Muchina wekuyedza kuomarara unonyanya kushandiswa pakuyedza kuomarara kwesimbi yakagadzirwa nesimbi yakakandwa ine chimiro chisina kuenzana. Kuomarara kwesimbi yakagadzirwa nesimbi yakakandwa ine grey kwakabatana zvakanaka nekuyedza kwekusimba. Inogona zvakare kushandiswa kune simbi dzisina ferrous nesimbi isina ferrous, uye bhora diki rinoyera saizi diki nezvinhu zvakatetepa.
Kuomarara kunoreva kugona kwechigadzirwa kuramba kuomeswa kwenzvimbo, kunyanya kushanduka kwepurasitiki, kupinda mukati kana kukwenya, uye chimwe chezviratidzo zvakakosha zvekushanda kwezvinhu zvesimbi. Kazhinji, kuomarara kwacho kwakanyanya, ndiko kuri nani kuramba kuomeswa. Irondedzero yekuyera kupfava nekuomarara kwezvinhu. Zvichienderana nenzira dzakasiyana dzekuyedza, kuomarara kwakakamurwa kuita mhando nhatu. Ngatitarisei chimwe nechimwe chazvo:
Kuomarara kwekukwenya:
Inonyanya kushandiswa kuenzanisa kupfava nekuoma kwezvicherwa zvakasiyana. Nzira yacho ndeyekusarudza tsvimbo ine mugumo mumwe wakaoma uye mumwe wakapfava, kupfuudza chinhu chinofanira kuyedzwa pamwe chete netsvimbo, uye kuona kuoma kwechinhu chinofanira kuyedzwa zvichienderana nenzvimbo yekukwenya. Panyaya yehunhu, zvinhu zvakaoma zvinokwenya kwenguva refu uye zvinhu zvakapfava zvinokwenya kwenguva pfupi.
Kuomarara kwekudzvanya mukati:
Inonyanya kushandiswa pazvinhu zvesimbi, nzira yacho ndeyekushandisa mutoro wakasiyana kuti udzvanye indenter yakatarwa muchinhu chinofanira kuyedzwa, uye kuenzanisa kupfava nekuoma kwechinhu chinofanira kuyedzwa nehukuru hwekukanganisika kwepurasitiki yemuno pamusoro pechinhu chacho. Nekuda kwekusiyana kwe indenter, mutoro uye nguva yekutakura, kune mhando dzakawanda dzekuomarara kwe indentation, kunyanya kusanganisira kuomarara kweBrinell, kuomarara kweRockwell, kuomarara kweVickers uye kuomarara kudiki.
Kuomarara kwekudzoka:
Inonyanya kushandiswa pazvinhu zvesimbi, nzira yacho ndeyekuita kuti nyundo diki yakakosha iwire yakasununguka kubva pakukwirira kwakati kuti irove sampuli yezvinhu zvichaedzwa, uye kushandisa huwandu hwesimba rekumanikidzwa rakachengetwa (rozoburitswa) mumuenzaniso panguva yekurovera (kuburikidza nekudzosa nyundo diki) kuyerwa kwekukwirira kwekusvetuka) kuti uone kuoma kwechinhu chacho.
Chishandiso chekuedza kuomarara chakagadzirwa neShandong Shancai/Laizhou Laihua Testing Instrument rudzi rwechishandiso chekuedza kuomarara, chinoratidza kugona kwechigadzirwa ichi kuramba kupinda kwezvinhu zvakaoma pamusoro pacho. Kune mhando ngani dziripo?
1. Brinell Harness Tester: Inonyanya kushandiswa kuyera kuomarara kwesimbi yakakandwa, simbi, simbi dzisina ferrous uye alloys dzakapfava. Inzira yekuyedza kuomarara kwakanyatsonaka.
2. Rockwell hardness tester: Rockwell hardness tester inogona kuyedza kuoma kwesimbi nekubata sampuro kune rumwe rutivi. Inoshandisa simba remagineti kuti inyevenutse musoro weRockwell hardness tester pamusoro pesimbi, uye haidi kutsigira sampuro.
3. Vickers Hardness Tester: Vickers Hardness Tester chigadzirwa chemhando yepamusoro chinobatanidza optoelectronics nemagetsi. Muchina uyu une chimiro chitsva, wakavimbika, unoshanda zvakanaka uye unonzwisisa. Midziyo yekuongorora kuomarara kweS neKnoop.
4. Brockwell hardness tester: Brockwell hardness tester yakakodzera kuona kuomarara kwesimbi dzesimbi, simbi dzisina ferrous, hard alloys, carburised layers uye chemically treated layers.
5. Muyedzi weMicrohardness: Muyedzi weMicrohardness chishandiso chekuongorora hunhu hwesimbi mumichina, simbi nedzimwe nzvimbo, uye chinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana.
6. Leeb Hardness Tester: Musimboti wayo mukuru ndewekuti muviri weimpact une huremu hwakati unokanganisa pamusoro pemuenzaniso pasi pesimba rekuyedza, uye unoyera kumhanya kweimpact uye kumhanya kweimpact kwemuviri weimpact uri chinhambwe che1 mm kubva pamusoro pemuenzaniso, uchishandisa misimboti ye electromagnetic , voltage inoenderana nekumhanya inokonzerwa.
7. Webster hardness tester: Nheyo yeWebster hardness tester isimbi yakasimba ine chimiro chakati, iyo inodzvanywa pamusoro pemuenzaniso uchishandisa simba rekuyedza remuchirimo.
8. Barcol Hardness Tester: Inyanzvi yekuedza kuomarara kwechinhu ichi. Inodzvanya chinhu chakasiyana mumuenzaniso ichishandiswa nesimba remuchitubu, uye inosarudza kuomarara kwemuenzaniso nekudzika kwechinhu ichi.
