Gulu loyambira
1. Alternator voltage regulator ingagawidwe: molingana ndi mfundo yogwirira ntchito:
(1) Lumikizanani ndi chowongolera magetsi
Kulumikizana kwamagetsi owongolera kumagwiritsidwa ntchito kale, ma frequency owongolera awa amachedwa pang'onopang'ono, pali inertia yamakina ndi ma electromagnetic inertia, kulondola kwamagetsi otsika, kulumikizana kosavuta kutulutsa zipsera, kusokoneza kwakukulu kwa wailesi, kudalirika kosadalirika, moyo waufupi, zathetsedwa.
(2) Transistor regulator
Ndi chitukuko chaukadaulo wa semiconductor, owongolera ma transistor adalandiridwa.Ubwino wake ndi: ma transistor kusintha pafupipafupi ndi okwera, ndipo samatulutsa zipsera, kulondola kwakukulu kosintha, komanso ali ndi ubwino wa kulemera kwa kuwala, kukula kochepa, moyo wautali, kudalirika kwakukulu, kusokoneza kwa wailesi yaing'ono, etc., ndipo tsopano ndi ambiri. amagwiritsidwa ntchito ku Dongfeng, Jiefang ndi mitundu yosiyanasiyana yotsika.
3) Integrated circuit regulator
Kuphatikiza pa zabwino za owongolera ma transistor, owongolera madera ophatikizika amakhalanso ang'ono-zing'ono, okwera mkati mwa jenereta (omwe amadziwikanso kuti owongolera omangidwa), amachepetsa mawaya akunja, komanso kuzizira kwasinthidwa, ndipo tsopano akugwiritsidwa ntchito kwambiri Santana.Audi ndi mitundu ina ya sedan.
(4) Woyang'anira makompyuta
Pambuyo kuyeza kuchuluka kwa dongosolo ndi chowunikira chamagetsi, chizindikirocho chimatumizidwa ku kompyuta ya jenereta, ndiyeno jenereta yowongolera magetsi imayendetsedwa ndi kompyuta ya injini, ndipo gawo la maginito limayatsidwa ndikuzimitsa munthawi yake. , ndiko kuti, ntchito yachibadwa ya magetsi ikhoza kutsimikiziridwa modalirika, batire ikhoza kulipiritsidwa mokwanira, ndipo kuchuluka kwa injini kungathe kuchepetsedwa ndipo chuma chamafuta chikhoza kusintha.Mwachitsanzo, Shanghai Buick, Guangzhou Honda ndi majenereta ena amagalimoto amagwiritsa ntchito chowongolera ichi.
2. Voltage regulator
Malingana ndi mtundu wachitsulo wa alternator ukhoza kugawidwa mu:
(1) Wowongolera mtundu wachitsulo wamkati
Chowongolera chamagetsi choyenera kufananiza ndi chosinthira chamtundu wa tayi chamkati chimatchedwa chowongolera chamtundu wamkati;
(2) Wowongolera mtundu wachitsulo wakunja
Voltage regulator yoyenera kufanana ndi alternator yakunja ya tayi imatchedwa outer tie-iron regulator.
Pogwiritsira ntchito, kwa transistor regulator, ndi bwino kugwiritsa ntchito chowongolera chomwe chimatchulidwa m'buku la galimoto, ngati zitsanzo zina zimagwiritsidwa ntchito m'malo, kuwonjezera pa voliyumu yadzina ndi magawo ena otchulidwa ndi wolamulira woyambirira ndi yemweyo, chowongolera choloŵa m'malo chiyenera kukhala chofanana ndi mawonekedwe achitsulo choyambirira, apo ayi, jenereta silingagwire ntchito bwino chifukwa cha dera losangalatsa.Kwa olamulira ozungulira ophatikizika, ayenera kudzipereka ndipo sangathe kusinthidwa.
Gwiritsani ntchito kukonza
Gwiritsani ntchito kukonza
Woyang'anira nthawi zambiri saloledwa kusokoneza chivundikirochi akamagwiritsidwa ntchito, ndipo zomwe zikuchitika ndikuwunika ndikukonza 200h iliyonse kapena kupitilira apo, ndipo zomwe zilimo ndi izi:
1.Chotsani mlanduwo ndikuyang'ana malo okhudzana ndi dothi ndikuwotcha.Ngati pali dothi, pukutani ndi pepala loyeretsa.Ngati kukhudzana kwachotsedwa kapena kusagwirizana ndipo kukhudzana kwake kuli koyipa, nthawi zambiri kumakonzedwa ndi sandpaper kapena mchenga "00", ndipo pamapeto pake amapukutidwa ndi pepala loyera.
2.Fufuzani kulimba kwa cholumikizira chilichonse, yesani kukana ndi kukana kwa koyilo iliyonse.Ngati pali zowonongeka, ziyenera kukonzedwa kapena kusinthidwa ndi gawo latsopano mu nthawi.
3.Fufuzani magetsi otsekera ndi kumbuyo kwamakono a chowotcha chamakono, malire a magetsi ochepetsera magetsi, malire apano a malire omwe alipo panopa, ndi mipata ndi mipata ya mpweya wa ogwirizanitsa osiyanasiyana.Ngati sichikukwaniritsa zofunikira, ziyenera kusinthidwa.
4.Fufuzani chowongolera chosinthidwa ndikuyang'anitsitsa chisonyezero cha cholozera cha ammeter poyambira injini ya dizilo.Ngati singano ya ammeter ikulozabe mbali ya "-" pamene injini ya dizilo ikugwira ntchito pa liwiro lapakati kapena pamwamba, izi zikutanthauza kuti kukhudzana kwa wosweka wamakono sikungatheke, ndipo chosinthira pansi chiyenera kuchotsedwa mwamsanga;Kupanda kutero, idzawononga batire, chowongolera, chowongolera jenereta, ndi zina zambiri. Ngati singano ya ammeter ikulozerabe "0" injini ya dizilo itangoyamba ku liwiro lovotera, kusintha kwa kufotokozera sikusinthidwa malinga ndi zofunikira zaukadaulo. , ndipo iyenera kufufuzidwanso ndi kusinthidwa.
