Microcomputer controlled hydraulic universal testing machine

1、 Introduction:

Microcomputer controlled hydraulic universal testing machineMainly used for testing the mechanical properties of metal materials such as tension, compression, and bending. With the addition of simple accessories, it can be used to test cement, concrete, bricks, tiles, rubber, and their products.

This machine is equipped with dual columns（Or four column double）The main unit consists of a screw oil cylinder and a piano type oil source control cabinet. The stretching space is located above the host, and the compression and bending tests are located below the host, between the middle crossbeam and the workbench. The adjustment of the experimental space is achieved by moving the middle crossbeam, and the lifting of the middle crossbeam is driven by a chain. Manually adjust the oil inlet volume of the oil delivery valve to achieve material stretching, compression, bending and other tests. After the experiment is completed, the material's force, tensile strength, and other test results will be automatically obtained.

2、 According to standards;

satisfyGB/T228-2020Standard requirements for metal tensile testing. The electrical system has three control modes: force control, deformation control, and displacement control. During the testing process, the three control modes can be smoothly switched according to the set program. The software can automatically calculateREH(Upper yield strength)REL(Lower yield strength)TheRp0.2(Specify non proportional extension strength)Rt0.5(Specify the total elongation strength)RM(Tensile strength)E(Elastic modulus) and other parameters.

3、 Performance characteristics:

1Microcomputer controlled hydraulic universal testing machineThe ultra thick jaw seat accommodates the jaws inside the jaw seat when clamping the sample, making the sample clamping more reliable and reducing the possibility of trumpet shaped deformation and damage due to shallow jaw seats, greatly improving the service life of the equipment.

2. A * * * lining plate has been added between the jaw seat and the jaw clamping plate. During the metal stretching process, the oxide scale falls in, causing scratches on the inclined surface of the jaw seat, making the clamping process smoother and the addition more reliable.

3. The measurement and control system has fast running speed, gentle interface, and multiple sample information input modes, which can meet the testing needs of different materials. For samples with the same conditions, multiple inputs are automatically generated at once.

4. The experimental force display maintains the same resolution throughout the entire process to ensure the accuracy of experimental data measurement.

5. The test data (test force, loading rate) and test curve are dynamically displayed in real-time on the screen during the test process.

6. After the experiment, the experimental data will be automatically analyzed, stored, and printed.

7. When the load exceeds 2% of the slow range - * * *, it is automatically overloaded and the machine stops.

8. The decomposition test date can automatically query relevant historical records.

9. Software reserved data interface, convenient for laboratory interval local area networking, and easy for experimental data management. Technical parameters of WE-B series digital hydraulic testing machine
