The Universal hardness tester ha e le hantle ke lisebelisoa tsa tlhahlobo tse felletseng tse thehiloeng ho litekanyetso tsa ISO le ASTM, tse lumellang basebelisi ho etsa liteko tsa ho thatafala tsa Rockwell, Vickers le Brinell lisebelisoa tse tšoanang.Mohlahlobi oa boima ba bokahohle o lekoa ho latela melao-motheo ea Rockwell, Brinell, le Vickers ho e-na le ho sebelisa kamano ea phetoho ea tsamaiso ea boima ho fumana litekanyetso tse ngata tsa boima.
Likala tse tharo tse thata tse loketseng ho lekanya li-workpieces
Sekala sa boima ba HB Brinell se loketse ho metha ho thatafala ha tšepe e entsoeng ka tšepe, li-alloys tse se nang ferrous, le litšepe tse fapa-fapaneng tse halefileng le tse futhumetseng.Ha e loketse ho lekanya lisampole kapa li-workpieces tse thata haholo, tse nyane haholo, tse tšesaane haholo, 'me ha li lumelle li-indent tse kholo holim'a metsi.
Sekala sa boima ba HR Rockwell se loketse: tekanyo ea boima ba hlobo ea liteko, ho tima, ho tima le ho futhumatsa likarolo tse kentsoeng mocheso.
HV Vickers hardness scale e loketse ho lekanya boima ba lisampole le likarolo tse nang le libaka tse nyenyane le boleng bo phahameng ba ho thatafala, ho thatafala ha lihlopha tse kentsoeng kapa liphahlo ka mor'a liphekolo tse fapaneng tsa holim'a metsi, le ho thatafala ha lisebelisoa tse tšesaane.
Lethathamo le lecha la li-universal hardness testers
E fapane le teko ea boima ba bokahohleng e tloaelehileng: moloko o mocha oa "hardness tester" oa moloko o mocha o sebelisa theknoloji ea sensor ea matla le mokhoa oa ho fana ka maikutlo a koetsoeng ho nka sebaka sa mokhoa oa ho laola boima ba 'mele, ho etsa hore tekanyo e be bonolo le boleng bo lekantsoeng bo tsitsitse haholoanyane.
Tekanyo ea boikhethelo ea othomathike: mofuta oa ho phahamisa hlooho ka mochini, mofuta oa pontšo ea dijithale skrineng, mofuta oa ho lekanya komporo
