| First, the main purpose The test machine is widely used in metal tensile, compression, bending, shear test, can also be used for compressive and flexural tests of cement, concrete and other non-metallic materials. After the addition of a simple aids, can be fasteners, rope, mechanical testing member, is the aerospace sector, research institutes, quality inspection, universities, industrial and mining enterprises ideal for high quality testing equipment. Second, product performance characteristics 1. The control software uses advanced adaptive PID control algorithm, the real three closed-loop digital control. 2. The data collection system consists of four high-precision A / D conversion channel composition, the maximum resolution of 200000, full, regardless of file, or four positions according to user requirements. 3. Use BB, AD, Xilinx and other original brand integrated devices, all-digital design. 4. Built-in large scale CPLD programmable device with high-speed computing power, real-time digital signal processing. 5. Integrated Dual Precision programmable amplifier, digital zero, automatic smooth shifting. 6. Using high quality imported servo valve block, all control signals photoelectric isolation, 24V DC operation, safe and reliable. 7. MaxTest software runs on Windows98 / 2000 / XP operating system; equipped with special test software, test results can be statistical and processing, and then output the various requirements of the test report format and characteristic pattern. 8. Real-time recording, dynamic display test curve. 9. Provide programmable automatic test program, the user can flexibly edit the test procedure according to test requirements. 10. The use of interactive analysis and calculation performance was tested materials, with automatic and manual modes. 11. The test data using standard database management, support batch test. 12. The user can add test methods and corresponding standards required. | model specification | WAW-100B | WAW-300 | WAW-600 | WAW-1000 | | | The maximum test force (kN) | 100 | 300 | 600 | 1000 | | | Test force measurement range (kN) | 2% -5% F.S, 4subsection12510 | | | Accuracy of testing force | ±1% | | | Displacement measurement resolution | 0.01㎜ | | | Deformation measurement accuracy | ± 0.5% F.S | | | Stress rate range | 1MP / S-60MP / S | | | Test strain rate adjustment range | 0.00025 / S-200025 / S | | | Displacement rate control range | 0.5 mm / min-50 mm / min | | | Clamping diameter of round specimen thickness (mm) | 0-15 | 0-15 | 0-30 | 0-40 | | | Clamping diameter of round specimen width (mm) | 40 | 70 | 70 | 120 | | | Testing space (mm) | Stretch | 630 | 650 | 710 | 600 | | | compression | 550 | 550 | 600 | 460 | | | Clamping diameter of round specimen diameter (mm) | Ф6-ф22 | Ф10-ф32 | ф13-ф40 | ф13-ф60 | | | Upper and lower pressure plate size (mm) | ф100 | ф130 | ф180 | 210*210 | | | Bending test support roller spacing (mm) | 30-400 | 30-580 | 30-580 | 30-800 | | | Piston stroke (mm) | 250 | | | Power supply | 380V ± 10%, 50Hz | | | working environment | 10 ℃ ~ 30 ℃, relative humidity≤80% | | | Dimensions (L * W * H) (mm) | Host computer | 730*500*2000 | 905*580*2260 | 905*580*2325 | 1070*850*2530 | Hydraulic pressure source | 600*600*1165 | | | Weight (kg) | 1370 | 2720 | 3020 | 4120 | |
