Zvikonzero zvekupisa mota

Zvikonzero zvekupisa mota zvinogona kukamurwa kuita: mutoro, magetsi ekupa, mota insulation,default phase

1.Default chikamu

Chikonzero:Kazhinji nekuda kwekushaikwa kwesimba rechikamu.(1 chikamu chisina kupihwa kana kusakwana kwemagetsi voltage).Kana contactor yekubata point mumutsara haina kuvharwa.The wire connection point inodimbura, kusunungura kana kubata chinzvimbo oxidizes zvikonzero uye zvichingodaro.

Hunhu:Chikamu chimwe kana zviviri (chikamu che4) mumhepo zvinoputika zvose zvakasvibiswa, iyo coil yakakuvadzwa symmetrically.

2.Overload

Chikonzero:Kazhinji inguva yakareba yekumhanya pamusoro pezvino, kupisa, kazhinji kutanga kana kubhureki,wiring kukanganisa.

Hunhu:Kupeta kwese kunobva kwaita dema, chinosunga kumagumo chinoshanduka uye chinova brittle kana kutotyoka.

3.Interturn

Chikonzero:Enameled waya inoputika kubva mukugadzira mota, uye mvura, asidhi, uye zvimwe zvinhu zvinoparadza zviri muhurongwa zvinogona kukonzera kutadza kwakadaro.

Hunhu:Iyo inomonereka inopiswa zvishoma, kazhinji mota mhango yakachena, pane imwe chete nzvimbo inoputika.

4.Electrode maviri-chikamu

Chikonzero:Iyo interphase bepa haisi munzvimbo, kana iyo interphase bepa (casing) yakaputswa.

Hunhu:Iyo mota inodzima pakati pezvikamu zviviri.

5.Stroke

Chikonzero:Chinhambwe chisina kukwana pakati pecoil neend cover cover.

Hunhu:Pane mavanga ekutsva kumativi ese ari maviri pakati pekoiri nekavha yekupedzisira.

Nzira yekudzivirira sei injini kubva pakupisa?

1.Chengeta injini yakachena

Iyo mota inofanirwa kugara ichichengeta mhepo inopinza yakachena panguva yekushanda.

Kana guruva, mafuta uye mvura zvakakweverwa mumotokari, pfupi pfupi yepakati inoumbwa kuti ikuvadze kuvharwa kwewaya.

Zvinokonzeresa kutenderedza pfupi dunhu, iyo ikozvino inowedzera, tembiricha inokwira, inopisa mota.

2.Shanda pasi pemutoro wakatemerwa

Mota yakawandisa mashandiro, chikonzero chikuru ndechekuti mutoro wekudhonza wakakurisa, voltage yakaderera, kana muchina unotyairwa wakanamatira.

Kana mota ichifamba munzvimbo yekuremerwa, kumhanya kwemota kunoderera, ikozvino kunowedzera, tembiricha inowedzera uye coil inopisa.Kana mota yakaremerwa kwenguva yakareba, inopera pasi pekutadza kwekuchembera kwekudzivirira pakupisa kwakanyanya. , ndicho chikonzero chikuru chekuti injini inopisa.

3.Chengetedza nhatu-chikamu ikozvino yakasimba

Kune matatu-chikamu asynchronous motors, mutsauko uripo pakati peavhareji kukosha kwechero chikamu chimwe chete chazvino uye icho chechimwe chikamu chechipiri chazvino hachibvumirwe kudarika 10% kuitira kuvimbisa kushanda kwakachengeteka uye kwakajairwa kwemota.

Kana chiyero chepakati che-single-phase current uye chiyero chepakati chezvimwe zvikamu zviviri zvezvino zvinodarika muganhu wakatemwa, zvinoratidza kuti motokari ine chikanganiso.Chikonzero chacho chinofanira kuwanikwa uye kukanganisa kunogona kubviswa motokari isati yaramba ichishanda, kana zvisina kudaro motokari ichapiswa.

4.Chengetedza tembiricha yakajairika

Tembiricha yekubereka, stator, yakavharirwa uye zvimwe zvikamu zvemota zvinotariswa kazhinji kune anomalies, kunyanya kune mota isina voltage, ikozvino uye frequency yekutarisa zvivakwa uye zvivakwa zvekudzivirira zvakawandirwa, uye tembiricha yekukwira kwekutarisa kwakakosha.

Kana kutonhora kuchikwira pedyo nekutakura kunowanikwa kwakanyanyisa, kunofanira kumira pakarepo kutarisa kana kutakura kwakakanganiswa kana kupfupika kwemafuta.Kana mabhengi ari mashoma emafuta, girizi inofanira kuwedzerwa;kana zvikasadaro, mabearings achawedzera kukuvadzwa, zvichikonzera kudonha, izvo zvichaparadza mota nekutsvaira.

5.Chengetedza kuzunguzika, ruzha, uye hwema

Kana iyo mota ikazununguka, inokonzeresa iyo isiri-coaxiality yemota yakabatana nayo kuti iwedzere, izvo zvinowedzera mutoro wemota, kuwedzera ikozvino, uye kuwedzera tembiricha uye kupisa mota.

Naizvozvo, kana mota ichimhanya, zvinodikanwa kuti utarise nguva nenguva kana mabhaudhi anchor, chivharo chekupedzisira chemota uye chivharo chekumanikidza chekutakura chakasununguka, uye kana mudziyo wekubatanidza wakavimbika.Kana chero dambudziko rawanikwa, rinofanira kugadziriswa nenguva.

6.Ita shuwa kushanda kwakajairika kwemidziyo yekutanga

Kuchengetedza kukuru kwekutanga ndiko kuchenesa uye kusungirira.Kana kusangana kwekubatana kusina kuchena, kupikisa kwekubatana kuchawedzerwa, zvichiita kuti kupisa kwekubatana, kunokonzera kushayikwa kwechikamu uye kupisa kwemotokari. kuunganidzwa kwepakati pemagineti coil yecontact kuchaita kuti coil isavhare zvakasimba uye ichipa kunze ruzha rwakasimba, kuwedzera coil ikozvino, kupisa coil uye kukonzera kukanganisa.

Midziyo yekudzora yemagetsi inofanirwa kunge yakaoma, inofefetera uye iri nyore kushanda chinzvimbo.Bvisa guruva nguva nenguva, simbisa ese ma screws, tarisa kana kubata kwe contactor kwakanaka uye kwakavimbika, uye kana ma mechanical parts ari sensitive uye akarurama.Chengetedza mota in good technical condition. , kuitira kuti injini inogona kutanga zvakanaka pasina kupisa.
