Okokufundisa: ungashaja kanjani ibhethri lesithuthuthu

Amakhaza ayakhala emnyango ... futhi akhiphe amabhethri ezithuthuthu zethu nezithuthuthu. Isikhumbuzo esincane sobuchwepheshe sokulondoloza usuku ... ngokuzayo.

Izimo ezahlukahlukene zinethonya elinamandla ukuqala isithuthuthu ebusika kanye / noma ngemuva kwesikhathi eside sokungasebenzi... Okokuqala, kunjalo, Umthamo webhethri... Kufanele wazi ukuthi ancipha ngokulingana nokushisa kwangaphandle. Ngokuvamile kucatshangwa ukuthi emazingeni okushisa amancane angaphansi kuka-20 °, amandla ebhethri azokwehla ngo-1% ngawo wonke ama-2 °. Ngamanye amagama, ku-0 ° lokhu kulahleka kuzoba yi-10%, ku -10 ° 15%, njll. Kulokhu, kuyangezwa ukulahleka kwenkokhiso yebhethri uma kwenzeka kungasebenzi ukulahlekelwa okungaphezulu noma okungaphansi kwesikhathi eside, okuncike ohlotsheni lwebhethri, ukuhola kwendabuko, ukungalondolozwa, okomile, i-gel, i-lithium, njll. Ibhethri elijwayelekile lilahlekelwa yi-50% yenkokhelo yalo ngemuva kwezinyanga eziyi-3-5.

Ukusebenza kwebhetri nokushaja

Kulokhu kungeziwe izingqinamba ezibucayi zemishinikufaka phakathi i-viscosity kawoyela, ekhuphuka ngokushisa okunciphile ngakho-ke kudinga amandla amaningi ukusebenzisa injini lapho kubanda. Kumele futhi sibheke ne ukusetshenziswa kwemishini ehlukahlukene yesithuthuthu... Ikakhulu, eminyakeni yamuva nje, ukukhanyisa isibani sekuyimpoqo, ngakho-ke asisakwazi ukukucisha (ngenxa yokushoda kweswishi emotweni) ukonga amandla amaningi ngangokunokwenzeka ku-starter. Okufanayo kuya ngokushayela iphampu kaphethiloli noma ukufudumeza ama-carburetors ngama-resistors, aphinda asebenzise amanye amandla adingekayo.

Ngakho-ke, kulula ukukuqonda lokho ukwehluleka okuncane kwebhethri kanye / noma isekhethi yokushaja kuvame ukuphoqa ukuba uphinde uhambe ngezinyawo... Kungakho udinga ukunakekela ibhethri lakho (futhi nesithuthuthu sakho). Uma usebenzisa isithuthuthu sakho nsuku zonke nakunoma isiphi isimo sezulu (wenze kahle!), Cishe awusoze wahlangabezana nokwehluleka kwebhethri okuvimbela ngempela, ngasese. inikwa amandla njalo ngenxa yesekethe layo likagesi... Ngakolunye uhlangothi, uma usebenzisa isithuthuthu sakho ku i-episodic kanye / noma isizini, nokuthi izinsuku ezinhle ezizayo zivuse umphefumulo wakho webhayisikili, okuzayo ngokulandelayo kuzokuthakazelisa kakhulu.

Ukunakekelwa kwebhethri yezithuthuthu: Ukubonisana neSanatorium

Abantu abaqaphile abafunde i-athikili ethi "Kusebusika, yiba nobusika obuhle esithuthuthu sakho", vele nqamula ibhethri bese uyigcina endaweni eyomile nefudumele.... Ngaphandle kwalokho, kuphephile ukusho ukuthi ibhethri lakho lihle kakhulu. kukhishwe ngokuphelele kepha kuyatholakala, esimweni esibi kakhulu ... ukuthi idinga ukuphinda isetshenziswe kabusha ngokushesha. Ngakho-ke, okokuqala, kuyadingeka lawula umthwalo wayo.

