Mohlahlobi oa thatafalo oa bokahohle (Brinell Rockwell Vickers Hardness Tester)

Teko ea ho thatafala ha Universal ha e le hantle ke sesebelisoa sa teko se felletseng se thehiloeng litekanyetsong tsa ISO le ASTM, se lumellang basebelisi ho etsa liteko tsa ho thatafala ha Rockwell, Vickers le Brinell sesebelisoa se le seng. Teko ea ho thatafala ha Universal e lekoa ho latela melao-motheo ea Rockwell, Brinell le Vickers ho fapana le ho sebelisa kamano ea phetoho ea sistimi ea ho thatafala ho fumana boleng bo bongata ba ho thatafala.

Sekala sa boima ba HB Brinell se loketse ho lekanya boima ba tšepe e entsoeng ka tšepe, metsoako e sa sebeliseng tšepe, le litšepe tse fapaneng tse annealed le tse halefisitsoeng. Ha sea lokela ho lekanya disampole kapa mesebetsi e thata haholo, e menyenyane haholo, e tšesaane haholo, 'me e sa lumelle ho kenella ho hoholo holim'a metsi.

Sekala sa thata sa HR Rockwell se loketse: ho leka hlobo, ho lekanya thatafalo ya dikarolo tse phekotsweng ka mocheso o timmeng, o timmeng le o halefisitsweng.

Sekala sa ho thatafala ha HV Vickers se loketse: ho lekanya ho thatafala ha disampole le dikarolo tse nang le dibaka tse nyane le boleng bo hodimo ba ho thatafala, ho thatafala ha dikarolo tse kentsweng kapa dikobo kamora diphekolo tse fapaneng tsa bokahodimo, le ho thatafala ha thepa e tshesane.

Se latelang ke selelekela sa letoto le lecha la liteko tsa ho thatafala ha Universal: le Tester ea ho thatafala ha Universal skrineng se amang.

Ho fapana le teko ea setso ea Universal hardness, teko ea Universal hardness ea moloko o mocha e sebelisa theknoloji ea force sensor le sistimi ea closed-loop force feedback ho nkela mohlala oa ho jara boima sebaka, e leng se etsang hore tekanyo e be bonolo le boleng bo lekantsoeng bo tsitse haholoanyane.
