JBW-300CD computer-controlled automatic ultra-low temperature impact testing machine
1. The impact test machine using liquid nitrogen cooling, the lowest temperature up to -190 ℃ (-190 ℃ ~ -196 ℃ for specific requirements), particularly suitable for the determination of metallic materials impact resistance at low temperature conditions. Metallurgical an important means of testing machinery manufacturing, scientific research and testing, and other units detection material and research and development of new materials.
2. Test machine for the microcomputer automatic control, Yang pendulum, hanging swing, feeding, positioning, shock are electrical, mechanical control sample delivery device equipped with special automatic feed, automatic face orientation sample, sample baked to ensure that the impact time is not more than two seconds, to meet the low temperature metal Charpy impact test method requirements. After the impact of the sample can use the remaining energy automatic Yang pendulum, ready to do the next test. Microcomputer computable display material impact absorbed energy, toughness, the pendulum Yang angle and test averages, and can print average value when the second test data and testing.
3. The machine adopts double support columns, spindles simply supported beam-like support, hanging swing, a reasonable distribution of radial load bearing, especially the large energy impact machines, reduce the spindle deformation and greatly reduce energy loss caused by friction bearings;
4. The use of the standard two-stage gear motor mention hammer, smooth operation;
5. hanging pendulum using cushioning device, hanging pendulum stable;
6. The pendulum three-dimensional design to ensure the combat center accurate precision pendulum moment
7. The impact of knife with screw mounting, easy replacement
8. The Host is equipped with safety pin, and is equipped with a safety net;
9. tester meet the national standard GB / T3803-2002 (test Charpy impact test machine), according to national standard GB / T229-2007 (metal Charpy pendulum impact test methods) of metal material impact test.
