Mphete za pisitoni
Mfundo Zofunika Kwambiri
Mphete za Pistoni: Zinthu zofunika kwambiri zomwe zimatseka zipinda zoyaka moto, zimawongolera mafuta, komanso zimasamutsa kutentha.
Mphete Zitatu: Mphete iliyonse imagwira ntchito yapadera—kutseka kupanikizika, kusamutsa kutentha, ndi kuwongolera mafuta.
Zizindikiro Zolephera: Kutaya mphamvu, kugwiritsa ntchito mafuta mopitirira muyeso, utsi wabuluu, kapena kulephera kugwira ntchito.
Mayankho Aukadaulo: Zipangizo zapamwamba kwambiri komanso uinjiniya wolondola zimathandizira kulimba komanso kugwira ntchito bwino m'mikhalidwe yovuta kwambiri.
Kodi Mphete za Piston Ndi Chiyani?
Mphete za pistoni ndi mipiringidzo yozungulira yachitsulo yomwe imayikidwa mozungulira ma pistoni mu injini zoyatsira mkati. Zimagawanika kuti zilole kukula ndi kufupika panthawi yogwira ntchito. Kawirikawiri zimapangidwa ndi chitsulo chosungunuka, chitsulo, kapena zitsulo zamakono, mphete zamakono za pistoni zimapangidwa kuti zipirire kutentha kwambiri, kupanikizika, ndi kukangana.
Ntchito Zofunika Kwambiri
Kutseka Chipinda Choyaka: Kuteteza kutayikira kwa mpweya panthawi yoyaka, kuonetsetsa kuti mphamvu yamagetsi ikugwira ntchito bwino kwambiri.
Kusamutsa Kutentha: Tembenuzani kutentha kuchokera pa pistoni kupita ku khoma la silinda, kuti mupewe kutentha kwambiri.
Kuwongolera Mafuta: Kuwongolera kufalikira kwa mafuta pakhoma la silinda kuti muchepetse kukangana pamene mukuletsa mafuta ochulukirapo kulowa m'chipinda choyaka moto.
Nchifukwa chiyani ma pistoni ali ndi mphete zitatu?
Ma injini ambiri amagwiritsa ntchito mphete zitatu za pistoni, iliyonse yokonzedwa bwino kuti igwire ntchito inayake:
Mphete Yopondereza Yapamwamba: Imapirira kupsinjika kwakukulu ndi kutentha, imatseka mpweya woyaka kuti injini igwire bwino ntchito.
Mphete Yachiwiri Yopondereza: Imathandizira mphete yapamwamba potseka mpweya ndipo imathandizanso kuyeretsa kutentha.
Mphete Yowongolera Mafuta (Mphete Yokokera): Imachotsa mafuta ochulukirapo pakhoma la silinda ndikubwezera mafuta ku crankcase, kuchepetsa kugwiritsidwa ntchito ndi kutulutsa mpweya.
Kodi chimachitika n'chiyani ngati mphete za piston zalephera?
Zizindikiro Zodziwika za Kulephera:
Kutaya mphamvu ya injini: Kuthina kwa mpweya wotuluka kumachepetsa mphamvu ya kuyaka.
Kugwiritsa ntchito mafuta mopitirira muyeso: Mphete zosweka zimathandiza mafuta kulowa m'chipinda choyaka moto.
Utsi wabuluu wotulutsa utsi: Mafuta oyaka amapangitsa kuti mpweya wotulutsa utsi ukhale wabuluu.
Kuchuluka kwa mpweya woipa: Mphete zolephera zimapangitsa kuti mpweya woipa wa hydrocarbon uchuluke.
Injini yalephera kugwira ntchito: Kukanikizana kosafanana kumasokoneza kayendedwe ka kuyaka.
Zotsatira Zanthawi Yaitali: Kunyalanyaza mphete za piston zomwe zatha kungayambitse kuwonongeka kosatha kwa khoma la silinda, kulephera kwa catalytic converter chifukwa cha kuipitsidwa kwa mafuta, komanso kukonzanso injini modula kapena kusintha injini.
