★main purposeand brief introduction
1. This machine is mainly used for steel strand anchorage in railway, highway, bridge, and water conservancy infrastructure construction; Static load anchoring efficiency coefficient, ultimate tensile total strain, anchor plate strength, and cyclic load performance tests for fixtures and connectors. The prestressed anchor components can be tested according to the standard requirements of GB/T14370-2007 "Anchors and Fixtures for Prestressed Reinforcement" under servo control conditions.
2. It has two control channels for load and displacement, as well as three corresponding control modes for force, stress, and displacement. The control modes can be randomly/arbitrarily switched between them. PID parameters can be adjusted online.
3. It can perform equal rate load, stress, displacement control and constant load, stress, displacement control, and adopt stepless speed regulation.
4. Automatically draw various test curves such as force displacement, force time, displacement time, etc., automatically edit test reports and print them out in a timely manner;
5. The measurement system has automatic zeroing and calibration functions, and continuous measurement throughout the entire process without grading.
6. Group style multi-color curve comparison tests can be conducted, and any segment on the test curve can be selected for regional amplification analysis. During the test process, various test curves can be switched and displayed;
7. It has a powerful database and multiple interface formats for users to choose from, helping them achieve local area network communication;
8. It has multiple protective measures such as pressure, oil temperature, and piston limit;
