Zomwe Zimayambitsa ndi Kukonza Njira Zakulephera kwa Cylinder Gasket

Injini ya silinda yamutu wa gasket kutenthedwa ndi kutayikira kwa makina oponderezedwa ndikolephera pafupipafupi. Pambuyo pakuwotchedwa kwa cylinder head gasket, momwe injiniyo imagwirira ntchito idzawonongeka kwambiri, ndipo sizingagwire ntchito, komanso imatha kuwononga mbali zina kapena magawo ena; panthawi yoponderezedwa ndi mphamvu ya injini, chisindikizo chapamwamba cha pistoni chiyenera kusungidwa. , sayenera kutayikira. Pamodzi ndi zizindikiro za yamphamvu mutu gasket kutopa ndi mpweya kutayikira mu dongosolo psinjika, kusanthula ndi kuweruza zimayambitsa zizindikiro kulephera, ndi kusonyeza ntchito njira kupewa kuchitika zolephera ndi bwino kuwathetsa.

Choyamba, Kulephera kugwira ntchito pambuyo poti silinda yamutu yawonongeka

Chifukwa cha malo osiyanasiyana a cylinder head gasket kuwotcha, zizindikiro za kulephera zimasiyananso:

1. Kuwomba ndi mpweya pakati pa masilindala awiri oyandikana

Pansi pamalingaliro osayatsa decompression, gwedezani crankshaft ndikuwona kuti kukakamiza kwa ma silinda awiriwo sikukwanira. Pamene injini ikuyamba, pali chodabwitsa cha utsi wakuda, kuthamanga kwa injini kumatsika kwambiri, ndipo mphamvu ndi yosakwanira.

2. Kutaya kwa mpweya wa mutu wa silinda

Mpweya wopanikizidwa kwambiri umathawira m'mabowo a silinda yamutu wa silinda kapena kutayikira pamwamba pa mutu wa silinda ndi thupi. Pakutuluka kwa mpweya pali thovu lachikasu lopepuka. Kutuluka kwa mpweya kumakhala koopsa, padzakhala phokoso la "peeping", ndipo nthawi zina kumatsagana ndi kutuluka kwa madzi kapena kutuluka kwa mafuta. Mukachotsa ndikuwunika, mutha kuwona ndege yofananira ndi mutu wa silinda ndi malo oyandikana nawo. Pali zodziwikiratu kuti ma depositi a kaboni m'mabowo a silinda pamutu.

3. Mu gawo la mafuta la mafuta a gasi

Mpweya wothamanga kwambiri umathawira munjira yamafuta opaka mafuta omwe amalumikizana pakati pa chipika cha injini ndi mutu wa silinda. Kutentha kwa mafuta mu poto yamafuta kumakhala kokwera nthawi zonse injini ikathamanga, kukhuthala kwamafuta kumakhala kocheperako, kupanikizika kumachepa, ndipo kuwonongeka kumathamanga.

4. Mpweya wothamanga kwambiri umalowa mu jekete lamadzi ozizira

Pamene injini yozizira madzi kutentha ndi otsika kuposa 50 ℃, kutsegula thanki madzi chivundikirocho, ndipo inu mukhoza kuwona kuti pali thovu zoonekeratu kukwera ndi akutuluka mu thanki madzi, ndipo nthawi yomweyo, kuchuluka kwa mpweya wotentha zimatulutsa kuchokera. pakamwa pa tanki la madzi. Pamene kutentha kwa injini kumawonjezeka pang'onopang'ono, Kutentha kochokera kukamwa kwa thanki yamadzi kumawonjezekanso. Pankhaniyi, ngati chitoliro chosefukira cha thanki yamadzi chatsekedwa, ndipo thanki yamadzi imadzazidwa ndi madzi ku chivundikirocho, chodabwitsa cha thovu lokwera chidzakhala chowonekera kwambiri, ndipo muzovuta kwambiri, chodabwitsa ngati kuwira chidzachitika.

5. Silinda ya injini ndi jekete lamadzi ozizira kapena njira yamafuta opaka mafuta amadutsa

Padzakhala thovu lamafuta achikasu-wakuda akuyandama pamwamba pamadzi ozizira mu thanki yamadzi, kapena padzakhala madzi mumafuta mu poto yamafuta.

Chachiwiri, Kusanthula zifukwa kuonongeka yamphamvu mutu gasket

1. Kutalikitsa kapena kumasuka kwa mabawuti amutu ndi mtedza

Chifukwa cha extrusion mapindikidwe olowa pamwamba ya yamphamvu mutu ndi injini thupi, psinjika mapindikidwe wa yamphamvu mutu gasket, mochulukira mwangozi chifukwa cha kuthamanga kwa mpweya mkulu-anzanu kwa yamphamvu mutu mabawuti ndi mtedza, silinda ma bolts akumutu samapindika mozama, ndipo kusafanana kwapang'onopang'ono kwa ulusi kumakanikizidwa. Kusalala ndi kutsekeka kwa ma bolt chifukwa cha torque yochulukirapo kumatha kupangitsa kuti ma cylinder head bolts ndi mtedza atalikitsidwe kapena kumasulidwa, zomwe zimapangitsa kuti pakhale kupanikizika kosakwanira pamagulu a mutu wa silinda ndi injini ya injini komanso kupanikizika kosagwirizana kulikonse, zomwe zimapangitsa kuti pakhale kuthamanga kwambiri. kutentha ndi kuthamanga kwa gasi kuchokera kumaloko. Gawo lapansi lopanikizika limatuluka ndikuwotcha cylinder head gasket.

