Nazi mfundo zazikulu zokhudzana ndi kufunika kwa pistoni

Pistoni ndi gawo lofunikira kwambiri pama injini oyatsira mkati, chifukwa imagwira ntchito zingapo zofunika pakugwira ntchito kwa injiniyo. Nazi mfundo zazikuluzikulu za kufunikira kwa pistoni:

1. Kusintha kwa Mphamvu:Pistonikuthandizira kutembenuka kwa mpweya wothamanga kwambiri kukhala mphamvu zamakina. Panthawi yoyaka, mpweya wowonjezereka umakankhira pisitoni pansi, kutembenuza mphamvu yamankhwala mumafuta kukhala ntchito yamakina.

2. Chisindikizo ndi Kuponderezedwa: Ma pistoni amapanga chisindikizo ndi makoma a silinda, zomwe zimawalola kuti azipaka mafuta osakaniza mpweya kapena mpweya wotulutsa mpweya mkati mwa chipinda choyaka moto. Kusindikiza koyenera kumatsimikizira kuyaka bwino komanso kupewa kutaya mphamvu ndi kuponderezana.

3. Kusamutsa Mphamvu:Pistonitumizani mphamvu yopangidwa ndi mpweya wokulitsa ku ndodo yolumikizira ndipo pamapeto pake ku crankshaft. Mphamvu imeneyi ndi imene imatembenuza crankshaft, yomwe imasintha kayendedwe ka pisitoni kuti ikhale yozungulira.

4. Kutentha Kwambiri: Ma pistoni amatha kutentha kwambiri chifukwa cha kuyaka. Amakhala ndi mayendedwe ozizirira ndipo amapangidwa kuchokera kuzinthu zokhala ndi matenthedwe abwino kuti azitha kutentha bwino ndikupewa kutenthedwa kapena kuwonongeka.

5. Kukhathamiritsa Kulemera: Ma pistoni amapangidwa kuti akhale opepuka pamene akukhalabe ndi mphamvu ndi kupirira. Kuchepetsa kulemera kwa pisitoni kumathandizira kukonza magwiridwe antchito a injini, kuchepetsa mphamvu, komanso kulola kuti injini ikhale yothamanga kwambiri.

6. Mphete za pisitoni: Ma pistoni amaphatikiza mphete za pistoni zomwe zimapereka chisindikizo chotsetsereka pakati pa pisitoni ndi makoma a silinda. Mphetezi zimathandiza kuti pakhale kuponderezedwa koyenera, kuletsa kuphulika kwa mpweya, komanso kumathandizira kuyanika bwino powongolera filimu yamafuta pamakoma a silinda.

7. Magwiridwe A Injini: Mapangidwe, mawonekedwe, ndi zinthu za pisitoni zimakhudza magwiridwe antchito a injini, monga kutulutsa mphamvu, mphamvu yamafuta, ndi mpweya. Zatsopano zamapangidwe a piston zimafuna kukulitsa kuyaka bwino, kuchepetsa kukangana, komanso kupititsa patsogolo magwiridwe antchito a injini.

Mwachidule, ma pistoni ndi zigawo zofunika kwambiri zamainjini oyatsira mkati, omwe ali ndi udindo wotembenuza mphamvu, kusunga kuponderezana, kusamutsa mphamvu, kutaya kutentha, komanso kukopa magwiridwe antchito a injini. Kupanga kwawo koyenera ndi magwiridwe antchito ndikofunikira kuti injini igwire bwino ntchito komanso yodalirika.
