Microcomputer controlled electro-hydraulic servo universal testing machine
1. The gap mechanism makes the moving beam have the most reasonable working position and stress state.
2. Complete the test of steel, steel strand, cable, fasteners, concrete and other samples with relevant accessories.
3. The hydraulic clamping device can automatically adjust the clamping speed (the jog-type clamping device can be configured according to requirements)
4. The load sensor or oil pressure sensor can be selected autonomously to effectively improve the test range and force value accuracy.
5. The structure of the cylinder underneath installation can reduce the height of the main engine and the center of gravity of the test that could reduce the damage to the machine caused by the breaking impact.
6. Photoelectric encoder can accurately measure beam moving distance
7. The integrated oil source design makes the structure of the whole machine more compact and reasonable, reducing the floor space.
8. Manual and automatic dual control system is available, and the operation mode can be selected independently.
9. Built-in control card based on PCI technology, reduce connection wires, improve test real-time control and real-time acquisition function, improve product stability.
The main function
The testing machine can realize tensile, compression, bending and shearing of metal materials, non-metal materials and components with adding accessories. It also can realize closed-loop control of test force, displacement, deformation, stress and strain. The machine supports edit control mode by user. Built-in hundreds of standard modes could carry out data analysis according to standard requirements, and test results can be printed and networked.
1. The testing machine adopts microcomputer-controlled full digital wide-frequency electro-hydraulic servo control to drive precision hydraulic cylinders and automatically control various modes of test force, displacement and deformation to complete the tensile, compression and bending test of the specimen. It is confirmed to the requirements of national standards and other standards.
2. The main machine of the test machine adopts the hydraulic cylinder underneath install type, the power and transmission device for adjusting the test space are installed at the bottom of the machine, the transmission is stable, the upper and lower jaw seats are fully open structure, the automatic hydraulic clamping system, the clamping sample is convenient and stable.
1. Test sample information input:
The human-machine interaction method is used to analyze and calculate the mechanical properties of the test materials. At the end of the test, the elastic modulus, yield strength, non-proportional elongation stress, etc. are automatically calculated, which is intuitive and convenient, and can improve the accuracy of the analysis.
2. Test curve analysis:
Multiple force sensors and electronic extensometers can be configured at the same time. Users can switch between them as needed, and record force-time, deformation-time, force-deformation, stress-strain and force-displacement test curves in real time.
