Caterpillar pistons qhia tshwj xeeb tshaj yog cov qauv hauv kev xaiv cov khoom siv thiab cov txheej txheem tsim khoom, qhia txog kev sib xyaw ntawm cov khoom siv tes ua thiab thev naus laus zis. Cov khoom siv tseem ceeb ntawm lub cev yog qhov tshwj xeeb siab - lub zog aluminium alloy, tsis yog cov khoom siv zoo tib yam, tab sis ib qho kev tsim kho kom zoo los ntawm kev tshawb fawb thiab kev sim ntau yam.
Aluminium alloys yog lub teeb yuag thiab muaj cov thermal conductivity zoo, ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig. Qhov no yog zoo li forging ib tug robust tsis tau lub teeb yuag "cov cuab yeej" rau lub piston, tso cai rau nws mus tau yooj yim nrog ntau yam hnyav ua hauj lwm tej yam kev mob thaum lub sij hawm siab - khiav ceev nyob rau hauv lub cav.
Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, Caterpillar siv ib tug series ntawm advanced technologies. Cov txheej txheem piston casting siv precision casting tshuab, uas ua kom cov qauv siab heev ntawm qhov raug thiab qhov zoo. Txhua qhov kev nthuav dav yog sculpted precisely, zoo li ib tug craftsman meticulously sculpting ib tug ua hauj lwm ntawm kos duab, kom ntseeg tau tias txawm kev nyuaj siab faib thoob plaws hauv lub piston thiab txhim kho nws lub zog thiab kev cia siab rau.
Ib txheej txheej tshwj xeeb yog siv rau ntawm lub piston nto. Cov txheej no ua haujlwm zoo li "tiv thaiv zaj duab xis" rau lub piston, txhim kho nws cov hnav tsis kam thiab corrosion kuj, txo cov kev sib txhuam coefficient ntawm lub piston thiab lub tog raj kheej phab ntsa, txo qis zog poob, thiab txhim kho lub cav roj kev lag luam. Qhov no txhais tau hais tias lub cav khiav zoo dua, thiab roj efficiency yog qhov zoo dua.
