Njira yogwirira ntchito ya mota kwenikweni ndi njira yosinthira mphamvu zamagetsi ndi mphamvu zamakanika, ndipo kutayika kwina kudzachitika mosalephera panthawiyi. Zambiri mwa kutayika kumeneku zimasinthidwa kukhala kutentha, zomwe zimawonjezera kutentha kwa ma windings a mota, chitsulo, ndi zigawo zina.
Mavuto otenthetsera injini ndi ofala kwambiri mu kafukufuku ndi chitukuko komanso kupanga zinthu zatsopano. Mayi Shen akumananso ndi zochitika zambiri pomwe kutentha kwa injini kumakwera pang'onopang'ono ndipo zimakhala zovuta kukhazikika kutentha komwe kumakwera panthawi yoyesa mtundu. Kuphatikiza ndi funso ili, Mayi Shen adachita nawo mwachidule lero kuti akambirane za njira yozizira ndi mpweya wabwino komanso kuyeretsa kutentha kwa injini, kusanthula kapangidwe ka mpweya wabwino ndi kuziziritsa kwa injini zosiyanasiyana, ndikuyesera kupeza njira zina zopangira kuti injini isatenthe kwambiri.
Popeza zinthu zotetezera kutentha zomwe zimagwiritsidwa ntchito mu mota zili ndi malire a kutentha, ntchito yoziziritsa mota ndikuchotsa kutentha komwe kumachitika chifukwa cha kutayika kwa mkati mwa mota, kuti kutentha kwa gawo lililonse la mota kusungidwe mkati mwa mulingo womwe wafotokozedwa ndi muyezo, ndipo kutentha kwamkati kuyenera kukhala kofanana.
Mota nthawi zambiri imagwiritsa ntchito mpweya kapena madzi ngati njira yoziziritsira, ndipo zodziwika bwino ndi mpweya ndi madzi, zomwe timazitcha kuti kuziziritsa mpweya kapena kuziziritsa madzi. Kuziziritsa mpweya nthawi zambiri kumagwiritsidwa ntchito poziziritsa mpweya wotsekedwa bwino komanso kuziziritsa mpweya wotseguka; kuziziritsa madzi nthawi zambiri kumachitika poziziritsa madzi ndi chotenthetsera kutentha.
Muyezo wa injini ya AC IEC60034-6 umalongosola ndi kufotokoza njira yozizira ya injiniyo, yomwe imayimiridwa ndi code ya IC:
Khodi ya njira yozizira = khodi ya IC+ yokonzera dera + khodi yapakati yozizira + khodi ya njira yokankhira
1. Njira zodziwika bwino zoziziritsira
1. Kuziziritsa kwachilengedwe kwa IC01 (kuziziritsa pamwamba)
Mwachitsanzo, ma mota a servo a Siemens compact 1FK7/1FT7. Dziwani: Kutentha kwa pamwamba pa mota yamtunduwu ndi kwakukulu, zomwe zingakhudze zida ndi zipangizo zozungulira. Chifukwa chake, m'mafakitale ena, kuyenera kuganiziridwa kuti tipewe kuwononga kutentha kwa mota kudzera mu kukhazikitsa mota komanso kuwononga pang'ono.
2. Kuziziritsa kwa IC411 (kudziziziritsa)
IC411 imaziziritsa mwa kusuntha mpweya kudzera mu kuzungulira kwa mota yokha, ndipo liwiro loyenda la mpweya limakhudzana ndi liwiro la mota.
3. Kuziziritsa kwa fan yokakamiza ya IC416 (kuziziritsa kwa fan yokakamiza kapena kuziziritsa kwa fan yodziyimira payokha)
IC416 ili ndi fan yoyendetsedwa yokha, yomwe imatsimikizira kuchuluka kwa mpweya kosalekeza mosasamala kanthu za liwiro la injini.
IC411 ndi IC416 ndi njira zoziziritsira zomwe nthawi zambiri zimagwiritsidwa ntchito pa ma mota a AC asynchronous omwe ali ndi mphamvu zochepa, ndipo kutentha kumatheka potulutsa nthiti zoziziritsira pamwamba pa mota ndi fan.
4. Kuziziritsa madzi
Kutentha komwe kumapangidwa ndi kutayika kwakukulu mu mota kumafalikira pamwamba pa mota kupita mumlengalenga wozungulira. Pamene mota ikugwira ntchito pansi pa mikhalidwe ina, pofuna kupewa kukwera kwa kutentha kwa magawo osiyanasiyana a mota, nthawi zina pamakhala njira zapadera kapena mapaipi odzazidwa ndi madzi m'malo otentha kwambiri a mota, ndipo mpweya wozungulira mkati mwa mota umapereka kutentha kwamkati ku bulangeti. Madzi ozizira pamwamba.
5. Kuziziritsa kwa haidrojeni
Mu makina amagetsi othamanga kwambiri, monga ma turbo-generator, kuziziritsa kwa hydrogen kumagwiritsidwa ntchito. Mu makina otsekedwa, mpweya wa hydrogen wokwera pang'ono kuposa mphamvu ya mlengalenga umayendetsedwa mkati ndi fan yomangidwa mkati, kenako umadutsa mu gawo lopanga kutentha la mota ndi chubu choziziritsira madzi motsatana.
6. Kuziziritsa mafuta
Mu ma mota ena, zigawo zosasuntha, komanso ngakhale zigawo zozungulira, zimazizidwa ndi mafuta, omwe amazungulira mkati mwa mota ndi kudzera mu zoziziritsira zomwe zimayikidwa kunja kwa mota.
2. Kugawa magalimoto kutengera njira yozizira
(1) Mota yachilengedwe yozizira sigwiritsa ntchito njira zapadera zoziziritsira mbali zosiyanasiyana za mota, ndipo imangodalira kuzungulira kwa rotor yokha kuti iyendetse mpweya.
(2) Gawo lotenthetsera la mota yodzipumira yokha limaziziritsidwa ndi fani yomangidwa mkati kapena chipangizo chapadera cholumikizidwa ku gawo lozungulira la mota.
(3) Mota yopumira mpweya wakunja (mota yoziziritsidwa ndi mpweya) Mbali yakunja ya motayo imaziziritsidwa ndi mphepo yopangidwa ndi fan yomwe imayikidwa pa shaft ya mota, ndipo mpweya wakunja sungalowe m'gawo lotenthetsera mkati mwa motayo.
(4) Kuzungulira kwa choziziritsira cha mota ndi zida zina zoziziritsira kumapangidwa ndi zipangizo zapadera kunja kwa mota, monga makabati oziziritsira madzi, makabati oziziritsira mpweya ndi mafani amagetsi a centrifugal eddy.
