kuyini emotweni - ukucacisa isifinyezo nesithombe
Okuqukethwe
Edivayisini yenjini, ingxenye ngayinye yenza umsebenzi othile. Kungakhathaliseki ukuthi induku yokuxhuma, iphinikhodi ye-piston noma uphawu lwamafutha e-crankshaft, ingxenye ephukile iholela emiphumeleni emibi. Enye yezinto ezibalulekile i-gasket Ikhanda le-cylinder - ikhanda le-cylinder. Kungani idingeka futhi yini esongela ukugqoka kwayo? Yiziphi izimpawu zokuthi i-cylinder head gasket ishaywe umoya? Sizocabangela le mibuzo esihlokweni sanamuhla se-vodi.su.
Head gasket: kuyini
Injini evuthayo yangaphakathi inezingxenye ezimbili eziyinhloko: i-cylinder block kanye nekhanda lebhulokhi. Ikhanda livala amakamelo omlilo, ama-valve kanye nomshini we-valve afakwe kuwo, futhi ama-camshaft afakwe kuwo. Ukusuka ngenhla ivaliwe ngesembozo se-block of valves. I-cylinder head gasket, njengoba ungase uqagele, itholakala phakathi kwe-cylinder block nekhanda.
Uma injini i-4-cylinder, khona-ke ku-gasket sibona ama-cutouts amane amakhulu ayindilinga, kanye nezimbobo zamabhawodi lapho ikhanda lixhunywe khona kubhlokhi, kanye neziteshi zokujikeleza koketshezi lwenqubo. Impahla eyinhloko yokukhiqizwa kwayo i-paronite eqinisiwe, futhi izimbobo zamakamelo omlilo zine-edging yensimbi. Ingase yenziwe ngensimbi encane yeshidi. Kukhona ezinye izinketho: ithusi, ukwakheka kwe-multilayer yensimbi ne-elastomer, i-asbestos-graphite.
Siphawula ngokushesha ukuthi i-cylinder head gasket ngokwayo ayibizi. Umsebenzi wokushintsha ubiza kakhulu, ngoba injini kufanele uyihlukanise, futhi ngemva kokuyishintsha, lungisa umshini wesikhathi nokusabalalisa kwegesi. Iyiphi imisebenzi eyenziwa yile pad?
- ukufakwa uphawu emakamelweni omlilo;
- ukuvimbela ukuvuza kwegesi enjinini;
- vimbela ukuvuza kwamafutha kanye nokupholisa;
- kuvimbela isipholile kanye nowoyela wenjini ekuxubeni.
Kodwa njengoba i-asbestos gaskets efakwe ezimotweni eziningi zanamuhla, zivele zishise ngokuhamba kwesikhathi, okudala isibonelo esibi kakhulu - amagesi avela kumagumbi omlilo angangena kumasekhethi okupholisa, futhi ama-coolant angena enjini. Kungani kuyingozi: ifilimu yamafutha igezwa ezindongeni ze-cylinder, ukugqoka kwabo okusheshayo kwenzeka, iyunithi yamandla ayipholi kahle, kungenzeka ukuthi i-piston jamming.
Ungaqonda kanjani ukuthi i-cylinder head gasket yephukile?
Uma i-cylinder head gasket idinga ukushintshwa, uzokwazi ngokushesha ngayo ngenani lezimpawu zesici. Okusobala kakhulu kubo intuthu eluhlaza okwesibhakabhaka evela kwipayipi yokukhipha, efana ne-steam. Lokhu kusho ukuthi i-antifreeze noma i-antifreeze ingena ngaphakathi kwebhulokhi. Ezinye izimpawu ezijwayelekile ze-cylinder head gasket eshaywayo:
- ukushisa kwenjini;
- amagesi angena ejazini lokupholisa, kuyilapho i-antifreeze iqala ukubilisa ethangini lokunweba;
- izinkinga lapho uqala injini - ngenxa ye-gasket eshisiwe, amagesi avela ekamelweni elilodwa angena kwelinye;
- ama-oily streaks lapho kuhlangana khona ikhanda le-cylinder kanye ne-cylinder block.
Ungaqaphela ukuthi uwoyela uxubene ne-antifreeze lapho ubheka izinga - iminonjana yegwebu elimhlophe izobonakala ku-dipstick. Amabala kawoyela abonakala ngeso lenyama endaweni yokupholisa amanzi. Uma i-antifreeze ne-grease kuhlanganiswa, kuzodingeka ushintshe i-gasket, usule uhlelo lokupholisa injini, ushintshe uwoyela.
Inkinga ilele eqinisweni lokuthi i-gasket breakthrough ayenzeki ngokushesha. Umgodi uyanda kancane kancane ngenxa yokucindezeleka kwenjini, ukucindezela okuphezulu, ukufakwa okungalungile, noma ukusetshenziswa kwezinto ezingabizi. Ama-detonations, esisanda kukhuluma ngawo ku-vodi.su, nawo aholela ekugqokeni kwe-cylinder head gasket.
Sicela uqaphele: abakhiqizi abazikhombisi izinsuku ezithile lapho le nto yokuvala idinga ukushintshwa. Ngakho-ke, ngephaseji ngayinye yokulungiswa, kuyadingeka ukuxilonga iyunithi yamandla yokuvuza kwamafutha nokupholisa.
Ukushintsha i-cylinder head gasket
Uma ubona okungenani eyodwa yezimpawu ezingenhla, udinga ukufaka esikhundleni se-cylinder head gasket. Kungcono uku-oda isevisi eziteshini zesevisi ezichwepheshile, lapho amathuluzi adingekayo etholakala khona. Inqubo yokukhipha "ikhanda" ngokwayo iyinkimbinkimbi, ngoba kuzodingeka unqamule inqwaba yezinzwa, okunamathiselwe, ibhande lesikhathi noma iketanga. Ngaphezu kwalokho, ama-bolts ekhanda le-cylinder aqiniswa nge-wrench torque. Kunamasu akhethekile endlela yokuqaqa futhi uwaqinise ngendlela efanele. Isibonelo, ukuqaqa ikhanda, udinga ukuguqula wonke ama-bolts ngamunye ngamunye, kusukela phakathi nendawo, isikhathi esisodwa ukuze ukhulule ukucindezeleka.
Ngemuva kokuthi ikhanda le-cylinder lihlakaziwe, indawo ye-gasket endala ihlanzwa kahle futhi ihlanjululwe. Entsha ibekwe phezu kwe-sealant ukuze ihlale endaweni yayo. Ukuqina kwama-bolts kufanele kwenziwe ngokuqinile ngokuya ngohlelo nge-torque yokuqinisa efanelekile. Ngendlela, ezimweni eziningi, lawa mabhawodi adinga ukushintshwa. Ngemva kokuphothula umsebenzi, umshayeli uqapha ukuziphatha kwemoto. Ukungabikho kokushisa ngokweqile, iminonjana yamafutha, njll. kuwubufakazi bokushintshwa okwenziwe kahle.
Iyalayisha...
