Brinell Hardness Tester
Brinell kuomarara tester inofanirwa kushandiswa pakuomarara bvunzo yekukanda.Kune grey iron castings ine zviyo zvakakasharara, mamiriro ekuyedza e3000kg simba uye 10mm bhora anofanira kushandiswa zvakanyanya sezvinobvira.Kana saizi yekukanda idiki, Rockwell hardness tester inogona kushandiswa zvakare.
Iron castings kazhinji ine chimiro chisina kuenzana, zviyo zvakakura, uye zvine kabhoni yakawanda, silicon uye zvimwe zvitsvina kupfuura simbi, uye kuoma kunosiyana munzvimbo diki dzakasiyana kana pane dzakasiyana nzvimbo.Iyo indenter yeBrinell hardness tester ine saizi yakakura uye yakakura indentation nzvimbo, uye inokwanisa kuyera avhareji kukosha kwekuoma kwezvinhu mukati meimwe siyana.Naizvozvo, Brinell kuomarara tester ine yepamusoro bvunzo chokwadi uye kupararira kudiki kwekuoma kwetsika.Iko kuyerwa kwekuomarara kukosha kunomiririra kuoma chaiko kweiyo workpiece.Naizvozvo, iyo Brinell kuomarara tester inoshandiswa zvakanyanya muindasitiri yekuwana.
Rockwell kuoma
Rockwell kuomarara testers zvakare anowanzoshandiswa pakuomarara kuyedzwa kwesimbi yakakandwa.Kune maworkpiece ane zviyo zvakanaka, kana pasina nzvimbo yakakwana yeBrinell kuomarara bvunzo, Rockwell kuomarara bvunzo inogona zvakare kuitwa.Kune pearlitic inogadzika simbi yakakandwa, yakanyungudutswa simbi uye simbi yekukandira, HRB kana HRC chiyero chinogona kushandiswa.Kana iyo nyaya isiri Yakaenzana, kuverenga kwakati kunofanira kuyerwa uye kukosha kweavhareji kunofanira kutorwa.
Shore Hardness Tester
Muzviitiko zvega, kune mamwe ma castings ane mahombe maumbirwo, hazvibvumidzwe kucheka sampuli, uye hazvibvumidzwe kukanda ekuwedzera mabhuroki ekuedzwa kwekuomarara.Panguva ino, kuomarara kuyedzwa kuchasangana nematambudziko.Panyaya iyi, nzira yakajairika ndeyekuyedza kuomarara neinotakurika Shore kuomarara tester pane yakatsetseka pamusoro mushure mekukanda kwapera.Semuenzaniso, muiyo roll standard inoshandiswa zvakanyanya muindasitiri yesimbi, zvinotemerwa kuti Shore kuomarara tester inofanirwa kushandiswa kuyedza kuomarara.
