Zisindikizo zowola za valve

Zisindikizo za nthawi, zomwe zimadziwika kuti "valve seals", zimateteza mafuta kuti asalowe mutu wa silinda m'chipinda choyaka pamene ma valve atsegulidwa. gwero zigawo izi ndi pafupifupi 100 Km., koma ndikugwira ntchito mwaukali, kugwiritsa ntchito mafuta otsika kwambiri komanso mafuta opangira mafuta komanso pakatha nthawi yayitali ya injini yoyaka mkati (kuposa chaka), kuvala kwa zisindikizo za valavu kumachitika mwachangu. Chifukwa cha kuvala kwa chisindikizo mafuta amalowa mu chipinda choyaka moto, chifukwa chomwe injini imataya mphamvu komanso yosakhazikika, kugwiritsa ntchito mafuta kumawonjezeka kwambiri.

Momwe mungadziwire kuvala kwa zisindikizo za valve ndi momwe mungathetsere - tidzakuuzani m'nkhaniyi.

Zizindikiro za ma valve otsekedwa

chizindikiro choyambirira cha kuvala kwa zisindikizo za tsinde la valve - utsi wabuluu kuchokera ku chitoliro chotulutsa poyambira ndi kupuma pambuyo pa kutentha. Mukatsegula khosi lodzaza mafuta pa injini yoyaka mkati, utsi ukhoza kutuluka pamenepo, ndi m'zitsime za makandulo ndipo pa zingwe za waya kapena zoyatsira ndi zotheka masamba mafuta. Mafuta opaka mafuta amapezekanso pa ulusi ndi ma electrode a spark plugs.

Kupaka mafuta pa ulusi wa kandulo

Kulowetsedwa kwa mafuta m'chipinda choyaka moto kumayambitsa kuyika kwa zigawo za CPG, zomwe zimadzaza ndi kutenthedwa kwa ma valve ndi zochitika za mphete za pistoni. M'kupita kwa nthawi, izi zingayambitse kufunikira kokonzanso injini. Kuchulukitsa kwamafuta ndikowopsanso - ndikuwonjezera mosayembekezereka, kutenthedwa, kugoletsa komanso ngakhale kupanikizana kwa injini yoyatsira mkati ndikotheka. Zizindikiro za zisindikizo za valve zowonongeka ndizofanana ndi zizindikiro za mavuto ena omwe amachititsa kuti mafuta aziwotcha, choncho choyamba muyenera kuonetsetsa kuti vutoli lili muzitsulo za valve.

Momwe mungadziwire kuvala kwa zisindikizo za tsinde la valve

Zizindikiro zonse za kuvala kwa chisindikizo cha valve, zomwe zimayambitsa ndi njira zodziwira zomwe zimayambitsa izi zikufotokozedwa mwachidule mu tebulo ili m'munsimu kuti zikhale zosavuta.

