WAW Series Computerized Electro-hydraulic Servo Universal Testing Machine (300kN,600kN,1000kN,2000kN)

WAW Series Computerized Electro-hydraulic Servo Universal Testing Machine (300kN,600kN,1000kN,2000kN)

 

1. Introduction

This WAW Series Computerized Electro-hydraulic Servo UTM is fully computer controlled; the testing dates and testing curves can be displayed by computer and printed by printer.

It is widely used for tensile, compression, bending and shearing test for metal materials and also used for compression and bending test of non-metal materials, like cement and concrete materials. With special accessory, it can also be used for mechanical property test of fastener, steel wire rope and components .The machine is calibrated according to ISO 75001 and ASTM E4. It can do many different kinds of test according to different standards, ISO6892, ISO7438, ASTM A370, ASTM E8 and BS EN standards.

3. Features

3.1 Control type: computer controlled servo hydraulic universal testing machine. The space adjusting, & test processes could be controlled by the software and the test result could be transferred to the software in the computer for further analysis. It is the most advanced series in hydraulic universal testing machines.

3.2    Load measurement: high-precision oil pressure sensor, high-precision oil tank piston; they ensure the high precision and high reliability.

3.3    Displacement measurement: photoelectric encoder, high-precision, reliable.

3.4    Deformation measurement: high-precision strain extensometer is reliable and economical.

3.5    Automatic clamping: single hydraulic clamping oil supply; automatic and reliable clamping, high safety.

3.6    Multiple protection: double protection for hardware and software; double protection piston travel for mechanical and electric; protect itself automatically when exceeding 2~10% of Max. load.

3.7    Automatic calibration: calibrate the load, deformation and displacement automatically.

3.8    Getting the test results: get the ReH, ReL, Fm, Rp0.2, Rt0.5, Rm, E results automatically.

3.9    Management of database: manage the test machine software by Access database.

3.10 Reserve the data interface, can be connected with Internet directly and share the resources.

3.11 Compact structure: more reasonable structure. Lowering the height that the test space is same.

3.12 Multiple control modes: force, displacement and deformation three closed-loop, multiple controls that contain metal tensile test and so on. The professional “Control program editor” software, which is customized by the uses’ actual needs.

3.13 Worm gear and worm wheel: The adjustment of the testing space (up and down of the crossbeam) is drive by an electric motor. It adopts worm gear and worm wheel structure; there is no need to rotate the screw when adjusting testing space. The complete separation between transmitting system and positioning system ensures the coaxiality of the up and down jaws.
