Chifukwa chiyani choyambitsa sichimayatsa kutentha

Nthawi zambiri choyambira sichimatentha chifukwa chakuti ikatenthedwa, tchire limakula pang'ono kukula kwake, chifukwa chake shaft yoyambira imazungulira kapena siyimazungulira konse. komanso zifukwa zomwe choyambitsa sichimayamba kutentha ndikuwonongeka kwa magetsi okhudzana ndi kutentha, kuipitsidwa kwa mkati mwake, kuphwanya gulu lolumikizana, kuipitsidwa kwa "pyatakov".

Kuti muthane ndi vutoli, muyenera kuchotsa zomwe zalembedwazo. Komabe, pali njira zingapo "za anthu" zomwe ngakhale choyambira chomangika chimatha kusinthasintha ndi kutentha kwakukulu.

Chifukwa cha kupsinjika	Zoti apange
Zovala za Bushing	Bwerezerani
Kuwonongeka kwa ma contacts	Yeretsani, sungani, tsitsani zolumikizana
Kuchepetsa kukana kwa insulation ya stator / rotor winding	Onani kukana kwa insulation. Kuthetsedwa ndi m'malo mapiringidzo
Kulumikizana ndi mbale mu solenoid relay	Chotsani kapena kusintha mapepala
Dothi ndi fumbi mu nyumba yoyambira	Yeretsani mkati, rotor/stator/contacts/chivundikiro
Kuvala burashi	Tsukani maburashi kapena kusintha gulu la burashi

Chifukwa chiyani choyambira sichikutembenuka chikatentha?

Mayeso oyambira amatha kuchitidwa ndi batri yodzaza kwathunthu. Ngati choyambitsa sichikutha kuyimitsa injini kuti itenthe kapena ikugwedezeka pang'onopang'ono, mutha kukhala ndi batire yofooka.

Pakhoza kukhala zifukwa 5 chifukwa sitata si kuyatsa yotentha, ndipo pafupifupi onse a iwo ndi mmene magalimoto ndi mtunda mkulu.

Zoyambira zoyambira

• Kuchepetsa tchire chilolezo. Ngati pakukonzanso kotsatira kwa zoyambira zoyambira kapena zonyamula zokhala ndi m'mimba mwake pang'ono zidayikidwa, ndiye mukatenthedwa, mipata pakati pazigawo zosuntha imachepa, zomwe zingayambitse kutsekeka kwa shaft yoyambira. Mkhalidwe wofananawo umawonedwa pamene tchire lokhazikika likutha. Pankhaniyi, rotor warps ndi kuyamba kukhudza maginito okhazikika.
• Kuwonongeka kwa kukhudzana ndi kutentha. Kulumikizana koyipa (kotayirira) kumatenthetsa palokha, ndipo ngati izi zichitika pa kutentha kwakukulu, ndiye kuti madzi osakwanira amadutsamo, kapena kukhudzana kumatha kutha. Nthawi zambiri pamakhala mavuto ndi waya kuchokera pa choyatsira chosinthira kupita ku choyambira (ma oxide) kapena nthaka yosauka kuchokera ku batri kupita koyambira. pakhoza kukhalanso zovuta mugulu lolumikizana ndi chosinthira choyatsira.
• Kuchepetsa kukana kwa mphepo. Ndi kuwonjezeka kwa kutentha, mphamvu yotsutsa ya stator kapena rotor yokhotakhota pa sitata imatha kutsika kwambiri, makamaka unityo ili kale. Izi zingayambitse kuchepa kwa mphamvu ya electromotive, ndipo motero, woyambitsayo adzatembenuka molakwika kapena osatembenuka konse.
• "Pyataki" pa retractor relay. Zowona za VAZ - "classic" magalimoto. M'malo mwawo retractor relay, pakapita nthawi, zomwe zimatchedwa "pyataks" - kutseka kulumikizana - zimayaka kwambiri. Amawotcha okha, monga momwe amagwiritsidwira ntchito, komabe, pa kutentha kwakukulu, khalidwe lolumikizana nalo limawonongeka kwambiri.
• Rotor yakuda. Pakapita nthawi, zida zoyambira zimadetsedwa ndi maburashi komanso pazifukwa zachilengedwe. Chifukwa chake, kukhudza kwake kwamagetsi kumakulirakulira, kuphatikizapo amatha kumamatira.

