87cc 4.2KW Big Power Chain saw Kwa 288 870

Chida chilichonse chamunda chomwe chagwiritsidwa ntchito kwa nthawi yayitali chidzakumana ndi zovuta zazikulu kapena zazing'ono. Kaya zolakwazo zitha kuthetsedwa mwachangu zikukhudzana mwachindunji ndi kukulitsa moyo wake wautumiki ndikusunga magwiridwe antchito abwino. Kutenga chitsanzo cha chainsaw, ngati simukumvetsa kalikonse ndikufunsana ndi katswiri nthawi iliyonse pakakhala vuto, zingakhale zovuta kwambiri. Komabe, ngati mumvetsetsa zolakwika zina za ma chainsaws, mutha kuthetsa zolakwa zosavuta.

Kuvuta kuyambitsa kozizira kwa chainsaw

Pamene chainsaw yayambika, injiniyo imangopanga phokoso lochepa chabe popanda chodabwitsa chilichonse choyaka. Ngakhale zitayamba mobwerezabwereza, zimakhalabe chimodzimodzi. Izi mwachiwonekere si vuto la kupsinjika kwa silinda pang'ono kapena kutayikira mu crankcase, komanso si vuto la kuwonongeka kwa ma spark plugs ndi mawaya amphamvu kwambiri amagetsi oyatsira, kapena mphamvu ya maginito yosakwanira ya maginito. Izi zili choncho chifukwa cha kukanikiza kosakwanira, kutayikira mu crankcase, kutayikira kwa ma plug plugs ndi mawaya othamanga kwambiri, kutsika kwamphamvu kwa maginito achitsulo, komanso mphamvu ya maginito yosakwanira, zomwe zimapangitsa kuti injiniyo isaphulike. Ngati cholakwikacho chiri mu dongosolo loyatsira, ngati ndi injini yolumikizana ndi magneto poyatsira, cholakwikacho chimakhala chifukwa cha malo osagwirizana, kuyaka, madontho amafuta, ndi kudzikundikira kwa zigawo za oxide; Zitha kuchitikanso chifukwa cha kusweka kwa kiyi ya flywheel theka la mwezi ndi kasupe wolumikizana ndi rocker arm, komanso kumasuka kwa mkono wa rocker wosunthika. Ngati ndi magneto osalumikizana, ambiri amakhala chifukwa chosalumikizana bwino ndi cholumikizira cha koyilo.

Ngati vuto limachitika pamakina operekera mafuta, makamaka chifukwa cha chinyezi mumafuta, mpweya mupaipi yamafuta, komanso mafuta ochulukirapo kapena olemera opaka mafuta mumafuta osakanikirana, zomwe zingayambitse injini kuyaka mosalekeza poyambitsa injini yozizira. . Chifukwa mphamvu yokoka yamadzi ndi yayikulu kuposa mafuta, amayika pansi pa thanki yamafuta. Injini ikayamba, mafuta mu carburetor amatha kuperekedwa kwakanthawi kuyaka ndi kuphulika kwakanthawi. Madzi awa mu thanki yamafuta akalowa mu carburetor kapena chitoliro chamafuta, amachotsa mafuta omwe amakhalapo, ndipo injiniyo imasiya kuphulika nthawi yomweyo. Kuonjezera apo, mafuta odzola kwambiri mu mafuta amachititsa kuti atomization ya mafuta ikhale yofulumira, zomwe zimapangitsa kuti zikhale zovuta kuti osakaniza ayambe kuyatsa, nthawi zina amawotcha, komanso osapitirira. Mafuta osakanikiranawo ndi olemera kwambiri, ndipo ngakhale atatha kuyatsidwa ndi mphamvu yamphamvu atatha kulowa mu silinda, "amamira" mwamsanga chifukwa cha kuchuluka kwa mafuta (ndiko kuti, kutsekemera kozungulira pakati pa mtengo wa spark). pulagi ndi pakati pa mitengo yam'mbali zonse zimadzazidwa ndi kudzikundikira mafuta). Ngati mafuta osakanikirana achuluka kwambiri kapena mafuta odzola ochuluka mu mafuta osakaniza, mpweya wotulutsa mpweya umene umatulutsidwa ndi mpweya wotulutsa mpweya panthawi ya kuphulika uyenera kukhala utsi wakuda wakuda.

Kutentha kwakukulu kwa chainsaw

Chizindikiro chodziwika bwino ndi chakuti pambuyo pogwira ntchito kwa nthawi ndithu, injiniyo imayima mwadzidzidzi ndipo siingathe kukokedwa. Zimatenga nthawi kuti uyambitse moto, ndipo pambuyo pogwira ntchito kwa nthawi ndithu, izi zimachitikanso, ndipo zimachitika kawirikawiri nyengo yotentha. Zomwe zili pamwambazi ndizochitika zomwe ma chainsaw amasungira kutentha kwambiri. Kodi tiyenera kuchita chiyani pamenepa? Choyamba, tiyenera kuzindikira zifukwa zake. Zomwe zimayambitsa komanso njira zothetsera vutoli ndi izi:

1. Nkhani za mpweya wabwino

Makamaka chifukwa chosowa mpweya wabwino wa crankcase ndi pulasitiki, zomwe zimabweretsa mpweya wabwino wa zigawo za carburetor ndikuyambitsa kutentha kwambiri.

Yankho: Mpweya wabwino. Ngati chovundikira chowongolera mpweya chiwonjezedwa pa maginito flywheel kapena njira yapakati pa maginito flywheel ndi carburetor pa crankcase imatha kutsegulidwa, kuchuluka kwa mpweya wabwino kumatha kuonjezedwa, kapena chivundikiro cha bokosi lokhala ndi mpweya wabwino ndi zida zophimba mpweya zitha kusinthidwa.

2. Kutopa kosakwanira kwa muffler komwe kumatsogolera kutentha kwambiri

Yankho: Tsukani chowumitsira chopondera kapena m'malo mwake ndi chotsekera ndi bowo lalikulu la utsi. (Zindikirani: kukhala ndi mabowo ambiri sikutanthauza kuwakonza mwachangu. Pamsika, mabowo awiri akuluakulu ndi abwino kuposa mabowo ang'onoang'ono atatu.).

3. Kutsika kwa kutentha kwa carburetors

Yankho: Onjezani zotchinjiriza mapepala, mpweya, kuyeretsa kapena kusintha ma carburetor.

4. Phukusi la coil / high-voltage silingagwirizane ndi kutentha kwakukulu

Yankho: Sinthani mwachindunji.

5. Zigawo zitatu za silinda

Chimodzi mwazinthu zitatuzi, silinda, pisitoni, ndi mphete ya pisitoni, ndi yazinthu zopanda pake.

Yankho: Bwezerani silinda yamanja ya chainsaw.

6. Zisindikizo zamafuta ndi mapaipi opondereza olakwika (mapaipi oyendera gasi) sagonjetsedwa ndi kutentha kwambiri.

Chisindikizo chamafuta ndi chitoliro choyipa (chitoliro cha gasi) sichimalimbana ndi kutentha kwambiri, zomwe zimapangitsa kuti mpweya utuluke pamene kutentha kuli kwakukulu.

Yankho: Bwezerani chisindikizo chamafuta apamwamba kwambiri komanso chitoliro choyipa choyipa (chitoliro cha mpweya wabwino).
