Ungahlola kanjani isilawuli se-voltage (i-manual)

Okuqukethwe

Amathuluzi Okuhlola I-Automotive Voltage Regulator
Indlela yoku-1: Hlola i-Car Voltage Regulator
Indlela yesi-2: Ukuhlola isilawuli se-voltage esinamaphini amathathu

Ukulawulwa kwamandla kagesi kubalulekile kunoma yiluphi uhlelo lukagesi. Ngaphandle kokulawulwa kwamandla kagesi noma ukuba khona kwesilawuli sikagesi, i-voltage efakwayo (phezulu) ilayisha kakhulu amasistimu kagesi. Izilawuli zamandla kagesi zisebenza ngendlela efanayo nezilawuli zomugqa.

Baqinisekisa ukuthi ukuphuma kwejeneretha kulawula i-voltage yokushaja ngaphakathi kwebanga elishiwo. Ngakho, zivimbela ukunyuka kwamandla ohlelweni lukagesi lwemoto.

Unalokhu emqondweni, kubalulekile ukuthi uhlole njalo isimo se-voltage regulator yemoto yakho.

Kulo mhlahlandlela, ngizokukhombisa yonke inqubo isinyathelo nesinyathelo. Sicela uyifunde kuze kube sekupheleni futhi uzofunda ukuthi ungahlola kanjani isilawuli se-voltage nge-multimeter.

Ngokuvamile, ukuze uhlole isilawuli sakho se-voltage, setha i-multimeter yakho ukukala ama-volts bese uyixhuma ebhethrini ukuze uhlole i-voltage yayo. Qiniseka ukuthi imoto yakho ivaliwe lapho uhlola umthamo webhethri. Naka ukufundwa kwe-multimeter, okungukuthi, i-voltage yebhethri yakho - i-voltage kufanele idlule i-12V, ngaphandle kwalokho ibhethri lakho lizohluleka. Manje vula injini yemoto yakho. Ukufundwa kwamandla kagesi kufanele kukhuphuke ngaphezu kuka-13V. Uma yehla ngaphansi kuka-13V, isilawuli sikagesi semoto yakho sinenkinga yobuchwepheshe.

Amathuluzi Okuhlola I-Automotive Voltage Regulator

Uzodinga amathuluzi alandelayo ukuze uhlole isilawuli sikagesi semoto yakho:

ibhethri lemoto
I-multimeter yedijithali enama-probe
Izinsimbi zebhethri
Ivolontiya (1)

Indlela yoku-1: Hlola i-Car Voltage Regulator

Manje ake sihlole isimo se-voltage regulator yemoto yakho ngokuyihlola nge-multimeter. Ukuze wenze lesi senzo, kufanele uqale usethe i-multimeter yakho.

Isinyathelo 1: Setha i-multimeter yakho

Indlela Yokuhlola I-Voltage Regulator (Umhlahlandlela)

Vula inkinobho yokukhetha ukuze ulungise i-voltage - lesi sigaba sivame ukubizwa ngokuthi "∆V noma V". Ilebula engu-V ingaba nemigqa eminingi phezulu.
Bese usetha i-multimeter yakho ibe ngu-20V. Ungalimaza isilawuli sakho se-voltage uma i-multimeter yakho isesimweni se-"Ohm Amp".
Faka umthofu obomvu embotsheni ephawulwe ngokuthi V kanye nomthofu omnyama ethekwini ephawulwe ngokuthi COM.
Manje lungisa i-multimeter yakho ngokubheka imikhondo ye-probe. I-multimeter izokhala uma isebenza kahle.

Isinyathelo sesi-2. Manje xhuma umkhondo we-multimeter ebhethri yemoto.

Manje cisha injini yemoto yakho bese uxhuma imikhondo ye-multimeter ngokufanele. I-probe emnyama ixhuma kutheminali yebhethri elimnyama kanye nophenyo olubomvu kutheminali ebomvu.

