Zambiri pazithunzi za Maubwenzi

Mtundu woyamba wa Dawzhba unyolo unapangidwa mu 1953, ndipo anamasulidwa mu 1955. Anapangidwa pamakampani opanga makina m'mizinda ya Biysk ndi Perm. Mitundu yonse yamatcheni amtunduwu imakhala ndi injini yama sitimayi yofanana ndi yoziziritsa komanso yoziziritsa mpweya komanso yoziziritsa kukhosi. Chifukwa cha kapangidwe kake kosavuta ndi zipatso zambiri, Ubwenzi ukufunabe, ndipo macheke a mitundu yoyambirira nawonso akugwira ntchito. Cholinga chachikulu cha unyolo wa Druzhba chikugwa ndikusoka mitengo.

Musanagwiritse ntchito unyolo uliwonse, muyenera kuphunzira malangizo kuchokera kwa wopanga ndikutsatira malamulo onse otetezeka.

Ma Model a Chainsaw

Mawonekedwe onse a macheka sanasinthe kwenikweni pakapita nthawi, ndizokhazo zomwe zimatsimikizidwa. Nambala yomwe ili kumapeto kwa dzina lachitsanzo imawonetsa mphamvu yake, mwachitsanzo, Ubwenzi 2 - 2 hp Mu tcheni chakumasulidwa koyamba, ma handini adalumikizidwa pachikuto cha mafani, pambuyo pake adayamba kuphatikiza ndi opindika omwe amalumikiza gearbox ndi injini. Mu mtundu wa 4A, wopangidwa zaka za 80s zisanachitike, makina ochitira kulumikizana ndi magneto ndi KMP-100 anali atagwiritsidwa kale ntchito. Komanso, kuthira kwamoto wokha Pambuyo pake idayimitsidwa ndipo choyimira cha 4A-Electron chokhala ndi kuyatsidwa kwa zamagetsi chidayambitsidwa m'malo mwake.

Mu 90s, carburetor wam'mbuyomu adasinthidwa ndi KMP-100U yatsopano. Chingwecho chinayamba kutchedwa Friendship-4M ndipo chinali ndi maunyolo osinthidwa. Pamaziko a Dawzhba unyolo, Ural saw inapangidwa ndi machitidwe amphamvu kwambiri. Mtundu womaliza wopangidwa wokhala ndi mawonekedwe ofanana ndi Ubwenzi 5E.

Zizindikiro zowonjezera ndi chilembo E kapena mawu akuti "Electron" amatanthauza kuti njira yoyatsira yamagetsi imagwiritsidwa ntchito mu unyolo.

Makhalidwe

Ubwenzi 2

Mtunduwu wakhala umodzi wodziwika kwambiri pamitundu yonse yoyambira. Druzhba-2 chainsaw imagwira ntchito chifukwa cha injini yamagalimoto awiri yamphamvu-imodzi yamphamvu kwambiri pafupifupi 2.2 kW yokhala ndi liwiro la 3200 rpm. Poyerekeza ndi mtundu wakale, izi zimachitidwa moyenera. Chingwe ndi chogwirira chimapangidwa kuti ogwiritsira ntchito asatenthedwe pa injini yotentha. Mlanduwo umapangidwa ndi alloy apamwamba kwambiri, omwe saopa kusintha kwa kutentha. Mosiyana ndi mtundu woyamba, uyu ali kale ndi makina ochita kupanga kuti azitha kugwiritsa ntchito mosamala. Pakubwezeredwa kapena kuphulika, kuyimitsa unyolo. Chingwe chake chinali choti chizipangira zosowa zapakhomo komanso kuti ntchito yaukadaulo ikhale yabwino. Kulemera makilogalamu 12.5.

Ubwenzi 4

Ubwenzi 4 umagwiritsa ntchito injini yofanana ndi yam'mbuyomu, koma mphamvu zambiri - 4 hp. kapena 2.94 kW. Injini ndi mphamvu yamagetsi zimayikidwa pogwiritsa ntchito kulumikizana kwa flange komwe kumakhala kotetezeka. Injini, ngati pakufunika (kukonza, kukonza), ikhoza kuchotsedwa mosavuta pazinthu zilizonse. Pamaziko a Druzhba 4 saw, masinthidwe awiri adapangidwa ndi zilembo 4A ndi 4E. Yoyamba idawonjezeredwa ku makina oyenda okhaokha othira, ndipo yachiwiri idagwiritsa ntchito kuyatsa kwamagetsi. Zolakwika za zitsanzo zam'mbuyomu zidachitidwanso chidwi, mwachitsanzo, mawonekedwe a crankshaft adalimbikitsidwa. Matembenuzidwe onse adaperekedwa ndi dongosolo lothamanga mwadzidzidzi.