Zoyenera kuchita ngati choyambitsa sichikuyatsa ICE wotentha

Ngati choyambitsa sichingatembenuzire injini yoyaka mkati kukhala yotentha, ndiye kuti muyenera kuyichotsa ndikuyiyang'ana. Diagnostic algorithm idzakhala motere:

"Pyataki" retractor relay

• Onani masamba. Ngati tchire latha kwambiri ndipo kusewera kumawoneka, kapena mosemphanitsa, shaft yoyambira siyikuyenda bwino chifukwa cha iwo, ndiye kuti tchire liyenera kusinthidwa. Posankha iwo, onetsetsani kuti mukuganizira kukula komwe kumalimbikitsidwa ndi wopanga.
• Yang'anani zolumikizira zamagetsi. Onetsetsani kuti mwayang'ana zolumikizira zonse zamagetsi ndi mawaya. Ngati pali zolumikizana zosawoneka bwino, zimitsani, gwiritsani ntchito chotsukira. Chisamaliro chapadera chiyenera kuperekedwa kwa olumikizana nawo pa "nthaka", mu chosinthira choyatsira ndi cholumikizira pa retractor. Pa VAZs, nthawi zambiri palibe gawo la waya lokwanira kuchokera ku batri (zonse misa ndi zabwino) kapena chingwe chamagetsi kuchokera ku batri kupita ku zoyambira zimawola.
• Onani ma stator ndi ma rotor windings. Izi zimachitika pogwiritsa ntchito ma multimeter apakompyuta, osinthidwa kukhala ohmmeter mode. Ndi bwino kuyang'ana m'madera osiyanasiyana a injini yoyaka mkati, kuzizira, kutentha kwapakati komanso kotentha, izi zidzakuthandizani kumvetsetsa kuchuluka kwa kukana kwa insulation. Mtengo wofunikira ndi 3,5 ... 10 kOhm. Ngati ili m'munsi, ndiye kuti muyenera kusintha mafunde kapena choyambira chokha.
• Chongani "pyataki". Kuti muchite izi, chotsani cholumikizira cha solenoid kuchokera koyambira ndikuyeretsa bwino. Ngati apsa kwambiri ndipo sangathe kubwezeretsedwa, retractor (kapena choyambira chonse) chiyenera kusinthidwa. Ili ndi vuto wamba, chifukwa chake retractor sagwira ntchito yotentha.
• Onetsetsani kuti yayera chivundikiro, rotor ndi kunja kunja kwa sitator stator. Ngati zili zodetsedwa, ziyenera kutsukidwa. Poyamba, muyenera kugwiritsa ntchito kompresa mpweya, ndiyeno kuyeretsa ndi burashi ndipo, pamapeto pake, ndi sandpaper (400 kapena 800).

Popeza njira zonsezi zimatenga nthawi kuchotsa ndi kusokoneza msonkhanowo, njira zoyambira mwadzidzidzi zidzathandiza kuti atulukemo ndikuyambabe ICE yotentha ndi vuto loyambira.

Momwe mungayambitsire injini yoyaka mkati ngati choyambitsa sichiyamba kutentha

Pamene choyambitsa sichitentha, koma muyenera kupita, pali njira zingapo zadzidzidzi zoyambira poyambira. Amakhala ndi kutsekedwa kokakamiza kwa oyambira oyambira mwachindunji, ndikudutsa dera losinthira poyatsira. Adzagwira ntchito pokhapokha ngati pali vuto ndi retractor, kukhudzana ndi kuvala pang'ono kwa tchire; pazifukwa zina, muyenera kudikirira kuti zizizizira.

Malo oyambira ma terminals

Choyamba, komanso chogwiritsidwa ntchito kwambiri, ndikutseka zolumikizirana ndi screwdriver kapena chinthu china chachitsulo. Ndi kuyatsa, ingotsekani zolumikizira panyumba yoyambira. Zolumikizira zili kunja kwa nyumba zoyambira, mawaya amawakwanira. Muyenera kutseka choyimira kuchokera ku batire (waya wamagetsi, +12 Volts) ndi poyambira injini yoyambira. Simungathe kukhudza choyatsira moto, monganso simungathe kufupikitsa +12 V mpaka nyumba yoyambira!

Njira yachiwiri imaphatikizapo kukonzekera koyambirira, imagwiritsidwa ntchito pamene vuto likudziwika, koma palibe mwayi kapena chikhumbo chothana nacho. Chingwe cha mawaya awiri ndi batani lamagetsi lotseguka nthawi zambiri lingagwiritsidwe ntchito. Lumikizani mawaya awiri kumapeto kwa waya kwa oyambitsa, kenaka amayala chingwe mu chipinda cha injini kuti mapeto ake ena atuluke kwinakwake pansi pa "torpedo" ku gulu lolamulira. Lumikizani mbali zina ziwiri ku batani. Ndi chithandizo chake, mutatha kuyatsa choyatsira, mutha kutseka kutali ndi oyambira kuti muyambitse.

Pomaliza

Yoyambira, isanathe posachedwapa, imayamba kusatembenuza injini yoyaka mkati pamoto wotentha. Komanso, mavuto oyambira amatha kuchitika ndi mawaya ofooka ndi kulumikizana. Choncho, kuti musakhale mumkhalidwe wosasangalatsa wotere, muyenera kumutsatira ndi waya wake.
