Kodi sensa ya crankshaft yamagalimoto ndi chiyani?
Sensa ya malo a crankshaft ndi sensa yapakati mu injini zamagalimoto yomwe imagwiritsidwa ntchito kuzindikira malo, liwiro la crankshaft ndi chizindikiro chapakati cha pisitoni chakufa. Chizindikiro chake chimawongolera mwachindunji nthawi yoyatsira ndi nthawi yopangira mafuta, kuonetsetsa kuti injini ikugwira ntchito bwino komanso mokhazikika.
Ntchito yaikulu
Kuzindikira malo a crankshaft: Pogwiritsa ntchito kayendedwe ka mano a disk ya chizindikiro ndi mutu wa maginito, chizindikiro cha pulse chimapangidwa kuti chidziwe malo a pistoni (70° patsogolo pa malo apakati a dead).
Yang'anirani liwiro la injini: Werengani kuchuluka kwa mafuta omwe amazungulira ndikuthandizira ECU kusintha kuchuluka kwa mafuta omwe amalowa ndi ngodya yoyatsira moto.
Kuzindikira kutsatana kwa silinda ndi kuyang'anira kulephera kwa moto: Kuzindikira kutsatana kwa silinda kumachitika kudzera mu kusiyana kwa magawo a zizindikiro za pulse (monga 90°), ndipo zochitika za kulephera kwa moto zimapezeka.
Mitundu yodziwika bwino
Mtundu wa magnetic pulse wa Youdaoplaceholder0 : Umapanga mphamvu yosinthira yamagetsi posintha mphamvu yamagetsi, monga machitidwe a Nissan ndi Toyota.
Youdaoplaceholder0 Fomula ya zotsatira za Hall : Mwa kuzindikira kusintha kwa mphamvu ya maginito kudzera mu zinthu za holo, chizindikiro cha digito chimatuluka.
Mtundu wa Youdaoplaceholder0 photoelectric : Umapanga zizindikiro podalira kutsekedwa kwa njira yowunikira ndipo sugwiritsidwa ntchito kwambiri.
Malo oyika
Injini ya dizilo: Imakhala yokhazikika kwambiri pa flywheel housing kapena pampu yoperekera magetsi.
Injini ya petulo: Imapezeka kwambiri mkati mwa chogawa (monga mu TCCS system ya Toyota) kapena pafupi ndi flywheel.
Kuwonetsa cholakwika
Injini imakhala yovuta kuyiyambitsa, kugwedezeka kapena kuyima.
Kugwiritsa ntchito mafuta mopanda mphamvu kwatsika ndipo mpweya woipa wapitirira muyezo.
Ntchito yaikulu ya sensa ya crankshaft yamagalimoto (yomwe imadziwikanso kuti sensa ya crankshaft position kapena sensa ya liwiro la injini) ndi kuzindikira malo a crankshaft, liwiro la injini ndi zizindikiro zapakati za piston, ndikutumiza deta iyi ku unit control unit (ECU) kuti ilamulire bwino nthawi yoyatsira, nthawi yoyatsira mafuta ndi njira yoyatsira mafuta, kuonetsetsa kuti injini ikugwira ntchito bwino komanso mokhazikika.
Ntchito yaikulu
Sensa ya crankshaft ndi gawo lofunika kwambiri pa makina owongolera zamagetsi a injini. Ntchito zake zazikulu ndi izi:
Youdaoplaceholder0 Dziwani malo a crankshaft ndi ngodya yozungulira : Yang'anirani ngodya yozungulira ya crankshaft nthawi yeniyeni, dziwani malo enieni a pistoni mu silinda, ndikupereka zizindikiro zosonyeza kuyatsa ndi nthawi yoperekera mafuta ku ECU.
Youdaoplaceholder0 imayesa liwiro la injini: Monga sensa yothamanga, imalowetsa chizindikiro cha liwiro mu ECU kuti isinthe mphamvu ya jekeseni ya mafuta ndi ngodya yoyatsira moto, kupewa kulephera kwa jekeseni ya mafuta kapena kuchedwa kuyatsa moto.
Youdaoplaceholder0 Dziwani malo a pakati pa piston pamwamba pakufa : Pezani nthawi yomwe piston ifika pakati pakufa pamwamba (makamaka pakati pakufa pamwamba pa silinda yoyamba), thandizani ECU kukwaniritsa kuyika mafuta motsatizana ndi kusiyanitsa magawo a silinda, ndikuwonetsetsa kuti silinda iliyonse ikugwira ntchito molondola.
Youdaoplaceholder0 imathandizira kuwongolera kothandizira : imatenga nawo mbali m'magawo ang'onoang'ono monga kuwongolera liwiro losagwira ntchito komanso kuwongolera kuphulika kwa mafuta, ndipo imazindikira kusokonekera kwa injini poyang'anira kusinthasintha kwa crankshaft Angle, kukonza bwino kuyaka ndikuchepetsa mpweya woipa.
Mfundo yogwirira ntchito ndi mitundu yake
Masensa a crankshaft amakwaniritsa ntchito zawo kudzera mu kusintha kwa chizindikiro cha thupi. Mitundu yodziwika bwino ndi iyi:
Mtundu wa magnetic pulse wa Youdaoplaceholder0 : Umapanga chizindikiro cha mafunde a sinusoidal poyambitsa kusintha kwa mphamvu ya maginito kudzera mu disk ya chizindikiro. Uli ndi mtengo wotsika koma umakhala wosavuta kusokonezedwa.
Mtundu wa holo ya Youdaoplaceholder0 : Imatulutsa zizindikiro za mafunde a sikweya pogwiritsa ntchito tsamba loyambitsa, imafuna mphamvu yakunja, ndipo chizindikiro chotulutsa chimakhala chokhazikika ndipo sichikhudzidwa ndi liwiro lozungulira.
Mtundu wa Youdaoplaceholder0 photoelectric : Mpweya woipa umapangidwa podutsa kudzera mu dzenje lowala, molondola kwambiri koma umakhudzidwa mosavuta ndi madontho a mafuta.
Mitundu yonse iyenera kugwira ntchito limodzi ndi sensa ya camshaft position kuti zitsimikizire zizindikiro zogwirizana.
Zotsatira zolakwika
Kulephera kwa sensor kungayambitse:
Nyali ya injini ikayaka, imasonyeza kuti injini ikuvutika kuyatsa, mphamvu yokwanira kapena kulephera kuyatsa.
Kusayatsa bwino ndi nthawi yoperekera mafuta kumachepetsa kugwiritsa ntchito mafuta moyenera komanso kuonjezera mpweya woipa.
Zomwe zimayambitsa mavuto nthawi zambiri ndi kukalamba kwa dera, masensa odetsedwa kapena kulephera kuyika bwino (kuchoka kwachizolowezi ndi 0.2-0.4mm).
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
