Performance Features
1. Test Machine Mainframe: The mainframe features a closed-frame structure composed of columns, a base, and a crossbeam, providing high frame rigidity, no backlash, and excellent stability. The outer surface of the columns is treated with hard chrome plating. The servo actuator (hydraulic cylinder) is mounted on top and utilizes a double-acting cylinder piston design, offering convenient and flexible specimen clamping adjustments.
2. Key Components: Selected internationally renowned brands include the MOOG servo valve from the USA, DOLI controller from Germany, NACHI hydraulic pump from Japan, Sensotec sensor from the USA, and displacement sensors from MTS, USA.
3. Hydraulic Servo Pump Station: Features leak-free silent technology, stable pressure output without fluctuation, low noise, effective heat dissipation, high filtration accuracy, and automatic protection against pressure overload and excessive oil temperature.
4. Control Method: Employs PID closed-loop control for force, displacement, and deformation, with smooth, disturbance-free switching between any control modes.
5. Testing Software: Compatible with the Windows testing platform, the software works with the control system to conduct various dynamic and static mechanical performance tests, including metal tensile, compression, bending, low-cycle fatigue, and metal fracture tests. It also independently manages test administration, data storage, and test report printing.
6. Test Waveforms: Supports sine, triangular, square, random, sweep, and composite waveforms.
7. Protection Functions: Includes alarm shutdown features for hydraulic blockages, overheating, low fluid level, hydraulic system overload, motor overheating, reaching preset fatigue cycles, and specimen fracture.
