Ukuhlukaniswa okuyisisekelo
1. Isilawuli se-Alternator voltage singahlukaniswa sibe: ngokuvumelana nesimiso sokusebenza:
(1) Xhumana nesilawuli sikagesi
Isilawuli se-voltage yokuxhumana sisetshenziswa ngaphambili, lesi silawuli sokudlidliza imvamisa sihamba kancane, kukhona inertia yemishini kanye ne-electromagnetic inertia, ukunemba kokulawulwa kwamandla kagesi aphansi, ukuthintana okulula ukukhiqiza izinhlansi, ukuphazamiseka okukhulu komsakazo, ukwethembeka okubi, impilo emfushane, kuqediwe.
(2) Isilawuli se-Transistor
Ngokuthuthukiswa kobuchwepheshe be-semiconductor, abalawuli be-transistor bamukelwe.Izinzuzo zayo yilezi: imvamisa yokushintsha i-transistor iphezulu, futhi ayikhiqizi izinhlansi, ukunemba okuphezulu kokulungiswa, kodwa futhi inezinzuzo zesisindo sokukhanya, usayizi omncane, impilo ende, ukwethembeka okuphezulu, ukuphazamiseka okuncane komsakazo, njll., futhi manje sekubanzi kakhulu esetshenziswa e-Dongfeng, eJiefang kanye nezinhlobonhlobo zamamodeli asezingeni eliphansi.
3) Isilawuli sesifunda esihlanganisiwe
Ngaphezu kwezinzuzo zama-transistor regulators, izilawuli zesekethe ezididiyelwe nazo ziyi-ultra-small, zifakwe ngaphakathi kwejeneretha (ezaziwa nangokuthi izilawuli ezakhelwe ngaphakathi), zinciphisa izintambo zangaphandle, nomphumela wokupholisa usuthuthukisiwe, futhi manje ususetshenziswa kabanzi Santana.I-Audi namanye amamodeli e-sedan.
(4) Isilawuli esilawulwa yikhompyutha
Ngemva kokulinganisa isamba somthwalo wesistimu ngomtshina wokulayisha ugesi, isignali ithunyelwa kukhompyutha ye-generator, bese isilawuli se-voltage ye-generator silawulwa yikhompyutha yenjini, futhi isifunda samagnetic field sivulwa futhi sivalwe ngesikhathi esifanele. , okungukuthi, ukusebenza okuvamile kwesistimu kagesi kungaqinisekiswa ngokuthembekile, ibhethri ingashajwa ngokwanele, futhi umthwalo wenjini ungancishiswa futhi umnotho wamafutha ungathuthukiswa.Isibonelo, i-Shanghai Buick, i-Guangzhou Honda namanye ama-generator emoto asebenzisa lesi silawuli.
2. Isilawuli samandla kagesi
Ngokusho kohlobo lwensimbi oluhambisanayo lungahlukaniswa lube:
(1) Isilawuli sohlobo lwensimbi yangaphakathi
Isilawuli sikagesi esilungele ukumataniswa ne-alternator yangaphakathi yohlobo lwe-tie sibizwa ngokuthi isilawuli sohlobo lwe-tie yangaphakathi;
(2) Isilawuli sohlobo lwensimbi yangaphandle
Isilawuli sikagesi esilungele ukumataniswa ne-alternator yangaphandle yohlobo lwe-tie sibizwa ngokuthi isilawuli se-tie-iron yangaphandle.
Enqubweni yokusetshenziswa, kumlawuli we-transistor, kungcono ukusebenzisa isilawuli esichazwe encwadini yemoto, uma amanye amamodeli asetshenziselwa ukushintshwa, ngaphezu kwe-voltage yegama kanye neminye imingcele ecacisiwe kanye nomlawuli wangempela ofanayo, i-substitute regulator kufanele ifane nefomu lensimbi yomlawuli wokuqala, ngaphandle kwalokho, i-generator ingase ingasebenzi kahle ngenxa ye-excitation circuit.Kubalawuli besifunda abahlanganisiwe, kufanele bazinikezele futhi abakwazi ukushintshwa.
Sebenzisa ukulungisa
Sebenzisa ukulungisa
Isilawuli ngokuvamile asivunyelwe ukuqaqa ikhava ngesikhathi sisetshenziswa, futhi isimo esivamile siwukuhlola nokunakekela okuphelele njalo ngemva kwamahora angu-200 noma ngaphezulu, futhi okuqukethwe kwawo kungokulandelayo:
1.Susa ikesi bese uhlola indawo othintana nayo ukuze uthole ukungcola nokusha umonakalo.Uma kukhona ukungcola, sula indawo yokuxhumana ngephepha elihlanzekile.Uma othintana naye enqanyuliwe noma engalingani futhi othintana naye ebuthaka, ngokuvamile ulungiswa nge-"00" sandpaper noma i-sand strip, futhi ekugcineni isulwe ngephepha elihlanzekile.
2.Hlola ukuqina kwesixhumi ngasinye, kala ukumelana nenani lokumelana ngekhoyili ngayinye.Uma kunomonakalo, kufanele kulungiswe noma kufakwe ingxenye entsha ngesikhathi.
3.Hlola i-voltage yokuvala kanye ne-back current ye-breaker yamanje, i-voltage ekhawulelwe yesinciphisi se-voltage, umkhawulo wamanje womkhawulo wamanje wesivalo samanje, kanye nezikhala nezikhala zomoya zoxhumana nabo abahlukahlukene.Uma ingahlangabezani nezidingo, kufanele ilungiswe.
4.Hlola isilawuli esilungisiwe futhi unake inkomba yesikhombisi se-ammeter sokushaja lapho uqala injini yedizili.Uma inaliti ye-ammeter isakhomba ohlangothini "-" lapho injini ye-diesel isebenza ngesivinini esiphakathi noma ngaphezulu, lokhu kusho ukuthi ukuthintana kwe-breaker yamanje akunqanyuliwe, futhi inkinobho yomhlabathi kufanele inqanyulwe ngokushesha;Uma kungenjalo, izolimaza ibhethri, isilawuli, ijeneretha yokushaja, njll. Uma inaliti ye-ammeter isakhomba ku-"0" ngemuva kokuthi injini ye-diesel iqale ngesivinini esilinganiselwe, ukulungiswa kwencazelo akulungiswa ngokuvumelana nezidingo zobuchwepheshe. , futhi kufanele ihlolwe kabusha futhi ilungiswe.
