Micro-Computer Controlled Steel Strand Tensile Testing Machine
GAW-1000B type micro electromechanical servo steel strand tensile testing machine is a high-precision material testing equipment that uses hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can realize closed-loop control and automatic detection. The main engine, oil source (hydraulic power source), measurement and control system, and test equipment are composed of four parts. The maximum test force is 1000kN, and the accuracy of the test machine is better than level 1.
GAW-1000B type micro electromechanical servo steel strand tensile testing machine can meet the national standard test requirements of steel strand tensile test regulations, and can obtain the tensile strength, elastic modulus and other performance indicators of the tested materials.
The testing machine is a six-column, double-space structure. There is a stretching space between the upper beam and the lower beam. The compression space between the lower beam and the test bench is used. The test space moves the lower beam up and down through the rotation of the sprocket and the screw. auto-adjust. Hydraulically controlled clamping jaws are mounted on the upper and lower beams, and the special clamps for steel strands can be used for tensile testing of steel strands of Φ8 to Φ18mm; the bottom end of the lower beam of the standard model is equipped with an upper pressing plate, on the test bench. It is equipped with a lower plate with a spherical structure for direct compression testing.
