Fambisa maoko ako madiki uye ugare kure nekutsamwisa kutadza kwemota?
1. Motokari haigoni kutangwa
1. Motokari haitendeuki uye hapana inzwi.Chikonzero ndechekuti kune maviri-chikamu kana matatu-chikamu akavhurika dunhu mumotokari magetsi ekupa kana mhepo.Kutanga tarisa kune magetsi ekupa.Kana pasina magetsi muzvikamu zvitatu, kukanganisa kuri munharaunda;kana matatu-phase voltages akaenzana, kukanganisa kuri mumotokari pachayo.Panguva ino, kupikisa kwematatu-chikamu mamhepo emota anogona kuyerwa kuti awane mahwindi ane chikamu chakavhurika.
2. Motokari haitendeuki, asi kune "humming" inzwi.Pima iyo mota terminal, kana iyo-nhatu-chikamu voltage yakaenzana uye iyo yakayerwa kukosha inogona kutongwa seyakanyanya kuwanda.
Matanho ekuongorora ndeaya: tanga wabvisa mutoro, kana kumhanya uye ruzha rwemotokari zvakajairika, zvinogona kutongwa kuti kuwandisa kana chikamu chemagetsi chemutoro chakashata.Kana iyo isati yatendeuka, unogona kushandura shaft yemota neruoko.Kana yakanyanya kusimba kana isingakwanise kutendeuka, pima matatu-chikamu ikozvino.Kana iyo yechitatu-chikamu ikozvino yakaenzana, asi yakakura kupfuura iyo yakatemerwa kukosha, inogona kunge iri iyo mechanic chikamu chemotor chakamira uye mota Kushaikwa kwemafuta, inotakura ngura kana kukuvadzwa kwakanyanya, chivharo chekupedzisira kana chivharo chemafuta chiri. akaiswa zvakare obliquely, rotor nemukati bhobho zvinobonderana (inonziwo kutsvaira).Kana zvakaoma kushandura shaft yemotokari neruoko kune imwe kona kana kana iwe ukanzwa nguva yenguva "chacha" inzwi, inogona kutongwa sekutsvaira.
Zvikonzero ndezvi:
(1) Mukaha uripo pakati pemhete dzemukati nedzekunze dzebhero wakakurisa, uye chinotakura chinoda kutsiviwa.
(2) Kamuri inotakura (bearing buri) yakakura kwazvo, uye dhayamita yegomba remukati yakakura zvakanyanya nekuda kwekupfeka kwenguva refu.Nhanho yechimbichimbi ndeye electroplate layer yesimbi kana kuwedzera sleeve, kana kubaya tunhu tudiki pamadziro ebhearing chamber.
(3) Shaft yakakotama uye chivharo chekupedzisira chakapfekwa.
3. Motokari inotenderera zvishoma nezvishoma uye inofambidzana ne "humming" inzwi, uye shaft inodedera.Kana iyo yakayerwa ikozvino yeimwe nhanho iri zero, uye ikozvino yezvimwe zvikamu zviviri zvakanyanya kudarika yakayerwa ikozvino, zvinoreva kuti iri maviri-chikamu kushanda.Chikonzero ndechekuti imwe nhanho yedunhu kana simba rekupa rakavhurika kana chimwe chikamu chemotor winding chakavhurika.
Kana imwe nhanho yemota diki yakavhurika, inogona kutariswa ne megohmmeter, multimeter kana mwenje wechikoro.Paunenge uchitarisa mota ine nyeredzi kana delta yekubatanidza, majoini ematatu-chikamu windings anofanirwa kuparadzaniswa, uye chikamu chimwe nechimwe chinofanirwa kuyerwa chedunhu rakavhurika.Mazhinji emagetsi emagetsi epakati-kati anoshandisa waya dzakawanda uye akabatanidzwa mukuenzanisa kumativi akawanda matavi.Zvakanyanya kuoma kutarisa kana waya dzakawanda dzakaputsika kana kuti parallel bazi rakabviswa.Iyo mitatu-chikamu ikozvino kuenzanisa nzira uye nzira yekudzivirira inowanzoshandiswa.Kazhinji, kana musiyano pakati pezvikamu zvitatu zvemazuva ano (kana kuramba) zvakakosha zvinopfuura 5%, chikamu chine chiduku chemazuva ano (kana kupikisa kukuru) ndicho chikamu chedunhu chakazaruka.
Kudzidzira kwakaratidza kuti iyo yakavhurika-yedunhu kukanganisa kwemota inowanzoitika pakupera kwemhepo, kubatana kana kutungamirira.
