Ngaba isarha yetsheyini iqala ngokungaqhelekanga?

Yinto eqhelekileyo ukuba iisarha yekhonkcoinobunzima bokuqalisa okanye ayinakuqalwa ngexesha lokusetyenziswa. Uhlangabezana njani nale ngxaki? Ukuba ufuna isarha yekhonkco iqale ngokwesiqhelo, kufuneka uqinisekise ezi ngongoma zilandelayo:

[Umxholo obalulekileyo】

Ukunyanzeliswa: Ukugcina uxinzelelo lwe-cylinder olufanelekileyo, akufanele kubekho ilahleko yoxinzelelo ngaphakathi kwe-cylinder.

Inkqubo yokutshisa: Ngexesha elifanelekileyo lokutshisa, inkqubo yokutshisa kufuneka ivelise intlantsi eyomeleleyo.

I-fuel system kunye ne-carburetor: Umxube we-fuel-air kufuneka unikezwe ngomlinganiselo ofanelekileyo wokuxuba.

Ke ngoko, xa i-chain saw inobunzima bokuqalisa okanye ayikwazi ukuqala, siya kuyilungisa ingxaki nganye nganye ngokwezi zinto zingasentla:

I-1 Hlola i-Compression: Ukuxilongwa kuqala ngaphandle kwaye kuphelela ngaphakathi

Iimeko zangaphandle → iimeko eziqiniswayo → isilinda → ipiston → crankcase

Okokuqala jonga ukuba i-spark plug iqinisiwe, uze ujike ivili lokuqalisa (tsala isiqalisi) ngesandla. Xa idlula kwiziko eliphezulu ofileyo (tsala kancinane umqalisi 1-2 ujika), uziva enzima ngakumbi (inokuthelekiswa nomatshini omtsha), yaye Emva kokujika phezu iziko top ofileyo (emva kokuba umatshini ujikeleza amaxesha ambalwa), ivili lokuqalisa liyakwazi ukujikeleza ngokuzenzekelayo nge-angle enkulu (iya kuqhubeka ukujikeleza ngaphandle kokutsala umqalisi), ebonisa ukuba ukunyanzeliswa kuqhelekileyo. Ukuba i-piston ijikeleza ngaphaya kweziko eliphezulu elifileyo ngokukhawuleza okanye ngokulula, oko kuthetha ukuba i-cylinder compression force akwanelanga. Ingxaki ilele: Ingxaki ye-oyile ye-injini ibangela ukuguga kwe-cylinder okanye i-cylinder pull; ibhlokhi yesilinda kunye ne-crankcase gasket iyavuza.

Iingxaki ezi-2 zeSekethe: Uxilongo luqala ekuPhumeni kwaye luphele kwiplagi ye-ImportSpark → ispark plug cap → switsha → amandla ombane aphezulu, ucingo lomhlaba kunye nocingo lokutshintsha → ikhoyili yokulayita → iflywheel

Ukuba ukunyanzeliswa kuqhelekileyo, akukho sandi esiqhumayo kwi-cylinder (akukho sandi) xa uqala i-saw chain, kwaye igesi ekhutshwe kwi-muffler imanzi kwaye ivumba lepetroli, ebonisa ukuba kukho impazamo kwinkqubo yesiphaluka. Ngeli xesha, i-spark plug kufuneka isuswe (jonga i-spark plug gap 0.6 ~ 0.7 mm), qhagamshela i-spark plug kwi-high-voltage wire, kunye necala le-spark plug kufuphi kakhulu nenxalenye yentsimbi yomzimba womatshini. , kwaye ngokukhawuleza utsale umatshini ukuze ubone ukuba kukho iintlantsi eziluhlaza. Ukuba akunjalo, jonga kuqala ukuba i-spark plug cap yonakele, emva koko susa i-spark plug, sebenzisa ngokuthe ngqo isiphelo socingo oluphezulu-voltage ukubona inxalenye yesinyithi yomzimba malunga ne-3mm, tsala i-starter, kwaye ubone ukuba kukho iintlantsi eziluhlaza ezixhumaxhuma. phezu kocingo olunombane ophezulu. Ukuba akunjalo, kuthetha ukuba kukho ingxaki ngephakheji yoxinzelelo oluphezulu okanye i-flywheel.

3. Jonga inkqubo yeoli: ukuqala kwi-inlet kunye nokuphela kwindawo yokuphuma

Umnqwazi wetanki yesibaso → iFuel → ivalve yokukhupha → isihluzi samafutha → umbhobho wamafutha → Ikhabhureyitha → Umbhobho woxinzelelo ongeyo.