2. Kusintha kwa olowa pamwamba pa mutu yamphamvu ndi injini thupi

Ngati malo awiri ophatikizana awonongeka, cylinder head gasket siyingatsimikizidwe kuti ikanizidwa mofanana, motero kuchititsa kuti mpweya utuluke ndikupangitsa kuti cylinder head gasket ipse, chomwenso ndi chifukwa chachikulu chowotcha mutu wa silinda.

3. Kuyikako sikukwaniritsa zofunikira zaumisiri

Pakuyika, olowa pamwamba pa silinda mutu gasket si woyera, mndandanda wa kumangitsa mabawuti ndi mtedza wa silinda mutu si yolakwika, makokedwe si lalikulu mokwanira kapena wosagwirizana, ndi kukula kwa kumtunda kwa nkhope ya silinda iliyonse. liner pamwamba pa ndege chapamwamba cha injini thupi sikokwanira kapena si wofanana, chifukwa mpweya kutayikira ndi kuyaka. mutu wa silinda gasket.

4. Kutentha kwa injini

Makina ozizira a injini sagwira ntchito bwino, nthawi yoperekera mafuta yatsala pang'ono kutha, ndipo kuchulukirachulukira kwanthawi yayitali kumapangitsa injini kutenthedwa, makamaka pagawo lomwe lili pakati pa mpando wa valavu yolowera ndi yotulutsa pamutu wa silinda ndi potuluka. gawo la chipinda cha vortex. Zotsatira zake, gasket yamutu wa cylinder imataya kukhazikika kwake koyambirira ndipo imakhala yolimba, ndipo pamapeto pake imayaka.

5. Ubwino wa silinda mutu gasket palokha si oyenerera

Monga makulidwe osagwirizana, pakamwa mopanda mpukutu, kusakwanira kokwanira, zinthu zosakwanira, pamwamba pake, ndi zina zambiri, kapena cylinder head gasket imawonongeka ndi kusamalidwa kosasamala ndi msonkhano, ndikosavuta kupangitsa kuti silinda yamutu iwotche.

Chachitatu, Njira zopewera cylinder head gasket kuti isawotchedwe ndikuwonongeka

1. Yang'anani mosamalitsa tsamba lankhondo la zigawo ziwiri za mutu wa silinda ndi thupi la injini musanayike.

2. Onani ngati kutalika kotuluka kwa nkhope yakumtunda kwa silinda iliyonse pa ndege yapamwamba ya injini ya injini ndikokwanira komanso kofanana.

3. Onani ngati mtundu wa cylinder head gasket uli woyenerera.

4. Pa nthawi yoyika, sungani mofanana mabokosi ndi mtedza ngati mukufunikira, ndikufika pa torque yomwe mwatchulidwa.

5. Mutatha kusintha gasket yatsopano ya silinda, injini itatha kugwira ntchito kwa maola 10 mpaka 15, yang'anani ndikumangitsa ma bolts a silinda ndi mtedza umodzi ndi umodzi molingana ndi dongosolo lodziwika ndi torque. Injini ikagwira ntchito kwa maola 240-250, kulimba kwa mabawuti ammutu ndi mtedza kuyenera kuyang'aniridwa kamodzi, ndikumangika pakapita nthawi ngati kutayikira.

6. Musanakhazikitse, gwiritsani ntchito phala lapadera la graphite kumbali zonse za gasket ya silinda. Makulidwe a zokutira ndi pakati pa 0.03 ndi 0.05 mm. sokoneza. Kupaka mafuta ochepa mbali zonse za silinda mutu gasket kungathenso kuonjezera kumangika pambuyo unsembe, koma sayenera ntchito kwa nthawi yaitali, apo ayi yamphamvu mutu gasket ndi olowa pamwamba adzakhala zolimba womangidwa ndi kuonongeka mosavuta pa nthawi. disassembly.

7. Mogwirizana ikani chingwe chopyapyala cha waya wa asibesitosi kapena onjezani pepala lopyapyala lamkuwa ndi makulidwe ochepera kapena ofanana ndi 0.2 mm m'malo omwe silinda yamutu wa gasket nthawi zambiri imawotcha kuti magawo opindika amangike mwamphamvu kuti ateteze mutu wa silinda. gasket kuti ipse. Kuwonongeka

Chidule:

Zigawo za cylinder head gasket pa injini nthawi zambiri zimagwira ntchito pansi pa kutentha kwambiri, kuthamanga kwambiri komanso kuyenda kothamanga kwambiri. Chifukwa chake, silinda yamutu wa gasket ndi magawo ofananira ndiosavuta kuwotcha ndikupangitsa kuvala kwamakina mwachangu.

Kuti injini ikhale yogwira ntchito bwino nthawi zonse ndikutalikitsa moyo wautumiki, iyenera kugwiritsidwa ntchito moyenera komanso mosamalitsa. Pamene pali zizindikiro zolephera, m'pofunika mwamsanga kupeza chifukwa cha kulephera ndi kuphunzira yankho. Cholakwikacho chidzachotsedwa pambuyo pa yankho.
