Kusintha kwa valavu VAZ 2114

Masiku ano, galimoto iliyonse yamakono, kupatulapo magetsi, ili ndi injini yoyaka mkati yomwe imakhala ndi makina ogawa gasi. Magawo ambiri amadalira ntchito yoyenera ya dongosolo lino. Ndipo izi zikuphatikiza kugwiritsa ntchito mafuta, kuthamanga kwa injini, magwiridwe antchito a chilengedwe ndi zizindikiro zina zofunika. Kugwira ntchito moyenera kwa makina ogawa gasi kumatsimikiziridwa ndi kusintha koyenera kwa mipata pakati pa valve ndi pusher yake.

Ngati kusiyana kuli kwakukulu kwambiri, camshaft cam inagunda kwambiri mbale, ndipo zonsezi zidzabweretsa kuwonongeka kwakukulu kwa zigawo za injini ndi makina. Komanso, valavu sidzatsegula mokwanira pakufunika, motero imalepheretsa kuyenda kwa mpweya kapena mpweya wosakaniza, koma malingana ndi mtundu wa valve. Inlet - imayang'anira kupereka kwamafuta, kutulutsa - kwa mpweya wotulutsa mpweya womwe umatumizidwa kumagetsi ambiri.

Mfundo yogwiritsira ntchito makina a valve

M'malo mwake, ngati valavu yatsekedwa mwamphamvu, kuwonongeka kwa makina kumagulu a injini kudzakhala kochepa ngati kusiyana kwake kuli kwakukulu. Koma ntchito ya injini yokha idzakhala yoipa kwambiri. Ndi chifukwa cha ntchito yolondola ya injini m'pofunika kusintha mosamala mavavu pa galimoto VAZ. Njirayi ikuchitika m'njira zingapo. Choyamba ndi chakuti chopondera chimayenda pansi pa chikoka cha mtedza pa tsinde. Chachiwiri ndikusankha ma spacers a makulidwe omwe mukufuna. Chachitatu ndi chodziwikiratu, choyendetsedwa ndi kuthamanga kwamafuta a injini pama hydraulic lifters.

Ife kuvumbula kusiyana pa Vaz 2114

Kwa ife, pa galimoto ya Vaz 2114, ndondomekoyi ikuchitika mwa njira yachiwiri, pogwiritsa ntchito gaskets ndi chida chapadera.

Choyamba, muyenera kumvetsa kuti kusintha olondola pa Vaz 2114 akhoza kuchitidwa pa kutentha yozungulira 20 digiri Celsius, pamene zitsulo pa mpumulo ndipo si pansi pa kukula matenthedwe monga injini yotentha.

Kachiwiri, pa galimoto iliyonse pali tebulo la kukula kwa chilolezo chokhala ndi makamera a camshaft.

Kwa chitsanzo chakhumi ndi chinayi, miyeso yotsatirayi imagwiritsidwa ntchito:

• Kwa mavavu olowera: 0,2 mm ndi cholakwika chowerengera 0,05 mm;
• Kwa ma valve otulutsa mpweya: 0,35 mm ndi zolakwika zowerengera za 0,05 mm.

Musanayambe kusintha, kuziziritsa chipinda cha injini, mutha kugwiritsa ntchito fan wamba. Pambuyo pake, timachotsa chivundikiro cha valve, mapaipi, zikhomo zotsekera, mbali yotetezera lamba wa nthawi. Mukamasula nati yomwe imakhala ndi chingwe chonyamulira chothamangitsira, chotsani mosamala. Chotsani gulu la nyumba zosefera mpweya kuti zigwire ntchito mosavuta. Musanagwetse, onetsetsani kuti mwayika ma wedges pansi pa mawilo ndikuyatsa zida zopanda ndale. Mabuleki oimika magalimoto ayeneranso kuyatsidwa.

Chida chofunikira

Zida zofunika pa ntchito:

1. 1. Soketi ndi ma wrenches otseguka;
2. 2. Chipangizo chochepetsera mbale za valve - zimawononga pang'ono kuposa ma ruble zana;
3. 3. A gulu la kafukufuku wapadera kuyeza chilolezo mu limagwirira;
4. 4. Micrometer kudziwa makulidwe a gasket;
5. 5. Kusintha ma washers: Makulidwe kuchokera ku 3 mpaka 4,5 mm. Amaperekedwa kumsika muzowonjezera za 0,05 mm. Ndiko kuti, mungapeze ma washer ndi kukula kwa 3,05mm, 3,1mm, ndi zina zotero mpaka 4,5mm. (Chimbalecho chimawononga pafupifupi ma ruble makumi awiri).

Njira zosintha

Yang'anani ngati zizindikiro pazitsulo za nthawi ndi pa chivundikiro chamutu cha silinda cha machesi a VAZ 2115. Zizindikiro zomwezo ziyenera kufanana ndi pulley ya crankshaft ndi chivundikiro cha pampu ya mafuta. Kenako, masulani ma spark plugs kuti muchepetse kuthamanga kwa silinda.

Pansi pa chivundikiro cha valve panthawi yokonzanso, ikani gasket yatsopano yokhala ndi sealant mu grooves.

Dongosolo la mavavu VAZ 2114

Mukakonza, samalani kuti valavu iti yomwe imalowera komanso yomwe imatuluka, dongosololi lili motere:

5 - kumasulidwa ndi 2 - kulowetsa; 8 - zotuluka ndi 6 - zolowetsa; 4 ndiye zotulutsa ndipo 7 ndiye zolowetsa.

Kuchokera ku pulley ya camshaft, timayesa mipata pakati pa pusher ndi camshaft. M'malo omwe kusiyana kuli kwabwinobwino, zonse sizisintha. Pamalo omwe kafukufuku wa kukula koyenera amalowetsedwa mosavuta mu groove, timakanikiza mbale ndi chipangizo chotsitsa pusher, ndikuyika mbendera kuti tikonze pusher. Kenako, pogwiritsa ntchito ma tweezers apadera, timatulutsa chowotcha chosinthira ndikuyang'ana chizindikiro chake. Ngati ndi kotheka, yesani makulidwe ake ndi micrometer. Kenaka, timasankha chotsuka chowonjezera, ndikuchiyika pamalo ake ndipo choyamba fufuzani kusiyana ndi kafukufuku wofunidwa.

Ma Valve clearance

Ngati sichikukwanira, ndiye kuti timatenga chubu chochepa kwambiri, ndi zina zotero mpaka chubu chikwanira. Kuchokera kusiyana pakati pa kukula kwadzina ndi kukula kwa kafukufuku, zomwe zimagwirizana mosavuta, timawerengera makulidwe ofunikira a bar. Timabwereza ndondomekoyi mpaka kafukufukuyo akuyamba kulowetsedwa ndi kutsika pang'ono.

Ngati palibe ma probes oyenerera, valavuyo imatambasula! Malinga ndi ntchito yapitayi, chotsani chowotcha chosinthira ndikusintha kukhala chaching'ono.
