Asalin gwajin taurin Vickers
Taurin Vickers misali ne na wakiltar taurin abu wanda Robert L. Smith da George E. Sandland suka gabatar a shekarar 1921 a Vickers Ltd. Wannan wata hanyar gwajin taurin abu ce da ke bin hanyoyin gwajin taurin Rockwell da Brinell.
Ka'idar gwajin taurin Vickers:
Mai gwajin taurin Vickers yana amfani da nauyin 49.03~980.7N don danna lu'u-lu'u mai siffar murabba'i mai kusurwa 136 ° a saman kayan. Bayan riƙe shi na tsawon lokacin da aka ƙayyade, ana ƙididdige ƙimar taurin Vickers ta hanyar auna tsawon diagonal na indentation da amfani da dabarar.
Jerin aikace-aikacen kaya na nau'ikan Vickers guda uku masu zuwa (micro Vickers):
Na'urar gwajin taurin Vickers mai nauyin 49.03 ~ 980.7N ta dace da auna taurin manyan kayan aiki da kuma zurfin yadudduka na saman.
Ƙarancin taurin Vickers, nauyin gwaji <1.949.03N, ya dace da auna taurin kayan aiki masu siriri, saman kayan aiki, ko rufin da aka shafa;
Taurin Micro Vickers, nauyin gwaji <1.961N, ya dace da auna tauri na foil ɗin ƙarfe da kuma yadudduka na saman da suka yi siriri sosai.
Bugu da ƙari, yana da na'urar shigar da Knoop, yana iya auna taurin Knoop na kayan da suka karye da tauri kamar gilashi, yumbu, agate, da duwatsu masu daraja na wucin gadi.
Amfanin gwajin taurin Vickers:
1. Tsarin aunawa yana da faɗi, daga ƙarfe na software zuwa ƙarfe masu ƙarfi, kuma ana iya gano shi, daga ƙimar taurin Vickers kaɗan zuwa dubu uku.
2. Layin shiga ƙarami ne kuma baya lalata kayan aikin, wanda za'a iya amfani dashi don gwada tauri akan kayan aikin da ba za'a iya lalata su ba akan saman kayan aikin.
3. Saboda ƙaramin ƙarfin gwaji, ƙaramin ƙarfin gwaji zai iya kaiwa 10g, wanda zai iya gano wasu sirara da ƙananan kayan aiki.
Rashin amfani da na'urar gwajin taurin Vickers:
Idan aka kwatanta da hanyoyin gwajin tauri na Brinell da Rockwell, gwajin tauri na Vickers yana da buƙatu don santsi a saman kayan aikin. Wasu kayan aikin suna buƙatar gogewa, wanda ke ɗaukar lokaci da ƙoƙari.
Gwajin taurin Vickers daidai yake kuma ba su dace da amfani da su a wuraren bita ko a wurin ba, kuma galibi ana amfani da su a dakunan gwaje-gwaje.
Jerin gwajin taurin kai na Shandong Shancai Vickers (hoto na Wang Songxin)
1. Mai gwajin taurin tattalin arziki Vickers
2. Nunin dijital da allon taɓawa na Vickers mai gwajin taurin kai
3. Gwajin taurin Vickers mai cikakken atomatik
