الحواسيب الصغيرة التي تسيطر عليها الكهربائية والهيدروليكية فتحة آلة الاختبار العالمي ( دوبلكس )

The full digital closed loop control system can realize the requirements of three closed loop control of load, displacement and deformation, and the control modes can be arbitrarily combined and smoothly switched;

Fully meet the requirements of GB/T 228 metal material tensile test method at room temperature, suitable for metal bars, plates, rebar and fasteners and other test tensile test automatically obtain the result parameters specified in the relevant standards (need to configure the corresponding fixture or deformation measuring device);
The software meets GB/T 17671, GB/T 50081, and is suitable for compressive test and bending test of cement mortar sample and concrete sample (with appropriate measuring range);
The software meets GB/T 232 and is suitable for bending test of metal materials;
Measuring range :200kN-2000kN.

Features:
1. Host structure
Double space structure. Tensile test was carried out on the upper space. Lower space compression test. Compact structure. The layout is reasonable. It can be adjusted easily. Both the upper and lower beams in the test space are cast steel parts. High strength. Good security.
2. Hydraulic fixture
Open hydraulic closure. Easy to hold. Clamping force is adjustable.
3. Test force measurement
Pressure load sensor is used. Up to 0.5 class accuracy.
4. Displacement measurement
Adopt imported withdrawable displacement sensor.
5. Piston limit
The protective piston cannot move out of range.
6. Control system
Full digital DSP controller. Neuron adaptive PID algorithm. Force, extensometer (deformation), displacement three closed loop control, up to 8 analog signal acquisition channels. 3 digital signal control channels.
7. Test the software
Professional modular test software. Meet the test requirements of national, international and industry standards. Realize the network transmission of test data.
8. Oil source
It has a quiet design. Environmental protection. Humanize. Unique differential pressure servo system reduces energy consumption. Reduce fever. Protect the oil circuit.
