Yadda Ake Gwaji Sensor Hall Tare da Multimeter (Jagora)

Rashin ƙarfi, ƙara mai ƙarfi, da jin cewa injin ɗin yana kulle ta wata hanya alamu ne da ke nuna ko dai kuna mu'amala da mataccen mai kula da ku ko kuma na'urori masu ɗaukar hoto a cikin injin ku. 

Bi waɗannan matakan don gwada firikwensin tasirin Hall tare da multimeter.

Na farko, saita DMM zuwa wutar lantarki na DC (20 volts). Haɗa baƙar gubar na multimeter zuwa baƙar fata na firikwensin zauren. Dole ne a haɗa tashar tashar ja zuwa kyakkyawar jan waya na ƙungiyar firikwensin Hall. Ya kamata ku sami karatun 13 volts akan DMM. Ci gaba don duba fitowar wasu wayoyi.

Na'urar firikwensin Hall shine transducer wanda ke haifar da ƙarfin fitarwa don amsawa ga filin maganadisu. A cikin wannan labarin, za ku koyi yadda ake gwada firikwensin Hall tare da multimeter.    

Me zai faru lokacin da na'urori masu auna firikwensin Hall suka kasa?

Rashin gazawar na'urori masu auna firikwensin zauren yana nufin cewa mai sarrafawa (alamar da ke iko da sarrafa motar) ba ta da mahimman bayanan da ake buƙata don daidaita ƙarfin motar yadda ya kamata. Motar tana aiki da wayoyi guda uku (phases). Matakan uku suna buƙatar lokacin da ya dace ko kuma motar zata makale, ta rasa ƙarfi kuma ta yi sauti mai ban haushi.

Kuna zargin cewa na'urori masu auna firikwensin ku na Hall ba daidai ba ne? Kuna iya gwadawa da multimeter ta bin waɗannan matakai guda uku.

1. Cire haɗin kuma tsaftace firikwensin

Mataki na farko ya haɗa da cire firikwensin daga shingen Silinda. Hattara da datti, guntun karfe da mai. Idan ɗaya daga cikin waɗannan akwai, share su.

2. Camshaft firikwensin / wurin firikwensin crankshaft

Yi nazarin tsarin injin don nemo firikwensin camshaft ko firikwensin matsayi na crankshaft a cikin tsarin sarrafa lantarki (ECM) ko firikwensin camshaft. Sa'an nan kuma taɓa ƙarshen waya mai tsalle zuwa wayar sigina kuma ɗayan ƙarshen zuwa ƙarshen binciken tabbatacce. Binciken mara kyau dole ne ya taɓa ƙasan chassis mai kyau. Yi la'akari da yin amfani da tsalle-tsalle na kada lokacin haɗa madaidaicin jagorar gwajin zuwa ƙasan chassis - idan an buƙata.

3. Karatun ƙarfin lantarki akan multimeter na dijital

Sannan saita multimeter na dijital zuwa ƙarfin DC (20 volts). Haɗa baƙar gubar na multimeter zuwa baƙar fata na firikwensin zauren. Dole ne a haɗa tashar tashar ja zuwa kyakkyawar jan waya na ƙungiyar firikwensin Hall. Ya kamata ku sami karatun 13 volts akan DMM.

Ci gaba don duba fitowar wasu wayoyi.

Sa'an nan kuma haɗa baƙar fata na multimeter zuwa baƙar fata na kayan haɗin waya. Jajayen waya na multimeter yakamata ya taɓa koren waya akan kayan haɗin waya. Bincika idan ƙarfin lantarki yana nuna volts biyar ko fiye. Lura cewa ƙarfin lantarki ya dogara da shigar da kewaye kuma yana iya bambanta daga wannan na'ura zuwa wata. Koyaya, yakamata ya zama mafi girma fiye da sifili volts idan na'urar firikwensin Hall ɗin yayi kyau.

A hankali matsar da maganadisu a kusurwoyi daidai zuwa gaban mai rikodin. Duba abin da ke faruwa. Yayin da kake kusa da firikwensin, ƙarfin lantarki ya kamata ya karu. Yayin da kake tafiya, ƙarfin lantarki ya kamata ya ragu. Na'urar firikwensin crankshaft ɗin ku ko haɗin gwiwar sa ba daidai ba ne idan babu canji a wutar lantarki.

Don taƙaita

Na'urori masu auna firikwensin zaure suna ba da fa'idodi masu yawa kamar amincin da ake buƙata, babban aiki mai sauri, da abubuwan da aka riga aka tsara na lantarki da kusurwoyi. Masu amfani kuma suna son sa saboda ikonsa na aiki a cikin kewayon zafin jiki daban-daban. Ana amfani da su sosai a cikin motocin tafi-da-gidanka, na'urori masu sarrafa kansu, kayan sarrafa ruwa, injinan noma, yankan da injin sake jujjuyawa, da injin sarrafawa da tattara kaya. (1, 2, 3)
