Kushandiswa kwemuyedzi wekuoma

Muyedzo wekuomarara chishandiso chekuyera kuomarara kwezvinhu. Zvichienderana nezvinhu zvakasiyana-siyana zviri kuyerwa, muyedzo wekuomarara unogona kushandiswa kuminda yakasiyana. Mamwe mayedzo ekuomarara anoshandiswa muindasitiri yekugadzira michina, uye anonyanya kuyera kuomarara kwezvinhu zvesimbi. Zvakadai se: Brinell hardness tester, Rockwell hardness tester, Leeb hardness tester, Vickers hardness tester, microhardness tester, Shore hardness tester, Webster hardness tester nezvimwewo. Mashandisirwo chaiwo evayedzo vekuomarara aya ndeaya anotevera:

Brinell kuomarara muyedzisi:Inonyanya kushandiswa pakuedza kuomarara kwesimbi yakagadzirwa nesimbi yakakandwa ine chimiro chisina kuenzana. Kuomarara kweBrinell kwesimbi yakagadzirwa nesimbi yakakandwa ine grey kwakabatana zvakanaka nekuyedzwa kwekukwesha. Kuedza kuomarara kweBrinell kunogonawo kushandiswa kune simbi dzisina ferrous nesimbi yakapfava. Iyo bhora indenter diki inogona kuyera saizi diki nezvinhu zvakatetepa, uye kuyera mawrkshop ekurapa kupisa uye madhipatimendi ekuongorora mafekitori emafekitori akasiyana-siyana emuchina. Iyo Brinell hardness tester inonyanya kushandiswa pakuongorora zvinhu zvisina kugadzirwa uye zvigadzirwa zvakapedzwa. Nekuda kwekudzika kukuru, haiwanzo shandiswa pakuongorora chigadzirwa chakapedzwa.

 

Rockwell kuomarara muyedzo:Edzai simbi dzakasiyana-siyana dzine simbi dzine simbi nedzisina simbi, edzai kuoma kwesimbi yakadzima, simbi yakadzima uye yakanyoroveswa, simbi yakanyoroveswa, simbi yakaomeswa, mahwendefa ane ukobvu hwakasiyana-siyana, zvinhu zvecarbide, zvinhu zvesimbi dzine upfu, machira ekupisa, ma castings anotonhorera, ma castings anogadziriswa, aruminiyamu alloys, simbi ine bearing, ma plates esimbi akaonda akaomarara, nezvimwewo.

Muedzo weKuomarara kweRockwell wepamusoro:Inoshandiswa kuyedza kuomarara kwesimbi yakatetepa, pombi yemadziro yakatetepa, simbi yakaomeswa nezvikamu zvidiki, alloy yakaoma, carbide, simbi yakaomeswa nekesi, jira rakaomeswa, simbi yakaomeswa, simbi yakadzima uye yakanyoroveswa, simbi yakakandwa inotonhorera, simbi yakakandwa, aruminiyamu, mhangura, magnesium nedzimwe simbi dze alloy.

 

Muedzo wekuomarara weVickers: kuyera zvikamu zvidiki, mapurati esimbi matete, mafoiri esimbi, machira eIC, waya, machira akaonda akaomarara, machira akaiswa electroplated, girazi, zvishongo uye zviumbwa zveceramic, simbi dzeferrous, simbi dzisina ferrous, machira eIC, machira epamusoro, simbi dzakanamirwa; girazi, zviumbwa zveceramic, agate, matombo anokosha, nezvimwewo; kuyedzwa kwekuomarara kwezvikamu zvakakangwa uye kudzima machira akaomarara. Kugadziriswa kwehardware, indasitiri yemagetsi, zvishongedzo zvemould, indasitiri yewachi.

 

Knoopmuyedzi wekuoma:inoshandiswa zvakanyanya kuyera kuomarara kwezviyero zvidiki nezvitete, machira ekupinda pamusoro nezvimwe zviyero, uye kuyera kuomarara kweKnoop kwezvinhu zvakaoma uye zvisina kusimba zvakaita segirazi, ceramics, agate, matombo anokosha ekugadzira, nezvimwewo, chiyero chinoshanda: kurapwa nekupisa, carburization, quenching hardening layer, surface coating, simbi, simbi dzisina ferrous uye zvikamu zvidiki nezvitete, nezvimwewo.

 

Leeb kuomarara muyedzisi:simbi nesimbi yakakandwa, simbi yezvishandiso zve alloy, simbi yakakandwa yegrey, simbi yakakandwa ye ductile, simbi yakakandwa ye aruminiyamu, simbi ye copper-zinc (brass), simbi ye copper-tin (bronze), mhangura yakachena, simbi yakagadzirwa, simbi ye kabhoni, simbi ye chrome, simbi ye chrome-vanadium, simbi ye chrome-nickel, simbi ye chrome-molybdenum, simbi ye chrome-manganese-silicon, simbi yakasimba kwazvo, simbi isina ngura, nezvimwewo.

 

Shsimbimuyedzi wekuoma:Inonyanya kushandiswa kuyera kuomarara kwepurasitiki yakapfava uye rabha yekuomarara yakajairika, senge rabha yakapfava, rabha yekugadzira, maroller erabha ekudhindisa, ma elastomers ethermoplastic, dehwe, nezvimwewo. Inoshandiswa zvakanyanya muindasitiri yepurasitiki, indasitiri yerabha nemamwe maindasitiri emakemikari, kusanganisira kuomarara kwepurasitiki yakaoma uye rabha yakaoma, senge thermoplastic hard resins, zvinhu zvepasi, mabhora ebowling, nezvimwewo. Yakakodzera zvakanyanya kuyerwa kuomarara kwerabha nepurasitiki zvigadzirwa zvakapedzwa panzvimbo.
