Yiziphi izintambo ezi-2 ku-alternator?

Okuqukethwe

Imidwebo yokuxhuma ijeneretha yemoto
Ijeneretha yemoto isebenza kanjani?

Ngakho-ke uhlangane nezintambo ezimbili ku-alternator yakho futhi uyazibuza ukuthi ngezanzani.

Ama-alternator anezintambo ezimbili awavamisile ukusetshenziswa ezimotweni zesimanje, njengoba ama-alternator anezintambo ezintathu noma ezine evamise ukufakwa. Ukuze uhlukanise phakathi kwalezi zintambo, uzodinga ukuzijwayeza ngemidwebo yokuxhuma kwe-alternator, esizoyichaza ngezansi.

Ake sibhekisise...

Imidwebo yokuxhuma ijeneretha yemoto

Uma ubheka i-generator, uzobona izintambo ezimbili kuphela: ikhebula lamandla kanye nentambo yokuvusa. Nokho, i-alternator inesistimu yezintambo eyinkimbinkimbi njengoba ixhuma izingxenye eziningi ezahlukene. Nginikeza umdwebo wokuxhumeka kwejeneretha ngezansi. Manje ake sibheke lokhu kuxhumana:

Umdwebo wezintambo ezishintshashintshayo ezi-3

Lo mdwebo wokuxhuma okuguquguqukayo wezintambo ezi-XNUMX ubonisa ukuxhumana phakathi kwezingxenye ezihlukene zesekethe.

Izintambo ezintathu eziyinhloko ezakha isekethe yikhebula lebhethri elihle, inzwa ye-voltage, kanye nentambo yokufaka yokuthungela. Kukhona futhi ukuxhumana phakathi kwenjini kanye nentambo yokufaka ignition. Ngenkathi iwaya ethola amandla kagesi izwa, ixhuma amandla kusilungisi, idlulisa amandla ukusuka enjini ukuya ku-alternator.

Lawa ma-alternator anemisebenzi eminingi ahlanganisa izilungisi ezakhelwe ngaphakathi zokulawula amandla.

Bangakwazi ukuhlinzeka futhi balungise okwamanje kumjikelezo ofanayo, ngokungafani nama-alternator ocingo olulodwa. Zonke izingxenye zizothola i-voltage elawulwayo uma usebenzisa i-generator enezintambo ezintathu.

Isilawuli sangaphandle se-electromechanical voltage

Ikhebula lenzwa kagesi lifakwa kuzibuthe kagesi izilawuli ezihamba ngezimoto.

Lokhu kwakha insimu kazibuthe ezungeze uzibuthe, idonsela insimbi iqonde ngakuyo. Eziyingini ezinjalo kukhona ukushintshwa kwe-electromagnetic - i-relay yohambo, isilawuli kanye nesilawuli samanje. Isiguquli kanye neswishi yesilawuli esikhona zilawula i-voltage ephumayo ngokulawula isekethe evusa amadlingozi ye-alternator, kuyilapho i-relay yokunqamula ixhumanisa ibhethri nejeneretha.

Kodwa-ke, ngenxa yendlela yokudlulisela engasebenzi kahle, amasekhethi e-electromechanical awavamile ukusetshenziswa ezimotweni namuhla, nakuba ebaluleke kakhulu kumasekethe okulawula i-AC.

Umdwebo wezintambo olawulwa yi-PCM

I-alternator esebenzisa amamojula angaphakathi ukuze ilawule isekethe ye-excitation yaziwa ngokuthi i-powertrain control module voltage regulation circuit.

I-PCM ilawula ukugeleza kwamanje ngokuhlaziya idatha evela kumojula yokulawula umzimba (BCM) futhi ihlaziye izidingo zokushaja zesistimu.

Amamojula acushiwe uma i-voltage iwela ngaphansi kwezinga elifanele, okuthi ngokuhamba kwesikhathi liguqule ukugeleza kwamanje ngekhoyili.

Ngenxa yalokho, ishintsha ukuphuma kwesistimu ngokwezidingo zayo. Ama-alternator alawulwa nge-PCR alula kodwa asebenza kahle ngendlela emangalisayo ekukhiqizeni amandla kagesi adingekayo.

Ijeneretha yemoto isebenza kanjani?

Ukusebenza kwejeneretha kulula ukukuqonda.

I-generator iboshwe ngebhande le-V-ribbed, igqoke i-pulley. I-pulley iyazungeza futhi izungezisa ama-rotor shafts e-generator lapho injini isebenza. I-rotor iyizibuthe kagesi enamabhulashi ekhabhoni kanye nezindandatho ezimbili eziphendukayo zensimbi ezixhunywe ku-shaft yayo. Inikeza ugesi omncane ku-rotor njengomkhiqizo wokujikeleza futhi idlulisela amandla ku-stator. (1)

Ozibuthe bagijima phakathi kwezihibe zentambo yethusi ku-alternator ye-stator ku-rotor. Ngenxa yalokho, kwakha insimu kazibuthe ezungeze amakhoyili. Lapho insimu kazibuthe iphazamiseka njengoba i-rotor ijikeleza, idala ugesi. (2)

Isilungisi se-alternator diode sithola i-AC kodwa kufanele siguqulelwe ku-DC ngaphambi kokusetshenziswa. I-current yezindlela ezimbili iguqulwa isilungisi sibe indlela eyodwa egeleza yamanje eqondile. I-voltage ibe isisetshenziswa kusilawuli se-voltage, esilawula i-voltage ngokuya ngezidingo zezinhlelo ezahlukahlukene zezimoto.
