It is mainly used for tensile, bending, compression, shearing, peeling and tearing tests of various metallic and non-metallic materials.

Characteristics:

1. 1. Adopts four-column frame (WAW-100B and WAW-300B) structure and six-column frame (WAW-600B and WAW-1000B) structure with lower cylinder, good rigidity and stable structure.
2. 2. Adopts hydraulic automatic clamping
3. 3. Adopts class C3 high precision plunger type weighing transducer, Not affected by temperature, it has the characteristics of high accuracy, good stability and good output linearity. The accuracy error of force indication is ≤1%.
4. 4. Adopts high precision displacement sensor
5. 5. Adopts high precision extensometer for deformation
6. 6. Adopts high performance servo valves for control
7. 7. The double-nut reverse clearance elimination structure is adopted to solve the problem of crack enlargement of parts caused by wear and tear of nuts during long-term operation. The loading rate is guaranteed, which is much higher than the standard of GB228.
8. 8. Can realize constant rate force control, constant rate stress control, constant rate strain control, constant rate stroke control, low cycle fatigue control and user self-programming control, etc.

   9. Can make curves like: force-deformation, force-displacement, stress-strain, force-time, etc

   10. The networked measurement and control system has the functions of gain adjustment and zero fullness to ensure the smooth operation and accurate measurement of the machine.

   11. Adopt PCI Bus Control Mode

   12. Adopts imported product for hydraulic system, for example imported Siemens motor and imported radial plunger pump, makes higher precision, lower noise, better durability, enhance the machine stability.

   13. The computer and electro-hydraulic servo system are used to control loading and fully automatic control. According to the preset stress rate and curve form, the test can be completed independently, and the load, speed, time and test curve can be displayed dynamically. All the tests can be completed by setting only one parameter.

   14. Equipped with the current advanced industrial embedded tablet computer, The withstandable voltage range is 85-250V, and the anti-interference performance is stronger.

   15. Adopts touch screen computer. Operating by touch screen and keyboard.

   16. With Windows software, can automatically get the elastic modulus E, upper yield strength ReH, lower yield strength ReL, stipulated non-proportional extension strength Rt, yield point elongation, etc

   17. Automatic data acquisition and processing by computer and synchronous screen display of test data and curve are adopted. The experimental curves can be enlarged locally and compared by superposition of multiple curves. It has the functions of disk storage, printing test results and test curves of test results, report processing of batch test results, database management, etc. It also has network interface, LAN networking function and seamless remote data connection function.
