Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Mphete ya pisitoni imasindikiza chipinda choyaka moto kuti mpweya woyaka usalowemo komanso kuti mafuta asathe.
Kugwira ntchito moyenera mphete za pistoni ndizofunikira pa injini.
◆ Wopereka mphete zabwino kwambiri za piston
Ngati mukuyang'ana mphete za pisitoni kapena ntchito za OEM/ODM, mwafika pamalo oyenera. Kaya ndinu wogulitsa zigawo zamagalimoto, mtundu womwe ulipo, wogulitsa, kapena kampani yopanga magalimoto, 1D ndi opanga mphete za piston zomwe zimatha kukwaniritsa zosowa zanu pamtengo wokwanira ndikukupatsani zinthu zabwino.
Mosiyana ndi opanga ena, 1D ili ndi zomangira zingapo zamasilinda zomwe zimagwirizana ndi mitundu yopitilira 1,000 ya injini zamagalimoto. Tili ndi mphamvu zopanga zolimba, kusinthasintha kosintha mwamakonda ndi ntchito yamphamvu ikatha kugulitsa.
◆Kodi mphete za Piston ndi Chiyani?
Nthawi ina, dalaivala aliyense wa novice amafunsa, Kodi mphete ya pistoni ndi chiyani? Kodi mphete ya pistoni imachita chiyani?
Mwachidule, mphete ya pistoni imapanga chisindikizo pakati pa pisitoni ndi khoma la silinda, kuteteza mpweya woyaka kwambiri kuti usalowe mu poto yamafuta. Amayang'aniranso kagwiritsidwe ntchito ka mafuta poletsa mafuta ochulukirapo kulowa muchipinda choyaka ndi kuyaka. Mphete yogwira ntchito bwino ndiyofunikira kuti pakhale mphamvu zambiri za injini komanso kuchita bwino.
◆Kodi mphete ya pistoni imachita chiyani?
Ma pistoni ambiri amagalimoto amakhala ndi mphete zitatu, monga tawonera pansipa.
Mphete yam'mwamba ndi mphete yachiwiri imayang'anira kukanikiza mwamphamvu pakhoma la silinda ndikusindikiza chipinda choyaka kuti mpweya woyaka ulowe ndikutulutsa mafuta.
Mphete yamafuta imachotsa mafuta pakhoma la silinda pamene ikutsikira pansi pa silinda ndikuibwezera ku poto yamafuta. Kuyaka kwina kwamafuta kumakhala kwabwinobwino pakuyaka chifukwa cha mawonekedwe owonda kwambiri amafuta opaka mphete/silinda pakhoma. Zomwe zimapangidwira "zabwinobwino" mafuta, komabe, zimatengera injini.
◆Pamene mphete yabwino ya pisitoni yawonongeka.
Mphete zong'ambika zimapanga kusiyana pakati pa torus ndi khoma la silinda. Pa kuyaka, mpweya woponderezedwa womwe umakankhira pisitoni pansi pa silinda ndikutembenuza crankshaft imatha kuwomberedwa kudzera pa pisitoni ndikutsika pakhoma la silinda ndi poto yamafuta, zomwe zimapangitsa mphamvu zamahatchi komanso kuchita bwino. Kutuluka kungathenso kuipitsa mafuta, kuchepetsa ntchito yake ndi moyo wautumiki.
Clasp ingayambitse zomwezo. Mpweya woyaka kwambiri woyaka kwambiri umaphwanya mafuta, ndikupanga ma depositi a kaboni munjira ya annular. Mafuta opangidwa ndi mafuta amapanganso madipoziti.
Kuchuluka kwa zinyalala kumapangitsa mphete ya pistoni kumamatira mu poyambira m'malo motuluka pisitoni, ndikupanga kusiyana pakati pa mphete ndi khoma la silinda, zomwe zingayambitse kutuluka kwa mpweya ndi kugwiritsa ntchito mafuta.
◆Utsi wabuluu, zoyambira zolimba komanso kutha mphamvu
Zotsatira zoyipa za mphete yoyipa ya pistoni nthawi zambiri zimakhala zosavuta kuziwona. Kugwiritsa ntchito mafuta kwambiri kungapangitse utsi wabuluu kutuluka mupoyipo yotulutsa mpweya, makamaka injini isanatenthedwe komanso mphete za pistoni zikukulirakulira m'masilinda. Kuwotcha mafuta kumatanthauzanso kuti muyenera kudzaza mafuta anu pafupipafupi.
Mphete zosweka kapena zomata zingayambitsenso zovuta kuyambitsa ndikuchepetsa mphamvu zamahatchi.
Injini ikatembenuka, pisitoni imakakamira mafuta / mpweya wosakaniza musanayaka. Komabe, mphete yoyipa imalola kuti mafuta / mpweya utuluke m'chipinda choyaka, ndikuchepetsa kupsinjika kwa injini ndikupangitsa kuti injiniyo ikhale yovuta. Ikangonyamuka ndikuthamanga, kukanika kocheperako kumachotsa mphamvu ku injini yanu.
◆ Ndimotani mmene kupeŵera kulili njira yabwino koposa?
Momwe mungapewere kuvala ndi mphete zophimbidwa ndizofunikira kwambiri kuti muwonjezere mphamvu ya injini, kuchita bwino komanso moyo.
Yambani ndi mafuta apamwamba kwambiri, monga 1D Toyota Series Synthetic mafuta, omwe amatsutsa kuvala ndi kupirira kutentha kwakukulu, kusunga pisitoni kukhala yoyera.
Kachiwiri, tiyenera kusankha mphete zapamwamba za pistoni, monga mphete za pisitoni za 1D, zomwe zingapewe mavuto ambiri monga kusweka ndi kuvala mphete za pistoni.
Ngati mukukayikira kuti mphete ya pistoni yavala kapena kukamira, ganizirani kugwiritsa ntchito mafuta owoneka bwino kwambiri omwe amavomerezedwa ndi Wopanga Zida Zoyambirira (OEM).
Ma Oems ena amapangira ma viscosity osiyanasiyana malinga ndi nyengo yanu (mwachitsanzo, 5W-20 pozizira, 10W-30 pamwamba pa 0ºF). Kugwiritsa ntchito mamasukidwe apamwamba kwambiri kumathandizira kuchepetsa kusiyana pakati pa mphete ndi khoma la silinda.
