Kodi kufufuza injini multimeter: sitepe ndi sitepe malangizo ndi malangizo

Nthawi zambiri funso n'lakuti, mmene kukayendera galimoto pambuyo kulephera, ndipo pambuyo kukonza, ngati sasiya. Pali njira zingapo: Kupenda zakunja kumbali wapadera, "kupitiriza" kumulowetsa multimeter. The njira yamasika kwambiri ndalama ndi ntchito zake zosiyanasiyana, koma amapereka zotsatira zolondola si nthawi zonse. Ambiri postoyannikov kumulowetsa kukana pafupifupi ziro. Choncho, circuitry zina zomwe zingafunike choyezera lapansi.

mota kapangidwe

Mwamsanga kuphunzira mmene kukayendera galimoto, muyenera kukhala bwino za mfundo zazikulu chipangizo. Maziko a Motors zonse ndi mbali ziwiri kapangidwe: a ozungulira ndi stator. The chigawo choyamba nthawi zonse zimayenda mchikakamizo cha munda atomu, ndi n'kupuma chachiwiri ndi monga amalenga mmene kanyamaka otaya.

Kumvetsa mmene kukayendera galimoto, muyenera kamodzi kuti manja ake. Osiyana zaphindu opanga osiyana, koma matenda a mbali magetsi cha mfundo mpaka amakhalabe sichinasinthe. Pakati pa ozungulira ndi stator kusiyana imene zingaunjikane swarf pa nyumba kumasula.

Mayendedwe pa avale zingabweretse kwambiri zizindikiro panopa, chifukwa chitetezo amakugwetsa. Kusanthula funso mmene kukayendera galimoto, musati muyiwale za kuwonongeka mawotchi mbali chikusuntha Borno kumene ojambula ali.

mavuto matenda

Pamaso cheke galimoto multimeter, kunyamula kunja yoyendera thupi yozizira impeller, onani kutentha manja wokhudza zitsulo pamalo. The nyumba mkangano amasonyeza panopa overvalued chifukwa cha mavuto ndi mbali makina.

Pendani boma la mkati kufunika Borno, fufuzani zikayamba wa akapichi ndi mtedza. Ngati kugwirizana osauka mbali conductive kulephera kwa windings angayambe nthawi iliyonse. Engine pamwamba ayenera kutsukidwa dothi ndi chinyezi mkati kwina.

Ngati ife kuganizira za mmene kutsimikizira galimoto multimeter, m'pofunika kuti tikambirane zina zabwino:

• nkhupakupa Komanso multimeter muyenera kuti contactless kuyeza m'kupita panopa kudzera waya.
• Multimeter akhoza kuyesa kukana kwangochepetsako pang'ono chabe apamwamba. Kuti muone mmene kutchinjiriza (kumene kukana - kuchokera ohms kuti megohms) megoommetr ntchito.
• Kudzatunga mfundo za zotuluka pa galimoto, kuti kusagwirizana zigawo makina (gearbox, mpope, etc.) kapena ayenera onetsetsani Kutukula zonse mwa zigawo izi.

kusintha zipangizo

Kuyamba kumulowetsa kasinthasintha ntchito bolodi kapena kulandirana. Kuyamba kulimbana ndi funso mmene kukayendera galimoto ndi kumulowetsa, m'pofunika disengage unyolo okwanira. Kudzera kungakhale "kulira" zinthu kulamulira gulu kuti alakwitse mu muyeso wa. Pamene ndinu Yohane M'batizi mawaya angathe kuyeza voteji ukubwera kwa otsimikiza mu dera wabwino amagetsi.

Mu zipangizo banja injini kawirikawiri ntchito dongosolo ndi kuyamba kumulowetsa, amene alumphe kulimbikira ntchito ya inductance. Ngati miyezo kuganizira mfundo yakuti kungabweretse panopa yosonkhanitsa burashi. Pa mfundo zokhudzana ndi ozungulira pamaoneka pafupipafupi madipoziti, kuchotsa, muyenera kubwezeretsa malo zoyenera maburashi pa kasinthasintha.

The makina ochapira ntchito Motors ang'ono-kakulidwe ndi athamangadi kumulowetsa. Akamanena lonse matenda yafupika miyezo kukaniza ake. Panopa chimaonekera kamodzikamodzi, koma kukweza makhalidwe imathamanga osiyana zotheka kudzatunga mfundo za Kutukula a galimoto ndi.

Tsatanetsatane matenda magetsi

Taganizirani mmene fufuzani Kutukula a galimoto ndi. Makamaka kuyendera kugwirizana nawo. Ngati iwo alibe kuwonongeka zooneka, kenako malo ndi kugwirizana injini Kulumikizana ndi kusagwirizana iwo. Iwo m'pofunika kudziwa mtundu wa galimoto. Ngati ali wokhometsa, pali slats kapena zigawo mu malo zoyenera maburashi.

Kuti anayeza ndi ohmmeter kukana pakati slats aliyense pafupi. Izo ziyenera kukhala chomwecho milandu onse. Ngati pali gawo yochepa circuited kapena kupuma kwawo, galimoto ayenera m'malo tachosensor. Ngati "prozvanivat" ozungulira koyilo wokha, ndiye mita 12 kungakhale osakwanira. Molondola amapenda boma la kumulowetsa, muyenera kunja kwa thupi mphamvu zoyendetsera. Kungakhale chipika pa PC kapena batire.

