wide usage hydraulic universal testing machine - WEW

Our company manufacture various types of universal testing machine to guests all over the world.

Functions and Technical Parameters

1. Host machine:

A. Specification and model: WEW-600B (see the right picture);

B. Introduce Japanese host machine technology with oil cylinder lower placed (the oil cylinder is casted in integral and sealed by grinding the space in precision, characterized in small friction and stable property etc.). The stretching space lies above the host machine, the compressing and bending testing spaces are between the lower beam and the workbench of the host machine.

2. Testing force measurement:

A. Range of testing force measurement: 24-600KN;

B. Precision of indicating value of the testing force: ±1% of the indicating value;

C. Resolution ratio of testing force measurement: 0.005%FS

3. Deformation measurement:

A. Range of deformation measurement: 4%-100%;

B. Precision of indicating value of deformation: ±1% of the indicating value;

C. Resolution ratio of deformation measurement: 0.01mm

4. Displacement measurement:

A. the photoelectric encoder measures the travel distance of piston;

B. Relative error of displacement indicating value: ±1%;

C. Resolution ratio of displacement measurement: 0.005mm

5. Clamping mode: semi-open chuck, independent hydraulic clamping

6. Maximum stretching testing space: 650mm

7. Maximum compressing space: 600mm

8. Travel distance of piston

9. Clamping thickness and width of flat test piece: 0-30×75mm

10. Clamping diameter of round test piece: φ13-φ40mm

11. Maximum space between bending fulcrum: 360mm

12. Distance between vertical posts at two sides: 450mm

13. Dimension of upper and lower pressing plates: φ160mm

14. Transmission system: the lifting of lower beam is transmitted by hydraulic motor, gears, nuts and screws to realize the adjustment of stretching and compressing spaces.

15. Hydraulic system:

A. The hydraulic oil in the tank enters the oil channel by the motor driving high pressure gear pump and enters the tank by flowing through the one-way valve, 10μ high pressure oil filter and differential pressure valve blocks.
