Main uses and functions
This model of electro-hydraulic servo universal testing machine is a high-precision material testing equipment that adopts hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can achieve closed-loop control and automatic detection. It consists of four parts: the testing host, oil source (hydraulic power source), measurement and control system, and testing instruments. The maximum testing force is 1000kN, and the accuracy level of the testing machine is better than level 1.
This model of electro-hydraulic servo universal testing machine is a product with strong universality, which can meet the various standard tests specified in the national regulations on metal tensile testing. It can also achieve tensile, compression, bending, shear and other types of testing for different materials or products according to other standards. It can calculate the tensile strength, yield strength, specified non proportional elongation strength, elastic modulus and other performance indicators of the measured materials. It can achieve closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain, and can conduct process qualification performance verification tests for materials or products.
The testing machine has a dual space structure, with a stretching space between the upper and lower crossbeams, and a compression space between the lower crossbeams and the test bench. The testing space is automatically adjusted by driving the lower crossbeams up and down through the rotation of sprockets and screw rods. Hydraulic controlled clamping jaws are installed on the upper and lower crossbeams, and standard models are equipped with V-shaped and flat jaws for clamping cylindrical and flat specimens for tensile testing; The bottom end of the lower crossbeam of the standard model is equipped with an upper pressure plate, and the test bench is equipped with a lower pressure plate with a spherical structure, which can be directly used for compression testing.
