GAW-1000B microcomputer electro-hydraulic servo stranded tensile testing machine is driven by the hydraulic power source, the electro-hydraulic servo control technology, computer data collection and processing, can realize the closed loop control and automatic detection of high-precision materials testing equipment, its by the test host, oil source (hydraulic power source), measurement and control system, test instruments of four parts, the biggest test force 1000 kn, testing machine precision is better than that of grade 1.
The tensile testing machine of steel strand meets the standard test requirements of the tensile test of steel strand. It can obtain the tensile strength, elastic modulus and other performance indexes of the measured material.
The testing machine is a six-column, double space structure, between the upper beam and the lower beam for stretching space, between the lower beam and the test table for compression space, the test space through the sprocket and lead screw mother rotation driven under the beam up and down to automatically adjust.Upper and lower beam is equipped with hydraulic control of the clamping jaw, special steel strand jaw can be configured for Φ 8 to Φ18 mm tensile test of steel strand;The bottom end of the lower beam of the standard model is equipped with the upper pressure plate, and the test table is equipped with the lower pressure plate with a spherical structure, which can be directly compressed test.
