Lub tshuab ua kom muaj zog Universal yog tiag tiag yog kev soj ntsuam cov qauv ntawm ISO thiab ASTM cov qauv, tso cai rau cov neeg siv pob zeb, cov nyiaj sib tw thiab kev sib tw tawv tawv. Lub tsev pheeb suab pob thoob ntiaj teb yog kuaj raws li Rockwell, brinell, thiab vickers cov ntsiab cai es tsis siv txoj kev sib raug zoo ntawm lub zog kev sib raug zoo kom tau txais ntau txoj kev tawv.
Peb lub hardness nplai haum rau kev ntsuas kev ua haujlwm
HB Brinell hardness nplai yog qhov tsim nyog rau ntsuas lub hardness ntawm cam khwb cia hlau, cov khoom siv tsis sib xws thiab ntau yam. Nws tsis haum rau ntsuas cov qauv lossis cov ua haujlwm uas nyuaj heev, me me, thiab tsis txhob cia cov kev tsis txaus siab loj rau saum npoo.
HR rockwell hardness nplai yog qhov haum rau: Hardness ntsuas ntawm kev sim pwm, quenching, quenching thiab tempering sov-muag.
HV Vickers Hardness Nplai yog tsim nyog rau ntsuas lub hardness ntawm cov qauv lossis cov tawv nqaij tawv ntawm cov khoom me me, thiab lub hardness ntawm cov ntaub ntawv nyias nyias.
Tshiab Ntau Yam ntawm Universal Hardness Tes
Txawv los ntawm cov tso cai lub zog hardness Tester: Tus qauv tshiab University ua haujlwm siv cov qauv hluav taws xob hnyav thiab ntsuas qhov ntsuas tau yooj yim dua.
Kev xaiv cov qib ntawm Automation: tshuab lub taub hau tsis siv neeg Lifting hom, kov tshuaj ntsuam digital zaub hom, khoos phis tawj ntsuas ntsuas
Kev xaiv ntawm kev sim quab yuam, hardness zaub hom thiab hardness daws teeb meem
Rockwell: 60kgf (588.4n), 100kgf (980.7n), 150kgf (1471n)
Nto Rockwell: 15Kg (197.1n (197.1n), 3094.2n (294.2n), 45kg (491.3n) (yeem)
Brinell: 5, 6.25, 6.625, 25, 30,5, 189.5, 306,9, 980.7, 1880.7, 1839n)
Vickers: 5, 10, 20, 30, 50, 100, 129.03, 990.3, 990.7, 1176.8n)
Hardness tus nqi ntawm hom: Kov screen zaub rau rockwell, kov tshuaj ntsuam, khoos phis tawm rau brinell thiab vickers.
Hardness daws teeb meem: 0.1hr (rockwell); 0.1hb (BRinnell); 0.1hv (vickers)
