Chikonzero nei jenareta dizeli isingabudisi magetsi

1, Iyo magnetic pole yejenareta inorasikirwa nemagnetism;

2, The excitation circuit element yakakuvadzwa kana mutsetse une break, short circuit kana pasi chiitiko;

3. Iyo exciter bhurashi ine kusabatana kwakashata nekomitator kana bhurashi inobata pressure haina kukwana;

4, Excitation winding wiring error, polarity yakatarisana;

5, ivo jenaretabhurashi uye kutsvedza mhete kubata hakuna kunaka, kana kudzvanywa kwebrashi hakuna kukwana;

6. The stator winding kana rotor winding yejenereta yakaputsika;

7, Jenareta inotungamira mutsara wakasununguka kana switch yekubata haina kunaka;

Diesel jenareta seti isina yazvino uye voltage kubuda kwekugadzirisa nzira

1, multimeter voltage faira yekuona

Shandura iyo multimeter knob ku30V DC voltage (kana shandisa general DC voltmeter yakakodzera faira), batanidza chinyoreso dzvuku kune jenareta "armature" yekubatanidza column, uye batanidza peni nhema kune imba, kuti injini imhanye pamusoro pekumhanya kwepakati. , iyo voltage standard value ye12V yemagetsi system inofanirwa kunge iri 14V, uye voltage standard value ye24V yemagetsi system inofanirwa kunge iri 28V.

2, yekunze ammeter kuona

Kana pasina ammeter pane dashboard yemota, yekunze DC ammeter inogona kushandiswa kuona. Kutanga bvisa jenareta "armature" yekubatanidza waya, uye wozobatanidza danda rakanaka re DC ammeter ine mutsara we 20A kune jenareta "armature", uye iyo yakaipa waya kune iri pamusoro inobvisa connector. Kana injini ichimhanya pamusoro pekumhanya kwepakati (pasina kushandisa mamwe midziyo yemagetsi), ammeter ine 3A-5A yekuchaja chiratidzo kuratidza kutijenaretairi kushanda zvakajairika, kana zvisina kudaro jenareta haigadziri magetsi.

3, mwenje wekuyedza (girobhu remota) nzira

Kana pasina multimeter uye DC mita, magirobhu emotokari anogona kushandiswa sechiedza chekuyedza kuona. Weld waya dzehurefu hwakakodzera kumativi ese egirobhu uye batanidza chinosungirira che alligator kumativi ese. Usati waedza, bvisa kondakita wejenareta "armature" yekubatanidza, wobva wasunga imwe mugumo wechiedza chechiedza kune jenareta "armature" yekubatanidza, uye tora imwe mugumo wesimbi, kana injini iri kushanda nepakati kumhanya, iyo chiedza chekuedza chinoratidza kuti jenareta iri kushanda zvakajairika, kana zvisina kudaro jenareta haizogadziri magetsi.

4, shandura kumhanya kweinjini kuti uone kupenya kwerambi remusoro

Mushure mekutanga injini, batidza mwenje, kuitira kuti injini inomhanya zvishoma nezvishoma iwedzere kubva pakumhanya kusvika kune yepakati kumhanya, kana kupenya kwemwenje kunowedzera nekumhanya, zvinoratidza kuti jenareta inoshanda zvakajairika, zvikasadaro haigadziri. magetsi.

5, multimeter voltage faira kutonga

Rega bhatiri kune jenareta rifare, iyo multimeter yakasarudzwa muDC voltage 3 ~ 5V (kana faira rakakodzera reiyo DC voltmeter) faira, dema uye tsvuku peni yakabatana ne "simbi" uye jenareta "armature" yekubatanidza column. , tenderera bhanhire disk neruoko, iyo multimeter (kana DC voltmeter) pointer inofanira kuzununguka, kana zvisina kudaro jenareta haizogadziri magetsi.
