Aluminium alloys yog cov khoom nyiam rau pistons ob qho tib si hauv roj av thiab diesel xyaw vim lawv cov yam ntxwv tshwj xeeb: qis ntom ntom, siab thermal conductivity, cov txheej txheem yooj yim net-shaped fabrication (casting thiab forging), yooj yim machinability, siab ntseeg siab thiab zoo heev recycling yam ntxwv.
Aluminium alloy yog siv hauv piston?
Raws li cov khoom siv rau lub piston, Al (aluminium) alloy uas muaj Si (silicon)yog siv dav.
Puas yog lub nplhaib piston ua los ntawm Aluminium alloy?
Pistons feem ntau yog ua los ntawm a cam khwb cia txhuasrau kev ua tau zoo thiab lub teeb yuag thermal conductivity. Thermal conductivity yog lub peev xwm ntawm cov khoom siv los ua thiab hloov cov cua sov.
Puas yog txhuas piston zoo?
Cov khoom siv feem ntau siv rau lub tsheb pistons yog txhuas vim nws lub teeb yuag, tus nqi qis, thiab lub zog txaus. Txawm hais tias lwm cov ntsiab lus yuav muaj nyob rau hauv me me, lub alloying ntsiab ntawm kev txhawj xeeb nyob rau hauv txhuas rau pistons yog silicon.
Yuav ua li cas hlau siv rau piston?
Pistons yog tsim los ntawm ob qho cov pa roj carbon tsawg lossis aluminium alloys. Lub piston yog raug kub siab, inertia, vibration, thiab kev sib txhuam. Carbon steels txo qhov cuam tshuam ntawm qhov sib txawv thermal expansion ntawm lub piston thiab lub tog raj kheej phab ntsa.
