Kodi chotsukira cha unyolo chimayamba molakwika?

Ndi chinthu chofala kwambiri kuti chocheka cha unyolo ali ndi vuto loyambitsa kapena sangathe kuyambitsa panthawi yogwiritsa ntchito. Kodi mumathetsa bwanji vutoli? Ngati mukufuna Chocheka cha Unyolo Kuti muyambe bwino, muyenera kutsimikizira mfundo izi:

[Zofunika]

Kukanikiza: Kuti silinda ikhale ndi mphamvu yoyenera, sipayenera kukhala kutayika kwa kukanikiza mkati mwa silinda.

Dongosolo loyatsira: Pa nthawi yoyenera kuyatsira, dongosolo loyatsira liyenera kutulutsa mphamvu.

Makina amafuta ndi kabureta: Chosakaniza cha mpweya ndi mafuta chiyenera kuperekedwa pa chiŵerengero chabwino kwambiri chosakaniza.

Chifukwa chake, ngati chotsukira cha unyolo chikuvuta kuyamba kapena sichingathe kuyamba, tidzathetsa vutoli limodzi ndi limodzi malinga ndi zinthu zomwe zili pamwambapa:

1 Chongani Kupsinjika: Kuzindikira kumayamba kunja ndipo kumatha mkati

Mikhalidwe yakunja → mikhalidwe yomangirira → silinda → pisitoni → crankcase

Choyamba yang'anani ngati pulagi ya spark yakhazikika, kenako tembenuzani gudumu loyambira (kokani choyambira) ndi dzanja. Ikadutsa pakati pa dead (kokani pang'onopang'ono choyambira kangapo), imamva yovuta kwambiri (ingayerekezeredwe ndi makina atsopano), ndipo Pambuyo potembenuza pakati pa dead (makina atazungulira kangapo), gudumu loyambira limatha kuzungulira lokha kudzera mu ngodya yayikulu (lidzapitiriza kuzungulira popanda kukoka choyambira), kusonyeza kuti kukanikizako ndi kwabwinobwino. Ngati pistoni izungulira pakati pa dead mwachangu kapena mosavuta, zikutanthauza kuti mphamvu yokanikiza silinda siyokwanira. Vuto lili mu: vuto la mafuta a injini limayambitsa kuwonongeka kwa silinda kapena kukoka silinda; silinda block ndi crankcase gasket zikutuluka.

Mavuto a Circuit 2: Kuzindikira Kumayambira Pakutuluka Ndipo Kutha Pachipu cha ImportSpark → Chivundikiro cha chivundikiro cha spark → Chosinthira → Waya Wokwera, Waya Wotsika ndi Chosinthira → Cholumikizira Choyatsira → Choyimitsa Choyatsira → Choyimitsa Choyatsira

Ngati kupanikizika kuli bwino, palibe phokoso lophulika mu silinda (palibe phokoso) poyambitsa macheka a unyolo, ndipo mpweya wotuluka mu muffler ndi wonyowa komanso wonunkha mafuta, zomwe zikusonyeza kuti pali vuto mu dongosolo la ma circuit. Pakadali pano, pulagi ya spark iyenera kuchotsedwa (onani kusiyana kwa pulagi ya spark plug 0.6 ~ 0.7 mm), lumikizani pulagi ya spark ku waya wamagetsi amphamvu, ndi mbali ya pulagi ya spark ili pafupi kwambiri ndi gawo lachitsulo la thupi la makina, ndikukoka makina mwachangu kuti muwone ngati pali ma spark abuluu. Ngati sichoncho, choyamba onani ngati chivundikiro cha pulagi ya spark chawonongeka, kenako chotsani pulagi ya spark, gwiritsani ntchito mwachindunji mawaya amphamvu amphamvu kuti muwone gawo lachitsulo la thupi pafupifupi 3mm, kokani choyambira, ndikuwona ngati pali ma spark abuluu akudumpha pa waya wamagetsi amphamvu. Ngati sichoncho, zikutanthauza kuti pali vuto ndi phukusi lamphamvu kapena flywheel.

