ndi chiyani mu galimoto - decoding chidule ndi chithunzi
Zamkatimu
Mu chipangizo cha injini, gawo lililonse limagwira ntchito inayake. Mosasamala kanthu kuti ndi ndodo yolumikizira, pistoni kapena chisindikizo cha mafuta a crankshaft, gawo losweka limabweretsa zotsatira zoopsa. Chimodzi mwa zinthu zofunika kwambiri ndi gasket Mutu wa silinda - mutu wa silinda. Chifukwa chiyani ndikofunikira komanso zomwe zimawopseza kuvala kwake? Ndi zizindikiro ziti zomwe cylinder head gasket imawomberedwa? Tikambirana mafunso amenewa m’nkhani ya lero ya vodi.su.
Head gasket: ndi chiyani
Injini yoyatsira mkati imakhala ndi magawo awiri akulu: cylinder block ndi block head. Mutu umatseka zipinda zoyaka moto, ma valve ndi makina a valve amaikidwa mmenemo, ndipo ma camshaft amaikidwa mmenemo. Kuchokera pamwamba kumatsekedwa ndi chivundikiro cha chipika cha ma valve. Mutu wa silinda wa gasket, monga momwe mungaganizire, uli pakati pa chipika cha silinda ndi mutu.
Ngati injini ili ndi 4-silinda, ndiye mu gasket timawona ma cutouts anayi akuluakulu ozungulira, komanso mabowo a mabowo omwe mutuwo umamangiriridwa ku chipika, ndi njira zoyendetsera madzi amadzimadzi. Zinthu zazikulu zomwe zimapangidwira ndizolimbitsa paronite, ndipo mabowo a zipinda zoyaka moto amakhala ndi zitsulo zachitsulo. Ikhoza kupangidwa ndi chitsulo chochepa kwambiri. Palinso njira zina: mkuwa, multilayer zikuchokera zitsulo ndi elastomer, asbestos-graphite.
Timazindikira nthawi yomweyo kuti silinda mutu gasket palokha si okwera mtengo. M'malo ntchito ndi okwera mtengo kwambiri, chifukwa muyenera disassemble injini, ndipo m'malo izo, kusintha limagwirira nthawi ndi kugawa gasi. Kodi pad iyi imagwira ntchito zotani?
- kusindikiza zipinda zoyaka moto;
- kupewa kutuluka kwa gasi kuchokera ku injini;
- kuletsa kutayikira kwa mafuta ndi kozizira;
- imalepheretsa kusanganikirana kwa mafuta ozizirira ndi injini.
Koma popeza ma gaskets a asbestos amaikidwa pa magalimoto ambiri amakono, amangotentha pakapita nthawi, zomwe zimapanga chitsanzo chachikulu - mpweya wochokera m'zipinda zoyatsira moto ukhoza kulowa m'madera ozizira, ndikulowa mu injini yozizira. Chifukwa chiyani ndizowopsa: filimu yamafuta imatsukidwa pamakoma a silinda, kuvala kwawo kofulumizitsa kumachitika, gawo lamagetsi silimazizira bwino, kuthekera kwa piston kupanikizana.
Kodi mungamvetse bwanji kuti yamphamvu yamutu yamutu yathyoledwa?
Ngati silinda yamutu wa gasket ikufunika kusinthidwa, mudzadziwa mwachangu ndi zizindikiro zingapo. Chodziwika kwambiri mwa iwo ndi utsi wa buluu kuchokera ku chitoliro chotulutsa mpweya, chofanana ndi nthunzi. Izi zikutanthauza kuti antifreeze kapena antifreeze imalowa mkati mwa chipikacho. Zizindikiro zina zodziwika bwino za cylinder head gasket:
- kutenthedwa kwa injini;
- mpweya umalowa mu jekete yozizira, pamene antifreeze imayamba kuwira mu thanki yowonjezera;
- mavuto poyambitsa injini - chifukwa cha gasket yopsereza, mpweya wochokera kuchipinda chimodzi umalowa m'chipinda china;
- mikwingwirima yamafuta pamphambano ya mutu wa silinda ndi chipika cha silinda.
Mutha kuzindikira kuti mafuta akusakanikirana ndi antifreeze poyang'ana mulingo - mawonekedwe a thovu loyera adzawonekera pa dipstick. Madontho amafuta amawonekera m'maso mwamaliseche mumadzi ozizira. Ngati antifreeze ndi mafuta asakanizidwa, muyenera kusintha gasket, kutulutsa injini yozizira, kusintha mafuta.
Vuto lagona pa mfundo yakuti gasket yopambana sikuchitika nthawi yomweyo. Bowolo limakula pang'onopang'ono chifukwa cha kupsinjika kwa injini, kuponderezana kwakukulu, kuyika kosayenera, kapena kugwiritsa ntchito zida zotsika mtengo. Ma detonations, omwe takambirana posachedwa pa vodi.su, amatsogoleranso kuvala kwa cylinder head gasket.
Chonde dziwani: opanga samawonetsa masiku enieni pomwe chinthu chosindikizirachi chiyenera kusinthidwa. Choncho, ndi ndime iliyonse yokonza, m'pofunika kufufuza mphamvu ya mphamvu ya mafuta ndi kutayikira kozizira.
Kuchotsa silinda yamutu wamutu
Ngati muwona chimodzi mwazizindikiro zomwe tazitchula pamwambapa, muyenera kusinthira cylinder head gasket. Ndi bwino kuyitanitsa ntchitoyo kumalo osungirako akatswiri, komwe kuli zida zofunika. Njira yochotsera "mutu" yokha ndi yovuta kwambiri, chifukwa padzakhala kofunikira kuti mutulutse unyinji wa masensa, zomata, lamba wanthawi kapena unyolo. Kuphatikiza apo, ma bolts amutu wa silinda amalumikizidwa ndi wrench ya torque. Pali ziwembu zapadera za momwe mungatulutsire ndi kumangitsa bwino. Mwachitsanzo, kuti athetse mutu, muyenera kutembenuza mabotolo onse mmodzimmodzi, kuyambira pakati, nthawi imodzi kuti muchepetse nkhawa.
Mutu wa silinda utatha, malo a gasket akale amatsukidwa bwino ndikuchotsedwa. Chatsopanocho chimayikidwa pa chosindikizira kuti chikhale pamalo ake. Kulimbitsa ma bolts kuyenera kuchitidwa mosamalitsa molingana ndi chiwembucho ndi torque yabwino yolimba. Mwa njira, nthawi zambiri, mabawutiwa amafunika kusinthidwa. Akamaliza ntchito, dalaivala amayang'anira momwe injiniyo ikuyendera. Kusowa kwa kutenthedwa, zotsalira za mafuta, ndi zina zotero ndi umboni wa kusinthidwa kochitidwa molondola.
