Kwenzekani uma uxuba amatheminali ebhethri emotweni

Iningi labanikazi bezimoto liyazethemba lokho ibhethri - idivayisi elula futhi akufanele kube nezinkinga ngokusetshenziswa kwayo. Iphutha elilinde abashayeli ukuthi kungenzeka badide amatheminali uma beshaja noma befaka ibhethri enjinini. Ezimotweni zesimanje, itheminali evumayo inkulu ngosayizi, ngakho-ke noma ifakwe ebumnyameni obuphelele, ingabonwa kalula ngokuthinta.

Nokho, ungangena esimeni esingemnandi lapho ufaka ibhethri emotweni yesitayela esidala, nalapho ushaja noma ukhanyisa ugwayi.

Imininingwane eyengeziwe lapha: indlela yokukhanyisa kahle imoto kwenye imoto.

Iziqeshana ze-Alligator zingosayizi ofanayo, ngakho-ke zingaxhunywa kalula ku-plus and minus. Imiphumela yokuguqulwa kwe-polarity iyahluka ngokuya ngezimo nemodeli yemoto.

Imiphumela yokuxhuma okungalungile kwamatheminali ebhethri enjinini

Isimo esidabukisa kakhulu ukwethulwa injini ngebhethri elixhumeke ngokungalungile. Isilinganiso "senhlekelele" sincike esivinini sokusabela somshayeli kanye nemodeli yemoto. Izinkinga ezilandelayo zingase ziphakame:

1. Ukuvala. Ezimweni ezingu-100%, ukuqala injini ngebhethri efakwe ngokungalungile kugcwele isifunda esifushane. Kuqhamuke izinhlansi emajoyintini, kuzwakale ukuchofozwa kuphuma ngisho nentuthu. Ukuthuthukiswa okuqhubekayo kwezenzakalo kuncike ekunakekeni kanye nesivinini sokusabela komshayeli. Uma ucisha umlilo ngokushesha bese umisa injini, ungadlula "ngegazi elincane": izintambo zizoncibilika, bese i-fuse izoshisa. Kulokhu, kwanele ukufaka esikhundleni se-fuse nezintambo.
2. Ukuthungela. Ukungayinaki inhlansi kuholela emlilweni ngaphansi kwe-hood. Izintambo ezincanyana ziyancibilika bese zivutha ngokushesha. Ngokunikwa ukusondela kwephethiloli no-oyela, ingozi yomlilo iphezulu ngokweqile.
3. Ukuphulwa kwe-ECU. Ukuhluleka kwama-electronics kuwumphumela onzima ngokulinganayo wephutha lokuxhumana. Ishiywe ngaphandle "kobuchopho" be-elekthronikhi, imoto izovele iyeke ukusebenza. Ukulungiswa kwe-ECU kusongela umnikazi wemoto ngezindleko ezinkulu zezinto ezibonakalayo.
4. Amandla ebhethri ancishisiwe. Uma amapuleti ebhethri exhunywe ngokungalungile, azofaka inqubo ye- "overdriving" bese eqala ukudilika. Umphumela wale nqubo engemihle ukwehla kwamandla ebhethri.
5. Ukuhluleka kwejeneretha. Esimeni esihle kakhulu, ibhuloho le-diode lizoqala ukushisa uma lifakwe ku-generator. Uma kungenjalo, i-polarity ehlehlisiwe izoholela ekutubekeni kwejeneretha. Isibani sebhethri kuphaneli sizokhanya. Lokhu kuzosho ukuthi i-generator idinga ukushintshwa.

Ukuxhumeka kwebhethri okungalungile lapho ishaja

Amathuba okuxhumana okungalungile kwamatheminali ngenkathi ishaja ibhethri angaphezulu kakhulu. Kunokuba ifakwe enjinini, njengoba kungekho umehluko obonakalayo phakathi kwamatheminali "amashaja". Ukuthuthukiswa kwezenzakalo kuleli cala kungase kuhluke. Ngekhwalithi ishaja i-fuse izoshaya futhi inqubo izokhipha isisodwa. Konke okusele ukushintsha i-fuse bese ushaja ibhethri uma ixhunywe kahle. Ukusebenzisa ishaja eshibhile yamaShayina kuzoholela ekuhlulekeni kwayo ngokuphelele.

Kwezinye izimo, i-fuse ayisizi futhi ukushaja kuyaqhubeka. Uma kutholakala iphutha ngesikhathi esifanele, kwanele ukushintsha i-polarity bese uqhubeka nenqubo yokushaja.

Ebhethrini eligcwaliswe ngokugcwele, inqubo yangaphakathi "yokuhlehlisa" iyenzeka. Ngokwemvelo, akunakwenzeka ukuxhuma iyunithi enjalo injini. Iphutha lingalungiswa ngokukhipha ibhethri ngokuphelele ngokuxhuma i-autolight noma ubukhulu. Lapho nje ibhethri selishajwe ngokuphelele, lishajwa nge-polarity efanele.

Uma uhlanganisa amatheminali ngenkathi "ukhanyisa" imoto

Iphutha lokuxhuma ngesikhathi sokukhanyisa yicala elinzima kakhulu, elingagcina lisenkingeni kuzo zombili izimoto. Yonke imoto izoba nomthelela okabili: kuzintambo nakusistimu ngesikhathi esisodwa. Uma ukukhanyisa kwenziwa ngenjini egijima, i-generator izophinde ihlupheke.

Ukwehluleka ukubheka i-polarity kungaholela ekwehlulekeni ngisho nokuqhuma kwebhethri lamandla aphansi. Uma ungasabeli phakathi kwemizuzwana emi-4-5, ibhethri ngeke libe namandla anele okuqalisa injini. Noma iyiphi into kagesi nayo ingathinteka: i-air conditioner, abaphakamisa amawindi, isiqophamazwi somsakazo, isiphequluli nokunye okunjalo.

Imiphumela yamaphutha lapho kuxhunyaniswa ama-terminals ayikhombisi okuhle kunoma ikuphi. Ngisho ne-hitch yesibili ingaholela ekuhlulekeni kwezinto eziningana zemoto, ngakho-ke kufanele uqaphele kakhulu lapho uxhuma ibhethri.

Imibuzo nezimpendulo:

Kufanele uxhume kanjani ama-terminals kubhethri? Kuya ngokuthi ibhethri lifakwe kanjani. Into esemqoka lapho uxhuma i-terminal eqondile akufanele uyivale nge-negative exhunyiwe (ungathinti umzimba wemoto).

Yini okufanele uyixhume ukuhlanganisa noma ukususa ebhethrini kuqala? Ukuze ungavali ngephutha i-electronics (ukuqinisa i-nati, ungathinta umzimba), lapho uxhuma ama-terminals, kungcono ukubeka kuqala i-positive bese ubeka i-terminal negative.

Ungayixhuma kanjani ishaja kwibhethri ngendlela efanele? Okokuqala, i-positive terminal ixhunyiwe, bese kuba i-negative terminal. Hlola ukuqina kokulungisa "izingwenya" (ukuze zingahlansi), bese uxhuma ishaja kusokhethi.

Ungayinqamula kanjani ibhethri emotweni? Amatheminali angaba muncu, ukuze ukhiye ungabambeki emzimbeni osekelwe phansi, kungcono ukuthi uqale ususe i-terminal engalungile, bese usonta into enhle. Bese ukhulula izibophelelo zebhethri.
