Momwe Mungayesere Stator ndi Multimeter (3-Way Testing Guide)
Zamkatimu
Alternator, yomwe ili ndi stator ndi rotor, imapatsa mphamvu injiniyo posintha mphamvu zamakina kukhala magetsi komanso kulipiritsa batire. Ndichifukwa chake, ngati chinachake chikulakwika ndi stator kapena rotor, galimoto yanu idzakhala ndi mavuto ngakhale batire ili bwino.
Ngakhale rotor ndi yodalirika, imakhala yovuta kwambiri chifukwa imakhala ndi ma stator coils ndi mawaya. Chifukwa chake, kuyang'ana stator ndi ma multimeter abwino ndi gawo lofunikira pakuwongolera ma alternators.
Zotsatirazi zidzakuthandizani kuyesa stator ndi multimeter ya digito.
Momwe mungayang'anire stator ndi multimeter?
Ngati mukuvutika kulipiritsa galimoto kapena njinga yamoto, ndi nthawi yoti mutulutse DMM yanu.
Choyamba, ikani DMM kukhala ohms. Komanso, mukakhudza mawaya a mita, chinsalucho chiyenera kusonyeza 0 ohms. Pambuyo pokonzekera DMM, yesani batire ndi mayendedwe a mita.
Ngati DMM imawerenga mozungulira 12.6V, batire yanu ndiyabwino ndipo vuto limakhala ndi koyilo ya stator kapena waya wa stator. (1)
Pali njira zitatu zoyesera ma stators:
1. Stator static test
Kuyesa static kumalimbikitsidwa ngati mukuvutika kulipiritsa galimoto kapena njinga yamoto. Komanso, awa ndi mayeso okhawo mukhoza kuthamanga pamene galimoto yanu sangayambe. Mutha kuchotsa stator ku injini yagalimoto kapena kuyesa mu injini yokha. Koma musanayang'ane kukana ndikuyang'ana zazifupi mu mawaya a stator, onetsetsani kuti galimotoyo yazimitsidwa. (2)
Pakuyesa kwa static stator, njira zotsatirazi zimachitika:
(a) Zimitsani injini
Kuti muwone ma stators mu static mode, injini iyenera kuzimitsidwa. Monga tanenera kale, ngati galimoto siyamba, stator static test ndiyo njira yokhayo yoyesera ma stators.
(b) Konzani ma multimeter
Khazikitsani multimeter kukhala DC. Ikani chotsogolera chakuda cha multimeter mu jack yakuda ya COM, kutanthauza Common. Waya wofiira adzalowa mu kagawo kofiira ndi zizindikiro "V" ndi "Ω". Onetsetsani kuti waya wofiyira sanalowetsedwe mu cholumikizira cha Ampere. Iyenera kukhala pagawo la Volts/Resistance.
Tsopano, kuti muyese kupitiriza, tembenuzirani knob ya DMM ndikuyiyika ku chizindikiro cha beep pamene mudzamva beep kuti muwonetsetse kuti zonse zili bwino ndi dera. Ngati simunagwiritsepo ntchito ma multimeter, chonde werengani buku la ogwiritsa ntchito musanagwiritse ntchito.
(c) Yesani kuyesa kosasintha
Kuti muwone kupitiliza, ikani ma probe onse a multimeter muzitsulo za stator. Mukamva beep, derali ndilabwino.
Ngati muli ndi stator ya magawo atatu, muyenera kuchita mayeserowa katatu, ndikuyika ma probes a multimeter mu gawo 1 ndi gawo 2, gawo 2 ndi gawo 3, ndiyeno gawo 3 ndi gawo 1. Ngati stator ili bwino, inu ayenera kumva beep muzochitika zonse.
Chotsatira ndicho kufufuza mwachidule mkati mwa stator. Chotsani waya umodzi pa soketi ya stator ndikukhudza koyilo ya stator, pansi kapena chassis yagalimoto. Ngati palibe chizindikiro chomveka, ndiye kuti palibe dera lalifupi mu stator.
Tsopano, kuti muwone mayendedwe okana, ikani kowuni ya DMM ku chizindikiro cha Ω. Ikani ma multimeter otsogolera muzitsulo za stator. Kuwerenga kuyenera kukhala pakati pa 0.2 ohms ndi 0.5 ohms. Ngati kuwerengako kuli kosiyana ndi izi kapena kuli kofanana ndi zopanda malire, ichi ndi chizindikiro chodziwika bwino cha kulephera kwa stator.
Tikukulangizani kuti muwerenge buku la ntchito yagalimoto yanu kuti mudziwe zowerengera zotetezeka.
2. Mayeso amphamvu a Stator
Mayeso amphamvu a stator amachitidwa mwachindunji pagalimoto ndipo amathandizira ma multimeter mu AC mode. Izi zimayesa rotor, yomwe ili ndi maginito ndipo imazungulira mozungulira stator. Kuti muyese mayeso a dynamic stator, zotsatirazi zimachitika:
(a) Zimitsa moto
Kutsatira njira yofananira ndi kuyesa kwa static, ikani ma multimeter otsogolera muzitsulo za stator. Ngati stator ili ndi magawo atatu, mayeserowa ayenera kuchitidwa katatu poyika zofufuza muzitsulo za gawo 1 ndi gawo 2, gawo 2 ndi gawo 3, gawo 3 ndi gawo 1. Ndi kuyatsa, musatenge. kuwerenga kulikonse pochita mayesowa.
(b) Kuyatsa ndi switch yoyatsira
Yambitsani injini ndikubwereza kuyatsa pamwambapa pagawo lililonse. Multimeter iyenera kuwonetsa kuwerenga pafupifupi 25V.
Ngati mawerengedwe a magawo awiri aliwonse ali otsika kwambiri, tinene mozungulira 4-5V, zikutanthauza kuti pali vuto ndi gawo limodzi ndipo ndi nthawi yoti musinthe stator.
(c) Wonjezerani liwiro la injini
Sinthani injini, onjezerani rpm mpaka pafupifupi 3000 ndikuyesanso. Panthawiyi multimeter iyenera kusonyeza mtengo wa 60 V, ndipo idzawonjezeka pamodzi ndi chiwerengero cha kusintha. Ngati kuwerenga kuli pansi pa 60V, vuto liri ndi rotor.
(d) Kuyesa kwa regulator rectifier
Wowongolera amasunga voteji yopangidwa ndi stator pansi pa malire otetezeka. Lumikizani stator yagalimoto yanu ku chowongolera ndikukhazikitsa DMM kuti iwonetse ma amps pamlingo wotsika kwambiri. Yatsani zoyatsira ndi zoyatsira zonse ndikudula chingwe cha batri choyipa.
Lumikizani DMM kutsogolera mndandanda pakati pa mtengo woipa wa batri ndi mtengo woipa. Ngati mayesero onse am'mbuyomu anali abwino, koma ma multimeter amawerenga zosakwana 4 amps panthawi ya mayeserowa, regulator rectifier ndi yolakwika.
3. Kuyang'anitsitsa
Static ndi dynamic ndi njira ziwiri zoyesera ma stators. Koma, ngati muwona zizindikiro zoonekeratu zowonongeka kwa stator, mwachitsanzo ngati zikuwoneka kuti zatenthedwa, ichi ndi chizindikiro chodziwika bwino cha stator yoipa. Ndipo simukusowa multimeter pa izi.
Musanapite, mukhoza onani maphunziro ena pansipa. Mpaka nkhani yathu yotsatira!
