Momwe mungayang'anire kutsogolo kwa galimoto ndi multimeter: malangizo ndi sitepe

Beteli pamotokomo kapena njinga yamoto silikuimbidwa mlandu kapena kubwezeretsedwa, choyamba, nkofunika kuonetsetsa kuti jenereta yotumizira. Inde, vutoli lingayambitsidwe ndi zifukwa zina zambiri, koma nthawi zambiri zimachokera. Koma momwe mungayang'anire cholojekera ndi multimeter? Za izi ndikuyankhula.

Cholinga ichi chikukonzekera kuteteza batri ndikuwonjezera moyo wake kwa zaka zambiri. Ndipo zonsezi ngakhale zikugwirizana. Kotero, ngati mwadzidzidzi mutulukira kuti galimotoyo imayamba molakwika usiku, tawonani kuti kulira koyera ndi ntchito yoipa yoyambira, ndiye nthawi yoti mukwere pansi. Choncho ndikofunikira kudziwa momwe mungayang'anire choyambira choyamba ndi multimeter, chifukwa ngati chirichonse chatsala monga momwe zilili, ndiye batiri "afa" mofulumira.

Tanthauzo

Musanayambe kujambulira ndi multimeter, muyenera kumvetsetsa zonse - zowonjezera. Chojambulirachi chakonzedwa kuti chiziyendetsa jenereta ya galimotoyo, yomwe imalepheretsa kubwezeretsa bateri. Choncho, chifukwa cha izi, mabatire amatha nthawi yaitali.

Kawirikawiri, kachilombo kameneka kameneka kamakhala koyendetsa magetsi komwe sikulola mpweya wopitirira 14.5 volts. Chipangizo ichi chiri cholondola kwambiri, ndipo ndi chovomerezeka kwa mitundu yonse ya makina. Komabe, pali mitundu yambiri ya kubwereranso.

Mitundu

Ngati mumakhala ndi mitundu yambiri yokha, ndiye kuti pali mitundu iwiri yokha, ndipo imagwira ntchito mofanana - kuonjezera kapena kuchepetsa mphamvuyo kufunika kwake - 14.5 volts. Njira yoyamba ndi yakuti chophatikizidwa chikugwirizana ndi msonkhano wa brush. Nthawi zambiri zimapangidwira jenereta yokha, ndipo mzere womwe umapezeka umakhala m'nyumba zomwe maburashi akuyikidwa.

Komanso, chophatikizidwacho chingapangidwe monga chipangizo chosiyana, chomwe chikuphatikizidwa ku thupi la makina, ndipo mawaya achokera kwa jenereta, ndiyeno ku batiri.

Milandu ya mitundu yonse iwiri yotumizidwa imadzazidwa ndi guluu kapena tizilomboti, ndipo sikunakonzedwe nkomwe. Choncho, ngati tiyang'ana retractor relay ndi multimeter ndipo izi sizikutanthauza, tidzasowa kugula latsopano. Mwamwayi, ndi zotchipa, makamaka zinyumba za VAZ zoweta. Choncho, ndizosavuta komanso zosavuta kugula zatsopano, osati kale.

Ngati "ifa", ndiye kuti batiri idzabwezeredwa. Izi zikutanthawuza kuti kutumizidwa ndi nthawi yosintha. Koma izi ndizofunika kudziwa momwe mungayang'anire cholojekiticho ndi multimeter, chifukwa tikuyenera kudziwa kuti chiri mmenemo, osati mbali ina iliyonse ya jenereta. Zomwe zilipo ndizomwe mungachite kuti muwone: popanda kuchotsa ku galimoto ndikuzichotsa.

Kodi mungayang'ane bwanji jenereta yomwe ili ndi multimeter, popanda kuchotsa makina?

Zizindikiro za kulephera kwa woyang'anira zikuwoneka bwino. Makamaka ngati zenera liri pansi pa zero. Beteli nthawizonse ikhoza kukhala yotsitsimutsidwa kapena kubwezeretsedwa. Pachiyambi choyamba, ndalama zochepa za bateri zimatha kudziwika mosavuta momwe njira yoyambira imayendetsera galimotoyo. Adzangopotoza, ndipo palibe. Nthawi zina pamene mutembenuza makiyi, palibe chomwe chikuchitika konse, ndipo mababuwo pazanja amachoka.

Kubwezeretsa kwa batiri kumakhala chimodzimodzi. Zidzakhala chimodzimodzi, kuphatikizapo electrolyte kuchokera kumatini a batri adzaphika. Dziwani kuti recharge ikhoza kuchepetsedwa m'mabanki a electrolyte. Chifukwa cha kutuluka kwa mpweya, chovala choyera chingapangidwe pamwamba pa betri. Mbali za thupi pansi pa batiri zingakhalenso ndi malaya oyera. Kawirikawiri, ndi zizindikiro zoterezi, madalaivala amaganiza kuti bateri yawonongeka, koma zedi ziri bwino, koma nkhaniyi muwongolera olamulira, ndipo ili pa iye amene ayenera kumvetsera. Koma pazimenezi muyenera kudziwa momwe mungayang'anire zojambulazo ndi multimeter.

