator pedal. Izi zimaonekera kwambiri poyendetsa galimoto usiku.
Kuvuta kuyambitsa kapena kulephera kuyambitsa: Pamene jenereta sipanga magetsi, batire limatha, zomwe zimapangitsa kuti kuyatsa kukhale kovuta kapena kulephera kuyatsa, komanso kulephera kuyatsanso injini ikazima.
Kuchepa kwa batri mosalekeza: Ngakhale mutachaja, mphamvu ya batri imachepa mwachangu, zomwe zimaonekera ngati kuvutika kuyambitsa kapena batri yatsopano kubwerera ku kuchepa nthawi yomweyo ikangosinthidwa.
Kugwira ntchito molakwika kwa zida zamagetsi: Mawindo amagetsi, mipando, mpweya woziziritsa, chophimba chowongolera chapakati, ndi zina zotero, zimagwira ntchito pang'onopang'ono, kuchedwa, kapena kulephera chifukwa cha mphamvu yosakhazikika yamagetsi.
Phokoso kapena fungo losazolowereka: Pamene lamba wa jenereta watsika, pamakhala fungo la rabara loyaka; Ma bearing amkati amatha ndipo amapanga phokoso la "kugwedezeka" kapena "kulira".
Kugwira ntchito kwa injini sikukhazikika: Mphamvu yochepa yotulutsa mphamvu kuchokera ku jenereta ingayambitse kugwedezeka kwa injini ndikukhala ndi liwiro losakhazikika losakhazikika, motero kukhudza mphamvu yotulutsa mphamvu.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
