Ukuhlelwa okusisiseko
1. I-Alternator voltage regulator inokwahlulwa ibe: ngokomgaqo osebenzayo:
(1) Qhagamshelana nomlawuli wamandla ombane
Isilawuli sombane woqhagamshelwano sisetyenziswa kwangethuba, le frequency yonxibelelwano yomlawuli iyacotha, kukho inertia yomatshini kunye ne-inertia ye-electromagnetic, ukuchaneka komgaqo wombane ophantsi, unxibelelwano olulula ukuvelisa iintlantsi, uphazamiseko olukhulu lukanomathotholo, ukuthembeka okubi, ubomi obufutshane, bususiwe.
(2) Umlawuli weTransistor
Ngophuhliso lwetekhnoloji ye-semiconductor, abalawuli be-transistor bamkelwe.Izibonelelo zayo zezi: i-frequency transistor switching iphezulu, kwaye ayivelisi iintlantsi, ukuchaneka okuphezulu kohlengahlengiso, kodwa ikwanenzuzo yobunzima bokukhanya, ubungakanani obuncinci, ubomi obude, ukuthembeka okuphezulu, ukuphazamiseka kwerediyo encinci, njl., kwaye ngoku ibanzi ngokubanzi. esetyenziswa eDongfeng, eJiefang kunye neentlobo ngeentlobo zeemodeli ezisezantsi.
3) Umlawuli wesekethe odibeneyo
Ukongeza kwiinzuzo zabalawuli be-transistor, abalawuli beesekethe ezidibeneyo nazo zincinci-zincinci, zifakwe ngaphakathi kwijeneretha (ekwaziwa ngokuba ngabalawuli abakhelwe ngaphakathi), ukunciphisa iingcingo zangaphandle, kunye nesiphumo sokupholisa siphuculwe, kwaye ngoku sisetyenziswa ngokubanzi Santana.I-Audi kunye nezinye iimodeli ze-sedan.
(4) Umlawuli olawulwa yikhompyutha
Emva kokulinganisa umthwalo opheleleyo wenkqubo ngumtshina womthwalo wombane, isiginali ithunyelwa kwikhompyuter yejenereyitha, emva koko isilawuli sombane wejenereyitha silawulwe yikhompyuter yenjini, kwaye isekethe yemagnethi ivulwa kwaye icinywe ngexesha elifanelekileyo. , oko kukuthi, ukusebenza okuqhelekileyo kwenkqubo yombane kunokuqinisekiswa ngokuthembekileyo, ibhetri inokuhlawulwa ngokwaneleyo, kwaye umthwalo we-injini ungancitshiswa kwaye uqoqosho lwamafutha lunokuphuculwa.Ngokomzekelo, i-Shanghai Buick, i-Guangzhou Honda kunye nezinye iijeneretha zemoto zisebenzisa lo mlawuli.
2. Umlawuli wombane
Ngokohlobo lwentsimbi oluhambelanayo lunokwahlulwa lube:
(1) Isilawuli sodidi lwangaphakathi lwentsimbi
I-voltage regulator ilungele ukuhambelana ne-alternator yangaphakathi yohlobo lwe-tie ibizwa ngokuba yi-internal tie-type regulator;
(2) Isilawuli sodidi lwentsimbi yangaphandle
I-voltage regulator ilungele ukuhambelana ne-alternator yohlobo lwangaphandle ibizwa ngokuba yi-outer tie-iron regulator.
Kwinkqubo yokusetyenziswa, kumlawuli we-transistor, kukulungele ukusebenzisa umlawuli ochazwe kwincwadana yemoto, ukuba ezinye iimodeli zisetyenziselwa ukutshintshwa, ngaphezu kwe-voltage yegama kunye nezinye iiparitha ezichaziweyo kunye nomlawuli wokuqala uyafana. i-substitute regulator kufuneka ifane nefom yentsimbi ye-original regulator, kungenjalo, i-generator ayinakusebenza kakuhle ngenxa yesekethe yokuvuselela.Kubalawuli beesekethe ezidibeneyo, kufuneka bazinikele kwaye abanako ukutshintshwa.
Sebenzisa ulondolozo
Sebenzisa ulondolozo
Umlawuli ngokuqhelekileyo akavumelekanga ukuba aqhawule isigqubuthelo ngexesha lokusetyenziswa, kwaye imeko eqhelekileyo kukuqhuba uhlolo olubanzi kunye nokugcinwa rhoqo emva kwe-200h okanye njalo, kwaye umxholo wayo ulandelayo:
1.Susa i-case kwaye uhlolisise indawo yokudibanisa ukungcola kunye nokutshisa umonakalo.Ukuba kukho ukungcola, sula indawo yokudibanisa ngephepha elicocekileyo.Ukuba unxibelelwano luvaliwe okanye alulingani kwaye uqhagamshelwano lungalunganga, lugudiswa ngokubanzi ngephepha lesanti elithi "00" okanye umcu wesanti, kwaye kosulwe ngephepha elicocekileyo.
2.Hlola ukuqina kwekhonkco nganye, ukulinganisa ukuchasana kunye nexabiso lokumelana nekhoyili nganye.Ukuba kukho umonakalo, kufuneka kulungiswe okanye kufakwe indawo entsha ngexesha.
3.Khangela i-voltage yokuvala kunye ne-back current ye-breaker yangoku, umlinganiselo we-voltage yokunciphisa i-voltage reducer, umda okhoyo womda wangoku we-stopper yangoku, kunye nezikhewu kunye nezikhewu zomoya zoqhagamshelwano ezahlukeneyo.Ukuba ayihambelani neemfuno, kufuneka ilungiswe.
4.Khangela i-regulator ehlengahlengisiweyo kwaye ubeke ingqalelo kwisalathisi sokutshaja kwe-ammeter pointer xa uqala injini ye-diesel.Ukuba inaliti ye-ammeter isakhomba kwicala elithi "-" xa injini ye-diesel isebenza ngesantya esiphakathi okanye ngaphezulu, oku kuthetha ukuba umnxeba we-breaker yangoku awunqanyulwanga, kwaye ukutshintshwa komhlaba kufuneka kukhutshwe ngokukhawuleza;Ngaphandle koko, iya kulimaza ibhetri, umlawuli, ijenereyitha yokutshaja, njl. Ukuba inaliti ye-ammeter isakhomba "0" emva kokuba injini ye-diesel iqala kwisantya esilinganiselweyo, ukulungiswa kwenkcazo ayilungiswanga ngokweemfuno zobugcisa. , kwaye kufuneka ihlolwe kwakhona kwaye ilungiswe.