Sikovuta kuchita izi. Kuti tichite izi, tenga multimeter yathu ndikuyiyika ku modelo ya voltmeter. Ndi chithandizo chake, tikhoza kuyesa magetsi pamapeto a batri ndi kuyendetsa galimoto. Onani kuti injini ikatha, magetsi amafunika kukhala pakati pa 12.4-12.7 V. Ngati mwachitsanzo, magetsi ali 12 V, ndiye kuti batiri ayenera kulipiritsa ndikufufuza zomwe zimayambitsa undercharging.

Mavuto ochilendo

Choncho, yambani injini, yikani voltmeter modelo pa mulingo wa 20 V mulumikizidwe ndikulumikiza mayesero ake amatsogolera kumapeto. Ngati mpweya uli pafupi ndi 13.2-14 V, zikutanthawuza kuti chirichonse chili ndi batri. Kuonjezera injini mofulumira mpaka 2000-2500. Mpweya woterewu uyenera kukula mpaka pafupifupi 13.6-14.3 V, yomwe ili ndi malire. Tsopano yonjezerani liwiro kufika pa 3500, ndipo mpweya uyenera kuwonjezeka kufika 14-14.5 V. Pakati pa zizindikiro zoterezi ziyenera kukhala magetsi mu batri yoyendetsa ntchitoyo.

Zomwe sizinali zachilendo pa multimeter

Ngati zoyenerazo zikusiyana ndi zomwe zikuwonetsedwa ku mbali yayikulu kapena yocheperapo, izi zikuwonetsa cholakwika muzololedwa. Mwachitsanzo, ngati magetsi akutsikira ku 12 V ndi kuwonjezeka kwa injini mofulumira, ndiye kuti mwachidziwikire chinachake ndi cholakwika. Komanso, kuwonjezera mpweya kufika pa 15-16 V kukuwonetsa kusagwira ntchito kwa wolamulira wolowerera.

Sikuti nthawi zonse magetsi amatha kusokoneza, koma nthawi zambiri. Nthawi zina jenereta yokha imatha kulephera. Mulimonsemo, pamene kuthamanga kwa magetsi kumachitika, choyamba chofunika kusintha kusintha, ndipo ngati vutoli likupitirira, ndiye ndikofunikira kuti mutenge jenereta ndikuyesa dongosolo.

Onetsetsani kuti wothandizira otsogolera wothandizira

Ngati msonkhano wa burashi umagwirizanitsidwa ndi jekeseni, jenereta iyenera kuchotsedwa kuti iwonedwe. Choyamba, ndikofunikira kuyang'anitsitsa dera loyendetsa, lomwe likugwiritsidwa ntchito lerolino pamagalimoto ambiri akunja komanso ngakhale magalimoto oyendetsa.

Kuti tichite zimenezi, tifunika kuchotsa ndi kusokoneza jenereta, popeza mfundo yomwe tikufunikira ikuphatikizidwa pazitsulo za jenereta, kumene maburashi amayenda. Tikuyang'ana pawindo pa jenereta, tisiyanitsa chophimba, timachotsa msonkhano wa brush ndi kuyeretsa. Kawirikawiri izo ziri mu fumbi la graphite.

Tsopano tikufunikira kusonkhanitsa dera lapadera pogwiritsa ntchito magetsi omwe ali ndi katundu wambiri. Timafunikiranso betri, chifukwa mphamvu kapena galimoto sizimagwira ntchito popanda izo. Choncho, gwirizanitsani chojambulira ku batiri komanso mofanana ndi wotsogolera zinthu, ndipo kwa omaliza timagwirizananso ndi babu yowunikira 12-volt.

Pogwiritsa ntchito izi, kuwala kudzapitirira - izi ndi zachilendo, chifukwa nkhono ya brush ndi woyendetsa, ndipo pamtendere mpweya uli 12.7 V. Tsopano tikufunika kukweza mpweya pa chojambulira kuti 14.5 V. Nyali iyenera kutuluka pamene chizindikiro ichi chifikira. Pambuyo pake, 14.5 V ndi "kudula" kwa kuwonjezeka kwamtundu. Ndipo ngati nyali ikupita, zikutanthawuza kuti kubwezeretsa kwagwira ntchito, ndipo kwenikweni ndi yothandiza.

Apo ayi, ngati magetsi amatha kufika 15-16 V, ndipo kuwala kukugwera, zikutanthawuza kuti chololedwa sichipereka mpata. Pankhani iyi, iyenera kuti ikhale yatsopano.

Tsopano mukudziwa momwe mungayang'anire wotsogolera wogwiritsa ntchito multimeter, ndipo mukhoza kuchita nokha.
