Raws li peb txhua tus paub, txhua txoj kev sim qhov nyuaj, txawm tias Brinell, Rockwell, Vickers lossis lub tshuab ntsuas Leeb hardness, muaj nws cov kev txwv thiab tsis muaj hwj chim. Rau cov khoom ua haujlwm loj, hnyav thiab tsis sib xws xws li qhov tau pom hauv qhov piv txwv hauv qab no, ntau txoj kev sim tam sim no siv cov tshuab ntsuas Leeb hardness portable los tswj lawv qhov nyuaj.
Txoj kev ntsuas dynamic ntawm Leeb hardness tester muaj ntau yam uas cuam tshuam rau nws qhov tseeb ntawm qhov nyuaj: xws li: cov khoom siv elastic modulus, pob taub hau noj, workpiece nto roughness, curvature radius, nto hardened txheej tob, thiab lwm yam. Piv nrog rau cov txheej txheem ntsuas static ntawm Brinell, Rockwell thiab Vickers, qhov yuam kev loj dua. Yog tias qhov nyuaj xav tau qhov tseeb siab dua, peb yuav tsum xaiv lub hardness tester li cas?
Hom khoom siv hnyav no thaum lub sijhawm sim cov khoom siv hardness tester, ua ntej kev sim thauj khoom thiab tshem tawm cov khoom siv hardness tester, thiab tshem tawm cov khoom siv hardness tester yuav ua rau muaj kev ua haujlwm ntau heev hauv cov txheej txheem ua haujlwm, yog li peb yuav xaiv cov khoom siv hardness tester li cas? Cov hauv qab no pom zoo kom siv cov khoom siv hardness tester nrog lub taub hau tsa kom ua tiav tag nrho cov txheej txheem sim. Raws li qhia hauv qab no:
Cov kev daws teeb meem kev sim qhov nyuaj no tuaj yeem ua tiav Rockwell hardness testing / Vickers thiab Brinell hardness testing raws li cov qauv kev sim qhov nyuaj (GB / T 231.1, GB / T 4340.1, ISO6507, ISO6508, ASTM E18, thiab lwm yam), thiab ua tau raws li kev sim siab thiab kev tsim khoom zoo ntawm cov khoom siv hnyav.
Lub taub hau tsis siv neeg nqa lub tshuab ntsuas qhov nyuaj muaj lub rooj ua haujlwm ruaj khov, uas txo qhov yuam kev los ntawm lub hau ntswj thiab kev nqa ntawm lub rooj ua haujlwm mus rau qhov ntsuas qhov nyuaj. Lub rooj ua haujlwm loj thiab tuaj yeem tuav cov khoom siv hnyav loj. Kev ntsuas ib lub pob khawm txo qhov yuam kev kuaj thiab kev ua haujlwm ntawm lub tshuab ntsuas, uas yooj yim thiab ceev.
