Kala soocida aasaasiga ah
1. Xakamaynta tamarta beddelka waxa loo qaybin karaa: sida uu qabo mabda'a shaqada:
(1) Xiriiriyaha korantada
Xakamaynta korantada xiriirinta ayaa horay loo dabaqay, kormeerahaan xiriiriyaha inta jeer ee gariirku waa mid gaabis ah, waxaa jira inertia farsamo iyo korantada korantada, saxnaanta xakamaynta korantada hooseeya, xiriir fudud si loo soo saaro dhimbiil, faragelin weyn oo raadiyaha, kalsoonida liidata, nolosha gaaban, waa la tirtiray.
(2) Xakameeyaha transistor
Iyadoo horumarinta tignoolajiyada semiconductor, transistor regulators ayaa la qaatay.Faa'iidooyinkeedu waa: inta jeer ee beddelka transistor-ka waa mid sarreeya, mana soo saaro dhimbiilo, saxnaanta hagaajinta sare, laakiin sidoo kale waxay leedahay faa'iidooyinka miisaanka fudud, cabbirka yar, cimri dheer, kalsoonida sare, faragelinta yar ee raadiyaha, iwm, oo hadda aad u ballaaran. loo isticmaalo Dongfeng, Jiefang iyo noocyo kala duwan oo heer hoose ah.
3) Nidaamiye wareeg ah oo isku dhafan
Marka lagu daro faa'iidooyinka maamulayaasha transistor-ka, nidaamyada isku-dhafan ee isku-dhafan ayaa sidoo kale ah kuwo aad u yaryar, oo lagu rakibay gudaha koronto-dhaliyaha (sidoo kale loo yaqaan nidaamka-ku-dhiska), yaraynta fiilooyinka dibadda, iyo saameynta qaboojinta ayaa la hagaajiyay, waxaana hadda si ballaaran loo isticmaalaa in Santana.Audi iyo moodooyinka kale ee sedan.
(4) Nidaamiyaha kombuyuutarku maamusho
Ka dib marka la cabbiro culayska guud ee nidaamka aaladaha rarka korantada, signalka waxaa loo dirayaa kombuyuutarka dhalisa, ka dibna matooriyaha korantada waxaa xakameynaya kombuyuutarka matoorka, wareegga magnetic field-ka ayaa shid iyo dami waqti ku habboon. , taas oo ah, hawlgalka caadiga ah ee nidaamka korantada ayaa si kalsooni leh loo dammaanad qaadi karaa, batteriga si ku filan ayaa loo dallaci karaa, culeyska matoorkana waa la dhimi karaa, dhaqaalaha shidaalkana waa la hagaajin karaa.Tusaale ahaan, Shanghai Buick, Guangzhou Honda iyo matoorrada kale ee baabuurta ayaa isticmaala nidaamiyahan.
2. Xakamaynta korantada
Marka loo eego nooca birta beddelka ah ee is-waafaqaya waxa loo qaybin karaa:
(1) Nidaamiyaha nooca birta gudaha
Xakamaynta korantada ee ku habboon is waafajinta beddelka nooca-xidheenka gudaha waxa loo yaqaan xeer-beegtida gudaha;
(2) Xakamaynta nooca birta ee dibadda
Xakamaynta korantada ee ku haboon in lala jaanqaado beddelka nooca-xidheenka dibadda ah waxaa loo yaqaannaa hagaha tie-birta dibadda.
Inta lagu jiro habka isticmaalka, loogu talagalay xakameynta transistor-ka, waxaa ugu wanaagsan in la isticmaalo nidaamiyaha lagu qeexay buug-gacmeedka gaariga, haddii moodooyinka kale loo isticmaalo in lagu beddelo, marka lagu daro korantada magaca ah iyo xuduudaha kale ee la cayimay iyo nidaamiyaha asalka ah waa isku mid. Xakameeyaha beddelka ahi waa inuu la mid noqdaa qaabka birta ee asalka ah, haddii kale, koronto-dhaliyaha waxaa laga yaabaa inuusan si sax ah u shaqeynin wareegga kicinta awgeed.Nidaamiyeyaasha wareegga isku dhafan, waa inay noqdaan kuwo u go'ay oo aan la beddeli karin.

Isticmaal dayactir
Maamulaha guud ahaan looma ogola inuu kala furfuro daboolka inta lagu jiro isticmaalka, xaalada caadiga ahna waa inuu sameeyo kormeer iyo dayactir dhamaystiran 200h ama wax ka badan, nuxurkiisuna waa sida soo socota:
1.Ka saar kiiska oo ka fiiri dusha xidhiidhka ee wasakh iyo dhaawac gubasho.Haddii ay jirto wasakh, ku tirtir dusha xidhiidhka warqad nadiif ah.Haddii xiriirka la jaray ama aan sinneyn oo xiriirku xumaado, guud ahaan waxaa lagu simayaa "00" warqad ciid ah ama xariijimo ciid ah, oo ugu dambeyntii lagu tirtiro warqad nadiif ah.
2. Hubi adkaynta xidhiidhiye kasta, cabbir caabbinta iyo qiimaha caabbinta gariiradda kasta.Haddii uu jiro dhaawac, waa in la hagaajiyo ama lagu beddelaa qayb cusub oo waqti ah.
3.Check danab xidhidhiyaha iyo hadda danbe ee jabiyaha hadda jira,Xaddiga danab yareeya danab,Xaddiga hadda ee xadka hadda joogsiyaha hadda,iyo nusqaaqaha iyo hawada ee xiriirada kala duwan.Haddii ay buuxin waydo shuruudaha, waa in la hagaajiyaa.
4. Hubi maamulaha la hagaajiyay oo fiiro gaar ah u yeelo tilmaanta dallacaadda ammeterka marka aad bilaabayso mishiinka naaftada.Haddii cirbadda ammeter-ka ay weli tilmaamayso dhinaca "-" marka mishiinka naaftada uu ku socdo xawaare dhexdhexaad ah ama ka sarreeya, tani waxay ka dhigan tahay in xidhiidhka cirifka hadda aan la jarin, iyo wareegga dhulka waa in si degdeg ah loo gooyaa;Haddii kale, waxay dhaawici doontaa batteriga, nidaamiyaha, koronto-dhaliyaha, iwm. Haddii irbadda ammeter-ka ay weli tilmaamayso "0" ka dib marka mashiinka naaftada uu bilaabo xawaaraha la qiimeeyay, hagaajinta sharaxaadda aan la hagaajin sida waafaqsan shuruudaha farsamada. , waana in dib loo hubiyaa oo la hagaajiyaa.
