Electro-hydraulic servo universal material testing machine

WAWD-300B Electro-hydraulic Servo Universal Material Testing Machine Product Introduction
WAWD-300B electro-hydraulic servo universal testing machine can meet the national standards for metal tensile test, but also according to other standards to achieve different materials or products tensile, compression, bending, shear and other types of tests.
WAWD-300B 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 host, oil source (hydraulic power source), measurement and control system and test instrument. * The maximum test force is 300kN.
WAWD-300B type electro-hydraulic servo universal material testing machine is a six-column, double-space structure, between the upper beam and the lower beam for tension space, between the lower beam and the test bench for compression space, the test space through the sprocket and screw rotation to drive the lower beam up and down to automatically adjust. The upper and lower beams are equipped with hydraulically controlled clamping jaws. The standard models are equipped with V and flat jaws for clamping cylindrical specimens and flat specimens for tensile tests. The bottom of the lower beam of the standard models is equipped with an upper platen. The test bench is equipped with a lower platen with spherical structure for direct compression tests.