2. Fuse inofuridzirwa kana thermal relay inodimburwa paunotanga
1. Matanho ekugadzirisa matambudziko.Tarisa kuti fuse inokwana here, kana iri diki, itsive neyakakodzera uye edza zvakare.Kana iyo fuse ikaramba ichivhuvhuta, tarisa kana bhandi rekutyaira rakanyanya kusimba kana mutoro wakakurisa, kana paine pfupi pfupi mudunhu, uye kana iyo mota pachayo ipfupi inotenderera kana yakadzika.
2. Ground kukanganisa kutarisa nzira.Shandisa megohmmeter kuyera kudzivirira kwekudzivirira kwemota inomonereka kusvika pasi.Kana kudzivirira kwekudzivirira kwakadzikira kupfuura 0.2MΩ, zvinoreva kuti mhepo yakanyorova yakanyorova uye inofanira kuomeswa.Kana kupikisa kuri zero kana kuti calibration rambi iri pedyo nekupenya kwakajairika, chikamu chinodzika.Winding grounding inowanzoitika pakubuda kwemota, gomba rekupinza retambo yemagetsi kana mhepo yekuwedzera slot.Nokuda kwechiitiko chekupedzisira, kana zvikaonekwa kuti kukanganisa kwepasi hakusi kwakakomba, bamboo kana pepa rekudzivirira rinogona kuiswa pakati pe stator core uye mhepo.Mushure mekusimbisa kuti hapana chigadziko, chinogona kuputirwa, kupendwa nependi inodzivirira uye yakaomeswa, uye inoramba ichishandiswa mushure mekupfuura kuongorora.
3. Nzira yekuongorora yekumonera kukanganisa kwepfupi-dunhu.Shandisa megohmmeter kana multimeter kuyera kudzivirira kwekudzivirira pakati pezvikamu zviviri pamitsetse yekubatanidza.Kana iri padhuze ne zero pazasi 0.2Mf, zvinoreva kuti ipfupi dunhu pakati pezvikamu.Kuyera mafungu emagetsi matatu zvakateerana, nhanho ine yakakura ikozvino ipfupi-yedunhu chikamu, uye pfupi-yedunhu detector inogona zvakare kushandiswa kutarisa interphase uye inter-turn mapfupi maseketi emhepo.
4. Kutonga nzira ye stator inotenderera musoro nemuswe.Paunenge uchigadzirisa uye uchitarisa mota, zvinodikanwa kuti uongorore zvakare musoro uye muswe weiyo stator winding yemota kana iyo yekubuda ichibviswa uye kukanganwa kunyorwa kana iyo yekutanga label yakarasika.Kazhinji, iyo yekucheka yakasara magineti yekuongorora nzira, iyo induction yekuongorora nzira, iyo diode yekuratidza nzira uye yakananga nzira yekusimbisa yemutsara wekuchinja inogona kushandiswa.Nzira dzekutanga dzakati wandei dzese dzinoda zvimwe zviridzwa, uye muyeri anofanira kunge aine ruzivo runoshanda.Iyo yakananga yekusimbisa mutemo wekushandura musoro weshinda iri nyore, uye yakachengeteka, yakavimbika uye intuitive.Shandisa iyo ohm block ye multimeter kuyera kuti ndeapi waya anogumira chikamu chimwe, uye nekupokana maka musoro nemuswe we stator winding.Misoro mitatu (kana miswe mitatu) yenhamba dzakatarwa yakabatana nedunhu zvakateerana, uye miswe mitatu yasara (kana misoro mitatu) yakabatana pamwechete.Tanga injini isina mutoro.Kana kutanga kunonoka uye ruzha rwakanyanya, zvinoreva kuti musoro nemuswe wechimwe chikamu chekutenderera zvinodzoserwa kumashure.Panguva ino, simba rinofanira kubviswa pakarepo, nzvimbo yekubatanidza yeimwe yezvikamu inofanira kuchinjwa, uye ipapo simba rinofanira kuvhurwa.Kana ichiri yakafanana, zvinoreva kuti chikamu chekuchinja hachina kudzoserwa.Dzorera musoro nemuswe wechikamu ichi, uye shandura zvimwe zvikamu zviviri nenzira imwechete kusvikira ruzha rwekutanga rwemotokari rwakajairika.Iyi nzira iri nyore, asi inofanirwa kungoshandiswa padiki nepakati mota dzinobvumira kutanga kwakananga.Iyi nzira haigone kushandiswa kune mota dzine huwandu hukuru husingabvumiri kutanga kwakananga.