Munthawi yaubwenzi wa 4M-Electron, injini yofanana ndi mphamvu ya 2.94 kW komanso liwiro la 5200 rpm imagwiritsidwa ntchito. Silindayo amapangidwa ndi aluminiyamu, ndipo ma waya amkati kuchokera mkati kuti amalimbitse kutsutsana. Mosiyana ndi matembenuzidwe am'mbuyomu, chainaw iyi imakhala ndi gearbox yotembenuzira yomwe imakulolani kuti muzitha kuzungulira gawo 60-90 ° kuti mugwire ntchito mosavuta. Kulemeraku kumagawidwa wogawana thupi lonse kuti ntchitoyo ikhale yabwino. Palinso chida chosinthira madzi chomwe chili pakati pa gudumu loyendetsa ndi ma handles, struts ndi tank yamagesi.

Kuti muchepetse phokoso, sawowa ali ndi kanyimbo, ndipo phokoso ndi la 106 dB. Carburetor ya KMP-100U kapena KMP-100-AR imayikidwa mu Druzhba 4M-Electron. Pali machitidwe ena akukhomeka ndi kuwiritsa kwa tona. Kulemera makilogalamu 12.5.

Ubwenzi-5E

Mtundu waposachedwa kwambiri wamtunduwu wamatcheni. Wokhala ndi injini yama sitiroko imodzi yamphamvu-imodzi yamphamvu ya 5 hp kapena 3,7 kW. Tithokoze chifukwa chake magwiridwe ake ndi apamwamba kwambiri kuposa a mitundu yapitayi. Kuthamanga kuthamanga 6200 rpm. Nthawi yomweyo, mulingo wa phokoso ndi wotsika pang'ono kuposa wa Druzhba-4M Electron, ndipo ndi 105 dB. Kulemera kwa 5E chainsaw ndi 800 g yochepa - 11.7 kg.

Gome lokhala ndiukadaulo wamakhalidwe aubwenzi:

Ubwino ndi zoyipa

Makhalidwe abwino aubwenzi wa maubwenzi a Friendship:

• ntchito yayikulu komanso kuthekera kwa nthawi yayitali popanda kusokonezedwa kwa mphindi 50;
• zomanga zosavuta;
• kupezeka kwa magwiridwe apamwamba, chifukwa chomwe mungadule pamalo oyimilira, amathandizanso kugwiritsa ntchito bwino komanso kuchepetsa kugwedezeka;
• malo opezeka zigawo zonse;
• tcheni chimayendetsedwa ndi kuthamanga kwa injini;
• mafuta ochepa a octane angagwiritsidwe ntchito;
• kupezeka kwa kubedwa kwadzidzidzi mu mitundu yambiri;
• unyolo ukakomoka, sawona sangasunthike;
• molondola ngakhale kudula;
• moyo wautumiki, malinga ndi malamulo ogwiritsira ntchito ndi chisamaliro choyenera, ungakhale wazaka 15 mpaka 30.

Choyipa chachikulu ndikulemera kwambiri. Komanso, chifukwa choti woyambitsa sangachotsedwe, nthawi zambiri amatayika, ndipo palibe batani loyimitsa.

Osagwiritsa ntchito mafuta oyendetsedwa ngati mafuta kapena kuyambitsa sopo m'chipinda chotseka.

Malangizo Okonza

Chifukwa cha kapangidwe kake kosavuta, Kukonzanso kwa Chainsaw kutha kuchitika ndi manja anu. Chifukwa, mwachitsanzo, pamagetsi amtunduwu nthawi zambiri pamakhala zovuta zokusautsa, makamaka ngati kulumikizana kukhazikitsidwa. Amakhudzidwa kwambiri ndi mafuta ndi mafuta osiyanasiyana. Chifukwa chake, ndibwino kugula kuyatsa kwamagetsi m'malo mwake. Komanso, zolumikizana zamaubwenzi ndi zopereka sizotsika mtengo komanso zosakwaniritsidwa.

Ngati makandulo adzaza kwambiri, ndiye kuti muyenera kulabadira carburetor. Poterepa, ndikofunikira kupukusa pang'ono valavu yamagesi mkati, chifukwa chake, kuchuluka kwa mafuta omwe amaperekedwera kumatsika ndipo makandulo amasiya kunyowa.

The carburetor amathanso kusintha:

1. Choyimira mafuta chimakhala cholimba kwathunthu ndikutsegula kumbuyo 3 kutembenuka.
2. Wotsatsira amatseka kwathunthu ndipo amatembenuka ma 2.

Kuti mpweya usakodwe munthaka kuchokera kunja, zisindikizo zonse ziyenera kukhala zopanda mpweya.

Poyerekeza ndi mitundu ina ya chainsaw, Ubwenzi umagulitsidwa pamtengo wotsika, chifukwa chochepa ntchito, koma uli ndi luso labwino komanso moyo wautali, womwe mitundu yomwe idatengedwa siyingadzitame.
