1 Overview
1. The micro-electro-hydraulic servo controller is used to automatically load and drive the hydraulic cylinder, and the load sensor detects the test force of the test piece. The performance is stable and reliable, and the data detection is accurate.
2. This testing machine is suitable for the test of specimens with a bearing capacity greater than 20kN and not greater than 600kN/1000 kN.
3. Comply with the national GT/T2611 "General Technical Requirements for Testing Machines" and the National Metrological Verification Regulations JJG139 "Tensile, Pressure and Universal Testing Machines" standards.
4. This testing machine is suitable for the compression and bending strength test of the manhole cover, which can meet the requirements of CJ/T3012-1993 "Cast Iron Manhole Cover", CJ/T121-2000 "Recycled Resin Composite Material Manhole Cover" and JC889-2001 "Steel Fiber Concrete Inspection" Manhole cover" and other related professional standards
2. Performance and Characteristics
1. The host adopts a high-rigidity structure to ensure safety during the test.
2. The loading cylinder is placed underneath, which is convenient to take and place the test piece of the well cover.
3. A spherical hinge type connection is used between the rigid pad and the piston push end to ensure complete contact between the manhole cover and the reaction plate and ensure the authenticity of the measured bearing capacity.
4. The oil cylinder and the piston are sealed with special materials to achieve the effects of high sealing, low friction and long life.
5. Using professional test oil pump motor unit, low noise and long life.
6. The ultra-precision oil filter is selected to ensure the cleanliness of the oil circuit system so as to ensure the long-term work of the control actuator.
7. Computer automatic control, real-time display of current force value, peak value, test process information, etc.
8. Real-time recording of test curves during the test process, high-speed sampling;
9. Data and report processing functions, providing users with special report editing tools for graphic typesetting, with the characteristics of flexible operation, simple and easy to learn, and convenient printing of test curves and test values;
10. The control mode has control functions such as constant velocity stress, constant velocity test force, test force retention, etc., as well as screen display functions of test force, peak value, piston displacement, and test curve. The test curve has force-time curve, force-deformation curve, and deformation- Time curve, smooth transition of control mode.
11. According to the needs of the experiment, the user can program by himself, automatic closed-loop control, cyclic loading, loading speed, loading waveform, (because the loading process stipulated by the standard is a cyclic waveform loading process), in short, it can realize each index step program of the national standard This enables the entire process to be automated without manual intervention. See the example for details.
12. The software sets the force value automatic clearing system, which eliminates factors such as human error in reading the meter.
13. With overload protection, when the force value or displacement exceeds the rated theoretical value of the testing machine, it will automatically unload or stop the test.
14. The failure load and deformation value are automatically collected and the report is printed.
