Computer Control Electro-hydraulic Universal Testing Machine

1.Application:

Servo Hydraulic Universal Tensile Tester is mainly used for metal and non metal materials tensile, the test of mechanical properties of compression,bending and shear,tension,

compression,bending,shearing,peeling,tearing and other tests by adding different test fixture for metal and non-metal materials. It is widely used in inspection department, 

engineering area, laboratories, universities and institutes for material properties research and quality control.

4.Features:

1. It has three parts: Host & oil source &measurement control system 

2. Automatic rise, down, test and stop

3. Deepen jaw seat can prevent trumpet-shaped deformation as non-uniform stress in the test, can improve the soundness and life, make holding more firm and smooth

4. Between the jaw seat and jaw plate added wear-resisting backing board, protect the jaw seat and card plate, making the jaw seat more flexible

5. Between the host base and screw using the cone bearing which make screw rotation more stable and reliable, while solved the gap influence in the test progress

6. The middle cross bar adopt the adjustable gap nut mechanism, eliminated the gap and improve the measuring performance

7. All inclusive type host designed to ensure that its super stiffness to resist loads trace deformation

8.Dual control modes: PC control and manual control

9.Silent internal high pressure gear pump with noise below 65db under max. load. With pressure follow-up technology, the hydraulic system pressure follows the working pressure in oil cylinder for all the time to save energy

10.Dual test space design with oil cylinder at the bottom; Compact structure with four-column and two-ball screw

11.Hydraulic grips for easy gripping of specimens with no slippage and special grips can be ordered for shoulder s pecimen, threaded specimen or steel strand specimen

12.Chroming columns for long service life

13.Manual hand control box for convenient and flexible operation

14.High precision spoke type load cell to measure load with high anti-lateral and anti-impact ability

15.Silent internal high pressure gear pump with noise below 65db under max. load. With pressure follow-up  technology,  the hydraulic system pressure follows the working pressure in oil cylinder for all the time to save energy

16.Advanced and reliable PCI interface technology speeds up data acquisition, control signal response and raises control accuracy. The PC can automatically judge the specimen characteristic to finish a perfect test easily
