Piston pas nrig quenching cov khoom siv kho cua sov

Quenching yog tib txoj hauv kev txhawm rau txhim kho kev pabcuam lub neej thiab kev ua haujlwm ntawm cov pas nrig piston. Cov khoom siv ultrasonic quenching ua quenching cua sov kho ntawm lub piston pas nrig, feem ntau yog cua sov qhov kub mus rau 800-900 ℃, thiab ces txias sai heev, kom lub hardness ntawm lub workpiece twb ho txhim kho thiab ua tau raws li cov kev xav tau ntawm nws ua hauj lwm.

Lub piston pas nrig yog quenched los ntawm ultrasonic quenching rauv. Thaum lub cub tawg ultrasonic quenches piston pas nrig, nws yuav tsis tsim suab nrov thiab plua plav, uas zoo heev txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm thiab ib puag ncig kev cob qhia, uas ua tau raws li cov kev cai ntawm kev tiv thaiv ib puag ncig.
