87cc 4.2KW Big Power Chain Saw ya 288 870

Chida chilichonse cha m'munda chomwe chagwiritsidwa ntchito kwa nthawi yayitali chidzakumana ndi zovuta zazikulu kapena zazing'ono. Kaya zolakwikazo zitha kuchotsedwa mwachangu zikugwirizana mwachindunji ndi kukulitsa nthawi yake yogwirira ntchito komanso kusunga magwiridwe antchito abwino. Mwachitsanzo, ngati simukumvetsa chilichonse ndikufunsa katswiri nthawi iliyonse pakakhala vuto, lingakhale lovuta kwambiri. Komabe, ngati mukumvetsa zolakwika zina zodziwika bwino zokhudza ma chainsaw, mutha kuthetsa mosavuta zolakwika zosavuta.

Kuvuta kuyambitsa choziziritsira cha chainsaw

Pamene chainsaw yayatsidwa, injini imangopanga phokoso lochepa popanda kuyatsa kosalekeza. Ngakhale ikayambanso mobwerezabwereza, imakhalabe chimodzimodzi. Izi sizikutanthauza kuti vuto la kupsinjika kwa silinda yochepa kapena kutuluka kwa madzi mu crankcase, komanso si vuto la kuwonongeka kwa ma spark plugs ndi mawaya amphamvu a dongosolo loyatsira, kapena mphamvu ya maginito yosakwanira ya magneto. Izi zimachitika chifukwa cha kupsinjika kosakwanira, kutuluka kwa madzi mu crankcase, kutuluka kwa ma spark plugs ndi mawaya amphamvu, kuchotsedwa kwa maginito kosatha kwa chitsulo cha maginito, komanso mphamvu ya maginito yosakwanira, zomwe zimapangitsa kuti injini isaphulike. Ngati cholakwika chili mu dongosolo loyatsira, ngati ndi injini yokhala ndi kuyatsa kwa maginito, vutolo limachitika makamaka chifukwa cha malo olumikizirana otayirira, kuyaka, madontho a mafuta, ndi kusonkhana kwa zigawo za oxide; Zingachitikenso chifukwa cha kusweka kwa kiyi ya mwezi wa flywheel ndi kasupe wa mkono wa contact rocker, komanso kumasuka kwa mkono wa contact rocker wosuntha. Ngati ndi magneto yosalumikizana, zambiri zake zimachitika chifukwa cha kukhudzana koyipa pa cholumikizira cha coil.

Ngati vuto lachitika mu dongosolo loperekera mafuta, makamaka chifukwa cha chinyezi mu mafuta, mpweya mu chitoliro cha mafuta, ndi mafuta ochulukirapo kapena olemera mu mafuta osakanikirana, zomwe zingayambitse injini kuyaka mosalekeza poyatsa injini yozizira. Chifukwa mphamvu yeniyeni ya madzi ndi yayikulu kuposa ya mafuta, imayikidwa pansi pa thanki yamafuta. Injini ikayamba, mafuta mu kabureta amatha kuperekedwa kokha kuti ayake ndi kuphulika kwakanthawi. Madzi awa mu thanki yamafuta akalowa mu kabureta kapena chitoliro chamafuta, amadula mafuta wamba, ndipo injini nthawi yomweyo imasiya kuphulika. Kuphatikiza apo, mafuta ochulukirapo mu mafuta amakhudza kupangika kwa mafuta mwachangu, zomwe zimapangitsa kuti kusakanizako kuyake, nthawi zina kuyaka, ndikusiya. Mafuta omwe ali mu chisakanizocho ndi ochuluka kwambiri, ndipo ngakhale atayatsidwa ndi cheza champhamvu atalowa mu silinda, "amamira" mwachangu chifukwa cha kuchuluka kwa mafuta (ndiko kuti, chotenthetsera chozungulira chitsulo chapakati cha chitsulo chotenthetsera ndipo pakati pa chitsulo cham'mbali zonse zimadzazidwa ndi kuchuluka kwa mafuta). Ngati pali mafuta osakanikirana kwambiri kapena mafuta opaka mafuta ambiri mu mafuta osakanikirana, mpweya wotulutsa utsi wotuluka ndi chotenthetsera utsi panthawi ya kuphulika uyenera kukhala utsi wakuda wandiweyani.

Kutseka kwa chainsaw kutentha kwambiri

Chizindikiro chofala kwambiri ndi chakuti injini ikagwira ntchito kwa nthawi ndithu, mwadzidzidzi imayima kenako singathe kukokedwa. Zimatenga nthawi kuti iyatse moto, ndipo ikagwira ntchito kwa nthawi ndithu, vutoli limabweranso, ndipo limachitika kawirikawiri nyengo yotentha. Zomwe zili pamwambapa ndi zochitika zomwe zimachitika kawirikawiri pamene ma chainsaw amayima kutentha kwambiri. Kodi tiyenera kuchita chiyani pankhaniyi? Choyamba, tiyenera kuzindikira zifukwa zake. Zomwe zimayambitsa komanso njira zothetsera vutoli ndi izi:

1. Mavuto okhudza mpweya wabwino

Makamaka chifukwa cha mpweya wochepa wa crankcase ndi pulasitiki, zomwe zimapangitsa kuti zinthu za carburetor zisamayende bwino komanso kutentha kwambiri kuchedwe.

Yankho: Mpweya wopumira. Ngati chivundikiro cha mpweya chowongolera chawonjezeredwa pa flywheel yamaginito kapena njira pakati pa flywheel yamaginito ndi carburetor pa crankcase ingatsegulidwe, kuchuluka kwa mpweya wopumira kungawonjezeke, kapena chivundikiro cha bokosi lopumira bwino komanso chophimba mpweya chofewa chingasinthidwe.

2. Kutulutsa mpweya woipa wa muffler zomwe zimapangitsa kuti kutentha kukhale kwakukulu

Yankho: Tsukani choletsa mpweya kapena chisintheni ndi choletsa mpweya chokhala ndi dzenje lalikulu lotulutsa utsi. (Dziwani: kukhala ndi mabowo ambiri sikutanthauza kuti azikonza mwachangu. Pamsika, mabowo akuluakulu okhala ndi mabowo awiri ndi abwino kuposa mabowo ang'onoang'ono atatu.).

3. Kukana kutentha kochepa kwa ma carburetor

Yankho: Onjezani mapepala oteteza kutentha, tsegulani mpweya, yeretsani kapena sinthani ma carburetor.

4. Phukusi la coil/high-voltage sililimbana ndi kutentha kwambiri

Yankho: Sinthanitsani mwachindunji.

5. Zigawo zitatu za silinda

Chimodzi mwa zigawo zitatuzi, silinda, pistoni, ndi mphete ya pistoni, ndi chosalimba.

Yankho: Sinthani silinda yachitsulo cha chainsaw.

6. Mapaipi otsekera mafuta ndi mapaipi oletsa kupanikizika (mapaipi a mpweya olinganiza bwino) salimbana ndi kutentha kwambiri

Chitseko cha mafuta ndi chitoliro chotsutsa mpweya (chitoliro cha mpweya cholinganiza bwino) sizimalimbana ndi kutentha kwambiri, zomwe zimapangitsa kuti mpweya utuluke kutentha kwambiri.

Yankho: Sinthani chisindikizo cha mafuta chapamwamba kwambiri ndi chitoliro chopanikizika chopanda mphamvu (linganiza chitoliro cha mpweya).
