Kuomarara kweVickers inzira yekuratidza kuomarara kwezvinhu zvakakurudzirwa naRobert L. Smith naGeorge E. Sandland wekuBritain muna 1921 paVickers Ltd. Iyi imwe nzira yekuedza kuomarara inotevera nzira dzekuongorora kuomarara kweRockwell neBrinell.
1 Nheyo yeVickers hardness tester:
Muchina wekuedza kuomarara weVickers unoshandisa mutoro we49.03 ~ 980.7N kudzvanya chinhu chedhaimani chine mativi mana chine kona ye136° pamusoro pechinhu chacho. Mushure mekuchichengetedza kwenguva yakatarwa, yera gomba rakatenderedzwa. Kureba kwemutsetse, wobva waverenga kukosha kwesimba reVickers zvichienderana nefomura.
2. Rodha yekushandiswa kwemhando yepamusoro:
01: Muchina wekuedza kuomarara weVickers une mutoro we49.03 ~ 980.7N wakakodzera kuyera kuomarara kwezvishandiso zvakakura uye zvikamu zvakadzika zvepadenga;
02: Kuomarara kweVickers, mutoro wekuyedza <1.949.03N, kwakakodzera kuyerwa kwekuomarara kwezvishandiso zvitete, pamusoro pematurusi kana machira;
03: Kuomarara kweMicro-Vickers, mutoro wekuyedza <1.961N, kwakakodzera kuyerwa kwekuomarara kwesimbi foils uye zvidimbu zvitete zvakanyanya.
Pamusoro pezvo, ine Knoop indenter, inogona kuyera kuomarara kweKnoop kwezvinhu zvakaoma uye zvisina kusimba zvakaita segirazi, zviumbwa zvedongo, agate, uye matombo anokosha ekugadzira.
3 Mabhenefiti eVickers hardness tester:
1) Kuyera kwakafara, kubva kusimbi dzakapfava kusvika kune vanoedza kuomarara zvakanyanya kusvika kusimbi dzakaoma zvakanyanya, uye kuyera kwacho kunotangira pahuwandu hwesimba reVickers hushoma kusvika kuzviuru zvitatu.
2) Kupinda mukati kudiki uye hakukuvadzi workpiece. Kunogona kushandiswa pakuedza kuomarara kweworkpiece dzine pamusoro padzo dzisingakanganise.
3) Nekuda kwesimba rayo diki rekuyedza, simba diki rekuyedza rinogona kusvika 10g, saka inogona kuona zvimwe zvinhu zvitete nezvidiki zvebasa.
4 Zvakashata zveVickers hardness tester: Kana tichienzanisa nenzira dzeBrinell neRockwell dzekuedza hardness, Vickers hardness test ine zvinodiwa kuti nzvimbo yebasa ive yakatsetseka, uye mamwe maworkpiece anoda kukweshwa, izvo zvinotora nguva uye zvinoda basa guru; kugadzirisa hardness tester yakanyatsojeka uye haina kukodzera kushandiswa mumaworkshop kana panzvimbo yacho. Inonyanya kushandiswa muma laboratories.
5 Vickers kuomarara tester nhevedzano
1) Muedzo weVickers wekuomarara unodhura
2) Dhijitari yekubata skrini yekubata Vickers yakaomarara
3) Muedzo wekuomarara weVickers unongoerekana waitwa otomatiki
