Tus ntsuas qhov hardness yog qhov ntsuas los ntsuas qhov hardness ntawm ib yam khoom. Raws li kev ua los ntawm cov nyom, nws tuaj yeem muab faib ua ob hom: ib qho kev sim ua cov tawv tawv yooj yooj yim thiab ib lub tshuab kuaj cov tawv tawv. Lub tshuab kuaj phom hardness muaj qhov sib txawv hardness testers sib txawv raws li kev faib tawm.
1. Cov Kev Ntsuas Hluav Taws Xob los ntawm lub npe
(1) Ntug dej hardness tester: siv los txiav txim Lub Shore hardness tus nqi ntawm ferrous thiab tsis-ferrous hlau;
(2) Brinell hardness tester: siv rau kev ntsuas Brinell hardness tus nqi ntawm workpieces muaj qhov nyuaj dua;
(3) Leeb hardness tester: siv rau tag nrho cov hlau, yooj yim rau qhov nyuaj nkag los lossis txwv qhov chaw kuaj chaw;
(4) Shore hardness tester: siv los ntsuas lub Shore hardness tus nqi ntawm cov khoom siv roj hmab;
(5) Rockwell hardness tester: Rockwell hardness tus nqi ntsuas rau workpieces xws li cov hlau cam khwb cia (6) Barcol hardness tester: siv los ntsuas qhov Barcol hardness tus nqi ntawm cov iav fiber ntau dua cov khoom yas.
(7) Vickers hardness tester: ntsuas ntawm Vickers hardness tus nqi rau cov haujlwm ua haujlwm nyuaj dua;
(8) Webster hardness tester: siv rau kev ntsuas Vickers hardness tus nqi ntawm aluminium alloy khoom;
2. Cov ntsuas kuaj cov tawv tawv yog cais raws hom
(1) Ntau txoj kev kuaj hardness;
(2) Benchtop hardness tester;
(3) Portable hardness tester (portable hardness tester): rau kev teeb tsa cov tshuab lossis lub chaw sib dhos ruaj khov, thiab lwm yam.
(4) Ultrasonic hardness tester: siv rau pwm thiab nplooj ntawv; saum npoo tawv tawv hniav thiab zog, thiab lwm yam.
3. Hardness tester los ntawm cov khoom siv
(1) Roj hmab hardness tester: siv los txiav txim qhov nyuaj ntawm vulcanized roj hmab thiab cov khoom yas;
(2) Kev ntsuas cov tawv hlau rau Rockwell hardness kev soj ntsuam ntawm cov hlau nyuaj, carbon hlau, alloy hlau, cam khwb cia hlau, hlau tsis muaj hlau, thiab lwm yam.;
(3) Txiv hmab txiv ntoo hardness tester: siv los ntsuas qhov nyuaj ntawm ntau cov txiv hmab txiv ntoo xws li kua, pear, dib thiab txiv tsawb.
