Cov yam ntxwv thiab daim ntawv thov ntawm Rockwell hardness tester

Kev kuaj ntawm Rockwell hardness tester yog ib qho ntawm peb txoj kev siv ntau tshaj plaws ntawm kev kuaj qhov nyuaj.

Cov yam ntxwv tshwj xeeb yog raws li nram no:

1) Rockwell hardness tester yooj yim dua rau kev khiav lag luam dua li Brinell thiab Vickers hardness tester, tuaj yeem nyeem ncaj qha, coj kev ua haujlwm siab.

2) Piv nrog rau Brinell hardness test, qhov indentation me dua li ntawm Brinell hardness tester, yog li nws tsis muaj kev puas tsuaj rau qhov chaw ntawm cov workpiece, uas yog qhov tsim nyog dua rau kev kuaj pom cov khoom tiav ntawm cov cuab yeej txiav, pwm, cov cuab yeej ntsuas, cov cuab yeej, thiab lwm yam.

3) Vim yog lub zog ua ntej ntawm Rockwell hardness tester, qhov cuam tshuam ntawm qhov tsis sib xws me ntsis ntawm qhov nyuaj ntawm qhov nyuaj yog tsawg dua li ntawm Brinell thiab Vickers, thiab nws yog qhov tsim nyog dua rau kev tsim khoom loj ntawm kev ua haujlwm thermal thiab metallurgical thiab kev tshuaj xyuas cov khoom tiav lossis tiav.

4) Nws muaj qhov me me ntawm superficial Rockwell hardness tester hauv kev sim, tuaj yeem siv los sim qhov nyuaj ntawm cov txheej tawv tawv lossis txheej txheej txheej.
