Iyo yekuomarara tester inonyanya kushandiswa kuomarara bvunzo yesimbi yakaumbwa uye simbi yakakandwa ine isina kuenzana chimiro.Kuomarara kwesimbi yakaumbwa uye grey cast iron ine kunyorerana kwakanaka pamwe nekuyedza bvunzo.Inogona zvakare kushandiswa kune isiri-ferrous simbi uye nyoro simbi, uye diki dhayamita bhora indenter inogona kuyera diki saizi uye zvitete zvinhu.
Kuomarara kunoreva kugona kwechinhu kurwisa deformation yenzvimbo, kunyanya deformation yepurasitiki, indentation kana makwara, uye ndeimwe yeakakosha maitiro ekuita zvesimbi zvinhu.Kazhinji, iyo yakakwirira kuoma, zviri nani kupfeka kuramba.Indekisi yekuyera kupfava nekuoma kwezvinhu.Zvinoenderana neakasiyana maitiro ekuyedza, kuomarara kwakakamurwa kuva marudzi matatu.Ngatitarisei kune imwe neimwe yadzo:
Scratch hardness:
Inonyanya kushandiswa kuenzanisa kupfava uye kuoma kwemaminerari akasiyana.Nzira yacho ndeyekusarudza tsvimbo ine mugumo wakaoma uye imwe mugumo yakapfava, kupfuudza zvinhu kuti zviedzwe pamwe chete netsvimbo, uye kuona kuoma kwezvinhu kuti zviedzwe maererano nechinzvimbo chekukwenya.Mukutaura kwehunhu, zvinhu zvakaoma zvinogadzira makwara marefu uye zvinhu zvakapfava zvinogadzira zvikwambo zvipfupi.
Press-in kuomarara:
Inonyanya kushandiswa kumidziyo yesimbi, iyo nzira ndeye kushandisa imwe mutoro kudzvanya iyo yakatsanangurwa indenter muzvinhu kuti zviedzwe, uye enzanisa kupfava uye kuoma kwezvinhu kuti zviedzwe nehukuru hwenzvimbo yepurasitiki deformation pamusoro zvinhu.Nekuda kwekusiyana kweindenter, kuremerwa uye kuremerwa kwenguva, kune akawanda marudzi ekuomarara kwemukati, kunyanya kusanganisira Brinell kuomarara, Rockwell kuomarara, Vickers kuomarara uye microhardness.
Rebound kuoma:
Inonyanya kushandiswa kumidziyo yesimbi, iyo nzira ndeyekugadzira nyundo diki diki inodonha yakasununguka kubva kune imwe nzvimbo kureba kuti ibate sampu yechinhu chinofanirwa kuongororwa, uye kushandisa huwandu hwesimba rekumanikidza rakachengetwa (uye rozoburitswa) mumuenzaniso panguva kukanganisa (kuburikidza nekudzoka kwesando diki) svetuka urefu hwechiyero) kuona kuoma kwechinhu.
Iyo yekuomarara tester inogadzirwa naShandong Shancai/Laizhou Laihua Testing Instrument imhando ye indentation kuomarara kwekuedza chiridzwa, icho chinoratidza kugona kwechinhu kuramba kupinzwa kwezvinhu zvakaoma mukati mayo.Marudzi mangani aripo?
1. Brinell Hardness Tester: Inonyanya kushandiswa kuyera kuoma kwesimbi yakakandwa, simbi, isina-ferrous simbi uye soft alloys.Iyo yakanyanya-chaiyo yekuomarara nzira yekuyedza.
2. Rockwell hardness tester: Rockwell hardness tester inogona kuedza kuoma kwesimbi nekubata muenzaniso kune rumwe rutivi.Iyo inotsamira pane magineti simba kushambadza iyo Rockwell kuomarara bvunzo musoro pamusoro pesimbi, uye haidi kutsigira sampuli.
3. Vickers Hardness Tester: Vickers Hardness Tester is high-tech chigadzirwa chinobatanidza optoelectronics uye magetsi.Muchina wacho unovhengana muchimiro, une kuvimbika kwakanaka, kushanda uye intuitiveness.S uye Knoop kuomarara kwemidziyo yekuyedza.
4. Brockwell hardness tester: The Brockwell hardness tester inokodzera kuona kuoma kwesimbi, nonferrous metal, hard alloys, carburized layers uye makemikari akaiswa zvidimbu.
5. Microhardness tester: Microhardness tester inyanzvi yekuongorora maitiro ezvigadzirwa zvesimbi mumashini, metallurgy nemamwe maindasitiri, uye inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana.
6. Leeb Hardness Tester: Musimboti wayo mukuru ndewekuti muviri une huremu une humwe huremu unokanganisa pamusoro pesample pasi peimwe simba rekuyedza, uye inoyera kukanganiswa kwevelocity uye rebound velocity yemuviri wekuchinja uri chinhambwe che1 mm kubva sampuli pamusoro, uchishandisa electromagnetic misimboti, voltage inoenderana nekumhanya inonyengerwa.
7. Webster hardness tester: Nheyo yeWebster hardness tester indenter yakaoma yesimbi ine imwe chimiro, iyo inomanikidzwa mukati meiyo sampuli pasi pechitubu chekuongorora simba.
8. Barcol Hardness Tester: Ndiyo indentation yakaoma tester.Inodzvanya indenter chaiyo mumuenzaniso pasi pekuita kwechitubu chakajairwa, uye inosarudza kuoma kwemuenzaniso nekudzika kweiyo indentation.
