Ko chain saw inotanga zvisiri izvo here?

Chinhu chinowanzoitika kuti thecheni sawane dambudziko kutanga kana kusatangwa panguva yekushandisa. Unoita sei nedambudziko iri? Kana uchida kuti cheni yesaha itange zvakajairika, unofanirwa kuve nechokwadi chekuti mapoinzi anotevera:

[Zvakakosha zvemukati】

Kutsikirira: Kuti uchengetedze yakakwana cylinder pressure, hapafanirwe kuve nekurasikirwa kwekumanikidza mukati mecylinder.

Ignition system: Panguva yakakwana yekudzima, iyo iginition system inofanirwa kuburitsa simba rakasimba.

Fuel system uye carburetor: Musanganiswa wemhepo-mafuta unofanirwa kupihwa pachiyero chakakwana chekusanganisa.

Naizvozvo, kana ketani yesaha ichinetsa kutanga kana kusatanga, isu tichagadzirisa dambudziko rimwe nerimwe zvichienderana nepamusoro pezvinhu:

1 Tarisa Kudzvinyirira: Kuongororwa kunotanga kunze uye kunopera mukati

Mamiriro ekunze → kuomesa mamiriro → silinda → piston → crankcase

Kutanga tarisa kana spark plug yakasimbiswa, uye wozoshandura vhiri rekutangisa (dhonza chinotangira) neruoko. Kana ichipfuura nepakati pepamusoro akafa (zvishoma nezvishoma dhonza mutangi 1-2 kutendeuka), inonzwa zvakanyanya kushanda (inogona kufananidzwa nemuchina mutsva), uye Mushure mekutenderedza pamusoro penzvimbo yakafa (mushure mekunge muchina watenderera kakati), vhiri rekutanga rinogona kutenderedza otomatiki kuburikidza nekona yakakura (icharamba ichitenderera pasina kudhonza chinotangira), zvichiratidza kuti kudzvanya kwakajairika. Kana piston ikatenderera ichipfuura nepamusoro penzvimbo yakafa nekukurumidza kana nyore, zvinoreva kuti cylinder compression force haina kukwana. Dambudziko riri mu: dambudziko remafuta ejini rinokonzera kupfeka silinda kana cylinder kudhonza; iyo cylinder block uye crankcase gasket iri kubuda.

2 Matambudziko Edunhu: Kuongororwa Kunotanga Pakubuda uye Kunoperera paImportSpark plug → Spark plug cap → switch → high voltage, pasi waya uye chinja waya → coil yekubatidza → flywheel

Kana kudzvinyirirwa kuri kwakajairika, hapana ruzha runoputika mucylinder (hapana ruzha) paunotanga saha yeketani, uye gasi rinoburitswa kubva muffler rakanyorova uye kunhuwa kwepeturu, izvo zvinoratidza kuti pane chikanganiso muhurongwa hwedunhu. Panguva ino, spark plug inofanira kubviswa (tarisa spark plug gap 0.6 ~ 0.7 mm), batanidza spark plug kune yakakwirira-voltage waya, nedivi re spark plug padyo zvakanyanya nesimbi chikamu chemuviri wemashini. , uye nekukasira kudhonza muchina kuti uone kana pane sparks dzeblue. Kana zvisina kudaro, tanga watarisa kana spark plug cap yakanganiswa, wobva wabvisa spark plug, zvakananga shandisa high-voltage waya yekupedzisira kuona chikamu chesimbi chemuviri chinenge 3mm, dhonza chinotangira, uye ona kana paine sparks yebhuruu ichisvetuka. pamusoro petambo ye-high-voltage. Kana zvisina kudaro, zvinoreva kuti pane dambudziko ne-high-pressure package kana flywheel.

