Zomwe zimayambitsa fungo la mafuta m'galimoto

Fungo lachilendo, monga phokoso, mu kanyumba lingakhale losasintha, losokoneza kapena loopsa. Mafuta oyaka amagwera m'magulu atatuwa nthawi zosiyanasiyana. Zonse zimadalira chifukwa cha zochitikazo, kotero kuti zinthuzo zimafuna kuphunzira ndi kutanthauzira molondola.

Zomwe zimayambitsa fungo la mafuta oyaka mu kanyumba

Mafuta omwe ali m'mayunitsi amapangidwa m'mavoliyumu osindikizidwa ndi zisindikizo ndi zisindikizo. Kuonjezera apo, ulamuliro wake wotentha umayendetsedwa bwino, ndipo sayenera kuwotcha mu makina ogwira ntchito.

Inde, ndipo mafutawo amatha kupirira kutentha kwakukulu popanda makutidwe ndi okosijeni mofulumira, ndiko kuti, samatulutsa utsi ndi fungo lapadera ngakhale atakumana ndi mpweya wokhala ndi mpweya.

Koma pakakhala zovuta, zinthu zimasintha:

• mafuta amatha kutenthedwa mkati mwa mayunitsi, kuwononga zinyalala, kapena kungowonjezera oxidize pang'onopang'ono ndi kutulutsa utsi;
• kutuluka kapena kungodutsa mu mawonekedwe a nkhungu yamafuta kudzera mu zisindikizo, imatha kufika pazigawo zotentha zautsi ndi zotsatira zomwezo;
• pansi pa fungo la mafuta opsereza, zipangizo zina kapena zogwiritsira ntchito zikhoza kutsekedwa panthawi ya ntchito yachilendo komanso kutenthedwa.

Ngakhale zonsezi zitachitika, kununkhira kumafunikabe kulowa mnyumbamo. Kulimba kwake kumaperekedwa mosiyanasiyana, kumasiyana kwambiri mumitundu ndi mitundu yamagalimoto, komanso pamlingo wa kuwonongeka kwawo. Matupi ena amatha kumva fungo labwino ngakhale m'magalimoto oyandikana nawo akuyenda pang'onopang'ono.

Zomwe Zimayambitsa

Ndikofunikira kudziwa kaye komwe utsi umalowa mnyumbamo. Izi zitha kukhala mazenera otseguka, chishango cha injini, pansi kapena tailgate mu hatchbacks ndi ma station wagon.

Njira yodziwika bwino imathandizira kupeza ndi kukonza vutolo.

Fungo la mafuta oyaka mkati mwagalimoto 👈 zoyambitsa ndi zotsatira zake

Kununkhira kwa mafuta a injini

Magwero ambiri a utsi wa mafuta kuchokera pansi pa hood si nthawi zonse okhudzana ndi zovuta. Nthawi zambiri, izi ndi zotsatira za kukonza kapena kuyendetsa galimoto, pamene mbali zowonongeka zomwe zimakhala zodzaza mafuta nthawi yomweyo zimayamba kuyaka.

Utsi ukhoza kukhala wochuluka kwambiri, koma wopanda vuto lililonse, ndipo pambuyo pa kutha kwa mafuta kapena mafuta omwe agwera pazigawozo, amasiya.

Koma pali zifukwa zodetsa nkhawa kwambiri:

1. Kutayikira pa mphambano ya chivundikiro cha valve ndi mutu wa chipika. Gasket ya mphira yomwe ili pamenepo imataya mphamvu mwachangu ndipo siyikhala ndi chifunga chamafuta. Makamaka ngati chivundikirocho ndi pulasitiki kapena zitsulo zopyapyala, ndipo zilibe kukhazikika koyenera. Mafutawo adzagwera pamtundu wotentha wotentha, womwe uli pansi pa olowa, udzasuta pang'ono, koma nthawi zonse. Muyenera kusintha gasket kapena kukonzanso sealant.
2. Ndi kukakamizidwa kochulukira mu crankcase chifukwa cha kuvala kwa mphete za pisitoni kapena kusokonekera kwa mpweya wabwino wa crankcase, mafuta amayamba kufinyidwa pazisindikizo zonse, ngakhale pakhosi lodzaza. Injini yonseyo imakutidwa mwachangu ndi zolengeza, kuphatikiza mapaipi otulutsa. M`pofunika kuti azindikire galimoto ndi kuzindikira chifukwa cha kuchuluka kuthamanga.
3. Ngati zisindikizo za crankshaft ndi camshafts ziyamba kutha, ndiye kuti gawo lonse la m'munsi mwa injini lidzakhala mu mafuta, kuchokera pamene likhoza kulowa pansi pa mpweya wopita ku chitoliro chotulutsa mpweya. Zisindikizo zamafuta zowonongeka ziyenera kusinthidwa, panthawi imodzimodziyo kupeza chifukwa cha kuvala, sizingakhale zopanda khalidwe kapena ukalamba wa zisindikizo za mphete.
4. Crankcase gasket nayonso sikhala yamuyaya, monganso kumangirira torque yake. M'kupita kwa nthawi, zomangira zimafooka, poto imakhala mafuta. Nthawi zambiri kumangirira sikuthandizanso, ndikofunikira kusintha gasket kapena sealant.

