Injini ndiyofunikira kwambiri komanso yopatsa mphamvu pakupanga ndi moyo wa anthu.Ma motors ambiri amatulutsa kutentha kwakukulu pakagwiritsidwa ntchito, koma nthawi zambiri sadziwa momwe angawathetsere.Chachikulu ndichakuti sadziwa chifukwa chake.Kutentha kotsatira kwa injini kuyenera kukhala koyambirira kugwiridwa pakugwiritsa ntchito mota.Tiyeni tiwone zifukwa zomwe zimachititsa kuti injini ikhale yotentha kwambiri.

1. Kusiyana kwa mpweya pakati pa stator ndi rotor ya injini ndi yaying'ono kwambiri, yomwe ingayambitse kugunda pakati pa stator ndi rotor.

Mu ma motors apakati ndi ang'onoang'ono, kusiyana kwa mpweya nthawi zambiri kumakhala 0.2mm mpaka 1.5mm.Pamene kusiyana kwa mpweya kuli kwakukulu, mphamvu yokoka imayenera kukhala yaikulu, potero imakhudza mphamvu ya galimoto;ngati kusiyana kwa mpweya kuli kochepa kwambiri, rotor ikhoza kupukuta kapena kugunda.Nthawi zambiri, chifukwa cha kulekerera kwakukulu kwa kunyamula komanso kuwonongeka ndi kupindika kwa dzenje lamkati la chivundikiro chomaliza, nkhwangwa zosiyanasiyana zamakina, chivundikiro chakumapeto ndi rotor zingayambitse kusesa, zomwe zingayambitse injini kuti itenthe kapena kuyaka.Ngati kubereka kwapezeka kuti kwavala, kuyenera kusinthidwa pakapita nthawi, ndipo chivundikiro chomaliza chiyenera kusinthidwa kapena kutsukidwa.Njira yosavuta yochizira ndikuyika chivundikiro chomaliza.

2. Kugwedezeka kosazolowereka kapena phokoso la mota kungapangitse injini kutenthedwa mosavuta

Izi ndizomwe zimachitika chifukwa cha kugwedezeka komwe kumachitika chifukwa cha injini yomwe, zambiri zomwe zimachitika chifukwa cha kusayenda bwino kwa rotor, kusayenda bwino, shaft yopindika, malo osiyanasiyana otsekera kumapeto, makina oyambira, ndi rotor, zomangira zotayirira, kapena zosagwirizana. maziko a kuyika kwa galimoto, ndi kuyika kosayenera Zingayambitsidwe ndi kufalitsa kuchokera kumapeto kwa makina, zomwe ziyenera kuchotsedwa malinga ndi momwe zilili.

3. Ngati kubereka sikukugwira ntchito bwino, ndithudi kudzachititsa kuti galimotoyo itenthe.Kaya kunyamula kumagwira ntchito moyenera kungayesedwe ndikumva komanso kutentha.

Mutha kuyang'ana kumapeto kwake ndi manja anu kapena thermometer kuti muwone ngati kutentha kwake kuli mkati mwanthawi zonse;mutha kugwiritsanso ntchito ndodo yomvetsera (ndodo yamkuwa) kuti mugwire bokosi lonyamulira.Ngati mumva phokoso lakugunda, zikutanthauza kuti mpira umodzi kapena angapo ukhoza kuphwanyidwa.Phokoso loyimba, zikutanthauza kuti mafuta opangira mafuta sakwanira, ndipo injini iyenera kusintha mafuta opaka maola 3,000 aliwonse mpaka maola 5,000.

4. Mphamvu yamagetsi yamagetsi ndiyokwera kwambiri, mphamvu yamagetsi ikuwonjezeka, ndipo galimoto idzatentha kwambiri

Kuchuluka kwamagetsi kumatha kusokoneza kutsekemera kwa mota, ndikuyika pachiwopsezo cha kuwonongeka.Mphamvu yamagetsi ikatsika kwambiri, torque yamagetsi imachepa.Ngati torque yolemetsa sichepa ndipo liwiro la rotor ndilotsika kwambiri, kutsetsereka kowonjezereka kumapangitsa kuti mota ichulukitsidwe ndikuwotcha.Kuchulukira kwanthawi yayitali kumakhudza moyo wagalimoto.Pamene voteji ya magawo atatu ndi asymmetrical, ndiye kuti, pamene magetsi a gawo limodzi ali okwera kapena otsika, mphamvu ya gawo linalake idzakhala yaikulu kwambiri, ndipo galimotoyo idzawotcha.Panthawi imodzimodziyo, torque idzachepa ndipo phokoso la "kung'ung'udza" lidzatulutsidwa.Pakapita nthawi yayitali, chimphepocho chidzawonongeka.

Mwachidule, ziribe kanthu kaya magetsi ndi okwera kwambiri, otsika kwambiri kapena magetsi ndi asymmetrical, zamakono zidzawonjezeka, ndipo galimotoyo idzawotcha ndikuwononga galimotoyo.Chifukwa chake, malinga ndi muyezo wadziko lonse, kusintha kwamagetsi amagetsi agalimoto sikuyenera kupitilira ± 5% ya mtengo wake, ndipo mphamvu yotulutsa yamoto imatha kusunga mtengo wake.Mphamvu yamagetsi yamagetsi sikuloledwa kupitirira ± 10% ya mtengo wake, ndipo kusiyana pakati pa magawo atatu amagetsi amagetsi sikuyenera kupitirira ± 5% ya mtengo wake.

