Saha reChain rine simba guru re 87cc 4.2KW re 288 870

Chero chishandiso chemubindu chagara chichishandiswa kwenguva yakareba chichasangana nematambudziko makuru kana madiki. Kana zvikanganiso zvingabviswa nekukurumidza zvine chekuita nekuwedzera hupenyu hwazvo hwekushanda uye kuchengetedza kushanda zvakanaka. Semuenzaniso, kana usinganzwisise chero chinhu uye kubvunza nyanzvi pese panoitika dambudziko, rinogona kukunetsa zvakanyanya. Zvisinei, kana uchinzwisisa zvikanganiso zvakajairika nezvemasaha emubindu, unogona kugadzirisa zvikanganiso zviri nyore nyore.

Dambudziko rekutanga chitonhodzo chechainsaw

Kana chainsaw yatanga, injini inongoita ruzha rushoma pasina chinhu chinogara chichibatidza. Kunyangwe mushure mekutangidza kakawanda, inoramba yakadaro. Zviri pachena kuti izvi hazvisi dambudziko rekumanikidzwa kwe cylinder shoma kana kubuda kwemvura mu crankcase, uye harisi dambudziko rekukuvadzwa kwema spark plugs newaya dzine voltage yepamusoro dze ignition system, kana simba remagineti risina kukwana re magneto. Izvi zvinokonzerwa nekumanikidzwa kusina kukwana, kubuda kwemvura mu crankcase, kubuda kwe spark plugs newaya dzine voltage yepamusoro, kubviswa kwemagnetization yesimbi yemagnetic zvachose, uye simba remagineti risina kukwana, zvichiita kuti injini isakwanise kuputika. Kana dambudziko riri mu ignition system, kana iri injini ine contact magneto ignition, dambudziko rinonyanya kukonzerwa ne loose contact points, kutsva, mafuta matema, uye kuunganidzwa kwe oxide layers; Inogonawo kukonzerwa nekutyoka kwe flywheel half moon key nechitubu che contact rocker arm, pamwe nekusunungurwa kwe movable contact rocker arm. Kana iri non-contact magneto, yakawanda yacho inokonzerwa nekusabatana zvakanaka pa coil connector.

Kana kukanganisa kukaitika musystem yekupa mafuta, kunonyanya kukonzerwa nehunyoro mumafuta, mhepo iri mupombi yemafuta, uye mafuta akawanda kana akapfuma mumafuta akasanganiswa, izvo zvinogona kukonzera kuti injini irambe ichibvira moto kana injini ichitanga kutonhora. Nekuti simba remvura rakakura kupfuura remafuta, rinogara pasi petangi yemafuta. Kana injini yatanga, mafuta ari mucarburetor anogona kungopihwa chete kuti atange kutsva kwenguva pfupi uye kuputika. Kana mvura iyi iri mutangi yemafuta ikapinda mucarburetor kana pombi yemafuta, inodzima mafuta akajairwa, uye injini inomira kuputika pakarepo. Pamusoro pezvo, mafuta akawanda ekuzora mumafuta anokanganisa kukurumidza kweatomization yemafuta, zvichiita kuti zviomere musanganiswa kuti ubatidze, dzimwe nguva uchibatidza, uye urege kuramba. Mafuta ari mumusanganiswa wacho akawandisa, uye kunyangwe akakwanisa kubatidzwa nespark ine simba mushure mekupinda mu cylinder, anodonha nekukurumidza nekuda kwekuwanda kwemafuta (ndiko kuti, insulation yakakomberedza danda repakati re spark plug uye pakati pemapango epadivi zvese zvinozadzwa nemafuta akawandisa). Kana paine mafuta akawandisa akasanganiswa kana mafuta akawandisa akasanganiswa mumafuta akasanganiswa, gasi re exhaust rinoburitswa ne exhaust muffler panguva yekuputika rinofanira kunge riri utsi hutema hwakakora.

Kuvharwa kwechainsaw pakupisa kwakanyanya

Chiratidzo chinowanzoitika ndechekuti mushure mekushanda kwenguva yakati, injini inongoerekana yamira uye haigone kudhonzwa. Zvinotora nguva kuti moto utange, uye mushure mekushanda kwenguva yakati, mamiriro ezvinhu aya anoitika zvakare, uye anowanzoitika kana kuchipisa. Izvi zvataurwa pamusoro apa mamiriro ezvinhu akajairika apo chainsaw inomira pakupisa kwakanyanya. Tinofanira kuitei mumamiriro ezvinhu aya? Kutanga, tinofanira kuziva zvikonzero. Zvikonzero nemhinduro zvinowanzoonekwa ndeizvi:

1. Matambudziko ekufema

Zvikurukuru imhaka yekusafema zvakanaka kwe crankcase nezvikamu zvepurasitiki, izvo zvinokonzeresa kusafema zvakanaka kwezvikamu zve carburetor uye zvinokonzera kudzikamiswa kwekupisa kwakanyanya.

Mhinduro: Kufefetera. Kana chifukidziro chemhepo chikawedzerwa pa magnetic flywheel kana kuti nzira iri pakati pe magnetic flywheel ne carburetor iri pa crankcase ikavhurwa, mwero wekufema unogona kuwedzerwa, kana kuti kit yebhokisi remhepo rine mhepo iri nani uye chifukidziro chemhepo chinogona kutsiviwa.

2. Kubuda kwemhepo kusina kunaka kwemuffler kunokonzera kupisa kwakanyanya

Mhinduro: Geza chivharo chemushonga kana kuchitsiva nechivharo chine gomba guru rekubuda naro. (Cherechedza: kuva nemaburi akawanda hazvirevi kuti zvinorongwa nekukurumidza. Pamusika, maburi makuru ane maburi maviri ari nani pane maburi madiki matatu ane maburi.).

3. Kudzivirira kupisa kwakaderera kwemakabhureta

Mhinduro: Wedzera mapedhi ekudzivirira kupisa, bvisa mhepo, chenesa kana kutsiva macarburetor.

4. Pakeji yekoiri/yemagetsi akakwira haipindi kupisa kwakanyanya

Mhinduro: Tsiva zvakananga.

5. Zvikamu zvitatu zvesirinda

Chimwe chezvinhu zvitatu, sirinda, piston, uye rin'i yepiston, chakagadzirwa nezvinhu zvisina kunaka.

Mhinduro: Tsiva silinda yeruoko rwechainsaw.

6. Zvivharo zvemafuta nemapombi emhepo ane simba (mapaipi egasi akaenzana) hazvigoni kudzikamiswa nekupisa kwakanyanya

Chisimbiso chemafuta nepaipi yekumanikidza isina simba (paipi yegesi inoenzana) hazvigoni kudzikamiswa nekupisa kwakanyanya, zvichikonzera kubuda kwemhepo kana tembiricha yakakwira.

Mhinduro: Tsiva chisimbiso chemafuta chemhando yepamusoro uye pombi yekumanikidza isina simba (balance air pipe).
