Kuomarara kwepombi yesimbi zvinoreva kugona kwechinhu kurwisa deformation pasi pesimba rekunze. Iko kuoma ndeimwe yezviratidzo zvakakosha zvekushanda kwezvinhu.
Mukugadzirwa uye kushandiswa kwepombi dzesimbi, kutsunga kwekuoma kwavo kunokosha zvikuru. Hukukutu hwemapombi esimbi hunogona kuyerwa nevaiedza vakasiyana-siyana vakaita seRockwell, Brinell, uye Vickers vanogadzirwa neLaizhou Laihua Testing Instrument Factory, iyo inogona kugadzirwa sezvinodiwa. Nzira huru dzekuyera dzinosanganisira dzinotevera:
1. Rockwell kuomarara nzira yekuyedza
Iyo Rockwell kuomarara bvunzo parizvino ndiyo inonyanya kushandiswa nzira, pakati peiyo HRC yechipiri chete kune Brinell kuomarara HB mune yesimbi pombi standard. Inoyera kudzika kweiyo indentation uye inogona kushandiswa kuyera zvinhu zvesimbi kubva zvakapfava zvakanyanya kusvika zvakanyanya kuoma. Zviri nyore kupfuura nzira yekuyedza yeBrinell.
2. Brinell kuomarara nzira yekuongorora
Iyo Brinell kuomarara nzira yekuyedza zvakare inoshandiswa zvakanyanya mumunda weindasitiri. Inoshandiswa zvakanyanya musimbi isina musono pombi zviyero. Kuoma kwezvinhu zvinowanzoratidzwa nedhayamita indentation. Iyo intuitive uye yakanakira, asi haishande kune yakaoma kana kutetepa simbi pombi.
3. Vickers kuoma kwekuedza nzira
Iyo Vickers kuomarara bvunzo inoshandiswawo zvakanyanya. Iyo ine mabhenefiti makuru eiyo Brinell uye Rockwell nzira dzekuyedza, asi inokunda yavo yekutanga kusakosha. Inokodzera kuomarara kuyedzwa kwezvinhu zvakasiyana-siyana, asi haina kukodzera masampuli ane madhayamita madiki. Haisi nyore seye Rockwell yekuyedza nzira uye haiwanzo shandiswa musimbi pombi zviyero.
