Mutu wa gasket. Ndi liti pamene iyenera kusinthidwa ndipo ndi ndalama zingati?
Pamakhala zovuta kwambiri pomwe mutu umalumikizana ndi cylinder block. Chisindikizo chomwe chimayikidwa pamenepo sichimapirira nthawi zonse kupanikizika ndi kutentha kwakukulu, ngakhale kuti chimakhala cholimba kwambiri. Zikawonongeka, mtengo wokonzanso ukhoza kufika ku zikwi za PLN.
Silinda yamutu wa gasket ndi chinthu chosavuta komanso chotsika mtengo. Pankhani yamagalimoto otchuka, mtengo wake sudutsa PLN 100. Komabe, imagwira ntchito yofunika kwambiri mu injini, kuyendetsa sikungagwire ntchito popanda izo. Tikukamba za kuonetsetsa kulimba kwa malo ogwira ntchito pamwamba pa pisitoni ndikusindikiza mayendedwe amafuta ndi ozizira. Mumphamvu kwambiri ndi injini turbocharged, mutu gasket akhoza kupangidwa kwathunthu zitsulo (zitsulo zosapanga dzimbiri, mkuwa), ndipo m'mbali pokhudzana ndi masilindala, akhoza kukhala wapadera, ang'onoang'ono flanges amapunduka moyenerera pambuyo kumangitsa mutu ndi kupereka mwapadera. kusindikiza bwino. Ngakhale gasket ochiritsira ali ndi elasticity ndi deformability, chifukwa chake, pamene mutu waumitsidwa, amadzaza zolakwa za yamphamvu chipika ndi yamphamvu mutu.
Akonzi amalimbikitsa: TOP 30 magalimoto okhala ndi mathamangitsidwe abwino kwambiri
Theoretically, silinda mutu gasket akhoza kukhala moyo wonse wa injini. Koma mchitidwewu ndi wosiyana kotheratu. Zomwe zimagwirira ntchito pagawo lagalimoto sizikhala zabwino nthawi zonse. Mwachitsanzo, ma motors amalemedwa kwambiri ndi ogwiritsa ntchito asanafike kutentha komwe kumafunikira. Kapena kutengera kutentha kwanthawi yayitali poyendetsa m'mapiri kapena m'misewu. Palinso omwe amathandizidwa ndi kukhazikitsa kwa HBO popanda kuwongolera koyenera. Mulimonsemo, ngakhale kuyika bwino kwa HBO popanda kukonzekera kozizira koyenera kumawonjezera kutentha m'zipinda zoyaka ndikuyika gasket pachiwopsezo. Mutha kuwonjezeranso zosintha zamakina zomwe sizimayendetsedwa mwaukadaulo mu injini. Muzochitika zonsezi, injini imatha kutenthedwa ngakhale mu imodzi mwa masilindala. The gasket si kupirira kupsyinjika matenthedwe ndi kuyamba kuwotcha kunja. Izi kawirikawiri zimachitika pakhosi pakati pa masilinda. Kuyatsa pang'onopang'ono pamapeto pake kumabweretsa kuphulika kwa mpweya wosakanikirana ndi mpweya wamafuta ndi mpweya wotulutsa mpweya pakati pa gasket, silinda block ndi mutu wa silinda.
Popeza gasket yonse imataya kulimba kwake pakapita nthawi, kutayikira kwamafuta oziziritsa ndi injini kumachitika. Chifukwa chake, pagawo loyambirira, kuwonongeka kwa cylinder head gasket kumawonekera pokhapokha ngati injini yozizira ikugwira ntchito komanso "kutayika" kwa liwiro lopanda ntchito. Ndi kusintha kwakukulu kwa kutentha kwa injini ndi kufooka kwa mphamvu yamagetsi ndi mapangidwe a utsi woyera kuchokera ku utsi, kukhalapo kwa mafuta mu thanki yowonjezera ya dongosolo lozizira (komanso kutaya madzimadzi), kukhalapo kwa ozizira mu mafuta - tiye ku workshop mwachangu. Makanikayo amatsimikizira kulephera kwa gasket poyesa kukakamiza kwa ma silinda ndikuwona ngati mpweya woipa uli mu thanki yokulirapo ya makina ozizirira.
Onaninso: Momwe mungasamalire matayala anu?
Pali mitundu yamagalimoto momwe cylinder head gasket imayaka mosavuta komanso ngakhale pamayendedwe abwinobwino, gasket imawonongeka. Pali zifukwa zosiyanasiyana zimene chizolowezichi chimalepherera. Nthawi zina izi zimachitika chifukwa cha kutsetsereka kwa liner ya silinda, ndipo nthawi zina chifukwa cha kupanikizana kwambiri kwa gasket, mwachitsanzo, chifukwa cha mtunda wocheperako pakati pa masilinda. Zingakhalenso chifukwa cha mapangidwe olakwika a injini yonse, yomwe imakonda kutenthedwa.
M'malo mwa silinda mutu gasket ndi ntchito yosavuta komanso yotsika mtengo kokha mu injini ziwiri sitiroko ndi anayi sitiroko injini ndi valavu pansi. Koma sagwiritsidwa ntchito m'magalimoto amakono. Ma injini omwe amapangidwa masiku ano ndi mapangidwe a ma valve apamtunda momwe ma valavu olowera ndi utsi amamangirira kumutu kwa silinda. Dongosolo lanthawi lomwe nthawi zambiri limapezekanso pamutu, ndipo kuyendetsa kwake kumayendetsedwa ndi crankshaft. Ichi ndichifukwa chake kuyika mutu wa gasket ndi ntchito yotengera nthawi komanso yokwera mtengo. Sikoyenera kusokoneza ndi kusonkhanitsa mutu wa silinda wokha, komanso kusokoneza ndikugwirizanitsa manifolds ndi kuyendetsa nthawi. Izi ziyenera kuwonjezeredwa masitepe owonjezera ndi zida zomwe zimafunika nthawi zambiri posintha mutu. Izi ndi, mwachitsanzo, zipilala zokhala ndi mtedza kumangiriza mutu wa silinda ku chipika cha silinda, chomwe chiyenera kusinthidwa ndi chatsopano (akale amatambasulidwa ndipo amatha kusweka). Kapena zobwezeredwa zomangira mabawuti, omwe nthawi zambiri amathyoka mukayesa kuwamasula (kumamatira chifukwa cha kutentha kwambiri). Maboti osweka ayenera kuchotsedwa pamutu, zomwe zimatenganso nthawi ya msonkhano. Zitha kupezekanso kuti mutuwo wapindika chifukwa cha kutentha kwambiri ndipo umafunika kukonzekera kukonzanso malo osasunthika bwino ndikuwonetsetsa kulimba.
Ngakhale zonse zitayenda bwino, kusintha gasket mumsonkhano wachinsinsi kumachepetsa chikwama chanu ndi PLN 300-1000 kutengera kukula ndi kapangidwe ka injini. Magawo adzagula PLN 200-300, ndipo zowonjezera zitha kuwononga PLN 100 ina. Ngati nkhaniyo yatsala pang'ono kusintha magawo a nthawi, muyenera kuwonjezera PLN 300-600 ya zida zosinthira ndi PLN 100-400 yantchito. Injini ikakhala yovuta kwambiri komanso yosafikirika kwambiri, mitengo yake imakwera. Pankhani yamagalimoto apamwamba okhala ndi injini zazikulu zovuta, mitengo imatha kukhala yokwera kwambiri.
