Product Profile:

• WAWD-1000B electro-hydraulic servo universal testing machine is a high-precision material testing equipment, which adopts hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can realize closed-loop control and automatic detection. It consists of four parts: test main engine, oil source (hydraulic power source), measurement and control system and testing equipment. The maximum test force is 1000kN, and the accuracy of the testing machine is 1000kN. Grade 1 is better than grade 1.

• WAWD-1000B electro-hydraulic servo universal testing machine is a universal product, which can meet various national standards for metal tensile test. It can also carry out tensile, compressive, bending and shear tests of different materials or products according to other standards. It can obtain the tensile strength, yield strength and non-proportional extension of the tested materials. Strength, modulus of elasticity and other performance indicators can achieve closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, constant rate strain, etc., and can carry out process qualification test of materials or products.

• The test machine is a six-column, double-space structure, with tension space between the upper and lower beams, and compression space between the lower beams and the test bench. The test space is automatically adjusted by rotating the lower beams with sprockets and lead screw. The upper and lower crossbeams are equipped with hydraulic clamping jaws, and the standard models are equipped with V-type and plane-type jaws to clamp the cylindrical and flat specimens for tensile test; the bottom of the lower crossbeams of the standard models are equipped with an upper pressure plate, and the test bench is equipped with a lower pressure plate with spherical structure, which can be directly used for compression test.

• The design of the main engine of the test machine considers the possibility of expanding the assembly of other fixtures to complete more tests. For example, bolt fixture can be used for bolt tension and loading, bending fixture can be used for bar or plate bending test, shear fixture can be used for bar shear strength test, concrete and cement sample test can be done by adding bending, shearing, splitting and elastic modulus meter in compression space, in addition, steel ball, anchor chain, fastener and other fixtures can be used to complete the product. Item test.
