Nyumba zamagalimoto ndi zovuta ndi kasinthasintha wake. Kodi mungadziwe bwanji kuti vuto lili mmenemo?

Ndikosowa kwambiri kuti vuto la kupanga lipangitse chipolopolo chonyamula chizungulire mu mota. Nthawi zambiri izi zimachitika chifukwa cha kusasamala pantchito. Nyumba ya injini idapangidwira zolemetsa zazikulu zomwe zimachitika chifukwa chogwiritsa ntchito ndodo yolumikizira ndi pistoni. Komabe, chifukwa chogwiritsa ntchito kwambiri, imatha kupindika. Zotani pankhaniyi? Kodi kusintha kwa crankcase ya injini kumawononga ndalama zingati? Zonsezi (ndi zina zambiri) mudzaphunzira powerenga nkhani yathu!

Injini yokhala ndi chipolopolo - ndichiyani?

Ichi ndi chimodzi mwa zigawo za plain bearings. Kuyika ndodo yolumikizira kuli pa shank ndi mutu wake. Maonekedwe ake amafanana ndi kanyenyezi. Lili ndi malo athyathyathya, omwe ayenera kukhudzana ndi malo omangirira pa ndodo yolumikizira. Pamwamba pa zigawozi pali grooves kuonetsetsa kuyenda ndi kugawa yeniyeni mafuta injini. Zingwe za crankshaft zimakwanira mbali zonse za socket ndodo yolumikizayomwe imayikidwa pamtengo.

Kuzungulira kwa acetabulum - chifukwa chiyani izi zimachitika?

Chipolopolo cha injini chimathandizira kuchepetsa kukangana pakati pa zinthu za piston-crank system. Komabe, pamafunika mafuta a injini kuti agwire ntchito bwino. Kodi chifukwa chachikulu cha kulephereka kwa kubereka ndi kupotoza kwa chinthu ichi ndi chiyani? Izi makamaka ndi kunyalanyaza kwa nthawi ya mafuta. Kupanda mafuta ndi njira yogwira ndi kuzungulira acetabulum. Ngati vuto lichitika, dalaivala amatha kuzindikira zizindikiro popanda kuchotsa pansi pa injini.

Anatembenuza chikho - zizindikiro 

Zitsamba zotha, zopindika chifukwa cha kukangana, zimayamba kugogoda momveka bwino pamene pisitoni ikugwira ntchito. Zimenezi tingaziyerekeze ndi kumenya nyundo yachitsulo pa chinthu china. Phokoso silingasokonezedwe ndi lina lililonse. Nthawi zambiri, mumamva ziboliboli zowonongeka pa liwiro lalikulu la injini, koma nthawi zambiri mudzawona kugogoda kosiyana kuyambira mutangoyamba kuyendetsa.

Zowonongeka zonyamula chipolopolo - zotsatira za kuyendetsa galimoto ndi kuwonongeka

Pambuyo pozindikira vuto ndi nyumba ya injini, musapite patsogolo. Chifukwa chiyani? Kuperewera kwa mafuta pa shaft magazine ndi kuzungulira kwa chipolopolo chonyamula kumapangitsa kuti pakhale crankshaft pamalo ovuta. Chombo chowonongeka cha injini chingathenso kuwonongedwa ndi ntchito ndikumasula zojambula zachitsulo mu mafuta. Ngati utuchi ulowa m'zigawo zina za injini, umakanda pamwamba kapena kutseka njira zamafuta.

Momwe mungadziwire mayendedwe owonongeka a crankshaft?

Njira zocheperako zodziwira ma fani a shaft ndi awa:

• kuzimitsa ma coil poyatsira pamene unit ikuyenda;
• kuzungulira kwa tsinde ndi kukhudza pamwamba pa pisitoni ndi chinthu cholimba (chopanda kukanda).

Njira yoyamba ndiyomwe imatenga nthawi yochepa ndipo simuyenera kuwerengera zinthu zambiri. Ngati mukukayikira kuti chikwama cha injini chatembenuka, yambitsani makinawo ndikudula ma koyilo pa silinda imodzi imodzi. Kumbukirani kuchita mosamala. Zachidziwikire, mota yopanda chonyezimira idzalephera pa silinda iyi, koma mukapeza yoyenera, kugogodako kumachepa.

Momwe mungayang'anirenso ngati vuto lili m'nyumba zamagalimoto?

Mutha kuyesa njira zotsatirazi pamainjini a dizilo pomwe njira yapitayi sinagwire ntchito. Makapu ozungulira amapereka zizindikiro za kugwedeza, komanso kuwonjezera malo pakati pa phazi ndi chidutswa chosweka. Kodi kufufuza? Muyenera kutenga chinthu chachitali komanso cholimba (monga screwdriver) ndikutembenuzira shaft mpaka pisitoni ituluke mu TDC. Kenako kanikizani screwdriver mwamphamvu pamwamba pa pisitoni. Ngati mukumva ndikudina kosiyana, ndiye kuti chipolopolo cha injini mu ndodo yolumikizira iyi chalephera.

Kusintha kwa injini mu injini - mtengo

Kuti muchotse vutolo, muyenera kuchita kukonzanso kwakukulu kapena kubwezeretsa injini. Muyenera disassemble m'munsi mwa chipika ndi kuchotsa injini crankshaft magazini, mayendedwe ndi china cholumikizira ndodo. Soketi yotembenuzidwa imafunikira osati kungosintha zida ndi zatsopano, komanso kuyang'ana zinthu zina zolumikizirana. Nthawi zambiri, crankshaft ndi ndodo zolumikizira ziyenera kupangidwanso ndi makina. Uwu ndiye mtundu wabwino kwambiri, chifukwa nthawi zambiri chipika cha injini chimatha kulephera. Chivundikiro chagalimoto chosalongosoka chidzapangitsa kukonza kapena kusinthanso galimotoyo.

Nyumba za injini - momwe mungapewere kuwonongeka

Kumbukirani kuti kulephera kwamtunduwu sikuchitika kawirikawiri chifukwa cha vuto la kupanga. Kupatulapo ndi gawo la 1.9 dCi lochokera ku Renault. Kutalikirana kwambiri ndi mpope wamafuta kudakakamira momwemo chifukwa chosowa mafuta. Kuti mupewe kuwonongeka koteroko, sinthani mafuta pafupipafupi pakapita nthawi ndikugwiritsa ntchito mafuta ofunikira a injini yanu.

Nyumba ya injini ndi chinthu chaching'ono, koma chofunikira kwambiri pakugwiritsa ntchito bwino mphamvu yamagetsi. Kuti musawononge ndalama zambiri kuti musinthe injini yonse, samalirani kusintha kwamafuta nthawi zonse, ndipo ngati muli ndi zizindikiro zoopsa, musachepetse kugogoda.