3. Tarisa iyo oiri sisitimu: kutanga kubva pakupinda uye kugumira pakubuda

Tangi remafuta chivharo → Mafuta → vharafu → Sefa yemafuta → Pombi yemafuta → Carburetor → Pombi inopinza isina simba

Kana iyo yedunhu system yakajairika, inguva yekutarisa mafuta ekupa system. Kana pasina kuputika mutsindo mu cylinder paunotanga, pombi yekupedza haina simba, uye gasi rakaoma uye harina kunhuhwirira kwepetroli, zvinowanzoratidza kuti kune dambudziko nemafuta. Tarisa kuti mutangi remafuta mune mafuta akakwana here, kana sefa yemafuta yakavharika zvakanyanya, kana pombi yemafuta yakatyoka uye ichidonha, uye kana carburetor yakavharwa. Kana macheki aya ese akanaka uye uchiri kutadza kutanga, unogona kubvisa spark plug, wodira madonhwe mashoma epeturu mugomba re spark plug (kwete yakawandisa), wozoisa spark plug wotanga saha. Kana ichigona kutanga uye kumhanya kwechinguva, zvinoreva kuti carburetor yakavharwa mukati. Iwe unogona disassemble iyo carburetor yekuchenesa kana kutsiva.

41-Hapana kana ye3 mamiriro

Kana zvese zvataurwa pamusoro zvakanaka, iwe unofanirwa kufunga kana tembiricha yenzvimbo yekutanga yakadzikira.

Pamwe nekuti muchina wacho unotonhora zvakanyanya, peturu haisi nyore kuisa atomize uye hazvisi nyore kutanga. Panguva imwecheteyo, zvinodikanwawo kufunga kuti crankcase ine kusavharika kwakashata nekuda kwekukuvara kwechisimbiso chemafuta. Kana iyo ambient tembiricha yakaderera, damper inofanira kuvharwa zvishoma zvishoma. Kana tembiricha ye ambient yakakwira, damper inofanira kuvhurwa zvizere isati yatanga.

5. Gasoline mafuta reshiyo inokonzera kukundikanaKana chiyero chemafuta checheni saw chisina kunaka kana paine yakawandisa kabhoni dhipoziti mumuffler, ichaitawo kuti cheni isaha inonetsa kutanga kana kutadza kutanga. Ichenese nguva nenguva kubvisa huruva kubva muffler, air filter, uye muviri. Iyo isiriyo giredhi kana yakashata mhando yepeturu neoiri yeinjini ichakanganisawo kutanga kwemuchina. Dzinofanirwa kugadzirwa uye kusarudzwa maererano nezvinodiwa muchetani saw manual.

Nzira dzekutanga uye maitiro

Mafambiro uye hunyanzvi hwetambo yekukweva yekutanga uye kumhanya kwekutanga (kuti unodhonza sei chinotangira) zvakare zvine chekuita nekutanga kwecheni saha.

Chii chandinofanira kuita kana cheni yesaha ichigona kutanga zvakajairika asi sipidhi isingasvikike kana pedhisi inotsika? Ndokumbirawo rambai muchiongorora

Mafuta:

1. Tarisa kana sefa yemhepo yakavharwa, yakachena kana kuitsiva;
2. Musoro wesefa yemafuta wakavharwa, ingoutsiva;
3. Kushandiswa kwemafuta zvisirizvo, shandisa mafuta chaiwo;
4. Iyo carburetor kugadzirisa haina kunaka. Gadzirisa tsono yemafuta uye uigadzirise zvakare (shandura H uye L tsono dzemafuta zvichidzika kusvika kumagumo, shandura tsono yeH mafuta 1 nehafu kusvika 2 inotendeuka inopesana newachi, uye shandura iyo L mafuta tsono 2 uye 2 nehafu inotendeuka inopesana newachi. . , kana kukurumidza kusingasvikike, shandura tsono yeH yeawa 1/8 nguva imwe neimwe kana kukurumidza kusina basa kwakajairika uye throttle yakadzimwa, shandura tsono yeL 1/8 nguva imwe neimwe;
5. Iyo carburetor yakavharwa, yakachena kana kuitsiva.

Exhaust system:

1. Iyo muffler yakavharwa nekabhoni, bvisa kabhoni deposit kana kushandisa moto kuibvisa
2. Iyo cylinder exhaust port yakavharwa nekabhoni deposits, bvisa kabhoni deposits

Denderedzwa

Iyo yepamusoro-voltage package yakakuvadzwa mukati uye inoda kutsiviwa.
