Engine dongosolo kuzirala: chipangizo, mfundo opaleshoni, vuto

Engine dongosolo kuzirala - mbali kofunika kwambiri. Popanda kutentha mkulu komwe kumachitika nthawi kuyaka wa osakaniza mafuta, ingomusiyani iyenda. Lomwe mfundo ndi mbali ya dongosolo kuzirala, ndipo kodi vuto ndi yodziwika?

Kulengedwa ndi Ntchito

Kuyamba, tiyeni kuthana ndi chipangizo. Modern galimoto dongosolo yozizira, yeniyeni, injini ya galimoto, amakhala kufunika ntchito mode kudzera madzi wapadera yozizira amene akufalitsa mwa jekete madzi - cavities wapadera mu chipika yamphamvu. Komanso jekete ya dongosolo yozizira zikuphatikizapo: a rediyeta, njira imodzi mpope madzi, mapaipi, fani, filler khosi. Redieta ndi chipangizo chimene akamazizira madzimadzi kudzera Mpweya chimadza, zimakupiza kumaliseche. Imodzi - ndi valavu chipangizo amene nthawi kufalitsa coolant mu dongosolo kuzirala. Mpope ndi fani, monga ulamuliro, nizitengedwa ndi malamba pagalimoto. Umo ndi momwe injini madzi dongosolo kuzirala ntchito pa magalimoto amakono kwambiri.

Kodi dongosolo kuzirala? Pa chiyambi-mmwamba valavu imodzi ndi udindo chatsekedwa, kulola madzimadzi kuti zimafala mwa bwalo otchedwa kakang'ono - mpope chimaposa madzi ake okha jekete. Pamene injini umafunda ndi kutentha madzi ukufika madigiri 80-95 Celsius (malingana ndi injini), valavu imodzi chimatsegula ndi madzimadzi amalowa rediyeta ya mutu yamphamvu. makope amenewa amatchedwa bwalo lalikulu. Kudutsa rediyeta madzimadzi ndi utakhazikika ndi akulowa mpope. Popeza dongosolo injini kuzirala amakhala ndi wabwinobwino ntchito mode.

malfunctions

Tsopano zolakwa. Iwo akhoza chifukwa cha kuwonongeka zachilendo ndipo kuichotsa wa munthu zigawo zikuluzikulu mu njira, ndi kukonzanso mtsogolo. Mwachitsanzo, injini kutenthedwa angayambe mwina chifukwa kuvala za valavu imodzi (atayamba kutsegula ndi akuchedwa kapena oyambirira), ndi chifukwa chakuti rediyeta selo mutadzala zinyalala. Kodi kuti apewe injini msanga kukonza dongosolo yozizira?

Choyamba, nthawi zonse kuyendera injini ndipo izikhala yoyera. Samalani mlingo coolant mu thanki patsogolo. Ngati ndi pansi, fufuzani zikayamba a mipope kuti kulumikiza rediyeta ndi madzi jekete. N'zotheka kuti zidzachitika. Malo kutayikira akhoza kumata sealant, koma ndi bwino kuti bondo ndalama ndi kugula kolala yachibadwa. Imfa ya dongosolo zingasonyeze kutayikira ndi kuwira madzi pa kutentha pamwamba 105 ° C. Koma rediyeta, izo tikulimbikitsidwa kuti zonse oyera kuchokera ku dothi, kuchapa ndi oyera madzi chubu pamene yatsekera, mafuta shutter khungu graphite lubricant. Njinga kutenthedwa m'chilimwe ingayambe ndi wonongeka ya mpope kapena zimakupiza. Pakuti mfundo izi, nthawi zonse funsani maganizo a lamba pagalimoto komanso kusintha ngati pakufunika kutero.

Komanso kulabadira coolant lapansi. Popeza zoletsa kuwuma chofunika kawetedwe ndi chiwerengero madzi ambiri, onetsetsani madzi kuwonjezera. Mulimonsemo sayenera kuthira madzi dongosolo mpopi. Izi kufulumizitsa mapangidwe lonse mu dongosolo. Kuchepetsa zoletsa kuwuma ndi madzi otchezedwa yekha! akatswiri amalangiza kuwonjezera coolant ndi wapadera odana ndi dzimbiri zowonjezera kuchepetsa zotsatira zikuwononga madzi injini. Ngati lonse mpaka pano (izo Tingaone pamene ankatenthetsa rediyeta), ndiye kuchititsa kuyeretsa mankhwala. Chifukwa chaichi pali kukonzekera mwapadera. Scale akhoza zimachitika mu dzenje kuda - Pankhaniyi ziyenera kutsukidwa waya kenako kuwomba wothinikizidwa mpweya.
