8. Displacement (deformation) Measuring range and accuracy: 0-2200mm; accuracy better than ± 0.1mm

9. Test loading speed: ≥ 150mm / min

10. Load beam quick adjustment speed: ≥250mm / min

11. Control mode: constant test force control / constant displacement control;

12. Fixture: Plug-type fixture with a special packing with tensile fixture

13. Sectional sliding translating shield (direct protective length of about 5 meters, indirect protective length of 10 meters)

14. Testing machine host dimensions (length x width x height mm): about 15500x1320x620 mm (without protective cover);

15. Test machine hydraulic system power: about 7.5 kW.

1.3 GB / T2611-1992 "test machine general technical requirements"

2. High-precision closed-loop electro-hydraulic servo control design, test process control automation, high precision measurement and control.

3. Load-sensitive hydraulic circuit design, energy-saving effect is obvious

4. Configuration of hydraulic oil temperature control system to meet the requirements of long-term operation of large loads

5. Stitching high stiffness bearing frame design, light weight, good stability

6. The overall integration of the host design, installation, mobile convenience, good protection for the cylinder cylinder rod

7. Have the perfect protection function:

A) cylinder limit protection;

B) hydraulic system overload, overflow, dirty block protection

C) Test force overload protection

D) circuit system over-current, over-voltage protection

E) Specimen breaking protection

F) Safety warning display: When the loading beam load exceeds the set value, the warning indicator will be lighted automatically.

8. Segmented safety shield.

9. Computer and electrical control system functions and features:

9.1 The use of brand microcomputer, special testing machine software can be based on national standards to complete the test force, displacement of a variety of modes of automatic control to complete the test process parameters of the test set, test process control, data acquisition, processing, analysis and display , Accurate realization of constant displacement control, constant speed test force control;

9.2 Test Force, Peak, Specimen Deformation, Piston Displacement, Test Curve Screen Display Function, Full Keyboard Input Operation and Control Mode Intelligent Setting Special System to achieve smooth switching between various control modes to make the system have maximum flexibility Sex;

9.3 perfect test curve graphics processing functions: the curve of the test process can automatically track and adjust, to print, save the curve, the curve can be partially enlarged, you can also zoom in full-screen, you can track the curve view, observe the data;

9.4 powerful report processing functions: the report can print, save, preview, data can automatically fill in the report. Users can customize the report format according to requirements, and convenient, intuitive, which is generally not available in the test machine software;
