Momwe Mungayesere Sensor ya Hall ndi Multimeter (Guide)

Kutaya mphamvu, phokoso lalikulu, ndi kumverera kuti injini yatsekedwa mwanjira ina ndizizindikiro kuti mukuchita ndi chowongolera chakufa kapena masensa a hall effect crank mkati mwa injini yanu. 

Tsatirani izi kuti muyese sensa ya Hall effect ndi multimeter.

Choyamba, ikani DMM ku DC voltage (20 volts). Lumikizani chotsogolera chakuda cha multimeter kupita kutsogolo kwakuda kwa sensa ya holo. Malo ofiira amayenera kulumikizidwa ku waya wofiyira wabwino wa gulu la waya wa Hall sensor. Muyenera kuwerenga ma volts 13 pa DMM. Pitirizani kuyang'ana zotsatira za mawaya ena.

Sensor ya Hall ndi transducer yomwe imapanga mphamvu yamagetsi poyankha maginito. M'nkhaniyi, muphunzira momwe mungayesere sensor ya Hall ndi multimeter.    

Kodi chimachitika ndi chiyani masensa a Hall akalephera?

Kulephera kwa masensa a Hall kumatanthauza kuti woyang'anira (gulu lomwe limapereka mphamvu ndi kuyendetsa galimoto) alibe chidziwitso chofunikira kuti agwirizane bwino mphamvu ya galimotoyo. Galimoto imayendetsedwa ndi mawaya atatu (gawo). Magawo atatuwa amafunikira nthawi yoyenera kapena injini imakakamira, kutaya mphamvu ndikutulutsa mawu okhumudwitsa.

Kodi mukuganiza kuti masensa anu aku Hall ndi olakwika? Mutha kuyesa ndi ma multimeter potsatira njira zitatu izi.

1. Chotsani ndikuyeretsa sensa

Gawo loyamba ndikuchotsa sensor kuchokera pa cylinder block. Chenjerani ndi dothi, tchipisi tachitsulo ndi mafuta. Ngati zina mwa izi zilipo, zichotseni.

2. Camshaft sensor / crankshaft sensor malo

Yang'anani mawonekedwe a injini kuti mupeze sensa ya camshaft kapena crankshaft position sensor mu electronic control module (ECM) kapena camshaft sensor. Kenako gwirani mbali imodzi ya waya wolumphira ku waya wa chizindikiro ndi kumapeto kwina mpaka kumapeto kwa kafukufuku wabwino. Kufufuza kolakwika kumayenera kukhudza malo abwino a chassis. Ganizirani kugwiritsa ntchito chodumpha chodumpha cha ng'ona polumikiza njira yoyezetsa yolakwika ku malo a chassis - ngati pangafunike.

3. Kuwerengera magetsi pa multimeter ya digito

Kenako ikani multimeter ya digito ku DC voltage (20 volts). Lumikizani kutsogolo kwakuda kwa ma multimeter kupita kutsogolo kwakuda kwa sensa ya holo. Malo ofiira ayenera kulumikizidwa ku waya wofiyira wabwino wa gulu la waya wa Hall sensor. Muyenera kuwerenga ma volts 13 pa DMM.

Pitirizani kuyang'ana zotsatira za mawaya ena.

Kenako gwirizanitsani waya wakuda wa multimeter ku waya wakuda wa waya wazitsulo. Waya wofiira wa multimeter uyenera kukhudza waya wobiriwira pazingwe zomangira. Onani ngati magetsi akuwonetsa ma volts asanu kapena kuposerapo. Dziwani kuti voteji zimadalira athandizira dera ndipo akhoza amasiyana chipangizo china. Komabe, ziyenera kukhala zazikulu kuposa zero volts ngati masensa a Hall ali bwino.

Pang'onopang'ono sunthani maginito pamakona akumanja kupita kutsogolo kwa encoder. Onani zomwe zikuchitika. Pamene mukuyandikira sensa, mphamvu yamagetsi iyenera kuwonjezeka. Pamene mukuyenda, mphamvu yamagetsi iyenera kuchepa. Sensa yanu ya crankshaft kapena maulumikizidwe ake ndi olakwika ngati palibe kusintha kwamagetsi.

Kufotokozera mwachidule

Masensa akunyumba amapereka maubwino ambiri monga kudalirika kofunikira, kuthamanga kwambiri, komanso zotulutsa zamagetsi zomwe zidakonzedweratu ndi ma angles. Ogwiritsanso amachikonda chifukwa cha luso lake logwira ntchito zosiyanasiyana kutentha. Amagwiritsidwa ntchito kwambiri pamagalimoto am'manja, zida zamagetsi, zida zogwirira ntchito zam'madzi, makina aulimi, makina odulira ndi obwezeretsa, komanso makina opangira ndi kunyamula.

Onani zina mwazolemba zathu pansipa.

• Momwe mungayesere capacitor ndi multimeter
• Momwe mungayang'anire sensor ya crankshaft yokhala ndi multimeter
• Momwe mungayesere sensa ya crankshaft yamawaya atatu ndi multimeter
