The WAW-B microcomputer controlled electro-hydraulic servo universal testing machine is a universal hydraulic universal testing machine, which adopts hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can achieve high-precision material testing equipment with closed-loop control and automatic detection. It consists of four parts: the testing machine host, oil source (hydraulic power source), measurement and control display system, and testing fixture.
This testing machine is a universal product, with a dual testing space structure for the main unit. The tension space is between the upper and lower crossbeams, and the compression space is between the lower crossbeam and the test bench. The testing space is automatically adjusted by driving the lower crossbeam up and down through the rotation of sprockets and screws. The upper and lower crossbeams are equipped with wedge-shaped clamping jaws controlled by external hydraulic pressure. Standard models are equipped with V-shaped and flat clamping blocks for clamping circular 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, which can directly perform metal and rubber compression tests.