Ukuba inkqubo yesekethe iqhelekile, lixesha lokujonga inkqubo yokubonelela ngamafutha. Ukuba akukho msindo wokuqhuma kwi-cylinder xa uqala, umbhobho wokukhupha ubuthathaka, kwaye igesi yomile kwaye ayinayo iphunga le-petroli, mhlawumbi ibonisa ukuba kukho ingxaki yokunikezelwa kwamafutha. Khangela ukuba kukho amafutha awoneleyo kwitanki yamafutha, ukuba isihluzo sepetroli sivaleke ngokumandla na, ukuba umbhobho wamafutha wophukile kwaye uyavuza, nokuba i-carburetor ivalekile. Ukuba ezi zitsheki zilungile kwaye awukwazi ukuqalisa, ungasusa i-spark plug, ugalele amathontsi ambalwa epetroli kumngxuma we-spark plug (awuninzi kakhulu), uze ufake i-spark plug kwaye uqalise isarha yekhonkco. Ukuba inokuqala kwaye iqhube ixesha elithile, ithetha ukuba i-carburetor ivalekile ngaphakathi. Unako ukukhupha i-carburetor yokucoca okanye ukutshintshwa.

41-Akukho nanye yeemeko ezi-3

Ukuba yonke into ekhankanywe ngasentla ilungile, kuya kufuneka uqwalasele ukuba ubushushu bendawo yokuqalisa buphantsi kakhulu.

Mhlawumbi ngenxa yokuba umatshini ubanda kakhulu, i-petroli ayilula ukwenza i-atomize kwaye akukho lula ukuyiqalisa. Kwangaxeshanye, kuyafuneka ukuba kuqwalaselwe ukuba ingaba i-crankcase ayinakutywinwa kakuhle ngenxa yomonakalo wokutywinwa kweoyile. Xa ubushushu be-ambient buphantsi, i-damper kufuneka ivalwe encinci encinci. Xa ubushushu be-ambient buphezulu, i-damper kufuneka ivulwe ngokupheleleyo ngaphambi kokuba iqale.

5. Umlinganiselo weoyile yepetroli ubangela ukusilelaUkuba umlinganiselo wepetroli wesarha yekhonkco awulungile okanye kukho idiphozithi yekhabhoni eninzi kakhulu kwi-muffler, kuya kubangela ukuba ikhonkco libe nzima ukuqala okanye lingaphumeleli ukuqalisa. Yicoce rhoqo ukususa uthuli kwi-muffler, isihluzo somoya, kunye nomzimba. Ibakala elingalunganga okanye umgangatho ombi wepetroli kunye ne-oyile ye-injini kuya kuchaphazela ukuqala komatshini. Kufuneka ziqwalaselwe kwaye zikhethwe ngokweemfuno kwi-chain saw manual.

Iindlela zokuqalisa kunye nobuchule

Isalathiso kunye nobuchule bentambo yokutsala yokuqalisa kunye nesantya sokuqala (ukukhawuleza utsale isiqalisi) nako kunempembelelo ekuqaliseni kwesarha yekhonkco.

Kufuneka ndenze ntoni ukuba isarha yetsheyini inokuqalisa ngesiqhelo kodwa isantya asifikeleliyo okanye izitali zerhasi?Nceda uqhubeke uphande

Isibaso:

1. Jonga ukuba isihluzo somoya sivalekile, sicoce okanye sitshintshe;
2. Intloko yokucoca amafutha ivalekile, yibuyisele nje;
3. Ukusetyenziswa kakubi kwamafutha, sebenzisa isibaso esichanekileyo;
4. Uhlengahlengiso lwe-carburetor alulunganga. Seta kwakhona inaliti yeoli kwaye uyilungise kwakhona (jika iinaliti zeoli ze-H kunye ne-L ngasekunene ukuya ekupheleni, jika inaliti yeoli ye-H i-1 kunye nesiqingatha ukuya kwi-2 ijika i-counterclockwise, kwaye ujike inaliti yeoli ye-L 2 kunye ne-2 kunye nesiqingatha ijika i-counterclockwise. ., ukuba isantya esiphezulu asikwazi ukufikelela kuyo, vula inaliti ye-H nge-clockwise 1/8 ixesha ngalinye ukuba isantya esingenamsebenzi siqhelekile kwaye i-throttle icinyiwe, vula inaliti ye-L 1/8 ngexesha ngalinye;
5. I-carburetor ivalekile, icocekile okanye iyitshintshe.

Inkqubo yokukhupha:

1. I-muffler ivalwe ngekhabhoni, khupha idiphozithi yekhabhoni okanye usebenzise umlilo ukuyisusa
2. I-cylinder exhaust port ivalwe ngeediphozithi zekhabhoni, zikhuphe iidiphozithi zekhabhoni

Isekethe:

Iphakheji ye-voltage ephezulu yonakele ngaphakathi kwaye idinga ukutshintshwa.
