The performance characteristics of the static load anchor test machine:

1. Using high-precision amplifier and A/D converter, the whole process is not classified, the first-level accuracy, the measurement range is 2%-100%FS, and the digital real-time display of load, displacement, peak load, and displacement

degree;

2. Fully computerized automatic control, using PID closed-loop control strategy to achieve load control;

3. Use the latest dual-servo pump control technology to realize the load closed-loop control function;

4. It adopts 650T oil source and 300T oil source dual servo pump oil source, which can be used in combination or alone. The anchor static load test in the laboratory can use only 650T oil source alone, and the friction loss of the anchor port

650T oil source and 300T oil source dual-servo pump oil source software automatically switches. In the construction site anchorage friction loss test, 300T oil source can be used alone, which is easy to carry;

5. Using 650T and 300T dual load sensors, measurement accuracy: ≤±1%;

6. Load measurement accuracy range: 2%-100%FS;

7. Pressure measurement accuracy: ≤±1%;

8. Pressure measurement accuracy range: 5%-100%FS;

9. Pressurizing speed control accuracy: ≤±5%;

10. Pressure holding control accuracy: ≤±0.01MPa;

11. Real-time display of load-time, load-displacement and displacement-time curves;

12. The control steps can be freely edited according to the test requirements;

13. At the end of the test, the test result data can be automatically calculated and saved, and the user can query and print the test report;

14. With multiple protection measures such as pressure overload and piston limit;

15. The external dimensions of the host bare metal (without sample sensor): about 3600×640×750mm.