Chizindikiro	Zimayambitsa maonekedwe	Zotsatira	Njira zodziwira
Utsi wabuluu ukutuluka mu utsi	Mafuta otuluka kuchokera kumutu wa silinda kupita kuchipinda choyaka moto m'khosi la valve amawotcha pamodzi ndi mafuta ndipo zinthu zake zoyaka zimapaka utoto wabuluu.	Zinthu zoyaka moto zamafuta zimapanga soot, mphete "zimagona", ma valve salinso bwino ndipo amatha kutentha. Ngati mulingo wothira mafuta ugwera m'munsimu, injini yoyaka mkati imatha kulephera chifukwa cha njala yamafuta.	Yambitsani injini yoyaka mkati mutatha maola 2-3 kapena kufinya mwamphamvu chopondapo chamafuta pansi kwa masekondi 2-3 osagwira ntchito ndi injini yofunda. Unikani kukhalapo ndi mtundu wa utsi.
Mpweya madipoziti pa maelekitirodi makandulo, wochuluka ulusi	Mafuta owonjezera kuchokera m'chipinda choyaka moto amafinyidwa mu ulusi wa makandulo, koma o-ring amalepheretsa kutuluka.	Kuwotcha kumawonjezereka, chifukwa chomwe kusakaniza kwamafuta a mpweya kumayaka kwambiri, injini imayamba kugwira ntchito mosakhazikika. Pa jakisoni ICEs, ECU imazindikira zolakwika ndikuyesa kukonza mwa kusintha kukula kwa gawo lamafuta obaya ndi nthawi yoyatsira. Chifukwa cha izi, kugwiritsa ntchito mafuta a petroli kumawonjezeka ndipo mphamvu imatayika.	Tsegulani makandulo ndikuyang'ana maelekitirodi awo, komanso ulusi wopaka mafuta ndi mwaye.
Kuchulukitsa kugwiritsa ntchito mafuta	Mafuta amalowa momasuka m'chipinda choyaka moto kudzera m'zisindikizo za valve zowonongeka, zomwe zimayaka pamodzi ndi mafuta.	Kugwira ntchito kwa injini kumawonongeka, mitundu ya mwaye m'masilinda, komanso kutsika kwakukulu kwamafuta kumatha kupha injini yoyaka mkati.	Yang'anani nthawi zonse mulingo wamafuta mukafika pamtunda wina wamtunda. Kugwiritsa ntchito mafuta pamene zisindikizo za valavu zimavala zimafika pa 1 l / 1000 km ndi zina zambiri.
Kuvuta kuyambitsa injini yozizira	Mafuta akuyenda kuchokera kumutu wa silinda amaunjikana pa ma valve ndi ma pistoni, "kuponya" makandulo. Popeza kutentha kwake koyatsa kumakhala kokwera kwambiri kuposa mafuta kapena gasi, ndipo kandulo yopaka mafuta imatulutsa kuwala koyipa, zimakhala zovuta kuyatsa chisakanizo chokhala ndi mafuta.	Katundu pa batri amawonjezeka, moyo wake wautumiki umachepetsedwa. Makandulo m'mafuta amagwiranso ntchito kwambiri, chifukwa amaphimbidwa ndi mwaye. Zotsalira za mafuta osatenthedwa zimawononga chothandizira ndi ma probe a lambda, ndikuchepetsa moyo wawo.	Ndi kuzizira koyambira, kuchuluka kwa zosinthira zoyambira kumawonjezeka mpaka injini itayamba.
Utsi wabuluu umachokera ku khosi lodzaza mafuta	Mpweya wotulutsa mpweya panthawi yotsegula valavu kudzera mu bokosi lotayirira lotha kulowa mumutu wa silinda ndikutuluka pakhosi.	Mafuta amadzaza ndi zinthu zoyaka moto, chifukwa chake amasintha mtundu wake mwachangu ndikutaya mafuta ake oyambira komanso oteteza.	Tsegulani kapu yodzaza mafuta pomwe injini ikugwira ntchito.

Pagalimoto yokhala ndi chosinthira chothandizira chothandizira, utsi wabuluu ukhoza kukhala kulibe, chifukwa umawotcha zinthu zoyaka mafuta. Pamaso pa neutralizer, samalani kwambiri ndi zizindikiro zina!

Momwe mungamvetsetse: kuvala kwa zisindikizo za valavu kapena vuto mu mphete?

Kuzindikira kwa kuvala kwa tsinde la valve sikungotengera njira zowonera. Zizindikiro zomwezi zitha kuwonetsa zovuta zina, monga kuchitika kapena kuvala kwa mphete za pisitoni kapena makina opumira a crankcase osagwira ntchito. Kuti musiyanitse zizindikiro za kuvala kwa ma valve ndi zovuta zina, muyenera:

Momwe mungadziwire kuvala kwa zisindikizo za valve ndi endoscope: kanema

• Onani kupsinjika kozizira komanso kotentha. MSC ikavala, kukakamiza kwa masilinda nthawi zambiri kumakhala kwabwinobwino chifukwa chamafuta ambiri a zigawo za CPG. Ngati kuzizira kozizira kumakhala koyenera (10-15 atm kwa petulo, 15-20 kapena kuposa atm ya injini ya dizilo, malingana ndi kuchuluka kwa psinjika kwa injini), koma pambuyo pa opaleshoni yochepa (isanayambe kutentha) imachepa, pakhoza kukhala mavuto ndi zipewa. Ngati ndi otsika pozizira komanso mutatha kutenthetsa, koma amawuka pambuyo pobaya 10-20 ml ya mafuta mu masilindala, vuto liri mu mphete kapena kukula kwa silinda.
• Chotsani chitoliro chopumira pamene injini ikuyenda.. Ngati utsi wabluu watuluka pakhosi podzaza mafuta, muyenera kuchotsa chitoliro cholowera mpweya kuchokera pa crankcase kupita kumutu wa silinda (bowo lake pamutu liyenera kuphimbidwa kuti mpweya usatayike). Ngati zisindikizo za valve zavala, utsi umatulukabe pakhosi. Ngati vuto liri mu mphete kapena masilindala, utsi umatuluka mu mpweya.

Utsi wa buluu wochokera ku chitoliro chothamangitsa panthawi yoyambira umasonyeza kukhalapo kwa mafuta m'chipinda choyaka.

