1.Ntchito yoviika utoto

1. Kupititsa patsogolo ntchito yoteteza chinyezi ya ma motor windings.

Pamapeto pake, pali ma pores ambiri muzitsulo zotsekemera, kutsekemera kwa interlayer, kutsekemera kwa gawo, mawaya omangirira, etc.N'zosavuta kuyamwa chinyezi mumlengalenga ndikuchepetsa ntchito yake yotsekemera. Pambuyo pa kuviika ndi kuumitsa, galimotoyo imadzazidwa ndi utoto wotsekereza ndipo imapanga filimu yosalala yosalala, yomwe imapangitsa kuti zikhale zovuta kuti chinyontho ndi mpweya wowononga zilowerere, potero kumapangitsa kuti mafunde amadzimadzi asawonongeke komanso kuti asawonongeke.

2.Kupititsa patsogolo mphamvu yamagetsi yamagetsi yamagetsi.

Pambuyo pa ma windings amizidwa mu utoto ndi zouma, kutembenuka kwawo, ma coils, magawo ndi zipangizo zosiyanasiyana zotetezera zimadzazidwa ndi utoto wotsekemera wokhala ndi zinthu zabwino za dielectric, zomwe zimapangitsa kuti mphamvu yazitsulo ikhale yokwera kwambiri kuposa isanayambe kuyika mu utoto.

3.Kupititsa patsogolo kutentha kwa kutentha ndi kupititsa patsogolo kutentha kwa kutentha.

Kutentha kwa injini pakugwira ntchito kwa nthawi yayitali kumakhudza mwachindunji moyo wake wautumiki. Kutentha kwa mafunde kumasamutsidwa ku sinki ya kutentha kudzera muzitsulo zotsekemera. Mipata ikuluikulu pakati pa mapepala otchinjiriza waya musanayambe kupukuta sikoyenera kuyendetsa kutentha pakumangirira. Pambuyo pakupukuta ndi kuyanika, mipata iyi imadzazidwa ndi varnish yoteteza. The matenthedwe conductivity wa insulating varnish ndi bwino kwambiri kuposa mpweya, motero kumapangitsa kwambiri kutentha dissipation mikhalidwe yokhotakhota.

2. Mitundu ya varnish yoteteza

Pali mitundu yambiri ya insulating penti，Monga epoxy poliyesitala, polyurethane, ndi polyimide.Kawirikawiri, lolingana insulating utoto amasankhidwa malinga ndi mlingo kutentha kukana, monga 162 epoxy ester wofiira enamel kalasi B (130 madigiri) 9129 epoxy zosungunulira-free topcoat F (155 digiri silikoni puréester), 1970 polyesterified polyester 1970, polyester 1970, polyester; momwe utoto wotsekera umakumana ndi zomwe zimafunikira kukana kutentha, uyenera kusankhidwa molingana ndi malo omwe galimotoyo ili, monga matenthedwe amafuta, kukana chinyezi, ndi zina zambiri.

3. Mitundu isanu ya njira zopangira varnish

1.Kuthira

Pokonza injini imodzi, varnish yokhotakhota imatha kutsanuliridwa ndi kuthira. Mukathira, ikani stator molunjika pa thireyi yopopera utoto ndi mapeto amodzi a mafunde akuyang'ana mmwamba, ndipo gwiritsani ntchito mphika wa penti kapena burashi ya penti kutsanulira utoto kumapeto kwa kumtunda kwa mphepo. watsanulidwa kwathunthu.

2.Drip leaching

Njirayi ndiyoyenera kupukuta ma mota amagetsi ang'onoang'ono komanso apakatikati.

①Fomula. 6101 epoxy resin (chiŵerengero cha misa), 50% tung mafuta maleic anhydride, okonzeka kugwiritsidwa ntchito.

②Kutentha Kwambiri: Kutenthetsa mafunde kwa mphindi pafupifupi 4, ndikuwongolera kutentha kwapakati pa 100 ndi 115 ° C (kuyezedwa ndi thermometer ya malo), kapena ikani chimphepocho mu ng'anjo yowumitsa ndikutenthetsa kwa maola pafupifupi 0.5.

③Kudontha. Ikani stator ya injini molunjika pa thireyi ya penti, ndikuyamba kudontha utoto pamanja pamene kutentha kwa injini kutsika mpaka 60-70 ℃. Pambuyo pa mphindi 10, tembenuzirani stator ndikudontha utoto kumbali ina ya mapiringidzo mpaka itanyowetsedwa bwino.

④Kuchiritsa. Pambuyo pakudontha, mafunde amapatsidwa mphamvu zochiritsira, ndipo kutentha kwa mphepo kumasungidwa pa 100-150 ° C; kukana mtengo wa kutchinjiriza amayezedwa mpaka woyenerera (20MΩ), kapena mapiringidzo amaikidwa mu ng'anjo kuyanika kutentha pa kutentha komweko kwa pafupifupi 2 hours (malingana ndi kukula kwa galimoto), ndipo amachotsedwa mu uvuni pamene kutchinjiriza kukana kuposa 1.5MΩ.

3.Utoto wodzigudubuza

Njirayi ndi yoyenera kupukuta kwa ma motors apakati. Mukapukuta utoto, tsitsani utoto wotsekera mu thanki ya penti, ikani rotor mu thanki ya utoto, ndipo pentiyo iyenera kumizidwa mozungulira kuzungulira kwa 200mm. Ngati thanki ya penti ndi yozama kwambiri ndipo malo ozungulira ozungulira omizidwa mu utoto ndi ochepa, rotor iyenera kukulungidwa kangapo, kapena utoto uyenera kupakidwa ndi burashi pomwe rotor ikugubuduzika. Nthawi zambiri kugudubuza ka 3 mpaka 5 kumatha kupangitsa kuti utoto wotsekera ulowe mkati mwazotsekera.

4.Kumiza

Pokonza ma motors ang'onoang'ono ndi apakatikati mumagulu, ma windings amatha kumizidwa mu utoto. Mukamiza, choyamba ikani utoto wokwanira wa insulating mu utoto, kenaka mupachike stator yamoto, kuti madzi a utoto amize stator ndi kupitirira 200mm. Pamene utoto wamadzimadzi umalowa m'mipata yonse pakati pa ma windings ndi mapepala otetezera, stator imakwezedwa mmwamba ndipo utoto umadonthetsedwa. Ngati kuthamanga kwa 0.3 ~ 0.5MPa kumawonjezeredwa panthawi yomiza, zotsatira zake zidzakhala bwino.

5.Vacuum kuthamanga kumizidwa

Ma windings a ma motors okwera kwambiri komanso ma motors ang'onoang'ono ndi apakatikati okhala ndi zofunikira zamtundu wapamwamba kwambiri amatha kukhala ndi vacuum pressure dipping. Pakuviika, stator ya mota imayikidwa mu chidebe chotsekedwa cha utoto ndipo chinyezi chimachotsedwa pogwiritsa ntchito ukadaulo wa vacuum. Pambuyo pa ma windings amizidwa mu utoto, kukakamiza kwa 200 mpaka 700 kPa kumagwiritsidwa ntchito pamwamba pa utoto kuti madzi a penti alowe m'mipata yonse ya ma windings ndi kulowa mkati mwa ma pores a pepala lotetezera kuti atsimikizire ubwino wa kuviika.
