Decalinate ndi kuyeretsa ma valve

Maphunziro: Kuchotsa, Kuyeretsa ndi Kudutsa Mavavu

6 Kawasaki ZX636R 2002 Sports Car Restoration Saga: Episode 12

Vuto la injini zoyatsira mkati ndi ma hydrocarbon osatenthedwa omwe amakhazikika m'chipinda choyaka cha injiniyo ndikuwala ndi kutentha kupanga zotsalira za kaboni. Ndizodetsadi zomwe zimalepheretsa injini kuti isagwire bwino ntchito, ndipo zotsatira zake zoyambirira zimakhala kutaya mphamvu komanso kuvala ma valve. Choncho, m'pofunika kuyeretsa, kapena m'malo decalamine, kuti injini kubwerera ntchito bwinobwino.

Vavu yotengera, kaya yoyambirira kapena yosinthika, ndiyokwera mtengo. Yembekezerani kuchokera ku 40 mpaka 200 euro pa valve, kutengera kapangidwe kake ndi zinthu. Choncho, m'pofunika, makamaka pamene injini kale dismantled, kuthera nthawi kuyeretsa ndi kubwezeretsa bwino. Valavu ndi gawo laling'ono, koma lili ndi magawo ambiri omwe ali ndi tanthauzo lawo.

Mbali zosiyanasiyana za valve

Injini yathu ya 4-silinda ili ndi mavavu 16. Izi zimagwirizana ndi bwalo laling'ono lililonse lomwe likuwonetsedwa pachithunzi cha mutu wa silinda wophwanyidwa. Tangoganizirani mtengo wake, kapenanso kusunga ndalama kudzera muzakudya.

Lowetsani ndi mavavu musanayeretse

Mosiyana ndi zimenezi, sindingafune kudziphonya poyeretsa kapena kupasula/kumanganso. Komanso, chida chapadera chimafunika kumasula kasupe ndikuchotsa.

Mwamwayi, ngakhale kuti ndinali ndi tsoka, lomwe nthawi zambiri limandivutitsa, ndimakumana ndi anthu okongola. Édouard, njonda yamakaniko a Rollbiker ku Boulogne, Billancourt, amandipatsa chithandizo chake. Ndi pa upangiri wake wanzeru ndi waubwenzi kuti ndipite kunyumba kwake, mutu wa silinda uli m'manja, kukachita maphunziro ofulumira amakina ndikuwonetsa kuyeretsa kwathunthu ndikudutsa ndi valavu. Mkhalidwe wawo woyipitsidwa ndi wofunikira ndipo mawonekedwe awo sakhala owala kwambiri, tiyeni tiwone zomwe wophika wathu wolemekezeka komanso makanika waku Boulogne angachite.

Zonsezi sizosangalatsa kwambiri ndipo, koposa zonse, palibe funso lowasiya m'dera lino.

Iye amandikomera manja, kunditonthoza komanso kundiponya m’bafa lalikulu kuti ndiphunzire kusambira. Ngakhale zili bwino, amandipatsa zida zofunika kuti ndibwerere ku garaja kukatenga nawo mbali. Mulole iye ayamikidwe kambirimbiri. Ndiye ndikunyamuka ndi chonyamulira ma valve odzaza masika ndikumangirira. Kumbali ina, phala laling'ono lili pamalo okondedwa a ZX6R 636, komwe ine ndi Alex tidzamaliza kuyendetsa. Kwa osadziwa, ndikufufuza mwatsatanetsatane phunziroli.

Zida zofufuzira zapadera

Zida zosinthidwa zilipo pa intaneti. Ine ndinayang'ana, basi.

Vavu spring compressor ikuwonetsedwa pamtengo woyambira pafupifupi ma euro 20. Tarifi yomwe mtengo wa valve wokwera uyenera kuwonjezeredwa. Ndi chikho choyamwa chomwe chimamangiriridwa ku tsinde la valve (mutu wake) ndipo chimagwiritsidwa ntchito kuti chizitembenuza chokha kuti chisindikize bwino pakati pa kufika kwake (gawo lokhudzana ndi mutu wa silinda) ndi nyumba yomwe ili pamutu wa silinda. Pali mitundu iwiri ya ndodo: makoswe a pamanja ndi makoswe omwe amatha kusintha pobowola kapena kompresa. Mitengo imachokera ku 5 mpaka 300 mayuro… Zidzakhala zachikale kwa ine, kungokhala ndikumverera bwino kwa kukana ndi tirigu panthawi ya mikangano.

Zowonadi, tiyenera kuwonjezera phala lodziwika bwino pakuwongolera. Izi zidzasinthira magawo awiri olumikizana, kuwachotsa ndikuchotsa nthawi zonse komanso masewera aliwonse. Choncho, chiopsezo chilichonse kutayikira. Opaleshoniyi ndi yofunika kwambiri ndipo pali mitundu iwiri ya phala lopera: coarse and fine. Kwa ine, tirigu wabwino adachita zodabwitsa. Timayika pang'ono pamwamba kuti "apukuta" ndikutembenuza, kutembenuzira mpaka simukumva kukana kwa valve, mpaka zonse zitachoka, ndikuwonetsa pamwamba pake. Zabwino, zadziwika.

