Nzira yekutarisa sei kubuda kwezvino pamotokari ine multimeter? Vhidhiyo
Mutyairi wese anoziva nezvemamiriro ebhatiri raburitswa. Nezuro chete yakabhadharwa nerubatsiro rwejaja otomatiki, uye kubva mangwanani chaiwo bhatiri rinoramba kutendeutsa. Panogona kuva nezvikonzero zvakawanda zvedambudziko iri:
- kusavapo-pfungwa - vakakanganwa kudzima mumwe wevatengi vemagetsi;
- kusabatana kwakashata kwevatengi - havadzimi mushure mekubvisa kiyi kubva pakupisa uye kudzima injini;
- yakawandisa michina yekuwedzera yakabatana, kusanganisira iyo alarm system, iyo isina kupihwa nehunhu hwemotokari uye kugona kwebhatiri;
- kuzviburitsa kwebhatiri nekuda kwekupfeka kwayo uye kudzikira munzvimbo inoshandisika yemahwendefa ekutungamirira.
Kana pasina chimwe chezviri pamusoro chakakodzera munyaya yako, saka pane chikonzero chimwe chete chasara - ikozvino kuvuza.
Sei kubuda kwezvino kuchiitika?
Chekutanga pane zvese, zvinofanirwa kutaurwa kuti kubhadharisa leakage kwakakamurwa mumapoka maviri:
- normal, natural;
- defective.
Bhatiri rinogara richipa mutero kunyange pakuzorora kune vatengi (anti-kuba, komputa). Zvakare, kurasikirwa kunoitika nekuda kwezvikonzero zvemuviri chete nekuda kwemusiyano ungangoita. Hapana chingaitwa pamusoro pekurasikirwa uku. Ndiko kuti, iwe unongofanirwa kuenderana nenyaya yekuti alarm inoshanda husiku hwese, zvishoma nezvishoma ichiburitsa bhatiri.
Kurasikirwa kwakakanganisika kunoitika nekuda kwematambudziko akasiyana kunze kweakanyorwa pamusoro apa:
- kugadziriswa kusina kunaka kwezviteshi pamagetsi ebheteri nekuda kwekusvibiswa uye oxidation;
- pfupi dunhu pakati pematenderedzwa emagetsi emagetsi emhando dzakasiyana-siyana dzakabatana - fan, jenareta, starter;
- chero midziyo yemagetsi haisi kurongeka;
- zvakare, kubatana kwakashata kwemidziyo yakananga kubhatiri, uye kwete kune mudziyo wemidziyo kuburikidza neiyo ignition switch.
Kubuda kwebhatiri kwechisikigo hazvikanganisi kugona kwayo uye mamiriro ehunyanzvi. Saizvozvo, mota ine sevhisi yemagetsi ekushandisa uye ine chaiyo yekubatanidza vatengi zvirongwa inogona kumira isina basa kwemazuva akati wandei. Muchiitiko ichi, kuzvisunungura kuchave kushoma. Kana kubuda kwacho kwakanyanyisa, saka maawa akati wandei anokwana kuti bhatiri ribude zvachose.
Dambudziko racho rinowedzerwawo nechokwadi, sezvatakambonyora munyaya ye vodi.su, kuti mumamiriro ezvinhu emaguta jenareta haina nguva yekugadzira magetsi akakwana kuti atengese bhatiri yekutanga kusvika ku100 muzana.
Kubuda kwebhatiri rakadzika ndicho chikonzero chinowanzoitika chekunyunyuta
Maererano nevatengesi mukutengesa motokari, chimwe chezvikonzero zvinowanzoitika zvekudzorera bhatiri pakunyunyuta ndiko kukurumidza kubuda kwebheteri uye kuvapo kwejira jena mu electrolyte, nekuda kwekuti inorasikirwa nekujeka uye inova nemakore. Sezvatakanyora kare, nyaya iyi haizovimbiswi, sezvo bhatiri harisi kushanda nekuda kwekukanganisa kwemuridzi. Chiratidzo ichi - gore electrolyte ine tsvina chena - inoratidza kuti bhatiri rave richidzokororwa pasi pemvura yakadzika. Saizvozvo, kuvuza kwazvino ndicho chimwe chezvikonzero zvekubuda kwebhatiri.
Sulfation, ndiko kuti, maitiro ekuumbwa kwemakristasi machena e-lead sulfate, mhedzisiro yakasikwa yekubuda. Asi kana bhatiri riri kushanda zvakajairika uye rinobudiswa mukati memiganhu inogamuchirwa, makristasi haakure kusvika kuhukuru hukuru uye ane nguva yekunyunguduka. Kana bhatiri richigara richibudiswa, ipapo makristasi aya anogara pamahwendefa, achiavhara, izvo zvinoderedza kukwanisa.
