I-Solenoid: ukusebenza nokusetshenziswa

Un i-solenoid noma i-bobbin iyintambo yensimbi eboshiwe. Ngokudlula amandla kagesi kuwo, ikhiqiza insimu kazibuthe evame ukusetshenziselwa ukuheha isilinda sensimbi phakathi nendawo. Emotweni, ama-solenoid akhona ezingxenyeni eziningi ezibalulekile, njengama-injection noma izilawuli ze-electronic fuel pressure.

Kodwa-ke, igama elithi solenoid livame ukusetshenziselwa ukubhekisela kulelo elitholakala ku- i-Starter motor, eyaziwa nangokuthi i-contactor, i-auto, i-traction relay, i-traction solenoid, i-automotive solenoid noma i-starter relay. Ibuye ngezinye izikhathi (ngephutha) ibizwa ngokuthi i-Bendix, ngoba ishayela uhlelo lwe-Bendix.

Yini i-solenoid?

Ukuze uqonde kangcono ukuthi i-solenoid iyini, kuhle ukuyiqhathanisa ne-a ugesi kagesi. Lokhu kuhlanganisa a intambo ejwayelekile okudlula khona manje yagingqika yaba ucezu lwensimbi. Ngendlela yokuthi ifinyelela insimu efanayo kazibuthe njengozibuthe.

Awu, a i-solenoid Imayelana ne- i-electromagnetic ngaphandle kwe-iron core. Okuthile okwenza buthaka insimu kazibuthe ngandlela-thile, kodwa ivumela okuhehayo kufinyelela enkabeni yakho. Uma sibeka ucezu lwensimbi kwelinye lezinhlangothi, i-solenoid izoyikhanga kuze kube yilapho ingaphakathi kwayo, njengoba uzokwazi ukubona ngezansi, ku-starter motor.

Isebenza kanjani i-starter motor solenoid?

Isiqalisi siyisici kubalulekile injini, njengoba iphethe ukuqala ukujikeleza kwayo ngenxa yamandla kagesi webhethri. Lapho i-crankshaft iqala ukuphenduka futhi amasilinda eqala ukushaywa kwawo okuhambisanayo, ukuqhuma okuvumela injini ukuba izisebenzele ngokwayo kukhiqizwa. Yilapho umsebenzi we-starter motor uphela khona.

Uma siphendulela ukhiye wokuthungela endaweni yokuqala, sithumela ugesi usuka kubhethri ngesixhumi esixhumene naye uye kusiqalisi solenoid. Lokhu kagesi edlula solenoid we i-Starter motor yakha a amandla kazibuthe edonsa isilinda phakathi nendawo. Lokhu kunyakaza komugqa kusetshenziselwa imisebenzi emibili:

• Yenza i- i-Starter motor ungaqala ukusebenza ngoba ivala isekethe kagesi ewuphakelayo, okuvumela imoto ukuthi iqale. Ngamanye amazwi, isebenza njenge-relay futhi ihlangana namatheminali amabili, okuyiwo avumela ukudlula kwamandla kagesi ukusuka ku- ibhethri (12V) enjini kagesi ye-starter motor, enesibopho sokukhiqiza amandla adingekayo ukuhambisa i-flywheel futhi iqale injini.
• Phusha iphinikhodi yedrayivu nge i-lever enesibopho sokusunduza iphini lokushayela ye-starter motor futhi uyihlanganise namazinyo we i-flywheel (isithombe ngezansi).

Uma sikhulula ukhiye wokuthungela futhi usuka endaweni yokuqala uye endaweni yokuxhumana, ugesi uyayeka ukudlula ku-solenoid yokuqala, ngakho insimu kazibuthe iyanyamalala futhi zonke izakhi zesiqalisi zibuyele kokujwayelekile. indawo yokuphumula. Njengoba ubona esithombeni, isilinda sensimbi sinomthombo esibuyisela endaweni yawo, ngaphandle kwe-solenoid.

