WAW-D series microcomputer controlled electro-hydraulic servo universal testing machine

This machine has a four-column, double lead screw, and a cylinder-mounted main machine structure, and the control oil source is a piano-type oil source control cabinet. The tensile space is located above the host, and the compression, bending and shear tests are located below the host, that is, 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 reducer motor to drive the chain transmission. The computer automatically controls the servo valve to complete the loading process of the sample, and has a variety of automatic control methods such as constant rate test force, constant rate deformation, and constant rate displacement. Smooth switching can be achieved between various control methods. The independent external controller and strong electric control system provide strong guarantees for the stable operation of the equipment. After the test is completed, the computer can automatically calculate the test results of the material's elastic modulus, tensile strength, upper and lower yield strength, specified non-proportional extension strength, maximum force total elongation, after-break elongation and cross-section shrinkage, and can directly output standard test reports and test curves, orEXCELL and WORD format output statistical reports.

Performance Features

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

2. The host base is precision cast using QT500-7 to reduce equipment operation noise and improve equipment rigidity;

3. Both the moving beam and the upper beam are precision cast and CNC precision machining to ensure the neutrality of the sample clamping;

4. The mobile beam lifting system uses grinding lead screws and precision gear reducers to reduce the noise generated when the beam lifts and lowers;

5. The jaw seat with a special structure is designed to prevent damage caused by the jaw seat in a trumpet-shaped deformation and improve the service life of the equipment;

6. The jaw adopts a dovetail groove structure, with a hardness of up to 58-62HRC, which has the advantages of convenient installation and durability;

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

8. The sample information is convenient to enter, and the sample information of the same conditions can be input at one time to complete the test of multiple samples;

9. Samples with the same conditions can be superimposed on various test curves, which can clearly identify the stability of the material;

10. The accuracy of the test force and deformation display is as high as 1/500,000, and the full range display resolution remains unchanged to ensure the accuracy of measurement;

11. Test force, displacement, deformation, loading rate and various test curves are displayed dynamically in real time on the screen as the test process;

12. The loading method of the test process can be controlled by free editing programs according to the customer's idea;

13. The experimental results can realize resource sharing among local networks;

14. Automatic overload protection shutdown when the load exceeds 3-5% of the full scale.