Valve mchira kasupe kompresa ikugwira ntchito

Njira Zotsitsimutsa Ma valve

Bwererani ku garaja kuti mutenge nawo mbali ndi ma valve ena 15. Mwachiwonekere, kunena mophweka, 636 ili ndi ma valve 4 pa silinda (ma valve awiri olowera, 2 yotulutsa mpweya) choncho ma valve onse a 16 omwe amafunika kukonzanso. Eduard anandionetsa imodzi mwa izo, akumaona mmene zinthu zidzakhalire bwino, choncho ndinali ndi zinthu 14 zoti ndichite. Zinalonjeza kuti zidzakhala zotopetsa komanso zowopsa, sizinali choncho.

Kuchokera ku mantha oyambirira akale, ndimamva bwino. Kukonzanso kwawo kunali ntchito yosangalatsa. Zimakhudza mavavu a pachimake cha njinga. Pamafunika kulondola, kusamalidwa, manja otetezeka, ndi njira yodzidalira yomwe imasinthidwa mwachangu pamene chisangalalo chikukula.

Chotsani valavu iliyonse ndi valavu ya compressor ya masika

Valve mchira kasupe kompresa ikugwira ntchito

Kukonza ndikosavuta. Ndikuyika mutu wa silinda "pansi". Choncho, mavavu ali pa "mphasa" mbali ya workbench ndipo nthawi zonse anagwiridwa molimba ndi kukanikiza kasupe awo pa khoma la yamphamvu mutu.

Ndili ndi chonyamulira valavu chomwe chimangokhazikika ndikamangitsa chogwirira chake. Gawo lozungulira komanso lotsekeka, loyenda, limalumikizana ndi "chikho" chomwe chimakhala ndi ma crescents. Winayo amakhala mbali ina ya mutu wa silinda. Ndikalimbitsa kukumbatirana, amakankhira chikho (chikho chomwe chimathira makiyi) ndikumangirira kasupe wa valve. Izi zimatulutsa makiyi (omwe ndimawatchanso crescents) omwe nthawi zambiri amakhala ndi mchira wa valavu pamlingo wamagazi omwe amaperekedwa kuti awayike.

Za kusamalira ndi losavuta

Ndi mtundu wa muyeso wa mgodi womwe umagwiridwa ndi kukakamizidwa, akasupe mpaka mutakanikiza mphira kapena kapu.

Valavu "imagwa" mwachibadwa ndipo ndimayibwezeretsa mwa kukweza mutu wa silinda. Kuti ndisataye kachigawo kakang'ono, ndimamasula compressor ya masika. Iwo alinso akaidi. Angathenso kuchotsedwa kuti apulumuke m'tsogolo mosavuta. Chabwino, ngati, ndinapempha, ngakhale kuli kovuta kwambiri kuwanyenga pamene kuswa, tikhoza kuwagulanso, kuchokera ku 2 mpaka 3 euro ...

Kumanzere, mchira wa valavu unatulutsidwa, ndipo chisindikizo chake, kumanja, valavuyo inakanizidwa mu crescents ziwiri.

kupukuta valavu

Panthawiyi, valavu iliyonse ikangophwanyidwa ndikuchotsedwa m'thupi (chipinda chokongola bwanji, mulimonse!), Ndimayika mosamala mu drill chuck (waya kapena chingwe) ndikutembenuza mutu wanga! Carousel, yomwe imaphatikizidwa pamwambowu ndi chisel chamatabwa chakuthwa bwino. Chipangizo chopangira valavu chakunja chingagwiritsidwenso ntchito, koma ndinalibe yankho lamankhwala kapena chilichonse chogwira ntchito monga momwe ndikuchitira pano. Palibe mantha kuukira kapangidwe kake: ndi kolimba kuchokera kolimba. Kumbali ina, ndimakhala wosamala kwambiri ndi m'mphepete mwa nthiti: musawawukire, monga mpando (pansi). Mwachiwonekere sikophweka kujambula chithunzi ndi manja onse kuti mufotokoze mfundoyo, koma mumapeza lingaliro.

Ndimakonda kuyang'ana momwe ndimayika valavu yakumbuyo mu chuck. Zimatenga mphindi 5 mpaka 10 pa valavu iliyonse, kutengera momwe valavu ilili komanso njira zodzitetezera. Ndikuyamikira kupeza njira yozungulira yoyenera kuti musinthe liwiro loyenera kuti muthe kuchotsa masikelo ndi zotsalira. Ndimathaŵa kwenikweni, ndikuwongolera manja. Ndimayang'ana, ndimaphunzira mosamala, ndikuwona, mwachidule, ndimakonda!

Vavu imatsukidwa ndi kupukuta

Kusintha Zisindikizo za Valve Yamchira

Valavu ikangobwerera ku mawonekedwe ake oyambirira (wangwiro!), Ndi nthawi yoti mubwezeretsenso, ndikudalira Alex ndi ntchitoyi. Iye ali ndi udindo wochotsa zisindikizo za valve mchira ndikuzisintha. Amavala m'nyumba mwake popanda kuyikanso zonyezimira. Izi zimalola kuzungulira kwaulere kuzungulira mchira wake.