Udinga ukufunda umthamo webhethri lakho. Izokwazisa uma ibhethri lakho lihluleka noma lisesimweni esikahle.

Ngemuva kokuxhuma ama-probes, funda ukufundwa kwe-multimeter. Inani elitholiwe kufanele ngokwemibandela lidlule ku-12 V uma injini icishiwe. I-12V isho ukuthi ibhethri lilungile. Nokho, amanani aphansi asho ukuthi ibhethri lakho libi. Ishintshe ngebhethri elisha noma elingcono.

Isinyathelo sesi-3: Vula injini

Beka imoto yakho epaki noma engathathi hlangothi. Faka amabhuleki ezimo eziphuthumayo bese uqala injini yemoto. Kulokhu, i-multimeter probes kufanele ihlale inamathele ebhethri yemoto, ngoba lokhu ungasebenzisa izinsimbi zebhethri.

Manje hlola inkomba block of multimeter. Ukufundwa kwamandla kagesi kufanele kukhuphuke ukusuka ku-voltage ephawuliwe (uma imoto icishiwe, i-voltage yebhethri) iye cishe ku-13.8 volts. Inani elingaba ngu-13.8V liyinkomba yempilo yesilawuli sikagesi esiphehla ugesi. Noma yiliphi inani elingaphansi kuka-13.8 lisho ukuthi isilawuli sakho samandla kagesi asisebenzi kahle.

Enye into okufanele uyiqaphele i-voltage ephumayo engaguquki noma eguquguqukayo ephezulu noma ephansi. Kusho futhi ukuthi isilawuli sakho sikagesi asisebenzi kahle.

Isinyathelo sesi-4: RPM imoto yakho

Uzodinga omunye umuntu ozokusiza lapha. Bazophendula injini ngenkathi ulandela ukufundwa kwe-multimeter. Umlingani wakho kufanele kancane kancane andise ijubane ku-1,500-2,000 rpm.

Naka ukufundwa kwe-multimeter. I-voltage regulator esesimweni esihle kufanele ibe nama-volts angaba ngu-14.5. Futhi noma yikuphi ukufunda okungaphezulu kuka-14.5 volts kusho ukuthi isilawuli sakho samandla kagesi sibi.

Indlela yesi-2: Ukuhlola isilawuli se-voltage esinamaphini amathathu

Ukunikezwa kwamandla kwezigaba ezintathu kusebenza ngokushaja ibhethri ukuze ithathe indawo kagesi edonswa uhlelo lukagesi. Ine-input, evamile kanye namabhulokhi okukhiphayo. Iguqula i-alternating current ibe eyamanje eqondile, evame ukutholakala ezithuthuthu. Landela lezi zinyathelo ezingezansi ukuze uhlole i-voltage yezigaba ezintathu zokulungisa kabusha kumatheminali.

Qiniseka ukuthi i-multimeter yakho isasethiwe.
Manje thatha imikhondo yakho ye-multimeter futhi ulinganise i-voltage yesilawuli sakho samandla kagesi sezigaba ezintathu.
Isilawuli sezigaba ezintathu "sinemilenze" emi-3, hlola isigaba ngasinye.
Faka ama-probe emilenzeni ngendlela elandelayo: isilinganiso 1^st umlenze ngo-2^nd eyodwa, 1^st umlenze ngo-3^rd, futhi ekugcineni 2^nd umlenze ngo-3^rdimilenze.

Qaphela ukufundwa kwamamitha amaningi esinyathelweni ngasinye. Kufanele uthole ukufundwa okufanayo kuzo zonke izigaba ezintathu. Kodwa-ke, uma umehluko ekufundweni kwe-voltage ubalulekile, hamba uyolungisa. Lokhu kusho ukuthi i-voltage rectifier yakho yezigaba ezintathu ayisebenzi kahle.
Manje qhubeka futhi uhlole isigaba ngasinye phansi. Kuleli qophelo vele uqiniseke ukuthi kukhona okufundiwe, akukho ukufunda kusho ukuthi kunesixhumanisi esivulekile. (2)
