Hauv cov txheej txheem ntawm kev sim qhov nyuaj, cov khoom siv tawv txheem yog qhov tseem ceeb. Yog li, lub luag haujlwm ntawm cov khoom siv tawv yog dab tsi, thiab lawv raug faib ua pawg li cas?
I.Cov khoom siv tawv feem ntau ua peb lub luag haujlwm hauv kev sim tawv: calibrate cov hardness testers, ua kom muaj kev sib piv cov ntaub ntawv, thiab cob qhia cov neeg ua haujlwm.
1. Thaum siv lub tshuab ntsuas qhov nyuaj mus sij hawm ntev, tej zaum yuav muaj kev hloov pauv hauv cov sensors lossis cov qauv kho tshuab ntawm lub tshuab. Yog li ntawd, peb siv cov blocks txheem uas muaj cov nqi qhov nyuaj paub los xyuas lossis kho qhov tseeb ntawm lub tshuab ntsuas qhov nyuaj. Txhua lub block hardness muaj daim ntawv lo nrog tus nqi qhov nyuaj; kev sim nrog lub block hardness ua ntej kev kuaj pom raug cai tuaj yeem kho qhov ntsuas ntawm lub tshuab ntsuas qhov nyuaj, tshem tawm qhov yuam kev ntawm cov cuab yeej, xyuas kom meej tias cov ntaub ntawv ntsuas ua tau raws li cov qauv xav tau, xyuas kom meej tias lub tshuab ntsuas qhov nyuaj ua haujlwm tau zoo, thiab txiav txim siab sai sai seb lub tshuab ntsuas qhov nyuaj puas ua haujlwm zoo.
2. Los ntawm kev ntsuas cov khoom tawv nrog cov lus qhia sib koom ua ke, qhov sib piv ntawm cov txiaj ntsig xeem tuaj yeem ua tiav ntawm cov neeg ntsuas tawv sib txawv thiab cov neeg soj ntsuam sib txawv. Los ntawm kev muab cov ntaub ntawv qhia txog tus qauv nrog cov nqi tawv paub, cov qauv xeem nyob rau hauv cov neeg ntsuas tawv sib txawv thiab cov xwm txheej ntsuas sib txawv tau koom ua ke.
3. Cov khoom siv tawv txheem kuj tseem siv rau hauv kev cob qhia cov neeg ua haujlwm hauv chaw soj nstuam lossis cov chaw tsim khoom kom txhim kho kev ua haujlwm zoo.
Lawv cov nqi hardness raug calibrated los ntawm cov koom haum authoritative, featuring traceability, accuracy, thiab stability. Cov khoom siv ntawm cov hardness blocks zoo ib yam li cov workpiece uas yuav tsum tau kuaj (xws li hlau, yas, thiab lwm yam), uas tuaj yeem phim cov txheej txheem ntsuas hardness sib txawv (Brinell, Rockwell, Vickers, thiab lwm yam).
II.Kev faib tawm ntawm cov khoom siv tawv yog raws li ntau yam ntsuas tawv, hom khoom siv, thiab ntau yam ntawm cov nqi tawv. Cov hom feem ntau yog raws li nram no:
1. Kev faib tawm los ntawm Txoj Kev Ntsuas Hardness
Qhov no yog txoj kev faib tawm feem ntau siv, sib raug rau cov hom ntsuas qhov nyuaj:
Rockwell Hardness Blocks (HRC, HRB, thiab lwm yam): Sib xws nrog Rockwell hardness testers, siv rau kev sim hardness niaj hnub ntawm cov khoom siv hlau.
Brinell Hardness Blocks (HBW): Sib xws nrog Brinell hardness testers, tsim nyog rau kev ntsuas cov hlau uas tsis muaj zog lossis cov ntaub ntawv uas muaj cov noob ntxhib.
Vickers Hardness Blocks (HV): Sib xws nrog Vickers hardness testers, muaj qhov tseeb siab, thiab tuaj yeem ntsuas cov workpieces nyias, cov khoom me me, thiab cov txheej tawv.
Shore Hardness Blocks (HS): Sib xws nrog Shore hardness testers, feem ntau yog siv rau kev sim hardness ntawm cov workpieces loj lossis cov khoom siv tsis txav chaw.
Leeb Hardness Blocks (HL): Sib xws nrog Leeb hardness testers, tsim nyog rau qhov chaw kuaj thiab tsis ua puas tsuaj.
2. Kev faib tawm los ntawm cov khoom siv
Cov Khoom Siv Hlau Hardness: Xws li cov hlau carbon, hlau alloy, hlau stainless, tooj liab alloy, thiab lwm yam, uas npog cov kev xav tau ntawm feem ntau cov khoom siv hlau hauv kev lag luam.
Cov Khoom Siv Uas Tsis Yog Hlau: Xws li cov yas, roj hmab, thiab cov khoom siv ceramic hardness, uas sib xws nrog kev ntsuas qhov nyuaj ntawm cov khoom siv uas tsis yog hlau.
3. Kev faib tawm los ntawm Qib Kev Tseeb
Qib Txheem (Qib 1): Siv rau kev ntsuas cov ntsuas qhov nyuaj, nrog rau qhov tseeb ntawm tus lej thiab kev taug qab mus rau cov qauv ntsuas hauv tebchaws.
Qib Ua Haujlwm (Qib 2): Siv rau kev sib piv kev sim txhua hnub thiab txheeb xyuas qhov ruaj khov ntawm cov cuab yeej, ua tau raws li qhov xav tau ntawm kev sim ntau lawm.
Thaum yuav cov khoom siv tawv, nws yog ib qho tsim nyog los phim hom khoom siv ntsuas tawv, qhov nyuaj ntawm cov khoom siv uas yuav tsum tau kuaj, thiab qhov tseeb. Kev ntsuas yuav tsum ua raws li cov ntsiab cai ntawm "tib yam qauv, tib yam mob, thiab kev ua haujlwm txheem" kom ntseeg tau tias qhov tseeb thiab kev taug qab ntawm cov nqi ntsuas.
