Leeb Hardness Tester
Tam sim no, Leeb hardness tester tau dav siv hauv kev sim hardness ntawm castings.Leeb hardness tester txais lub hauv paus ntsiab lus ntawm dynamic hardness tester thiab siv computer technology kom paub txog cov miniaturization thiab electronicization ntawm hardness tester.Nws yog qhov yooj yim thiab siv tau yooj yim, kev nyeem ntawv yog qhov yooj yim dua, thiab cov txiaj ntsig kev sim tuaj yeem hloov pauv tau yooj yim rau hauv Brinell hardness qhov tseem ceeb, yog li nws tau txais tos dav.
Ntau cov castings yog nruab nrab-rau-loj workpieces, qee qhov hnyav ob peb tons, thiab tsis tuaj yeem kuaj ntawm lub rooj zaum saum tawv tawv tester.Qhov tseeb hardness xeem ntawm castings tsuas yog siv cais cam khwb cia rods los yog xeem blocks txuas rau castings.Txawm li cas los xij, tsis yog qhov ntsuas bar lossis qhov ntsuas ntsuas tsis tuaj yeem hloov lub workpiece nws tus kheej.Txawm hais tias nws yog tib lub cub tawg ntawm cov hlau molten, cov txheej txheem casting thiab kev kho cua sov yog tib yam.Vim tias qhov sib txawv loj ntawm qhov loj, qhov cua sov, tshwj xeeb tshaj yog qhov txias txias, yuav txawv.Nws yog ib qho nyuaj rau ua kom ob qho tib si hardness.Vim li no, ntau tus neeg muas zaub nyiam ntau dua thiab ntseeg hauv hardness ntawm workpiece nws tus kheej.Qhov no yuav tsum tau portable precision hardness tester los ntsuam xyuas hardness ntawm castings.Lub Leeb hardness tester daws qhov teeb meem no, tab sis nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas qhov ua tiav ntawm lub workpiece thaum siv Leeb hardness tester.Leeb hardness tester muaj qhov yuav tsum tau ua rau qhov roughness ntawm lub workpiece.
Brinell Hardness Tester
Brinell hardness tester yuav tsum tau siv rau kev sim hardness ntawm castings.Rau grey hlau castings nrog coarse nplej, qhov kev xeem ntawm 3000kg quab yuam thiab 10 hli pob yuav tsum tau siv ntau li ntau tau.Thaum qhov loj me me, Rockwell hardness tester kuj tseem siv tau.
Hlau castings feem ntau muaj cov qauv tsis sib xws, cov nplej loj dua, thiab muaj cov pa roj carbon ntau, silicon thiab lwm yam impurities dua li cov hlau, thiab qhov hardness yuav txawv ntawm qhov sib txawv me me los yog ntawm cov ntsiab lus sib txawv.Lub indenter ntawm Brinell hardness tester muaj qhov loj dua thiab qhov loj dua indentation cheeb tsam, thiab tuaj yeem ntsuas qhov nruab nrab ntawm cov khoom hardness nyob rau hauv ib qho chaw.Yog li ntawd, Brinell hardness tester muaj qhov ntsuas qhov tseeb dua thiab qhov sib txawv me me ntawm cov nqi hardness.Qhov ntsuas hardness tus nqi yog ntau tus neeg sawv cev ntawm qhov tseeb hardness ntawm lub workpiece.Yog li ntawd, Brinell hardness tester yog dav siv hauv kev lag luam foundry.
Rockwell hardness
Rockwell hardness testers kuj feem ntau siv rau kev sim hardness ntawm cam khwb cia hlau.Rau cov khoom ua haujlwm nrog cov nplej zoo, yog tias tsis muaj cheeb tsam txaus rau Brinell hardness test, Rockwell hardness test kuj tseem tuaj yeem ua.Rau pearlitic malleable cam khwb cia hlau, chilled cam khwb cia hlau thiab hlau castings, HRB los yog HRC nplai yuav siv tau.Yog tias cov ntaub ntawv tsis sib npaug, ntau qhov kev nyeem yuav tsum tau ntsuas thiab qhov nruab nrab tus nqi yuav tsum tau muab coj los siv.
Ntug Hardness Tester
Nyob rau hauv ib tus neeg mob, rau qee qhov castings nrog cov duab loj, nws tsis raug tso cai los txiav cov qauv, thiab nws tsis raug tso cai los nrum ntxiv cov blocks rau kev kuaj hardness.Lub sijhawm no, kev sim hardness yuav ntsib teeb meem.Rau cov ntaub ntawv no, txoj hauv kev yog los ntsuas qhov nyuaj nrog lub portable Shore hardness tester ntawm tus nto tom qab lub casting tiav.Piv txwv li, nyob rau hauv cov txheej txheem yob dav siv nyob rau hauv kev lag luam metallurgical, nws tau teev tseg tias Shore hardness tester yuav tsum tau siv los ntsuas qhov hardness.