Ukuhlola ibhethri ejwayelekile yesithuthuthu: abahlonyelwe kakhulu kuwe kwesinye isikhathi banakho isikali se-asidi, noma idivayisi elawula iseli ngalinye lebhethri. Ngakho-ke, ukwenza lokhu, kuyadingeka ukuthi ususe ipulagi ngalinye, ucwilise isikali se-asidi ku ... acid, ushaye uketshezi bese ulandela imininingwane enikeziwe.

Uma kukhona okonakele (isikali esibomvu sesikali se-asidi), khona-ke ibhethri alinaso (isifunda esifushane seseli). Faka izinto njengoba kudingeka amanzi angenawo amanzi... Uma ibhethri liqhubeka nokusebenza, shaja. Kulokhu, qaphela amashaja ezimoto, angaba namandla kakhulu. Uncamela imodeli yesithuthuthu esishaja kancane, ezokwazi ukudlula ibhethri yamanje ephindwe izikhathi eziyi-10 kunomthamo webhethri (isibonelo: ibhethri elingu-1,12 Ah lizokhokhiswa njengamanje ongu-11,2 A).

Esimweni - kungenzeka kakhulu - awunaso isikali, i-multimeter izokwenza umsebenzi wayo, bona ngezansi.

Ukuhlola ibhethri lesithuthuthu nge-multimeter

Ukuhlola ibhethri lesithuthuthu elingena sondlo:

hlola i-voltage nge-multimeter (khetha isikhundla se-DC). Uma i-voltage elinganisiwe isendaweni engu-12,6 kuye ku-13 V, ibhethri ishajeke ngokugcwele futhi ilungele ukusetshenziswa. Phakathi kuka-12 no-12,5 V.ukushaja kabusha kuyadingeka (izinyathelo ezifanayo nokungenhla, ngesikhathi samanje esiphindwe ka-10 kunomthamo webhethri wokushaja). Ekugcineni, amandla alinganisiwe angaphansi kuka-10,3 V ikhombisa ibhethri elikhishiwe elingakwazi ukugcwaliswa kabusha (ungalilahli, ulisebenzise kabusha). Isixwayiso, ibhethri elinamandla angaphezu kuka-13 V ezikhumulweni zayo kugcwala ngokweqile, kuvame ukufinyelelwa, ukuthula emphefumulweni wakhe.

Yini ishaja yebhethri yesithuthuthu? Funda umhlahlandlela wethu osebenzayo lapha

Ngikhuluma nje

Iseluleko sethu sokuqala isithuthuthu sakho ngemuva kwesikhathi eside sokungasebenzi (ikakhulukazi ubusika):

- gcina isithuthuthu sakhe ngemizuzwana : umswakama akuyona umngane omkhulu, ikakhulukazi uma ubanda

- ukuqaqa ibhethri futhi ugcine endaweni eyomile ekamelweni lokushisa.

- Njalo shaja ibhethri ngaphambi kokulondoloza isikhathi eside. Ngaphandle kwalokho, isheshe isulpheded futhi izobhujiswa ngokungenakuguqulwa ...

- hlola umthwalo njalo khipha ibhethri (okungenani kanye ezinyangeni ezimbili).

- hlola ukushajwa kwebhethri ngaphambi kokuhlanganisa kabusha ngesithuthuthu bese ushaja kabusha uma kunesidingo.

– qala kabusha isithuthuthu ngemva kwesikhathi eside sokungasebenzi ngaphandle kokuhlehlisa, ukuhlola kanye / noma ukushaja ibhethri. ukulahlwa ngokuvamile... Kulokhu, ungagcizeleli: uma ibhethri lingaphansi kancane, maningi amathuba onawo “Ukubuyisela” ngeshaja efanelekile (uma kungenasibabule).

- ungalokothi ugijime isithuthuthu esinama-clamp (okungukuthi, ngokuyixhuma kwenye ibhethri), ngemuva kokuyikhipha ngokuphelele. Ngoba kulokhu, ngemuva kokuqala kabusha ibhayisikili i-generator yayo izokunikeza okwamanje kakhulu okuzophinde kudale umonakalo omkhulu kubhethri (ngamabhethri akhishwe kakhulu, kufanele kukhethwe ukushaja kwesikhathi eside).
