Kodi unyolo wocheka umayamba mwachilendo?

Ndi chodabwitsa chodziwika kutiunyolo machekaakuvutika kuyamba kapena sangayambike panthawi yogwiritsira ntchito. Kodi mumathana ndi vutoli bwanji? Ngati mukufuna kuti tcheni chiziyamba bwino, muyenera kutsimikizira mfundo izi:

[Zofunikira]

Kuponderezana: Kuti mukhalebe ndi mphamvu yokwanira ya silinda, pasakhale kutaya kwa kuponderezana mkati mwa silinda.

Dongosolo loyatsira: Pa nthawi yoyenera kuyatsa, choyatsira chiyenera kutulutsa mphamvu yamphamvu.

Makina amafuta ndi carburetor: Kusakaniza kwamafuta a mpweya kuyenera kuperekedwa pamlingo wosakanikirana bwino.

Chifukwa chake, machesi akamavuta kuyamba kapena osayamba, tidzathetsa vutolo limodzi ndi limodzi molingana ndi izi:

1 Chongani Kupanikizika: Kuzindikira kumayambira kunja ndikutha mkati

Zinthu zakunja → zomangitsa → silinda → pistoni → crankcase

Choyamba fufuzani ngati pulagi ya spark yakhazikika, ndiyeno tembenuzani gudumu loyambira (kokani choyambira) ndi dzanja. Ikadutsa pamwamba akufa pakati (pang'onopang'ono kukoka sitata 1-2 kutembenuka), amamva zolemetsa kwambiri (angayerekezedwe ndi makina atsopano), ndipo Pambuyo kutembenukira pamwamba akufa pakati (pambuyo makina atembenuza kangapo), gudumu loyambira limatha kusuntha mozungulira mokulirapo (lidzapitilirabe kusinthasintha popanda kukoka koyambira), kuwonetsa kuti kuponderezana ndikwachilendo. Ngati pisitoni imazungulira pamwamba pa malo akufa mofulumira kapena mosavuta, zikutanthauza kuti mphamvu ya cylinder compression sikwanira. Vuto liri mu: vuto la mafuta a injini limapangitsa kuvala kwa silinda kapena kukoka kwa silinda; cylinder block ndi crankcase gasket ikutha.

2 Mavuto Ozungulira: Kuzindikira Kumayambira Pakutuluka Ndi Kutha pa Pulagi ya ImportSpark → kapu ya pulagi ya spark → switch → magetsi okwera, waya pansi ndikusintha waya → koyilo yoyatsira → flywheel

Ngati psinjika ndi yachibadwa, palibe phokoso kuphulika mu yamphamvu (palibe phokoso) poyambitsa unyolo macheka, ndi mpweya kutulutsidwa muffler ndi lonyowa ndi fungo la mafuta, zomwe zimasonyeza kuti pali vuto dongosolo dera. Panthawiyi, pulagi ya spark iyenera kuchotsedwa (onani kusiyana kwa spark plug 0.6 ~ 0.7 mm), kulumikiza pulagi ku waya wothamanga kwambiri, ndi mbali ya spark plug pafupi kwambiri ndi gawo lachitsulo la makina. , ndipo mwamsanga kukoka makina kuti awone ngati pali buluu sparks. Ngati sichoncho, yang'anani kaye ngati kapu ya spark plug yawonongeka, ndiye chotsani pulagi, gwiritsani ntchito ma waya okwera kwambiri kuti muwone mbali yachitsulo ya thupi pafupifupi 3mm, kukoka choyambira, ndikuwona ngati pali zipsera zabuluu zikudumpha. pamwamba pa waya wothamanga kwambiri. Ngati sichoncho, zikutanthauza kuti pali vuto ndi phukusi lapamwamba kwambiri kapena flywheel.

