1000 kn Computer Controlled Electro Servo Hydraulic Universal Tensile Testing Machine is

applicable to metal, cementing compound, tubes, sectional bars, aerospace, petrochemical, waterproof rolls, wire and cable, textile, fiber, rubber, ceramics, food, mechanical packaging, geo-textile, film, wood, paper and other industries and quality supervision department, and it also can be used in college for teaching demonstration.

Adopting precise auto control and data acquisition system to realize fully digital adjustment to data acquisition and control process. During tensile test, it can test max. bearing tensile, compression, tensile strength, deformation, elongation and other technical specifications;

After tensile test, the above parameters can be calculated automatically through main controller according to the test parameters, which are set before test and meantime display the corresponding test results. All test parameters can be saved and inquired after test, also can be connected with printer to print test reports.

Standards

GB/T228.1-2010, ISO and ASTM standards.

Functions

1. Adopting 4-clomun, double-space frame structure, with big stiffness and good stability; automatic hydraulic clamping methods, easy and reliable to clamp the samples.

2. There’s a spring cushion device in the mid-beam, which can effectively eliminate the transmission clearance between the screws and the nuts, also can do good cushioning effects when the samples are broken.

3. There’re high toughness protection network, which can effectively ensure the safety of the operator.

4. High precision load cell ensure the measuring accuracy of the testing machine.

5. The latest servo pump control technology to ensure the low noise, strong anti-pollution ability, and a long time works without fault.

6. PID control achieve three closed loop control on the load, displacement and deformation, also can smoothly change controls.

7. It can easily add or delete a test standard, control procedures can be freely edited according to the test requirements.

8. It can real-time display the test curve, the curve coordinates can be freely selected (3 different curves can be displayed at the same time in the same window), the test curve can be partially enlarged displayed.

9. It can automatically calculate max. force, tensile strength, yield strength, non-proportional elongation strength, elastic modulus, break down elongation percentage and other parameters, also can print out the complete test report.