Miyendo ya valve

Tsopano muyenera kuyika kapu yoyamwa tsinde pamutu wa valavu ndikuyika bonati (pamunsi ndi gawo lopindika la mutu wa valavu) ndikuyesa pachifuwa ndi chala chanu.

Timaphimba ndi popping mtanda

Monga momwe dzinalo likusonyezera, udindo wake ndi kugwiritsa ntchito malo awiri okhudzana kuti agwirizane bwino ndikupanga chisindikizo cholimba. Kodi tikudziwa bwanji kuti zachitika?

Kusuntha kwamphamvu kumachitika (kusinthasintha kosinthika kuchokera kumanzere kupita kumanja), valavu ili m'malo mwake. Poyambirira, mumamva kupyola pansi pa ndodo ngati nkhanza.

Timagwira ntchito mu valve

Njere yomwe imasowa pamene malo akufanana ndi mtanda ukugwira ntchito. Uwu ndi mtundu wa kupukuta, kusanja pamwamba. Pamene valavu patinates, monga batala, kutembenuka kwatha. Kuti mukhale ndi mtima woyera, mukhoza kuyesa kamodzi pobwezera mtanda wina: njere zasowa.

Makoswe, woyamwa kumapeto kwa ndodo, ali m'malo kuti abwezeretse valavu

Kumbukirani kuti Alex, wophunzira makanika chaka choyamba pasukulu yokonza njinga zamoto ku Angouleme, ali patchuthi kunyumba. Mosamala, akhama, amaona ntchitoyo kukhala yofunika kwambiri. Kukhwima kovomerezeka kwa opaleshoni yotereyi, kofunika. Vavu yomwe imapindika, imachotsa kapena chinachake, ndipo injiniyo yafa. Kugwira ntchito limodzi kumathandiza kuti tizisangalala limodzi.

Bwerani, tiyeni tipite kwa mphindi 10-15 chithandizo ... ndi valavu! Ndipo pali 14… Ndipereka Alex, manja ake atha pakapita nthawi. Pang'onopang'ono, mothandizidwa ndi butting, lapping phala ndi elbow mafuta zidzachitika bwino. Tikuganiza kuti ndife a Cro Magnon omwe tikuyesera kuyatsa moto pamene tikutembenuza tsinde la tsinde m'manja mwathu pamene tikupita mmwamba ndi pansi kuti tiwonetsetse kuti imayikidwa bwino. Zimatenga nthawi ndi nthawi, koma kachiwiri, zochitazo zimakhala zokopa.

Kubwezeretsa kwa Crescent

Chifukwa chake, titha kuyikanso ma crescents m'malo mwake, ndipo izi sizikhala zophweka nthawi zonse: nthawi zambiri amapendekeka. Chophimba chaching'ono chingathandize kuwatsogolera ndikupangitsa zinthu kukhala zosavuta. Samalani kuti mubwezeretse zonse m'malo mwake: chisindikizo cha mchira wa valve chomwe chimalumphira, kapena mikwingwirima yomwe imapanga mbiya ndipo ndife oipa: idzatulutsa valavu mu chipinda choyaka moto, ndipo apo ... moni, kuwonongeka.

Mayeso a Cylinder Head Leakage Test

Ma valve onse atayikidwa ndi kudyetsedwa, zidzatsimikiziridwa kuti mutu wa silinda wokwezeka udzapanga malo otsekedwa kwathunthu komanso osapanikizika. Amapereka kuponderezedwa kwabwino, komanso kuyaka bwino komanso kutulutsa mpweya chifukwa cha kuphulika komwe kumapangidwa ndi spark plug. Kuti ndichite izi, nthawi ino ndikutembenuza mutu wa silinda ndi ma valve omwe akulozera kumwamba ndikutsanulira mafuta mu crucible. Ngati ndikuwona zikuyenda mbali inayo, pa benchi yogwirira ntchito kapena pansalu, pali vuto ndipo muyenera kuyang'ana valving yoyenera kapena kubwereza kupukuta kwautali ndikuyika ndi phala laukali, grit coarse kuthamanga, ndiye bwino. mbewu. Ngati izi sizikugwirabe ntchito, tiyenera kuganizira zosintha ma valve omwe akufunsidwa, kapena kukonzanso mutu wa silinda, kapena kusintha kapena ... kufuula kuwombera bwino.

Ngati palibe chomwe chikuchitika, ndiye kuti zonse zili bwino. Ndipo kwa ine zonse zili bwino. Kupambana pang'ono kuti musangalale ndi nthawi yomwe mumaphunzitsidwa zamakanika "zachikale" komanso zomwe adagawana ndi Alex. Kwa ine, ndithudi, izi ndi makaniko: kusinthanitsa.

Titha kukweza mutu wa silinda ndikugawa. Zipitilizidwa…