Saka, kuvapo kwekudonha kwemvura pamusoro pezvakajairika kunotungamira kune chokwadi chekuti iwe unofanirwa kugara uchichinja bhatiri. Uye chinhu chacho hachina kudhura. Naizvozvo, isu tinokurudzira kuti iwe nekukurumidza utarise kuparara uchishandisa nzira dzakareruka dzechinyakare. Kana kuti enda kuchiteshi chebasa, uko auto electrician ichakurumidza kuisa uye kugadzirisa kuvuza.
Leak test
Kushanda kuri nyore kuchakubvumira kuti uise chokwadi chekuvapo kwekurasikirwa kwemazuva ano muhuwandu, pasina kusungirirwa kune imwe midziyo yemagetsi.
Heano matanho ekutanga:
- tinodzima injini;
- isu tinotora tester toendesa kune iyo DC ammeter mode;
- tinokanda kure negative terminal yebhatiri yekutanga;
- tinoshandisa dema dema remuyedzo kune yakabviswa terminal, uye mutsvuku probe kune yakaipa bhatiri electrode;
- chiratidziro chinoratidza kubuda kwezvino.
Iwe unogona zvakare kuita mune imwe hurongwa: bvisa iyo yakanaka terminal kubva mubhatiri uye batanidza iyo isina kunaka ammeter probe kwairi, uye iyo yakanaka kune bhatiri terminal. Somugumisiro, dunhu rakazaruka rinoumbwa uye tinowana mukana wekuyera kubuda kwezvino.
Zvakanaka, kana zvinhu zvose zvichishanda zvakanaka uye pasina kukanganisa, kukosha kwekurasikirwa kwechisikigo, zvichienderana nehuwandu hwebheteri, haifaniri kudarika 0,15-0,75 milliamps. Kana iwe uine 75 yakaiswa, zvino iyi 0,75 mA, kana 60 iri 0,3-0,5 milliamps. Ndiko kuti, muhuwandu kubva ku0,1 kusvika ku1 muzana yebhatiri simba. Panyaya yemitengo yakakwirira, zvakakosha kutarisa chikonzero.
Kuwana chikonzero harisi basa rakaoma zvikuru. Iwe unofanirwa kuita mune inotevera kutevedzana, uchisiya iyo ammeter probes yakabatana kune bhatiri terminal uye yakabviswa terminal:
- bvisa chifukidziro chefuse block;
- tora fuse imwe neimwe kubva pachigadziko chayo;
- isu tinotarisa kuverengwa kwemuongorori - kana asingashanduki mushure mokubvisa imwe kana imwe fuse, saka iyi mutsara haisi iyo inokonzera kubuda kwezvino;
- apo, mushure mekubvisa fuse, zviratidzo zviri pa multimeter kuratidzira zvinodonha zvakanyanya kune zvakakosha zvezita rekudonha ikozvino kwemotokari iyi (0,03-0,7 mA), ichi ndicho chigadzirwa chakabatana neiyi fuse chinokonzera. kurasikirwa kwezvino.
Kazhinji, pazasi pechifukidziro chepurasitiki chebhokisi refuse, panoratidzwa kuti ndechipi chikamu chemagetsi emota iyi kana iyo fuse ine basa rekuti: rear hwindo kupisa, mamiriro ekunze system, redhiyo, alarm, cigarette lighter, contact relay, zvichingoenda zvakadaro. Chero zvazvingava, zvakakosha kutarisa dhiyabhorosi yemagetsi emagetsi emuenzaniso uyu wemotokari, sezvo zvinhu zvakawanda zvinogona kubatanidzwa kune imwe mutsara kamwechete.
Kana mutengi ari kukonzera kuvuza akabatana kuburikidza nerelay, iyo relay inofanirwa kuongororwa. Zvinokwanisika chikonzero - yakavharwa mazita. Kudzima kwechinguva mudziyo unokonzeresa kudonha uye shandura relay kune imwe nyowani yemhando imwe chete. Zvichida nenzira iyi iri nyore unogona kugadzirisa dambudziko racho.
Zvakanyanya kuoma inyaya apo kuvuza kunoitika kuburikidza nejenareta kana kutanga. Uyezve, hazvizogoneki kuziva chikonzero nekubvisa mafizi kana ikozvino ichiyerera kuburikidza neyakakuvadzwa wire insulation. Iwe unozofanirwa kuongorora zvizere wiring dzese, kana kuenda kune ane ruzivo rwemagetsi ane midziyo inodiwa.
