Nigute ushobora kugenzura niba ikizamini gikomeye gikora bisanzwe?
1.Ikizamini cyo gukomera kigomba kugenzurwa byuzuye rimwe mukwezi.
2.
3.
4. Mugihe cyo gukoresha indimu ya diyama, birakenewe kugenzura hejuru yubuso bwa indenter rimwe mumwaka. Nyuma ya buri gupima, indenter igomba gusubizwa mumasanduku yihariye yo kubika.
Ikizamini cyo kugerageza gukomera:
Usibye kwitondera bidasanzwe mugihe ukoresheje ibizamini bitandukanye bigoye, hariho ibibazo bimwe na bimwe bikunze kwitabwaho, biri kurutonde hepfo:
1. Ikizamini cyo gukomera ubwacyo kizatanga ubwoko bubiri bwamakosa: rimwe ni ikosa ryatewe no guhindura no kugenda kw'ibice byaryo; ikindi ni ikosa ryatewe nuburemere bukomeye burenze igipimo cyagenwe. Kubwikosa rya kabiri, igeragezwa rikomeye rigomba guhindurwa hamwe nibisanzwe mbere yo gupimwa. Kuri kalibrasi y'ibisubizo bya Rockwell igerageza, itandukaniro ryujuje ibisabwa muri ± 1. Agaciro ko gukosora karashobora gutangwa kubiciro bihamye hamwe nibitandukaniro muri ± 2. Iyo itandukaniro riri hanze yurwego rwa ± 2, birakenewe ko uhindura kandi ugasana ibizamini byo gukomera cyangwa guhindura ubundi buryo bwo gupima ubukana.
Buri gipimo cyubukomezi bwa Rockwell gifite ibikorwa bifatika, bigomba guhitamo neza ukurikije amabwiriza. Kurugero, mugihe ubukana burenze HRB100, igipimo cya HRC kigomba gukoreshwa mugupima; mugihe ubukana buri munsi ya HRC20, igipimo cya HRB kigomba gukoreshwa mugupima. Kuberako ubunyangamugayo nubukangurambaga bwibizamini bikomeretsa bikennye mugihe igipimo cyikizamini kirenze, kandi agaciro gakomeye ntikwiye, ntabwo gakwiriye gukoreshwa. Ubundi buryo bwo gupima ubukana nabwo bufite ibipimo ngenderwaho bihuye. Igice gisanzwe gikoreshwa muguhindura igeragezwa ryikigereranyo ntigishobora gukoreshwa kumpande zombi, kuko ubukana bwuruhande rusanzwe hamwe ninyuma ntabwo byanze bikunze ari bimwe. Mubisanzwe biteganijwe ko guhagarika bisanzwe byemewe mugihe cyumwaka umwe uhereye umunsi wa kalibrasi.
2. Mugihe usimbuye indenter cyangwa anvil, witondere gusukura ibice byitumanaho. Nyuma yo kubihindura, gerageza inshuro nyinshi hamwe nicyuma cyicyitegererezo cyubukomere runaka kugeza igihe agaciro gakomeye kabonetse kabiri kumurongo nikimwe. Ikigamijwe ni ugukora indenter cyangwa anvil hamwe nigice cyo guhuza imashini yipimisha kanda cyane kandi muburyo bwiza, kugirango bitagira ingaruka kubisubizo byibizamini.
3. Nyuma yo gupima ubukana bwahinduwe, mugihe utangiye gupima ubukana, ingingo yambere yikizamini ntabwo ikoreshwa. Kubwoba bwo guhura nabi hagati yicyitegererezo na anvil, agaciro gapimwe ntabwo kukuri. Nyuma yingingo ya mbere igeragejwe kandi igeragezwa ryikomeye riri muburyo busanzwe bwo gukora, icyitegererezo kirageragezwa kumugaragaro kandi agaciro gapimwe kapimwe.
4.
5. Kubice byipimisha bifite imiterere igoye, hagomba gukoreshwa amakariso yuburyo bumwe, kandi arashobora kugeragezwa nyuma yo gukosorwa. Igice cyizamini kizengurutse gishyirwa muri V-shusho yo kugerageza.
6. Mbere yo gupakira, genzura niba ikiganza cyo gupakira gishyizwe mumwanya wo gupakurura. Mugihe cyo gupakira, ibikorwa bigomba kuba byoroshye kandi bihamye, kandi ntukoreshe imbaraga nyinshi. Nyuma yo gupakira, ikiganza cyo gupakira kigomba gushyirwa mumwanya wo gupakurura, kugirango wirinde igikoresho kuba munsi yumutwaro igihe kirekire, bigatera ihinduka rya plastike kandi bigira ingaruka kubipimo.
Vickers, Rockwell gukomera
Gukomera: Nubushobozi bwibikoresho byo kurwanya ihindagurika rya plastike yaho, kandi bipimwa cyane nuburyo bwo kwerekana.
Icyitonderwa: Indangagaciro zikomeye ntizishobora kugereranwa nizindi, kandi zirashobora guhindurwa gusa mumeza yo kugereranya gukomera.
Muri 2019, Shandong Shancai Testing Instrument Co., Ltd yinjiye muri komite ishinzwe tekinike yo gupima imashini yipimisha kandi yitabira gushyiraho ibipimo bibiri byigihugu

Mu 2021, Shandong Shancai yagize uruhare mu iyubakwa ry’umushinga wogupima ibyuma byikora kuri interineti byimiyoboro ya moteri yo mu kirere, bigira uruhare mu nganda zo mu kirere kavukire.
