1. Equipment Usage
The WAW series electro-hydraulic servo universal testing machine displays force values and curves through a computer. The product is used for tensile, compression, bend and shear tests on metallic materials. In addition, it is able to do fracture resistance and compression resistance tests on cement, concrete and other non-metallic materials. With the help of special-purpose auxiliary tools, it also applies to mechanical property tests on fasteners, steel wire ropes and constructional elements. Therefore, it is ideal for aerospace departments, project quality testing, colleges, industrial and mining enterprises, and research and development institutions. In order to satisfy your varied demands, the machine supports testing in accordance with several test standards, like ISO, ASTM, JIS and EN. Its force measurement range covers 300kN, 600kN, 1000kN and 2000kN.

3. Key Features of Electro-hydraulic Servo Universal Testing Machine
1) Compact Structure
The structure is compact and reasonable with a hydro-cylinder underneath the main engine. You can easily install the product.
2) It adjusts test space through worm drive mechanism that traverses moving beam. This design is able to adjust test space without revolving the screw, absolutely separate drive system from positioning system, and make sure the geometric center of loading system accords with the center of stressed position, which contributes to the concentricity between upper and lower jaws, and wear of the main engine. The unique elimination mechanism of screw clearance enables tests to be loaded continuously.
3) Load Measurement
The electro-hydraulic servo universal testing machine is praised for the high-accuracy oil pressure sensor, high linear repeatability, considerable shock resistance, great stability and long working life.
4) Displacement Measurement
The imported optical-electricity encoder guarantees precise and steady displacement measurement.
5) Deformation Measurement
The strain extensometer is applied due to high precision, cost saving and practical application.
