It consists of four parts: test host, oil source (hydraulic power source), measurement and control system, test equipment, maximum test force 2000kN, accuracy of the testing machine. Grade 1 is better than grade 1.

• WAWD-2000B 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 wedge-shaped clamping jaws with built-in hydraulic control, and the standard models are equipped with V-shaped and plane-shaped clamps to clamp cylindrical and flat specimens for tensile tests; the bottom of the lower crossbeams of the standard models are equipped with upper pressure plates, and the test bench is equipped with lower pressure plates with spherical structure, so that compression tests can be conducted directly.

• 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.
