Niaj hnub no, cov cuab yeej ntsuas Leeb hardness feem ntau yog siv rau kev tshuaj xyuas ntau yam khoom siv hauv tsev. Cia kuv qhia qee qhov kev paub dav dav txog cov cuab yeej ntsuas Leeb hardness.
Kev kuaj qhov nyuaj ntawm Leeb yog ib txoj kev kuaj qhov nyuaj tshiab uas tau tsim los ntawm Swiss Dr. Leeb hauv xyoo 1978.
Lub hauv paus ntsiab lus ntawm Leeb hardness test: Ib lub cev cuam tshuam nrog qee qhov hnyav raug cuam tshuam rau ntawm qhov chaw ntawm cov qauv hauv qab qee lub zog xeem, thiab qhov ceev cuam tshuam thiab qhov ceev rov qab ntawm lub cev cuam tshuam 1 hli ntawm qhov chaw ntawm cov qauv raug ntsuas. Siv lub hauv paus ntsiab lus electromagnetic, qhov cuam tshuam thiab Leeb hardness tus nqi yog xam los ntawm qhov sib piv ntawm qhov ceev rov qab, uas yog ib txoj kev sim dynamic. (Koj tuaj yeem nrhiav daim duab ntawm lub hauv paus ntsiab lus no hauv Is Taws Nem)
Yog li hom workpiece twg yog Leeb hardness tester haum rau?
Leeb hardness tester yog lub tshuab ntsuas hardness ntau yam uas tuaj yeem hloov pauv Rockwell, Brinell, Vickers, thiab Shore hardness scales tau yooj yim. Txawm li cas los xij, nws muaj cov kev cai rau cov workpiece. Tsis yog txhua qhov workpieces tuaj yeem siv Leeb hardness scale. Kev ntsuas hardness tester los hloov lub rooj zaum hardness tester. (Qhov no muaj lub interface hloov pauv rau Leeb hardness tester)
Raws li txoj cai ntsuas ntawm Leeb hardness tester thiab nws qhov yooj yim nqa tau, nws feem ntau yog tsim rau (tab sis tsis txwv rau) kev ntsuas ntawm cov haujlwm hauv qab no:
Cov khoom siv kho tshuab lossis cov khoom sib dhos tas mus li uas tau teeb tsa thiab tsis tuaj yeem tshem tawm
Cov khoom ua haujlwm uas muaj qhov chaw sim me me xws li cov pwm qhov (koj yuav tsum tau them sai sai rau qhov loj ntawm qhov chaw thaum yuav khoom)
Cov khoom ua haujlwm loj uas xav tau kev tshuaj xyuas sai thiab ua ke
Kev tshuaj xyuas qhov tsis ua haujlwm ntawm cov hlab ntsha siab, cov tshuab hluav taws xob turbine thiab lwm yam khoom siv.
Kev tswj qhov nyuaj ntawm cov kab ntau lawm rau cov bearings thiab lwm yam khoom
Cov khoom siv kho tshuab lossis cov khoom sib dhos tas mus li uas tau teeb tsa thiab tsis tuaj yeem rhuav tshem tau
Cov khoom ua haujlwm uas muaj qhov chaw sim me me xws li cov pwm qhov (koj yuav tsum tau them sai sai rau qhov loj ntawm qhov chaw thaum yuav khoom)
Cov khoom ua haujlwm loj uas xav tau kev tshuaj xyuas sai thiab ua ke
Kev tshuaj xyuas qhov tsis ua haujlwm ntawm cov hlab ntsha siab, cov tshuab hluav taws xob turbine thiab lwm yam khoom siv
Kev tswj qhov nyuaj ntawm cov kab ntau lawm rau cov bearings thiab lwm yam khoom
Kev tshuaj xyuas cov khoom siv tag nrho thiab kev sib txawv sai ntawm cov khoom siv hlau hauv tsev
Kev tswj xyuas zoo thaum lub sijhawm tsim cov khoom ua haujlwm kho cua sov
Cov khoom siv Leeb hardness testers uas siv ntau tshaj plaws hauv peb lub tuam txhab suav nrog cov hauv qab no:
HLN110 Hom Tshuab Luam Ntawv Leeb Hardness Tester
HL200 Xim hom Leeb Hardness Tester
HL-150 Cwj mem hom Leeb Hardness Tester
Lub sijhawm tshaj tawm: Cuaj hlis-14-2023