3. Yang'anani dongosolo la mafuta: kuyambira polowera mpaka kumapeto kwa malo otulukira mafuta

Chivundikiro cha thanki yamafuta → Mafuta → Valavu yotulutsa utsi → Fyuluta yamafuta → Chitoliro chamafuta → Kabureta → Chitoliro chopanikizika chopanda mphamvu

Ngati dongosolo la circuit ndi labwinobwino, ndi nthawi yoti muyang'ane dongosolo loperekera mafuta. Ngati palibe phokoso lophulika mu silinda poyambitsa, chitoliro chotulutsa utsi ndi chofooka, ndipo mpweya ndi wouma ndipo mulibe fungo la mafuta, mwina zimasonyeza kuti pali vuto ndi mafuta. Onani ngati pali mafuta okwanira mu thanki yamafuta, ngati fyuluta yamafuta yatsekedwa kwambiri, ngati chitoliro chamafuta chasweka ndipo chikutuluka, komanso ngati carburetor yatsekedwa. Ngati zonse izi zili bwino ndipo simungathe kuyambitsa, mutha kuchotsa spark plug, kutsanulira madontho angapo a mafuta mu dzenje la spark plug (osati kwambiri), kenako ikani spark plug ndikuyambitsa chain saw. Ngati iyamba ndikugwira ntchito kwakanthawi, zikutanthauza kuti carburetor yatsekedwa mkati. Mutha kusokoneza carburetor kuti muyeretse kapena kusintha.

41-Palibe chimodzi mwa zinthu zitatu zomwe zachitika

Ngati zonse zomwe zatchulidwa pamwambapa zili bwino, muyenera kuganizira ngati kutentha kwa malo oyambira kuli kotsika kwambiri.

Mwina chifukwa chakuti makinawo ndi ozizira kwambiri, mafuta sali osavuta kupanga atomu ndipo sikophweka kuyatsa. Nthawi yomweyo, ndikofunikiranso kuganizira ngati crankcase ili ndi kutseka koyipa chifukwa cha kuwonongeka kwa chisindikizo cha mafuta. Pamene kutentha kwa mlengalenga kuli kotsika, damper iyenera kutsekedwa pang'ono. Pamene kutentha kwa mlengalenga kuli kokwera, damper iyenera kutsegulidwa kwathunthu isanayambe.

5. Chiŵerengero cha mafuta a petulo chimayambitsa kulephera Ngati chiŵerengero cha mafuta a chain saw sichili bwino kapena pali mpweya wambiri mu muffler, izi zipangitsanso kuti chain saw ikhale yovuta kuyambitsa kapena kulephera kuyambitsa. Yeretsani pafupipafupi kuti muchotse fumbi pa muffler, fyuluta ya mpweya, ndi thupi. Kuchuluka kolakwika kapena khalidwe loipa la mafuta ndi injini kudzakhudzanso kuyambika kwa makina. Ayenera kukonzedwa ndikusankhidwa malinga ndi zofunikira m'buku la chain saw.

Njira ndi njira zoyambira

Njira ndi njira yogwiritsira ntchito chingwe chokokera choyambira komanso liwiro loyambira (momwe mumakokera choyambira mwachangu) zimakhudzanso kuyambika kwa chocheka cha unyolo.

Kodi ndiyenera kuchita chiyani ngati chotsukira unyolo chikuyamba bwino koma liwiro silingathe kufika kapena malo oimikapo pedal ya mafuta akuyamba? Chonde pitirizani kufufuza.

Mafuta:

1. Onetsetsani ngati fyuluta ya mpweya yatsekeka, yatsukidwa kapena yasinthidwa;
2. Mutu wa fyuluta yamafuta watsekeka, ingosinthani;
3. Kugwiritsa ntchito mafuta molakwika, gwiritsani ntchito mafuta oyenera;
4. Kusintha kwa carburetor sikuli bwino. Konzaninso singano yamafuta ndikuyisinthanso (tembenuzani singano yamafuta ya H ndi L mozungulira mpaka kumapeto, tembenuzani singano yamafuta ya H 1 ndi theka mpaka kutembenuka kawiri mozungulira mozungulira, ndikutembenuza singano yamafuta ya L 2 ndi 2 ndi theka mozungulira mozungulira. , ngati liwiro lalikulu silingafikike, tembenuzani singano yamafuta ya H mozungulira mozungulira 1/8 nthawi iliyonse; ngati liwiro losagwira ntchito ndi labwinobwino ndipo throttle yazimitsidwa, tembenuzani singano ya L mozungulira mozungulira 1/8 nthawi iliyonse);
5. Kabureta yatsekedwa, yatsukidwa kapena yasinthidwa.

Dongosolo lotulutsa utsi:

1. Chotsekeracho chatsekedwa ndi kaboni, chochotsa mpweya woipa kapena chotsani ndi moto
2. Chitseko chotulutsira mpweya cha silinda chatsekedwa ndi ma carbon deposits, ndipo chimachotsa ma carbon deposits

Dera:

Phukusi lamagetsi amphamvu lawonongeka mkati ndipo likufunika kusinthidwa.