• Dziwani nthawi zomwe zimasuta kuchokera ku utsi. Pamene zisindikizo za valve zavala, utsi wa buluu umatuluka kuchokera ku mpweya panthawi yoyambira (chifukwa mafuta achulukana m'chipinda choyaka moto) komanso panthawi ya ressing pambuyo pa kutentha (chifukwa pamene phokoso likutseguka, mafuta amayamwa muzitsulo). Pambuyo pobwereza pang'ono, utsi ukhoza kutha. Ngati mphete za pisitoni zowotcha mafuta zili zolakwika, ndiye kuti zimasuta nthawi zonse, ndipo liwiro likakwera, utsi wake umakhala wamphamvu.
• Yang'anani ma discs a valve ndi endoscope. Injini yoyatsira mkati iyenera kuloledwa kuziziritsa, kenako kumasula makandulo ndikuwunika ma valve ndi endoscope kudzera mu zitsime za makandulo. Ngati zisindikizo za valve sizigwira mafuta, ndiye kuti pang'onopang'ono zidzayenda pansi pa makosi awo, ndikupanga madontho a mafuta pazitsulo za valve ndi mipando. Ngati pali kutayikira kwamphamvu kwa zisindikizo za valavu, ndizotheka kuti madontho amafuta alowe pa pistoni. Ngati ma valve ndi owuma, ndiye kuti vuto liri mu mphete.

Momwe mungakonzere zisindikizo za tsinde za ma valve zomwe zikutuluka

Ngati zisindikizo za valve zikutuluka, pali njira ziwiri zothetsera vutoli:

• kusintha zisindikizo za tsinde la valve;
• gwiritsani ntchito zowonjezera zowonjezera.

Kusintha zisindikizo za valavu ndi njira yowonongeka yomwe imafuna kulowererapo pamutu wa silinda. Pa ma motors ambiri, disassembly yapang'ono ya mutu idzakwanira, koma pazitsanzo zina ziyenera kuchotsedwa kwathunthu.

Chida chodzipangira tokha chochotsera zisindikizo zamafuta pazitsulo

Kuti musinthe zisindikizo za valve, muyenera:

• ma wrenches / mitu ndi screwdrivers (nambala zimadalira mtundu wagalimoto);
• valve desiccant;
• wrench kwa kupsinjika kwa lamba wa nthawi;
• collet cap remover, kapena pliers zazitali zamphuno zogwira mozungulira, kapena tweezers zamphamvu;
• ndodo yosinthika ya malata mpaka 1 cm mulifupi ndi 20-30 cm kutalika;
• mandrel chubu kwa kukanikiza zisindikizo zatsopano.

mudzafunikanso kugula zisindikizo zokha, chiwerengero chake ndi chofanana ndi chiwerengero cha ma valve mu injini yoyaka moto.

kuti mulowe m'malo mwa MSC, muyenera:

Nthawi ndi momwe mungasinthire zisindikizo za valavu: kanema

1. Chotsani ma spark plugs ndikuchotsa chophimba cha valve (zophimba pa injini zoyatsira mkati zooneka ngati V).
2. Tsegulani lamba ndikuchotsa camshaft (ma shafts pa V-woboola pakati ndi DOHC motors).
3. Chotsani valavu pusher (chikho), compensator hydraulic, kusintha washer kapena mbali zina zomwe zimalepheretsa kupeza "crackers".
4. Yambani valavu ndikuchotsa kasupe.
5. Pogwiritsira ntchito koleti, pliers zazitali zamphuno kapena tweezers, chotsani bokosi lakale loyikapo pa valve.
6. Thirani tsinde ndi mafuta ndikusindikiza pa kapu yatsopano ndi mandrel.
7. Sonkhanitsani choyendetsa valavu motsatira dongosolo.
8. Bwerezani masitepe 4-8 pa ma valve ena.
9. Ikani camshaft ndikugwirizanitsa ma shafts molingana ndi zizindikiro, limbitsani lamba wa nthawi, malizitsani msonkhano.

kuti valavu isalowe mu silinda, iyenera kuthandizidwa kudzera mu kandulo bwino ndi malata! Njira zina ndikukakamiza kompresa kudzera mu kandulo bwino ndikuyika chipinda choyaka ndi chingwe cholimba (mapeto ayenera kukhala kunja).

Kusintha zisindikizo za valve pamalo operekera chithandizo kumawononga ma ruble 5 (kuphatikiza mtengo wa zisindikizo zatsopano). Nthawi zina, mutha kuchotsa kutayikirako mothandizidwa ndi chemistry yapadera.
