United Test Instrumented Charpy Impact Testing Machine-1

JBW-H Series Instrumented Charpy Impact Testing Machine Introduction JBW-H series instrumented impact tester is adopts advanced foreign technology and cooperate with China National Engineering & Physical research institute to developed a new products. Through measuring the impact value, collect and analysis the impact process data, figure energy curve, then supply details data for engineers to study and anaylsis material character. This tester is mainly consist of automatically high and low temperature device (optional), auto-feeding system, and impact tester loadframe, can be used test, analysis the accuracy material anti-impact performance. Tester is controlled by computer, rising pendulum, hang pendulum, impact, stop all controlled by PC. Adopt data collection system, change the voltage signal to digital signal, add data storage and PC, to transfer collected data to impact load - time, impact load-displacement, displacement- time, energy- time etc. curve. Vivid illustrate the material under loading and deformation process to break. Features ★ Comply with GB/T19748-2005, ISO 14556 : 2000(E), ASTM E23 etc.; ★ Loadframe base and leading column integrated design, overall process, with high stiffness, and improve test stability; ★ Impact axis adopt Charpy type, reasonable the radial direction load, maximum decrease energy loss caused by the bearing friction; ★ Adopt two level standard deceleration motor to rise the pendulum, rising and hang pendulum adopt hydraulic buffer to smooth the action; ★ Pendulum is round shape swing type, ensure the strike center accuracy, and precision pendulum moment. ★ Can achieve parameter of Impact velocity, impact time, impact energy, absorb energy, displacement, crack forming energy, crack extension energy, yield load, yield time, peak load, time of peak load, More details, please contact sales person for detail quotation!
