The WAW-2000B microcomputer controlled electro-hydraulic servo hydraulic universal testing machine is a product with strong universality, which can meet various standard tests in the national regulations on metal tensile testing. It can also perform tensile, compression, bending, shear and other types of tests on different materials or products according to other standards. It can obtain performance indicators such as tensile strength, yield strength, specified non proportional tensile strength, elastic modulus, etc. of the tested materials, and can achieve closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain. It can also conduct process qualification performance verification tests on materials or products.

The host of this product has a dual space structure, with a tension space between the upper and lower crossbeams and a compression space between the lower crossbeam and the test bench. The test space is automatically adjusted by the rotation of the sprocket and screw to drive the lower crossbeam up and down. The upper and lower crossbeams are equipped with wedge-shaped clamping jaws with built-in hydraulic control. Standard models are equipped with V-shaped and flat clamping blocks 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 pair, which can be directly used for compression testing.

The design of the mainframe of the testing machine considers the possibility of expanding and assembling other fixtures to complete more experiments. For example, bolt clamps can be used for bolt tension and load holding, bending clamps can be used for bending tests of round bars or plates, shear clamps can be used for shear strength tests of round bars, and anti bending, shear, splitting, elastic modulus instruments can be added in compression space to perform corresponding tests on concrete and cement samples. In addition, various tests of the product can be completed by using fixtures such as steel balls, anchor chains, and fasteners.

Product Features
————————————————————

The host of the WAW-2000B microcomputer controlled electro-hydraulic servo universal testing machine is a six column frame structure, with the main oil cylinder placed below. The main structure consists of a base, oil cylinder, test bench, lower crossbeam, upper crossbeam, screw, light bar and other components. The base is equipped with a screw drive and transmission mechanism, which adjusts the test space by driving the lower crossbeam up and down through the rotation of the screw. The end of the main oil cylinder piston is equipped with a load sensor. The oil cylinder rises through high-precision load sensors, a test bench, a column, and an upper crossbeam to complete stretching. The same action can be used to complete compression tests between the test bench and the lower crossbeam.

The machine design takes into full consideration aesthetics, convenience, and safety, for example: jog the lower crossbeam up and down buttons on the manual operation box for flexible control, easy and fast adjustment of the test space; Fully open wedge-shaped jaws, the clamping force of the specimen increases synchronously with the tensile force, ensuring reliable clamping and convenient cleaning of the jaws; The surface of the light bar is chrome plated and polished, beautiful and rust proof; A built-in small oil cylinder is installed at the jaws of the upper and lower crossbeams, which is safer, more reliable, has a longer lifespan, does not leak oil, has a beautiful appearance, and is easier to operate than an external clamping oil cylinder.