5. Mayendedwe afupikitsa, kutembenuka-kutembenukira-kuzungulira dera lalifupi, gawo-to-gawo lalifupi lozungulira komanso lotseguka lotseguka

Pambuyo pa kutchinjiriza pakati pa mawaya awiri oyandikana nawo pakuwonongeka, ma conductor awiriwa amakhudzana wina ndi mnzake, womwe umatchedwa kuti mawilo afupikitsa.Mayendedwe afupikitsa omwe amapezeka mumayendedwe omwewo amatchedwa mabwalo afupikitsa.Dongosolo lalifupi lozungulira lomwe limapezeka pakati pa magawo awiri ozungulira limatchedwa gawo-to-phase short circuit.Ziribe kanthu kuti ndi iti, imachulukitsa kuchuluka kwa gawo limodzi kapena magawo awiri, kuchititsa kutentha kwanuko, ndikukulitsa kutsekereza kuwononga injini.Mayendedwe otseguka amatanthauza kulephera komwe kumachitika chifukwa cha mafunde a stator kapena rotor ya mota yomwe ikusweka kapena kuwomberedwa.Kaya ndi kagawo kakang'ono kapena kotseguka kozungulira, kungayambitse injini kutentha kapena kuwotcha.Choncho, iyenera kutsekedwa mwamsanga izi zikachitika.

6. Zinthuzo zimalowa m'galimoto, zomwe zimachepetsa kutsekemera kwa injini, motero kuchepetsa kutentha kovomerezeka kwa galimotoyo.

Ngati zinthu zolimba kapena fumbi lilowa mugalimoto kuchokera mubokosi lolumikizirana, limafikira kusiyana kwa mpweya pakati pa stator ndi rotor ya mota, zomwe zimapangitsa kuti injiniyo isasese, mpaka kutsekeka kwa mafunde agalimoto kutha, ndipo galimotoyo iwonongeka. kapena kuchotsedwa.Ngati media yamadzi ndi mpweya itsikira mu mota, ipangitsa kuti kutsekeka kwa injini kugwere ndikuyendayenda.Kutayikira kwamadzi ndi gasi kumakhala ndi izi:

(1) Kutayikira kwa muli zosiyanasiyana ndi mapaipi yobereka, kutayikira kwa mpope zisindikizo thupi, flushing zida ndi pansi, etc.

(2) Mafuta akamawotchera, amalowa m'galimoto kuchokera pachipata cha bokosi lakutsogolo.

(3) Chisindikizo chamafuta cha chochepetsera cholumikizidwa ndi mota chimang'ambika, ndipo mafuta opaka makina amalowa motsatira shaft yamoto.Pambuyo pakuwunjikana mkati mwa mota, imasungunula varnish ya motor insulation, yomwe imachepetsa pang'onopang'ono magwiridwe antchito a mota.

7. Pafupifupi theka la mawotchi oyaka moto amayamba chifukwa cha kusowa kwa gawo la galimotoyo

Kuperewera kwa gawo nthawi zambiri kumapangitsa kuti galimotoyo isathe kuthamanga kapena kuthamanga kumachedwa pambuyo poyambira, kapena pamakhala phokoso la "kung'ung'udza" pamene kusinthasintha kuli kofooka ndipo panopa akuwonjezeka.Ngati katundu pa shaft sasintha, galimotoyo imakhala yodzaza kwambiri, ndipo stator yamakono idzafika ku 2 kuwirikiza mtengo wake kapena kupitilira apo.Galimoto imatha kutentha kapena kupsa pakapita nthawi.Zifukwa zazikulu za kusowa kwa gawo la ntchito ndi izi:

(1) Ngati gawo limodzi la chingwe chamagetsi likudulidwa chifukwa cha kulephera kwa zipangizo zina, zida zina zamagulu atatu zomwe zimagwirizanitsidwa ndi chingwecho zidzathamanga popanda gawo.

(2) Gawo limodzi la ophwanya dera kapena contactor yatha chifukwa cha kukondera voteji kuwotcha kapena kukhudzana osauka.

(3) Kusowa kwa gawo chifukwa cha ukalamba ndi kuvala kwa mzere wolowera wagalimoto.

(4) Mapiritsi a gawo limodzi lagalimoto lathyoka, kapena cholumikizira cha gawo limodzi mubokosi lolumikizana ndi lotayirira.

8. Zina zosagwirizana ndi makina ndi magetsi zimayambitsa

Kuwonjezeka kwa kutentha kwa galimoto chifukwa cha zolakwika zina zomwe si za makina ndi magetsi kungayambitsenso kulephera kwa magalimoto pazovuta kwambiri.Ngati kutentha kwazungulira kuli kwakukulu, injini ilibe fani, chowotcha chimakhala chosakwanira, kapena chivundikiro cha fani chikusowa.Pankhaniyi, ndikofunikira kukakamiza kuziziritsa kuti mutsimikizire mpweya wabwino kapena kusintha masamba a fan, apo ayi ntchito yabwinobwino yagalimoto singakhale yotsimikizika.

Pomaliza, kuti mugwiritse ntchito njira yolondola yothanirana ndi zolakwika zamagalimoto, ndikofunikira kudziwa bwino mawonekedwe ndi zomwe zimayambitsa zolakwika zamagalimoto wamba, kumvetsetsa zinthu zofunika kwambiri, ndikuwunika ndikuwongolera pafupipafupi.Mwanjira iyi, zopotoka zimatha kupewedwa, nthawi imatha kupulumutsidwa, zolakwika zitha kuthetsedwa posachedwa, ndipo mota ikhoza kukhala yogwira ntchito bwino.Pofuna kuonetsetsa kuti msonkhanowo ukuyenda bwino.
