Computer screen type hydraulic universal testing machine

Computer screen type hydraulic universal testing machine

The computer screen type hydraulic universal testing machine is mainly used for tensile, compression, bending and other mechanical properties test of metal materials. After adding simple accessories, it can test cement, concrete, brick, tile, rubber and its products.

This machine is composed of a four-column double-screw oil cylinder under-mounted high-strength main engine and a piano-type oil source control cabinet. The oil pump adopts a low-noise high-performance gear pump imported from Italian Marzucci. The tensile space is located above the main engine, and the compression and bending tests are located under the main engine, that is, between the middle beam and the workbench. The adjustment of the test space is realized by moving the middle beam, and the lifting and lowering of the middle beam is driven by a chain. Manually adjust the oil intake of the oil feed valve to realize the tensile, compression, bending and other tests of the material. After the test, the test results such as FM, REH, REL, RPO.2, RP1, RM and elastic modulus E of the material are automatically taken.


Features of Computer screen type hydraulic universal testing machine

1. When the special super-thick jaw seat is used to hold the sample in the jaw, the jaw is completely contained in the jaw seat, which makes the sample clamping more reliable, and eliminates the possibility of horn-shaped deformation and damage due to the shallow jaw seat. Improve the service life of the equipment.

2. A wear-resistant lining plate is added between the jaw seat and the jaw plate to prevent the oxide skin from falling in during the metal stretching process, resulting in scratches on the inclined surface of the jaw seat, making the clamping process smoother and the addition more reliable.

3. The measurement and control software is based on the Chinese windowsXP operating system platform, with fast running speed, gentle interface, menu prompts, mouse operation, and a variety of sample information input modes, which can meet the test of different materials. It can automatically generate batches of samples with the same conditions once input, and can also create condition templates.

4. The resolution of the test force display remains unchanged throughout the process to ensure the accuracy of the test data measurement.

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

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

7. Automatic overload protection and shutdown when the load exceeds 2%-5% of the full scale

10. According to the test date, the relevant historical records can be automatically inquired

11. The software reserves a database interface, which is convenient for local area networking between laboratories and convenient for experimental data management.