Kuyeza yaing'ono kukana makhalidwe mndandanda ndi resistor mpandawo kumulowetsa waikidwa yodziwika mtengo mwadzina. Wokwanira kusankha kukana pafupifupi 20 ohms. Pambuyo magetsi ku mphamvu kunja kuyeza voteji dontho kudutsa kumulowetsa ndi resistor. Chifukwa mtengo kuwapeza chilinganizo R1 = U1 * R2 / U2, kumene R2 - Resistor, U2 - ndi voteji dontho kudutsa izo.

Matenda a Motors asynchronous

Pa mafakitale makina ochapira gwiritsani ntchito zamphamvu Motors atatu gawo. Ozungulira kuti ankachitira mu mawonekedwe a mbale imene pachimake maginito. Gawo windings zambiri atathana ndi anakonza mu stator a. Multimeter kukayendera mota ngati wosalira zambiri. Ohmmeter ayenera alire kukana aliyense kumulowetsa. Izo ziyenera kukhala chomwecho. Musaiwale kukayendera chitsanzo pa thupi ndi kuyeza kukana nyumba ya. Komabe, kutchinjiriza ndi onani Megger.

Mafunso mmene kufufuza galimoto kumulowetsa Tester, tisaiwale kuti "gawo vutoli" mu galimoto asynchronous sikuloledwa. kukana kusiyana sayenera upambana ohm wina. Apo ayi, ukuwonjezeka panopa pa inductance yafupika, imbaenda amaotcha kumulowetsa.

Ngati DC galimoto

injini amenewa kumulowetsa kulimbana ndi otsika kwambiri ndi miyezo ya zimagwiridwa mwa mabomba awiri. Imodzi kuyeza ndi ammeter ndi voltmeter. Monga gwero anasankha batire voteji wa 4-6 V. Mtengo chotsatira ndi chimafotokozera chilinganizo R = U / I.

Chongani windings onse a armature kukana, kuyeza mtengo pakati pa mbale wokhometsa. Chiwerengerochi onse ayenera kukhala wolingana mita. Mwa chitsanzo ichi tikhoza kuganiza kuti aletse galimoto armature.

Kusiyana kukana pakati moyandikana mbale zikuonetsa wokhometsa analola zosaposa 10%. Pamene mawonekedwe chinthu amaperekedwa mu koyilo zokwanira, injini ntchito adzakhala zachilendo pamene kusiyana amayamikira 30%. Multimeter kuwerenga si nthawi zonse kupereka kuneneratu molondola za mmene injini ya makina ochapira. Komanso, injini amafunika kusanthula ntchito pa zitsime calibration.

Poona mwachindunji galimoto galimoto

Ngati ife kuganizira za mmene kukayendera injini ya makina ochapira, m'pofunika kuganizira mtundu wa kugwirizana kwa ng'oma kutsinde. Izo zimatengera mtundu wa kamangidwe ka gawo magetsi. Multimeter prozvanivatsya kumulowetsa, kuzindikira za kukhulupirika kwawo.

Health cheke ikuchitika pambuyo Nyumba sensa m'malo. Zinali iye amene akupita pansi mu nthawi zambiri. Pambuyo kupitiriza kwa windings pamene umphumphu wa ambuye odziwa amalangiza kulumikiza galimoto mwachindunji kwa zopezera 220 V. Chifukwa ndi yunifolomu kasinthasintha kusintha malangizo ake, mukhoza perevotknut pulagi mu kubwereketsa ndi kutembenukira izo anzanu ena.

Njira imeneyi zimathandiza kudziwa vuto wamba. Komabe, pamaso pa kasinthasintha sizitanthauza ntchito bwinobwino m'dzikoli modes onse ena kuposa pa sapota mkombero ndi muzimutsuka.

The ndondomeko ya matenda

Chinthu choyamba Mpofunika yomweyo kulabadira chikhalidwe cha maburashi, Kulumikizana. Nagar mbali moyo limasonyeza zinthu nthenda ya injini. Okha okhometsa ayenera kukhala yosalala, popanda akulimbana ndi zisamayoyoke. Zimakhalapo kuyambitsa arcing, amene chimawononga windings injini.

Mu kusamba makina a ozungulira ndi skewed, chifukwa cha zimenezi imawazidwa kapena slats wosweka. Bolodi kulamulira zonse oyang'anira malo a ozungulira kudzera Hall sensa kapena tachogenerator, kuwonjezera kapena kuchepetsa voteji ntchito kwa koyilo ntchito. Pano pali phokoso pamene limazungulira, sparking chosayenerera pa sapota mkombero.

zodabwitsazi Tingaone kokha pa sapota mkombero ndipo akafuna kusamba umachitika stably. Diagnostics makina sikuti ipyole pa kusanthula mbali magetsi. Zimango kungakhale chifukwa cha wonongeka. Popanda kutsegula injini akhoza sapota ndithu wogawana ndi likunena ikupita patsogolo.

Koma ngati agogoda chitetezo?

Pambuyo miyezo ya anachita vuto akuyandama ali osavomerezeka kugwirizana kwa maukonde kwa yachinsinsi. Mungasonyeze injini pansi kwathunthu sankadziwa vuto. Kodi kufufuza injini kumulowetsa multimeter kuuza mbuye wa pakati utumiki ndi foni. Motsogozedwa wake, kudzakhala kosavuta kudziwa mtundu wa kapangidwe ndi kuyitanitsa matenda wolakwika makina ochapira.

Koma nthawi zambiri, ndi amisiri odziwa sangathe kulimbana ndi kukonza zovuta kumene vuto ndi kuyandama. Kuti muone pamene mukufuna kugwiritsa ntchito makina ochapira ndi ovuta makina zigawo zikuluzikulu. Misalignment ya galimoto kutsinde ndi nkhani yapadera ya mavuto ndi ng'oma kasinthasintha.
