JBDW-300Y microcomputer control automatic temperature impact testing machine
JBDW-300Y microcomputer control automatic temperature impact testing machine for the performance of impact resistance of metal materials under dynamic load inspection, metallurgical machinery and other units of the necessary testing equipment, also new materials research unit indispensable test instrument.
Testing machine microcomputer automatic control, Yang pendulum, hanging swing, feeding, positioning, shock and temperature adjustment settings are electrical, mechanical control devices equipped with special automatic send samples to send samples, sample automatic face orientation. Specimens released to impact time is not more than 2 seconds, meet the requirements of low-temperature metal Charpy impact test method in the sample after the impact of the remaining energy can be used to automatically Yang placed and do the next test preparation, high work efficiency. Computer computable display material impact energy, impact toughness, the pendulum Yang angle and test average value, and can print when the second test data and test the average temperature of the temperature indicator can fully meet the requirements of national standards required GB229-2007.
