Malo apadera ali ndi zofunikira zapadera zotetezera kutentha ndi kutetezamotaChifukwa chake, pomaliza mgwirizano wa injini, malo ogwiritsira ntchito injini ayenera kutsimikiziridwa ndi kasitomala kuti apewe kulephera kwa injini chifukwa cha mikhalidwe yosayenera yogwirira ntchito.
Njira zotetezera kutentha kwa ma mota oletsa dzimbiri a mankhwala Ma mota oletsa dzimbiri a mankhwala, kaya ayikidwa m'nyumba kapena panja, ayenera kukhala ndi mphamvu zoteteza chinyezi komanso zoteteza dzimbiri. Zipangizo zamakono zamafakitale a mankhwala ndi zida zimakhala zazikulu komanso zotseguka. Kupanga kosalekeza kumatanthauza kuti zida zikayamba kugwira ntchito, nthawi zambiri sizingatsekedwe kuti zikonzedwe kwa nthawi yayitali. Chifukwa chake, ma mota omwe amagwiritsidwa ntchito m'mafakitale a mankhwala ali ndi zofunikira zotetezera kwambiri ndipo ayenera kutengera mtundu wakunja. Kuti awonjezere mphamvu zoteteza dzimbiri, kapangidwe ka kapangidwe kake kayenera kulimbitsa kutseka kwa chipolopolocho. Pamene malo otulutsira madzi ayenera kusungidwa mu chipolopolocho, ayenera kutsekedwa ndi zomangira zapulasitiki. Njira yayikulu yopumira ya injini yotsekedwa ndi bearing. Kapangidwe kotseka ndi chivundikiro chosalowa madzi ndi mphete yokhotakhota kangathandize kwambiri kuteteza. Ma bearing a ma mota akuluakulu ayenera kupangidwa kuti awonjezere mafuta ndikusintha mafuta popanda kuyima, kuti akhale oyenera kupanga mosalekeza m'mafakitale a mankhwala. Amafuna. Zigawo zowonekera ziyenera kupangidwa ndi chitsulo chosapanga dzimbiri ndi pulasitiki.
Pansi pa chitetezo cha chivundikiro chotsekedwa, njira zotetezera kutentha kwa ma mota a mankhwala oletsa dzimbiri zitha kuchitidwa mofanana ndi ma mota a m'madera otentha. Ma mota amphamvu kwambiri amatha kutetezedwa ndi epoxy powder mica tape continuous insulation yodzazidwa ndi utoto wonse kapena silicone rabara insulation. Njira zotetezera kutentha kwa ma mota akunja Chitetezo cha ma mota akunja makamaka ndi chitetezo cha kapangidwe kake kuti apewe kulowerera kwa nyama zazing'ono ndi mvula, chipale chofewa, mphepo ndi mchenga. Mlingo wotsekereza chipolopolocho umadalira momwe chipolopolocho chimagwirira ntchito ndi waya wotulutsira. Gawo lothandizira la mota wakunja liyenera kukhala ndi mphete yolumikizira madzi. Malo olumikizirana pakati pa bokosi lolumikizira ndi maziko a makina ayenera kukhala otakata komanso athyathyathya. Gasket yotsekereza iyenera kuyikidwa pakati. Mzere wolowera uyenera kukhala ndi chigoba chotsekereza. Msoko wa chivundikiro chakumapeto ndi dzenje lokweza maso liyenera kukhala ndi ma gasket a rabara. Zomangira zomangira ziyenera kugwiritsa ntchito zomangira mutu wozungulira ndi zotsukira zotsukira. Mpweya wopumira wa galimoto yakunja uyenera kukhala ndi kapangidwe koletsa mphepo, chipale chofewa kapena zinthu zakunja kuti zisalowe. Mutha kugwiritsa ntchito ma ducts opumira kapena kukhazikitsa ma baffles mu duct ya mpweya kuti mulekanitse mvula, chipale chofewa ndi mchenga. Zosefera za fumbi zitha kuwonjezeredwa m'malo okhala fumbi.
Kuwonjezera pa kusankha zipangizo zoyenera zotetezera kutentha, gwiritsani ntchito njira zoyenera zotetezera kutentha kuti mupange gawo lokwanira loteteza pamwamba pa kutentha. Kuti muteteze ku kuwala kwa dzuwa, chophimba cha dzuwa chikhoza kuyikidwa pamwamba pa chipolopolo. Payenera kukhala mtunda wina pakati pa chophimba cha dzuwa ndi chipolopolo kuti mupewe kukhudzana mwachindunji ndi chipolopolocho. M'zaka zaposachedwapa, mabokosi ozizira nthawi zambiri amaikidwa pa stator. Pofuna kupewa kuzizira pa mota, chotenthetsera chosanyowa chikhoza kuyikidwa.
Ma mota akunja amatha kutetezedwa mofanana ndi ma mota otentha. Kupanga zinthu zatsopano zotetezera kutentha ndi njira zatsopano zotetezera kutentha m'zaka zaposachedwa kumatha kutseka bwino magawo a ma mota popanda kutseka mota yonse. Mayiko ambiri amagwiritsa ntchito mtundu woteteza m'malo mwa mtundu wotsekedwa kwathunthu. Ma mota akunja otetezedwa amatha kugwiritsa ntchito ma sealed windings. Izi zikutanthauza kuti, ma windings amapangidwa ndi zinthu zotetezera kutentha zomwe sizili ndi hygroscopic ndi mawaya amagetsi. Pambuyo poti stator winding yalowetsedwa, njira yonse yotetezera kutentha imagwiritsidwa ntchito. Ma windings ndi ma connections onse amatsekedwa, zomwe zimatha kupewa kuipitsa mpweya ndikusinthasintha kuti zigwirizane ndi nyengo yakunja. Ma mota akunja ayenera kugwiritsa ntchito utoto wa pamwamba wokhala ndi mphamvu yoletsa kuwala. Woyera uli ndi zotsatira zabwino kwambiri, kutsatiridwa ndi woyera wasiliva. Chisamaliro chapadera chiyenera kuperekedwa pa magwiridwe antchito a kuwala kwa mapulasitiki omwe amagwiritsidwa ntchito panja. Pa kutentha kochepa, mapulasitiki ndi mafuta nthawi zambiri amakhala ofooka kapena olimba, kotero zinthu zomwe zimakhala ndi mphamvu yolimbana ndi kuzizira ziyenera kugwiritsidwa ntchito.
