Momwe mungayesere injini ya fan ndi multimeter

18.02.2023 /

Fan motor resistor ndi yomwe imayang'anira kukankhira mpweya wotentha kudzera m'malo otsegulira nthawi iliyonse mukayatsa makina otenthetsera. Injini imagwira ntchito limodzi ndi makina oziziritsira ndi kutenthetsa agalimoto yanu. Mukawona kumveka kwachilendo kuchokera ku mpweya wabwino, izi zikutanthauza kuti injini ya fan iyenera kuyang'aniridwa.

    Kuchita kukonza kwa ma fan motor ndi ma multimeter kukuthandizani kuzindikira gawolo. Apa ndikutengerani kalozera watsatanetsatane wamomwe mungayesere injini ya fan ndi multimeter.

    Kuyang'ana Ma Fan Motor ndi Multimeter (Masitepe 5)

    Nthawi zambiri mumatha kupeza chosinthira cha fan kuseri kwa bokosi la magolovu mgalimoto yanu. Mukachipeza, tsatirani izi kuti muyese fan motor resistor:

    Khwerero 1: Yesani waya wolakwika ndi njira yabwino ya multimeter.

    Ntchito yoyamba ndikuzimitsa zolipiritsa zabwino ndi zoyipa zamagetsi.

    Kawirikawiri waya wakuda ndi woipa. Koma gwiritsani ntchito chitsogozo chabwino cha multimeter kuyesa chingwe chakuda (choyipa) ndi ma multimeter. Kawirikawiri waya wakuda ndi woipa. Koma gwiritsani ntchito chitsogozo chabwino cha multimeter kuyesa chingwe chakuda (choyipa) ndi ma multimeter.

    Gawo 2: Yatsani injini

    Yambitsani injini pogwiritsa ntchito kiyi yoyatsira kuti muyeze kuchuluka kwa magetsi mu cholumikizira chamagetsi cha fan motor (waya wofiirira).

    Khwerero 3. Khazikitsani multimeter ku mphamvu ya DC ndikuyesa

    Sinthani multimeter kukhala mphamvu ya DC, kenako yatsani chowotcha kapena choyatsira mpweya ndi mphamvu yayikulu.

    Kusintha kwanu kwa fan ndikolakwika ngati multimeter ikuwonetsa kuti palibe mtengo / mtengo. Muyenera kuyang'ananso injini ya fan ngati multimeter ikuwona kuti ilipo.

    Khwerero 4: Onani ngati relay yakhazikika

    Tsopano mu footwell, chotsani chivundikiro chofikira cha fuse, chomwe mungapeze pafupi ndi chosinthira chakumbali chokwera.

    Chotsani cholumikizira choletsa kuphulika mgalimoto. Yang'anani chingwecho ngati chakhazikika kapena osagwiritsa ntchito multimeter (ohm sikelo). Kenako yesani osayika pini yapano pamlingo wa DC wa multimeter.

    Ngati simukuwona zapano, pezani fuse ya IGN pansi pa chivundikirocho, masulani chivundikirocho, ndikulumikiza batire yolakwika ndi ma multimeter. Ngati fuyuziyo iwomberedwa, ndikupangira kuti musinthe.

    Khwerero 5: Yang'anani cholumikizira

    Yang'anani cholumikizira kuti muwonetsetse kuti fuse ikugwira ntchito. Kuyatsa kuyatsa kwagalimoto ndikuyika multimeter ku sikelo ya DC, yang'anani cholumikizira.

    Ngati zonse zikuyenda bwino, relay iyenera kusinthidwa.

    Mafunso ofunsidwa kawirikawiri

    Kodi mungadziwe bwanji ngati injini ya fan iyenera kuyang'aniridwa?

    Ngati mukukumana ndi mavuto ndi makina anu a HVAC, zotsutsa zanu ndizoyipa ndipo ziyenera kusinthidwa. Zina mwa zizindikiro zochenjeza za injini yoyipa ndi izi: (1)

    Mphamvu zamagalimoto za fan sizikugwira ntchito. Ngati mpweya sudutsa muzitsulo pamene choyatsira mpweya kapena chotenthetsera chayatsidwa, chikhoza kusweka. Fani yanu ikalephera, sipadzakhala mpweya wotuluka, womwe umafunika kuunikanso kapena kusinthidwa.

    Kugwiritsa ntchito mphamvu kwa injini ya fan ndikochepa.

    Galimoto yanu ya fan imatha kusweka ngati mpweya wotuluka m'mapaipi anu ndi wopanda pake kapena kulibe. Galimoto ya fan yofooka kapena yowonongeka sichitha kupereka mpweya wokwanira kuti ukhalebe ndi kutentha kwabwino.

    Liwiro la mafani ndilotsika.

    Chizindikiro china cha injini yoyipa yamoto ndikuti injiniyo imangothamanga pa liwiro linalake. Ma injini ambiri amafanizira amapangidwa kuti azithamanga mosiyanasiyana kuti athe kuthana ndi kutentha kosiyanasiyana m'nyumba. Ngati injini ya fan yanu ikulephera kutulutsa mpweya wozizira kapena wofunda pamalo omwe mwatchulidwa, ichi ndi chizindikiro kuti ili ndi vuto. (2)

    Kodi ma fan motors ndi chiyani

    1. Ma motors othamanga amodzi

    Galimoto yamtunduwu imawomba mpweya pa liwiro lokhazikika.

    2. Makina othamanga osinthika

    Galimoto iyi imawomba mpweya pa liwiro losiyanasiyana.

    Onani zina mwazolemba zathu pansipa.

    • Momwe mungayesere capacitor ndi multimeter
    • Momwe mungayesere magetsi a DC ndi multimeter
    • Momwe mungayang'anire jenereta ndi multimeter