I-athikili ehlobene:

Uyivula futhi uyiqale kanjani imoto uma ingawuboni ukhiye

Amaphutha e-Solenoid emotweni

Uma i-starter motor solenoid ihamba kabi injini ngeke iqale.. Uma imoto ingaqali, kubalulekile ukukhipha kuqala ukuthi ukushaja kwebhethri kuphansi noma hlola ukuthi ibhethri alilungile yini. Into ongayenza kalula nge-a I-multimeter njengoba kubonisiwe ku le vidiyo:

Uma ibhethri lingeyona inkinga, ukuze sikhiphe ukungasebenzi kahle kwe-solenoid singenza ukuhlolwa okulandelayo:

• sizodinga ezinye gxuma iziqeshana zokuqala kanye nebhethri ukuze lihlolwe.
• Sizoxhuma i-negative yebhethri endaweni ye-motor motor ukuze sithole umhlabathi.
• Ngesigxivizo esixhunywe kuphozithivu yebhethri, sizothinta ngobumnene itheminali yokuxhumana ephozithivu ye-solenoid, ngenhloso yokuvala isekethe futhi sivule i-solenoid kuphela, njengoba besingenza uma sizama ukuqalisa ngokhiye wokubasa.
• I-clack-clack kufanele izwakale futhi uma sikhipha isiqalisi, sizobona ukuthi isicoco sayo siya phambili kanjani. Uma lokhu kwenzeka, singakhipha inkinga nge-solenoid.
• Uma yenza umsebenzi wayo uma senza lokhu kuhlolwa kodwa hhayi uma isemotweni, kungenzeka ukuthi inkinga ilele kahle isilinda sokuqala noma kufayela le- i-cabling, okungenzeka yephulwe.

Kwezinye izimoto, uma sivula ukhiye wokushisa sizozwa a umsindo ohamuzelayo ofana nowe "mixer". Kuwuphawu lokuthi i-motor starter motor iyazungeza kodwa i-solenoid ayisebenzi, njengoba esikuzwayo kuthiwa i-motor iyajika ngaphandle komthwalo.

I-solenoid yesilawuli se-Fuel pressure

Njengoba ubona, okuwukuphela kwento eyenziwa yi-solenoid ukufeza ukunyakaza okuqondile ngokuheha ibha yensimbi ngaphakathi kwayo. Lokhu kunokusetshenziswa okuningi ngaphakathi kwemoto noma eminye imishini eminingi. Ngokwesibonelo, ku-a isilawuli sengcindezi kaphethiloli kagesi, leyo nsimbi yensimbi ixhunywe ku-valve. Ngendlela enjalo uma i-solenoid iyidonsa, ivula i-valve ukuze ikhulule ukucindezela futhi uvikele ama-injection.

Ngokwemvelo, ukufeza lo msebenzi, i-solenoid kufanele ihambisane nenzwa, ekala ingcindezi ye uhlelo lomjovo kanye neyunithi yokulawula elawula ukuvulwa noma ukuvala uma kunesidingo.

injector solenoids

Njengoba igama layo libonisa, ku- ama-injection valve solenoid Ngenye yalezi zakhi ezivula futhi zivale i-valve ukuze uphethiloli udlule noma cha. Ukuhlinzwa okuvumelanisa Iyunithi yokulawula injini (ECU ngokwesifinyezo sayo ngesiNgisi) ngokwezidingo zenjini.

Kumjovo we-piezoelectric lo msebenzi uyenziwa i-actuator kanye nomgogodla we-ceramic onwebekayo noma owenza inkontileka nomsinga odlulile kuwo. Okuyinika igama layo le-piezoelectric. Njengoba ukunwetshwa kulolu hlobo lwezinto kushesha kakhulu, kuvumela imijovo kaphethiloli eyengeziwe ngomjikelezo wenjini ngamunye. Ngakolunye uhlangothi, zibiza ngokuphindwe kathathu kunalezo ezisebenza ngama-solenoids.