Ndi kachitidwe kogwira ntchito bwino ka crankcase mpweya wabwino m'malo pansi pa ma pistoni, kupanikizika kumagunda, koma pafupipafupi sikuyenera kukhala kopitilira muyeso. Mutha kuyang'ana izi ndi choyezera chopondereza chokhala ndi zero pakati pa sikelo, ndikuchilumikiza kudzera pansonga yosindikizira ku dzenje la choyikapo mafuta. Chekecho chimachitika pama liwiro osiyanasiyana a crankshaft ndi malo opumira.

Kununkhira kwa mafuta kuchokera kumbali yopatsira

Zifukwa za kutulutsidwa kwa mafuta ku gearbox housings, kutengerapo nkhani ndi ma drive axle gearboxes ndi ofanana ndi injini. Palibe mpweya wotulutsa mpweya pano, kotero muyenera kuwonetsetsa kuti zopumira zomwe zimatulutsa magazi ochulukirapo pakasintha kwa kutentha zili bwino.

Kukonzanso kwina kumabwera ndikulowetsa zisindikizo, ma gaskets ndi zosindikizira zakale. Nthawi zina vuto la kusagwira bwino ntchito kwa zisindikizo zogwira ntchito bwino ndikugwedezeka ndi kubwereranso kwa ma bere pamitsuko kapena mafuta ochulukirapo kuposa momwe amachitira.

Zifukwa zina za fungo zimaphatikizapo kuwotcha mafuta m'mabowo a zotengera zodziwikiratu ndi fungo lofanana kwambiri lomwe limayambitsidwa ndi kuvala kwa zingwe zomangira pamanja.

Poyamba, pangakhale mavuto ndi bokosi, koma mafuta ayenera kusinthidwa mulimonsemo, ndipo kachiwiri, zonse zimadalira kutentha kwa disk yoyendetsedwa. Ndizotheka kuti sichinalandire kuwonongeka kosasinthika komabe, kwangotenthedwa kwanuko.

Kuwotcha fungo mu utsi

Ngati fungo la mafuta oyaka limalowa mu kanyumba kuchokera ku mpweya wotulutsa mpweya, ndiye choyamba muyenera kusamalira kulimba kwa dongosolo ndi thupi. Zonse zikakonzeka, palibe chomwe chiyenera kulowa mu kanyumbako. Kuopsa kwake sikuli mu mafuta, koma muzinthu zovulaza mu mpweya wotulutsa mpweya.

Mafuta omwewo amadyedwa ndi zinyalala m'mainjini ambiri, ndipo sikuti nthawi zonse ndi chizindikiro cha kusagwira ntchito bwino. Pali malamulo ogwiritsira ntchito malita pa 1000 kilomita. Mulimonsemo, ngati lita imodzi kapena kuposerapo idyedwa, ndiye kuti muyenera kuyang'ana chifukwa chake.

Itha kukhala:

• zisindikizo za valve zowonongeka kapena zowonongeka;
• kuvala ndi kung'amba mphete za pistoni;
• kuwonjezeka kwapakati pakati pa pistoni ndi silinda;
• mafuta otsika mu injini kapena kuchuluka kwake;
• mavuto ndi turbocharger unit.

Galimoto ingafunike kukonzanso mosiyanasiyana, koma ngakhale m'magalimoto osuta kwambiri, fungo lamafuta otenthedwa mkati mwake silingalowe m'chipinda chokwera. Chifukwa chake, muyenera kuyang'ana kutayikira m'thupi, komanso malo opitilira dzimbiri lazinthu zautsi. Zomwe, kuwonjezera pa fungo, zidzaperekanso phokoso losasangalatsa kwambiri.
