Product details
WAW-300D microcomputer controlled electro-hydraulic servo universal testing machine (six columns) isAn important instrument and equipment for testing the physical properties, mechanical properties, process performance, structural seismic strength, and internal and external defects of various materials and their products in various environments and simulated states. It is possible to conduct tensile, compressive, bending, shear and other types of tests on metal or non-metal materials according to corresponding standards. Performance indicators such as tensile strength, yield strength, specified non proportional elongation strength, elastic modulus, etc. of the tested material can be obtained. It is possible to achieve closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, constant rate strain, etc. It is also possible to conduct process qualification performance verification tests on materials or products.
1. The host adopts a streamlined appearance design, with the oil cylinder placed below. The strength distribution of each component is reasonable, and the overall combination is scientific, atmospheric, and beautiful. It has independent painting technology and can customize the painting effect and color according to customer needs to match the customer's on-site environment;
2. The coaxiality between the centerline of the upper and lower clamping heads and the tensile axis of the testing machine is 8% (significantly better than the national standard requirement of less than 15%);
3. The clamping of the sample is driven by hydraulic pressure. The upper and lower crossbeams are equipped with built-in clamping small oil cylinders, which are safer, more reliable, have a longer lifespan, do not leak oil, and have a beautiful appearance compared to external clamping oil cylinders.
4. The clamping force of the sample increases with the increase of the test force, and the sample is firmly clamped;
5. The hydraulic system adopts servo closed-loop control and is equipped with highly responsive imported servo valves, which can achieve fully automatic and precise control;
The hydraulic system design fully considers energy saving, reliability, safety, and environmental protection. Adopting a differential pressure throttling speed control servo servo system, the system's working pressure automatically adjusts with changes in load, reducing system heating and saving energy. All components are made of environmentally friendly components;
7. The high-pressure gear pump is directly connected to the motor, with a compact structure, smooth operation, and noise levels below 70dB;
8. Through random calibration, the experiment is not affected by external forces, ensuring the accuracy of the experimental process and parameters. The force direction of the tension, compression and other test sensors is consistent. Calibration, simple and convenient;
9. Choose high-quality high-pressure hoses and fittings to ensure no leakage occurs;
10. Configure a high-performance intelligent fully digital controller, using fully digital PID regulation, equipped with independent servo amplifiers, measurement and control software, and data acquisition and processing software, which can achieve multiple closed-loop control modes such as constant rate test force, constant rate cylinder displacement, and constant rate strain, and can smoothly switch between different control modes;
11. Configure a multifunctional testing software package for the measurement and control system, using VXDs high-speed data acquisition technology to achieve high-speed acquisition of multi-channel data; Can analyze and process test results according to different test method requirements, with human-machine interaction programming control function, convenient for adding new test standards; It has powerful graphic operation functions, which can display and draw experimental curves and display experimental data in real time. It has functions such as curve scaling, graphic enlargement, and clipping, as well as cursor following display. Capable of storing complete test curves and test data; Capable of outputting single test reports and printing batch test reports;
12. It has a network interface that enables data networking and remote control functions;
13. Safety protection device: It has protection functions such as test force overload, over setting, power-off, and piston reaching the limit position.
