从China供应商批发进口Wti-W300c Low Temperature Impact Testing Machine — FOB条款

1.Applications ans features-torsion testing machine ? This impact testing machine combines low temperature test and impact test in one machine. ? Adopts auto sample feeding device so that sample will be sent to do impact test once low temperature test is finished. This is done within 4 seconds to improve test precision and working efficiency. ? All the procudures (sample cooling, temperature holding, temperature adjust, raise pendulum, locate pendulum, sample sending, sample locating and impact) are electric auto control ? After breakage of sample, pendulum will raise with rest energy to prepare for the next test. Its super performance is suitable to the lab doing continuous low temperature impact test and to the metallurgy and engineering works doing large number of low temperature test. ? Test method: ASTM E23, EN 10045, ISO 148, ISO 83, etc. 2.Main specifications-torsion testing machine 1 Impact engergy 150J 300J 2 Pendulum pre-raising angle 150° 3 Distance between pendulum center to impact point(sample center) 750mm 4 Impact speed 5.2m/s 5 Span of impact specimen support 40mm 6 round corner of nipper jaw R(1.0-1.5)mm 7 round corner of impacting edge R(2.0-2.5)mm 8 impact knife thickness 16mm 9 cooling mode liquid nitrogen refrigeration 10 Sample box capacity 10 pcs 11 Temperature range room tempeature- minus 196?
