I-Big Power Chain Saw engu-87cc engu-4.2KW ye-288 870

Noma yiliphi ithuluzi lengadi elisetshenziswe isikhathi eside lizobhekana nokungasebenzi kahle okukhulu noma okuncane. Ukuthi amaphutha angasuswa ngokushesha kuhlobene ngqo nokwandisa isikhathi salo sokusebenza nokugcina ukusebenza kahle kokusebenza. Uma sithatha i-chainsaw njengesibonelo, uma ungaqondi lutho futhi uthintane nochwepheshe noma nini lapho kunenkinga, kungaba yinkinga kakhulu. Kodwa-ke, uma uqonda amaphutha athile avamile mayelana ne-chainsaw, ungaxazulula kalula amaphutha alula.

Ubunzima bokuqala i-chainsaw cooler

Uma i-chainsaw iqalwa, injini yenza umsindo omncane kuphela ngaphandle kwento eqhubekayo yokushisa. Ngisho nangemva kokuqalisa okuphindaphindiwe, isalokhu injalo. Lokhu kusobala ukuthi akuyona inkinga yokucindezela kwesilinda esiphansi noma ukuvuza ku-crankcase, futhi akuyona inkinga yokulimala kwama-spark plugs nezintambo eziphezulu zesistimu yokushisa, noma amandla anganele kazibuthe e-magneto. Lokhu kungenxa yokucindezela okunganele, ukuvuza ku-crankcase, ukuvuza kwama-spark plugs nezintambo eziphezulu ze-voltage, ukususwa komagnetization unomphela kwensimbi yamagnetic, kanye namandla anganele kazibuthe, okwenza kube nzima ukuthi injini iqhume. Uma iphutha lisesimisweni sokushisa, uma kuyinjini ene-contact magneto ignition, iphutha libangelwa kakhulu amaphuzu okuxhumana akhululekile, ukusha, amabala kawoyela, kanye nokuqongelela kwezingqimba ze-oxide; Kungabangelwa futhi ukuphuka kwe-flywheel half moon key kanye ne-contact rocker arm spring, kanye nokukhululeka kwengalo ye-contact rocker eshukumayo. Uma kuyi-magneto engaxhumani, iningi layo libangelwa ukuxhumana okungekuhle esixhumini se-coil.

Uma iphutha livela ohlelweni lokuhlinzeka ngophethiloli, ikakhulukazi libangelwa umswakama kuphethiloli, umoya epayipini likaphethiloli, kanye namafutha okugcoba amaningi noma acebile kuphethiloli oxubile, okungabangela ukuthi injini ivuthe ngokungaqhubeki lapho iqala injini ebandayo. Ngenxa yokuthi amandla adonsela phansi amanzi makhulu kunophethiloli, ahlala phansi ethangini likaphethiloli. Lapho injini iqala, uphethiloli ose-carburetor unganikezwa kuphela ukuze kushiswe okwesikhashana futhi kuqhume. Lapho la manzi asethangini likaphethiloli engena epayipini likaphethiloli noma likaphethiloli, anqamula ukunikezwa okuvamile kukaphethiloli, futhi injini iyayeka ukuqhuma ngokushesha. Ngaphezu kwalokho, uwoyela okugcoba ngokweqile kuphethiloli uthinta ukwakheka okusheshayo kukaphethiloli, okwenza kube nzima ngengxube ukuthi ivuthe, ngezinye izikhathi ivuthe, futhi iphele. Uphethiloli osengxubeni ucebile kakhulu, futhi noma ungavuthelwa yinhlansi enamandla ngemva kokungena esilinda, uzoshesha "ucwile" ngenxa yokuqongelela uwoyela omningi kakhulu (okungukuthi, ukufudumala okuzungeze insingo ephakathi yepulaki yenhlansi futhi phakathi kwezinsingo eziseceleni konke kugcwele ukuqongelela uwoyela). Uma kukhona uphethiloli omningi kakhulu noma uwoyela wokugcoba omningi kakhulu ku-oyela oxubile, igesi yokukhipha umoya ekhishwa yi-exhaust muffler ngesikhathi sokuqhuma kumele ibe yintuthu emnyama ejiyile.

Ukuvalwa kwezinga lokushisa eliphezulu kwe-chainsaw

Uphawu oluvamile ukuthi ngemva kokusebenza isikhathi esithile, injini iyama ngokuzumayo bese ingakwazi ukudonswa. Kuthatha isikhathi ukuqala umlilo, futhi ngemva kokusebenza isikhathi esithile, lesi simo siphinde sivele, futhi sivame kakhulu esimweni sezulu esishisayo. Lezi zimo ezingenhla zivamile lapho i-chainsaw ima khona emazingeni okushisa aphezulu. Yini okufanele siyenze kulesi simo? Okokuqala, sidinga ukuthola izizathu. Izimbangela nezixazululo ezivamile yilezi ezilandelayo:

1. Izinkinga zokuphefumula

Ngokuyinhloko kungenxa yokungena kahle komoya kwe-crankcase kanye nezingxenye zepulasitiki, okuholela ekungeneni kahle komoya kwezingxenye ze-carburetor futhi kubangele ukuvimba kokushisa okuphezulu.

Isixazululo: Umoya Ongenamoya. Uma isembozo somhlahlandlela womoya sengezwe ku-flywheel yamagnetic noma isiteshi esiphakathi kwe-flywheel yamagnetic kanye ne-carburetor ku-crankcase singavulwa, izinga lomoya lingakhushulwa, noma ikhithi yesembozo sebhokisi esingenamoya kanye nesembozo sesihlungi somoya ingashintshwa.

2. Ukukhishwa okuncane kwe-muffler okuholela ekushiseni okuphezulu

Isixazululo: Hlanza i-muffler noma uyishintshe nge-muffler enembobo enkulu yokukhipha umoya. (Qaphela: ukuba nembobo eminingi akusho ukuthi kufanele uyihlele ngokushesha. Emakethe, imbobo enkulu enembobo ephindwe kabili ingcono kunembobo encane enembobo emithathu.).

3. Ukumelana nokushisa okuphansi kwama-carburetor

Isixazululo: Faka ama-paper pad okushisa, faka umoya, hlanza noma ushintshe ama-carburetor.

4. Iphakheji yekhoyili/i-high-voltage ayimelani namazinga okushisa aphezulu

Isixazululo: Shintsha ngqo.

5. Izingxenye ezintathu zesilinda

Okungenani enye yezingxenye ezintathu, isilinda, i-piston, kanye nendandatho ye-piston, yenziwe ngezinto ezibuthakathaka.

Isixazululo: Buyisela isilinda se-chainsaw sleeve.

6. Amapayipi kawoyela kanye namapayipi okucindezela angenamandla (amapayipi egesi alinganiselayo) awamelani nokushisa okuphezulu

Ipayipi lokuvala uwoyela kanye nepayipi lokucindezela elibi (ipayipi legesi elilinganiselayo) alimelani namazinga okushisa aphezulu, okuholela ekuvuzeni komoya lapho izinga lokushisa liphezulu.

Isixazululo: Buyisela isivalo sikawoyela sekhwalithi ephezulu kanye nepayipi lokucindezela elibi (bhalansi ipayipi lomoya).