3. Yang'anani dongosolo lamafuta: kuyambira polowera mpaka kumapeto

Chophimba cha tanki yamafuta → Mafuta → Vavu yotulutsa mpweya → Fyuluta yamafuta → Chitoliro chamafuta → Carburetor → chitoliro choletsa kukakamiza

Ngati dongosolo la dera ndi lachilendo, ndi nthawi yoti muwone momwe mafuta amaperekera. Ngati palibe phokoso la kuphulika mu silinda poyambira, chitoliro chotulutsa mpweya chimakhala chofooka, ndipo mpweya ndi wouma ndipo ulibe fungo la mafuta, nthawi zambiri zimasonyeza kuti pali vuto ndi mafuta. Onani ngati mu thanki yamafuta muli mafuta okwanira, ngati fyuluta yamafuta yatsekedwa kwambiri, ngati chitoliro chamafuta chathyoka ndi kutuluka, komanso ngati kabureta watsekedwa. Ngati macheke awa onse ali abwino ndipo simungayambebe, mutha kuchotsa pulagi, kutsanulira madontho ochepa a petulo mu dzenje la spark plug (osati mochulukira), ndiye ikani pulagi ndikuyambitsa macheka. Ngati ingayambe ndikuthamanga kwa kanthawi, zikutanthauza kuti carburetor yatsekedwa mkati. Mutha disassemble carburetor kuti muyeretse kapena kusintha.

41-Palibe zochitika zitatuzi

Ngati zonse zomwe zatchulidwazi zili bwino, muyenera kuganizira ngati kutentha kwa chilengedwe ndikotsika kwambiri.

Mwinamwake chifukwa chakuti makinawo ndi ozizira kwambiri, mafuta a petulo si ophweka kuti atomize ndipo sikophweka kuyambitsa. Panthawi imodzimodziyo, m'pofunikanso kuganizira ngati crankcase ili ndi kusindikizidwa bwino chifukwa cha kuwonongeka kwa chisindikizo cha mafuta. Kutentha kozungulirako kukakhala kocheperako, damper iyenera kutsekedwa pang'ono. Kutentha kozungulira kukakhala kokwera, damper iyenera kutsegulidwa kwathunthu isanayambe.

5. Chiŵerengero cha mafuta a petulo chimayambitsa kulepheraNgati chiŵerengero cha mafuta a tcheni sichili bwino kapena pali carbon deposit yochuluka mu muffler, zidzachititsanso kuti tcheni chikhale chovuta kuyamba kapena kulephera kuyamba. Iyeretseni pafupipafupi kuti muchotse fumbi la muffler, mpweya, ndi thupi. Gawo lolakwika kapena kutsika kwamafuta amafuta ndi injini yamafuta kukhudzanso kuyambitsa kwa makina. Ayenera kukonzedwa ndikusankhidwa molingana ndi zofunikira mu chain saw manual.

Njira zoyambira ndi njira

Mayendedwe ndi njira ya chingwe choyambira kukoka ndi liwiro loyambira (momwe mumakokera choyambira) zimathandizanso pakuyamba kwa unyolo.

Kodi ndingatani ngati tcheni chocheka chingayambe bwino koma liwiro silingafike kapena malo okwera gasi? Chonde pitilizani kufufuza

Mafuta:

1. Yang'anani ngati fyuluta ya mpweya yatsekeka, iyeretseni kapena isinthe;
2. Mutu wa fyuluta wamafuta watsekedwa, ingolowetsani;
3. Kugwiritsa ntchito mafuta molakwika, gwiritsani ntchito mafuta oyenera;
4. Kusintha kwa carburetor ndikolakwika. Bwezeretsani singano yamafuta ndikuyisinthanso (sinthani singano za H ndi L molunjika mpaka kumapeto, tembenuzirani singano ya H mafuta 1 ndi theka mpaka 2 kutembenukira kunjira, ndikutembenuzira singano ya L mafuta 2 ndi 2 ndi theka kutembenukira kunjira ., ngati liwiro lapamwamba silingafikidwe, tembenuzirani singano ya H molunjika 1/8 nthawi iliyonse ngati liwiro lopanda ntchito ndi lachilendo ndipo phokoso lazimitsidwa, tembenuzirani singano ya L 1/8 nthawi iliyonse;
5. Carburetor imatsekedwa, kuyeretsa kapena kuyisintha.

Exhaust System:

1. Chophimbacho chimakutidwa ndi kaboni, chotsani kaboni kapena gwiritsani ntchito moto kuti muchotse
2. Doko lotulutsa mpweya wa cylinder limakutidwa ndi ma depositi a kaboni, chotsani ma depositi a kaboni

Dera:

Phukusi lapamwamba kwambiri lawonongeka mkati ndipo likufunika kusinthidwa.
