Yadda ake Gwada Stator tare da Multimeter (Jagorar Gwajin Hanya 3)
Abubuwa
Alternator, wanda ya ƙunshi stator da rotor, yana ƙarfafa injin ta hanyar canza makamashin injin zuwa wutar lantarki kuma yana cajin baturi. Don haka, idan wani abu yayi kuskure tare da stator ko rotor, motarka zata sami matsala koda baturin yana da kyau.
Duk da cewa rotor din abin dogaro ne, amma ya fi saurin gazawa saboda yana dauke da coils na stator da wayoyi. Saboda haka, duba stator tare da mai kyau multimeter mataki ne mai mahimmanci a cikin matsala masu canzawa.
Matakan da ke biyowa zasu taimake ka ka duba stator tare da multimeter na dijital.
Yadda za a duba stator tare da multimeter?
Idan kuna fuskantar matsalar cajin motarku ko babur, lokaci yayi da zaku fitar da DMM naku.
Na farko, saita DMM zuwa ohms. Haka kuma, lokacin da ka taɓa wayoyi na mita, allon ya kamata ya nuna 0 ohms. Bayan shirya DMM, gwada baturin tare da jagorar mita.
Idan DMM tana karantawa a kusa da 12.6V, baturin ku yana da kyau kuma matsalar tana da yuwuwar tare da na'ura mai kwakwalwa ko stator waya. (1)
Akwai hanyoyi guda uku don gwada stators:
1. Stator static gwajin
Ana ba da shawarar gwajin tsaye idan kuna fuskantar matsala wajen cajin motarku ko babur. Hakanan, wannan shine kawai gwajin da zaku iya gudanarwa lokacin da motarku ba zata fara ba. Kuna iya cire stator daga injin mota ko gwada shi a cikin injin kanta. Amma kafin a duba juriya dabi'u da kuma duba ga takaice a cikin stator wayoyi, tabbatar da mota a kashe. (2)
A cikin gwajin static stator, ana yin matakai masu zuwa:
(a) Kashe injin
Don duba stators a yanayin tsaye, dole ne a kashe injin. Kamar yadda aka fada a baya, idan abin hawa ba zai fara ba, gwajin stator shine hanya daya tilo don gwada stators.
(b) Saita multimeter
Saita multimeter zuwa DC. Saka baƙar gubar na multimeter a cikin baƙar fata COM jack, wanda ke nufin gama gari. Jar waya za ta shiga cikin jan Ramin tare da "V" da "Ω" alamomin. Tabbatar cewa ba a toshe jajayen waya cikin mahaɗin Ampere ba. Ya kamata kawai ya kasance a cikin Ramin Volts/Resistance.
Yanzu, don gwada ci gaba, kunna maɓallin DMM kuma saita shi zuwa alamar ƙara kamar yadda za ku ji ƙara don tabbatar da cewa komai yayi daidai da kewayawa. Idan baku taɓa amfani da multimeter ba a baya, da fatan za a karanta littafin mai amfani kafin amfani da shi.
(c) Gudanar da gwaji a tsaye
Don duba ci gaba, saka duka biyun binciken multimeter a cikin kwas ɗin stator. Idan kun ji ƙara, da'irar tana da kyau.
Idan kana da stator mai hawa uku, kana buƙatar yin wannan gwajin sau uku, saka na'urorin multimeter a cikin lokaci 1 da Fase 2, Phase 2 da Fase 3, sannan Phase 3 da Fase 1. Idan stator yana da kyau, zaka iya. ya kamata a ji ƙara a kowane yanayi.
Mataki na gaba shine bincika guntun cikin stator. Cire waya ɗaya daga soket ɗin stator kuma taɓa igiyar stator, ƙasa ko chassis na abin hawa. Idan babu siginar sauti, to babu gajeriyar kewayawa a cikin stator.
Yanzu, don bincika ƙimar juriya, saita kullin DMM zuwa alamar Ω. Saka jagorar multimeter a cikin kwas ɗin stator. Ya kamata karatun ya kasance tsakanin 0.2 ohms da 0.5 ohms. Idan karatun ya fita daga wannan kewayon ko kuma yayi daidai da rashin iyaka, wannan alama ce bayyananne na gazawar stator.
Muna ba ku shawarar karanta littafin sabis na abin hawa don sanin ingantaccen karatu.
2. Stator dynamic test
Ana yin gwajin stator mai ƙarfi kai tsaye akan abin hawa kuma yana goyan bayan multimeter a yanayin AC. Wannan yana gwada rotor, wanda ya ƙunshi maganadisu kuma yana juyawa a kusa da stator. Don yin gwajin stator mai ƙarfi, ana aiwatar da matakai masu zuwa:
(a) Kashe wuta
Bi wannan hanya kamar na gwajin tsaye, saka jagorar multimeter a cikin kwas ɗin stator. Idan stator yana da matakai uku, dole ne a yi wannan gwajin sau uku ta hanyar shigar da bincike a cikin kwasfa na lokaci na 1 da na 2, lokaci na 2 da na 3, lokaci na 3 da lokaci na 1. Tare da kunnawa, kada ku ɗauka. duk wani karatu lokacin yin wannan gwajin.
(b) Kunnawa tare da kunna wuta
Fara injin kuma maimaita kunnawar da ke sama don kowane nau'i biyu na matakai. Multimeter ya kamata ya nuna karatun kusan 25V.
Idan karatun kowane nau'i na nau'i biyu sun yi ƙasa sosai, a ce a kusa da 4-5V, wannan yana nufin akwai matsala tare da ɗayan matakan kuma lokaci ya yi da za a maye gurbin stator.
(c) Ƙara saurin injin
Bita injin, ƙara rpm zuwa kusan 3000 kuma sake gwadawa. Wannan lokacin multimeter ya kamata ya nuna darajar kimanin 60 V, kuma zai karu tare da adadin juyin juya hali. Idan karatun yana ƙasa da 60V, matsalar tana tare da rotor.
(d) Gwajin gyara gyara
Mai sarrafawa yana kiyaye ƙarfin lantarki da stator ke samarwa ƙasa da amintaccen iyaka. Haɗa stator ɗin motar ku zuwa mai tsarawa kuma saita DMM don bincika amps akan mafi ƙanƙanta sikelin. Kunna wuta da duk masu kunna wuta kuma cire haɗin kebul ɗin baturi mara kyau.
Haɗa jagorar DMM a cikin jerin tsakanin madaidaicin sandar baturi da madaidaicin sandar. Idan duk gwaje-gwajen da suka gabata sun yi kyau, amma multimeter ya karanta ƙasa da 4 amps yayin wannan gwajin, mai daidaitawa ya yi kuskure.
3. Duba gani
A tsaye da tsauri hanyoyi biyu ne don gwada stators. Amma, idan kun ga alamun alamun lalacewa ga stator, alal misali idan ya ga ya ƙone, wannan alama ce ta mummunan stator. Kuma ba kwa buƙatar multimeter don wannan.
Kafin ka je, za ka iya duba sauran koyawa a kasa. Sai labarinmu na gaba!
