WEW series screen display hydraulic universal testing machine

Main purpose

WEW series screen displayHydraulicUniversal testing machineIt is mainly used for mechanical property tests such as tension, compression, bending and shearing of metal materials.After adding a simple test tool, it can also test transmission chains, mining three-ring chains, high-strength bolt pairs, cement, concrete, rubber and their products.

This machine has a four-column, double-screw, and bottom-mounted oil cylinder main engine structure, and the control oil source is a piano-type oil source control cabinet.The tensile space is located above the main machine, and the compression, bending, and shear tests are located below the main machine, between the moving beam and the workbench.The adjustment of the test space is achieved by moving the position of the middle beam. The movement of the middle beam uses a gear reduction motor to drive a chain drive.Manually adjusting the oil inlet volume of the oil delivery valve can meet the adjustment of test speeds such as tensile, compression, and bending of the material.After the test is completed, the computer can automatically calculate the elastic modulus, tensile strength, upper and lower yield strength, specified non-proportional elongation strength, maximum force total elongation, post-break elongation and area shrinkage of the material, and can directly output standard test reports and test curves, and can also output statistical reports in EXCELL and WORD formats.

Performance characteristics

1. The main machine adopts a four-column high-rigidity frame structure, which has stable support, stable loading, and beautiful appearance;

2. The host base is made of QT500-7 precision casting to reduce equipment operating noise and improve equipment rigidity;

3. The moving beam and the upper beam are both precision cast and CNC precision machined to ensure the centering of the sample clamping;

4. The moving beam lifting system uses ground screws and precision gear reducers to reduce the noise generated when the beam is raised and lowered;

5. The specially designed jaw seat prevents damage due to trumpet-shaped deformation of the jaw seat and increases the service life of the equipment;

6. The hardness of the jaws is as high as 58-62HRC, which has the advantages of easy installation, strong and durable;

7. The measurement and control system runs fast, has a gentle interface, and has a variety of sample information input modes, which can meet the testing of different materials;

8. It is convenient to enter sample information, and the test of multiple samples can be completed by inputting the sample information of the same conditions at one time;

9. For samples under the same conditions, various test curves can be superimposed and displayed, and the stability of the material can be clearly identified;

10. The test force display has high precision, and the resolution of the test force display remains unchanged throughout the entire process to ensure the accuracy of experimental data measurement;

11. The test data (test force, loading rate) and test curve are dynamically displayed on the screen in real time along with the test process;

12. When the load exceeds 3-5% of the full scale, automatic overload protection shuts down.
