Umfanekiso oPhambili weFektri ye-YY251D Leeb Hardness Tester

YY251D Leeb Ukuqina Tester Factory

Inkcazo emfutshane:

I. Imveliso Intshayelelo

Umvavanyi wobulukhuni beLeeb ubona ubulukhuni ngokusekelwe kumgaqo wokulinganisa ubulukhuni beLeeb kunye

inokulinganisa ubunzima bezinto ezahlukeneyo zesinyithi. Umvavanyi usebenzisa iprobe yedijithali ephucukileyo

iteknoloji, ukucutshungulwa kwesignali yedijithali kwenziwa ngqo kwiprobe, nto leyo engaphazanyiswa lula kwaye

inika ukuchaneka okugqwesileyo kovavanyo. Iprobe ine-sensor yecala eyakhelwe ngaphakathi, ethi ngokuzenzekelayo

ilungisa impazamo yokulinganisa kwiindlela ezahlukeneyo zokuchaphazela. Esi sixhobo sineentlobo ngeentlobo ze

iinkqubo zokuqina ezakhelwe ngaphakathi, ezinokuguqulwa phakathi kweLeeb (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) kunye namandla okutsalwa (σb).

yamkela isixhobo sokubetha u-D esifanelekileyo sokuvavanya ubulukhuni bezinto zesinyithi eziqhelekileyo.
