Mphete za Piston

Chithunzi Chowonetsedwa ndi mphete za Piston
  • Mphete za Piston

Kufotokozera Kwachidule:

Mphete za Piston ndizofunikira kwambiri pamainjini amagalimoto ndi makina osiyanasiyana. Amapangidwa kuti apange chisindikizo cholimba mkati mwa silinda, chomwe chimakhala chofunikira kwambiri pakuponderezedwa bwino ndi kuyaka kwamafuta. Mphetezi nthawi zambiri zimapangidwa kuchokera kuzinthu zomwe zimapereka kukhazikika komanso kusinthasintha, kuonetsetsa kuti zitha kupirira kupsinjika ndi kutentha kwambiri mkati mwa injini ndikusunga kukwanira bwino.

Ntchito yayikulu ya mphete za Piston ndikuwongolera kayendedwe ka mpweya ndikuletsa kutayikira kwa mpweya woyaka kupitilira pisitoni kulowa mu crankcase. Amathandiziranso kugawa mafuta opaka pamakoma a silinda, omwe ndi ofunikira kuti achepetse kugundana ndi kutha. Mphete za Piston zimapezeka mumapangidwe ndi zida zosiyanasiyana kuti zigwirizane ndi mitundu ina ya injini ndi momwe zimagwirira ntchito, zomwe zimawapangitsa kukhala gawo lofunikira kwambiri pakugwira ntchito kwa injini yonse komanso moyo wautali.

Zofunika Kwambiri

Mphete za pisitoni: Zinthu zofunika kwambiri zomwe zimasindikiza zipinda zoyaka moto, zimawongolera mafuta, ndikusintha kutentha.

Mphete Zitatu: Mphete iliyonse imakhala ndi ntchito yosiyana—kusindikiza, kutumiza kutentha, ndi kuwongolera mafuta.

Zizindikiro Zolephera: Kutaya mphamvu, kugwiritsa ntchito mafuta kwambiri, utsi wabuluu, kapena moto wolakwika.

Mayankho aukadaulo: Zida zapamwamba kwambiri komanso uinjiniya wolondola zimatsimikizira kulimba komanso kugwira ntchito muzovuta kwambiri.

 

Kodi mphete za Piston ndi chiyani?

Mphete za pisitoni ndi magulu ozungulira achitsulo omwe amaikidwa mozungulira ma pistoni mumainjini oyatsira mkati. Amagawidwa kuti alole kufalikira ndi kutsika panthawi ya ntchito. Nthawi zambiri amapangidwa ndi chitsulo chonyezimira, chitsulo, kapena ma aloyi apamwamba, mphete zamakono za pistoni zimapangidwira kuti zipirire kutentha kwambiri, kupanikizika, ndi kukangana.

Ntchito Zoyambira

Kusindikiza Chipinda Choyaka: Pewani kutuluka kwa gasi pakuyaka, kuwonetsetsa kuti magetsi atuluka kwambiri.

Kutumiza Kutentha: Kutentha kuchokera pa pisitoni kupita ku khoma la silinda, kupewa kutenthedwa.

Kuwongolera Mafuta: Yang'anirani kagawidwe ka mafuta pakhoma la silinda kuti muchepetse mikangano ndikuletsa mafuta ochulukirapo kulowa mchipinda choyaka.

Chifukwa Chiyani Ma Pistoni Ali Ndi mphete Zitatu?

Ma injini ambiri amagwiritsa ntchito mphete zitatu za pistoni, iliyonse yokonzedwa kuti igwire ntchito inayake:

Mphete Yoponderezedwa Yapamwamba: Imapirira kupanikizika kwambiri komanso kutentha, kusindikiza mipweya yoyaka kuti iwonjezere mphamvu ya injini.

Mphete Yachiwiri Yophatikizika: Imathandizira mphete yapamwamba pakusindikiza mipweya komanso imathandizira kutulutsa kutentha.

Mphete Yoyang'anira Mafuta (Scraper Ring): Imachotsa mafuta ochulukirapo pakhoma la silinda ndikubwezeretsa mafuta ku crankcase, kuchepetsa kumwa komanso kutulutsa mpweya.

Chimachitika ndi Chiyani Pamene mphete za Piston Zikalephera?

Zizindikiro zodziwika bwino za kulephera:

Kutayika kwa mphamvu ya injini: Kupopera kotayikira kumachepetsa kuyaka bwino.

Kugwiritsa ntchito mafuta mopitirira muyeso: Mphete zong’ambika zimalola mafuta kulowa m’chipinda choyaka moto.

Utsi wotulutsa buluu: Mafuta oyaka amatulutsa utoto wonyezimira mu mpweya wotuluka.

Kuchuluka kwa mpweya: mphete zomwe zalephera kumathandizira kutulutsa mpweya wambiri wa hydrocarbon.

Injini imasokonekera: Kuphatikizika kosafanana kumasokoneza kayendedwe ka kuyaka.

Zotsatira Zanthawi Yaitali: Kunyalanyaza mphete za pisitoni zomwe zatha kungayambitse kuwonongeka kwa khoma la silinda, kulephera kosinthira kwamphamvu chifukwa cha kuipitsidwa kwamafuta, komanso kukonzanso kwa injini zamtengo wapatali kapena kusinthidwa.
