Ntchito ya gudumu la chizindikiro cha crankshaft.
Ntchito yaikulu ya gudumu la chizindikiro cha crankshaft ndikuzindikira molondola malo ndi ngodya ya crankshaft, komanso liwiro la injini. Nthawi zambiri imagwira ntchito limodzi ndi masensa a camshaft kuti iwonetsetse kuti injini ikugwira ntchito bwino komanso kuti igwire bwino ntchito. Kunena zoona:
Dziwani malo a crankshaft: Gudumu la chizindikiro cha crankshaft, kudzera mu kapangidwe kake ndi malo ake, limalola sensa kuzindikira molondola malo omwe alipo ndi Ngodya ya crankshaft, zomwe ndizofunikira kwambiri powongolera nthawi yoyatsira ndi kulowetsa mafuta.
Kugwira ntchito ndi sensa ya malo a camshaft: Gudumu la chizindikiro cha crankshaft limagwira ntchito ndi sensa ya malo a camshaft kuti lidziwe nthawi yoyambira yoyatsira. Mgwirizanowu umatsimikizira kuti injini ikhoza kuyatsidwa panthawi yoyenera kuti igwire ntchito bwino komanso momasuka.
Gudumu la chizindikiro cha crankshaft nthawi zambiri limagwiritsidwa ntchito ndi gudumu la chizindikiro cha mano 60-2, pali gawo la dzino lomwe likusowa, ndi sensa malinga ndi mawonekedwe a dzino ndi chizindikiro chapamwamba komanso chotsika cha gawo la dzino lomwe likusowa kuti liweruze gawo loyamba la crankshaft. Kapangidwe kameneka kamalola sensa kuweruza molondola malo ndi gawo la crankshaft kudzera mu mawonekedwe a dzino ndi zizindikiro zapamwamba komanso zotsika za dzino lomwe likusowa, , motero kukwaniritsa kuwongolera kolondola kwa momwe injini imagwirira ntchito. Kapangidwe kapadera ka gudumu la chizindikiro cha crankshaft, kuphatikiza ndi kukonza chizindikiro cha crankshaft ndi ECU (electronic control unit) , ndi imodzi mwaukadaulo wofunikira kwambiri kuti injini igwire bwino ntchito komanso mokhazikika.
Kuyang'anira liwiro la injini: Gudumu la chizindikiro cha crankshaft limayang'aniranso liwiro la injini ndikutumiza deta ku ECU (electronic control unit) kuti ilamulire bwino nthawi yoyatsira ndi nthawi yojambulira, zomwe ndizofunikira pakukweza kugwiritsa ntchito bwino mafuta ndikuchepetsa mpweya woipa.
Mwachidule, gudumu la chizindikiro cha crankshaft ndi gawo lofunika kwambiri mu injini zamakono, zomwe zimathandiza makina owongolera injini kukonza magwiridwe antchito ndikuwonetsetsa kuti ikugwira ntchito bwino popereka chidziwitso cholondola cha malo ndi liwiro.
Kodi zizindikiro za kulephera kwa crankshaft signal disk ndi ziti?
Ngati diski ya chizindikiro cha crankshaft yalephera, idzakhala ndi zotsatira zingapo pa ntchito yabwinobwino ya galimoto, makamaka motere:
Choyamba, chizindikiro cha cholakwika chimayatsa, chomwe ndi momwe makina odziwonera okha a galimotoyo atazindikira vutolo. Chachiwiri, mukayamba galimoto, mutha kupeza kuti njira yoyambira ndi yayitali kuposa masiku onse, chifukwa injini ikuyesera kuyamba bwino kudzera mu sensa ya camshaft position, koma chifukwa cha vuto la disk ya chizindikiro, njira yoyambira imalephereka. Poyendetsa galimoto, ntchito yoyendera ya galimotoyo ingakhudzidwe ndipo singagwire ntchito bwino. Kuphatikiza apo, injiniyo ingawoneke ngati ikugwedezeka molakwika, komanso kutulutsa utsi woyera.
Ntchito yaikulu ya sensa ya malo a crankshaft ndikuwunika liwiro la injini, ndipo malinga ndi izi kudziwa kuchuluka kwa mafuta omwe amalowa ndi ngodya yoyatsira moto. Izi zimatsimikizira kuti injini yayatsidwa ndi kuyatsidwa panthawi yoyenera, motero kuchepetsa kuwonongeka kwa galimotoyo. Komabe, pakakhala vuto ndi gulu la chizindikiro cha crankshaft, ntchito zowunikira ndi kusintha izi zitha kukhudzidwa, zomwe zimapangitsa kuti injini isagwire bwino ntchito.
Sensa yoikapo crankshaft nthawi zambiri imayikidwa mu distributor, yomwe ndi gawo lofunikira pozindikira malo a TDC a piston, kotero nthawi zina imatchedwa sensa ya TDC. Sensa iyi ikalephera, iyenera kuyang'aniridwa ndikukonzedwa nthawi yomweyo kuti kulephera kusakule ndikuwononga galimotoyo kwambiri.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
