Kodi malamba akutsogolo kwa injini amachita chiyani?

Kalelo "masiku akale", injini zoyatsira mkati zimagwiritsa ntchito malamba ndi ma pulleys kuyendetsa zinthu monga mapampu amadzi kapena makina owongolera mpweya. Ngakhale ukadaulo wapita patsogolo, malamba akadali chinthu chofunikira kwambiri pamagalimoto ambiri, magalimoto ndi ma SUV. Ngakhale galimoto iliyonse ili ndi makina apadera oyendetsa lamba opangidwira mainjini ndi masinthidwe osiyanasiyana, nthawi zambiri pamakhala mitundu iwiri ya malamba: malamba owonjezera kapena nthiti ndi malamba anthawi.

Lamba wowonjezera, womwe uli kutsogolo kwa injini, ndi gawo lofunikira lomwe limayendetsa ntchito zambiri zamagalimoto. Atha kutchedwanso lamba wa serpentine, yemwe amamveka mwachinsinsi kwambiri koma amatanthauza zomwezo. Chifukwa cha dzina lake ndi chakuti imazungulira ma pulleys osiyanasiyana monga njoka; choncho mawu akuti serpentine. Lamba uyu amayendetsa zinthu zingapo zowonjezera monga pampu yamadzi, fan ya radiator, alternator ndi makina owongolera mpweya.

Lamba wanthawi yayitali amayikidwa pansi pa chivundikiro cha injini ndipo amapangidwa kuti aziyendetsa crankshaft kapena camshaft, yomwe imayendetsa nthawi ya zida zonse zamkati za injini monga ma pistoni ndi ma valve. Pazolinga za nkhaniyi, tiyang'ana kwambiri lamba wa serpentine.

Momwe lamba wa njoka amagwirira ntchito

Lamba limodzili limalowa m'malo mwa lamba angapo omwe amagwiritsidwa ntchito pamainjini. Mu zitsanzo zakale, panali lamba mmodzi pa chowonjezera chilichonse. Vuto linali lakuti ngati lamba mmodzi anathyoka, munkafunika kuvula onsewo n’kulowetsamo lamba wolakwikawo. Sikuti nthawiyi inkangotenga nthawi, koma nthawi zambiri zimatengera ogula ndalama zambiri kulipira makaniko kuti agwire ntchitoyo.

Lamba wa njoka adapangidwa kuti athetse mavutowa. Lamba wa serpentine kapena wowonjezera amawongolera zigawo zonsezi. Imayendetsedwa ndi crankshaft pulley ndikulowa ndikutuluka m'mapule osiyanasiyana othandizira. Magalimoto ena amatha kukhala ndi lamba wodzipatulira pazinthu zina, koma nthawi zambiri lamba limodzi limagwira ntchito zingapo. Izi zimachepetsa kuchuluka kwa ntchito yofunikira kuti mulowe m'malo mwa lamba wosweka komanso kumachepetsa kukokera kwa injini. Chotsatira chake ndi njira yabwino kwambiri yomwe imasunga zigawo zonse zoyendetsedwa ndi lamba zikuyenda bwino.

Kodi lamba wa serpentine amakhala nthawi yayitali bwanji?

Lamba wa V-nthiti amagwiritsidwa ntchito nthawi iliyonse injini ikayambika, ndipo ntchito yosalekeza imeneyi imayambitsa kuvala koopsa. Monga chigawo china chilichonse cha rabala mu injini ya injini, imakhala ndi kutentha kwakukulu ndipo imatha pakapita nthawi. Moyo wautumiki wa lamba wa serpentine makamaka umadalira mtundu wa zinthu zomwe zimapangidwira. Malamba akale amatalika pafupifupi ma 50,000 mailosi, pomwe malamba opangidwa kuchokera ku EPDM amatha mpaka 100,000 mailosi.

Njira yabwino ndiyo kuyendetsa galimoto yanu pafupipafupi ndikuwunika lamba nthawi iliyonse mukasintha mafuta a injini ndi fyuluta. Ndikulimbikitsidwanso kuti lamba ndi ma pulleys aziyang'aniridwa nthawi iliyonse yokonza pa radiator kapena makina ozizira. Ngati itasweka, mudzapeza kuti luso lanu loyendetsa galimoto lasintha kwambiri. Popanda lamba uyu, pampu yanu yowongolera mphamvu sigwira ntchito, makina anu oziziritsira mpweya sangagwire ntchito, ndipo alternator yanu sigwira ntchito. Galimoto imathanso kutenthedwa chifukwa mpope wamadzi sugwira ntchito, zomwe zimatha kuwononga injini mwachangu.

Nthawi iliyonse mukasintha lamba wa V-nthiti, tikulimbikitsidwa kuti musinthe ma pulleys ndi tensioner nthawi yomweyo. Ntchitoyi iyenera kuchitidwa ndi makaniko wophunzitsidwa mwaukadaulo, kotero funsani makaniko okonza a m'dera lanu kuti alowe m'malo mwa lamba wa V-nthiti monga momwe wopanga amapangira.
