DUBI NOZZLES ALLURAR: MATSALOLIN

Ana iya yin matsala duka lokacin da injin ke aiki da kuma lokacin da aka kashe shi.

1 Karanta kuma kwatanta ƙarfin lantarki da tsawon lokacin bugun jini

Ana iya nuna siginar allurar ta amfani da oscilloscope. Don wannan dalili, haɗa layin aunawa zuwa layin siginar, da ɗayan layin zuwa fil ɗin ƙasa mai dacewa. Tare da injin yana gudana, yana yiwuwa a karanta kashe wutar lantarki da lokacin bugun jini (lokacin buɗewa) daga tsarin siginar. Lokacin buɗe bawul ɗin maƙura, lokacin bugun bugun jini dole ne ya ƙaru yayin lokacin haɓakawa, kuma tare da saurin injuna akai-akai (kusan 3000 RPM) dole ne ya koma baya, ko a ƙasa, ƙimar mara amfani. Za'a iya kwatanta sakamakon kowane silinda da juna, kuma wannan na iya ba da alamar kurakurai, misali ƙarancin wutar lantarki.

2 Auna matsin man fetur da kuma duba tsarin sha da shaye-shaye don ɓangarori

Sauran gwaje-gwaje masu mahimmanci suna auna matsi na man fetur, don gano wasu abubuwan da za su iya yin kuskure (famfofin mai, tace mai, mai sarrafa matsa lamba), da kuma duba tsarin ci da shaye-shaye don ɗigogi, don hana sakamakon auna karya. Idan firikwensin yana da haɗin haɗin-pin-2, yana yiwuwa ya zama firikwensin inductive. A wannan yanayin, juriya na ciki, yuwuwar gajeriyar kewayawa zuwa firam, da siginar za'a iya ƙayyade.

Don yin wannan, cire haɗin toshe kuma duba juriya na ciki na firikwensin. Idan ƙimar juriya ta ciki ta kasance 200 zuwa 1,000 ohms (dangane da ƙimar tunani), firikwensin yana da kyau. Idan darajar ta kasance 0 ohms, akwai gajeren kewayawa, kuma a cikin yanayin akwai hutu. Ana yin gwajin gajeriyar da'ira zuwa firam ta amfani da ohmmeter daga fil ɗin haɗi zuwa abin hawa

ƙasa. Ƙimar juriya dole ne ta karkata zuwa ga rashin iyaka. Gwajin ta amfani da oscilloscope dole ne ya haifar da siginar sinus na isasshen ƙarfi. A yanayin janareta na Hall, kawai ƙarfin sigina a cikin siginar siginar murabba'i da ƙarfin wutar lantarki ne kawai za a gwada. Wannan dole ne ya haifar da siginar raƙuman murabba'i dangane da saurin injin. Ya kamata mu maimaita a wannan lokacin cewa yin amfani da ohmmeter na iya lalata janareta na Hall.
